Waste heat power generating system used in cooperation with automobile engine

Abstract

The invention relates to a waste heat power generating system used in cooperation with an automobile engine. The waste heat power generating system mainly comprises the automobile engine, a cooling circulating power generation system connected with the engine, and an energy storage battery for collecting electric energy generated by the power generation system. The cooling circulating power generation system comprises a circulating pipe connected with the engine and forming a cooling liquid circulating circuit, and an electric generator connected with a power conversion device. A drainage pump, a check valve and a liquid storage tank for storing cooling liquid are arranged in the circuit of the circulating pipeline. Meanwhile, a temperature difference power generating device and a steam power generating device are arranged. By combining steam power generating and temperature difference power generating, the waste heat utilization rate is further increased; more electric energy can be produced compared with a frequently-used cooling system under the same conditions; in addition, according to the technology, only peripheral parts of the engine cooling system are refitted, refitting degree is not high, and market adaptability is high.

Description

technical field [0001] The present invention relates to a thermoelectric conversion system, and more particularly, to a power generation system utilizing waste heat of an automobile engine. Background technique [0002] The fuel heat utilization rate of the internal combustion engine of the current automobile is only 20-40%, and the rest is released into the air in the form of heat, resulting in a very low fuel utilization rate. At present, the heat energy is mainly cooled by cooling water and cooling fans to keep the engine at normal operating temperature. However, the heat energy in this process has not been utilized, and additional electric energy is needed to drive the cooling fan for cooling. The prior art also discloses related technologies for power generation with engine waste heat, but the utilization rate is not high. In addition, due to the use of engine waste heat, the structure of the engine cooling system needs to be modified to a certain extent, and safety i...
