Description

technical field [0001] The invention relates to a power generating device, in particular to a power generating device which utilizes natural wind and heat generated by the vehicle itself to generate direct current through a thermoelectric power generation sheet assembly. It belongs to the technology of energy recovery and regeneration. Background technique [0002] With the development of the economy, the penetration rate and utilization rate of automobiles are getting higher and higher. The automobiles powered by gasoline engines and diesel engines consume more and more oil and cause more and more serious pollution to the environment. In order to reduce the dependence and consumption of oil and protect the environment, more and more attention has been paid to the research and development of new energy sources. Among them, the waste gas (up to 600°C) generated by vehicles such as automobiles and trains, and the hot air in the cabin (which is also several times higher than th...

Problems solved by technology

[0003] CN201332370Y discloses a device for thermoelectric power generation using the exhaust pipe exhaust gas of a vehicle. The thermoelectric power generation sheet, heat sink, and heat insulation section of the device are closely matched with the square exhaust tube to form a whole. The deficiency of the device is that the exhaust pipe is produced Complex processing, increased weight and cost, inconvenient installation, maintenance and repair, and when the exhaust pipe is replaced, the thermoelectric power generation system needs to be replaced at the same time, and the operating cost is high, so the actual utilization rate is not high

[0004] CN200997576Y discloses another device for thermoelectric power generation using the exhaust temperature of the exhaust pipe of a vehicle. The device directly lays an arc-shaped thermoelectric power generation sheet on the outer wall of the exhaust pipe. It has high production and installation requirements, poor stability, and low temperature The surface heat dissipation performance is poor, and the power generation efficiency is not high in actual use

[0005] CN200997575Y discloses a device that utilizes the water temperature of the water tank of a vehicle to realize thermoelectric power generation. The device is to directly install a thermoelectric power generation sheet on the windward surface of the water tank. The natural wind cooling function when the vehicle is running, the heat dissipation is not smooth, the water temperature in the water tank rises rapidly, resulting in the reduction of the cooling function of the water tank, and the cooling fan is in working condition for a long time

The fan is in the working state for a long time, otherwise it will lead to an increase in power consumption
