Temperature difference power generation device of bus air exhaust pipe

Abstract

Provided is a temperature difference power generation device of a bus air exhaust pipe. A cooling water loop consists of a cooling pipeline and a heat absorbing copper pipe. Two water pumps are installed in the cooling water loop. An arc-shaped groove for absorbing residual heat of an automobile exhaust gas pipe is used as a hot end. A metal plate for absorbing cold quantity of the cooling loop is used as a cold end. A temperature difference power generation sheet is pressed between the hot end and the cold end. The heat absorbing cooper pipe is arranged on the base face of the metal plate. Impeller shafts of the water pumps stretch out of pump bodies and are installed on a driving box body. A double-faced gear for receiving automobile vibration energy is engaged to left gears and right gears. The left gears are installed on a fixed shaft through a bearing. One of the right gears is installed on the impeller shaft of one of the water pumps through a one-way bearing. The other right gear is installed on the impeller shaft of the other water pump through another one-way gear. The driving directions of the one-way bearings are opposite. According to the invention, the automobile vibration energy is used for providing driving force for impellers of the water pumps; the residual heat of automobile exhaust gas is converted into electric energy; and the power generation device is characterized in that the power generation device is high in utilization rate, free from pollution and commonly suitable for all automobiles.

Description

technical field [0001] The invention relates to an automobile tail gas waste heat power generation device, in particular to a temperature difference power generation device at the bottom of a bus exhaust pipe. Background technique [0002] With the rapid development of social economy, buses are becoming more and more popular. It not only relieves the traffic pressure in the city, but also greatly facilitates people's travel. It is an indispensable part of daily life. But at the same time, the heat generated by the exhaust pipe of the bus during operation seriously threatens the normal operation of the engine. At present, passive cooling methods such as cooling holes are mainly used for cooling in the market, and there are problems such as slow cooling and uneven cooling. Many disadvantages. In fact, the waste heat generated by the exhaust pipe is a kind of energy. If it can be collected and used, it can not only protect the environment, but also save resources. It can be sa...
