Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0028] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0029] In the prior art, vacuum VIP panels with glass fiber core materials cannot be directly spliced ​​due to uneven edges, and generally require composite foaming to achieve good air tightness. To this end, the present application proposes a heat insulation component to solve the technical problem that vacuum panels in the prior art cannot be directly spliced ​​due to uneven edges.

[0030] like Figure 1 As shown, the embodiment of the present application provides a thermal insulation assembly 10, comprising:

[0031] A first vacuum plate 100, wherein the first vacuum plate 100 extends along a first direction;

[0032] A second vacuum plate 200 extending along a second direction; and

[0033] The foamed porous structure 300 has two opposite sides that are in close contact with the first vacuum plate 100 and the second vacuum plate 200 respectively; the foamed porous structure 300 fills the gap between the first vacuum plate 100 and the second vacuum plate 200 to prevent gas from flowing in the gap between the two; the foamed porous structure 300 is in a compressed state when subjected to an external force, and its compression rate is at least 80%.

[0034] In the technical solution of the present application, the foamed porous structure 300 can be a composite of one or more of foamed POM, foamed polyetherimide (PEI), foamed polyphenylene sulfide (PPS), foamed polyarylether nitrile (PEN), foamed PPO, foamed PPS, foamed PEEK, foamed CPE, and slow-rebound foamed polyurethane. The foamed porous structure 300 has good air tightness. Although it is a porous material, the pores are not connected, which can block the convection of the space to achieve a good thermal insulation effect.

[0035] In the embodiment of the present application, the first vacuum plate 100 and the second vacuum plate 200 are connected by a foamed porous structure 300 in a compressed state, so that even if there is unevenness, the connection gap between the two can be filled with the foamed porous structure 300 with good air tightness and high compression rate, and the foamed porous structure 300 has good air tightness after compression, thereby preventing air from forming air convection in the gap between the two, thereby improving the thermal insulation effect.

[0036] It should be noted that the angle between the first direction and the second direction is arbitrary. For example, the first direction and the second direction are parallel, and the foamed porous structure 300 is filled between the ends of the first vacuum plate and the second vacuum plate. For another example, the first direction and the second direction are non-parallel, and the surface of the first vacuum plate and the end of the second vacuum plate are filled with the foamed porous structure 300. That is: in the embodiment, the first vacuum plate and the second vacuum plate are placed at any angle, and the gap between the two can be filled by the foamed porous structure 300 to increase the application range and scenarios of vacuum plate insulation.

[0037] As an optional implementation of the above embodiment, when the foamed porous structure 300 is in a compressed state, the thickness of the foamed porous structure 300 is between 2 mm and 3 mm; when the foamed porous structure 300 is in an initial state, the thickness of the foamed porous structure 300 is between 8 mm and 12 mm. In this embodiment, the foamed porous structure 300 has a good compression rate, and its compression rate can be as high as 80% or more. The thickness of the foamed porous structure 300 after compression can be 2 mm, 2.5 mm or 3 mm. The thickness of the foamed porous structure 300 when it is not compressed and in the original state is 8 mm, 9 mm, 10 mm, 11 mm or 12 mm. In general, the thickness of the foamed porous structure 300 after compression is 2.5 mm, and the thickness of the foamed porous structure 300 when it is not compressed and in the original state is 10 mm.

[0038] As an optional implementation of the above embodiment, the foamed porous structure 300 is respectively attached to the first vacuum plate 100 and the second vacuum plate 200 at two opposite sides in the thickness direction. In the embodiment of the present application, the foamed porous structure 300 is provided with adhesive so that it can be attached to the first vacuum plate 100 and the second vacuum plate 200.

[0039] As an optional implementation of the above embodiment, Figure 1 and Figure 2As shown, the first vacuum panel 100 has a surface 110 in the thickness direction, and the foamed porous structure 300 is arranged on the surface 110; the thickness direction is arranged perpendicular to the first direction. In an embodiment, the foamed porous structure 300 is arranged on the surface 110 of the first vacuum panel 100, and then the second vacuum panel 200 is pasted on the foamed porous structure 300.

