Embodiment 1

[0022] This embodiment discloses a novel muffler thermoelectric power generation device, please refer to figure 1 and figure 2 shown.

[0023] The muffler thermoelectric power generation device includes a muffler, a thermoelectric power generation module, and a cooling cycle system.

[0024] The muffler 1 includes an air source inlet 11, an air source outlet 12, an air source passage connecting the air source inlet 11 and the air source outlet 12, and the air source passage includes several main air passages 13 arranged side by side and connecting adjacent The connecting air channel 14 of the two main air channels 13 . In order to extend the overall length of the gas source passage in a limited space, the three continuous main air passages 13 and the connecting air passage 14 connecting the three main air passages 13 form an "S" curved shape. When there are more than three main air passages 13, they will continue to be bent and formed in an "S" curved manner. At the same ...

Embodiment 2

[0030] The present invention provides an automobile comprising the above-mentioned muffler thermoelectric power generation device. That is, in the second embodiment, the application of the muffler thermoelectric power generation device provided in the first embodiment to automobiles is also a main application of the first embodiment. The air source inlet of the muffler is connected to the exhaust gas discharge pipe of the automobile, and the automobile exhaust gas enters the muffler through the air source inlet. The bath can also be part of the cooling system of the car interior.

Abstract

The invention relates to a novel muffler thermoelectric power generation device and an automobile, The muffler thermoelectric power generation device comprises a muffler base, a thermoelectric power generation sheet and a cooling circulation system, wherein the cold end of the thermoelectric power generation module is in contact with the cooling circulation system, and the hot end is in contact with the outer wall of the muffler housing; and the circulation system is provided with a cooling circulation main system, a cooling circulation auxiliary system, a common solution pool and a synchronous pump. The invention improves the power generation efficiency and achieves the purpose of improving the energy utilization rate through the arrangement of the thermoelectric power generating pieces,the improvement of the structure of the cooling cycle system and the use of a novel working medium.

Description

technical field [0001] The muffler thermoelectric power generation device disclosed by the invention belongs to the technical field of thermoelectric power generation. [0002] The automobile disclosed by the invention belongs to the field of automobile tail gas treatment. Background technique [0003] Studies have shown that automobile engines use only 38.5% of the heat energy generated by fuel combustion as the indicated power output, but 33% of the heat energy is discharged into the atmosphere along with the exhaust gas. Therefore, if an environmentally friendly and practical energy recovery strategy can be proposed to recover the energy taken away by vehicle exhaust, it will certainly improve the utilization rate of vehicle fuel heat energy, thereby improving the overall performance of the vehicle. The emergence of the automobile exhaust temperature difference power generation system is a device developed to realize the recovery of waste heat energy of automobile exhaus...
