However, if the thermal conductive gel is too thick, it will affect the heat dissipation effect of the refrigerator, resulting in a decrease in the cooling performance and service life of the refrigerator.

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0035] Please refer to the following Figures 1 to 4 A refrigerator installation box 1 , a refrigerator assembly and a vehicle according to an embodiment of the utility model are described.

[0036] like Figures 1 to 4 As shown, the refrigerator installation box 1 according to the embodiment of the utility model includes: a fixed bracket 11, a shell 12 and a heat sink 13. The fixed bracket 11 is connected to the shell 12 and encloses a mounting cavity 14. The heat sink 13 is arranged in the mounting cavity 14. The refrigerator 2 is suitable for being installed in the mounting cavity 14 and fitting with the heat sink 13. The fixed bracket 11 can be squeezed and deformed to make the mounting cavity 14 adapt to the refrigerator 2.

[0037] According to the refrigerator installation box 1 of the embodiment of the utility model, the refrigerator 2 can be installed in the installation cavity 14 and dissipate heat through the heat sink 13. Since the fixing bracket 11 can be squeezed and deformed, when the installation tolerance between the refrigerator 2 and the installation cavity 14 is large, the shape of the fixing bracket 11 can be changed to make the inner wall of the installation cavity 14 fit better with the refrigerator 2, thereby reducing the contact thermal resistance of the refrigerator 2 and improving the heat dissipation effect of the refrigerator 2.

[0038] It should be noted that the fixing bracket 11 can be a structural member that can be flexibly deformed, or a structural member that can be elastically deformed. It is understandable that the fixing bracket 11 can absorb the installation tolerance between the refrigerator 2 and the fixing bracket 11 by deformation, so that the refrigerator 2, the shell 12 and the fixing bracket 11 can be in close contact with each other, and the flexible or elastic fixing bracket 11 can avoid excessive squeezing of the refrigerator 2, which is beneficial to protecting the refrigerator 2 itself and extending the service life of the refrigerator 2.

[0039] In some embodiments, Figure 3 and Figure 4 As shown, the fixed bracket 11 includes a bracket body 111 and an ear seat 112, the ear seat 112 is arranged on the outer periphery of the bracket body 111, the ear seat 112 is connected to the shell 12, one side of the heat sink 13 is in contact with the bracket body 111, and the other side of the heat sink 13 is suitable for contacting with the refrigerator 2. For example, the ear seat 112 includes a first ear seat 1121 and a second ear seat 1122, and the first ear seat 1121 and the second ear seat 1122 are respectively arranged on both sides of the bracket body 111. It can be understood that the bracket body 111 is fixed to the shell 12 through the two ear seats 112, and the bracket body 111 and the shell 12 enclose a mounting cavity 14.

[0040] Optionally, at least one of the fixing bracket 11 and the ear seat 112 is an extrudable and deformable structural member. In an embodiment of the utility model, the fixing bracket 11 and the ear seat 112 are both extrudable and deformable structural members. In one example, the fixing bracket 11 and the ear seat 112 are both flexible members. For example, the fixing bracket 11 and the ear seat 112 are both flexible plastic members. The deformation of the flexible fixing bracket 11 can make the inner wall of the installation cavity 14 fit tightly with the refrigerator 2, and the flexible ear seat 112 can be deformed so that the ear seat 112 has a higher fit with the shell 12, thereby minimizing thermal resistance and improving heat dissipation efficiency.

[0041] Alternatively, if Figure 3 As shown, a wire hole 1112 is provided on one side of the bracket body 111, and the wire hole 1112 is communicated with the installation cavity 14. It can be understood that the refrigerator 2 has a wire 21, and the wire 21 passes through the wire hole 1112 to the outside.

[0042] In some embodiments, Figure 4 As shown, a through hole 1123 is provided on the ear seat 112, and the through hole 1123 is arranged adjacent to the bracket body 111, and at least part of the through hole 1123 is arranged along the circumferential extension of the bracket body 111. The refrigerator mounting box 1 of the embodiment of the utility model can facilitate the deformation of the ear seat 112 relative to the bracket body 111 by setting the through hole 1123 to the above-mentioned structure.

[0043] Alternatively, if Figure 1 and Figure 4 As shown, the through hole 1123 includes a first section 11231, a second section 11232 and a third section 11233 connected to each other, the first section 11231 is arranged along the circumferential extension of the support body 111, the second section 11232 and the third section 11233 are arranged at both ends of the first section 11231, and the length direction of the second section 11232 and the length direction of the third section 11233 are both orthogonal to the length direction of the first section 11231. For example, the outer peripheral contour of the support body 111 is generally rectangular, and the first section 11231 is arranged at the connection position of the ear seat 112 and the support body 111. The refrigerator installation box 1 of the embodiment of the utility model can facilitate the deformation of the ear seat 112 relative to the support body 111 by setting the through hole 1123 as the above structure, so that the support body 111 and the refrigerator 2 have a higher fit, and the ear seat 112 and the shell 12 have a higher fit, which further reduces the thermal resistance of the refrigerator 2 and improves the heat dissipation efficiency of the refrigerator 2.

