Problems solved by technology

[0002] At present, the power conversion efficiency of automobile engines is only about 40%, and the remaining 60% of the energy is dissipated into the air in the form of heat, causing huge energy waste. Therefore, people often connect the waste heat of automobile exhaust pipes through pipes. Put it on the radiator in the car and use the remaining heat for heating, which is economical and convenient
But this part of energy is wasted when there is no need for heating

Embodiment 1

[0017] according to figure 1 As shown, the main body 2 of the power generation device is a tubular structure, the wall of which is the main body 2 of the thermoelectric converter, the middle part is the exhaust pipeline channel 3, the outer layer is provided with a low-temperature cooling end 1, and the inner wall is provided with a high-temperature heat-absorbing end 4. The cooling end 1 and the high-temperature heat-absorbing end 4 are both designed as fin-shaped structures, and the low-temperature cooling end 1 of the thermoelectric converter is cooled by the vehicle body and air, and the current output terminal 5 is respectively connected to the low-temperature cooling end 1 and the high-temperature heat-absorbing end 4 .

Embodiment 2

[0019] refer to image 3 , the low-temperature cooling end 1 of the utility model can also be designed as a water-cooled structure, and a cooling water channel 6 is provided between the thermoelectric converter main body 2 and the low-temperature cooling end 1, which can be connected with the water circulation cooling system of the engine, and the low-temperature The end can be directly cooled with water, which is more convenient and practical.

Embodiment 3

[0021] The above materials are made into thermoelectric conversion devices of different shapes such as circular or elliptical according to the shape of the vehicle and ship exhaust pipe (see figure 2 ), installed on the vehicle and ship can be used. The output power can be directly charged into the battery or used by other electrical appliances.

Abstract

This invention discloses a method for generation with the waste heat of the engine vent-pipe and a device, in which, the device is a pipe, the pipe wall is the principle part of the converter, the middle is the channel of the pipe, the outer layer is set with a cooling end, the internal wall is set with heat absorption end, the current output terminals are connected with the both ends, the high temperature absorption end is put into the vent-pipe directly to absorb heat fully and the car and air are used to cool down the low temperature end of the converter to form a temperature difference by high temperature and natural air to finish the generation function.

Description

technical field [0001] The invention discloses a method for power generation with exhaust pipe waste heat of an engine, and also provides a power generation device suitable for the method, and belongs to the technical field of waste heat reuse and thermoelectric conversion of engines such as vehicles and ships. Background technique [0002] At present, the power conversion efficiency of automobile engines is only about 40%, and the remaining 60% of the energy is dissipated into the air in the form of heat, causing huge energy waste. Therefore, people often connect the waste heat of automobile exhaust pipes through pipes. To the radiator in the compartment, using the remaining heat for heating, which is economical and convenient. But this part of energy is wasted in vain when there is no need for heating. If we utilize this part of energy to heat in winter and cool in summer, a lot of energy will be saved, which will definitely bring considerable economic benefits and good s...
