Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation modules, in particular to a fin-separated heat dissipation module. Background Art

[0002] A fin-separated heatsink is a cooling design that includes a heat sink, heat pipes, cooling fins, and a fan. The heat sink (or heat sink for short) is the medium that comes into direct contact with the CPU. Heat generated by the CPU and GPU is first absorbed by the heat sink and then transferred to the fins via the heat pipes. This heat is ultimately exhausted by the fan, reducing the device's temperature.

[0003] Current heat dissipation modules are usually set up through welding supports or tight-fitting processes. Regardless of the design method used, the final product of the heat dissipation module is permanently fixed, so the final heat dissipation area of ​​the heat dissipation module is always the same. Therefore, when wanting to improve the heat dissipation efficiency of the heat dissipation module, it can only be controlled by changing the fan speed. This will result in limited heat dissipation efficiency of the heat dissipation module. In actual use, it cannot be effectively adjusted according to actual needs. Summary of the Invention

[0004] The purpose of the present invention is to provide a fin-separated heat dissipation module to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A fin-separated heat dissipation module comprises: a support bracket, a pressing frame elastically and slidably provided on the support bracket, the pressing frame being connected to a locking member provided on the support bracket via a positioning assembly, and when the pressing frame is pulled to slide relative to the support bracket, the positioning assembly cooperates with the locking member to lock the position of the pressing frame, thereby facilitating the disassembly and assembly of the heat dissipation fins on the support bracket;

[0007] The locking assembly is arranged on the heat dissipating fins and includes a locking structure and a trigger member. The locking structure includes a positioning member slidably arranged on the heat dissipating fins. When the trigger member is pressed downward, the positioning member will slide relative to the heat dissipating fins, thereby facilitating the disassembly and installation between the two groups of heat dissipating fins.

[0008] The fin-separated heat dissipation module as described above: the pressing frame is symmetrically provided with two groups of plug-in rods along the width direction of the supporting frame, the two groups of plug-in rods are respectively inserted into the plug-in tubes formed on the supporting frame, and the supporting frame is connected to the pressing frame through a first spring.

[0009] The fin-separated heat dissipation module as described above: there are two groups of positioning components, and the two groups of positioning components are respectively arranged on the plug-in rod, and each group of positioning components includes a fixed sleeve arranged on the plug-in rod, and a second spring is slidably arranged in the fixed sleeve, one end of the second spring abuts against the bottom of the fixed sleeve, and the other end abuts against the telescopic rod slidably arranged in the fixed sleeve, and a pulley is rotatably installed on the end of the telescopic rod away from the second spring.

[0010] As described above, the fin-separated heat dissipation module: the locking member includes a positioning plate arranged on the support bracket, and the positioning plates are symmetrically arranged in two groups along the width direction of the support bracket, and each group of the positioning plates is formed with a horizontal plane, a first positioning groove and a second positioning groove.

[0011] The fin-separated heat dissipation module as described above: the trigger member includes a pressing plate that is slidably connected to the heat dissipation fins, and a connecting rod is provided on the pressing plate. The connecting rods are symmetrically arranged in two groups along the length direction of the pressing plate, and the two groups of connecting rods are provided with a wedge block at one end away from the pressing plate.

[0012] The fin-separated heat dissipation module as described above: the locking structure includes a positioning cylinder arranged on the heat dissipation fin, and the positioning cylinder is symmetrically arranged in two groups along the length direction of the heat dissipation fin. A placement cavity and a positioning cavity are formed on the two groups of positioning cylinders. A third spring is slidingly arranged in the placement cavity, and one end of the third spring abuts against the bottom of the placement cavity, and the other end abuts against the positioning member.

[0013] As described above, in the fin-separated heat dissipation module, the positioning member includes a locking rod slidably arranged in the positioning cylinder, and the locking rod is provided with an adapting groove adapted to the wedge block.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] By providing a positioning component and utilizing the cooperation between the positioning component and the pressing frame, the installation position of the support bracket can be expanded. When the installation position of the support bracket is expanded to the maximum, the position of the pressing frame will be fixed relative to the support bracket, thereby facilitating the user to add or remove the heat sink fins according to actual heat dissipation needs. After the addition or removal is completed, the pressing frame is pushed, and the cooperation between the positioning component and the first spring can make the heat sink fins fit more tightly. The heat sink fins that fit together are equivalent to increasing the area of ​​the heat sink fins, thereby improving the heat dissipation speed of the entire device to the CPU.

