Abstract

The invention provides a heat exchange device which comprises a core body, the core body comprises a first hole channel, the heat exchange device further comprises a valve body, the valve body is provided with a first containing cavity, the heat exchange device further comprises a valve element assembly, the valve element assembly is provided with a throttling hole, the valve element assembly is partially located in the first containing cavity, and the heat exchange device further comprises a first filtering assembly. The first filtering assembly is also located in the first containing cavity and is in sealing fit with the corresponding wall part of the first containing cavity; or, the first filter assembly is located between the valve body and the core body, one surface defined and perpendicular to the axis of the first containing cavity is a projection surface, the projection of the wall part corresponding to the first containing cavity on the projection surface is located in the projection of the first filter assembly on the projection surface, and the first filter assembly is in sealing fit with the valve body and / or the core body; the first filtering assembly is close to the core body relative to the valve element assembly and comprises a first filtering net, and meshes of the first filtering net communicate with the throttling hole and the first hole channel. The core body is prevented from being blocked.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a heat exchange device. Background technique [0002] Electronic expansion valve is a commonly used component in refrigeration equipment to regulate fluid flow, generally located upstream of the evaporator. [0003] In a refrigeration device, the evaporator and the electronic expansion valve are integrated into a heat exchange device. During the use of the heat exchange device, impurities from the refrigerant or some impurities remaining during the processing and installation of the expansion valve will cause With the refrigerant flowing into the heat exchanger, the refrigerant flow path in the heat exchanger may be blocked. SUMMARY OF THE INVENTION [0004] An object of the present invention is to provide a heat exchange device that can prevent impurities from advancing into the core to block fluid passages. [0005] Provided is a heat exchange device, comprising a core body, th...
