Micro-channel condenser used for refrigerator

The invention relates to the technical field of condensers, in particular to a condenser which is installed on a side plate or a back plate of a box body of a refrigerator and adopts a micro-channel parallel-flow heat exchange tube. The invention solves the problems of poor heat exchange capability, high manufacturing difficulty of the process of a product, too much filling quantity of a cooling medium and high cost of the condenser of the traditional refrigerator. The condenser comprises a fixed plate, a micro-channel tube, a refrigerant inlet tube and a refrigerant outlet tube, wherein the micro-channel tube is fixed on the fixed plate, the refrigerant inlet tube and the refrigerant outlet tube are arranged at both ends of the micro-channel tube, the micro-channel tube is bent into a single integral micro-channel tube with a U-shaped structure, the refrigerant inlet tube and the refrigerant outlet tube are connected with the inlet/outlet end of the micro-channel tube by a braze welding process, and the U-shaped micro-channel tube which is provided with the refrigerant inlet tube and the refrigerant outlet tube and has the single integral structure is tightly fixed in a groove arranged on the surface of the fixed plate. The invention has compact structure, simple process, low cost and no pollution.
