Description

Technical Field

[0001] This utility model relates to the field of auxiliary heat dissipation devices, and in particular to a computer heat dissipation device. Background Technology

[0002] Computer cooling devices are used to dissipate heat generated inside a computer. Their main function is to absorb and dissipate the heat generated by computer components into or outside the computer case to ensure the normal operating temperature of the computer hardware.

[0003] Patent specification CN222125710U discloses a portable computer auxiliary cooling device. The technical solution includes: a support body with a T-shaped groove in the lower middle; a T-shaped key connected inside the T-shaped groove; a guide plate fixedly connected to the T-shaped key; a fan frame rotatably connected to the left side of the guide plate; a horizontal plate fixedly connected to the middle of the fan frame; and a fan rotatably connected inside the horizontal plate. This invention, through the coordinated arrangement of the support body, fan, and guide plate, can better accommodate different computer models and meet the cooling needs of various computers. Through the interaction of springs and baffles, and the inclusion of a gearbox, when the portable computer is placed on top of the support body, it can be better secured, preventing slippage and allowing the portable computer to be conveniently positioned in a centered position for easy use.

[0004] However, in implementing the relevant technology, the aforementioned portable computer auxiliary cooling device has the following problems: by removing the support column at the rear of the stand body from the support column slot and placing it in any adjustment slot on the bottom plate, and then placing the computer on top of the stand body to facilitate computer cooling, the stand body only has four adjustment slots, which limits the adjustable position of the fan, and each adjustment requires separating the computer from the stand body. For users who need to frequently adjust the angle or position of the computer, this operation is particularly cumbersome and may cause accidental damage to the computer. In view of this, a computer cooling device is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a computer cooling device.

[0007] As a further description of the above technical solution: the upper and lower ends of the first hollow rod are slidably connected to the hollow plate, the outer side of the pressure plate and the outer side of the buckle are both in contact with the inside of the hollow plate, the upper end of the buckle is in contact with the inside of the hollow plate, and the left end of the slide rail is slidably connected to the right end of the fan.

[0008] As a further description of the above technical solution: a protrusion is provided at the left end of the slide rail, and a groove is provided at the right end of the fan. The cross-sectional area of ​​the groove matches the cross-sectional area of ​​the protrusion at the left end of the slide rail, so that the fan can slide at the left end of the slide rail to adjust the distance between the front and rear fans, so as to adapt to different models of computers for heat dissipation.

[0009] As a further description of the above technical solution: the threads on the front and rear sides of the rotatable connection between the bidirectional threaded rod and the connecting rod are opposite in direction. The connecting block has through circular grooves at both ends, and the inner wall of the circular groove has an internal thread that matches the external thread of the bidirectional threaded rod. By rotating the rotating wheels on the front and rear sides, the connecting blocks on the front and rear sides slide in opposite directions along the bidirectional threaded rod at the same time, so that the fan can be adapted to different models of computers for heat dissipation.

[0010] As a further description of the above technical solution: the upper end of the first hollow rod is provided with a slot, and the cross-sectional area of ​​the slot matches the cross-sectional area of ​​the buckle. The upper end of the hollow plate is provided with several horizontally evenly arranged positioning slots, and the cross-sectional area of ​​the positioning slots matches the cross-sectional area of ​​the buckle. This allows the buckle to engage with the positioning slots, thereby fixing and adjusting the left and right positions of the fan and improving the versatility of the device.

[0011] As a further description of the above technical solution: a second spring is fixedly connected inside the slide rail, a fixing block is fixedly connected to the end of the second spring away from the slide rail, a clamping plate is fixedly connected to the front end of the fixing block, a third spring is fixedly connected to the lower end inside the hollow plate, a bottom support plate is fixedly connected to the end of the third spring away from the hollow plate, a rotating plate is rotatably connected to the upper end of the clamping plate, and a pin is fixedly connected to the outer side of the clamping plate, so that the computer on the upper part of the hollow plate can be clamped and fixed by the clamping plate and the bottom support plate, preventing the computer from slipping off the upper part of the hollow plate and causing damage to the computer.

[0012] As a further description of the above technical solution: the lower end of the hollow plate has a hollow structure, and the third spring and the bottom plate are both inside the hollow structure. By pulling the handle at the upper end of the bottom plate, it is easy to clamp and fix the bottom plate to the computer, thereby improving the user experience.

[0013] This utility model has the following beneficial effects:

[0014] The computer cooling device designed in this utility model uses a combination of a bidirectional threaded rod and a connecting rod to adjust the distance between the two fans inside the hollow plate. This allows the fans to move and be fixed in the left and right directions within the hollow plate. It can be customized according to different computer cooling conditions, thereby enhancing the adaptability of the cooling system, extending the computer's lifespan, and reducing the risk of hardware damage due to overheating.

