Description

Technical Field

[0001] This utility model relates to the field of heat sinks, specifically to a radiator module and a liquid-cooled heat sink. Background Technology

[0002] With the continuous increase in power density of semiconductor chips, power devices, and power batteries, traditional air cooling methods are no longer sufficient to meet temperature rise control requirements. Liquid cooling, with its advantages of high specific heat capacity and high heat transfer coefficient, has become the mainstream solution for high-performance heat dissipation scenarios. The radiator is one of the main components of a liquid cooling radiator. The working mechanism of the radiator is that the relatively high-temperature coolant is cooled by external heat dissipation devices such as fans as it flows through the radiator. After cooling, the relatively low-temperature coolant flows out and is circulated for use by external equipment.

[0003] In existing radiator structures, for ease of processing, the radiator's inlet and outlet are usually integrated into the same main chamber structure. The main chamber structure is divided into an inlet chamber and an outlet chamber. The relatively high-temperature coolant enters the inlet chamber from the inlet, flows through the forward heat pipes, reaches the secondary chamber structure on the other side, and then flows back to the outlet chamber of the main chamber structure through the reverse heat pipes and is discharged through the outlet. The cooling fan simultaneously blows air onto both the forward and reverse heat pipes to dissipate heat. With this implementation, since only the main chamber structure needs to be processed, processing costs can be saved.

[0004] In actual processing, with the cooling fan unchanged, the coolant flow rate constant, and the number of heat pipes the same, on the one hand, because the temperature difference between the coolant in the reverse heat pipe and the room temperature is low, the heat dissipation efficiency of the reverse heat pipe for the coolant is poor; on the other hand, because the water circuit is extended in effect, the pressure requirement for the circulation pump is greater, which limits the selection range of the circulation pump.

[0005] To fully utilize the cooling efficiency of the cooling fan, the structure of the radiator module needs to be improved, while also taking into account cost-effectiveness. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Accordingly, this utility model provides a radiator module 503, including an inlet cylinder 6, an outlet cylinder 2, a first connecting plate 1, a second connecting plate 4, a heat dissipation pipe 12, and heat dissipation fins 13. The inlet tube 6 is provided with an inlet hole 5 and a first mating hole 21, and the two ends of the inlet tube 6 are open to form a first inlet opening and a second inlet opening; the outlet tube 2 is provided with an outlet hole 3 and a second mating hole 23, and the two ends of the outlet tube 2 are open to form a first outlet opening and a second outlet opening. The first end of the heat dissipation pipe 12 is inserted into the first mating hole 21, and the second end of the heat dissipation pipe 12 is inserted into the second mating hole 23; The first connecting plate 1 covers the first inlet opening and the first outlet opening at both ends, and the second connecting plate 4 covers the second inlet opening and the second outlet opening at both ends, and the relative position between the inlet cylinder 6 and the outlet cylinder 2 is fixed based on the first connecting plate 1 and the second connecting plate 4; An inlet cavity 22 is formed between the inlet cylinder 6, the first connecting plate 1, and the second connecting plate 4, and an outlet cavity 24 is formed between the inlet cylinder 6, the first connecting plate 1, and the second connecting plate 4. The inlet cavity 22 and the outlet cavity 24 are connected by the heat dissipation pipe 12. The heat dissipation fins 13 are attached to the heat dissipation pipe 12.

[0032] In actual assembly, the two ends of the heat dissipation pipe 12 are first inserted into the first mating hole 21 and the second mating hole 23 respectively. After insertion and mating, sealing can be achieved by brazing, applying glue, adding sealing rings, etc. When reliability allows, sealing can also be achieved by the form and position fit between the two. Then, heat dissipation fins 13 are laid in the gap of the heat dissipation pipe 12, and heat conduction between the heat dissipation pipe 12 and the heat dissipation fins 13 is achieved by vacuum brazing or other methods. After the heat dissipation pipe 12 and the inlet cylinder 6 are assembled, the first connecting plate 1 and the second connecting plate 4 are installed to seal the first cylinder and the second cylinder respectively.

[0033] Regarding the fixing method of the first connecting plate 1 and the second connecting plate 4, in actual implementation, the first connecting piece and the second connecting piece can be fixed on the first cylinder and the second cylinder. If maintenance is not considered, they can be fixed by brazing directly. In this case, the first connecting plate 1 and the second connecting plate 4 can be conventional planar structures.

[0034] If maintainability is required, the first and second connectors can be fixed to each other by external connectors, thereby indirectly clamping the first and second cylinders between the first connecting plate 1. Accordingly, in this implementation structure, the first and second connectors are mainly responsible for the sealing function of the cylinders.

[0035] In actual implementation, please refer to the attached diagram. Figure 5 The schematic structure, taking the second connecting plate 4 as an example, shows that the second connecting plate 4 has a first sealing protrusion 55 at the position of sealing the first cylinder and a second sealing protrusion 51 at the position of sealing the second cylinder. The outer contour of the first sealing protrusion 55 matches the inner contour of the first cylinder, and the outer contour of the second sealing protrusion 51 matches the inner contour of the second cylinder. In actual processing, when assembling the second connecting plate 4, sealant is applied around the first sealing protrusion 55 and the second sealing protrusion 51 to ensure sealing. The connection stability between the second connecting plate 4 and the cylinder is provided by the structure of the external fixed connecting plate.

