Abstract
The utility model relates to an evaporator for a refrigerator, which comprises an evaporating tube and a heat transfer plate, wherein, the evaporating tube is tightly attached to the heat transfer plate which is provided with a continuous groove, the axis of the groove and the axis of the evaporating pipe are coincident, the cross sectional shape of the groove is matched with that of the evaporating tube, and the evaporating tube is arranged in the groove. The cross section of the heat transfer plate groove and the evaporating tube are all in a D shape. The degumming phenomenon of the tube and the plate of the utility model can not occur, and the heat transfer efficiency is higher.
Description
Technical field
The utility model belongs to art of refrigeration units, particularly relates to the evaporimeter that a kind of freezer compartment of refrigerator is used.
Background technology
The evaporimeter of domestic refrigerator refrigerating chamber, so-called R evaporimeter generally is the structure that adopts tube-sheet type.Existing R evaporimeter comprises evaporation tube and heat transfer plate, evaporation tube and heat transfer plate fit tightly, it fits tightly by PUR is bonding and forms with hot pressing, during production, evaporation tube and heat transfer plate are all coated PUR, hot pressing forms on special equipment, and its heat transfer plate reverse side is bonded on the refrigerating chamber wall of inner container with double faced adhesive tape again.Because evaporation tube is different with the material that heat transfer plate is used, there is some difference for its thermal conductivity factor and the line of material coefficient of expansion, and evaporation tube is come unstuck easily, separates with heat transfer plate, reduced heat transfer efficiency.When particularly adopting copper facing or coating steel pipe to make evaporation tube, because the resilience stress of steel pipe is big, this disadvantage is especially serious.
Summary of the invention
To be solved in the utility model is the segregative technical problem of evaporation tube and heat transfer plate, and the evaporator of refrigerator that a kind of tube sheet is combined, heat transfer efficiency is high is provided.
For this reason, the technical solution adopted in the utility model is as follows: evaporator of refrigerator, comprise evaporation tube and heat transfer plate, evaporation tube and heat transfer plate fit tightly, heat transfer plate is provided with continuous groove, the axis of groove is consistent with the axis of evaporation tube, and the cross sectional shape of groove matches with the cross sectional shape of evaporation tube, and evaporation tube is arranged in the groove.
The cross section of groove and evaporation tube can be square, also can be circular or other shapes, and reasonable scheme is that pipe is put into D shape groove, makes evaporation tube also become D shape after the compacting, fits tightly with heat transfer plate.
For obtaining better heat transfer efficiency, the contact area of evaporation tube and heat transfer plate is the bigger the better, the utility model requires the contact area of evaporation tube and heat transfer plate greater than 2/3 of its surface area, that is to say, the length that contacts with described trench cross section on the evaporation tube cross section surpasses 2/3 of its girth.
Evaporation tube of the present utility model is included in the heat transfer plate, on the same plane in the D shape plane of evaporation tube and heat transfer plate planar ends place,, not only exempted hot pressing processing with PUR again with two-sided gluing spreading on the refrigerating chamber wall of inner container, reduced production cost, and can not break away between tube sheet; The arc surface of D shape has increased the heat exchange area between tube sheet, has improved the efficient of evaporimeter.
Description of drawings
Fig. 1 and Fig. 2 are the structural representations of evaporimeter in the prior art.
Fig. 3 and Fig. 4 are structural representations of the present utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2.Original evaporator of refrigerator comprises heat transfer plate 11 and evaporation tube 12, and to fit together after the PUR hot pressing, the reverse side of heat transfer plate is bonded on the cold compartment of refrigerator wall of inner container with double faced adhesive tape 13 more between the two.As can be seen from Figure 2, evaporation tube 12 is to be pressed into oblately, be no more than 1/2 of its surface area with the contact-making surface of heat transfer plate 11, so its heat transfer efficiency is low, and both separates easily.
Referring to Fig. 3, Fig. 4.The groove that has D shape on the heat transfer plate 21 of the present utility model, evaporation tube 22 are put into after this groove, also are pressed into D shape, fit tightly with heat transfer plate, and both contact-making surfaces surpass 2/3 of evaporation tube surface area.The plane of evaporation tube D shape and heat transfer plate at grade, again with the sticking refrigerating chamber wall of inner container that spread on of double faced adhesive tape 23.
Claims (3)
1. evaporator of refrigerator comprises evaporation tube and heat transfer plate, and evaporation tube and heat transfer plate fit tightly, it is characterized in that: heat transfer plate is provided with continuous groove, the axis of groove is consistent with the axis of evaporation tube, and the cross sectional shape of groove matches with the cross sectional shape of evaporation tube, and evaporation tube is arranged in the groove.
2. evaporator of refrigerator as claimed in claim 1 is characterized in that: described trench cross section and evaporation tube cross section are " D " shape.
