Embodiment Construction

[0029] The present invention is described in detail below in conjunction with accompanying drawing:

[0030] The dual-circulation cooling system for engineering vehicles of the present invention is composed of a high-temperature circulation cooling system and a low-temperature circulation cooling system. The air first flows through the low-temperature radiator in the low-temperature circulating cooling system, and then flows through the high-temperature radiator in the high-temperature circulating cooling system to realize the heat exchange between each heat source of the vehicle and the cooling air.

[0031] The engineering vehicle dual-cycle cooling system of the present invention is composed of a high-temperature cycle cooling system and a low-temperature cycle cooling system.

[0032] refer to figure 1 , the high-temperature circulating cooling system is mainly composed of an engine 1, an engine water pump 2, an engine thermostat 3, a liquid-liquid radiator a4, and a high...

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.

Description

technical field [0001] The invention belongs to the technical field of vehicle cooling and heat dissipation, and relates to a dual-circulation cooling system for an engineering vehicle, which is suitable for a multi-heat source system of an engineering vehicle and an efficient heat dissipation mode required for large heat dissipation. Background technique [0002] Engineering vehicles must meet various functional requirements such as driving and operation. The vehicle system has many heat sources, such as the heat source of the engine water cooling system, the heat source of the engine pressurized air, the heat source of the vehicle transmission system, the heat source of the hydraulic system of the vehicle operating device, and the heat source of the engine fuel supply system. The heat source of the condenser of the air-conditioning system, etc., depends on the configuration of the host system, and the heat source of the vehicle is slightly different. The vehicle cooling sy...
