Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation modules, in particular to a heat dissipation module with a shovel-tooth type heat dissipation fin structure. Background Technique

[0002] When a chip is working, it will generate a large amount of heat. If this heat cannot be dissipated in time, it will cause the chip temperature to be too high, thereby affecting the heat dissipation effect of the computer. In order to ensure the heat dissipation effect of the computer, the computer fan will automatically rotate at an accelerated speed, thereby generating noise. Therefore, one of the functions of notebook chip heat dissipation is to reduce the noise of the computer. Notebook chip heat dissipation is very important. It can not only ensure the normal operation of the chip, extend the service life of the chip, improve the stability of the computer, but also reduce the noise of the computer. Therefore, when using a notebook computer, a heat dissipation module composed of a heat sink, a heat pipe and a heat dissipation fan is usually used to dissipate heat from electronic components such as the CPU.

[0003] In the current process of dissipating heat from electronic components such as the CPU, stamping type heat dissipation fins are usually used. However, there are some deficiencies in the single-piece buckling structure of this type of heat dissipation fin. First of all, the single pieces are connected by buckling points, which may cause certain obstacles to heat conduction during the conduction process, thereby reducing the heat conduction efficiency and further affecting the heat dissipation effect. Secondly, the heat conduction in the X direction of this structure depends on other parts, which undoubtedly increases the complexity and cost of the system. Based on this, a heat dissipation module with a shovel-tooth type heat dissipation fin structure is proposed to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a heat dissipation module with a shovel-tooth type heat dissipation fin structure, which has the advantage of improving the heat conduction efficiency, and solves the problems of blocked heat conduction, poor heat dissipation effect of the single-piece buckling structure of the existing stamping type heat dissipation fin, and the heat conduction in the X direction depends on other parts, increasing the complexity and cost of the system.

[0005] To achieve the above object, the utility model provides the following technical solution: A heat dissipation module with a shovel-tooth type heat dissipation fin structure, including a heat pipe, a connecting plate is attached to the outer surface of the heat pipe, a heat sink is fixed on the front surface of the connecting plate, a heat dissipation fin is fixed on the outer surface of the heat pipe, a fan is fixed at the bottom of the heat dissipation fin, and a fixing mechanism is arranged in the connecting plate;

[0006] The fixing mechanism includes two groups of connecting rods, a fixing plate fixed on the back of the connecting rod, a starting component and a guiding component;

[0007] The starting component includes a rotating rod whose one end is rotatably connected to the left inner wall of the connecting plate through a bearing and one end penetrates to the outside of the connecting plate. A rotating handle is fixed to the right end of the rotating rod. First bevel gears are fixed on both the left and right sides of the outer surface of the rotating rod. Second bevel gears are meshed with both the upper and lower sides of the outer surface of the first bevel gear. A threaded rod is fixed to the inner wall of the axis of the second bevel gear. A moving block is threadedly connected to the outer surface of the threaded rod. A guide rod is fixed between the opposite sides of the left and right moving blocks.

[0008] Furthermore, the inside of the heat pipe is filled with copper powder filler and water. Two moving holes are opened on the back surface of the connecting plate. The moving holes are slidably connected to the connecting rod.

[0009] Furthermore, the back surface of the moving block is fixed to the front surface of the connecting rod.

[0010] Furthermore, the opposite sides of the upper and lower fixing plates are respectively attached to the upper and lower sides of the heat pipe.

[0011] Furthermore, a through hole rotatably connected to the rotating rod is opened on the right side of the connecting plate.

[0012] Furthermore, the upper and lower groups of the threaded rods are symmetrically arranged up and down with the center line of the connecting plate as the axis.

[0013] Furthermore, the guiding component includes two guiding chutes opened on the left and right sides of the inner cavity of the connecting plate. A guiding slider is slidably connected to the inner wall of the guiding chute.

[0014] Furthermore, the opposite sides of the left and right guiding sliders are respectively fixed to the opposite sides of the two moving blocks. The cross section of the guiding slider and the guiding chute is convex.

