[0002] With the development of society, more and more equipment is being used. When the equipment is running, it needs to dissipate heat to prevent the temperature of the equipment from being too high, so as to ensure the normal operation of the equipment. Therefore, a heat dissipation device is needed to dissipate heat for the equipment, and a heat exchange plate is usually used to dissipate heat for the equipment.

[0003] In the prior art, heat exchange plates include stamped structure heat exchange plates, extruded profile heat exchange plates, and microchannel and serpentine tube heat exchange plates. Stamped structure heat exchange plates use stamping + brazing process to realize complex flow channels and excellent thermal management performance, but they cannot meet the pressure requirements and require additional box parts for support. The heat exchange plate only realizes the fluid carrier and heat exchange function, and the structural strength and other performance are relatively weak; the hollow profile structure of the extruded profile heat exchange plate realizes the fluid domain through machining and plugging, and is combined into an integral structure through friction welding, argon arc welding and other processes. Its structural strength is high, and it can realize liquid cooling heat exchange requirements as a structural part, but the overall weight is high, the thermal management performance is poor, there are many leakage points, and the process is cumbersome; microchannel and serpentine tube heat exchange plates are mainly suitable for side wall cooling solutions, with high technical barriers and difficulty in implementation, large investment in equipment and fixtures, and are not suitable for large-scale batch applications, and are rarely used by conventional enterprises.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application aims to provide a sandwich heat dissipation plate, aiming to solve the problem in the prior art that the heat exchange plate cannot adjust the heat dissipation capacity according to the equipment.

In addition, the device can also ensure that the guide columns are not damaged by strengthening the components.

[0033] The utility model provides a sandwich heat dissipation plate. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0034] like Figures 1 to 7As shown, a sandwich heat sink is used to dissipate heat for equipment and can meet the system's requirements for the arrangement of thermal management channels by adjusting the internal structure, including a heat exchange plate 1, a heat conductive component 2, and a reinforcing component 3. The heat exchange plate 1 is square and includes two layers, that is, in this embodiment, the heat exchange plate 1 includes an upper plate 11 and a lower plate 12. Therefore, when the sandwich heat sink is installed on the equipment to dissipate heat for the equipment, usually the upper plate 11 or the lower plate 12 is in contact with the equipment, or when the sandwich heat sink is inserted into the equipment, both the upper plate 11 and the lower plate 12 are in contact with the equipment. In general, the wall thickness of the upper plate 11 and the lower plate 12 is about 1.0 mm. When it is necessary to strengthen the bearing capacity of the sandwich heat sink, the thickness of the upper plate 11 and the lower plate 12 can be increased to about 2.5 mm. When it is necessary to improve the heat exchange performance of the sandwich heat sink, the position in contact with the equipment can be appropriately thinned, or the upper plate 11 The upper and lower plates 11 are both made of aluminum. Since aluminum has a high thermal conductivity, the use of aluminum can further improve the heat exchange performance of the sandwich heat sink. The heat conducting component 2 includes a plurality of guide columns 21, which are fixed in the heat exchange plate 1. Specifically, the guide columns 21 are fixed between the upper plate 11 and the lower plate 12. The width and layout of the flow channel are adjusted by adjusting the arrangement of the guide columns 21 between the upper plate 11 and the lower plate 12. In this embodiment, the guide columns 21 are thin-walled columns with an outer diameter of 10 mm, a height of 10 mm, and a wall thickness of 0.5 mm. A flow channel structure is formed by overlapping every two thin-walled columns in a building block-like manner, so that the coolant flows in the flow channel structure. In other embodiments, the guide column 21 can also be a hexagonal column or a square column, etc., and the flow channel structure is also formed by overlapping the guide column 21 in a building block-like manner, and the outer diameter, height, wall thickness, etc. of the guide column 21 can also be adjusted, so that the heat exchange performance of the sandwich heat sink is more matched with the heat generation of the equipment, and the sandwich heat sink can also more accurately control the temperature of the equipment by absorbing the heat generated by the equipment to maintain the stable operation of the equipment; the reinforcement component 3 is installed on the heat conductive component 2, specifically, the reinforcement component 3 is installed around the heat conductive component 2, and is used to strengthen the structural strength of the sandwich heat sink, and at the same time, the sandwich heat sink is sealed to prevent the guide column 21 in the heat conductive component 2 from being impacted and causing the formed flow channel structure to be destroyed, thereby preventing the coolant from leaking out of the flow channel structure formed by the guide column 21 when the sandwich heat sink is cooling the equipment.

