Abstract
A polyurethane + VIP vacuum insulated commercial freezer cabinet comprising: the vacuum heat insulation cabinet comprises an in-cabinet foaming plate, an out-cabinet foaming plate, an end wood plate, a VIP vacuum heat insulation plate and polyurethane foaming liquid. When the vacuum heat insulation board is actually used, glue is attached to the back of the VIP vacuum heat insulation board and is adhered to the inner side of the foaming board outside the cabinet, after the sticking and the pressing, the sealing is done by using an adhesive tape, the combined structure of the foaming board outside the cabinet, which is adhered with the VIP vacuum heat insulation board, is combined and fixed with the foaming board inside the cabinet and the end wood board, and finally the combined structure is placed into polyurethane foaming equipment, and polyurethane liquid is injected for foaming. This polyurethane + VIP vacuum insulation panel commercial freezer cabinet was completed. By adding the VIP vacuum thermal insulation board on the polyurethane foaming thermal insulation box body, the thermal insulation effect of the refrigeration and freezing showcase body is better, and the practical purposes of energy conservation and consumption reduction are achieved. The material cost is also reduced on the raw material. And the service life of the whole machine of the product is prolonged.
Description
Technical Field
The utility model relates to a commercial supermarket show case, a plurality of fields such as commercial kitchen and low temperature commodity circulation are a commercial freezer box structure of polyurethane + VIP vacuum heat insulating board of using on commercial refrigeration product.
Background
At present, commercial supermarket showcase insulation boxes in China are of polyurethane foam structures, and the boxes are thick. The refrigerating and freezing box body of the supermarket display cabinet has small effective volume and high energy consumption. The vacuum insulation panel (VIP panel for short) is one of vacuum insulation materials, has the characteristics of greatly reduced heat conductivity coefficient, environmental protection, high efficiency and energy conservation, and is the most advanced high-efficiency insulation material in the world at present. The application of polyurethane + VIP vacuum insulation panels to commercial freezer cases is an important issue to be studied for practical use in the field.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims at providing a commercial freezer box of polyurethane + VIP vacuum insulation board, such box structure has promoted commercial supermarket show case, the freezer box thermal-insulated heat retaining performance of kitchen cabinet and low temperature commodity circulation product greatly.
The technical scheme is as follows: the utility model relates to a commercial freezer box of polyurethane + VIP vacuum insulation board, it includes: the refrigerator comprises an inner foaming plate, an outer foaming plate, an end wood plate, a VIP vacuum heat insulation plate and polyurethane foaming liquid, wherein the VIP vacuum heat insulation plate is added in a foaming body of a commercial refrigerator box body, under the condition of the refrigerator box body with the same thickness, the heat conductivity coefficient of the VIP vacuum heat insulation plate is less than 0.005W/m.K and is only 1/4-1/5 of the polyurethane foaming plate, the density is 3-8 times of that of polyurethane foaming, and the refrigerator has excellent heat insulation performance. The supermarket showcase refrigerator body needs a certain bearing effect, so that a heat insulation and preservation box body structure in the form of polyurethane and VIP vacuum heat insulation plates needs to be used; the method is characterized in that glue is attached to the back of the VIP vacuum thermal insulation board, the VIP vacuum thermal insulation board is adhered to the inner side of an outer foaming board of a cabinet, sealing is carried out by using an adhesive tape after the sticking and the pressing are carried out, the outer foaming board combined structure adhered with the VIP vacuum thermal insulation board is combined and fixed with an inner foaming board of the cabinet and an end wood board, and finally the outer foaming board combined structure is placed into polyurethane foaming equipment and injected with polyurethane foaming liquid for foaming. This formed a commercial freezer cabinet of polyurethane + VIP vacuum insulation panels.
The beneficial results are that: the utility model discloses an on polyurethane foam's thermal-insulated insulation box, increase VIP vacuum heat insulating board, make commercial freezer box's thermal-insulated heat preservation effect better, accomplished energy saving and consumption reduction's practical purpose. The cost of the raw materials is reduced, and the service life of the whole machine of the product is prolonged.
Description of the drawings: FIG. 1 is a partial cross-sectional view of a commercial freezer housing incorporating polyurethane + VIP vacuum insulation panels;
FIG. 2 is a front view of a commercial freezer housing of polyurethane + VIP vacuum insulation panels;
FIG. 3 is a partial cross-sectional view of a commercial freezer housing made of polyurethane foam board;
FIG. 4 is a front view of a commercial freezer cabinet with polyurethane foam boards;
in the figure: the cabinet comprises an inner foaming plate 1, an outer foaming plate 2, an end wood plate 3, a VIP vacuum heat insulation plate 4 and polyurethane foaming liquid 5.
Detailed Description
As shown in figure 1 and figure 2, the utility model relates to a commercial freezer box of polyurethane + VIP vacuum heat insulating board, its major component part is foaming board 1 in the cabinet, foaming board 2 outside the cabinet, end plank 3, VIP vacuum heat insulating board 4, polyurethane foaming liquid 5. When the vacuum heat insulation cabinet is actually used, the VIP vacuum heat insulation plate is firstly adhered to the inner side of the foaming plate outside the cabinet by the adhesive tape, and then the sealing is done by the adhesive tape after the adhesion and the compaction, and the embedded part mounting holes on the foaming plate are avoided; then, fixing two end boards at two ends of the foaming board in the cabinet and the foaming board outside the cabinet respectively; finally, the box body adhered with the VIP vacuum thermal insulation board is placed into foaming equipment, foaming liquid is injected into the foaming equipment, and a commercial refrigerator box body of polyurethane and the VIP vacuum thermal insulation board is formed; the commercial refrigerator box body of the polyurethane and VIP vacuum thermal insulation board has particularly good thermal insulation effect. And displaying according to the performance detection result: the commercial freezer cabinet with polyurethane + VIP vacuum insulation panels had a very low thermal conductivity, 2/3 lower than the thermal conductivity of the freezer cabinet with polyurethane foam. The thickness of the box body plate can be thinned according to market demands, the inner volume of the refrigeration equipment is improved, and the energy efficiency is improved.
The embodiments in the present description are described in a progressive manner, and each embodiment focuses on differences from other embodiments, and similar parts between the embodiments may be mutually joined.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
