Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, and in particular to a refrigeration module device. Background Art

[0002] The refrigerator uses a semiconductor refrigeration module for refrigeration, wherein the semiconductor refrigeration module is formed by combining a semiconductor refrigeration sheet and related parts. Since the overall size of the semiconductor refrigeration sheet is small, especially the thickness, when it is necessary to dissipate heat and cold at the same time, it is necessary to install a heat sink and a cooling block, and it is also necessary to isolate the hot end and the cold end, that is, to install a heat insulation block. However, since these parts are independent of each other, it is impossible to position each part well during the organization process, and it is difficult to assemble.

[0003] The cooling plates, heat sinks and cooling blocks in the semiconductor refrigeration module need to be fixed with thermal conductive adhesive. After applying the thermal conductive adhesive, the suction force between the parts increases. If the parts cannot be positioned at once, the parts will be installed in the wrong position, making it difficult to install the parts. The semiconductor refrigeration plates may also be damaged during the reinstallation process. Summary of the invention

[0004] The present application provides a refrigeration module device to solve the problem of difficulty in assembling a refrigeration module.

[0005] The present application provides a refrigeration module device, comprising: a refrigeration module and a tooling body; the tooling body comprises a base plate and an outer shell, a boss is arranged in the middle of the base plate, the boss is a square structure, and grooves are symmetrically arranged at both ends of the boss; the outer shell is a hollow square structure, and one end of the outer shell is fixedly connected to the base plate.

[0006] The refrigeration module includes a cooling block, a first insulation block, a second insulation block, a third insulation block, a cooling fin, a heat sink, a nut and a bolt; the first insulation block is arranged in the groove, and the first insulation block is fixedly connected to the nut; the cooling block is arranged in the outer shell through the nut, the second insulation block is connected to the cooling block through the nut, the cooling fin is connected to the second insulation block, the heat sink is connected to the second insulation block through the nut, and the bolt passes through the third insulation block and is detachably connected to the nut.

[0007] By arranging the first thermal insulation block and the nut in the groove, the cooling block, the second thermal insulation block, the refrigeration plate, the heat sink, the third thermal insulation block and the bolt are connected in sequence. Since the positions of the first thermal insulation block and the nut are fixed, when installing the various components of the refrigeration module, it is only necessary to place the various components of the refrigeration module in the tooling body in sequence, thereby simplifying the installation process and improving the installation efficiency.

[0008] Optionally, the groove is a square structure that is recessed inwards, the first heat insulating block is a square structure, and the first heat insulating block is inserted into the groove; the groove is provided with a connecting hole, and the diameter of the connecting hole is larger than the diameter of the bolt. The position of the first heat insulating block is fixed by the groove, and by setting the diameter of the connecting hole larger than the diameter of the bolt, the bolt and the nut are more firmly connected during installation.

[0009] Optionally, a square structure protruding outward is provided in the middle of the cooling block, a square groove is provided in the middle of the second heat insulation block, and the square structure of the cooling block passes through the square groove of the second heat insulation block to be connected to the second heat insulation block. By arranging the square structure to be connected to the second heat insulation block, the refrigeration sheet is connected to the square structure, which can better fix the square structure on the one hand, facilitate setting the refrigeration sheet in the correct position during installation, and protect the refrigeration sheet on the other hand.

[0010] Optionally, the first heat insulating block and the nut are integrally formed, the first heat insulating block and the nut are provided with internal threads, and the first heat insulating block and the nut are detachably connected to the bolt through the internal threads. By providing the detachable connection between the bolt and the nut, installation and disassembly are facilitated. The integrally formed structure of the nut and the first heat insulating block has a large overall strength, thereby improving the overall connection strength of the refrigeration module.

[0011] Optionally, limit blocks and arc-shaped openings are provided on both sides of the shell, the distance from the end of the limit block away from the bottom plate to the bottom plate is a first distance, the distance from the end of the arc-shaped opening close to the bottom plate to the bottom plate is a second distance, and the first distance is greater than the second distance.

[0012] By providing the limit block, the cooling block is prevented from contacting the bottom plate, thereby reducing the occurrence of the cooling block being squeezed and damaged. By providing the arc-shaped opening, it is convenient to take out the cooling module after the installation is completed.

[0013] Optionally, screw holes are symmetrically arranged at both ends of the bottom plate, and the bottom plate is fixed to the mounting surface through the screw holes. By symmetrically arranging the screw holes at both ends of the bottom plate, the bottom plate is fixed to the mounting surface of the operating table.

By setting the inner width of the shell to be greater than the width of the refrigeration module, and the inner length of the shell to be greater than the length of the refrigeration module, the refrigeration module can be placed in the shell during installation. At the same time, the shell also plays a role of limiting, preventing the refrigeration module from shaking or shifting during installation, and reducing the occurrence of incorrect installation positions.

