Cooling system used for electric power apparatus and its control method

Abstract

A cooling system for electric devices comprises a water tank (6), a water pump (1), at least one temperature sensor (15) and a controller (16), and the water tank (6) is provided with a liquid outlet and a liquid inlet, wherein the cooling system further comprises an external environmental temperature sensor (13) which is electrically connected with an input end of the controller (16) to detect temperature of the external environment, the controller (16) controls the rotary speed of the water pump (1) through the temperature values detected by the external environmental temperature sensor (13) and at least one temperature sensor (15). Further, the controller (16) can realize real-time monitoring for the overall cooling system and can perform self-adaptive adjustment on working state of the cooling system according the external environment temperature in any situation, thereby significantly reducing energy consumption in the cooling system. Besides, the invention further provides a control method of the cooling system for electric devices.

Description

technical field [0001] The present invention relates to a cooling system and a control method thereof, more particularly, to a cooling system and a control method thereof for cooling an electric device. Background technique [0002] The cooling system is an indispensable part of the power device. For example, in a vehicle, the cooling system is used to adjust the temperature of the vehicle's engine, motor, AC-DC converter and other components to prevent the components from overheating, thereby ensuring the reliability and reliability of the vehicle. safety. [0003] Existing cooling systems such as the automobile cooling system for cooling automobile engines and automobile wheels in CN2649395Y propose to control the operation of cooling components by temperature. This cooling system includes at least one temperature sensing device, water tank, water pump, fan and other cooling components and a controller, wherein the temperature sensing device is used to detect the temperat...
