Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, specifically a CPU cooling fan. Background Technology

[0002] With the continuous development of computer technology, CPU performance has become increasingly powerful, integration has become higher, and core frequency has continued to increase. This has led to an increase in the amount of heat generated by the CPU during operation. If this heat cannot be dissipated in a timely and effective manner, the CPU temperature will become too high, resulting in performance degradation, system instability, or even hardware damage. Therefore, the heat dissipation system is crucial to ensuring the normal operation of the CPU, and the CPU cooling fan is one of the most commonly used heat dissipation devices.

[0003] The fan motor technology has also been improved, adopting a more efficient DC motor that can provide higher speed and stability at lower power consumption. Although cooling fans are constantly being improved, their heat dissipation efficiency may still be insufficient in some high-performance computer operating environments. For example, when the CPU is performing high-intensity operations, such as running large games, performing professional graphics rendering or scientific calculations, the fan may not be able to dissipate all the heat generated in time, resulting in excessive CPU temperature, frequency reduction, and affecting computer performance.

[0004] Traditionally, copper pipes in cooling fans are placed vertically within the fins, resulting in obstruction between the pipes and overlapping projections of the areas in contact with the fins on the vertical plane. There is a lack of other effective copper pipe component shapes and installation methods. In view of this, we propose a CPU cooling fan. Utility Model Content

[0005] The purpose of this invention is to provide a CPU cooling fan to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A CPU cooling fan includes a base, which is fixedly mounted to a CPU body by a fastener. A frame is fixedly mounted on the top of the base, and the frame is provided in two sets. A heat dissipation assembly is disposed on the base, and the heat dissipation assembly includes:

[0008] A first axial flow fan is fixedly installed on the outer wall of one set of the frame, and a second axial flow fan is fixedly installed on the outer wall of the other set of the frame. The air inlet and outlet directions of the first axial flow fan and the second axial flow fan are opposite.

[0009] A copper plate is fixedly installed on the inner wall of the center of the base, and the outer wall of the copper plate is attached to the CPU body. An arc-shaped groove is opened at the center of the top of the base, and multiple sets of arc-shaped grooves are provided.

[0010] The U-shaped copper tube has its bottom end snapped into the arc-shaped groove. The U-shaped copper tube is closely attached to the top of the copper plate. Multiple sets of U-shaped copper tubes are provided, and the height of the multiple sets of U-shaped copper tubes decreases sequentially along the direction from the first axial flow fan to the second axial flow fan. The U-shaped copper tubes closer to the first axial flow fan are vertical, while the U-shaped copper tubes farther away from the first axial flow fan are inclined. Fins are snapped into the frame, and the arc-shaped outer wall of the U-shaped copper tube is attached to the inside of the fins.

[0011] Preferably, multiple sets of fasteners are provided, and the multiple sets of fasteners are located at the four corners of the base, so that the fan body is fixed more stably.

[0012] Preferably, the fins are provided in multiple sets, and the multiple sets of fins are arranged in a linear array with equal spacing, thereby improving the heat dissipation effect.

[0013] Preferably, an auxiliary component is provided on the outside of the copper plate. The auxiliary component includes an auxiliary copper block, which is fixedly installed on the CPU body by fasteners. The bottom end of the auxiliary copper block is close to the CPU body. One end of the bent copper tube is fixedly installed on the auxiliary copper block, and a vertical copper tube is fixedly installed on the other end of the bent copper tube.

[0014] Preferably, the frame has a through slot, the vertical copper tube passes through the through slot, and a spiral copper strip is fixedly installed at the other end of the vertical copper tube.

[0015] Preferably, the spiral copper strips are in the form of equally spaced spiral rings, and the outer wall of the spiral copper strips is attached to the inside of the fins, thereby accelerating heat dissipation and improving the heat dissipation effect.

[0016] Compared with the prior art, the present invention provides a CPU cooling fan with the following advantages:

[0017] 1. This CPU cooling fan, in order to better dissipate heat from the CPU, is equipped with a heat dissipation component. First, when the CPU is working, the heat from the CPU is transferred through a copper plate, which then transfers the heat to multiple sets of U-shaped copper pipes, and finally to multiple sets of fins. At the same time, the first and second axial flow fans are activated. Through the rotation of the fan blades inside the first and second axial flow fans, the flowing air continuously carries away the heat from the fins and dissipates it into the surrounding air, thereby achieving the cooling and heat dissipation of the CPU.

[0018] 2. To improve heat dissipation, this CPU cooling fan incorporates auxiliary components. When these components are in operation, the heat from the CPU is conducted through the auxiliary copper block to the bent copper pipe, and then through the vertical copper pipe to the spiral copper strip. The spiral structure of the spiral copper strip further accelerates the heat transfer to the fins, thereby speeding up the removal of heat from the fins and achieving cooling of the CPU.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0028] A CPU cooling fan includes a base 1, which is fixedly mounted on the CPU body by fasteners 2. In addition, there are four sets of fasteners 2, which are located at the four corners of the base 1, so that the fan body is fixed more stably. A frame 3 is fixedly mounted on the top of the base 1, and the frame 3 has two sets.

