Description

Technical Field

[0001] This utility model relates to the field of graphics card fan technology, and in particular to a graphics card fan with cooling function. Background Technology

[0002] In the field of graphics card cooling technology, air cooling has become the mainstream solution due to its advantages such as simple structure and low cost. Existing graphics card cooling systems are usually equipped with axial or centrifugal fans, which force the airflow direction to be changed by the rotation of the blades, so as to quickly remove the heat generated by heat-generating components such as graphics card core and memory, and increase the heat exchange area by using heat sink fins to improve heat dissipation efficiency.

[0003] However, as graphics card performance continues to improve, its power consumption and heat generation increase significantly, and traditional air cooling is gradually facing bottlenecks: on the one hand, the noise problem caused by the increase in fan speed is becoming more and more prominent. Due to the physical characteristics of air and the design of the air duct, it is difficult to achieve a breakthrough in heat dissipation efficiency by simply increasing the air volume; on the other hand, when the ambient temperature is high or the system is running under high load for a long time, the temperature difference between the airflow and the heat-generating components decreases, resulting in a decrease in heat exchange efficiency and a tendency for performance throttling caused by insufficient heat dissipation.

[0004] Currently, the industry mainly improves air cooling performance by optimizing fan blade design, improving heat sink fin layout, or using heat pipes for heat conduction, but none of these methods fundamentally solve the problem of airflow temperature limitation. Therefore, how to further reduce airflow temperature on the basis of existing air cooling and break through the traditional heat dissipation bottleneck has become a key issue that urgently needs to be addressed in the field of graphics card heat dissipation technology.

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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 As one embodiment of this utility model, a graphics card fan with cooling is disclosed. Specifically, the graphics card fan includes a frame 1 with a central opening. The frame 1 has a supporting part 11 formed inside the opening. Of course, in this embodiment, the opening is used to install the fan assembly 2.

[0027] A fan assembly 2 is installed above the bearing part 11. A cooling component 3 is fixedly installed inside the frame 1 around the opening. In this embodiment, the cooling component 3 is set as a TEC cooling chip, with its cold end facing the side of the fan assembly 2 and its hot end being separated from the frame 1 by a certain space. This space is designed to dissipate heat from the hot end. Preferably, several through holes can also be opened on the outside of the frame 1, with the through holes facing the cooling component 3, so as to quickly dissipate the heat generated by the cooling component 3.

[0028] A temperature measuring component 4 is installed below the support part 11, and the temperature measuring component 4 and the support part 11 are detachably connected by a connecting positioning structure 5.

[0029] Specifically, by installing the cooling component 3 in the frame 1, the airflow at a temperature lower than the ambient temperature can enter the fan assembly 2 to enhance heat dissipation. Under the same conditions, the heat dissipation efficiency of the module can be further improved, thereby achieving higher heat dissipation capacity or reducing the cost of the heat dissipation module. In addition, by using a temperature measuring component 4 to monitor the airflow temperature, the cooling component 3 can be shut off when the predetermined temperature is reached to avoid damage to the cooling component 3 caused by continuous operation. This achieves convenience and reliability in heat dissipation control.

[0030] In some embodiments, the fan assembly 2 of this utility model includes a motor bracket 21, and a fan blade 22 is rotatably connected above the motor bracket 21 via a motor. The motor bracket 21 and the support portion 11 are fixedly connected. That is, in this embodiment, a motor is fixedly installed above the motor bracket 21, and the output end of the motor is fixedly connected to the fan blade 22. Thus, the fan blade 22 can be driven to rotate by the motor. Of course, in this embodiment, the motor bracket 21 can be fixedly installed above the support portion 11 by bolts or other fasteners. In this embodiment, the support portion 11 is set as a U-shaped structure.

[0031] It should be noted that the lower part of the cooling component 3 in this embodiment extends to the lower side of the fan blade 22. In this way, when the fan blade 22 rotates, it will drive the airflow to come into contact with the low temperature, thereby reducing the temperature of the airflow.

[0032] Based on the above embodiments, in this embodiment, air ducts 23 are provided on the opposite surfaces of the motor bracket 21 and the bearing part 11. The two air ducts 23 are arranged opposite each other and connected vertically. The air ducts 23 are located above the temperature measuring component 4. The air ducts 23 can be used to keep the airflow in contact with the temperature measuring component 4 so that the temperature measuring component 4 can detect the incoming airflow.

[0033] Preferably, in this embodiment, a positioning groove 12 and an expansion air duct 23 are also formed above the bearing part 11. The end of the motor bracket 21 is inserted into the positioning groove 12, that is, the positioning groove 12 is used to install and position the motor bracket 21. The expansion air duct 13 is located above the temperature measuring component 4. By using the expansion air duct 13, the area on which the airflow flows into the temperature measuring component 4 can be further increased to ensure the accuracy of the detection.

[0034] In some embodiments, the temperature measuring component 4 in this invention is a temperature sensing chip, which includes a circuit board and a temperature sensor electrically connected to the circuit board. Specifically, refer to the temperature sensor module in the prior art. Its specific structure and principle are prior art and will not be described in detail here. Obviously, the temperature sensor in this embodiment should be facing the air duct 13 to ensure the accuracy of airflow detection.

[0035] A mounting position 14 is provided below the support part 11, and the temperature sensing chip is installed in the mounting position 14. Of course, in this embodiment, when the temperature sensing chip is installed inside the mounting position 14, its lower side is flush with the lower side of the support part 11 to ensure the consistency of appearance.

[0036] Based on the above embodiments, the connection positioning structure 5 in this embodiment includes two notches on both sides below the bearing part 11. The notches are connected to the mounting position 14. A claw 51 is formed in the notch. An avoidance opening 41 is formed on the side of the temperature measuring component 4. The claw end of the claw 51 is engaged with the lower part of the temperature measuring component 4, and its arm is placed in the avoidance opening 41.

[0037] It should be noted that the claw 51 described in this embodiment has an L-shaped structure, which can be divided into an arm and a claw end. In order to achieve the positioning of the temperature measuring component 4, the arm end of the claw 51 is placed into the clearance opening 41, and the claw end is used to engage the bottom of the circuit board. Of course, the clearance opening 41 described in this embodiment is opened on the circuit board.

[0038] Furthermore, in this embodiment, the mounting position 14 is also formed with a positioning post 52, and the end face of the temperature measuring component 4 is provided with a positioning hole 42 that is inserted into the positioning post 52. Through the insertion and cooperation of the positioning post 52 and the positioning hole 42, the positioning accuracy of the entire temperature measuring component 4 can be further improved. Of course, in this embodiment, the positioning hole 42 is also provided on the circuit board. During installation, the temperature measuring component 4 is installed into the mounting position 14 through the cooperation of the positioning post 52 and the positioning hole 42, and then the two claws 51 are used to lock and position the temperature measuring component 4, so as to achieve convenient connection and fixation of the temperature measuring component 4.

[0039] It should be noted that, in this embodiment, the cooling component 3 has an arc-shaped structure and there are two of them, with the two cooling components 3 surrounding the outside of the fan assembly 2.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
