Abstract
To prevent dew formation of a refrigerator efficiently by providing a heat exchanger for exchanging heat from first refrigerant tube to second refrigerant tube, and a bypass valve for preventing counter flow of the second refrigerant to one side of the second refrigerant tube. A second independent closed loop refrigerant tube 220 passing second refrigerant is arranged between the compressor 100 and the condenser 130 of a first refrigerant tube 160 while extending to the first refrigerant tube 160 constituting the cooling circuit of a refrigerator through a partitioning part. A heat exchanging section 200 for exchanging heat from the first refrigerant tube 160 to the second refrigerant tube 220 is disposed between the compressor 100 and the condenser 130 along with a bypass valve 240 for preventing counter flow of the second refrigerant to one side of the second refrigerant tube 220. The second refrigerant tube 220 abuts against the first refrigerant tube 160 coupling the discharge opening of the compressor 100 with the suction opening of the condenser 130 over a specified length or longer. According to the arrangement, freezing phenomenon of the refrigerator can be prevented continuously when the compressor 100 is operating.
Description
The present invention relates to a kind of anti-condensation device of refrigerator, especially so a kind of anti-condensation device, it has the auxiliary refrigerant pipeline that is the closed-loop path shape, spreads out of heat by the main refrigerant pipeline that flows through from high temperature refrigerant gas, avoids at the front portion and the dividing plate place of refrigerator the dewfall phenomenon taking place.
Usually, domestic refrigerator has refrigerating chamber, refrigerating chamber and refrigerator is divided into the dividing plate of two chambers.Refrigerating chamber, refrigerating chamber and dividing plate inside have heat preservation member, usually in order to the temperature of Keep cool chamber and refrigerating chamber.
In traditional refrigerator and since extraneous warm air with circulate in the temperature difference that is produced when two indoor cold airs contact, periphery generation dewfall phenomenon two chambers.
Because the dewfall phenomenon appears at the periphery of two chambers, the outer surface of refrigerator body is made dirty, needs often cleaning refrigerator body.
In addition, if form dewfall between the casing that forms the fridge exterior face and built-in heat preservation member, and dewfall is partly freezed thereupon, forms a gap between casing and heat preservation member.
Extraneous hot-air flows into refrigerator by the gap, has therefore destroyed the refrigeration balance in the refrigerator, and the function of refrigerator is unusual gradually thus.
In order to address this problem, traditional refrigerator has a heat pipe 20.
As shown in Figure 1, heat pipe 20 is formed into the elongated portion of the refrigerant pipe 60 that connects compressor 10 and condenser 30, and places refrigerating chamber, the front portion of refrigerating chamber and dividing plate.
The heat of the refrigerant gas of discharge and inflow heat pipe 20 makes dew evaporation and the disappearance in two chambers and the formation of dividing plate periphery from compressor 10.
In the refrigerator refrigerant peripheral passage of above-mentioned heat pipe 20 was installed, cold-producing medium flowed out from compressor 10, cycles through heat pipe 20, condenser 30, capillary 40, and evaporimeter 50, and enter compressor 10 once more.
Yet because the extension of heat pipe 20 is installed, the cold-producing medium peripheral passage is extended, and has therefore increased the on-way resistance of cold-producing medium, causes the load coefficient of compressor 10 to increase.Therefore, increase the running time of compressor 10, causes reduce the service life of compressor 10.
According to experiment test, the main positions that the dewfall phenomenon takes place is the periphery of dividing plate rather than refrigerating chamber.
Yet because heat pipe 20 is positioned at refrigerating chamber, the cold-producing medium heat of high temperature looses into that refrigerating chamber surpasses its design temperature to increase temperature.Raise in order to compensate for this temperature, the load coefficient of compressor 10 increases and the additive decrementation electric energy, and reduces the service life of compressor 10.
