Dual cycle cooling system for engineering vehicle

Abstract

The invention belongs to the technical field of cooling of vehicles and relates to a dual cycle cooling system for an engineering vehicle. The problems that in the prior art, the heat dissipation efficiency is low, the structure size is large, and cooling energy consumption is large are solved. The dual cycle cooling system is composed of a high-temperature cycle cooling system and a low-temperature cycle cooling system. The high-temperature cycle cooling system is composed of an engine, an engine water pump, a liquid-liquid radiator a and a high-temperature radiator. High-temperature cycle cooling liquid sequentially flows through an inner cooling cavity of the engine and the liquid-liquid radiator a. The low-temperature cycle cooling system is composed of a low-temperature radiator, a low-temperature cycle pump, a water cooling intercooler and a liquid-liquid radiator c. After low-temperature cycle cooling liquid passes through the low-temperature radiator, the low-temperature cyclecooling liquid sequentially flows through the water cooling intercooler and the liquid-liquid radiator c. Cooling air firstly flows through the low-temperature radiator and then flows through the high-temperature radiator, and heat exchange between heat of the systems of the vehicle and air is achieved. By means of the dual cycle cooling system for the engineering vehicle, the structural size of the radiators is reduced, the cooling efficiency of the cooling air is improved, and energy consumption of the vehicle cooling system is reduced.