[0035] Furthermore, the heat exchange plate 1 also includes a water inlet joint 13 and a water outlet joint 14. The water inlet joint 13 is installed at one end of the upper plate 11. The water inlet joint 13 is connected to the heat conduction component 2. Cooling liquid is input into the heat conduction component 2 through the water inlet joint 13, so that the heat conduction component 2 can absorb the heat generated by the equipment, thereby dissipating the heat of the equipment; in addition, the front end of the water inlet joint 13 is a round tube, and is stepped, that is, the length of the pipe in the inner circle of the front end of the water inlet joint 13 is longer than the length of the pipe in the outer circle of the front end, which is convenient for the water pipe or other structures for conveying coolant to be inserted into the front end of the water inlet joint 13, so that the water pipe and other structures are fixed on the water inlet joint 13, preventing the water pipe from falling when conveying coolant to the heat exchange plate 1 through the water inlet joint 13, thereby maintaining the continuous delivery of coolant. The water outlet joint 14 is installed at the other end of the upper plate 11 and is located on the same side as the water inlet joint 13. The sandwich heat sink discharges the coolant in the heat-conducting component 2 through the water outlet joint 14, ensuring that the coolant that has absorbed heat is discharged from the heat-conducting component 2 in time, and at the same time, new coolant flows into the heat-conducting component 2 through the water inlet joint 13, so that the sandwich heat sink continues to absorb the heat generated by the equipment, thereby enabling the sandwich heat sink to continuously dissipate heat for the equipment; in addition, the front end of the water outlet joint 14 is a round tube, and is stepped, that is, the pipe length of the inner circle of the front end of the water outlet joint 14 is longer than the pipe length of the outer circle of the front end, so that the drain pipe or other structure for discharging the coolant is conveniently inserted into the front end of the water outlet joint 14, so that the drain pipe and other structures for discharging the coolant are fixed on the drain joint, preventing the drain pipe from falling when discharging the coolant in the heat-conducting component 2 through the drain joint, maintaining the continuous discharge of the coolant that has absorbed the heat, allowing new coolant to continue to flow in, allowing the sandwich heat sink to continuously absorb the heat generated by the equipment, thereby maintaining the continuous and stable operation of the equipment.

[0036] In order to allow the coolant flowing from the water inlet structure to flow into the heat conducting component 2 in time and to allow the coolant to spread throughout all positions in the heat conducting component 2, thereby improving the heat dissipation efficiency of the sandwich heat sink, the heat conducting component 2 also includes a guide inlet 22, such as Figure 3As shown, the guide inlet 22 is formed by overlapping the guide columns 21. Specifically, the guide inlet 22 is arranged between the upper plate 11 and the lower plate 12, near a corner of the sandwich heat sink, and the guide inlet 22 is formed by splicing a plurality of guide columns 21. One end of the guide inlet 22 is closed, and a closed port is formed by overlapping the guide columns 21 to prevent the coolant from flowing out of the closed port, ensuring that the coolant flows into the flow channel structure of the sandwich heat sink; the other end of the guide inlet 22 is formed by overlapping two rows of guide columns 21 to form two parallel boundaries, and between the two boundaries is a flow channel with a certain width, which is connected to the flow channel structure of the sandwich heat sink. In this embodiment, the width of the flow channel is 50mm. At this time, the diversion inlet 22 is connected to the water inlet joint 13, so when the coolant enters from the water inlet joint 13, the coolant flows into the diversion inlet 22, and then flows along the flow channel of the diversion inlet 22, flows to the flow channel structure in the sandwich heat sink, and at the same time absorbs the heat generated by the equipment to dissipate the heat of the equipment.

