Description

Technical Field

[0001] This invention relates to the field of heat dissipation in electronic devices, and more particularly to centrifugal heat sinks. Background Technology

[0002] In the field of electronic device heat dissipation, centrifugal heat sinks are widely used due to their advantages such as high efficiency and compact structure. When a traditional centrifugal heat sink is working, a centrifugal cooling fan drives outside air axially into the system. Utilizing the centrifugal effect generated by the rotating fan blades, the air is flung out circumferentially, forming a vortex-like diffused airflow around the fan blades. Several fins are arranged next to the centrifugal cooling fan, each fin positioned parallel to the heat sink plate to form a heat dissipation channel. A front-to-back air intake channel is left between the cooling fan and this arrangement. The centrifugal cooling fan rotates circumferentially and exhausts air centrifugally. Specifically, part of the airflow is blown from the front section of the air intake channel towards the front section of the arrangement, and the other part is blown from the rear section of the air intake channel towards the rear section of the arrangement, carrying away heat.

[0003] As the radiator continues to run, the centrifugal cooling fan blows air tangentially towards the fins at the beginning of the fin arrangement. The dust it carries mainly adheres to and accumulates on the front section of the air intake duct at the beginning of the fin arrangement, which greatly reduces the airflow into the rear section of the air intake duct. This results in a significant decrease in the radiator's heat dissipation efficiency, affecting the normal operation of the equipment and shortening the lifespan of the equipment components. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a centrifugal radiator that can significantly reduce the impact of dust accumulation on air duct blockage on the radiator, thereby improving heat dissipation efficiency and equipment operation reliability.

[0005] To solve the above-mentioned technical problems, the present invention provides a centrifugal radiator with multiple fins arranged in a manner, forming a heat dissipation channel between adjacent fins. The multiple fins form at least two heat dissipation channels, and the fins and the heat dissipation channels between adjacent fins are arranged in a front-to-back manner. A cooling fan is installed on the side of the arrangement formed by the fins and the heat dissipation channels. An air intake channel in the front-to-back direction is left between the cooling fan and the arrangement. The cooling fan rotates circumferentially and blows out air centrifugally. Part of the airflow blown out is blown from the front section of the air intake channel to the rear section of the air intake channel, and the other part is blown directly to the rear section of the air intake channel. The airflow blown to the front section of the air intake channel is partly blown to the front section of the arrangement, and the other part is blown to the rear section of the arrangement via the rear section of the air intake channel. The fins arranged at the rear are farther from the rotation axis of the cooling fan than the fins arranged at the front.

[0006] Furthermore, it includes fin plates, with fins arranged on the fin plates.

[0007] Furthermore, a fan plate is mounted on the fin plate, and the cooling fan is located on the fan plate.

[0008] Furthermore, the fin plate is provided with a power taking part and a power supply part that takes power from the power taking part, and the fan plate is correspondingly provided with a power taking part that connects to the cooling fan. When the fan plate is installed on the fin plate, the power taking part of the fan plate connects to the power supply part of the fin plate to take power for the cooling fan to run.

[0009] Furthermore, the fin plate surface has a first slot near the side plate where the cooling fan is located, and the fin plate surface forms a boss on the front and / or rear sides that is flush with the height of the fin protrusion, with a second slot on the boss; the side plate near the cooling fan of the fan plate is folded towards the fin plate to form a flange, and the end of the flange extends towards the fin plate with a first locking member, and the side plate near the fins of the fan plate extends towards the fin plate with a second locking member; the first locking member and the first slot of the fin plate and the fan plate are engaged with each other, and the second locking member and the second slot are engaged with each other.

[0010] Furthermore, the fin plate has a protruding latching part, which extends towards the flange of the fan plate and has a corresponding latching hole, into which the latch engages.

[0011] Furthermore, the cooling fan is a turbo fan.

[0012] The centrifugal radiator provided by this invention has fins arranged at the rear that are farther from the rotating axis of the cooling fan than fins arranged at the front, resulting in the following beneficial effects:

[0013] (1) The fins gradually move away from the rotating axis of the cooling fan from front to back, which is in line with the centrifugal airflow direction of the circumferential rotation, reducing the impact of the airflow directly impacting the fins and causing rebound that affects the heat dissipation efficiency.

[0014] (2) The rear section of the air intake duct is wide enough that even if dust accumulates and blocks the front section of the duct, the fan will still have enough airflow to blow towards the rear section of the air intake duct to cool the fins.

[0015] (3) The two adjacent fins serve as the front and rear walls of the heat dissipation air duct. The beginning of the rear wall is far from the beginning of the front wall, so it is not easy to be completely blocked. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to specific embodiments.

