Automobile cooling liquid waste heat recycling device

Abstract

The invention discloses an automobile cooling liquid waste heat recycling device. The automobile cooling liquid waste heat recycling device comprises a liquid storage tank, a temperature difference power generation module, a heat dissipation device and a thermal insulation cushion. The liquid storage tank is connected with an engine cooling water way in series through a water inlet hole and a water outlet hole. Fin plates used for collecting heat of engine cooling liquid are arranged in the liquid storage tank. The heat dissipation device comprises main heat dissipation pieces and branch heat dissipation pieces, wherein the upper surfaces of the main heat dissipation pieces are matched with the lower surface of the liquid storage tank. The temperature difference power generation module is arranged between the lower surface of the liquid storage tank and the upper surfaces of the main heat dissipation pieces. The temperature difference power generation principle is adopted for the device, heat brought away by the engine cooling liquid is recycled by designing a cold source and hot source collection device and the power generation module, the heat is converted into electric energy to be used by electricity consumption devices on an automobile, and therefore energy is saved. The automobile cooling liquid waste heat recycling device is high in structural design flexibility, can be designed for different automobile types in a customized mode and can effectively recycle energy.

Description

technical field [0001] The invention belongs to the field of energy utilization and environmental protection, in particular to a cooling liquid waste heat recovery and utilization device used in automobiles. Background technique [0002] In recent years, with the vigorous development of my country's automobile industry, more and more vehicles are kept. However, during the operation of the automobile engine, the exhaust gas and the coolant take away nearly 60% of the heat of the engine. At present, this heat of the automobile engine has not been recycled, resulting in a large degree of energy waste. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the object of the present invention is to provide a device for recycling waste heat of automobile coolant, which uses the principle of thermoelectric power generation, and recovers the engine coolant and takes it away by designing a cold source and heat source collection device an...
