Description

Technical Field

[0001] The present invention relates to the technical field of CPU, and in particular to a silent CPU cooling device. Background Art

[0002] As the computing and control core of the computer system, the CPU is the final execution unit for information processing and program execution. Since its creation, the CPU has made great progress in logical structure, operating efficiency and functional extension.

[0003] However, in the prior art, after long-term use, the existing computers are very likely to cause CPU heating. In order to reduce the heating of the CPU, most of the heat dissipation devices are installed to dissipate the heat of the CPU. Most of the existing heat dissipation devices are silent and have a good silent effect. However, most of these heat dissipation devices are fixed with bolts during installation or removal, and the bolts used are extremely small. If the operation is not careful, the bolts are easily lost, resulting in the heat dissipation device being unable to be installed and fixed. In addition, most of the fans of these heat dissipation devices are directly in contact with the wind, which is easy to cause dust to accumulate in the fans after long-term use. If they are not cleaned, the heat dissipation effect of the heat dissipation device is easily reduced. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art. By using a snap-on structure on the mainboard to replace the bolts used in the past, the situation that the heat dissipation device cannot be installed and fixed is avoided, and the heat dissipation device has the characteristics of easy installation and disassembly. In addition, by adding a filter to the heat dissipation device, the external wind is effectively filtered through the filter before contacting the fan, which greatly reduces the phenomenon of dust collection by the fan.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a silent CPU cooling device, comprising a mainboard, a concave block welded on the top of the mainboard, a button movably connected to the left side of the concave block, a first spring welded to the bottom of the inner wall of the concave block, a first limit plate welded to the top of the first spring, a CPU slot fixedly installed on the top of the mainboard, an anti-slip pad adhered to the top of the concave block, a radiator fixedly installed on the top of the concave block, a fixing rod welded to the bottom of the radiator, a sensor rod fixedly installed at the center position of the bottom of the radiator, a silicone grease pad adhered to the bottom of the sensor rod, a fixing block welded on the right side of the radiator, a fixing plate movably connected to the right side of the fixing block, a frame rotatably connected to the top of the fixing plate through a rotating shaft, and a filter screen fixedly installed inside the frame.

[0006] Preferably, a card rod is slidably penetrated inside the concave block, a second limit plate is welded to the left end of the card rod, a second spring is welded to the left side of the second limit plate, a first transmission rod is welded to the right side of the button, and the first transmission rod passes through the concave block, a first tension spring is sleeved on the outer wall of the first transmission rod, a third limit plate is welded to the right end of the first tension spring, the second transmission rod is slidably connected to the inside of the concave block, a fourth limit plate is welded to the bottom of the second transmission rod, and a second tension spring is welded to the bottom of the fourth limit plate.

[0007] Preferably, the internal thread of the fixing plate is connected with a bolt, a thread groove matching the thread on the bolt is opened on the right side of the fixing block, a rotation groove matching the bolt is opened on the right side of the fixing plate, and the bolt passes through the fixing plate.

[0008] Preferably, a slot matching the card rod is opened on the left side of the fixing rod, and a special-shaped slot matching the card rod is opened inside the concave block, and the special-shaped slots are all matched with the second limiting plate, the second spring, the first transmission rod, the first tension spring, the third limiting plate, the second transmission rod, the fourth limiting plate, and the second tension spring. The left end of the second spring is welded to the left side of the inner wall of the special-shaped slot, the left end of the first tension spring is welded to the left side of the inner wall of the special-shaped slot, the bottom end of the second tension spring is welded to the bottom surface of the inner wall of the special-shaped slot, and the left end of the first transmission rod is welded to the right side of the button.

[0009] Preferably, a first sliding groove matching with the second transmission rod is formed at the bottom of the clamping rod, and a second sliding groove matching with the first transmission rod is formed at the left side of the second transmission rod.

[0010] Preferably, the bottom of the fixing rod contacts the top of the first limiting plate, and the bottom of the silicone pad contacts the CPU in the CPU slot.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, by pressing a button, the clamping rod moves and shrinks into the inside of the concave block. After pressing the button, the fixing rod at the bottom of the radiator is inserted into the groove at the top of the concave block, so that the fixing rod is not blocked by the clamping rod when inserted, which is conducive to the fixing rod being quickly inserted into the inside of the concave block, so that the radiator is quickly installed and fixed to the mainboard. After releasing the button, since the inside of the concave block is respectively equipped with a first tension spring, a second tension spring and a second spring corresponding to the first transmission rod, the second transmission rod and the clamping rod, the clamping rod is inserted into the clamping groove of the fixing rod, so that the concave block and the fixing rod are fixed, so that the radiator and the mainboard are fixed. By adding a buckle structure to the inside of the concave block, it is avoided that the operation is complicated when installing or disassembling the radiator and the mainboard, resulting in damage to the radiator or the mainboard due to careless operation, and the service life of the radiator and the mainboard is improved. After the radiator is fixed, the bottom of the radiator is convenient for contacting the top of the anti-slip pad, so that the radiator is prevented from shaking due to a violent collision when it is fixed on the mainboard, resulting in the radiator being forced to separate from the mainboard, resulting in the radiator and the mainboard being unable to operate normally.

[0013] 2. In the present invention, when in use, a filter is first installed inside the frame to prevent external wind from directly contacting the fan on the radiator for a long time when the radiator is in operation, which causes a large amount of dust to be generated on the outer surface of the fan over time. The fixing plates on both sides of the frame are rotated to make the fixing plates contact with the fixing blocks on the radiator. Then, bolts are inserted into the fixing plates and the bolts are rotated so that the threaded part of the bolts is rotated and inserted into the inner wall of the thread groove of the fixing block. The filter is fixed to the radiator by the bolts. When the radiator is in use, the external wind that contacts the fan is gas filtered by the filter, so that the dust stays on the filter, thereby improving the heat dissipation effect of the radiator and reducing the dust collection efficiency of the fan after long-term use of the radiator.