[0037] In order to gather the coolant that has absorbed heat to one place so as to discharge the coolant that has absorbed heat in a centralized manner and ensure that new coolant can enter the sandwich heat sink in time to absorb the heat generated by the equipment, the heat conduction component 2 also includes a guide outlet 23, and the guide outlet 23 is formed by overlapping the guide columns 21. Specifically, the guide outlet 23 is arranged between the upper plate 11 and the lower plate 12, close to the other corner of the sandwich heat sink, and the guide outlet 23 is formed by splicing a plurality of guide columns 21 in one layer, and the guide inlet 22 and the guide outlet 23 are located on the same side of the sandwich heat sink. At the same time, one end of the guide outlet 23 is closed, and a closed port is formed by overlapping the guide column 21 to prevent the coolant from flowing out of the closed port, ensuring that the coolant can be discharged from the sandwich heat sink through the guide outlet 23; the other end of the guide outlet 23 is formed by overlapping two rows of guide columns 21 into two parallel boundaries, and there is a flow channel of a certain width between the two boundaries. In this embodiment, the width of the flow channel is 50mm, and this flow channel is connected to the flow channel structure in the sandwich heat sink. At this time, the guide outlet 23 is connected to the water outlet joint 14, so when the coolant flowing in various places in the sandwich heat sink absorbs the heat generated by the equipment, it flows into the flow channel of the guide outlet 23, and then these coolants flow to the water outlet joint 14 after flowing through the flow channel of the guide outlet 23, so that the coolant flows out of the sandwich heat sink from the water outlet joint 14.

[0038] Furthermore, in order to allow the coolant to flow between the upper plate 11 and the lower plate 12, and at the same time ensure that the coolant can absorb the heat generated by the equipment when flowing between the upper plate 11 and the lower plate 12, the heat conduction component 2 also includes a guide channel 24, and the guide channel 24 is formed by overlapping the guide columns 21. Specifically, each channel is composed of two rows of guide columns 21 overlapping to form a gap between two parallel boundaries. The width and arrangement of the guide channel 24 are determined according to the heat dissipation requirements of the equipment. For example, when a certain area of ​​the equipment needs to strengthen the heat dissipation, it is necessary to increase the number of guide channels 24 formed in this area by adjusting the position of the guide column 21 between the upper plate 11 and the lower plate 12 corresponding to this area of ​​the equipment, so that the coolant flows in this area multiple times, thereby increasing the absorption rate of the coolant to the heat generated by this area of ​​the equipment, and then controlling the temperature of the equipment to meet specific requirements. When a certain area of ​​the equipment does not need strong heat dissipation, the number of channels in this area can be reduced by adjusting the guide column 21, thereby reducing the absorption rate of the heat generated by the equipment in this area by the coolant, and controlling the temperature of various parts of the equipment to be maintained at a certain value, thereby avoiding large temperature differences between different areas of the equipment that affect the operation of the equipment. Generally speaking, in order to ensure that the sandwich heat sink has a certain absorption capacity for the heat generated by the equipment, three S-shaped heat dissipation channels 241 and a collective drainage channel 242 are formed between the upper plate 11 and the lower plate 12 through the arrangement of a number of guide columns 21, such as Figure 3 As shown, the three heat dissipation channels 241 are designed in parallel, and the coolant in the three heat dissipation channels 241 is collected and then flows into the drainage channel 242. At this time, the guide channel 24 is respectively connected with the guide inlet 22 and the guide outlet 23, that is, the guide inlet 22 is connected with the heat dissipation channel 241, and the guide outlet 23 is connected with the drainage channel 242. Therefore, when the coolant enters the guide inlet 22 through the water inlet joint 13, the coolant first flows in the guide inlet 22, and then the coolant flows from the guide inlet 22 to the three heat dissipation channels arranged in parallel. 241, while the coolant flows in the heat dissipation channel 241, it absorbs the heat generated by the equipment at the corresponding position of the heat dissipation channel 241. After the coolant flows through the heat dissipation channel 241, it is collected and then flows into the drainage channel 242. When the coolant flows in the drainage channel 242, it can also absorb the heat generated by the equipment area at the corresponding position of the drainage channel 242. Then, after the coolant flows through the drainage channel 242, it flows into the guide outlet 23, and then the coolant in the guide outlet 23 is discharged from the sandwich heat sink through the water outlet joint 14.

