A multi-medium heat exchanger for new energy vehicle battery

Abstract

The application relates to the technical field of heat exchange equipment, and discloses a multi-medium heat exchanger for new energy automobile batteries, which comprises heat exchange pipes and heat dissipation assemblies on the two sides of the heat exchange pipes, the front end of the heat dissipation assembly is provided with a quick butt joint mechanism composed of a plug-in ring, a connecting ring, a spring and a clamping plate, elastic self-locking of pipelines can be realized, and vibration-induced falling off can be prevented; a screening cylinder with holes in the outer wall is arranged in the fixed cylinder and is filled with ordinary silica gel or molecular sieve, which is used for intercepting large-particle impurities in the medium and deeply adsorbing moisture, and can eradicate the hidden troubles of system dirt blockage and ice blockage; in addition, an anti-frosting auxiliary heating structure is integrated on the upper side of the equipment, which comprises a ceramic heating core body, a heat conduction gasket and a heat conduction fin, a mechanical pressing force downward is applied through the locking of the cover plate and the bolts, the interlayer assembly gap is eliminated, and the contact thermal resistance is reduced. The application effectively improves the pipeline assembly efficiency and operation stability, and obviously enhances the battery thermal management and active anti-icing and anti-frosting capability of the vehicle under extremely cold working conditions.
