Abstract

The invention relates to the technical field of heat management, and provides an integrated heat management system and method and an operation machine. The integrated heat management system comprises an air conditioning system, a motor heat exchange loop and a hydraulic cooling system; the motor heat exchange loop is in heat exchange connection with the air conditioning system and is suitable for auxiliary heating of the air conditioning system; the hydraulic cooling system is in heat exchange connection with the air conditioning system and is suitable for defrosting outdoor heat exchange equipment of the air conditioning system. According to the integrated heat management system and method and the operation machine, the motor waste heat can be used for assisting the air conditioning system in heating in the low-temperature environment, the heating efficiency of the air conditioning system in the low-temperature environment is improved, the utilization rate of the motor waste heat is also increased, and in addition, when the air conditioning system works, if outdoor heat exchange equipment is frosted, the air conditioning system can still work. Defrosting can be conducted through hydraulic waste heat in the hydraulic heat dissipation system, the heat exchange efficiency of the air conditioning system is guaranteed, the heating energy efficiency ratio of the air conditioning system in the low-temperature environment is increased, and the utilization rate of motor waste heat is also increased.

Description

technical field [0001] The present invention relates to the technical field of thermal management, and in particular, to an integrated thermal management system, method and working machine. Background technique [0002] At present, the market share of electric work machinery (such as electric loaders) is increasing year by year, and the advantages of zero emission, low noise, high efficiency and energy saving make it the development trend of future loaders. When the ambient temperature of the air-conditioning system installed in the work machine is low, simply using the air-conditioning system to heat the cab has many problems, such as high energy consumption, difficulty in meeting the heating demand, and frosting of the outdoor heat exchange equipment, so it cannot achieve a good system. thermal effect. However, the existing thermal management systems of electric working machines have problems such as low integration, high energy consumption and complex structure. SUMMAR...
