Description

External condenser of refrigerator

Technical Field

The utility model belongs to the technical field of the refrigerator accessory, especially, relate to an external condenser of refrigerator.

Background

The refrigerating system of the refrigerator consists of a compressor, a condenser, a capillary tube and an evaporator, which are connected into a sealed system by pipelines. The basic principle of refrigerator refrigeration is that an evaporator takes away heat in a box body through heat exchange; the condenser then dissipates heat to the air surrounding the tank by heat exchange. Therefore, heat dissipation of a refrigerator condenser is a problem which must be considered in a refrigeration system of the refrigerator. Currently, the condenser of a refrigerator is generally installed in the back of the refrigerator or in the compressor compartment. In order to increase the heat dissipation efficiency, the material is generally aluminum, steel or metal alloy. Because the cooling speed of the condenser directly influences the cooling speed of the refrigerator and the energy consumption of the refrigerator, how to increase the cooling efficiency of the condenser is a subject of continuous optimization in a refrigeration system of the refrigerator.

Chinese patent No. 201410060908.1 discloses a condenser assembly for a refrigerator and a refrigerator having the same; it comprises a condenser; the air inlet of the centrifugal fan is opposite to the condenser and is adjacent to the condenser, and the blades of the centrifugal fan are forward blades; the air inlet of the air exhaust duct is connected with the air outlet of the centrifugal fan, and the air outlet of the air exhaust duct is suitable for extending out of the compressor bin of the refrigerator; this patent is owing to increased the installation in wind channel of airing exhaust for the production technology of refrigerator is complicated, and production efficiency reduces.

Chinese patent No. 200610127026.8 discloses a refrigerator provided with a bottom condenser and a bottom condenser; the bottom of the refrigerator is provided with a mechanical chamber, a compressor, a reversing valve, a control panel and a condenser are arranged in the mechanical chamber, and the condenser is horizontally and fixedly arranged on the upper surface of a bottom plate of the refrigerator; this patent assembles embedded condenser and outer hanging condenser to the compressor storehouse through adopting special structural design to reach and increase heat exchange efficiency and pleasing to the eye effect, but the heat exchange efficiency of condenser does not obtain abundant promotion.

In order to solve the defects, an external condenser of the refrigerator is designed at present.
