Abstract

The invention provides a micro-channel heat exchange panel suitable for phase-change heat exchange and a heat exchanger. The micro-channel heat exchange panel suitable for phase-change heat exchange comprises a plate body and a plurality of heat exchange channels arranged on the plate body, each heat exchange channel comprises an inlet section, a preheating section, an evaporation section, an overheating section and an outlet section, the inlet section, the preheating section, the evaporation section, the overheating section and the outlet section of each heat exchange channel are connected in sequence, each evaporation section comprises a first separation section and a second evaporation section which are connected in sequence, each first separation section is used for performing gas-liquid separation on flowing fluid, and each second evaporation section is used for completely evaporating the liquid-phase fluid after gas-liquid separation. According to the micro-channel heat exchange panel, the advantages that an original micro-channel heat exchange panel is large in heat exchange specific surface area and high in heat exchange efficiency can be guaranteed, meanwhile, the micro-channel heat exchange panel can be suitable for fluid heat exchange with the phase change process, and automatic separation of gas and liquid phases is achieved in the evaporation process.

Description

Technical field: [0001] The invention relates to the technical field of heat exchange, in particular to a microchannel heat exchange panel and a heat exchanger suitable for phase conversion heat. Background technique: [0002] In the field of heat exchange technology, the current microchannel heat exchanger is a new type of high-efficiency heat exchanger composed of a heat exchange core, a head, a connecting pipe, and a flange. It has high compactness, small size, and structural strength. High efficiency, high heat exchanger efficiency, high temperature and pressure bearing capacity, heat exchange channels can be designed and so on. Microchannel heat exchangers were first used in aerospace and aviation fields to cool part of the surface of aircraft or engines. However, with the maturity of processing technology, microchannel heat exchangers also have great application prospects in the field of civil energy saving. Therefore, microchannel heat exchangers Heat exchangers are ...