[0015] Optionally, the housing and the bottom plate are integrally formed. The integrally formed structure has high overall strength, which reduces the occurrence of unstable connection between the housing and the bottom plate caused by external forces.

[0025] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0026] The semiconductor refrigeration module is composed of a semiconductor refrigeration sheet and related parts, wherein the heat sink, the cooling sheet and the cooling block need to be insulated by a heat insulation block. In some embodiments, when installing the cooling sheet, the heat sink, the cooling sheet and the cooling block in the semiconductor refrigeration module, thermal conductive glue needs to be applied for bonding. During the bonding process, the connection position between the two parts may be wrong, which will lead to the problem of difficulty in installing other parts.

[0027] In order to solve the problem of low installation efficiency and difficulty in installing a refrigeration module, the present application provides a refrigeration module device. Figure 1-Figure 5 , Figure 1 This is a schematic diagram of the installation of the refrigeration module. Figure 2 This is a schematic diagram of the main structure of the tooling. Figure 3 This is a perspective view of the refrigeration module device. Figure 4 It is a schematic diagram of the structure of the refrigeration module device. Figure 5The refrigeration module device provided in the present application comprises a refrigeration module and a tooling body; the tooling body comprises a bottom plate 1 and a shell 2, a boss 201 is arranged in the middle of the bottom plate 1, the boss 201 is a square structure, and grooves 202 are symmetrically arranged at both ends of the boss 201; the shell 2 is a hollow square structure, and one end of the shell 2 is fixedly connected to the bottom plate 1.

[0028] The refrigeration module includes a cooling block 4, a first thermal insulation block 3, a second thermal insulation block 5, a third thermal insulation block 8, a cooling fin 6, a heat sink 7, a nut 9 and a bolt 10; the first thermal insulation block 3 is arranged in the groove 202, and the first thermal insulation block 3 is fixedly connected to the nut 9; the cooling block 4 is arranged in the outer shell 2 through the nut 9, the second thermal insulation block 5 is connected to the cooling block 4 through the nut 9, the cooling fin 6 is connected to the second thermal insulation block 5, the heat sink 7 is connected to the second thermal insulation block 5 through the nut 9, and the bolt 10 passes through the third thermal insulation block 8 and is detachably connected to the nut 9.

[0029] During installation, firstly, the first thermal insulation block 3 is set in the groove 202, and the first thermal insulation block 3 is fixedly connected with the nut 9. For example, the first thermal insulation block 3 is first connected with the nut 9 by welding, and then the first thermal insulation block 3 and the nut 9 are placed in the groove 202. The first thermal insulation block 3 and the nut 9 play a role of limiting. When the cooling block 4, the second thermal insulation block 5 and the heat sink 7 are installed in sequence, the nut 9 passes through the cooling block 4, the second thermal insulation block 5 and the heat sink 7. Since the first thermal insulation block 3 is plugged into the groove 202, the first thermal insulation block 3 cannot be moved during the installation process, so that the positions of the cooling block 4, the second thermal insulation block 5 and the heat sink 7 are more accurate during the subsequent installation process, thereby improving the installation efficiency and reducing the occurrence of installation difficulties caused by incorrect installation positions during installation.

[0030] It is understandable that the grooves 202 are symmetrically arranged on both sides of the boss 201, and the number of the grooves 202 can be multiple. In order to reduce the difficulty of installation, in this embodiment, the number of the grooves 202 is two. A groove 202 is arranged on each side of the boss 201. During the installation process, a first heat insulation block 3 and a nut 9 are arranged in each of the two grooves 202, which can play a positioning role. At the same time, the fewer the number of grooves 202, the fewer the number of screw holes opened in the cooling block 4, the second heat insulation block 5 and the heat sink 7, which reduces the difficulty of installation.

[0031] After the cooling block 4 is installed, the second insulation block 5, the refrigeration fins 6 and the heat sink 7 are connected to the cooling block 4 in sequence. The second insulation block 5, the refrigeration fins 6 and the heat sink 7 are arranged in the shell 2 through nuts 9. Due to the limiting effect of the nuts 9, the second insulation block 5, the refrigeration fins 6 and the heat sink 7 are less likely to have the wrong installation position during the installation process.

[0032] Finally, the first heat insulation block 3, the cooling block 4, the second heat insulation block 5, the cooling sheet 6, the heat sink 7 and the third heat insulation block 8 are connected together by bolts 10 and nuts 9 to form a refrigeration module. The bolts 10 and nuts 9 are detachably connected, which is convenient for installation and disassembly, maintenance and repair.