[0016] At the same time, by arranging a clamping assembly on the heat dissipation fins and utilizing the cooperation between the clamping assemblies, a fixed connection between the two sets of heat dissipation fins can be achieved, so that the heat dissipation fins cannot move up and down on the support bracket;

[0017] In combination with the above, the heat dissipation fins can be freely added or removed, thereby making the heat dissipation speed of the entire device adjustable and suitable for various needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0029] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0030] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0031] See also Figures 1-9 In an embodiment of the present invention, a fin-separated heat dissipation module includes:

[0032] A support bracket 1 is provided with a pressing frame 5 which is elastically slidably provided on the support bracket 1. The pressing frame 5 is connected to a locking member provided on the support bracket 1 through a positioning assembly. When the pressing frame 5 is pulled to slide relative to the support bracket 1, the positioning assembly cooperates with the locking member to lock the position of the pressing frame 5, thereby facilitating the disassembly and assembly of the heat dissipation fins 3 of the support bracket 1;

[0033] Preferably, see Figure 1 、 Figure 2 、 Figure 3 The fan 2 is mounted on the support bracket 1 and is fixedly connected to the support bracket 1 by bolts or welding. Guardrails are provided on the left and right sides of the support bracket 1 to block the fan 2 and the heat dissipation fins 3 on both sides, thereby allowing the heat dissipation fins 3 to slide left and right on the support bracket 1.

[0034] In particular, a locking groove 201 is provided on the side of the fan 2 facing the pressing frame 5. The locking groove 201 cooperates with the locking structure provided on the heat dissipation fin 3 to achieve relative fixation between the heat dissipation fin 3 and the fan 2. When the CPU and GPU generate heat during operation, the heat will be transferred to the heat dissipation fin 3, and then the heat will be discharged under the action of the fan 2, thereby reducing the temperature of the device.

[0035] The pressing frame 5 is symmetrically provided with two groups of plug-in rods 6 along the width direction of the support frame 1. The two groups of plug-in rods 6 are respectively inserted into the plug-in cylinders 101 formed on the support frame 1, and the support frame 1 is connected to the pressing frame 5 via a first spring 4.

[0036] For details, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , the above-mentioned first spring 4 is symmetrically arranged in two groups along the width direction of the support bracket 1, and one end of each group of the first spring 4 is fixedly connected to the support bracket 1, and the other end is fixedly connected to the pressing frame 5;

[0037] In particular, the above-mentioned first spring 4 is always in a pulled-up state. In the initial state, the telescopic rod 10 is immersed in the plug-in tube 101. At this time, the distance between the pressing frame 5 and the fan 2 is the smallest, and the support frame 1 and the pressing frame 5 can only accommodate the fan 2 and a group of heat dissipation fins 3. When the heat dissipation speed of the equipment needs to be improved, the heat dissipation speed can be accelerated by adding heat dissipation fins 3 between the support frame 1 and the pressing frame 5. Specifically, when the heat dissipation fins 3 are installed, when the pressing frame 5 is pulled in the direction away from the fan 2 to the end of the stroke, the pressing frame 5 will be fixed relative to the support frame 1 under the action of the positioning component. At this time, the distance between the pressing frame 5 and the fan 2 is expanded to the maximum, which can facilitate the user to install the heat dissipation fins 3.

[0038] For further information, see Figure 3 、 Figure 4 、 Figure 5 , the positioning assembly is provided with two groups, and the two groups of positioning assemblies are respectively provided on the plug-in rod 6, and each group of positioning assemblies includes a fixed sleeve 8 provided on the plug-in rod 6, and a second spring 9 is slidably provided in the fixed sleeve 8, and one end of the second spring 9 abuts against the bottom of the fixed sleeve 8, and the other end abuts against the telescopic rod 10 slidably provided in the fixed sleeve 8, and the telescopic rod 10 is rotatably installed with a pulley at one end away from the second spring 9;

[0039] The locking member includes a positioning plate 7 provided on the support bracket 1. The positioning plates 7 are symmetrically provided in two groups along the width direction of the support bracket 1. Each group of the positioning plates 7 is formed with a horizontal surface 701, a first positioning groove 702, and a second positioning groove 703.

[0040] Preferably, see Figure 5The above-mentioned second spring 9 is always in a compressed state. The second spring 9 in the compressed state pushes the telescopic rod 10 to have a tendency to move toward the positioning plate 7. In the initial state, that is, when the distance between the pressing frame 5 and the fan 2 is the smallest, the pulley is combined with the first positioning groove 702. At this time, only one set of fans 2 can be placed on the support bracket 1. When the heat dissipation fins 3 are installed, the pressing frame 5 is pulled toward a position away from the fan 2. During this process, the pulling amount of the first spring 4 will gradually increase, and the plug-in rod 6 will slide in the plug-in tube 101. At the same time, the pulley will slide along the horizontal plane 701 until the pulley is combined with the second positioning groove 703. When the second spring 9 is closed, the second spring 9 will quickly release part of its elastic potential energy to make the pulley engage with the second positioning groove 703, thereby fixing the position of the pressing frame 5. (It should be noted that the elastic potential energy stored in the second spring 9 is always greater than the elastic potential energy possessed by the first spring 4 when it is pulled up, so that when the pulley is engaged with the second positioning groove 703, the first spring 4 connecting the support frame 1 and the pressing frame 5 will not cause the pulley to disengage from the second positioning groove 703, thereby keeping the position between the pressing frame 5 and the support bracket 1 relatively fixed.) At this time, the distance between the pressing frame 5 and the fan 2 is maximized, making it convenient for the user to install the heat dissipation fins 3.