[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0016] 1. For the heat dissipation module with the shovel tooth type heat dissipation fin structure, the chip contacts the heat sink, conducts heat to the heat sink, and then transfers it to the heat pipe. After the copper powder filler and water in the heat pipe are heated, the water evaporates into gas to take away heat. At the same time, a pressure difference is generated in the internal cavity, causing the gas to actively flow to the heat dissipation area with a smaller pressure. The heat dissipation fins are connected to the heat dissipation area of the heat pipe. The fan blows the heat dissipation fins to take away the heat on their surfaces. The heat dissipation fins are integral and can conduct heat by themselves in the XYZ directions, accelerating the heat transfer speed and efficiency. Its shovel tooth type structure increases the heat dissipation area, enabling the heat to be dissipated faster. In a certain space, the single-piece spacing of the heat dissipation fins is smaller and the number of pieces is more, making full use of the space and improving the heat dissipation effect. Compared with the traditional single-piece stamping type heat dissipation fins, the heat dissipation fins with the shovel tooth structure reduce the dependence on other parts and simplify the overall structure.

[0017] 2. For the heat dissipation module with the shovel-tooth type heat dissipation fin structure, when the rotating handle is rotated, the rotating rod is driven to rotate, so that the first bevel gear drives the second bevel gear to rotate. Since the threaded rod on the inner wall of the axis of the second bevel gear is threadedly connected to the moving block, when the threaded rod rotates with the second bevel gear, the moving block will move on the threaded rod. A guide rod is fixed between the left and right moving blocks to ensure stable movement. The connecting rod on the back of the moving block is connected to the fixed plate. When the moving block moves, the fixed plate will also move accordingly, so as to realize the fixation and separation of the heat pipe and the heat sink. In the guiding assembly, the guiding slider is fixed on the side of the moving block and is slidably connected to the guiding chutes on the left and right sides of the inner cavity of the connecting plate, providing guidance for the moving block to ensure its stable movement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , Figure 3 and Figure 4, A heat dissipation module with a shovel-tooth type heat dissipation fin structure in this embodiment includes a heat pipe 1. The inside of the heat pipe 1 is in a vacuum state, containing copper powder filler and water. A connecting plate 2 is attached to the outer surface of the heat pipe 1. A heat sink 3 is fixed to the front of the connecting plate 2. A heat dissipation fin 4 is fixed to the outer surface of the heat pipe 1. A fan 5 is fixed to the bottom of the heat dissipation fin 4. A fixing mechanism 6 is provided inside the connecting plate 2. A chip is attached to the front of the heat sink 3.

[0025] It should be noted that the chip conducts heat to the heat sink 3 and then transfers it to the heat pipe 1. The water in the heat pipe 1 evaporates into gas to take away heat. The gas flows to the heat dissipation area. The heat dissipation fin 4 is connected to the heat dissipation area of the heat pipe 1. The fan 5 blows the heat dissipation fin 4 to take away the heat on its surface. As a whole through the heat dissipation fin 4, it can conduct heat by itself. The shovel-tooth type structure increases the heat dissipation area, reduces the dependence on other parts, simplifies the overall structure, and can also fix the connection of heat pipes 1 and heat sinks 3 with different sizes through the fixing mechanism 6.

[0026] Please refer to Figures 1 to 4 , In order to fix the connection of heat pipes 1 and heat sinks 3 with different sizes, the fixing mechanism 6 in this embodiment includes two groups of connecting rods 608, a fixing plate 609 fixed to the back of the connecting rod 608, a starting component, and a guiding component. The starting component includes a rotating rod 601 whose one end is rotatably connected to the left inner wall of the connecting plate 2 through a bearing and one end penetrates to the outside of the connecting plate 2. A through hole rotatably connected to the rotating rod 601 is opened on the right side of the connecting plate 2. A rotating handle 602 is fixed to the right end of the rotating rod 601. First bevel gears 603 are fixed to both the left and right sides of the outer surface of the rotating rod 601. Second bevel gears 604 are engaged with both the upper and lower sides of the outer surface of the first bevel gear 603. A threaded rod 605 is fixed to the inner wall of the center of the second bevel gear 604. The upper and lower two threaded rods 605 are symmetrically arranged up and down with the center line of the connecting plate 2 as the axis. A moving block 606 is threadedly connected to the outer surface of the threaded rod 605. A guiding rod 607 is fixed between the opposite sides of the left and right two moving blocks 606. By rotating the rotating handle 602, the rotating rod 601 is driven to rotate, so that the first bevel gear 603 drives the second bevel gear 604 to rotate, and then the threaded rod 605 rotates to realize the movement of the moving block 606, thereby driving the fixing plate 609 to move, realizing the fixing and separation of the heat pipe 1 and the heat sink 3. The setting of the guiding rod 607 ensures the stability of the movement of the moving block 606.

