The invention discloses a microchannel plate type
evaporator. The microchannel plate type
evaporator comprises an aluminum flat tube, the flat surface of an aluminum flat tube body is bonded with an aluminum plate, in the
machining process, in order to prevent the situation that darts occur to the aluminum flat tube, then a
refrigerant cannot flow, aluminum circular tubes are preset in an inner arc around which the flat tube overturns, the two preset aluminum circular tubes are pulled to be away from each other by a distance, one end of the aluminum flat tube is wound around one preset aluminum circular tube, and then the aluminum flat tube turned over by 360 degrees towards the lower portion of the other aluminum circular tube to be bent back and forth; after the aluminum flat tube body is formed, the preset aluminum circular tubes are drawn out from the two ends, an inlet tube is welded to the head end of the aluminum flat tube, the outlet tube is welded to the
tail end of the aluminum flat tube, then the aluminum flat tube is bonded with the aluminum plate through a heat conduction
adhesive film, and a microchannel plate type
evaporator is formed; and the distance between the two preset aluminum circular tubes is based on the width of the aluminum plate. According to the scheme, the microchannel flat tube is adopted in a
refrigerant channel, so that the thickness of a product is thin, and the space is saved; and the contact area between the microchannel flat tube and the aluminum plate is large, so that the flat tube and the aluminum plate are firmly bonded and are not prone to glue failure, and the heat exchange efficiency is high.
