Description

CONDENSER, METHOD FOR FABRICATING CONDENSER, AND COOLING APPLIANCE HAVING THE CONDENSER
BACKGROUND
Technical Field 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.
Related Art
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. 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 heating wire in a case body at the opening, or a door anti-dew tube may also be disposed and heat that dissipates from a high-temperature refrigerant in a condenser is used to prevent condensation. 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. SUMMARY

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, and 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 arranged on the condenser tube.
The expression medium temperature tube refers to temperature of the refrigerant, which is in the medium temperature tube between the higher temperature in the first condenser and the lower temperature in the second condenser. The medium temperature tube can be employed as a door anti-dew tube, an anti-dew tube for preventing dew in different areas or an anti-freezing tube to prevent freezing of a dew water channel.

BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings below only provide schematic illustration and explanation for the present invention, and do not limit the scope of the present invention, where: FIG. 1 is a partial schematic view of refrigeration circulation according to a first embodiment of the present invention;
FIG. 2 is a perspective view of a condenser in a condenser combination in FIG. 1; and
FIG. 3 is a schematic exploded view of a condenser tube of a condenser in FIG. 2. DETAILED DESCRIPTION
To make the objectives, solutions, and beneficial effects of the present invention more obvious and comprehensible, the present invention is further described below with reference to the accompanying drawings and preferred embodiments.
Referring to FIG. 1, FIG. 1 is a partial schematic view of refrigeration circulation according to a first embodiment of the present invention. A condenser 10, 20 in FIG. 1 is installed in a refrigeration circulation system in a cooling appliance. The cooling appliance may be a home electrical refrigerator, freezer, wine cooler or the like. The refrigeration circulation system includes a compressor 11 disposed at one side of the condenser 10, 20 and connected to the condenser 10, 20 and a medium temperature tube 12 connected to the condenser 10, 20.
The condenser 10, 20 is formed of a condenser tube and a heat radiation wire. The condenser tube is generally made of metal copper, and is first bent and arranged inside one plane, then metal heat sink wires 30 are separated at a certain distance and welded above or below the condenser tube 10, 20 in parallel to each other, and finally the condenser tube 10, 20 attached with the metal heat sink wires 30 is coiled to form a spiral condenser tube array. The condenser tube 10, 20 is spirally coiled into a circular shape in a transverse direction of the condenser tube array, and the heat sink wire 30 extends in parallel in a longitudinal direction of the condenser tube array.
FIG. 3 is a schematic view of a condenser tube being bent and arranged in one plane. FIG. 2 is a schematic view of the condenser tube located in one plane in FIG. 3 being coiled to form a spiral condenser tube array. As can be seen from FIG. 3, the condenser tube 10, 20 in this embodiment includes two parts, a first condenser 10 and a second condenser 20, separately. The first condenser 10 and the second condenser 20 are fixed on a same base 50. Metal heat sink wires 30 having an equal interval and arranged in parallel are welded above or below the condenser tube 10, 20. The first condenser 10 includes a port C and a port A. The second condenser 20 includes a port B and a port D. In FIG. 2, the volume of the condenser 10, 20 is hardly different from the volume of the condenser 10, 20 in the prior art, and a difference in appearance lies in that the condenser 10, 20 has four ports A, B, C, and D, whereas the condenser 10, 20 in the prior art only has an outlet and one inlet.
The first condenser 10 and the second condenser 20 are not directly connected, and a medium temperature tube 12 is connected between the first condenser 10 and the second condenser 20. In FIG. 1, an inlet C of the first condenser 10 is connected to a compressor 11, an outlet A of the first condenser 10 is connected to an inlet F of the medium temperature tube 12, an inlet E of the medium temperature tube 12 is connected to an inlet B of the second condenser 20, and an outlet D of the second condenser 20 is connected to a capillary tube, an evaporator, and the like in the back.
A high-temperature refrigerant flowing out from the compressor 11 sequentially flows through the first condenser 10, the medium temperature tube 12, and the second condenser 20. The refrigerant flowing into the medium temperature tube 12 has undergone condensation and heat dissipation by the first condenser 10, and therefore the temperature is lower than the temperature of the refrigerant that directly flows out from the compressor 11. In the premise of meeting prevention of condensation at a refrigerator door, the refrigeration efficiency of the refrigerator is reduced to the minimum extent. The temperature of the refrigerant inside the medium temperature tube 12 may be set by arranging the length of the first condenser 10 and the second condenser 20. For example, to make the temperature of the refrigerant inside the medium temperature tube 12 relatively high, the length of the first condenser 10 is reduced. In contrast, to make the temperature of the refrigerant inside the medium temperature tube 12 relatively low, the length of the first condenser 10 is increased. Generally, a length ratio of the first condenser 10 to the second condenser 20 is set between 1 :2 and 2: 1. In a preferred embodiment, the first condenser 10 and the second condenser 20 are equal in length.
The present invention further proposes a method for fabricating a condenser, which includes the following step: coiling two segments of condenser tubes into several layers respectively to form a first condenser 10 and a second condenser 20; and fixing the first condenser 10 and the second condenser 20 together by using a heat sink wire 30 arranged on the condenser tubes, and then fixing the first condenser 10 and the second condenser 20 on a same base 50, so as to improve an effect of fixing the first condenser 10 and the second condenser 20. The refrigeration circulation system in this embodiment is used in a refrigerator, and more over, the refrigeration circulation system is also applicable to a wine cooler or a freezer.