[0041] When a group of heat dissipation fins 3 are installed, the pressing frame 5 is pushed toward the fan 2, and the pulley will separate from the second positioning slot 703. When the pulley is engaged with the horizontal plane 701, the retraction of the first spring 4 will drive the pressing frame 5 to move toward the fan 2 until the pressing frame 5 is in contact with the heat dissipation fins 3, and the pressing frame 5 stops moving. At this time, the first spring 4 is still in a pulled-up state. The first spring 4 in the pulled-up state squeezes the heat dissipation fins 3, which makes the heat dissipation fins 3 and the fan 2 fit more tightly, which can improve the heat dissipation efficiency. When multiple groups of heat dissipation fins 3 are installed on the support bracket 1, the pulled-up first spring 4 can still make the heat dissipation fins 3 fit more tightly. The heat dissipation fins 3 that are stuck together are equivalent to increasing the area of ​​the heat dissipation fins 3, thereby increasing the heat dissipation speed of the device as a whole to the CPU. At the same time, under the action of the first spring 4, the heat dissipation fins 3 will not move back and forth on the support bracket 1.

[0042] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 A fin-separated heat dissipation module further includes: a locking assembly, the locking assembly being arranged on the heat dissipation fin 3, including a locking structure and a triggering member, the locking structure including a positioning member slidably arranged on the heat dissipation fin 3, and when the triggering member is pressed downward, the positioning member slides relative to the heat dissipation fin 3, thereby facilitating the disassembly and installation between the two groups of the heat dissipation fin 3;

[0043] The trigger member includes a pressing plate 11 that is slidably connected to the heat dissipation fins 3. The pressing plate 11 is provided with connecting rods 14. Two groups of connecting rods 14 are symmetrically provided along the length direction of the pressing plate 11. The ends of the two groups of connecting rods 14 away from the pressing plate 11 are both provided with wedge blocks 15.

[0044] The locking structure includes a positioning tube 13 provided on the heat dissipation fin 3. The positioning tube 13 is symmetrically provided in two groups along the length direction of the heat dissipation fin 3. Both groups of the positioning tubes 13 are formed with a placement cavity 1301 and a positioning cavity 1302. A third spring 16 is slidably provided in the placement cavity 1301. One end of the third spring 16 abuts against the bottom of the placement cavity 1301, and the other end abuts against the positioning member.

[0045] The positioning member includes a locking rod 12 slidably disposed in the positioning cylinder 13 , and the locking rod 12 is provided with an adapting groove 1201 adapted to the wedge block 15 ;

[0046] Preferably, see Figure 8 、 Figure 9 , the pressing plate 11 is arranged on the heat dissipation fin 3, and the wedge block 15 is arranged into a "right-angled trapezoidal" structure, such as Figure 9 As shown, the wedge block 15 includes an inclined surface 1501. Correspondingly, the above-mentioned adapting groove 1201 is also provided with a "right-angled trapezoidal" structure. For details, please refer to Figure 9 The third spring 16 is always in a compressed state. The compressed third spring 16 pushes the locking rod 12 away from the positioning cavity 1302. At this time, the contact and compression between the inclined surface of the adapting groove 1201 and the inclined surface 1501 forces the wedge block 15 to face the bottom surface of the pressing plate 11 and fit the heat sink fin 3.

[0047] When installing the first set of heat sink fins 3, hold the heat sink fins 3 and press the pressing plate 11 downward. At this time, the inclined surface 1501 will squeeze the inclined surface of the adapter groove 1201, and then force the locking rod 12 to further squeeze the third spring 16 until the heat sink fins 3 are placed on the support bracket 1. Then release the pressing plate 11, and the third spring 16 releases the elastic potential energy to push the locking rod 12 to combine with the locking groove 201. At this time, the heat sink fins 3 are fixed to the fan 2 and cannot move up and down. When the second set of heat sink fins 3 is then installed, the locking rod 12 of the second set of heat sink fins 3 will combine with the positioning cavity 1302 of the previous set of heat sink fins 3, and then a fixed connection between the two sets of heat sink fins 3 is realized, thereby increasing the heat dissipation area of ​​the heat sink fins 3.