[0026] Centrifugal radiators, such as Figure 1 , 2 As shown, it includes a finned plate 1 and a fan plate 2 mounted on the finned plate 1. The front of the finned plate 1 is shown below. Figure 3 As shown, multiple fins 11 are arranged from front to back, with heat dissipation channels formed between adjacent fins 11. The fins 11 and the heat dissipation channels between adjacent fins 11 form a front-to-back arrangement 12. The front of the fin plate 1 has space on the left side of the arrangement 12 to accommodate a turbine fan 21, which serves as a cooling fan. The back of the fan plate 2 is shown... Figure 4 As shown, a fan box 27 is provided on its left side accordingly. The fan box 27 is as follows: Figure 6 As shown, a turbine fan 21 is provided, with its axis of rotation perpendicular to the fan plate 2. Figure 2 As shown, the fan plate 2 can be installed with its back side facing and close to the front side of the fin plate 1, as... Figure 4 As shown, the fan housing 27 has an air outlet 271, and the fan plate 2 is mounted on the fin plate 1 (see...). Figure 6 , Figure 6 (If fan plate 2 is not shown), then the air outlet 271 of the fan box 27 faces the arrangement 12.

[0027] like Figure 3As shown, the left side of the front of the fin plate 1 has two first slots 15, one in front and one behind. Both the front and rear sides of the arrangement 12 have protrusions 19 flush with the height of the fin 11, and second slots 13 are formed on the protrusions 19. (See diagram). Figure 4 As shown, the left edge of the fan plate 2 is folded towards its back to form a flange 29. Two first locking pieces 25 extend from the end of the flange 29, and two second locking pieces 23 extend from the right edge of the fan plate 2 towards the fin plate 1. With the back of the fan plate 2 facing and close to the front of the fin plate 1, the first locking pieces 25 and the first locking slot 15 engage with each other, and the second locking pieces 23 and the second locking slot 13 engage with each other, thus mounting the fan plate 2 onto the fin plate 1. Figure 2 As shown, the fin plate 1 has a latching part 14 protruding from the left side of the front, and the latching part 14 extends to the left with a latch 141; the fan plate 2 is as follows Figure 4 As shown, a corresponding snap-fit ​​hole 24 is provided on its flange 29, and the buckle 141 is snapped into the snap-fit ​​hole 24 to further fix the fan plate 2 and prevent it from coming out in the front direction.

[0028] Fan plate 2 front side as shown Figure 2 As shown, it has an air inlet 22 at the location corresponding to the turbine fan 21, leading to the turbine fan 21. The turbine fan 21 is mounted on the finned plate 1, as shown. Figure 6 As shown (fan plate 2 is not shown in the figure), an air inlet duct 18 is provided between the fan box 27 and the arrangement 12. The turbine fan 21 operates to cause airflow from the air inlet 22 (see Figure 2 Axial air intake and circumferentially clockwise centrifugal air outlet 271 blown into the intake duct 18. Part of the blown airflow travels from the front section 181 to the rear section 182 of the intake duct, while the other part blows directly into the rear section 182. The airflow blowing towards the front section 181 is partly directed towards the front of the 12-arranged array, and partly via the rear section 182. The airflow directly towards the rear section 182 then travels directly to the rear of the 12-arranged array. The blown airflow cools the fins 11 in the 12-arranged array. With the turbine fan 21 running continuously for extended periods, dust carried by its airflow accumulates in the front section 181, clogging the intake duct. This significantly reduces the airflow into the rear section 182, resulting in a substantial decrease in the radiator's cooling efficiency. Therefore, the arrangement of 12 is designed as follows Figure 6 As shown, the fins 11 arranged at the rear are farther from the rotation axis of the turbine fan 21 than the fins 11 arranged at the front, and the arrangement of the fins 12 gradually moves away from the rotation axis of the turbine fan 21 from front to back. This arrangement of the fins 11 conforms to the centrifugal airflow direction of the circumferential rotation, reducing the impact of airflow rebound due to direct impact on the fins 11, which affects heat dissipation efficiency. It also makes the rear section 182 of the air intake duct sufficiently wide to increase the airflow that can directly blow onto this part of the air intake duct 182, even if there is thick dust 3. Figure 7Even though the clumps of fins block the front section 181 of the air intake duct, there is still sufficient airflow to cool the rear section of the fins 11. Furthermore, compared to conventional turbine radiators, in this embodiment, the rear fins 11 are farther from the rotation axis of the turbine fan 21 than the front fins 11. Figure 8 As shown, the distance D between the beginning of the rear wall and the beginning of the front wall is larger than the width d of the heat dissipation duct, making it less likely to be completely blocked.

[0029] Back of fin plate 1 (see) Figure 5 The fin plate connector 17 draws power from the outside to supply power to the front of the fin plate 1 (see...). Figure 3 ) Fin plate socket 16. Fan plate 2 back (see Figure 4 Correspondingly, a fan plate plug 26 for drawing power from the fin plate socket 16 is provided on the side of the fan box 27. The fan plate plug 26 is connected to the turbine fan 21 inside the fan box 27. When the fan plate 2 is installed on the fin plate 1, the fan plate plug 26 connects to the fin plate socket 16 to draw power to the turbine fan 21 for operation.