[0036] Specifically, the following provides a further structural description of each component.

[0037] Inlet tube 6 Generally, for economic reasons, the inlet cylinder 6 is made of extruded profile with a hollow internal structure and open at both ends to form a first inlet opening and a second inlet opening. In subsequent processing, an input hole 5 and a first mating hole 21 are respectively opened on the side wall of the inlet cylinder 6, with the axis of the input hole 5 perpendicular to the axis of the first mating hole 21. A pipe connector can be installed on the input hole 5, and the outer side of the first mating hole 21 is rounded to facilitate the insertion of the heat dissipation pipe 12. Export tube 2 In fact, the basic structures of the outlet cylinder 2 and the inlet cylinder 6 are the same. In actual processing, the outlet cylinder 2 is made of the same extruded profile as the inlet cylinder 6. In subsequent processing, an outlet hole 3 and a row of second mating holes 23 are opened on the side wall of the outlet cylinder 2. In this subsequent processing, it should be noted that, with reference to the attached drawings... Figure 6In this embodiment of the invention, the heat dissipation pipe 12 is arranged at an angle, which means that the height of the first mating hole 21 on the inlet cylinder 6 and the processing height of the second mating hole 23 on the outlet cylinder 2 are different. In actual implementation, based on the consideration of processing convenience, the mating holes of the heat dissipation pipe 12 at the same height (need to be deviated from the plane of symmetry) can be continuously processed on the extruded profile. After cutting the material from the extruded profile, with the position of the mating hole of the heat dissipation pipe 12 as the reference object, the input hole 5 and the output hole 3 are actually on two opposite planes. Therefore, by processing the corresponding input hole 5 or output hole 3 on different planes, the inlet cylinder 6 or the outlet cylinder 2 can be obtained, which can save processing costs.

[0038] In practical applications, heat pipe 12 and heat dissipation fins 13 are finished parts, while the first connecting plate 1 and the second connecting plate 4 can be processed by machining or CNC machining.

[0039] Specifically, based on the structure described above, in actual operation of the radiator of this utility model embodiment, the coolant is input from the inlet hole 5 into the inlet cavity 22, flows through the heat dissipation pipe 12 to the outlet cavity 24, and is discharged through the outlet hole 3. When the coolant flows through the heat dissipation pipe 12, it transfers heat to the heat dissipation fins 13 for the cooling fan to blow and dissipate heat. In this process, compared with the traditional loop water circuit, the temperature difference between the coolant and the air in all the heat dissipation pipes 12 is larger, and the heat transfer is faster, which is beneficial to improving the heat dissipation efficiency of the radiator module 503. In addition, due to the increase in the total cross-sectional area of ​​the heat dissipation pipe 12, the distance of the heat dissipation flow channel is reduced, which allows for a wider range of selection of circulation pumps and has better economic applicability.

[0040] Furthermore, in order to accommodate the installation of an external radiator fan 11, a first connecting piece 15 extends from the side edge of the first connecting plate 1 toward the heat pipe 12, and a second connecting piece 14 extends from the side edge of the connecting plate toward the heat pipe 12; the first connecting piece 15 and the second connecting piece 14 are configured to cooperate with each other for fixing the external radiator fan 11.

[0041] Furthermore, the radiator module 503 of this utility model embodiment also includes a radiator fan 11, which is fixed on the first connecting piece 15 and the second connecting piece 14.

[0042] Furthermore, considering the integration of the radiator module 503, the radiator fan 11 can also be built into the radiator. Specifically, the radiator module 503 also includes a heat dissipation unit, which includes a support plate, a heat dissipation motor, and heat dissipation blades; The bracket plate is provided with a motor slot, the body of the heat dissipation motor is fixed in the motor slot, and the heat dissipation blades are installed on the output shaft of the heat dissipation motor. The support plate is fixed to one side of the heat dissipation fins 13 via the first connecting plate 1 and / or the second connecting plate 4. When the heat dissipation motor starts, it drives the heat dissipation blades to rotate via the output shaft. The air blowing or suction direction of the heat dissipation blades during rotation is directly opposite to the heat dissipation fins 13. Optionally, the support plate has an X-shaped or Y-shaped structure.

[0043] Both of the above are feasible fan installation methods, and the appropriate method can be selected based on specific needs during implementation.

[0044] In addition to the fan installed in the radiator module 503, the radiator module 503 also includes a fan protection cover 10. The fan protection cover 10 has a U-shaped cross-section and includes a first side plate 7, a fan protection panel 8, and a second side plate 9 connected in sequence. The first side plate 7 is fixed on the first connecting plate 1, and the second side plate 9 is fixed on the second connecting plate 4. The fan protection panel 8 forms a fan mounting area between the heat pipe 12 and the heat dissipation fins 13.

