Medium filter for electric automobile heat management system convenient to replace

Abstract

The invention discloses a medium filter for an electric automobile heat management system convenient to replace. The medium filter comprises a base, wherein a precipitation cup is connected to the base in a threaded mode; a main channel is horizontally arranged in the base, the main channel is connected to a circulation pipeline of the electric automobile heat management system in series through amedium inlet and a medium outlet of the main channel, a filter element is clamped in the precipitation cup, an annular cavity is defined between the side wall of the filter element and the inner wallof the precipitation cup, and an inlet part of the main channel communicates with the annular cavity; the inner cavity of the filter element communicates with the outlet part of the main channel upwards; a precipitation cavity is defined by the bottom surface of the filter element and the inner wall of the precipitation cup below the filter element bottom surface, and the settling cavity is downwards connected with a sewage discharging structure; and an inlet cock valve is arranged on a valve seat of an inlet part of the main channel, and an outlet cock valve is arranged on a valve seat of anoutlet part. According to the medium filter, too much media can be prevented from flowing out when the filter element is replaced, the cost of supplementing liquid is reduced, and the maintenance workload of frequently supplementing the liquid medium is avoided. According to the medium filter, the sewage discharge and backwashing are integrated, so that the filter element is prevented from beingblocked.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a medium filter in a thermal management system of an electric vehicle. Background technique [0002] In recent years, due to the depletion of fossil energy and the increasing environmental pollution of people, there has been an upsurge in the development and application of new energy vehicles all over the world. New energy vehicles include electric vehicles, hydrogen fuel vehicles, solar vehicles, etc. Electric vehicles are a major aspect of new energy vehicles. [0003] my country's new energy vehicle market is developing rapidly. 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...

Problems solved by technology

The medium used in the thermal management system (pure water, a mixture of 50% pure water and 50% ethylene glycol or a mixture of 50% pure water and 50% propylene glycol) will inevitably be mixed with some impurities during transportation and storage. May cause poor cooling of the thermal management system or even damage other devices in the thermal management system

[0005] In order to ensure the stability and reliability of the thermal management system, it is very necessary to equip the thermal management system with a media filter that filters out impurities to ensure the cleanliness of the system. The applicant's patent 2017207568382 discloses a thermal filter suitable for electric vehicles. The media filter of the management system, but it is very inconvenient to replace the filter element and discharge the sewage. few cases
