Abstract
The utility model discloses a refrigerator heat exchanger which comprises a refrigerating chamber heat exchanger and a freezing chamber heat exchanger. The freezing chamber heat exchanger comprises a direct-cooling refrigerator freezing heat exchanger and an air-cooling refrigerator freezing heat exchanger. The refrigerator heat exchanger is characterized in that the direct-cooling refrigerator freezing heat exchanger is composed of an S-shaped pipe and steel wires which are welded on the upper face and the lower face of the S-shaped pipe, one end of the S-shaped pipe is 9-shaped, the other end of the S-shaped pipe is semi-circle-shaped, and an erosion resistant layer is arranged on the S-shaped pipe and the steel wires. The refrigerator heat exchanger has the advantages of enabling the design of a freezing chamber to be simplified, enabling effectively used space of the freezing chamber to be enlarged, being attractive and elegant in appearance and simple in craft manufacturing, reducing design and manufacturing cost effectively, enabling the temperature of the whole freezing space to be even and meeting the requirements that electricity is saved and service life of a refrigerator is prolonged.
Description
Technical field
The utility model relates to a kind of refrigerator heat exchanger, is specifically related to the freezing heat exchanger of a kind of direct cooling refrigerator.
Background technology
The most refrigerator design will have the super large refrigerating chamber, and refrigerating chamber not only will have super large refrigerating capacity and quick-frozen function, but also should fully guarantee the temperature homogeneity of cold and the whole refrigerating chamber of refrigerating chamber, also energy-saving and cost-reducing characteristics etc. will be arranged simultaneously.At present conventional refrigerating evaporator design, about the refrigerating chamber inside, there is the larger temperature difference in all around etc., whole refrigerating chamber internal temperature does not have uniformity, two high-temperature region temperature of the superiors and orlop often do not reach the GB requirement, press is worked long hours, increase power consumption, have larger design drawback.So during present refrigerator freezing design of heat exchanger, in order to guarantee that refrigerating chamber upper, middle and lower temperature satisfies the GB requirement, usually make the heat exchanger of the superiors and orlop high-temperature region adopt additional heat exchanger or the superiors and orlop to adopt respectively the two superimposed mode to strengthen the refrigeration evaporator area, freezer compartment of refrigerator is when structural design like this, the additional heat exchanger that will add for the superiors and orlop or the bilayer stack heat exchanger that adds provide enough spaces, cause the drawbacks such as production process technology is complicated, cost of raw material increase, space resources waste.
The utility model content
The technical problems to be solved in the utility model provides a kind of saves energy, prolongs the refrigerator refrigerator heat exchanger in service life.
The technical solution of the utility model is: the refrigerator heat exchanger comprises refrigerating chamber heat exchanger and refrigerating chamber heat exchanger, the refrigerating chamber heat exchanger comprises the freezing heat exchanger of direct cooling refrigerator and the freezing heat exchanger of wind cooling refrigerator, it is characterized in that: the freezing heat exchanger of described direct cooling refrigerator is comprised of coiled pipe, the steel wire that is welded on the coiled pipe upper and lower surface, described coiled pipe one end is shaped as " 9 " font, the other end is shaped as " semicircle " shape, and an anticorrosive coat is arranged on described coiled pipe and the steel wire.
The beneficial effects of the utility model are: freezing heat exchanger molding structure one end of direct cooling refrigerator adopts " 9 " font in the utility model, the other end adopts " semicircle ", both can the close-packed arrays moulding between the pipeline, pipeline arc transition section is unlikely to again to occur dog leg, can satisfy again the refrigeration area of the refrigerating chamber the superiors and two high-temperature region refrigeration systems of orlop simultaneously.The utility model can make refrigerating chamber design simplification, and the space effectively utilizes large, the appearance looks elegant atmosphere, technique is made and simply, is effectively reduced the designing and making cost, make simultaneously whole reefer space temperature have uniformity, satisfy saves energy, the purpose that prolongs the service life of refrigerator.
The utility model can make refrigerating chamber design simplification, the space effectively utilizes large, the appearance looks elegant atmosphere, technique simply, effectively reduces the designing and making cost,, can satisfy the refrigerating chamber the superiors again and the orlop temperature satisfies the GB requirement, whole space temperature uniformity, saves energy, the service life of prolongation refrigerator.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is pipeline profile of the present utility model;
Fig. 3 is schematic diagram of refrigerating of the present utility model.
The specific embodiment
Such as Fig. 1-3, the refrigerator heat exchanger comprises refrigerating chamber heat exchanger and refrigerating chamber heat exchanger, and the refrigerating chamber heat exchanger comprises the freezing heat exchanger of direct cooling refrigerator and the freezing heat exchanger of wind cooling refrigerator.The freezing heat exchanger of described direct cooling refrigerator is comprised of coiled pipe 1, the steel wire 2 that is welded on coiled pipe 1 upper and lower surface, and described coiled pipe one end is shaped as " 9 " font, and the other end is shaped as " semicircle " shape, and an anticorrosive coat 3 is arranged on described coiled pipe 1 and the steel wire 2.
Two tubes center distance with " 9 " font end A is 24mm, and port tube subcenter layer bending radius is R22; Having two continuous pipeline moulding center distance of " semicircle " shape end B is 44mm.Freezing radiator links together by tube connector and refrigeration heat exchanger, throttle pipe, radiator, compressor, forms the system of sealing, and cold-producing medium flows in the system of sealing, finishes kind of refrigeration cycle.The utility model also can be used in other refrigerating appliances.
Coiled pipe be " Bandaid pipe " by shaping mechanism bending " snakelike shape ", steel wire weld is at the upper and lower surface of hosepipe, coiled pipe and Steel Wire Surface are soaked and are moulded anticorrosive coat.Coiled pipe moulding head one end adopts " 9 " font, and the other end adopts " semicircle ", can encrypt compact arrangement during the pipeline moulding, increases heat exchange area, satisfies the required refrigerating capacity of the refrigerating chamber the superiors and orlop.The Bandaid pipe just refers to that diameter is at the fine steel tube of 4.6-10.6.Mainly get drain, wireway as automobile, refrigerator.
