Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicles, and more specifically, relates to a thermal management device for an electric compressor for an R290 high-efficiency new energy vehicle. Background Art

[0002] New energy vehicles need to use electric compressors to control the temperature of the heat generated by the power. Existing electric compressor refrigeration generally uses R290 natural refrigerant. The heat generated by the electric compressor is transferred to the inside of the thermal management device. The cooling plate on the thermal management device controls the temperature to reduce greenhouse gas emissions.

[0003] According to CN201911020631.9, the present invention discloses a thermal management system for an electric vehicle, characterized in that it includes an expansion tank 1 and an expansion tank 2, wherein the expansion tank 1 forms a circuit with a heat exchanger 3 and electric vehicle components; the expansion tank 2 forms a circuit with a heat exchanger 2 and a battery pack; the heat exchanger 3 is connected to a three-way valve 1 through a throttle valve 1, the heat exchanger 3 is connected to a gas-liquid separator and an electric compressor, and the electric compressor is connected to the three-way valve 1 through the heat exchanger 1; the three-way valve 1 is connected to the throttle valve 2 and the throttle valve 3 respectively, the throttle valve 3 is connected to the gas-liquid separator through the heat exchanger 4, and the throttle valve 2 is connected to the gas-liquid separator through the heat exchanger 2. The thermal management system of the present invention has a simple process. While ensuring the normal operation of on-board equipment such as the battery pack and the drive motor, it not only prevents the off-board heat exchanger from frosting when the ambient temperature is low, but also fully utilizes the heat emitted by the on-board equipment, thereby meeting the thermal comfort requirements of the driver and passengers and effectively extending the cruising range of the electric vehicle.

[0004] Based on the above, the existing thermal management equipment is generally a rectangular integrated valve body structure. The integrated valve body structure and the electric compressor are connected by pipes to form a whole. Since the integrated valve body and the electric compressor are mostly electronic components and control elements, the thermal management equipment is easily bumped during transportation and handling. When the thermal management equipment collides with electronic components or control elements, it is easy to be damaged. Utility Model Content
