When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0026] See also Figure 1 to Figure 7In an embodiment of the present invention, a notebook computer high-efficiency heat dissipation module includes: a base 1, a fan 3, a connector 4, an elastic locking structure, a clamping assembly, a speed regulating switch 23 and a follower assembly, so that when the CPU temperature of the notebook computer is too high, the heat dissipation fins 2 can transfer the temperature to the copper tube 22 to increase the pressure in the copper tube 22. At this time, under the action of the pressure, the sealing plug 19 is actuated, and the deflection rod 25 is rotated through the cooperation of the second convex shaft 24 and the retardation groove 2501, thereby increasing the actual gear position of the speed regulating switch 23, and driving the fan 3 to increase the rotation speed, improve its heat dissipation power, and ensure that when the CPU temperature of the notebook computer is too high, the heat can be removed in time to avoid CPU damage, as follows: The base 1 is detachably provided with a heat dissipation fin 2; The fan 3 is arranged on a side of the heat dissipation fin 2 away from the base 1; The connecting member 4 is disposed on the base 1, and an inclined groove 401 is disposed on the connecting member 4. The opening of the inclined groove 401 is inclined upward. After the first convex shaft 10 enters the end of the inclined groove 401, the heat dissipation fin 2 can make a circular motion with the first convex shaft 10. The elastic locking structure is installed on the base 1, and the first protruding shaft 10 arranged at the end of the heat dissipation fin 2 is adapted to the connecting member 4 and the elastic locking structure; The elastic locking structure comprises a follower 5 and a bracket 6 arranged on the base 1, the follower 5 is provided with a guide groove 501, and the guide groove 501 is slidably connected with a guide portion 601 arranged on the bracket 6; The elastic locking structure further includes a support kit disposed between the follower 5 and the bracket 6, the support kit including a transverse shaft 7 connected to the bracket 6, the transverse shaft 7 is slidably connected to the follower 5, and a first cylindrical spring 8 is sleeved on the transverse shaft 7, one end of the first cylindrical spring 8 is connected to the bracket 6, and the other end is connected to the follower 5; The limiting portion 9 arranged at the end of the follower 5 is adapted to the first convex shaft 10, and the limiting portion 9 is formed with a first inclined guiding surface 901 and a limiting groove 902 on the side facing the connecting member 4, and the plane formed by the limiting groove 902 and the end of the inclined groove 401 is parallel to the base 1.

[0027] When in use, the base 1 is fixed to the motherboard of the laptop computer by bolts. At this time, it is necessary to first apply heat dissipation silicone grease to the bottom of the heat dissipation fin 2, and then make the first protrusion 10 at one end of the heat dissipation fin 2 move along the inclined groove 401, until the first protrusion 10 moves to the end of the inclined groove 401, and then drive the other end of the heat dissipation fin 2 to move. At this time, the heat dissipation fin 2 can make a circular motion with the end of the inclined groove 401 as the center of the circle, until the other end of the heat dissipation fin 2 abuts against the first inclined guide surface 901 on the limiting portion 9, and then press and heat dissipation. At this end of the fin 2, the first protrusion 10 can cooperate with the first inclined guide surface 901 to drive the limiting portion 9 to move. At this time, the follower 5 will move along the length direction of the guide portion 601 and compress the first cylindrical spring 8 until the first protrusion 10 moves into the limiting groove 902, thereby realizing the connection between the base 1 and the heat dissipation fin 2, so that after the base 1 is fixed to the motherboard of the laptop computer, the heat dissipation fin 2 can be quickly installed and disassembled, and it is convenient to quickly replace the heat dissipation silicone grease after it deteriorates due to long-term use.

[0028] Among them, a protrusion is formed between the first inclined guide surface 901 and the limiting groove 902, and the protrusion is located at the end of the limiting groove 902 away from the connecting member 4, so that after the first protruding shaft 10 enters the limiting groove 902, the first protruding shaft 10 can be separated from the limiting groove 902 by pulling the heat sink fin 2 upward, thereby realizing the disassembly of the heat sink fin 2.

