AI Technical Summary

Technical Problem

The existing internal circulation cooling structure of electronic water pumps lacks a coolant drainage function, resulting in poor coolant circulation and an inability to effectively remove the heat generated by the electronic control components.

Method used

An internal circulation cooling structure is designed, comprising a support base, a housing assembly, a limiting assembly, a pipe groove, a water collection cover, a water collection pipe, a leak-proof pipe, and a water extraction pipe. The coolant is discharged under external power through the water collection cover and the water extraction pipe, and leakage is prevented by a snap-on leak-proof pipe.

Benefits of technology

It enables effective drainage of coolant, avoids leakage, improves cooling efficiency, and facilitates the repair and maintenance of the electric water pump.

Abstract

The utility model relates to the technical field of electronic water pumps, in particular to an internal circulation cooling structure of an electronic water pump, which comprises a support base, the top of the support base is movably connected with a shell component, the outer wall of the shell component is movably sleeved with a limiting component, and one side of the shell component is provided with a charging interface. A pipeline groove is formed in the top of the shell assembly, the inner wall of the pipeline groove is movably sleeved with a drainage assembly, and the bottom of the drainage assembly is movably sleeved with an electronic pump body. According to the device, a shell protection structure convenient to disassemble and assemble can be provided for the electronic water pump, so that parts of the electronic water pump can be rapidly maintained and replaced under the fault condition, and cooling liquid can be discharged in time by arranging the drainage assembly; therefore, the cooling liquid subjected to cooling operation can be sent out of the device so as to bring out heat, the cooling effect of the device is improved, and convenience and feasibility are provided for circulation of the cooling liquid.
