一种微通道换热器及带有该微通道换热器的脉管制冷机
摘要：
本发明公开了一种微通道换热器及带有该微通道换热器的脉管制冷机，属于低温制冷技术领域，本发明提供的微通道换热器包括壳体，壳体包含筒体，该筒体的两端由封板封闭，每块封板上均开设有若干扁管安装孔；两端的扁管安装孔之间密封连接有扁管，扁管分隔出若干微通道，所有扁管内的微通道作为换热器的第一介质通道；各扁管的外壁与筒体内壁之间的空间与筒体上的介质入口和介质出口连通作为换热器的第二介质通道。该微通道换热器的换热面积大，换热效率高，且结构简单。
摘要（英）：

The invention discloses a microchannel heat exchanger and a pulse tube refrigerator provided with the microchannel heat exchanger, and belongs to the technical field of low-temperature refrigerating. The microchannel heat exchanger provided by the invention comprises a shell. The shell comprises a barrel. The two ends of the barrel are sealed through sealing plates. Each sealing plate is provided with a plurality of flat tube mounting holes. Flat tubes are connected between the flat tube mounting holes in the two ends in a sealed mode. A plurality of microchannels are partitioned through the flat tubes. All the microchannels in the flat tubes are used as first medium channels of the heat exchanger. Spaces between the outer walls of all the flat tubes and the inner wall of the barrel communicate with a medium inlet and a medium outlet which are formed in the barrel to be used as second medium channels of the heat exchanger. The microchannel heat exchanger is large in heat exchange area, high in heat exchange efficiency and simple in structure.
