Meeting the increasing global demand for energy coupled with the depletion of fossil fuel sources has created breakthroughs in research on waste heat energy harvesting devices. By utilizing waste heat, energy consumption does not grow and is efficiently used instead. Harvesting energy from automobiles has promising outcomes for the application of thermoelectric generators (TEGs). Heavy duty diesel engines, pick-up trucks, sport bikes and model airplanes are involved in research attempting to do away with heavy batteries or alternators. For this study, a single cylinder, 100 cc Honda EX5 Dream, which is also known as ‘Kapcai’, was used to study the viability of installing TEGs for waste heat recovery in underbone of the motorcycle chassis. The natural convection passive cooling system of fin was used to dissipate heat for cold side of the TEGs to maintain temperature difference across TEGs of the motorcycle waste heat recovery system. Two currently commercially available TEG modules were used and were connected in series and parallel in order to obtain output power. Results for a single module of each of the two TEGs testing recorded a temperature gradient of 57.5 °C and 62.7 °C with open circuit voltage of 1.677 V and 1.704 V, respectively. The highest temperature difference and output voltage were recorded at 73.2 °C and 4.2 V in series arrangement for both the TEGs. In the same arrangement, the highest power output obtained was 551.0 mW. The outcomes from this field testing shows the applicability of waste heat recovery from the underbone chassis of a typical motorcycle in charging small portable devices such as smartphones or power banks for the rider of motorbike.

使用热电发电机收集摩托车废热能

满足日益增长的全球能源需求以及化石燃料资源的枯竭，在废热能源收集装置的研究方面取得了突破。通过利用废热，能源消耗不会增加，而是可以有效利用。从汽车中收集能量对于热电发电机（TEG）的应用具有可喜的成果。重型柴油发动机，轻型卡车，运动自行车和模型飞机参与了研究，试图消除重型电池或交流发电机。在这项研究中，使用了一个单缸100 cc本田EX5 Dream（也称为“ Kapcai”）来研究在摩托车底盘的下部安装TEG进行余热回收的可行性。鳍片的自然对流被动冷却系统用于散发TEG的冷侧热量，以保持摩托车废热回收系统的TEG之间的温差。使用了两个当前可商购的TEG模块，并将其串联和并联连接以获得输出功率。两个TEG测试中每个模块的单个模块的结果记录的温度梯度分别为57.5°C和62.7°C，开路电压分别为1.677 V和1.704V。对于两个TEG，最高温度差和输出电压在73.2°C和4.2 V串联下记录。在相同的布置中，获得的最高功率输出为551.0 mW。
