Description

Technical Field

[0001] The utility model relates to the field of cooling devices, in particular to a computer embedded CPU cooling device. Background Technique

[0002] The computer embedded CPU is the core component of the embedded system. It is responsible for controlling and assisting the operation of the system. The embedded CPU is a type of CPU, and a large amount of heat will also be generated during installation and use. In order to ensure the safe use of the embedded CPU, heat dissipation of the embedded CPU is required, so a cooling device needs to be used.

[0003] The cooling device usually consists of a heat conduction base, heat dissipation fins and a fan. The heat conduction base is placed on the embedded CPU and fixed by a buckle. After connecting the fan to the power supply, it can be used. However, in the existing COU cooling device, the entire device is installed and connected by a clamping method. Since the position of the buckle and the device is fixed, when the clamping connection is made, it is very easy to occur that the heat conduction base does not contact the surface of the embedded CPU, which will affect the normal heat transfer effect, resulting in poor heat dissipation of the embedded CPU and easy damage after long-term high-temperature use. And using the clamping method for installation, if the clamped part is damaged, it cannot be effectively connected, which will affect the installation stability of the entire device. In the cooling device, a protective frame is usually set on the fan. The protective frame and the fan are installed by the same set of screws. When the fan blades become dirty, after removing the protective frame, the fan is also removed from the heat dissipation fins. When installing again, it will affect the accuracy, and using screws to install the protective frame is not convenient for replacing the protective frame. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a computer embedded CPU cooling device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

Specific implementation manner

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0019] As Figures 1 - 4 shown, a computer embedded CPU cooling device includes a heat conduction base 1, a heat sink 2 is provided on the heat conduction base 1, a fan housing 3 is provided on the heat sink 2, a mounting structure 7 is provided on the heat conduction base 1, a protection structure 8 is provided on the fan housing 3, the heat conduction base 1 and the heat sink 2 are integrally formed, a connection groove 6 is opened on the heat sink 2, a counterbore 4 is opened on the fan housing 3, and a mounting bolt 5 is provided in the counterbore 4, the lower end of the mounting bolt 5 is arranged in the connection groove 6 on the heat sink 2, the protection structure 8 is installed on the fan housing 3 through the counterbore 4, and a fan blade 9 is arranged inside the fan housing 3. The protection structure 8 includes an annular protection rod 801, a mounting rod 802, a rubber plug 803 and a round plate 804. The annular protection rod 801 is fixedly connected to the mounting rod 802, the rubber plug 803 is arranged at the lower end of the mounting rod 802, and the rubber plug 803 is clamped in the counterbore 4. The round plate 804 is fixed to the upper end of the mounting rod 802. The protection structure 8 is installed on the fan housing 3 in a clamping manner, which is convenient for installation and disassembly. After disassembly, the fan blade 9 can be quickly cleaned, and the operation is more flexible and convenient.

[0020] When installing the cooling device, first use the installation structure 7 to install the heat conduction base 1 onto the embedded CPU, ensuring that the heat conduction base 1 is in close contact with the surface of the CPU. Set the installation bolt 5 in the counterbore 4 so that the lower end of the installation bolt 5 is connected to the connection groove 6, thereby completing the fixation of the fan housing 3 through the installation bolt 5. Install the protection structure 8 on the fan housing 3. During installation, directly insert the rubber plug 803 at the lower end of the installation rod 802 into the counterbore 4 so that the annular protection rod 801 is located above the fan blade 9. After the cooling device is installed, connect the power supply and start using it. During use, the heat generated by the CPU is transferred to the heat sink 2 through the heat conduction base 1, and the rotation of the fan blade 9 in the fan housing 3 drives the hot air to dissipate, which can improve the heat dissipation effect at the heat sink 2. During use, the protection structure 8 plays a role in protecting the fan blade 9. If it is necessary to wipe the fan blade 9, directly lift the installation rod 802 through the round plate 804 so that the rubber plug 803 is pulled out of the counterbore 4, and then wipe the fan blade 9. After wiping, reinstall the protection structure 8.

[0021] Through the above implementation, the installation structure 7 includes a connecting plate 701, a connecting rod 702, a mounting bracket 704 and a bottom plate 705. The connecting plate 701 is fixedly connected to the connecting rod 702, and the connecting plate 701 is arranged on the heat conducting base 1. The mounting bracket 704 and the bottom plate 705 are fixedly connected, and the mounting bracket 704 is sleeved on the connecting rod 702. The installation structure 7 further includes a limit end 703, a waist-shaped hole 706, a strip-shaped hole 707, a lifting limit plate 708, a connecting plug 709, a stud 710, a nut 711 and a pressing spring 712. The limit end 703 is threadedly connected to the upper end of the connecting rod 702. The waist-shaped hole 706 is opened on the bottom plate 705. The strip-shaped hole 707 is opened on the limit end 703. The lifting limit plate 708 is sleeved on the connecting rod 702. The connecting plug 709 is fixed together with the stud 710, and the connecting plug 709 is connected to the lifting limit plate 708. The connecting plug 709 is located in the strip-shaped hole 707. The nut 711 is connected to the stud 710. The pressing spring 712 is sleeved on the connecting rod 702, and the end portions of the pressing spring 712 respectively contact the connecting plate 701 and the lifting limit plate 708. Through the set installation structure 7, the waist-shaped hole 706 is provided on the bottom plate 705, and the mounting bracket 704 is rotatably connected to the connecting rod 702. During the installation process, rotational fine adjustment can be performed, improving the installation flexibility and adaptability. The lifting limit plate 708 is provided on the connecting rod 702 and used in cooperation with the pressing spring 712. Using the elastic pressing effect, the heat conducting base 1 is in close contact with the surface of the embedded CPU, which can ensure the subsequent heat conduction effect and ensure that the heat generated by the embedded CPU can be quickly dissipated. The connecting plug 709 and the stud 710 are provided at the end of the lifting limit plate 708, and the nut 711 is provided on the stud 710, which can adjust the height of the lifting limit plate 708, thereby changing the action effect of the pressing spring 712 and having higher use flexibility.

[0022] When installing the heat conduction base 1, place the heat conduction base 1 on the embedded CPU, and move the mounting bracket 704 downward. The mounting bracket 704 and the bottom plate 705 drive the lifting limit plate 708 to descend until the bottom plate 705 contacts the computer motherboard. The lifting limit plate 708 descends along the connecting rod 702 and compresses the abutting spring 712. Pass the screw through the waist-shaped hole 706 and connect it to the computer motherboard to fix the bottom plate 705 and the mounting bracket 704. During this process, the mounting bracket 704 can rotate on the connecting rod 702 and cooperate with the waist-shaped hole 706 to ensure the installation adaptability. After the mounting bracket 704 is fixed, under the action of all the mounting brackets 704 and the connecting rods 702, the position of the connecting plate 701 is relatively fixed. At the same time, due to the abutting action of the abutting spring 712, the connecting plate 701 exerts a downward acting force on the heat conduction base 1, making the heat conduction base 1 closely contact the embedded CPU, thereby ensuring the heat transfer to the embedded CPU. When needed, the nut 711 on the stud 710 can be loosened, so that the lifting limit plate 708 moves along the connecting rod 702, and the connecting plug 709 moves in the strip-shaped hole 707, thereby changing the compression state of the abutting spring 712, and further being able to change the elastic acting force on the connecting plate 701. After the adjustment is completed, it can be locked and fixed by using the nut 711. The structure is simple, the operation is highly convenient, and the use effect is good.