[0040] As an optional implementation of the above embodiment, the second direction is the normal direction of the surface 110. That is, in the embodiment, the first vacuum plate 100 and the second vacuum plate 200 are vertically arranged.

[0041] As an optional implementation of the above embodiment, the foamed porous structure 300 is arranged at the edge of the surface 110. The foamed porous structure 300 is arranged around the first vacuum panel 100. When applied to the box body 20, the second vacuum panel 200 also needs to be enclosed to form a cavity. For this reason, in the embodiment, the foamed porous structure 300 is arranged at the edge of the surface 110 and around the first vacuum panel 100, so that the second vacuum panels 200 around can be spliced ​​with the first vacuum panel 100, so as to improve the stability and heat dissipation effect of the thermal insulation assembly 10.

[0042] As an optional implementation of the above embodiment, the width of the foamed porous structure 300 when in a compressed state is greater than the thickness of the second vacuum panel 200. Generally, the width of the foamed porous structure 300 is substantially consistent with the thickness of the second vacuum panel 200 when in a normal state. The foamed porous structure 300 is deformed when under pressure and its width is greater than the thickness of the second vacuum panel 200, so as to improve the heat insulation effect.

[0043] As an optional implementation of the above embodiment, Figure 1 and Figure 3 As shown, the second vacuum panel 200 has a peripheral side surface 210, and the peripheral side surface 210 is the side surface of the second vacuum panel 200 in the second direction; the foamed porous structure 300 is arranged on the peripheral side surface 210. When applied to the box body 20, the second vacuum panel 200 also needs to be enclosed to form a cavity. For this reason, in the embodiment, the foamed porous structure 300 is arranged on the peripheral side surface 210, so that the second vacuum panel 200 can be spliced ​​with the first vacuum panel 100 and can also be spliced ​​with other second vacuum panels 200, so as to improve the stability and heat dissipation effect of the thermal insulation assembly 10.

[0044] Combination Figure 4 and Figure 5As shown, the present application also proposes a thermostatic box, including a box body 20 and a heat insulation component 10. The heat insulation component 10 adopts part of the technical solutions or all of the technical solutions in the aforementioned embodiments, so that the thermostatic box has a good heat insulation effect. The box body 20 has an embedding groove; the heat insulation component 10 is arranged in the embedding groove so that the foamed porous structure 300 is in a compressed state. In an embodiment, the box body 20 includes an inner box and an outer box. The inner box and the outer box are spaced apart to define an embedding groove, and the heat insulation component 10 is arranged in the embedding groove. And according to the size design, after the heat insulation component 10 is placed in the embedding groove, a certain pressure is applied to the porous foam structure and it is in a compressed state, so that air convection will not occur in the gap between the first vacuum plate 100 and the second vacuum plate 200, thereby improving the heat insulation effect.

[0045] As an optional implementation of the above embodiment, the embedding groove includes a first embedding groove and a second embedding groove that are connected; the first vacuum panel 100 is arranged in the first embedding groove, and the second vacuum panel 200 is arranged in the second embedding groove. The length of the first embedding groove in the first direction is less than the sum of the length of the first vacuum panel 100 in the first direction, the thickness of the second vacuum panel 200 in the first direction, and the original thickness of the foamed porous structure 300; or the length of the second embedding groove in the second direction is less than the sum of the thickness of the first vacuum panel 100 in the second direction, the length of the first vacuum panel 100 in the second direction, and the original thickness of the foamed porous structure 300. In this way, after the heat insulation component 10 is arranged in the embedding groove, the porous foam structure is compressed due to the relative relationship of the sizes.

[0046] The above is a detailed introduction to an insulation component and a constant temperature box provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea; at the same time, for technical personnel in this field, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
