Evaporation plate 10; Muffler 20; Heat exchange layer 30; Capillary 40.
Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
The inflation type evaporator 100 according to the embodiment of the present invention is specifically described below in conjunction with accompanying drawing 1.
The inflation type evaporator 100 of embodiment comprises muffler 20, heat exchange layer 30 and capillary 40 according to a first aspect of the present invention.Specifically, heat exchange layer 30 is located on the outer surface of pipeline section at least partially of muffler 20, and capillary 40 extends ground winding in heat exchange layer 30 along the axis of muffler 20.
Particularly, as shown in Figure 1, inflation type evaporator 100 forms primarily of evaporation plate 10, muffler 20, heat exchange layer 30 and capillary 40.Wherein one end of muffler 20 is connected with evaporation plate 10, the outer surface of the pipeline section at least partially of muffler 20 is provided with heat exchange layer 30, capillary 40 is connected with evaporation plate 10 in heat exchange layer 30 and with one end of capillary 40 along the axial winding of muffler 20, be understandable that, capillary 40 winding on muffler 20, and is provided with heat exchange layer 30 between capillary 40 and muffler 20.
And the inflation type evaporator in correlation technique mainly contains two kinds of versions, wherein a kind of version of inflation type evaporator be by capillary directly closely winding on muffler, the inflation type evaporator of this kind of structure directly contacts with capillary due to muffler, therebetween heat exchange is too concentrated, the refrigerant phase at this region place is easily caused to occur sharply to change, thus send noise, seriously affect user and use.
And the version of another kind of inflation type evaporator be capillary along muffler axial parallel be located on muffler, and the muffler position overlapping with capillary be provided with thermal conductivity preferably material with fixed capillary, the inflation type evaporator heat exchange of this kind of structure is even, but arrange because muffler and capillary walk abreast, the heat exchange area of muffler and capillary is reduced, in order to ensure certain heat exchange amount, need the extended length of muffler, considerably increase taking up room of muffler, too increase cost, moreover, the length of the capillary of evaporimeter is general longer, workman is when installing refrigerator, remaining capillary need to be looped process, greatly reduce efficiency of assembling.
Thus, according to the inflation type evaporator 100 of the embodiment of the present invention, by capillary 40 winding on muffler 20, considerably increase the heat exchange area of muffler 20 and capillary 40, make the two can reach abundant heat exchange, moreover, make capillary 40 fitly winding on muffler 20, reduce taking up room of capillary 40, improve efficiency of assembling, by arranging heat exchange layer 30 on the outer surface of the pipeline section at least partially of muffler 20, make heat exchange layer 30 by muffler 20 and the spaced apart setting of capillary 40, thus the concentrated heat exchange reduced between muffler 20 and capillary 40, and then reduce the noise that inflation type evaporator 100 sends in the course of the work.
Particularly, according to one embodiment of present invention, heat exchange layer 30 is set on muffler 20, the outer surface of the inner surface laminating muffler 20 of heat exchange layer 30.
In other words, heat exchange layer 30 can be formed as tubulose, and heat exchange layer 30 is set on muffler 20, and particularly, the inner surface of heat exchange layer 30 and the outer surface of muffler 20 are fitted, and capillary 40 forms the outer surface of helical form winding in heat exchange layer 30.Be understandable that, capillary 40 is less than or equal to the axial length of heat exchange layer 30 along the axially extended length of muffler 20, capillary 40 is wrapped on the outer surface of heat exchange layer 30 of muffler 20, substantially increase the heat exchange area of muffler 20 and capillary 40, make the two can reach abundant heat exchange, moreover, heat exchange layer 30 is located between muffler 20 and capillary 40, avoid to be formed therebetween and concentrate heat exchange, greatly reduce the noise sent due to concentrated heat exchange between muffler 20 and capillary 40.
Alternatively, according to one embodiment of present invention, heat exchange layer 30 is thermal conductivity flame-retardant layer.Preferably, heat exchange layer 30 is thermal conductivity flame-retardant sponge adhesive tape.
Thus, by heat exchange layer 30 is set to thermal conductivity flame-retardant sponge adhesive tape, make both can carry out heat exchange between the muffler 20 of inflation type evaporator 100 and capillary 40, can avoid again causing concentrated heat exchange, when not affecting heat exchange between muffler 20 and capillary 40, reduce the noise that inflation type evaporator 100 sends in the course of the work, moreover due to the material of heat exchange layer 30 be sponge adhesive tape, heat exchange layer 30 is located between muffler 20 and capillary 40, can be avoided muffler 20 and collide with capillary 40.
Particularly, according to one embodiment of present invention, the winding of thermal conductivity flame-retardant sponge adhesive tape is on muffler 20.
Thus, by arranging thermal conductivity flame-retardant sponge adhesive tape between muffler 20 and capillary 40, concentrated heat exchange between the muffler 20 of inflation type evaporator 100 and capillary 40 is weakened, thus reduce the noise that inflation type evaporator 100 sends in the course of the work, and thermal conductivity flame-retardant sponge adhesive tape structure is simple, cost is low, in use, can directly by the winding of thermal conductivity flame-retardant sponge adhesive tape on muffler 20, convenient operation, mounting or dismounting are convenient.
Wherein, according to one embodiment of present invention, capillary 40 and muffler 20 are respectively copper pipe.Because capillary 40 and muffler 20 are copper pipe, the two material is identical, if capillary 40 is directly arranged on muffler 20, very easily cause concentrated heat exchange, inflation type evaporator 100 is made to send noise in the course of the work, affect user's auditory perception, by arranging heat exchange layer 30 between capillary 40 and muffler 20, wherein heat exchange layer 30 can be thermal conductivity flame-retardant sponge adhesive tape, by the heat exchange form that the copper in correlation technique-copper heat exchange formal transformation is copper-sponge-copper, greatly reduce concentrated heat exchange therebetween, reduce noise.
Specifically describe the refrigeration system of embodiment according to a second aspect of the present invention below.
The inflation type evaporator 100 of above-described embodiment is comprised according to the refrigeration system of the embodiment of the present invention.That is, according to the refrigeration system of the embodiment of the present invention inflation type evaporator 100 primarily of condenser (not shown), compressor (not shown) and above-described embodiment, particularly, the two ends of inflation type evaporator 100 are connected with compressor with condenser respectively, wherein the muffler 20 of inflation type evaporator 100 is provided with heat exchange layer 30, this heat exchange layer 30 can be thermal conductivity flame-retardant sponge adhesive tape, and capillary 40 winding of inflation type evaporator 100 is on the muffler 20 being provided with heat exchange layer 30.
Thus, according to the refrigeration system of the embodiment of the present invention, by arranging heat exchange layer 30 on the muffler 20 of refrigeration system, make to avoid concentrated heat exchange between the muffler 20 of inflation type evaporator 100 and capillary 40, greatly reduce the noise that inflation type evaporator 100 sends at work, and capillary 40 winding is on muffler 20, reduce taking up room of capillary 40, and it is in good order to make capillary 40 arrange, is convenient to the assembling of subsequent parts, improves efficiency of assembling.