[0027] Among them, two moving holes are opened on the back of the connecting plate 2. The moving holes are slidably connected to the connecting rods 608. The back of the moving block 606 is fixed to the front of the connecting rod 608. The opposite sides of the upper and lower two fixing plates 609 are respectively attached to the upper and lower sides of the heat pipe 1, so that the fixing plate 609 can move stably, thereby better fixing the heat sink 3 and the fixed heat pipe 1.

[0028] Meanwhile, the guiding component includes two guiding chutes 611 formed on the left and right sides inside the connecting plate 2. The inner walls of the guiding chutes 611 are slidably connected with guiding sliders 610. The opposite sides of the left and right guiding sliders 610 are respectively fixed to the opposite sides of the two moving blocks 606. The guiding sliders 610 and the guiding chutes 611 are convex in cross-section, providing guidance for the guiding sliders 610 to ensure the stability of the moving blocks 606 during movement.

[0029] The working principle of the above embodiment is as follows:

[0030] (1) Through the contact between the chip and the heat sink 3, the heat is conducted to the heat sink 3. Through the heat equalization effect of the heat sink 3, the heat is evenly distributed and better contacts with the chip, improving the heat conduction efficiency. The heat of the heat sink 3 is further conducted to the heat pipe 1. After the copper powder filler and water inside the heat pipe 1 are heated, the water evaporates into gas, taking away the heat. At the same time, a pressure difference is generated in the internal cavity, and the gas actively flows to the heat dissipation area with lower pressure. The heat dissipation fins 4 are connected to the heat dissipation area of the heat pipe 1, and the fan 5 blows the heat dissipation fins 4, so that the heat on their surfaces is taken away. Since the heat dissipation fins 4 are an integral body, they can conduct heat by themselves in the XYZ directions, improving the speed and efficiency of heat transfer. Through the structure of the shovel-tooth type heat dissipation fins 4, the heat dissipation area is increased, enabling the heat to be dissipated faster. At the same time, in a certain space, the single-piece spacing between the heat dissipation fins 4 is smaller and the number of pieces is more, making full use of the space and improving the heat dissipation effect. Compared with the traditional single-piece stamping type heat dissipation fins, the shovel-tooth structure heat dissipation fins 4 reduce the dependence on other parts and simplify the overall structure. Then, in the heat dissipation area, the gas inside the heat pipe 1 is cooled and turns into liquid, and the liquid flows back to the heating area through the internal filler (copper powder), thus forming a closed loop of heat conduction. The overall heat dissipation effect of this heat dissipation module is better, which can effectively reduce the temperature of the device and improve its stability and reliability.

[0031] (2) Meanwhile, it is also possible to rotate the turning handle 602, causing the rotating rod 601 to rotate accordingly. When the rotating rod 601 rotates, the first bevel gear 603 drives the second bevel gear 604 to rotate. The inner wall of the axis of the second bevel gear 604 is fixed with a threaded rod 605, and the threaded rod 605 is threadedly connected to the moving block 606. When the second bevel gear 604 rotates, the threaded rod 605 rotates accordingly, causing the moving block 606 to move on the threaded rod 605. A guide rod 607 is fixed between the opposite sides of the left and right moving blocks 606. The function of the guide rod 607 is to ensure that the moving block 606 remains stable during movement and does not rotate or deviate. The back surface of the moving block 606 is fixed to the front surface of the connecting rod 608. When the moving block 606 moves, the connecting rod 608 also moves accordingly, causing the fixing plate 609 to move accordingly, thereby realizing the fixation and separation of the heat pipe 1 and the heat sink 3. At the same time, in the guiding assembly, the guiding slider 610 is fixed to the side surface of the moving block 606, and the guiding slider 610 is slidably connected to the inner wall of the guiding chute 611. The guiding chute 611 is provided on the left and right sides of the inner cavity of the connecting plate 2, and its function is to provide guidance for the guiding slider 610 to ensure that the moving block 606 remains stable during movement. Based on the above principle, it can be seen that the fixing mechanism 6 of this heat dissipation module can closely fit and fix the fixing plate 609 and the heat pipe 1 without using complex tools or equipment, and can provide a stable fixing effect. At the same time, by adjusting the rotation angle of the turning handle 602, the moving distance of the fixing plate 609 can be controlled, so as to adapt to the connection and fixation of heat pipes 1 and heat sinks 3 of different sizes.
