Medium filter suitable for electric car heat management system

Abstract

A medium filter suitable for an electric car heat management system comprises an upper shell, a lower shell and a filtering core. The upper shell and the lower shell are connected onto a cyclic pipeline, for circulating of media, in the heat management system. The filtering core comprises a filtering cylinder mounted in the lower shell, a large press ring, a small press ring, a cover nut, a bolt and magnetic steel. The filtering cylinder is defined by a circumferential filtering layer and a bottom filtering layer, an annular gap is formed between the filtering cylinder and the lower shell, and the circumferential filtering layer is fixedly connected with the outlet end of the upper shell. The inner side wall of the circumferential filtering layer is fixedly connected with the small press ring in the circumferential direction, the outer side wall of the circumferential filtering layer is fixedly connected with the large press ring in the circumferential direction, and the bottom filtering layer is fixedly connected between cross-shaped rib plates of the large press ring and the small press ring. The magnetic steel is fixedly connected with the cross-shaped intersection position of the small press ring and the large press ring, and the circumferential filtering layer and the bottom filtering layer comprise inner-layer filtering nets for filtering and outer-layer filtering nets for supporting correspondingly. According to the medium filter suitable for the electric car heat management system, impurities of the media in the cooling system can be filtered, and the cleanliness of the media is improved.

Description

technical field [0001] The invention belongs to the field of thermal management systems of electric vehicles, and relates to a medium filter of the thermal management system of electric vehicles. Background technique [0002] Due to the needs of environmental protection and energy saving, my country's new energy vehicle market is developing rapidly. Electric vehicles are an important category of new energy vehicles. With the continuous advancement of power battery technology, electric vehicles have also achieved rapid development. Electric vehicles need to control and adjust the internal temperature of the vehicle and the temperature of the working environment of the components through the thermal management system to ensure that the components can work normally and provide a comfortable riding environment for the occupants. [0003] The thermal management system of electric vehicles generally includes HVAC systems, battery thermal management systems and motor thermal manage...
