Description

Technical Field

[0001] This utility model belongs to the field of heat sink technology, specifically relating to a computer CPU heat sink. Background Technology

[0002] The Central Processing Unit (CPU), as the core of a computer's computing and control, generates a large amount of Joule heat when operating at high speeds. Accumulated heat can cause a rapid rise in chip temperature, leading to anything from system throttling and stuttering to permanent hardware damage. The core mission of a CPU cooler is to create an efficient heat transfer channel. A thermally conductive base (usually made of copper or aluminum) that fits tightly against the CPU's metal top cover utilizes the excellent thermal conductivity of metal to quickly capture heat from the chip surface. In passive cooling mode, this heat is diffused into the air through natural convection via carefully designed metal fins. A more common approach is active air cooling, which involves installing a cooling fan above the fins. This forced airflow significantly improves air exchange efficiency per unit time, accelerating heat removal from the chassis. For extreme overclocking or high-performance computing scenarios, water cooling systems utilize circulating fluid between the heat absorber and a large radiator, leveraging the higher specific heat capacity of water and the large surface area of ​​the radiator for even more efficient heat exchange. The entire heat dissipation process is essentially a three-step coordinated process of heat conduction, diffusion, and dissipation. Its efficiency directly depends on the overall coordination of the heat conduction medium performance, heat pipe vacuum phase change efficiency, fin surface area, and aerodynamic design, ultimately ensuring that the CPU is always maintained within a safe operating temperature range, providing a solid foundation for stable system operation.

[0003] Existing CPU air coolers consist of multiple metal fins, which are quite sharp and can easily scratch users when installing fans and other components, making them unsafe to use.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a computer CPU heatsink.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a computer CPU heatsink to solve the problem that the heat dissipation structure of existing CPU air coolers is composed of multiple metal fins, which are relatively sharp and can easily scratch users when installing fans and other components, making them unsafe to use.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A computer CPU heatsink, comprising:

[0009] A heat dissipation mechanism includes a mounting bracket and a heat-conducting block fixedly disposed on the upper surface of the mounting bracket. The heat-conducting block is provided with a plurality of heat-conducting copper pipes, and a plurality of heat dissipation fins are fixedly installed on the periphery of the heat-conducting copper pipes.

[0010] The protective mechanism includes an external panel disposed on the heat dissipation fins. The external panel includes a first clamping panel and a second clamping panel. A threaded connecting cylinder is fixedly disposed on one surface of the second clamping panel. The threaded connecting cylinder has a threaded hole. A clamping component is disposed on the first clamping panel.

[0011] Preferably, the clamping assembly includes a telescopic groove formed on one side of the first clamping panel, a telescopic panel and a tension spring are disposed in the telescopic groove, the telescopic panel is slidably engaged with the telescopic groove, and the two ends of the tension spring are fixedly connected to the telescopic groove and the telescopic panel respectively.

[0012] Preferably, one end of the telescopic panel is fixedly connected to a locking protrusion, and the heat dissipation fins are provided with a slot, wherein the locking protrusion and the slot are engaged.

[0013] Preferably, the first clamping panel and the second clamping panel are L-shaped, and a pad is provided at the end of the second clamping panel away from the threaded connecting cylinder, and the pad is in contact with the heat dissipation fins.

Through the sliding cooperation between the telescopic panel and the telescopic groove, the clamping protrusion on the telescopic panel can be installed in the groove, and the second clamping panel can be attached to the other side of the heat dissipation fins. The limiting effect of the clamping protrusion and the pulling effect of the tension spring can fix the entire external panel on the heat dissipation fins. The cooling fan can be installed through the threaded connecting sleeve on the second clamping panel. Compared with the traditional hook-type installation method, this device allows the fan to be installed without the hand directly contacting the heat dissipation fins, thereby reducing the probability of being scratched.

[0018] (2) The present invention can fit the heat sink fins by setting the first clamping panel and the second clamping panel with an L-shaped structure. A pad is set on the inner side of the second clamping panel. The position of the pad corresponds to the threaded connecting cylinder, which can avoid the heat sink fins being compressed when installing the fan screw. At the same time, the device also has a disassembly and assembly slot on the first clamping panel, which can provide a gripping space during disassembly and assembly, and at the same time provide sufficient heat dissipation space for the heat sink fins.
