Abstract

The invention relates to an electric drive pump, which comprises a motor shell and an electric control plate. The electric control plate is arranged in an inner cavity of the motor shell. The electric drive pump further comprises a heat radiating assembly. The heat radiating assembly is fixedly connected with the motor shell, and comprises a heat-conducting plate and a first heat radiating assembly; the heat-conducting plate is arranged in the inner cavity of the motor shell; the first heat radiating assembly is arranged on the outer part of an inner cavity of an impeller cavity cover; the heat-conducting plate and the first heat radiating assembly are made of metal materials; the first heat radiating assembly comprises a metal plate and heat radiating fins; and the metal heat radiating fins are distributed on the surface of the metal plate. A heat radiating area can be favorably improved, heat produced by the electric control plate is taken away in time, and the service life and the control accuracy of the electric drive pump are favorably improved.

Description

[0001] 【Technical field】 [0002] The invention relates to an electrically driven pump, which is specifically applied to a heat cycle system. [0003] 【Background technique】 [0004] In recent decades, electric drive pumps have gradually replaced traditional mechanical pumps and are widely used in thermal cycle systems. The electric drive pump has the advantages of no electromagnetic interference, high efficiency and environmental protection, stepless speed regulation, etc., which can well meet the requirements of the market. [0005] The electric control board controls the operation of the electric drive pump. The electric control board generates more heat during the working process. Failure to dissipate heat in time will lead to premature damage of the electric control board and affect the control accuracy. [0006] Therefore, it is necessary to improve the existing technology to solve the above technical problems. [0007] 【Content of invention】 [0008] The object of the...