[0015] This utility model designs a computer cooling device that, through the coordinated design of clamping blocks and a base plate, allows the computer to be fixed inside the clamping blocks by pulling the clamping blocks on both the front and rear sides and under the tension of a second spring. Then, the base plate is clamped to one side of the computer, ensuring that the computer will not slip due to accidental contact during use, thereby avoiding damage to the computer or loss of data caused by slippage. The design of the rotating plate allows the computer to be clamped by inserting one end of the rotating plate into the pin when the rotating plate blocks the computer port, thus improving the convenience of the device.

[0028] As a further implementation of the above technical solution: the upper and lower ends of the first hollow rod 9 are slidably connected to the hollow plate 1, the outer side of the pressure plate 11 and the outer side of the buckle 12 are both in contact with the inside of the hollow plate 1, the upper end of the buckle 12 is in contact with the inside of the hollow plate 1, and the left end of the slide rail 4 is slidably connected to the right end of the fan 8.

[0029] As a further implementation of the above technical solution: a protrusion is provided on the left end of the slide rail 4, and a groove is provided on the right end of the fan 8. The cross-sectional area of ​​the groove matches the cross-sectional area of ​​the protrusion provided on the left end of the slide rail 4, so that the fan 8 can slide on the left end of the slide rail 4 to adjust the distance between the front and rear fans 8, so as to adapt to different models of computers for heat dissipation.

[0030] As a further implementation of the above technical solution: the threads on the front and rear sides of the rotatable connection between the bidirectional threaded rod 5 and the connecting rod 3 are opposite in direction. The connecting block 7 has through circular grooves at both ends, and the inner wall of the circular groove has an internal thread that matches the external thread of the bidirectional threaded rod 5. By rotating the rotating wheels 6 on the front and rear sides, the connecting blocks 7 on the front and rear sides slide in opposite directions along the bidirectional threaded rod 5 at the same time, so that the fan 8 can be adapted to different models of computers for heat dissipation.

[0031] As a further implementation of the above technical solution: the upper end of the first hollow rod 9 is provided with a slot, and the cross-sectional area of ​​the slot matches the cross-sectional area of ​​the buckle 12. The upper end of the hollow plate 1 is provided with several horizontally evenly arranged positioning slots, and the cross-sectional area of ​​the positioning slots matches the cross-sectional area of ​​the buckle 12. This allows the buckle 12 to engage with the positioning slots, thereby fixing and adjusting the left and right positions of the fan 8 and improving the versatility of the device.

[0032] As a further implementation of the above technical solution: a second spring 15 is welded inside the slide rail 4, a fixing block 16 is welded to the end of the second spring 15 away from the slide rail 4, a clamping plate 17 is welded to the front end of the fixing block 16, a third spring 18 is welded to the lower end inside the hollow plate 1, a bottom plate 19 is welded to the end of the third spring 18 away from the hollow plate 1, a rotating plate 20 is rotatably connected to the upper end of the clamping plate 17, and square slots are provided at both ends of the rotating plate 20. The cross-sectional area of ​​the square slots matches the cross-sectional area of ​​the plug at the upper end of the pin 21. The pin 21 is welded to the outside of the clamping plate 17, so that the computer at the upper end of the hollow plate 1 can be clamped and fixed by the clamping plate 17 and the bottom plate 19, preventing the computer from slipping off the upper end of the hollow plate 1 and causing damage to the computer.

By pulling the handle at the upper end of the bottom plate 19, it is easy to clamp and fix the bottom plate 19 to the computer, thereby improving the user experience.

[0034] Working principle:

[0035] When using this utility model, place the computer on top of the dustproof mesh 2, rotate the hollow plate 1, rotate the shaft 13 to support the hollow plate 1 with the support plate 14, and then rotate the wheel 6 according to the computer model. The wheel 6 drives the bidirectional threaded rod 5 to rotate. Since the right end of the fan 8 is slidably connected to the slide rail 4, the bidirectional threaded rod 5 can drive the outer connecting block 7 to move horizontally. Since the threads of the bidirectional threaded rod 5 on both sides of the connecting rod 3 are opposite, rotating the bidirectional threaded rod 5 can drive the two fans 8 to slide in opposite directions. Then press the pressure plate 11 inside the first hollow rod 9. The pressure plate 11 drives the buckle 12 to move downward and compress the first spring 10. At the same time, the buckle... The upper end of plate 12 is disengaged from the hollow plate 1, allowing the fan 8 to move left and right within the hollow plate 1. Pulling the clamping plate 17 stretches the second spring 15 and the fixing block 16, clamping the computer securely against the inside of the clamping plate 17. Then, pulling the handle at the top of the base plate 19 stretches the third spring 18, thus clamping the computer and preventing it from falling off and causing damage. When the rotating plate 20 clamps and secures the computer and blocks the computer port, press the pin 21 to retract the plug into the port. Rotate the blocking rotating plate 20 to a horizontal angle, then insert the plug into the square groove set in the rotating plate 20. Use another rotating plate 20 to clamp and secure the computer, improving the convenience of the device.