[0029] In one embodiment of this utility model, a heat dissipation assembly 4 is provided on the base 1. The heat dissipation assembly 4 includes a first axial flow fan 41. The first axial flow fan 41 is fixedly installed on the outer wall of one set of frames 3, and a second axial flow fan 42 is fixedly installed on the outer wall of another set of frames 3. The air inlet and outlet directions of the first axial flow fan 41 and the second axial flow fan 42 are opposite. A copper plate 43 is fixedly installed on the inner wall of the center of the base 1. The outer wall of the copper plate 43 is in contact with the CPU body. An arc-shaped groove 44 is opened at the center of the top of the base 1. Three sets of arc-shaped grooves 44 are provided. U-shaped copper tubes 45 are snapped into the inside of the arc-shaped grooves 44. At the bottom, the U-shaped copper tube 45 is attached to the top of the copper plate 43. There are three sets of U-shaped copper tubes 45, and the height of the three sets of U-shaped copper tubes 45 decreases sequentially along the direction from the first axial flow fan 41 to the second axial flow fan 42. The set of U-shaped copper tubes 45 closer to the first axial flow fan 41 is vertical, and the two sets of U-shaped copper tubes 45 farther away from the first axial flow fan 41 are inclined. Fins 46 are snapped into the frame 3. The arc-shaped outer wall of the U-shaped copper tube 45 is attached to the inside of the fins 46. In addition, there are multiple sets of fins 46, and the multiple sets of fins 46 are linearly arrayed with equal spacing, thereby improving the heat dissipation effect.

[0030] In this embodiment, when the CPU is in operation, its internal electronic components continuously generate a large amount of heat. This heat is rapidly conducted to the surrounding area. The copper plate 43, which is tightly attached to the CPU, captures and transfers the heat due to its excellent thermal conductivity. Since the copper plate 43 is tightly connected to multiple sets of U-shaped copper tubes 45, the heat is continuously conducted to the multiple sets of U-shaped copper tubes 45 along this connection path. The U-shaped copper tubes 45 are usually made of copper, which has excellent thermal conductivity and can quickly transfer heat to various parts. After the heat is conducted to the U-shaped copper tubes 45, the U-shaped copper tubes 45 will evenly distribute the heat to the multiple sets of fins 46 attached to them. The fins 46 have a large surface area, providing ample space for heat dissipation. At the same time, the first Axial flow fan 41 and second axial flow fan 42 start synchronously. The blades inside the first axial flow fan 41 rotate at high speed, and the blades push the air to form a strong negative pressure zone inside the first axial flow fan 41. Under the action of the air pressure difference, the outside air is quickly drawn in and blown towards the fins 46. This fresh air comes into full contact with the heat-carrying fins 46 and absorbs the heat on the fins 46 quickly through heat exchange. The blades of the second axial flow fan 42 also rotate at high speed, but its working direction is opposite to that of the first axial flow fan 41. It draws the hot air that has increased in temperature after heat exchange out of the fin area from the frame 3. In this way, the continuously flowing air carries away the heat on the fins 46 and dissipates it into the surrounding air, thereby effectively cooling the CPU body.

[0031] In one embodiment of this utility model, an auxiliary component 5 is provided on the outside of the copper plate 43. The auxiliary component 5 includes an auxiliary copper block 51, which is fixedly installed on the CPU body by fasteners 52. Two sets of fasteners 52 are provided. The bottom end of the auxiliary copper block 51 is close to the CPU body. One end of the bent copper tube 53 is fixedly installed on the auxiliary copper block 51, and the other end of the bent copper tube 53 is fixedly installed with a vertical copper tube 54. In addition, a through slot 55 is opened on the frame 3, and the vertical copper tube 54 passes through the through slot 55. The other end of the vertical copper tube 54 is fixedly installed with a spiral copper strip 56. In addition, the spiral copper strip 56 is in the shape of an evenly spaced spiral ring. The outer wall of the spiral copper strip 56 is attached to the inside of the fin 46, thereby accelerating the dissipation of heat and making the heat dissipation effect better.

[0032] In this embodiment, when the heat dissipation component 4 starts working, the heat generated by the CPU body has another heat dissipation path. The auxiliary copper block 51 is in direct contact with the CPU body. With its good thermal conductivity, it can absorb some of the heat from the CPU body in time. The auxiliary copper block 51 is firmly fixed to the CPU body by the fastener 52 to ensure the stability of heat transfer. The absorbed heat will be transferred along the auxiliary copper block 51 to the bent copper pipe 53 connected to it. The bent copper pipe 53 then transfers the heat to the vertical copper pipe 54. The vertical copper pipe 54 passes through the through slot 55 on the frame 3 and conducts the heat to the spiral copper strip 56. The spiral copper strip 56 has an evenly spaced spiral ring structure. This special structure greatly increases the surface area, allowing heat to be exchanged with the surrounding environment more quickly. The spiral copper strip 56 further conducts the heat to the fins 46 that are attached to it, accelerating the dissipation of heat on the fins 46, thereby achieving a better cooling effect for the CPU body.

[0033] All electrical components appearing in this application are electrically connected to the controller and power supply on the equipment to be installed. The controller is a conventional and known device that can control the first axial flow fan 41 and the second axial flow fan 42.

The machinery, parts and equipment are all conventional models in the prior art.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
