External integrated oil cooler

The utility model relates to an external integrated oil cooler which comprises a refrigerating machine oil inlet/outlet, a cooling liquid inlet/outlet, a cooling cavity, a heat exchange group plate, asupporting back plate, a hoop and a base plate, and the oil inlet/outlet is communicated with a refrigerating oil circulation loop of a refrigerating machine; the cooling liquid inlet and outlet is connected with a cooling liquid circulation loop of the refrigerator; the oil cooler and the refrigerating machine are integrally arranged and fixed to one side of the exterior of the refrigerating machine through the supporting back plate and the hoop. The integral structure can avoid oil way damage caused by vibration of different frequencies due to split arrangement, and the integral arrangementis convenient to disassemble and assemble; a heat exchange loop of the oil cooler is in a bottom-in top-out mode, so that the circulation time of cooling liquid in the cooler is longer, and the cooling effect is more remarkab