[0045] As described above, the first connecting plate 1 and the second connecting plate 4 can be fixed in position to each other via external connecting lines. Therefore, in actual implementation, the first connecting plate 1 and the second connecting plate 4 can be fixed using the fan protective cover 10. Specifically, the fan protective cover 10 clamps and fixes the first connecting plate 1 and the second connecting plate 4, and the first connecting plate 1 (second connecting plate 4) is mutually limited by the sealing protrusion and the inlet cylinder 6 (outlet cylinder 2), respectively. A stable overall structure is formed between the connecting plate, the inlet cylinder 6, the outlet cylinder 2, and the fan protective cover 10.

[0046] When this implementation method is adopted, the radiator module 503 has good disassembly performance, which is different from the traditional cavity sealing method using vacuum brazing, and can effectively improve the maintainability of the radiator module 503.

[0047] In addition, this embodiment of the invention provides additional implementation structures for the internal water channel structure of the radiator.

[0048] Specifically, the axis of the input hole 5 is perpendicular to the axis of the first mating hole 21, and / or the axis of the output hole 3 is perpendicular to the axis of the second mating hole 23.

[0049] Figure 6 This is a first perspective view of the side structure of the radiator module 503 according to an embodiment of the present utility model. The radiator module 503 in the first perspective view is a structure without the guide plate 30. Figure 7 This is a second perspective view of the side structure of the radiator module 503 according to an embodiment of the present utility model. The radiator module 503 in the second perspective view has a structure with guide plates 30.

[0050] Figure 8 This is a three-dimensional structural diagram of the guide plate 30 according to an embodiment of the present invention. Figure 9 This is a side view of the guide plate 30 according to an embodiment of the present invention. (See attached drawing.) Figure 9 Since the outline of the tiny arc surface is difficult to represent in a three-dimensional schematic diagram, the guide arc surface 32 in the control area 31 is enlarged and adjusted in the attached figure for easier understanding, so that it can be observed in the schematic diagram.

[0051] Furthermore, when the axis of the input hole 5 and the axis of the first mating hole 21 are perpendicular to each other, the cold air radiator module 503 also includes a guide plate 30, which is inserted into the inlet cylinder 6 along the axial direction of the inlet cylinder 6. The guide plate 30 is provided with an adjustment area 31 along the axial direction, which corresponds to the number of the first mating holes 21. Each adjustment area 31 is directly opposite to the corresponding first mating hole 21. The guide plate 30 is provided with a corresponding guide arc surface 32 on each control zone 31; The coolant flowing from the input hole 5 into the inlet cavity 22 is guided by the guide arc surface 32 of the guide plate 30 and then flows to the corresponding first mating hole 21.

[0052] Specifically, since there is only one inlet hole 5, the inlet flow rate and inlet pressure of the high-velocity coolant will vary on different heat dissipation pipes 12 when it flows into the inlet cavity 22 through the inlet hole 5 and then into the heat dissipation pipe 12. In order to regulate the flow rate and pressure at the inlet of the heat dissipation pipe 12, and to reduce the adhesion resistance and frictional resistance when the coolant impacts the inlet cylinder 6, this embodiment of the present invention adds a guide plate 30 structure. Specifically, based on the foregoing description, the inlet cylinder 6 is formed by extrusion of profiles, and its inner wall is difficult to machine into a curved surface structure that meets the requirements. Therefore, this embodiment of the present invention needs to use an additional mechanism to achieve the required function.

[0053] Specifically, the guide plate 30 has an adjustment area 31 along its axial length corresponding to the heat sink 12. The structural shape of the guide arc surface 32 of each adjustment area 31 has slight differences. The purpose of setting it is, on the one hand, to guide the coolant, and on the other hand, to allocate appropriate coolant inlet pressure and coolant inlet flow to each heat sink 12.

[0054] In addition, please refer to the attached figure. Figure 6 and Figure 7The heat dissipation pipe 12 structure shown in this embodiment of the invention is inclined relative to the reference plane established between the inlet cylinder 6 and the outlet cylinder 2. This arrangement helps to reduce the pressure loss of the coolant when the flow direction changes and increases the inlet pressure of the coolant when it enters the heat dissipation pipe 12.

[0055] Figure 10 This is a three-dimensional structural diagram of the liquid-cooled radiator according to an embodiment of the present invention.

[0056] Accordingly, this utility model provides a liquid cooling radiator, including a cold head 500, a circulation pump, a cooling fan, and the aforementioned radiator module 503; The cold head 500 has a liquid inlet and a liquid outlet. The liquid inlet 5 and the liquid outlet 5 are connected by a first pipe 501, and the liquid outlet 3 and the liquid inlet 3 are connected by a second pipe 502. The cold head 500, the first pipe 501, the radiator and the second pipe 502 form a coolant circulation loop, and the circulation pump is installed in the coolant circulation loop according to a preset method.

[0057] In summary, this utility model provides a radiator module and a liquid-cooled heat sink. Compared with the prior art, without increasing the process cost, the separation of the input and output ports allows only a single flow of coolant in the heat pipe, which is beneficial to improving the heat dissipation efficiency of the radiator module. The radiator module has improved structural design, changed the assembly method, improved assembly convenience, maintenance convenience, and reduced processing costs, and has good economic applicability in practical applications.

The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model.
