Description

Technical Field

[0001] This utility model relates to a heat sink for electronic components, specifically a CPU heat dissipation structure. Background Technology

[0002] A CPU cooling structure is a heat dissipation device specifically designed for a computer's central processing unit (CPU). Its main function is to dissipate the heat generated by the CPU during operation in a timely manner to prevent the CPU from being damaged due to overheating.

[0003] The heat pipes in existing CPU cooling structures are usually U-shaped. The center of the heat pipe is in direct contact with the CPU top cover and absorbs heat. The heat is dispersed through the two ends of the heat pipe. However, all the heat absorbed by the heat pipe is dispersed on a set of fins at the same time, resulting in too much heat accumulating on the fins. Therefore, it is not conducive to rapid cooling, which limits the heat dissipation capacity of the cooling structure and leads to poor heat dissipation effect. Utility Model Content

[0004] The purpose of this invention is to provide a CPU heat dissipation structure that allows the heat absorbed by the center of each heat pipe to be dispersed and dissipated by different fans. This facilitates the rapid cooling of each heat pipe, enabling it to absorb heat more efficiently from the CPU top cover surface and improve heat dissipation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CPU heat dissipation structure, including a mounting bracket and heat-conducting and convection components disposed on the mounting bracket. The mounting bracket includes two symmetrically distributed fixing seats, each fixing seat having two second fixing members, and each fixing seat having two first fixing holes, each first fixing hole having a first fixing member. In actual design, a total of four second fixing members are provided. The bottom of the second fixing members is fixed to a matching backplate, which is disposed on the back of the motherboard. The heat dissipation structure is disposed on the front of the motherboard. By installing the four second fixing members into the four screw holes on the backplate, the backplate can support the heat dissipation structure. The mechanism enables heat dissipation from the heat conduction and convection components. The heat conduction component includes a heat conduction base and heat pipes fixed on the heat conduction base. The heat pipes include a heat absorption part and heat distribution parts respectively disposed at both ends of the heat absorption part. Each heat distribution part is provided with a heat dissipation part, which is C-shaped. Multiple heat conduction components are provided, and the heat absorption parts of multiple heat conduction components are arranged side by side. The convection component includes multiple fins and a fan disposed inside the multiple fins. The multiple fins are distributed in the circumferential direction of the fan, and each of the multiple fins is provided with heat pipe perforations. Multiple heat pipes are respectively installed in the multiple heat pipe perforations, so that the heat of the heat pipes can be distributed on multiple fins and blown away by the operation of the fan.

[0006] Preferably, each fixing piece is provided with two second fixing holes, and a total of four second fixing holes are provided, with the four second fixing members respectively installed in the four second fixing holes.

[0007] Preferably, two E-rings are provided on the lower end face of the fixing plate, and two washers are provided on the upper end face of the fixing plate, with each second fixing member passing through an E-ring and a washer.

[0008] Preferably, each of the second fixing members is fitted with a spring on its outer side, and the two ends of the spring abut against the fixing plate and the second fixing member, respectively.

[0009] Preferably, four third fixing holes are provided on the heat-conducting base, and four first fixing holes and four first fixing members are provided. The four first fixing holes are respectively provided below the four third fixing holes.

[0010] Preferably, a heat pipe positioning groove is provided on the heat-conducting base, and the heat-absorbing part is fixed in the heat pipe positioning groove.

[0011] Preferably, a front fixing plate, an inner fixing plate, and a rear fixing plate are fixed on multiple fins, and both the fins and the front fixing plate are L-shaped.

[0012] Preferably, there are two sets of convection components, which are parallel to each other and the fans on the two sets of convection components have the same airflow direction.

[0013] Preferably, each set of convection components has multiple heat pipe perforations on its fins, and multiple heat dissipation parts are fixed in the multiple heat pipe perforations. The multiple heat dissipation parts are in two sets and are respectively set on the two sets of convection components, so that the heat can be evenly distributed on the fins of the two sets of convection components.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting multiple heat pipes to simultaneously absorb heat from the surface of the CPU top cover, and dividing each heat pipe into two parts (two heat dissipation parts), with each part of the heat pipe installed on two sets of convection components respectively, allows the heat absorbed by the central part of each heat pipe to be dispersed and dissipated by different fans. Therefore, it is beneficial to cool down each heat pipe quickly, so that the heat pipe can absorb heat from the surface of the CPU top cover more efficiently and improve the heat dissipation efficiency.
