Problems solved by technology

[0006] The advantages of using an independent temperature control system for each of the above-mentioned parts are that the system is flexible and easy to operate, but its energy utilization efficiency is low and it is not convenient for centralized management
For traditional cars, this will lead to an increase in fuel consumption and exhaust emissions, which will not save energy and aggravate environmental pollution
For electric vehicles, more importantly, it will lead to a shorter driving range

Abstract

The invention discloses an electric vehicle air-conditioning system using a capillary network radiation end. The electric vehicle air-conditioning system using a capillary network radiation end comprises a heat pump type refrigeration system, a battery box heat management system and a capillary network radiation end air-conditioning system, wherein the heat pump type refrigeration system comprises a heat pump type water chiller, a circulating water pump, a solenoid valve and the like; the battery box heat management system comprises a battery box, a first controller, a power battery pack, a microchannel cold plate and a temperature sensor; a temperature signal of the battery box is transmitted to the first controller, so that a control instruction is issued to a first solenoid valve and the heat pump type water chiller; the capillary network radiation end air-conditioning system comprises a second controller, a capillary network radiation end and a passenger compartment temperature sensor; and a temperature signal of a passenger compartment is transmitted to the second controller, so that a control instruction is issued to a second solenoid valve and an auxiliary electric heating system. According to the electric vehicle air-conditioning system using a capillary network radiation end disclosed by the invention, the same circulation loop is adopted, so that the heat management requirements of the battery box are met, and requirements for supplying cold for the passenger compartment in summer and supplying heat for the passenger compartment in winter are met.

Description

technical field [0001] The invention belongs to the technical field of air conditioners for electric vehicles, in particular to an air conditioner system for electric vehicles using capillary network radiation ends. Background technique [0002] In traditional cars, the parts that need temperature regulation mainly include the passenger compartment and engine; while in electric vehicles, the parts that need temperature regulation mainly include the passenger compartment, battery box, and electric motor. [0003] At present, most of the temperature regulation systems in the above parts are independent. In traditional cars, the temperature of the passenger compartment is controlled by the car's air conditioner; the engine uses a water-cooled system, and the cooling water cools down through the radiator at the front of the car. In electric vehicles, the temperature of the passenger compartment is cooled and heated by the vehicle air conditioning system; the motor adopts a wate...
