Description

Technical Field

[0001] The utility model relates to the technical field of dry refrigerators, and more specifically, to a high-performance dry refrigerator based on a vacuum insulation panel. Background Art

[0002] In recent years, the logistics industry has gradually increased its requirements for cold chain insulation, and the requirements and standards have gradually improved. The logistics demand for temperature-sensitive goods has increased rapidly. Dry ice boxes are widely used in the cold chain packaging field due to their simple structure and less influence by geographical location. Dry ice is a commonly used refrigerant with a stable temperature of -78.5°C during sublimation. It is often used for transportation and insulation of medicines, reagents, bioactive substances, or frozen foods.

[0003] When using foam boxes as insulation materials, the evaporation rate of dry ice is too fast and the insulation time is short. Therefore, vacuum insulation panels are sometimes used to make dry ice boxes. However, Figure 3 and Figure 4 As shown, traditional dry refrigerators are usually single-layer vacuum insulation panel structures, mainly composed of a box body 1, an inner cavity 2 and a cover body 3. Since the heat flow generated when the refrigerant in the inner cavity 2 of the box body 1 undergoes phase change has a short path for transferring energy to the outside of the box, the dry refrigerator has poor insulation time, affecting the utilization rate of the cold source. In addition, the insulation performance will quickly decay after the vacuum insulation panel is damaged and leaks, affecting the transportation and storage effect of the goods. In view of this, we propose a high-performance dry refrigerator based on vacuum insulation panels to solve the above problems. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a high-performance dry refrigerator based on a vacuum insulation panel to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A high-performance dry refrigerator based on vacuum insulation panels comprises an inner box, an outer box and a box cover, wherein the box cover is arranged on the outer box, and the inner box is fixedly installed in the outer box. The inner box is composed of five inner interlayer insulation panels, and the outer box is composed of five outer interlayer insulation panels. A storage cavity is formed inside the inner box, and an interlayer outer cavity with a certain air gap is formed between the outside of the inner box and the inside of the outer box.

[0007] As a preferred technical solution of the present invention, the box cover includes a first box cover and a second box cover, the second box cover is fixedly mounted on the upper end of the first box cover, and the first box cover is slidably embedded in the inner box body.

[0008] As a preferred technical solution of the present utility model, the cross-sectional area size of the second box cover is larger than that of the first box cover.

[0009] As a preferred technical solution of the present utility model, the inner insulation board, the outer insulation board, the first box cover and the second box cover are all components made of vacuum insulation panels.

[0010] As a preferred technical solution of the present utility model, fabric fixing parts are fixedly installed on the outer side of the outer box body and the top of the second box cover.

[0011] As a preferred technical solution of the present utility model, the thickness dimensions of the inner box body and the outer box body are both 5 mm - 40 mm, and the thickness dimension of the outer cavity of the sandwich is 0.5 mm - 2 mm.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, the inner box body is fixedly installed inside the outer box body. The inner box body is composed of five inner insulation boards combined, and the outer box body is composed of five outer insulation boards combined. A storage inner cavity is formed inside the inner box body, and goods can be loaded into the storage inner cavity of the inner box body. A sandwich outer cavity with a certain air gap is formed between the outside of the inner box body and the inside of the outer box body. Utilizing the sandwich outer cavity is beneficial to extending the path for the heat generated during the phase change of the refrigerant to transfer energy to the outside of the box body, thereby improving the heat preservation aging effect of the dry ice box and improving the utilization rate of the cold source. The heat preservation performance can be improved without increasing the outer volume and without reducing the loading volume. Through the multi-layer structure formed by the inner box body, the sandwich outer cavity and the outer box body arranged in sequence from the inside to the outside, if a certain layer of vacuum insulation panel leaks air, the loss ratio of the heat preservation performance can be effectively reduced, which is convenient for ensuring the transportation and storage effects of goods.

[0014] 2. In the present utility model, by providing the first box cover and the second box cover, the second box cover is fixedly installed at the upper end of the first box cover, and the first box cover is slidably embedded in the inner box body, so that the first box cover can achieve a good sealing effect on the inner box body. The cross-sectional area size of the second box cover is larger than that of the first box cover, and the second box cover seals the port on the outer box body, thereby ensuring the overall sealing effect of the dry ice box.