[0039] After adjusting the position of the guide column 21 between the upper plate 11 and the lower plate 12, the guide column 21 needs to be fixed between the upper plate 11 and the lower plate 12. Since the guide column 21, the upper plate 11 and the lower plate 12 are all made of metal materials such as aluminum, in this embodiment, the guide column 21 is welded between the upper plate 11 and the lower plate 12 by a brazing process, so that the guide column 21, the upper plate 11 and the lower plate 12 form a closed cavity, and the coolant flows in the guide channel 24 in the closed cavity to absorb the heat generated by the equipment. The brazing process includes tunnel brazing, vacuum brazing, etc. In other embodiments, the guide column 21 can also be fixed between the upper plate 11 and the lower plate 12 by other methods. In order to further strengthen the structural strength of the sandwich heat sink and prevent other objects from impacting the sandwich heat sink and causing damage to the sandwich heat sink, for example, when an object impacts the guide column 21, the closed cavity between the guide column 21 and the upper plate 11 and the lower plate 12 may be damaged, thereby causing the guide channel 24 to be damaged, causing the coolant to leak and affecting the heat absorption effect of the sandwich heat sink. Therefore, the structural strength of the sandwich heat sink is strengthened by strengthening the component 3. Specifically, the strengthening component 3 includes a strengthened edge seal 31, which is in the shape of a frame. The strengthened edge seal 31 is installed on the outer ring of the heat conducting component 2, that is, when the guide column 21 is installed, the guide column 21 is protected by the strengthened edge seal 31. When the sandwich heat sink is in use, it is used to resist objects impacting the guide column 21, prevent the guide column 21 from being damaged by the impact of objects, and maintain the stable use of the sandwich heat sink.

[0040] Furthermore, in order to improve the applicability of the sandwich heat sink, it is necessary to further improve the structural strength of the sandwich heat sink, so the reinforcement component 3 also includes a frame bottom plate 32, such as Figure 5 and Figure 6 As shown, the frame bottom plate 32 is installed at the bottom of the sandwich heat sink to strengthen the structural strength of the sandwich heat sink. The frame bottom plate 32 includes a reinforcing cross beam 321 and a reinforcing longitudinal beam 322. The reinforcing cross beam 321 and the reinforcing longitudinal beam 322 are perpendicular to each other. Five reinforcing cross beams 321 are installed between two reinforcing longitudinal beams 322 at intervals. When the frame bottom plate 32 is installed on the sandwich heat sink, the reinforcing longitudinal beam 322 and the reinforcing longitudinal beam 322 are in contact with the lower plate 12, so as to strengthen the structural strength of the sandwich heat sink, for example, to prevent the lower plate 12 from bending and breaking when impacted.

