Corresponding author *: Keywords: Power generation, heat recovery, waste heat, thermoelectric, heat pipe 1. Abstract This study looks at unique method of recovering industrial waste heat and converting it to electricity using a combination of heat pipes and thermoelectric generators (HPTEG). This paper presents design of a bench top system for this purpose. The system consists of a thermoelectric generator (TEG) sandwiched between two finned heat pipes heat sinks, one is connected to the hot side of the TEG and the second is connected to the cold side of TEG. A theoretical model has been developed and presented in the paper to predict the performance of such a waste heat recovery system. Initial theoretical predictions have shown that the 8 modules of HPTEG are capable of recovering about 1.9 kw of waste heat and produce 26W of electrical power. 2. Introduction The need for clean and renewable energy has attracted growing attention on technologies that can reduce greenhouse gas emission. Recent times the focus on using free and cheap energy such as waste heat has increased. If the waste heat is recovered and converted to electricity then the overall system efficiency of the conventional energy conversion system can be improved. Waste heat at temperatures below 14 C can be a competitive source for generating electricity [1]. One of a practical method to utilise the industrial waste heat is by using thermoelectric generator (TEG) for electrical power generation. A thermoelectric power generator (TEG) is a device that can convert thermal energy into electricity using Seebeck effect. It is a solid-state heat engine and has no moving parts, no vibration, no noise, light in weight and very reliable [2]. To generate electrical power, a thermoelectric cell (TEC) is sandwiched between a heat source and a heat sink. Because of the temperature gradient, heat will flow through the module and is rejected to ambient through the heat sink. If the temperature gradient is maintained, the electric power will be continuously generated [3]. A combination of heat pipe and thermoelectric generator was studied by Singh, R., et al. [4]. This research used a fully passive system that extracted heat from a solar pond and the system managed to produce 3.2 W from 16 TEG modules, 211

2 while the temperature different across the modules was maintained at 27 C. Kim, S., et al., installed TEG on I.C. engine cooling system of a passenger car [5]. The maximum power output from this system was 75 W. The calculated module efficiency was ~2.1% and the overall efficiency of electrical power generation was ~.3% in driving mode at 8 km/h. Kim, S.K., et al., investigated thermoelectric power generation by using hot exhaust gas from hybrid vehicles [6]. Thermoelectric cells and heat pipes were used to withdraw heat from small surface area of a hot exhaust pipe. To increase efficiency, an enlarged surface was designed by adding 1 more heat pipes. This system managed to produce 35W for an evaporator surface temperature at 17 C. Goncalves, L., et al. utilized a variable conductance heat pipe (VCHP) to regulate high temperature from engine exhaust gas. This heat pipe (VCHP) was also used to control TEG operating temperature [7]. It was expected that the system could produce 55 W electrical power output for an input power above 3 kw. Most of the previous studies have only investigated power generation using TEG and none of them have considered recovering the released heat from the cold side of TEG for other uses [4-7]. However, this study introduces a new concept of sandwiching TEG with heat pipes which it will be a totally passive heat transfer system. It focuses not only on the electric power generation but also will look at the amount of heat that can be recovered from the wasted heat. 3. Description of the System A theoretical model was developed to predict the performance of waste heat recovery and conversion to electricity systems using Thermo-Electric Generator (TEG). This theoretical model was based on our bench top system as shown in Fig. 1. The bench consists of TEG sandwiched between two heat pipes which they act like an evaporator (heat pipe 1) and a condenser (heat pipe 2). The TEG surfaces are heated and cooled by heat pipe 1 and heat pipe 2, respectively. These processes will create temperature gradient across TEG for generating electric current. Fig. 1. Proposed concept of combined heat pipe thermoelectric generator (HPTEG). 212

3 The basic concept of heat pipe thermoelectric generator (HPTEG) is shown in Fig. 2(a). It contains a rectangular finned tube heat pipes that are attached with copper blocks. Soldering is used to thermally bond between the heat pipes and copper blocks. A thermoelectric generator (TEG) is sandwiched between two copper blocks as shown in Fig. 2(b).

