The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Shown in Fig. 1-5; Refrigerator refrigerating evaporator 1 of the present invention is arranged in the refrigerating chamber of refrigerator; Comprise evaporation tube 2 and heat transfer plate 3, evaporation tube is provided with inlet and outlet, and the inlet of evaporation tube is connected with the miscellaneous part of refrigerator refrigeration system respectively with outlet; Evaporation tube 2 is H type evaporation tubes, has on the heat transfer plate 3 and the suitable H type groove 4 of said H type evaporation tube; H type evaporator tube is inlaid in the H type groove 4 on the heat transfer plate 3, and H type evaporation tube is provided with up, and it lies on the bottom surface of H type groove 4.Heat transfer plate 3 is preferably processed with metal material; Like aluminium sheet; But be not inevitable so, so long as the good material of pyroconductivity and help manufacturing for good, so; The cold that will help the cold-producing medium in the H type evaporation tube fast, discharge fully, thereby and be delivered on the heat transfer plate 3 quickly with refrigerating chamber 6 in air carry out the exchange of heat.
H type evaporation tube is made up of a plurality of straightway pipelines and curved section pipeline; On heat transfer plate 3, arrange at certain intervals; Wherein, straightway pipeline and curved section pipeline join end to end and connect the formation evaporation tube, the outlet of an inlet and an evaporation tube that makes it to become an integral tube line structure and form an evaporation tube; The inlet of its evaporation tube, the outlet of evaporation tube are the parts that is connected with the refrigeration system miscellaneous part; Usually, the inlet of the evaporation tube of refrigerating chamber is connected with capillary, and the outlet of the evaporation tube of refrigerating chamber then is connected with refrigerator evaporator usually.The length of evaporation tube has determined in the unit interval and the flow of the cold-producing medium of refrigerating chamber 6 heat exchanges; The effective heat exchange area of heat transfer plate 3 then is the key factor that influences heat exchange area; Thereby; The cold that the refrigerator refrigerating evaporator can provide is that the factor by the common restriction of effective heat exchange area of length and the layout of evaporation pipeline, heat transfer plate 3 determines, in technique known, considers the moulding process property of evaporation tube curved section pipeline; Evaporation tube curved section pipe diameter is about 80mm, and the spacing of adjacent evaporation tube straightway pipeline also is 80mm.Refrigerator refrigerating evaporator of the present invention adopts H type evaporation tube; With respect to the F type evaporation tube that generally uses now; Its feature is that the cross section of evaporation tube is approximate rectangular, comprises four walls in upper and lower, left and right, and the cross section of F type evaporation tube is circular or oval.
As shown in Figure 1, around evaporimeter heat transfer plate 3 of the present invention, have bar seam 5, bar seam 5 also can be replaced by a plurality of holes.As shown in Figure 5, a plurality of refrigerator refrigerating evaporators 1 are set in freezer compartment of refrigerator, refrigerator refrigerating evaporator 1 is horizontally set in the refrigerating chamber 6 with certain spacing, makes refrigerating chamber form the interval 7 of a plurality of storings.Wherein, the end face of pressing close to refrigerating chamber is provided with first refrigerator refrigerating evaporator 1.In each interval 7, all be placed with cold chamber drawer 8, cold chamber drawer 8 directly is placed on refrigerator refrigerating evaporator 1 top.Owing to have bar seam 5 or hole around the evaporimeter heat transfer plate 3; Make the gas between each chamber 7 shuttle back and forth mobile at seam of the bar on the evaporimeter heat transfer plate 3 or hole; Driving cold flow moves between each chamber 7; Air between each chamber 7 is circulated each other, make the temperature field between each chamber 7 even, avoided the big problem of the temperature difference between each chamber 7.
The heat transfer plate 3 of refrigerator refrigerating evaporator of the present invention adopts aluminium sheet or other metallic plate, and heat transfer plate 3 is provided with and the suitable evaporation tube seat of H type evaporation tube 2 global shapes, is used to hold H type evaporation tube; Therefore; The degree of depth of groove and the matched of evaporation tube, and the cross section of evaporation tube seat is identical with H type evaporation tube 2 cross sections; Also be H type groove, comprise left and right, three walls in bottom surface.Therefore; In H type evaporation tube 2 is placed in the H type groove 4 of heat transfer metal plate 3 of evaporimeter; 2 three of H type evaporation tubes respectively with heat transfer metal plate 3 on the heat transfer that contacts of three faces of facing the wall and meditating of H type groove 4, H type evaporation tube 2 is passed to heat transfer metal plate 3 with heat through three faces of facing the wall and meditating of H type groove 4 earlier, reaches refrigerating chamber 6 through drawer 5 again; The fourth face of H type evaporator tube 2 is horizontally set on refrigerating chamber 6 drawers 5 one sides, with cold directly in drawer 5 reaches refrigerating chamber 6.
Refrigerator refrigerating evaporator of the present invention is simple in structure, and technological design is reasonable, and augmentation of heat transfer greatly reduces power consumption, and energy-saving and emission-reduction have the huge social benefit.
Above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to the foregoing description.Those skilled in the art is under the situation of creative work, the simple change of making, remodeling, adds or is equal to replacement, all should belong to protection scope of the present invention.
