Electric automobile heating system with heat absorber

Abstract

The invention discloses an electric automobile heating system with a heat absorber. The electric automobile heating system comprises an outer condenser, an evaporator, a compressor and an inner condenser, wherein the outer condenser, the evaporator, the compressor and the inner condenser are connected in turn, and the inner condenser is connected with the outer condenser; the electric automobile heating system further comprises the heat absorber; one end of the heat absorber is connected with the outer condenser; the other end of the heat absorber is connected with the evaporator and the compressor; and the third end of the heat absorber is connected with a water cooling system which is installed on a power control device of an electric car. With the adoption of the electric automobile heating system with the heat absorber, the low-temperature heat sources on a motor, a PCU and an FCE on the electric car are collected through arranging the heat absorber in the current electric automobile heating system so as to heat the electric car. The electric automobile heating system is simple in structure, and can be conveniently operated; and with the adoption of the electric automobile heating system, the energy consumption of the electric car is greatly reduced, the heating efficiency is improved, and the pollution of the environment is prevented.

Description

technical field [0001] The invention relates to a heating system for an electric vehicle, in particular to a heating system for an electric vehicle with a heat absorber. Background technique [0002] At present, the winter compartment heating technology for motor vehicles, especially electric vehicles, has become a technology that the automobile manufacturing industry is more concerned about. In traditional electric vehicle heating systems, some use the heat of vehicle exhaust to heat the car compartment, such as the patent application "Automotive Waste Heat Collector" with Chinese Patent No. CN90224135.4. low; some use the hot water of the engine or the heat formed by the coolant for heating, but this heating system not only wastes energy, but also produces hot air that is too dry and affects the comfort in the compartment; in addition, there is another car heating system that uses The heat released by PTC electric heating is used for heating. Due to the large resistan...

Problems solved by technology

In traditional electric vehicle heating systems, some use the heat of vehicle exhaust to heat the car compartment, such as the patent application "Automotive Waste Heat Collector" with Chinese Patent No. CN90224135.4. low; some use the hot water of the engine or the heat formed by the coolant for heating, but this heating system not only wastes energy, but also produces hot air that is too dry and affects the comfort in the compartment; in addition, there is another car heating system that uses The heat released by PTC electric heating is used for heating. Due to the large resistance value of PTC, it consumes a lot of electric energy, which not only affects the driving range of the car, but also has a low heating efficiency, which is less than 1

Therefore, a CO 2 The electric vehicle heating system with HFC-134a heat pump cycle came into being, which canceled the traditional hot water heating cycle and PTC heater, but did not apply the waste heat generated by the electric energy loss of the electric vehicle itself, resulting in relatively low heating efficiency. Low

[0003] As far as the electric vehicle itself is concerned, the motor, power control unit (PCU) or FCE on it all generate a certain amount of heat energy. This part of the low-temperature heat source is not used in the heating of the electric vehicle itself, causing energy loss to a certain extent. waste