4 4.1 Energy Balance Equations Referring to Fig. 3, cold air enters from the upper part of the duct in the x direction and exits from the bottom part of the duct (+x direction) and the energy balance can be written as: π‘šπΆ! #!!! 𝑑π‘₯ = π‘šπΆ! #!!! 𝑑π‘₯ (1) Where 𝑇! and 𝑇! are the cold and hot air temperatures, respectively. π‘š is the air mass flow rate, 𝐢! # is the specific heat capacity of air and 𝑑π‘₯ is the length increment in x-direction. The rate of energy transfer from lower duct through HPTEG is determined using the follow equation: π‘šπΆπ‘#!!! 𝑑π‘₯ = (𝑇! 𝑇! )/𝑅! (2) Where 𝑅! is the total thermal resistance of HPTEG. Heat is added to the system by using an electric heater and is calculated as follows: π‘šπΆ! 𝑇! 𝑇! = 𝑄 (3) Where 𝑄 is the rate of heat added to the system. By solving equations (1), (2) and (3), the temperature profiles of hot and cold air in the upper and lower duct can be determined using equation (4) and (5). 𝑇! π‘₯ =!!!!!! +𝛽 (4) 𝑇! π‘₯ = 𝑇! π‘₯ 𝛼 Where 𝛼 = 𝑄 /π‘šπΆ!, 𝛽 = 𝑇 + 𝛼(1 + (5)!!!!! ), 𝐿 is the duct length, and 𝑇 is the inlet cold air temperature. The total rate of heat transfer through the HPTEG heat exchanger is finally represented by: 𝑄! = (6)!! Referring to Fig. 4 and Fig. 5, 𝑅! is the total thermal resistance for a single module of HPTEG and is defined as: 𝑅! = 𝑅#! + 2𝑅!#!# + 2𝑅#$%& + 2𝑅##$% + 2𝑅# + 𝑅# + 𝑅# #$ (7) Where 𝑅#!/#$,𝑅!#!#, 𝑅#$%&, 𝑅##$%, 𝑅# and 𝑅# are the thermal resistances of hot/cold air convection, heat pipes, solder material, copper blocks, thermal interface material, and thermoelectric generator, respectively. The electric power produced by the TEG is calculated as follows: 𝑃#$ # = πœ‡ # 𝑄! (8) Where πœ‡ # is the conversion efficiency of thermoelectric generator. 214

5 4.2 Overall HPTEGs Thermal Resistance Equation If more than one number of HPTEG modules to be used, the total thermal resistance may be calculated as follows: 𝑅! = # 𝑅! (9) Where π‘Ž is the module thickness in x-direction and 𝑏 is the module wide. Fig. 4. A single module of heat pipe thermoelectric generator (HPTEG) and its equivalent thermal resistance, 𝑅! Fig. 5. The equivalent thermal resistance, 𝑅! 215

6 4.3 Thermoelectric Generator (TEG) Model An experiment to measure the thermal properties of thermoelectric generator (TEG) was conducted using forced convection cooling. This experiment was important to determine TEG thermal resistance, 𝑅# and TEG conversion efficiency, πœ‡ # as they are needed in the theoretical model. The thermoelectric generator conversion efficiency πœ‡ # is defined as the ratio of the generated electrical power 𝑃#$ # and the heat input into the module 𝑄! : πœ‡ # =!#$ #!!!!#$ # (1)!!!#$ # Where 𝑄! = π‘š# 𝐢! # 𝑇 is the heat removed from the cooled side of the TEG. In this experiment, an electric heater was used to supply heat to the hot side of TEG. The cold side was cooled by heat pipe as shown in Fig. 6. The mass flow rate of air in the cooling duct was controlled using DC fan. An electronic load acts as an external resistance was connected to the TEG to match the internal and external electric resistance of the TEG. Data such as temperature measurements, output voltage and current were recorded by the Agilent 3497A data logger. DC Fan Cold air thermocoupl e Temperatures line Hot air thermocoupl e Air flow Data Logger Fins Air Duct Heat Pipes Current line Voltage line TEG Electric heater Electronic load Fig. 6. The experimental set-up for measuring TEG properties Heat loads between 3-8W were applied onto an active surface of TEG (4mm X4mm area size). For each heat load, the external resistances were varied to obtain the maximum power output from a TEG. The maximum power point should occur when the internal resistance of the TEG is equal to the external load. In this case, the measured internal resistance was approximately between 2.8 to 3.4 Ω. Fig. 7 shows experimental results for a single TEG and the highest power output obtained was 1.12W when 8W of the heat was supplied. The thermal resistance of the 𝑅#, was 1.5 C/W and was calculated based on the temperature difference 216

