[0019] A plurality of air outlet windows are provided on the condensation air duct cover plate 8 at the bottom of the box, and the air that has absorbed heat is discharged through the air outlet windows. The compressor compartment rear plate 6 is fixedly connected to the compressor compartment side plate 10 at the rear side, and a plurality of air inlet windows are provided on the compressor compartment rear plate 6 and the ventilation front window plate 7. Air at normal temperature is injected into the sealed body through the air inlet windows on the front and rear sides, and its heat is taken away by the microchannel condenser 2 to achieve heat dissipation of the microchannel condenser 2, and the hot air is discharged through the air outlet windows.

[0020] A condensing fan 1 is fixedly connected to the top of the refrigerator bottom plate 11 to blow the wind from the left side to the right side. A fan bracket sponge 3 is fixedly connected to the top of the refrigerator bottom plate 11. The fan bracket sponge 3 can flow air. The fan bracket sponge 3 is fixedly connected to the microchannel condenser 2 at one end close to the condensing fan 1. The condensing fan 1, the fan bracket sponge 3 and the microchannel condenser 2 are all embedded settings. A high-temperature medium flows in the microchannel condenser 2. The outside air takes away its heat through the microchannel condenser 2, turning the outside air into hot air. This technology is a prior art and will not be repeated here. The microchannel condenser 2 is arranged in a serpentine shape to increase the contact area between the high-temperature medium and the air.

[0021] The microchannel condenser 2 is fixed to the side wall of the fan bracket sponge 3 by bonding, and the top of the refrigerator bottom plate 11 is fixedly connected with the condensing fan bracket rear sealing seat 4, and the two ends of the condensing fan bracket rear sealing seat 4 are respectively fixedly connected to the condensing fan 1 and the fan bracket sponge 3, and the condensing fan bracket rear sealing seat 4 is L-shaped, and the top of the refrigerator bottom plate 11 is fixedly connected with the box bottom condensing air duct partition 5, and the fan bracket sponge 3 and the box bottom condensing air duct partition 5 are set against each other at opposite ends, and space separation is achieved by the cooperation of the fan bracket sponge 3 and the box bottom condensing air duct partition 5, so that air flows only through the fan bracket sponge 3, and the air contacts the microchannel condenser 2 to take away the heat from the microchannel condenser 2, thereby realizing the heat dissipation of the microchannel condenser 2.

[0022] In the utility model, outside air enters through the air inlet windows on the compressor compartment rear plate 6 and the ventilation front window plate 7, and forms a closed isolation through the fan bracket sponge 3 and the condensation duct partition plate 5 at the bottom of the box, so that the contact area between the air and the condenser is large, and the air takes away its heat through the condenser to achieve heat dissipation of the condenser, and the hot air is discharged through the air outlet windows on the condensation duct cover plate 8 at the bottom of the box. The wind flow path forms an inverted U-shaped duct (cooperation of the ventilation front window plate 7 and the condensation duct cover plate 8 at the bottom of the box) and a Z-shaped duct (cooperation of the compressor compartment rear plate 6 and the condensation duct cover plate 8 at the bottom of the box).

[0023] The utility model solves the problem in the prior art that the wind blown by the fan passes around the condenser, resulting in a small contact area between the air and the condenser, and there is a poor heat dissipation effect on the condenser.
