The specific embodiment
Below, in conjunction with the accompanying drawings, embodiments of the invention are elaborated.
Fig. 3 is the X-X line sectional schematic diagram of Fig. 1 under the heat insulation structural of the present invention the 1st embodiment.As shown in the figure, the refrigerator case thermal insulation structure of the present invention the 1st embodiment includes: the enclosure 10 that can bear the high strength steel formation of external impact, the outcase of refrigerator inner face 120 that mixes small hollow sphere powder and ABS resin postforming is in order to improve refrigeration, freezing efficiency, be provided with the frothing foam 30 that forms with polyurethane foam agent foaming between enclosure 10 and shell inner face 120.
Outcase of refrigerator inner face 120 is behind the heat-proof quality outstanding small hollow sphere powder and ABS plastic mixed with resin, by the processing that is shaped, makes.
The granular size of small hollow sphere under the situation that does not reduce ABS resin intensity, improves effect of heat insulation less than 100 μ m.Small hollow sphere is white silica (SiO by principal component
2) ceramic series material form, under 1500 ℃～2000 ℃ temperature conditions, can keep stable state.This is that small hollow sphere need bear this temperature effect owing to produce high-temperature high-pressure state in the process of formation frothing foam 30.
In outcase of refrigerator inner face 120, add small hollow sphere with effect of heat insulation, can use the frothing foam 30 of its amplitude B less than traditional amplitude A, also can form the more outstanding refrigerator case thermal insulation structure of effect of heat insulation.This means the thickness of the heat insulation structural that can reduce outcase of refrigerator, can allow the identical refrigerator of shell size have bigger volume.
Fig. 4 is the X-X line sectional schematic diagram of Fig. 1 under the heat insulation structural of the present invention the 2nd embodiment.The refrigerator case thermal insulation structure of the present invention the 2nd embodiment includes: the outcase of refrigerator outside 10 that can bear the high strength steel formation of external impact, by ABS resin form, inboard face be coated be equipped with comprise small hollow sphere powder be coated with feed liquid 120 ' outcase of refrigerator inner face 20, for improve refrigeration, freezing efficiency, between outcase of refrigerator outside 10 and outcase of refrigerator inner face 20, the frothing foam 30 that forms with polyurethane foam agent foaming.
Be coated with feed liquid 120 ' in the small hollow sphere particles of powder size that contains less than 100 μ m, have the performance that under 1500 ℃～2000 ℃ temperature conditions, can keep stable state.Be coated with that feed liquid 120 ' be is mixed small hollow sphere powder with 1: 5 to 1: 10 weight rate and polyurethane series coating forms.The small hollow sphere powder that contains good heat-insulation effect be coated with feed liquid 120 ', be coated with cased 20 inboard face, can obtain the better refrigerator case thermal insulation structure of effect of heat insulation.Compare with the conventional refrigerator case thermal insulation structure of Fig. 2, the refrigerator case thermal insulation structure of the present invention the 2nd embodiment has under the situation of same effect of heat insulation, and the thickness C of its frothing foam 30 is less than original thickness A.
Fig. 5 is the X-X line sectional schematic diagram of Fig. 1 under the heat insulation structural of the present invention the 3rd embodiment
As shown in Figure 5, refrigerator case thermal insulation structure can also include: outcase of refrigerator outside 10 and outcase of refrigerator inner face 20, and between outcase of refrigerator outside 10 and outcase of refrigerator inner face 20, frothing foam 30 with polyurethane foam agent foaming formation, and on the inboard face of outcase of refrigerator outside 10, be coated be equipped with the 2nd embodiment be coated with feed liquid 120 ' identical be coated with feed liquid 110 ', to improve the effect of heat insulation of outcase of refrigerator.
Refrigerator case thermal insulation structure of the present invention can be widely used in the various refrigerators such as kraut refrigerator refrigerating chamber or refrigerating chamber.Be to be example above, be illustrated with most preferred embodiment of the present invention.But scope of the present invention is not subject to specific embodiment, can carry out suitable change in right request scope.
