Description

Technical Field

[0001] The utility model relates to the technical field of CPU heat dissipation, in particular to a server CPU heat dissipation device. Background Art

[0002] A heat sink is a device for dissipating heat from heat-prone electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the shape of plates, sheets, or multiple sheets. For example, a CPU in a computer requires a relatively large heat sink, and power tubes, line tubes, and power amplifier tubes in a television all require heat sinks. A large number of heat sinks are usually required in a computer case, but the dustproof ability of existing cases is generally average. After being used for a long time, the heat dissipation components in the computer will be covered with or adhered to a layer of dust, especially the cooling fan on the CPU heat dissipation component. Since the cooling fan of the existing CPU heat dissipation device is not easy to disassemble, it is usually difficult to clean the dust accumulated in the fan blades and the fan blade mounting frame, which is very likely to affect the rotation of the fan blades for a long time, thereby reducing the heat dissipation performance of the CPU heat dissipation device. For this reason, a CPU heat dissipation device is specifically proposed.

[0003] After searching, it is found that a CPU heat dissipation device is disclosed in a Chinese patent document [Application No.: CN202321162934.6]. This CPU heat dissipation device includes a heat dissipation fin group, a heat dissipation fan mounting frame, and a heat dissipation fan. The bottom of the heat dissipation fin group is connected and mounted with a CPU heat conduction base, and a heat conduction pipe is connected and mounted on the side of the CPU heat conduction base. The heat dissipation fan mounting frame is fixedly mounted on the right side of the heat dissipation fin group, a limit sliding button is movably mounted on the surface of the heat dissipation fan mounting frame, a limit clamping column is connected and mounted on the side of the limit sliding button, and a reset spring is fixedly mounted on the side of the limit clamping column, and a pop-up plate is movably mounted inside the heat dissipation fan mounting frame.

[0004] The device disclosed in this patent can pop out the cooling fan installation frame that has been released from the limit by setting a pop-up plate, but at this time the cooling fan installation frame will pop out directly to the outside, and it is difficult to limit the pop-up position of the cooling fan installation frame. Therefore, the cooling fan installation frame is prone to falling, and the vibration received by the cooling fan installation frame when it falls is likely to cause damage to the cooling fan, etc. At the same time, when the cooling fan is in use, dust is likely to adhere to the inner wall of the cooling fan installation frame and the cooling fan, thereby affecting the cooling effect of the subsequent use of the device.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-8 As shown, a server CPU heat dissipation device includes a heat conduction mechanism 1. A limit frame 2 is fixedly connected to the surface of the heat conduction mechanism 1. A slot 3 is opened at the top of the limit frame 2. A chute 4 is opened on the surface of the limit frame 2. An installation bracket 5 is detachably connected inside the slot 3. A short column 6 is fixedly connected to the surface of the installation bracket 5. The surface of the short column 6 is in contact with the inner wall of the slot 3. A positioning mechanism 7 is arranged inside the slot 3. One end of the positioning mechanism 7 is fixedly connected to a pulling plate 8. A storage mechanism 10 is installed on the surface of the pulling plate 8. A dust-proof net plate 11 is detachably connected inside the storage mechanism 10. A cylindrical groove and a groove 13 are opened on the surface of the installation bracket 5. A card slot 12 is opened on the inner wall of the groove 13. A flap 14 is rotatably connected inside the groove 13. An extension rod 16 is fixedly connected to the inner wall of the cylindrical groove. One end of the extension rod 16 is installed with a cooling fan 17. An auxiliary mechanism 15 is arranged inside the cylindrical groove. A storage groove is opened at the bottom of the inner wall of the limit frame 2. An ejection mechanism 18 is installed inside the storage groove. Rectangular grooves are opened on both sides of the inner wall of the storage groove.

[0029] The heat conduction mechanism 1 includes heat dissipation fins, a heat conduction tube fixedly penetrating the heat dissipation fins, and a heat conduction plate in contact with the server CPU. The heat conduction plate conducts the heat of the CPU to the heat dissipation fins through the heat conduction tube, so as to facilitate the dissipation of the CPU heat.

