New energy automobile cooling water pump

Abstract

The invention discloses a new energy automobile cooling water pump which mainly comprises a motor, a shell, a front cover and a bottom cover. The front cover is arranged on the top part of the shell;the bottom cover is arranged on the bottom part of the shell; the bottom part of the bottom cover is connected with the motor; a connecting shaft is arranged in the shell; the top part of the connecting shaft is connected with the bottom part in the front cover; the bottom part of the connecting shaft penetrates through the bottom cover so as to be connected with the motor; a first connector and asecond connector are formed in the front cover and are reducing types; the first connector is a water inlet; the second connector is a water outlet; a connecting frame is arranged on the bottom partof the motor and is fixedly connected with an automobile body; and an impeller is arranged on the connecting shaft. The new energy automobile cooling water pump provided by the invention is simple instructure, convenient to install and use, and capable of effectively improving the operation efficiency of the water pump, reducing the energy consumption at the same time, and meeting the requirements of environmental production and energy conservation.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a new energy vehicle cooling water pump. Background technique [0002] The power plant of new energy (gasoline-electric hybrid, pure electric) models mainly includes an engine (only for hybrid vehicles), a motor, an inverter and a motor controller. The cooling method of these power devices generally adopts water cooling, and how to provide cooling fluid circulation power for the cooling systems of other power devices except the engine has become an important issue. For many reasons, the cooling system of the power unit of the new energy vehicle cannot use the mechanical water pump used to drive the vehicle engine. Moreover, even if the hybrid vehicle is equipped with an engine, the cooling system of the power unit other than the engine cannot be cooled by the same cooling system as the engine. The coolant circulation circuit, so the engine water pump cannot be shared with th...
