Novel liquid self-cooling circulating-type large-power brushless electronic water pump

Abstract

The invention discloses a novel liquid self-cooling circulating-type large-power brushless electronic water pump. The novel liquid self-cooling circulating-type large-power brushless electronic waterpump comprises a pump head, a waterproof chamber assembly and a motor case which are connected in sequence; a water inlet pipe and a water outlet pipe are arranged on the pump head, an impeller assembly is arranged in the pump head, and a stator assembly and a rotor assembly are arranged in the motor case; a bearing body is arranged at the end, away from the waterproof chamber assembly, of the motor case, and a bearing is arranged on the bearing body; a controller is mounted on the outer side of the bearing body and sealed through a rear cover, and the position between the bearing body and thecontroller is filled with a heat-conducting material; a cooling chamber is formed in the inner side of the bearing body; a water inlet channel of the cooling chamber communicates with the water outlet pipe, and a throttling valve is arranged between the water inlet channel and the water outlet pipe; and a water outlet channel of the cooling chamber communicates with the water inlet pipe. The problem that thermal protection of the controller is caused by the excessively-large temperature rise, and consequently the water pump stops can be effectively avoided; and the flow of cooling liquid canbe controlled through the throttling valve, and the conveying efficiency of the water pump is prevented from being influenced.

Description

technical field [0001] The invention belongs to the field of electronic water pumps, and in particular relates to a novel liquid self-cooling circulation type high-power brushless electronic water pump. Background technique [0002] The brushless electronic water pump is a new type of water pump that uses a brushless motor as a power device, completely realizes electronicization from control to drive, and completely controls liquid transmission with an electronic integrated system, thereby realizing the adjustability and accuracy of liquid transmission. [0003] The controller of a high-power water pump generates a lot of heat, the temperature rises quickly, and is easy to overheat. However, the heat of the existing high-power electronic water pump controller can only conduct heat through the parts in contact with it, and finally transfer heat through natural cooling, and the heat dissipation is too slow. , often lead to high temperature rise of the pump, which affects the s...