[0026] Embodiment 1:

[0027] As Figures 1 to 2As shown in the figure, the present utility model provides a high-performance dry refrigerator based on a vacuum insulation panel, which includes an inner box body 101, an outer box body 102 and a box cover. The box cover is arranged on the outer box body 102, and the inner box body 101 is fixedly installed inside the outer box body 102. The inner box body 101 is composed of five inner partition insulation panels, and the outer box body 102 is composed of five outer partition insulation panels. A storage inner cavity 201 is formed inside the inner box body 101, and goods can be loaded into the storage inner cavity 201 of the inner box body 101. A sandwich outer cavity 202 with a certain air gap is formed between the outside of the inner box body 101 and the inside of the outer box body 102. Utilizing the sandwich outer cavity 202 is beneficial to extending the path for the heat generated when the refrigerant undergoes a phase change to transfer energy to the outside of the box body, thereby improving the heat preservation time limit of the dry refrigerator. Through the cooperation of the inner box body 101, the sandwich outer cavity 202 and the outer box body 102, which are distributed in sequence from the inside to the outside, to form a multi-layer structure. If a certain layer of the vacuum insulation panel leaks air, the loss ratio of the heat preservation performance can be effectively reduced.

[0028] Among them, as Figure 1 shown, the box cover includes a first box cover 301 and a second box cover 302. The second box cover 302 is fixedly installed at the upper end of the first box cover 301. The first box cover 301 is slidably embedded in the inner box body 101, so that the first box cover 301 can achieve a good sealing effect on the inner box body 101. The cross-sectional area size of the second box cover 302 is larger than the cross-sectional area size of the first box cover 301. The second box cover 302 seals the port on the outer box body 102, thereby ensuring the overall sealing effect of the dry refrigerator.

[0029] Among them, as Figure 1 shown, the inner partition insulation panel, the outer partition insulation panel, the first box cover 301 and the second box cover 302 are all components made of a vacuum insulation panel.

[0030] Among them, as Figure 1 shown, fabric fixing parts 401 are fixedly installed on the outside of the outer box body 102 and the top of the second box cover 302. A fabric belt can be used to connect the two fabric fixing parts 401, thereby playing a role in strengthening the stability of the second box cover 302 on the outer box body 102.

[0031] Among them, as Figure 2 shown, the thickness dimensions of both the inner box body 101 and the outer box body 102 are 5 mm - 40 mm, and the preferred dimension is 19 mm. The thickness dimension of the sandwich outer cavity 202 is 0.5 mm - 2 mm, and the preferred dimension is 2 mm. The length, width and height of the storage inner cavity 201 are 205 mm, 205 mm and 205 mm respectively.

[0032] Comparative Example 1:

[0033] A small-sized dry refrigerator is composed of six vacuum insulation panels, each with a thickness of 40 mm. The inner diameter of the small-sized dry refrigerator has a length of 205 mm, a width of 205 mm, and a height of 205 mm. Four side panels are spliced in a clockwise zigzag pattern.

[0034] Example 2:

[0035] The difference from the above Example 1 is that the length of the storage inner cavity 201 is 430 mm, the width is 355 mm, and the height is 355 mm.

[0036] Comparative Example 2:

[0037] A large-sized dry refrigerator is composed of six vacuum insulation panels, each with a thickness of 40 mm. The inner diameter of the large-sized dry refrigerator has a length of 430 mm, a width of 355 mm, and a height of 355 mm. Four side panels are spliced in a clockwise zigzag pattern.

[0038] As Figures 4 - 8 shown, by comparing Example 1 with Comparative Example 1, and Example 2 with Comparative Example 2, through two groups of comparative experiments, it can be seen that the heat preservation performance of the dry refrigerators in Example 1 and Example 2 is significantly higher than that of Comparative Example 1 and Comparative Example 2 of the same size specification respectively. The heat preservation time limit is increased by about 5% - 10%, and the dry ice consumption rate is also about 5% - 10% lower. The dry refrigerators in Example 1 and Example 2 can improve the heat preservation performance without increasing the outer volume and without reducing the loading volume.