[0030] When the locking cam 72 is in the closed position, the locking cam 73 is in the closed position, and the locking cam 73 is in the closed position, so that the locking cam 73 is in the open position and the locking cam 73 is in the closed position.

[0031] The storage mechanism 10 includes a fixed plate 101, a connecting rod 102 and a storage frame 103. The surface of the fixed plate 101 is fixedly connected to the surface of the pull plate 8. There are two connecting rods 102 and two storage frames 103. The two connecting rods 102 are fixedly connected to the surface of the fixed plate 101 respectively, and the storage frame 103 is fixedly connected to the surface of the connecting rods 102. The surface of the storage frame 103 contacts the inner wall of the limit frame 2, and the dustproof screen plate 11 contacts the inner wall of the storage frame 103. The dustproof screen plate 11 can be stored by the setting of the storage frame 103. When the staff needs to disassemble the mounting frame 5 and pull the pull plate 8, the fixed plate 101 drives the storage frame 103 to move through the connecting rod 102. At this time, the dustproof screen plate 11 is moved out of the inside of the limit frame 2 along with the storage frame 103. Based on this, the staff can clean or replace the dustproof screen plate 11 to ensure the use effect of the dustproof screen plate 11.

[0032] The auxiliary mechanism 15 includes a hollow ring 151, clamping plates 152 and arc-shaped grooves 153. The surface of the hollow ring 151 is in contact with the inner wall of the cylindrical groove. The number of the clamping plates 152 is two, and the two clamping plates 152 are respectively fixedly connected to both sides of the surface of the hollow ring 151. The surface of the clamping plate 152 is in contact with the inner wall of the card slot 12. The surface of the flap 14 is in contact with the surface of the clamping plate 152. The arc-shaped groove 153 is formed in the surface of the hollow ring 151, and the inner wall of the arc-shaped groove 153 is in contact with the surface of the extension rod 16. Since part of the dust will be blown towards the inner wall of the hollow ring 151 when the cooling fan 17 rotates, therefore, after the staff rotates the flap 14, the hollow ring 151 can be extracted from the inside of the cylindrical groove. Accordingly, the staff can clean the inner wall of the hollow ring 151. After that, when the staff places the hollow ring 151 inside the cylindrical groove, the surface of the arc-shaped groove 153 is in contact with the surface of the extension rod 16, and the surface of the clamping plate 152 fits with the inner wall of the card slot 12. After that, when the staff rotates the flap 14, the position of the clamping plate 152 can be restricted, so as to fix the position of the hollow ring 151.

[0033] The ejection mechanism 18 includes an ejection plate 181, a second compression spring 182 and an L-shaped plate 183. The surface of the ejection plate 181 is slidably connected to the inner wall of the storage groove. The second compression spring 182 is arranged inside the storage groove, and both ends of the second compression spring 182 are fixedly connected to the bottom of the inner wall of the storage groove and the bottom of the ejection plate 181 respectively. The L-shaped plate 183 is fixedly connected to the bottom of the ejection plate 181, and the surface of the L-shaped plate 183 is slidably matched with the inner wall of the rectangular groove. Through the cooperation of the ejection plate 181 and the second compression spring 182, the mounting bracket 5 can be ejected. In addition, the L-shaped plate 183 can limit the movable range of the ejection plate 181.

[0034] Working principle: When it is necessary to disassemble and clean the mounting bracket 5, the staff can first pull the pull plate 8. At this time, the U-shaped rod 72 drives the positioning block 71 to move, and the limit on the short column 6 is released. The second compression spring 182 and the ejection plate 181 cooperate to eject the mounting bracket 5. Accordingly, the staff can disassemble the mounting bracket 5. At the same time, when the staff pulls the pull plate 8, the fixed disk 101 drives the storage frame 103 to move out of the inside of the limit frame 2 through the connecting rod 102. After that, the staff can pull out the dust-proof net plate 11 and clean or replace the dust-proof net plate 11;

[0035] When the staff takes out the mounting bracket 5, tools such as a soft brush can be used to clean the dust on the surface of the cooling fan 17. In addition, when cleaning the mounting bracket 5, the staff can first rotate the flap 14 to release the limit of the flap 14 on the clamping plate 152. Accordingly, the staff can pull out the hollow ring 151 and clean its inner wall.
