DETAILED DESCRIPTION
[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.
[0026] As shown in Figure 1 , Figure 2 and Figure 3 , as an implementation manner, the present application provides a phase change box for wrapping a memory 1, so as to protect the memory 1, while maintaining the working temperature of the memory 1.
[0027] The phase change box comprises a first cavity 2 and a second cavity 3, the first cavity 2 is used for containing a phase change material, and the second cavity 3 is used for containing the memory 1, the second cavity 3 is located in the first cavity 2, so as to wrap the memory 1 in the phase change material, and maintain the working temperature of the memory 1 through the state change of the phase change material.
[0028] It should be noted that the phase change material is a material capable of undergoing a physical state change at a specific temperature. The phase change material can be paraffin or the like.
[0029] In order to facilitate the wire harness of the memory 1 to extend out of the phase change box, the second cavity 3 is formed with a first opening 301, and the wire harness of the memory 1 extends out of the phase change box through the first opening 301.
[0030] The phase change box is formed with a pressure relief part 4, the pressure relief part 4 is located in the first cavity 2, and in a normal state, the pressure relief part 4 is in a closed state, preventing the pressure relief part 4 from affecting the sealing performance of the first cavity 2, so as to prevent the phase change box from drying and losing the protection effect.
[0031] When the pressure inside the first cavity 2 increases, the pressure relief section 4 ruptures, thereby facilitating the pressure relief of the first cavity 2.
[0032] The first cavity 2 has a corner portion 201, which is spaced apart from the second cavity 3. That is, there is a certain distance between the corner portion 201 and the second cavity 3. The pressure relief portion 4 is located at the corner portion 201, so that there is a certain distance between the pressure relief portion 4 and the second cavity 3. This prevents the phase change material from depressurizing towards the memory 1 after the pressure relief portion 4 breaks, thereby improving the protection performance of the phase change box for the memory 1.
[0033] By setting the pressure relief part 4 at the corner part 201, when the pressure inside the phase change box increases, it is ensured that the pressure relief part 4 can rupture stably, thereby improving the stability of the pressure relief of the phase change box.

[0036] like Figure 2 and Figure 3 As shown, in one implementation, the phase change box includes multiple box plates 5, which are connected to each other to form a first cavity 2.

[0038] In this implementation, the phase change box includes four side wall boxes 501 and one end box 502. The four side wall boxes 501 are perpendicular to each other and connected to form a U-shaped structure. The end box 502 is connected to one end of the U-shaped structure and seals that end.
[0039] The corner 201 can be the connection point of adjacent side wall panels 501, or the connection point of side wall panel 501 and end panel 502.
[0040] As one implementation method, along the extension direction of the corner portion 201, the length of the pressure relief portion 4 is no more than one-fifth of the length of the corner portion 201, ensuring that the pressure relief portion 4 can stably relieve pressure while improving the connection strength of adjacent box plates 5, thereby improving the overall strength of the phase change box.
[0041] As an implementation manner, the pressure relief part 4 is formed at the connection between two adjacent side wall box plates 501 and the end box plate 502, that is, the pressure relief part 4 is formed at the sharp corner position of the phase change box.

[0043] Specifically, in the wall thickness direction of the box plate 5, the depth of the groove 401 is less than or equal to half of the wall thickness of the box plate 5. By arranging the groove 401 in the first cavity 2, a weak area is formed in the phase change box, so as to facilitate the rupture of the groove 401 and realize the pressure relief of the phase change box.
[0044] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , as an implementation manner, the phase change box includes a phase change box body 6, a mounting box 7 and an end cover 8, the mounting box 7 is arranged in the phase change box body 6, the end cover 8 is arranged at one end of the phase change box body 6, the inner wall of the phase change box body 6, the inner wall of the end cover 8 and the outer wall of the mounting box 7 form the first cavity 2, and the second cavity 3 is formed in the mounting box 7.
[0045] The phase change box body 6 has a second opening 601, and the second opening 601 and the first opening 301 are respectively located on two opposite faces of the phase change box body 6. The end cover 8 seals the second opening 601.

[0062] Specifically, the first segment 1002 is located outside the phase change box, and the second segment 1004 is located inside the first cavity 2.
[0063] As an implementation manner, the sealing plug 10 is formed with a first hole 1001 at the end portion facing the first cavity 2, and the first hole 1001 is located inside the first cavity 2.