[0041] In addition to strengthening the structural strength of the sandwich heat sink through the frame bottom plate 32, the reinforcement component 3 also includes a plurality of module mounting beams 33, such as Figure 5 and Figure 6As shown, the reinforcement component 3 can also strengthen the structural strength of the sandwich heat sink through the module mounting beam 33. Specifically, the module mounting beam 33 is installed at the upper end of the heat exchange plate 1, that is, the module mounting beam 33 is installed on the side of the upper plate 11 away from the guide column 21. In this embodiment, the reinforcement component 3 includes three module mounting beams 33, which are in the shape of long strips, and the length is equal to the length of the short side of the upper plate 11. The module mounting beams 33 are respectively installed at both ends and the middle of the upper plate 11. The three module mounting beams 33 are parallel to each other, so that when the module mounting beam 33 is installed on the upper plate 11, the upper plate 11 is prevented from being completely broken. At the same time, the module mounting beam 33 can also assist in performing other operations on the sandwich heat sink. For example, when the sandwich heat sink needs to be hoisted, the hoisting device clamps the sandwich heat sink by clamping the module mounting beam 33, and then moves the sandwich heat sink to a specific position. Similarly, rollers or slide rails can be installed under the frame bottom plate 32 to facilitate movement of the sandwich heat sink, thereby expanding the scope of use of the sandwich heat sink.

[0042] In order to expand the use scope of the sandwich heat sink, and facilitate the assembly of spare parts or the insertion of wiring harnesses on the sandwich heat sink, the sandwich heat sink also includes a mounting seat 4, which is arranged next to the reinforcing component 3, and the spare parts can be installed on the mounting seat 4, and the wiring harness can also be inserted into the mounting seat 4. Specifically, the mounting seat 4 is square and arranged at one end of the sandwich heat sink, and in order to provide an installation space for the mounting seat 4, one end of the heat-conducting component 2 is recessed inward, and the mounting seat 4 is arranged in this recess, so the flow guide inlet 22, the flow guide channel 24 and the flow guide outlet 23 of the heat-conducting component 2 surround the outer periphery of the mounting seat 4; and when there is no need to assemble spare parts or insert wiring harnesses on the sandwich heat sink, the sandwich heat sink can cancel the mounting seat 4, and at this time, the heat-conducting component 2 no longer needs to reserve an installation position for the mounting seat 4, so the flow guide channel 24 is arranged in a larger area in the sandwich heat sink, thereby improving the ability of the sandwich heat sink to absorb the heat generated by the equipment.

[0043] To sum up, when it is necessary to assemble the sandwich heat sink in the present application and use the sandwich heat sink to absorb the heat generated by the equipment, first arrange the guide column 21 on the lower plate 12, so as to form a guide inlet 22, a guide channel 24 and a guide outlet 23 on the lower plate 12 through the arrangement of the guide column 21, and then fix the guide column 21 on the lower plate 12. In this embodiment, the guide column 21 is welded to the lower plate 12 by a brazing process, and then the upper plate 11 is fixed to the guide column 21. In this embodiment, the upper plate 11 is also welded to the guide column 21 by a brazing process, and then the reinforced edge sealing 31 is installed around the heat conducting component 2 to strengthen the strength of the sandwich heat sink. At the same time, the module mounting beam 33 can be installed on the upper plate 11, the frame bottom plate 32 can be installed on the lower plate 12, and the mounting seat 4 can be set at the front end of the heat conducting component 2 as needed.

[0044] When the sandwich heat sink is assembled, it is installed on the equipment that needs heat dissipation, and then the water inlet joint 13 is connected to the infusion pipe, and the water outlet joint 14 is connected to the drainage pipe, so that the coolant flows from the infusion pipe to the water inlet joint 13, and then flows from the water inlet joint 13 into the diversion inlet 22 and the diversion channel 24, absorbs the heat generated by the equipment while flowing in the diversion channel 24, and maintains the temperature of the equipment stable. The coolant that has absorbed the heat flows from the diversion channel 24 to the diversion outlet 23, and then flows from the diversion outlet 23 to the water outlet joint 14, and is discharged from the sandwich heat sink from the water outlet joint 14 and flows to the drainage pipe. Therefore, the coolant continues to flow in the sandwich heat sink, and then continues to absorb the heat generated by the equipment.

[0045] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
