At present, the structure of cold compartment of refrigerator evaporimeter has two kinds substantially: first kind is the external evaporimeter, and it is found in the refrigerating chamber, is suitable for the few occasion of refrigeration requirement, is applied in small volume refrigerator or simple refrigerating box more.Another kind is built-in evaporimeter, and it is embedded between alveolar layer and the inner container of icebox usually, and cold passes through inner container of icebox to the refrigerating chamber transmission.This evaporimeter comprises evaporation tube, heat transfer plate, and evaporation tube to heat transfer plate, is coated with one deck heat transfer glue with melt viscosity on the heat transfer plate, and the opposite side of heat transfer plate adheres to the back side of refrigeration courage through double faced adhesive tape.During the refrigerator operation, the bang path of cold is: air in aluminum pipe → heat transfer glue → heat transfer plate → double faced adhesive tape → inner bag → case.Its refrigerator evaporator pipe contacts through line or face with the heat transfer metal plate, and heat transfer efficiency is low, and power consumption is big.
Summary of the invention
The technical problem that the present invention will solve is, a kind of simple in structure, enhanced heat exchange effect, energy-conservation level new refrigerator refrigeration evaporator remarkable, with low cost is provided, to overcome the deficiency of prior art.
The technical scheme that the present invention adopted is: the new refrigerator refrigeration evaporator; Comprise evaporation tube and heat transfer plate; Said evaporation tube is provided with inlet and outlet; The inlet of said evaporation tube is connected with the miscellaneous part of refrigerator refrigeration system respectively with outlet, and said evaporation tube is a H type evaporation tube, has on the said heat transfer plate and the suitable H type groove of said H type evaporation tube; Said H type evaporator tube is placed in the H type groove on the heat transfer plate; Said H type evaporation tube contacts with refrigerating chamber inner bag face.
Preferably, the cross section of said H type evaporation tube is approximate rectangular, comprises four walls in upper and lower, left and right.
Preferably, the H type groove on the said heat transfer plate is left and right, three walls in bottom surface, three walls of said H type evaporation tube respectively with heat transfer plate on three walls of H type groove contact and transmit heat.
Preferably, the wall contact heat-exchanging of the 4th of said H type evaporation tube the wall and refrigerating chamber inner bag.
Preferably, the matched of the degree of depth of the H type groove on the said heat transfer plate and said H type evaporation tube.
Compared with prior art, the invention has the beneficial effects as follows:
1, evaporimeter heat transfer plate of the present invention is provided with H type groove, and three of H type evaporation tube respectively with heat transfer plate on three faces of H type groove contact and conduct heat, increased the contact area of evaporator tube and heat transfer plate, improved heat exchanger effectiveness.
2, the built-in refrigerating chamber inner bag outside that is placed on of H type evaporation tube fourth face of the present invention directly reaches refrigerating chamber through inner bag with heat, has the energy-conservation effect of augmentation of heat transfer.
3, cold compartment of refrigerator H type evaporation structure of the present invention is simple, and technological design is reasonable.Sheet material that evaporimeter consumes, tubing and existing evaporimeter are few, but can save evaporimeter are pasted on the aluminium foil on the heat transfer plate, make totle drilling cost lower than current evaporimeter.
Description of drawings
Fig. 1 is a new refrigerator refrigeration evaporator structural representation of the present invention;
Fig. 2 is A-A cutaway view of Fig. 1;
Fig. 3 is the B portion enlarged drawing of Fig. 2;
Fig. 4 is a refrigerator structure sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Shown in Fig. 1-4, refrigerator cold-storage evaporimeter 1 of the present invention comprises H type evaporation tube 2, heat transfer plate 3.Heat transfer plate 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 quickly with refrigerating chamber in air carry out the exchange of heat.
H type evaporation tube 2 is made up of a plurality of straightway pipelines and curved section pipeline; On heat transfer plate, 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, and usually, the inlet of the evaporation tube of refrigerating chamber is connected with the freezing chamber evaporator pipe and (supposes that refrigerator has refrigerating chamber and refrigerating chamber; And the evaporimeter of two Room is independent), the outlet of the evaporation tube of refrigerating chamber is then usually with liquid reservoir or directly be connected with the muffler of compressor.The length of evaporation tube has determined in the unit interval and the flow of the cold-producing medium of refrigerating chamber heat exchange; The effective heat exchange area of heat transfer plate then is the key factor that influences heat exchange area; Thereby; The cold that the refrigerator cold-storage evaporimeter 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 cold-storage evaporimeter of the present invention adopts H type evaporation tube; With respect to the R 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 R type evaporation tube is circular or oval.
The heat transfer plate 3 of refrigerator cold-storage evaporimeter 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 global shape, 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 cross section; Also be H type groove 4, 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 5 through inner bag again; The fourth face of H type evaporator tube 2 is horizontally set on refrigerating chamber inner bag one side, with cold directly in inner bag reaches refrigerating chamber 5.
Refrigerator cold-storage evaporation structure of the present invention is simple, 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.