[0029] Furthermore, since the plane formed by the limiting groove 902 and the end of the inclined groove 401 is parallel to the base 1, when the first protrusion 10 at one end of the heat sink fin 2 is stuck in the inclined groove 401 and the first protrusion 10 at the other end is stuck in the limiting groove 902, the heat sink fin 2 can remain parallel to the base 1, and ensure that the heat sink fin 2 is in contact with the CPU of the notebook computer, thereby achieving a more uniform heat exchange between the notebook CPU and the heat sink fin 2. On the one hand, it can improve the heat dissipation effect on the CPU, and on the other hand, it can make the CPU dissipate heat evenly and avoid local high temperature of the CPU.

[0030] Through the above-mentioned arrangement, the heat sink 2 and the base 1 can be quickly disassembled and installed, and the heat sink grease can be quickly replaced after it deteriorates due to long-term use. On the other hand, when the first protrusion 10 at one end of the heat sink fin 2 is stuck in the inclined groove 401 and the first protrusion 10 at the other end is stuck in the limit groove 902, the heat sink fin 2 can remain parallel to the base 1, and ensure that the heat sink fin 2 is in contact with the CPU of the notebook computer, thereby achieving a more uniform heat exchange between the notebook CPU and the heat sink fin 2, which can improve the heat dissipation effect of the CPU while making the CPU dissipate heat evenly, avoiding local high temperature of the CPU.

[0031] See also Figure 3 , Figure 5 The clamping assembly connects the heat sink fins 2 and the fan 3, and the clamping assembly includes an abutment structure and a locking member 17. The abutment structure cooperates with the locking member 17 to connect the heat sink fins 2 and the fan 3; The abutment structure includes a hysteresis member 11 connected to the end of the fan 3, a hysteresis chamber is formed in the hysteresis member 11, a connecting shaft 12 is installed in the hysteresis chamber, a telescopic plate 14 is slidably installed on the connecting shaft 12, and the telescopic plate 14 is adapted to the locking member 17; The connecting shaft 12 is sleeved with a second cylindrical spring 13, one end of the second cylindrical spring 13 is connected to the telescopic plate 14, and the other end is connected to the inner wall of the hysteresis chamber; The telescopic plate 14 is formed with a hook portion 15 capable of penetrating the inner wall of the hysteresis chamber, and a connecting plate 16 is provided at one end of the telescopic plate 14 away from the second cylindrical spring 13; The locking member 17 is in a “U”-shaped structure, and a second inclined guide surface 1702 is provided at one end of the locking member 17 away from the heat dissipation fins 2 . The hooking portion 15 is adapted to a locking groove 1701 provided on the locking member 17 .

[0032] When the heat sink fins 2 are installed in place, the fan 3 is made parallel to the heat sink fins 2, and the telescopic plate 14 is aligned with the locking member 17. At this time, the fan 3 is pressed downward to move, and the hook portion 15 at the end of the telescopic plate 14 can be retracted into the hysteresis member 11 and compress the second cylindrical spring 13 under the drive of the locking member 17. Subsequently, when the fan 3 abuts against the upper end of the heat sink fin 2, the hook portion 15 can enter the locking groove 1701 when the second cylindrical spring 13 releases its elastic potential energy, thereby fixing the fan 3 and the heat sink fin 2. When the connecting plate 16 is pressed, the telescopic plate 14 and the hook portion 15 can be retracted into the hysteresis member 11 again, and when the fan 3 is pulled upward, the fan 3 can be separated from the heat sink fin 2. Based on the above principle, the fan 3 and the heat sink fin 2 can be quickly replaced and connected.

[0033] Among them, since a second inclined guide surface 1702 is provided on the upper part of the locking member 17, the second inclined guide surface 1702 can guide the hooking portion 15 and facilitate the hooking portion 15 to enter the locking member 17, which has a certain anti-mistake effect and improves the portability of the fan 3 during installation.

[0034] Through the above arrangement, when the hook portion 15 cooperates with the locking groove 1701, the fan 3 and the heat dissipation fin 2 can be quickly connected and disassembled. At the same time, the second inclined guide surface 1702 has a guiding effect on the hook portion 15, thereby improving the portability of the fan 3 during installation and playing a fool-proof role.

