Engine-cooling system

Abstract

The invention relates to an engine-cooling system comprising a radiation branch and a heat preservation branch. The heat preservation branch comprises a heat preservation water tank, a bidirectional electric water pump, a pumping electromagnetic valve, an affusion electromagnetic valve, a pumping pipe, an affusion pipe, a backwater aeration pipe, a water quantity display, a water quantity displaysensor, a central controller, and the like, can preserve the heat of cooling liquid preserved in the heat preservation water tank when water in an engine reaches a normal temperature and full draws the high-temperature cooling liquid in the engine to the heat preservation water tank for preserving heat when the engine stops working so that the high-temperature cooling liquid in the heat preservation water tank preheats the engine when the engine is started up next time. The cooling system enables the cold-startup engine in an ideal temperature without external energy, effectively solves the problems of startup difficulties caused by the lower temperature of the engine, severe emission pollution, fuel waste, severe part abrasion, and the like and avoids causing energy waste during using the external energy for preheating.

Description

Technical field [0001] The invention relates to an engine cooling system, in particular to an engine cooling system capable of providing intelligent heat storage, heat preservation and preheating functions. Background technique [0002] At present, the structure of the known engine cooling system is made up of parts such as cooling water tank, fan, water pump, water jacket, thermostat and connecting pipeline. Its working principle is as follows: the water pump is directly driven by the crankshaft. When the engine starts to work, the water pump starts to work, and the coolant starts to circulate accordingly. When the temperature of the engine is low and does not need to be cooled, the thermostat controls the small circulation of the coolant through the bypass pipe to reduce heat dissipation; when the engine temperature rises and needs to be cooled, the thermostat controls the coolant to dissipate heat The large circulation of the water tank enhances heat dissipation.

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the adverse effects caused by the drop of engine temperature caused by the inability of the existing engine cooling system to stop heat dissipation, the present invention provides an engine cooling system, which can not only selectively perform heat dissipation and cooling according to the temperature of the engine, but also It can also keep the coolant warm and store heat, so that most of the heat of the engine can be retained, basically realizing the expected purpose of stopping the cooling system from dissipating heat.
