Condenser, method for fabricating a condenser and cooling appliance having the condenser

Abstract

A cooling appliance includes a compressor, a condenser and a medium temperature tube. The condenser includes a first condenser and a second condenser. A refrigerant flowing out from the compressor sequentially passes through the first condenser, the medium temperature tube and the second condenser. The first condenser and the second condenser both include a condenser tube coiled into several layers and are fixed together by using a heat sink wire disposed on the condenser tube. The medium temperature tube can be a door anti-dew tube. A condenser of a cooling appliance and a method for fabricating a condenser are also provided.

Description

BACKGROUND[0001]Technical Field[0002]The present invention relates to the field of mechanical manufacturing, and more particularly to a condenser, a method for fabricating a condenser, and a cooling appliance having the condenser.[0003]Related Art[0004]A cooling appliance, especially a household refrigerator, freezer, wine cooler or the like, usually uses one sealed refrigeration circulation system that mainly includes basic components such as a compressor, a condenser, and an evaporator to implement refrigeration or freezing of food stored in a home appliance. An effect of the condenser is to convert a gaseous, high-temperature, high-pressure refrigerant flowing out from the compressor into a liquid refrigerant having a relatively low temperature.[0005]To prevent a condensation phenomenon from occurring at an opening of a cooling appliance, a door anti-dew apparatus is disposed near the door in the prior art. The door anti-dew apparatus may be formed by embedding an electrical heat...

AI Technical Summary

Benefits of technology

The patent describes a refrigeration system that includes a condenser with two layers of coiled tubes and a heat sink wire. This design helps to improve heat dissipation and minimize loss of cold air. The overall shape and volume of the condenser are not significantly changed, and the space required for installation is not increased. The two layers of coiled tubes and heat sink wire fit together to achieve a more desirable heat dissipation effect. Additionally, the patent suggests that a medium temperature tube can be welded between the two layers of coiled tubes, making installation and use easier.

Problems solved by technology

When the electrical heating wire is disposed, power consumption of the cooling appliance is additionally increased.

When the door anti-dew tube is used, if the door anti-dew tube is directly connected to a compressor and is then connected to the condenser, the temperature inside the door anti-dew tube may be excessively high and lower refrigeration efficiency of the cooling appliance, or if the high-temperature refrigerant is condensed by the condenser first to flow into the door anti-dew tube, the temperature may become excessively low to fail to implement an anti-dew function.

The medium temperature tube can be employed according to the invention at all places where both a sufficiently high temperature is needed to prevent condensation or freezing, and a too high temperature such as the refrigerant temperature when entering the first condenser is disadvantageous because it would reduce the energy efficiency of the appliance.