[0044] Alternatively, if Figure 4As shown, the ear seat 112 is provided with a matching hole 1124, and the matching hole 1124 is provided between the second section 11232 and the third section 11233. The refrigerator mounting box 1 also includes a threaded member (not shown), which passes through the matching hole 1124 and is connected to the housing 12. For example, the threaded member is a screw, and the housing 12 is provided with a threaded hole 121, and the screw passes through the matching hole 1124 and is screwed into the threaded hole 121. Since the matching hole 1124 is provided between the second section 11232 and the third section 11233, the ear seat 112 can be easily deformed under the action of the pre-tightening force of the threaded member, so that the ear seat 112 has a high degree of fit with the housing 12.

[0045] Alternatively, if Figure 4 As shown, the ear seat 112 is provided with a positioning hole 1125, and the positioning hole 1125 is provided between the second section 11232 and the third section 11233. Figure 2 As shown, the refrigerator installation box 1 further includes a positioning member 122, which passes through the positioning hole 1125 and is connected to the housing 12. For example, the positioning member 122 is formed on the housing 12. The refrigerator installation box 1 of the embodiment of the utility model can pre-position the fixing bracket 11 by providing the positioning member 122, thereby improving the installation accuracy of the fixing bracket 11.

[0046] In some embodiments, Figure 3 As shown, the fixing bracket 11 is provided with a heat dissipation hole 1111, and the heat dissipation hole 1111 is communicated with the installation cavity 14. The heat dissipation element 13 includes a first heat dissipation block 131 and a second heat dissipation block 132 connected to each other. The first heat dissipation block 131 is arranged in the installation cavity 14, and the second heat dissipation block 132 is arranged in the heat dissipation hole 1111. For example, the first heat dissipation block 131 and the second heat dissipation block 132 are both copper blocks with rectangular cross-sections, and the volume of the first heat dissipation block 131 is greater than the volume of the second heat dissipation block 132. Since the second heat dissipation block 132 is penetrated in the heat dissipation hole 1111, the second heat dissipation block 132 can quickly conduct heat to the outside, thereby further improving the heat dissipation effect of the refrigerator 2.

[0047] Optionally, the fixing bracket 11 and the heat sink 13 may be connected by assembly or integral injection molding.

[0048] Optionally, the shell 12 may be made of a structural member with high thermal conductivity, thereby further improving the heat dissipation efficiency of the refrigerator 2 .

[0049] like Figures 1 to 3 As shown, a refrigerator assembly according to another embodiment of the present invention includes a refrigerator installation box 1 and a refrigerator 2. The refrigerator 2 may be a semiconductor refrigerator 2, and the refrigerator installation box 1 is a refrigerator installation box 1 of the present invention. The refrigerator 2 is arranged in the installation cavity 14, and one side of the refrigerator 2 is in contact with the heat sink 13, and the other side of the refrigerator 2 is in contact with the housing 12.

[0050] According to the refrigerator assembly of the embodiment of the utility model, the refrigerator 2 can be installed in the installation cavity 14, and the heat is dissipated through the heat sink 13. Since the fixing bracket 11 can be squeezed and deformed, when the installation tolerance between the refrigerator 2 and the installation cavity 14 is large, the shape of the fixing bracket 11 can be changed to make the inner wall of the installation cavity 14 fit better with the refrigerator 2, thereby reducing the contact thermal resistance of the refrigerator 2 and improving the heat dissipation effect of the refrigerator 2.

[0051] Alternatively, if Figure 2 As shown, a thermally conductive adhesive layer 15 is provided between the refrigerator 2 and the shell 12 and between the refrigerator 2 and the heat sink 13. The refrigerator assembly of the embodiment of the utility model can fix the refrigerator 2 on the one hand by providing the thermally conductive adhesive layer 15, and on the other hand, can fill the gap between the refrigerator 2 and the shell 12 and the gap between the refrigerator 2 and the heat sink 13, thereby minimizing the thermal resistance and improving the heat dissipation efficiency of the refrigerator 2.

[0052] Optionally, the thickness of the thermally conductive adhesive layer 15 is greater than 0 and less than or equal to 0.3 mm. For example, the thickness of the thermally conductive adhesive layer 15 can be 0.1 mm, 0.2 mm or 0.3 mm. The inventors of the present application have found through experimental research that when the thickness of the thermally conductive adhesive layer 15 adopts the above-mentioned numerical range, the problem of low heat dissipation effect caused by the excessive thickness of the thermally conductive adhesive layer 15 can be avoided, and the contact thermal resistance of the refrigerator 2 is reduced, which is conducive to improving the heat dissipation efficiency of the refrigerator 2.
