For the problems referred to above and defect, traditional method is before refrigerator foaming, reduce the residual gas before foaming around built-in evaporimeter by the method for structural design or mechanical presses as far as possible, but in actual foaming process, the foam rolling of flowing can form cavity when covering the built-in evaporator surface of refrigerator, still can remain a small amount of gas.
Summary of the invention
The present invention be directed to the weak point existing for above-mentioned prior art, a kind of built-in evaporator refrigerator with exhaust passage is proposed, effectively can drain the gas around evaporator pipeline, ensure the heat-conductive characteristic of evaporimeter, avoid refrigerator heat-insulation layer " bubbling " phenomenon in foaming process simultaneously.
The present invention is technical solution problem, adopts following technical scheme.
A kind of built-in evaporator refrigerator with exhaust passage of the present invention, the outer surface that built-in evaporimeter is evenly arranged in refrigerator lining with its evaporation tube forms refrigerating layer, it is the heat-insulation layer formed by foamable reaction between outcase of refrigerator and refrigerating layer, it is characterized in that: the heat-transfer film that the built-in evaporimeter of a covering is set between heat-insulation layer and refrigerating layer, heat-transfer film forms package structure to evaporation tube, and forms air gap channel between the gap of each evaporation tube; The exhaust passage being provided with and being connected with each air gap channel is lining with interior, exhaust passage is offered the steam vent be connected with liner madial wall, and the gas between each evaporation tube gap is converged in an exhaust gas and is discharged into outside refrigerator by steam vent in foamable reaction process.
The design feature of the built-in evaporator refrigerator with exhaust passage of the present invention is:
Pressure-sensitive adhesive layer is provided with between heat-transfer film and refrigerating layer.
Exhaust passage is the groove be lining with in being arranged on.
The lateral wall of liner arranges an air guide paper tape, and exhaust passage is the gap between air guide paper tape and liner.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is enclosed with stretchable heat-transfer film by covering at the outer surface of built-in evaporimeter, heat-transfer film is comparatively level and smooth before refrigerator foaming, expanding foam solution can be avoided to form cavity at the initial stage of flowing of expanding, and utilize the stretchable characteristic of heat-transfer film, high temperature in the late stage of foamed solidification, the condition of high pressure, the heat-transfer film outside evaporimeter is made to produce tensile deformation, evaporation tube surrounding air gap reduces, thus the gas around evaporator pipeline is discharged into outside case via exhaust passage, the bonding effect of pressure sensitive adhesive improves simultaneously, the heat exchange efficiency of evaporimeter is improved, reduce the energy consumption of refrigerator.
2, present invention utilizes the air gap channel of evaporation tube both sides self-assembling formation, and the exhaust passage that design and air gap channel interconnect, thus evaporation tube surrounding air is discharged, the heat-transfer effect of heat-transfer film gets a promotion simultaneously.
3, expanding foam solution and exhaust passage separate by the heat-transfer film of the present invention's design, by the structure of groove or the setting being vented paper tape, to ensure in refrigerator foaming technical process steam vent can not block by the emplastic such as expanding foam solution, pressure sensitive adhesive.

Detailed description of the invention
In the present embodiment, as shown in Figure 1, the outer surface that built-in evaporimeter is evenly arranged in refrigerator lining 2 with its evaporation tube 1 forms refrigerating layer, as shown in Figure 2, be the heat-insulation layer 3 formed by foamable reaction between outcase of refrigerator and refrigerating layer, built-in evaporimeter is imbedded between liner 2 and heat-insulation layer 3; As shown in Figure 3, a kind of built-in evaporator refrigerator with exhaust passage is the stretchable heat-transfer film 5 arranging the built-in evaporimeter of a covering between heat-insulation layer 3 and refrigerating layer, heat-transfer film 5 pairs of evaporation tubes 1 form package structure, and form air gap channel 7 between the gap of each evaporation tube; Heat-transfer film 5 is comparatively level and smooth before refrigerator forms the foaming stages of heat-insulation layer 3, and expanding foam solution can be avoided to form cavity at the initial stage of expansion flow process.
In concrete enforcement, the material of stretchable heat-transfer film 5 can adopt wrinkle aluminium foil, and wrinkle aluminium foil contacts the one side coating pressure sensitive adhesive of built-in evaporimeter.Namely between heat-transfer film 5 and refrigerating layer, pressure-sensitive adhesive layer 6 is provided with.In the later stage of foamed solidification, liquid foamed material can produce high temperature, high pressure, and there is tensile deformation in heat-transfer film 5 under the effect of high temperature, high pressure, evaporation tube 1 surrounding air gap is compressed reduction, the bonding effect of pressure sensitive adhesive also improves simultaneously, the heat exchange efficiency of built-in evaporimeter is improved, thus reduces the energy consumption of refrigerator.
As shown in Figure 1, liner 2 is provided with the exhaust passage 4 be connected with each air gap channel 7, exhaust passage 4 is offered the steam vent 41 be connected with liner 2 madial wall, and the gas between each evaporation tube gap to be converged in exhaust passage 4 and is discharged into outside refrigerator by steam vent 41 in foamable reaction process.
As shown in Figure 4, exhaust passage 4 is for being arranged on the groove 42 on liner 2.Expanding foam solution and exhaust passage 4 separate by heat-transfer film 5, ensure steam vent 41 in refrigerator foaming technical process on exhaust passage 4 can not block by the emplastic such as expanding foam solution, pressure sensitive adhesive.
As shown in Figure 5, the lateral wall of liner 2 arranges an air guide paper tape 43, exhaust passage 4 is the gap between air guide paper tape 43 and liner 2.Concrete, air guide paper tape 43 is fixed on liner 2 with its one side by pressure sensitive adhesive, for being communicated with each air gap channel 7, cover on steam vent 41 simultaneously and also and between liner 2 form gas flow, thus the gas around evaporation tube 1 can be put into outside casing by the interstitial row between air guide paper tape and liner.Meanwhile, pressure-sensitive adhesive layer 6 and steam vent 41 separate by air guide paper tape 43, also to ensure in refrigerator foaming technical process steam vent 41 can not block by the emplastic such as expanding foam solution, pressure sensitive adhesive.
