Abstract

The invention provides an automobile exhaust waste heat recycling system applied in the technical field of automobile engines. A front end plate (35) is arranged at the position, close to an inlet cone end (33), between an outer layer shell (31) and an inner layer shell (32) of a heat exchanger (6) of the automobile exhaust waste heat recycling system; a rear end plate (36) is arranged at the position, close to an outlet cone end (34), between the outer layer shell (31) and the inner layer shell (32); a plurality of flat tubes (37) are inserted between the front end plate (35) and the rear endplate (36); fins (38) are inserted in each flat tube (37) separately; and a gap part is formed between each flat tube (37) and the fin (38) inserted in the flat tube (37). The automobile exhaust heatrecycling system can recover part of the heat from automobile exhaust when an automobile is cold-started, and then utilize the heat to heat a coolant in an automobile engine cooling system so as to quickly and reliably warm an engine and improve the thermal efficiency of the engine during cold-start.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and more specifically relates to a system for recovering and reusing waste heat from automobile exhaust. Background technique [0002] With the global energy situation becoming more and more tense, environmental protection becoming more and more urgent, and the number of cars in various countries in the world continues to rise, traditional fuel vehicles and hybrid vehicles are facing huge pressure on energy conservation and emission reduction. For traditional automobile engines, the water temperature in the engine water jacket is low during cold start. At this time, the lubrication effect of the various parts of the engine is poor, the friction force is large, and the thermal efficiency is low. At this time, the combustion in the cylinder is relatively insufficient, so The production and emission of harmful gases are relatively high. At present, there is no good way to improve the ther...