[0033] In some embodiments, the first thermal insulation block 3 and the nut 9 are integrally formed, the first thermal insulation block 3 and the nut 9 are provided with internal threads, and the first thermal insulation block 3 and the nut 9 are detachably connected to the bolt 10 through the internal threads. Among them, the first thermal insulation block 3 and the nut 9 are integrally formed, and the integrally formed structure makes the connection between the first thermal insulation block 3 and the nut 9 more secure.

[0034] The first heat insulating block and the nut 9 are provided with internal threads. During installation, the bolt 10 first passes through the third heat insulating block 8, and then passes through the heat sink 7, the second heat insulating block 5 and the cooling block 4 in sequence, and is connected with the nut 9. Since the first heat insulating block 3 is set in the groove 202 and is limited, the nut 9 is also limited in the fixed connection with the first heat insulating block 3. The bolt 10 is turned to make the bolt 10 pass through the nut 9 and the first heat insulating block 3, and finally the first heat insulating block 3, the cooling block 4, the second heat insulating block 5, the cooling fin 6, the heat sink 7 and the third heat insulating block 8 are fixed together to form a refrigeration module.

[0035] In some embodiments, the groove 202 is a square structure that is recessed inward, the first heat insulation block 3 is a square structure, and the first heat insulation block 3 is inserted into the groove 202; the groove 202 is provided with a connecting hole, and the diameter of the connecting hole is larger than the diameter of the bolt 10. Figure 3 As shown, after the bolt 10 is completely screwed into the nut 9, it will extend a certain distance from the first heat insulating block 3. Providing the connecting hole can increase the screwing depth of the bolt 10, making the connection between the bolt 10 and the nut 9 more secure.

[0036] In some embodiments, a square structure protruding outward is provided in the middle of the cooling block 4, a square groove is provided in the middle of the second heat insulation block 5, and the square structure of the cooling block 4 passes through the square groove of the second heat insulation block 5 and is connected to the second heat insulation block 5. The cooling fin 6 is divided into a heat absorption surface and a heat dissipation surface. The square structure of the cooling block is connected to the heat absorption surface of the cooling fin 6, and the area of ​​the connection surface between the square structure of the cooling block and the cooling fin 6 is consistent with the area of ​​the cooling fin 6. The heat sink is connected to the heat dissipation surface of the cooling fin 6. The heat insulation block is required to isolate the heat sink from the cooling block. By setting the second heat insulation block 5 between the cooling block and the heat sink, the heat transfer between the cooling block and the heat sink is reduced.

[0037] Among them, a directional groove is provided in the middle of the second heat insulation block 5. During installation, after aligning the directional groove of the second heat insulation block 5 with the square structure of the cooling block, press the second heat insulation block 5 to connect the second heat insulation block 5 with the cooling block, and then apply thermal conductive glue on the upper surface of the square structure of the cooling block, and then connect it to the heat sink. By providing a groove in the middle of the second heat insulation block 5 and a square structure of the cooling block, the connection relationship between the second heat insulation block 5 and the cooling block is more stable and easy to install.

[0038] It can be understood that in order to reduce the possibility of damage to the refrigeration sheet 6 due to squeezing of the refrigeration sheet 6, the cooling block 4 and the heat sink 7 during installation, the thickness of the second thermal insulation block 5 is the sum of the thickness of the cube structure of the cooling block 4 and the thickness of the refrigeration sheet 6. After the refrigeration sheet 6 is connected to the cooling block 4, the side of the refrigeration sheet 6 away from the cooling block 4 and the side of the second thermal insulation block 5 away from the cooling block 4 are on the same horizontal plane, which can ensure that the refrigeration sheet 6 is in full contact with the heat sink 7 and protect the refrigeration sheet 6 through the second thermal insulation block 5.

[0039] In some embodiments, Figure 2 As shown, both sides of the shell 2 are provided with stop blocks 203 and arc-shaped openings 204, the distance between the end of the stop block 203 away from the bottom plate 1 and the bottom plate 1 is a first distance, and the distance between the end of the arc-shaped opening 204 close to the bottom plate 1 and the bottom plate 1 is a second distance, and the first distance is greater than the second distance. Both sides of the shell 2 are provided with arc-shaped openings 204, and both sides of the inner wall of the shell 2 provided with the arc-shaped openings 204 are provided with stop blocks 203, and the stop blocks 203 are step-shaped structures protruding toward the inner side of the shell 2. During installation, when the cooling block 4 is set in the shell 2, both sides of the cooling block 4 abut against the stop blocks 203, so that the cooling block 4 is suspended, and one side of the cooling block 4 does not contact the bottom plate 1, so as to prevent the cooling block 4 from being damaged due to the abutment between the cooling block 4 and the bottom plate 1 when the cooling block 4 is pressed downward.

