The support member 205 is provided between the core material 201 and the coating material 202. Typically, the cover material 202 encapsulates the core 201 and the support 205 in a bag-like form. Both ends of the bag-shaped film material 202 are sealed by a sealing device 204. A commonly used film-covering material 202 is a multi-layer structure, for example, with the outermost layer being a strength material (e.g., a nylon layer), the next outer layer being a protective film material (e.g., PET), the next outer layer being a barrier material (e.g., aluminum or aluminum foil), and the innermost layer being a hot melt fused layer (e.g., PE). A getter 203 may be further provided in the core 201. As shown in fig. 2, the support 205 has a flat plate portion 251 and at least two convex portions 252. The outer side surface of the flat plate portion 251 is bonded to the coating material 202, and the inner side surface of the flat plate portion 251 is protruded toward the core material 201 to form a protrusion 252. That is, the support member 205 on the side where the cover material 202 is attached is a planar structure, and the support member 205 on the side where the core material 201 is attached is a concave-convex structure. The vacuum insulation panel 200 of the embodiment of the present invention is provided with the supporting member 205 having the flat plate portion 251 and at least two protrusions 252 between the core material 201 and the film coating material 202, and the outer side surface of the flat plate portion 251 is attached to the film coating material 202, and the protrusions 252 are formed on the inner side surface of the flat plate portion 251, so that the structure of the core material 201 is not very compact, and the vacuum pumping is easy to be performed, thereby the vacuum insulation panel 200 can reach a lower vacuum degree; meanwhile, the core material 201 cannot directly pierce the film coating material 202 due to the protection of the flat plate part 251, so that the film coating material 202 is prevented from being pierced or stretched due to the reduction of vacuum pressure in the vacuum pumping process; in addition, the planar structure of the supporting member 205 faces the film coating material 202, so that the surface unevenness of the existing vacuum insulation panel 200 can be greatly improved, and the problem that the outer shell of the refrigerator 100 is easily uneven after the vacuum insulation panel 200 is attached and foamed in the refrigerator 100 can be solved by changing the surface state of the vacuum insulation panel 200.

The groove 264 may be, for example, of arcuate cross-section. In other embodiments, the first protection portion 261, the second protection portion 262, and the third protection portion 263 are perpendicular to each other, and the size of the corner protector 206 is slightly smaller than the size of the corner of the film covering material 202, so that the corner protector 206 is clamped on the corner of the film covering material 202. The vacuum insulation panel 200 is substantially rectangular parallelepiped, and the first protection portion 261, the second protection portion 262, and the third protection portion 263 of the corner protector 206 are perpendicular to each other so that the corner protector 206 is more matched with the corner of the film material 202. When the corner protector 206 is applied to the outside of the corner of the film covering material 202 and/or the core material 201, the size of the corner protector 206 may not be specifically limited, and the film covering material 202 may be prevented from being damaged, while considering the difficulty of installation, the stability of installation, the production cost, and the like of the corner protector 206. When the corner protector 206 is applied to the outside of the corner of the core 201, it is preferable that the corner protector 206 and the support 205 are fitted to each other to completely cover the core 201.