[0035] See also Figure 3 , Figure 5~Figure 6 , the speed regulating switch 23 is arranged on the base 1 and is electrically connected to the fan 3; The follower assembly is connected to the heat sink fins 2, and the follower assembly can control the speed regulating switch 23 in real time according to the temperature of the heat sink fins 2. The follower assembly includes a sealed cylinder 18 mounted on the heat sink fins 2 and a copper tube 22 sealed with the heat sink fins 2, and the copper tube 22 is connected to the sealed cylinder 18; A sealing plug 19 is sealingly and slidably installed in the sealing cylinder 18, and a telescopic shaft 20 perpendicular to the sealing plug 19 is provided on the sealing plug 19, and the telescopic shaft 20 penetrates the sealing cylinder 18 and is slidably arranged; The telescopic shaft 20 is sleeved with a third cylindrical spring 21, one end of the third cylindrical spring 21 is connected to the sealing plug 19, and the other end is connected to the inner wall of the sealing cylinder 18; The follower assembly also includes a connecting structure connecting the telescopic shaft 20 and the speed control switch 23, and the connecting structure includes a second convex shaft 24 rotatably installed at one end of the telescopic shaft 20 away from the sealing plug 19 and a deflection rod 25 connected to the speed control switch 23, and the deflection rod 25 is provided with a retardation groove 2501 along its length direction, and the retardation groove 2501 is rollingly matched with the second convex shaft 24.

[0036] The copper tube 22, the sealed cylinder body 18 and the sealing plug 19 can form a closed chamber. At this time, when the CPU temperature of the laptop computer is too high, the temperature of the heat sink 2 will also rise, and the heat sink fin 2 will exchange heat with the copper tube 22, resulting in the temperature inside the copper tube 22 rising, thereby increasing the pressure in the copper tube 22, and then increasing the pressure of the closed chamber formed between the copper tube 22, the sealed cylinder body 18 and the sealing plug 19, and pushing the sealing plug 19 to move. When the sealing plug 19 moves, it can drive the second cam 24 to move away from the sealed cylinder body 18 along the length direction of the telescopic shaft 20, and the second cam 24 cooperates with the retardation groove 2501 to drive the deflection rod 25 to move, thereby changing the position of the deflection rod 25 relative to the speed control switch 23, so that the actual gear position of the speed control switch 23 increases, and drives the fan 3 to increase the rotation speed, improve its heat dissipation power, and ensure that when the CPU temperature of the laptop computer is too high, the heat can be removed in time to avoid CPU damage.

[0037] Through the above arrangement, when the CPU temperature of the laptop computer is too high, the heat sink fins 2 can transfer the temperature to the copper tube 22 to increase the pressure in the copper tube 22. At this time, under the action of the pressure, the sealing plug 19 is actuated, and through the cooperation of the second convex shaft 24 and the retardation groove 2501, the deflection rod 25 is rotated, thereby increasing the actual gear position of the speed control switch 23, and driving the fan 3 to increase the rotation speed, thereby improving its heat dissipation power, ensuring that when the CPU temperature of the laptop computer is too high, the heat can be removed in time to avoid CPU damage.

[0038] As an embodiment of the present invention, a method for using the laptop computer high-efficiency heat dissipation module is also proposed, comprising the following steps: Step 1: Fix the base 1 to the mainboard of the laptop computer with bolts; Step 2: Make the first protruding shaft 10 at one end of the heat sink fin 2 enter the inclined groove 401 in the connecting member 4, and then press the other end of the heat sink fin 2, at which time the other first protruding shaft 10 will cooperate with the elastic locking structure to fix the heat sink fin 2; Step 3: Connect the fan 3 and the heat sink fin 2 through the snap-fit ​​assembly; Step 4: When the CPU temperature of the notebook computer rises while the notebook computer is running, the follow-up component will be activated, thereby changing the actual gear position of the speed control switch 23 and adjusting the heat dissipation power of the fan 3.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