[0040] The arc opening 204 is a notch opened on both sides of the housing 2, and the bottom of the notch is an arc-shaped structure. The distance between the bottom of the arc opening 204 and the bottom plate 1 is smaller than the distance between the upper surface of the stop block 203 and the bottom plate 1, so that the refrigeration module can be taken out through the arc opening 204 after installation. For example, after the refrigeration module is installed, a tool is inserted into the arc opening 204. Since the arc opening 204 is recessed to a large depth, the tool can be engaged with the edge of the refrigeration module, and then the tool can be pulled away from the bottom plate 1 to take the refrigeration module out of the housing 2. By providing the arc opening 204 on both sides of the housing 2, it is convenient to take out the refrigeration module after the refrigeration module is assembled.

[0041] In some embodiments, screw holes 101 are symmetrically provided at both ends of the bottom plate 1, and the bottom plate 1 is fixed to the mounting surface through the screw holes 101. When installing the refrigeration module, in order to avoid the refrigeration module installation error caused by the movement of the tooling body, such as Figure 4 As shown, screw holes 101 can be symmetrically arranged at both ends of the base plate 1, and the tooling body can be fixed to the mounting surface of the operating table through the screw holes 101. For example, four screw holes 101 are symmetrically arranged at both ends of the base plate 1, and screws are used to pass through the screw holes 101 to fix the tooling body to the mounting surface of the operating table. It can be understood that the number of screw holes 101 can be two or more, as long as the tooling body can be fixed on the operating table. For example, in this embodiment, the number of screw holes 101 is four, with two screw holes 101 at each end of the base plate 1. The tooling body is fixed through the screw holes 101 to provide a stable installation environment.

[0042] In some embodiments, the inner width of the housing 2 is greater than the width of the refrigeration module, and the inner length of the housing 2 is greater than the length of the refrigeration module. When assembling the various components of the refrigeration module, they all need to be arranged in the housing 2 in sequence. The inner width of the housing 2 is set to be greater than the width of the refrigeration module, and the inner length of the housing 2 is set to be greater than the length of the refrigeration module, so that the refrigeration module can be arranged in the housing 2. It can be understood that the housing 2 also plays a role in limiting, such as Figure 3 As shown, the inner length of the housing 2 is slightly larger than the length of the refrigeration module. By setting the inner length of the housing 2 to be slightly larger than the length of the refrigeration module, the various components of the refrigeration module can be fixed without displacement during installation, simplifying the installation process and reducing the occurrence of incorrect installation positions due to component movement during installation.

[0043] In some embodiments, the housing 2 is integrally formed with the bottom plate 1. By providing the housing 2 and the bottom plate 1 as an integrally formed structure, the overall strength of the tooling body is improved, and the problem of problems in installing the refrigeration module caused by deformation of the tooling body when the refrigeration module is installed inside the tooling body is reduced.

[0044] In another embodiment, the tooling body is composed of multiple parts, and the power is provided by a cylinder to push the multiple parts of the tooling body apart or merge them into one, and a cylinder is provided on the bottom plate 1. During installation, the tooling body is first merged together by the cylinder, and then the first insulation block 3, the cooling block 4, the second insulation block 5, the cooling sheet 6, the cooling sheet 7, and the third insulation block 8 are assembled together in sequence, and then the cylinder can be controlled to push the tooling body apart, and then the refrigeration module can be taken out, or after the refrigeration module is assembled and fixed, the refrigeration module can be pushed out by the cylinder of the bottom plate 1. By setting the tooling body to be controlled by the cylinder, it is convenient to take out the refrigeration module after the refrigeration module is assembled.

[0045] It can be seen from the above technical scheme that the present application provides a refrigeration module device, including: a refrigeration module and a tooling body; the tooling body includes a base plate 1 and a shell 2, a boss 201 is arranged in the middle of the base plate 1, the boss 201 is a square structure, and grooves 202 are symmetrically arranged at both ends of the boss 201; the shell 2 is a hollow square structure, and one end of the shell 2 is fixedly connected to the base plate 1; the refrigeration module includes a cooling block 4, a first insulation block 3, a second insulation block 5, a third insulation block 8, a cooling plate 6, a heat sink 7, a nut 9 and a bolt 10; the first insulation block 3 is arranged in the groove 202, and the first insulation block 3 is fixedly connected to the nut 9; the cooling block 4 is arranged in the shell 2 through the nut 9, the second insulation block 5 is connected to the cooling block 4 through the nut 9, the cooling plate 6 is connected to the second insulation block 5, the heat sink 7 is connected to the second insulation block 5 through the nut 9, and the bolt 10 passes through the third insulation block 8 and is detachably connected to the nut 9. By setting the first insulation block and the nut 9 in the groove 202 for positioning, the cooling block 4, the second insulation block 5, the cooling plate 6, the heat sink 7 and the third insulation block 8 are installed in sequence, simplifying the installation process to solve the problem of difficult assembly of the refrigeration module.