7 between thermocouples installed on the hot and cold sides. Fig. 8 shows the TEG conversion efficiency versus the TEG temperature gradient. The efficiency varies approximately linear with the rise of driving temperature difference. The highest efficiency recorded in the experiment was around 2% when the temperature difference was around 85 C. Thus, the graph reveals a correlation between conversion efficiency and temperature gradient across TEG. Power,P (W) Electrical resistance, Ω (Ohms) 3W 4W 6W 8W Fig. 7.

Conversion efficiency versus temperature different of TEG. 5. Result and Discussion of the Theoretical Model. All the input parameters can easily be modified in the theoretical model. This model allows simulation of various cases by varying the input parameters. The main input parameters in this model are the number of thermoelectric generator and heat pipe, air flow properties and heat input. The important output variables are the temperatures at hot and cold side of TEG, the electric output power and the heat recovery rate. Fig. 9 shows the rate of total heat transfer versus the air flow speed. The air speed was varied between.5 to 2 m/s for the duct size of 17mm (height) X 16mm (wide). The amount of heat transfer has reduced dramatically with an increase of air flow speed. An air speed at a slower rate such as.5 m/s has produced better heat transfer rate than a higher rate like 5 m/s. 217

8 For the number of HPTEG module used, more heat can transfer if more rows of HPTEG are added. For example, the amount of heat transfer rises steadily with the number of rows such as W for 2 rows, W for 4 rows, W for 8 rows and W for 1 rows and at the air speed of.5 m/s which is minimum limiting value to prevent TEG failure due to overheating. The numbers of rows of HPTEG are limited to 8 in this study because of the cost and the size of laboratory test rig. Heat Transfer Rate, Qm (W) rows 4 rows 8 rows 1 rows Air velocity, v (m/s) Fig. 9. Effect of adding more rows of HPTEG When 8 rows of HPTEG were selected, the maximum hot side temperature was predicted to be 251 C (.5 m/s), and the cold side temperature was at 195 C with a temperature gradient of C across the TEG. It is seen from the model that the temperature gradient gradually decreases with increase in the air speed. These performance predictions allow us to monitor the hot side temperature of TEG not to exceed it limit that can cause damage to thermoelectric cell.

9 Fig. 1 shows the maximum power output is 26.2W from 8 rows of HPTEG. This occurred when W of heat flows across the modules. As a result, the energy conversion efficiency is around 1.35%. The power has significantly dropped between.6 m/s to 1 m/s and further steadily decreased with the faster air velocity. 6. Conclusion The study proposes a new concept of fully passive and stand-alone cogeneration system based on the use of combined heat pipe and thermoelectric generator (HPTEG). For that purpose, a theoretical model was developed to predict a preliminary performance of such system before commencing to the actual laboratory work. An experiment to study the thermal performance characteristics of thermoelectric generator (TEG) was also conducted. The theoretical simulation has suggested that 8 modules of HPTEG could recover more than 1.9kW thermal energy of heat input. Simultaneously, it also could produce about 27W of electric power. This research reveals a new method for recovering waste heat using heat pipes, at the same time produce electrical power using a passive device such as thermoelectric generators. 7.
