The built-in condenser includes a left outlet pipe, a left condenser pipe, a transition pipe, a right condenser pipe, and a right outlet pipe connected in sequence. The serpentine tube condenser includes an inlet pipe copper tube, a manifold, a porous serpentine flat pipe, and an outlet pipe copper tube. The manifold is arranged at the upper right end and the lower left end of the porous serpentine flat pipe. One end of the inlet pipe copper tube is connected to the inlet pipe, and the other end is inserted into the manifold located at the upper right end of the porous serpentine flat pipe. One end of the outlet pipe copper tube is inserted into the manifold located at the lower left end of the porous serpentine flat pipe, and the other end is connected to the left outlet pipe or the right outlet pipe. The utility model can be compatible with more cabinet models, improve the versatility of components, improve the reliability of refrigerator use, and reduce the risk of burns to users under extreme conditions."

At the same time, it is not convenient to disassemble and clean. Secondly, the fan blades of the heat dissipation component will also be adhered to by dust, resulting in a reduction in the heat dissipation effect. Utility Model Content
