Abstract
The utility model discloses a kind of vacuum heat-insulation refrigerator, comprise casing, evaporimeter, condenser and refrigeration unit, casing is made up of vacuum insulation panel, vacuum insulation panel comprises inwall, outer wall, support frame and vacuum exhaust pipe, support frame is located between inwall and outer wall, inwall and outer wall integrally closed form cavity, and cavity is in communication with the outside by vacuum exhaust pipe, and vacuum exhaust pipe is located at vacuum heat-insulation panel edges.The utility model decreases the insulation thickness of refrigerator, improves heat insulation effect, all has positive role for reducing material, reduction energy consumption, the charging ratio improving transport, reduction production and transport cost etc.
Description
Technical field
The utility model relates to Compressing Refrigeration field, specifically a kind of refrigerator.
Background technology
Current refrigerator thermal insulation layer adopts frothing foam to fill.The coefficient of overall heat transmission of foam is 0.02w/mk, although very low, also has certain loss.Thus, in order to be incubated, heat-insulation layer all does very thick.But so also can bring the problem reducing refrigerator actual volume.Such as, a external form cross section is the refrigerator of 600 × 600cm, and removing four limit thickness is the heat-insulation layer of 60cm, and actual volume sectional area is 64% of external form.
Summary of the invention
Technical problem to be solved in the utility model is to propose the vacuum heat-insulation refrigerator that a kind of energy-saving heat preserving is effective, actual volume large, production and transport cost is low.
For solving the problems of the technologies described above, a kind of vacuum heat-insulation refrigerator of the utility model comprises casing, evaporimeter, condenser and refrigeration unit, described casing is made up of vacuum insulation panel, described vacuum insulation panel comprises inwall, outer wall, support frame and vacuum exhaust pipe, described support frame is located between described inwall and outer wall, described inwall and outer wall integrally closed form cavity, and described cavity is in communication with the outside by vacuum exhaust pipe, and described vacuum exhaust pipe is located at described vacuum heat-insulation panel edges.
Above-mentioned a kind of vacuum heat-insulation refrigerator, described evaporimeter is located on described inwall, and the outside of described outer wall is located at by described condenser, and described refrigeration unit is located at described lower box.
See that the thermal conductivity factor of vacuum is 0 theoretically.The utility model is owing to have employed above-mentioned technical pattern, and it has the following advantages: 1, the heat-insulation layer of refrigerator is substituted existing foam by vacuum by it, decreases the insulation thickness of refrigerator, promotes heat insulation effect.Same profile, the actual volume of refrigerator increases; And same volume, the profile of refrigerator will reduce greatly, and this has very positive meaning for minimizing material, reduction energy consumption, the charging ratio improving transport, reduction production and transport cost.2, utilize the operation that in refrigerator production process, compressor vacuumizes, refrigerator vacuum insulation panel is vacuumized, after exhausting vacuum, use compressor copper pipe sealing machine to seal described vacuum exhaust pipe, need not new equipment be increased, decrease foamed process.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model vacuum heat-insulation refrigerator;
Fig. 2 is the structural representation of vacuum insulation panel in Fig. 1.
Detailed description of the invention
As shown in Figure 1, the utility model vacuum heat-insulation refrigerator comprises casing 1, evaporimeter 5, condenser 6 and refrigeration unit 9.Shown in Fig. 2, casing 1 is made up of vacuum insulation panel 11, and vacuum insulation panel 11 comprises inwall 2, outer wall 4, support frame 3 and vacuum exhaust pipe 8, and support frame 3 is located between inwall 2 and outer wall 4, to restrict the atmospheric pressure effect that vacuum heat-insulating layer is subject to.Inwall 2 and outer wall 4 integrally closed form cavity 7, and vacuum exhaust pipe 8 is arranged on the marginal position of vacuum insulation panel 11, and cavity 7 is in communication with the outside by vacuum exhaust pipe 8.Evaporimeter 5 is located on inwall 2, and condenser 6 is placed in the outside of outer wall 4, and refrigeration unit 9 is arranged at the bottom of casing 1.
Because the heat-insulating property of vacuum layer is determined by the thermal conductivity factor of supporter and the area of the strong point, thus select supporter and less supporting surface that thermal conductivity factor is little, energy-saving effect can be played better.
