Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile heat sinks, and particularly relates to an aluminum profile heat sink with novel staggered fins. Background Technique

[0002] During the use of an aluminum profile heat sink, staggered fins are used to increase the heat dissipation speed of the device. For example, an efficient anti-deformation aluminum profile heat sink with the application number "CN202222159942.7" only increases the heat dissipation effect of the device by increasing the heat dissipation area, resulting in a low cooling rate of the device for gas utilization, which is not conducive to the use of the device. Content of the Utility Model

[0003] The purpose of the utility model is to provide an aluminum profile heat sink with novel staggered fins to solve the problems raised in the above background technique.

[0004] An aluminum profile heat sink with novel staggered fins includes a bottom plate and a heat dissipation plate: a heat sink is arranged at the upper end of the bottom plate, and an air cooling mechanism is arranged at the center of the bottom plate.

[0005] Preferably, the air cooling mechanism includes a motor, a fixed disk and blades. A motor is arranged at the center of the bottom plate, the output end of the motor is connected with the fixed disk, and blades are arranged at equal angles on the outer side of the fixed disk.

[0006] When the device is in use, the motor drives the fixed disk and the blades to rotate to generate an air flow, so that the air flow flows from the outside to the surface of the bottom plate, thereby increasing the heat dissipation speed of the device.

[0007] Preferably, the heat dissipation plate is strip-shaped, the heat dissipation plates are spliced into a rectangle missing one side, and several groups of heat dissipation plates are arranged equidistantly from the outside to the inside on the surface of the bottom plate, and the missing directions of each group of heat dissipation plates are different.

[0008] The heat sink can increase the gas contact area between the device and the outside, thereby increasing the heat dissipation speed of the device.

[0009] Preferably, the longitudinal section of the heat dissipation plate is a trapezoid with a wider upper part and a narrower lower part.

[0010] When the gas contacts the heat dissipation plate, the heat dissipation plate can guide the gas, so that the gas flows downward along the heat dissipation plate, thereby improving the heat dissipation speed of the device.

[0011] Preferably, the missing parts of each group of heat sinks are the left and right sides.

[0012] The missing directions of each group of heat sinks are different, and the left and right sides of the heat sinks are missing. Since the front side of the heat sink is the incoming high-pressure gas, when the gas flows outward along the heat sink, under the guiding action of the heat sink, part of the gas will collide and cancel each other out, thereby reducing the air pressure at the heat sink and facilitating the entry of external gas between the heat sinks.

[0013] Preferably, fixing holes are equidistantly arranged at the upper end inside the heat sink, and the fixing holes are funnel-shaped.

[0014] The diameter of the fixing hole on the side close to the motor is smaller than the diameter of the other side of the fixing hole. That is, when the heat sink guides the gas, causing the impact pressure of the gas to increase, the gas will flow outward through the fixing hole. At this time, the gas will expand, thereby dissipating heat from the gas and reducing the temperature of the gas, further improving the heat dissipation effect of the device.

[0015] Preferably, a heat dissipation plate is arranged at the lower end of the heat sink.

[0016] The heat dissipation plate can increase the overall heat dissipation area of the device, thereby improving the heat dissipation speed.

[0017] Preferably, the heat dissipation plate is in a "V" shape.

[0018] When the gas blows towards the heat dissipation plate, since the heat dissipation plate is in a "V" shape, it can block the gas flow. And since the heat dissipation plate is located below the fixing hole, it will increase the air pressure at the fixing hole, while the other side surfaces of the heat sink are smooth, increasing the gas flow effect.

[0019] The beneficial effects of the present utility model are:

[0020] 1. When the device is in use, the rotation of the blades will be used to accelerate the gas flow speed, and then the heat sink will be used to set a fixed route to increase the utilization rate of the gas. At the same time, the impact of the gas will be used to form a high-pressure gas belt, and then it will be discharged through the fixing hole to dissipate heat from the gas.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0029] During specific implementation: As Figures 1-5 shown, a new type of aluminum profile heat sink with staggered fins includes a bottom plate 1 and a heat dissipation plate 7: a heat sink 5 is arranged at the upper end of the bottom plate 1, and an air cooling mechanism is arranged at the center of the bottom plate 1

[0030] The air cooling mechanism includes a motor 2, a fixing plate 3 and blades 4. A motor 2 is arranged at the center of the bottom plate 1, the output end of the motor 2 is connected to a fixing plate 3, and blades 4 are arranged at equal angles on the outside of the fixing plate 3

[0031] When the device is in use, the motor 2 drives the fixing plate 3 and the blades 4 to rotate to generate air flow, so that the air flow flows from the outside to the surface of the bottom plate 1, thereby increasing the heat dissipation speed of the device

[0032] The heat dissipation plate 7 is strip-shaped, the heat dissipation plates 7 are spliced into a rectangle missing one side, and several groups of heat dissipation plates 7 are arranged equidistantly from the outside to the inside on the surface of the bottom plate 1, and the missing directions of each group of heat dissipation plates 7 are different

[0033] The heat sink 5 can increase the gas contact area between the device and the outside, thereby increasing the heat dissipation speed of the device

[0034] The longitudinal section of the heat dissipation plate 7 is a trapezoid with a wider upper part and a narrower lower part

[0035] When the gas contacts the heat dissipation plate 7, the heat dissipation plate 7 can guide the gas, so that the gas flows downward along the heat dissipation plate 7, thereby improving the heat dissipation speed of the device

[0036] Each group of heat sinks 5 is missing on the left and right sides

[0037] The missing directions of each group of heat sinks 5 are different, and the left and right sides of the heat sinks 5 are missing. Since the front side of the heat sinks 5 is the incoming high-pressure gas, when the gas flows outward along the heat sinks 5, under the guiding action of the heat sinks 5, part of the gas will collide and cancel each other, thereby reducing the air pressure at the heat sinks 5 and facilitating the entry of external gas between the heat sinks 5.

[0038] Fixing holes 6 are equidistantly arranged at the upper end inside the heat sinks 5, and the fixing holes 6 are funnel-shaped.

[0039] The diameter of the fixing hole 6 on the side close to the motor 2 is smaller than the diameter of the other side of the fixing hole 6. That is, when the heat sinks 5 guide the gas, causing the air pressure of the gas impact to increase, the gas will flow outward through the fixing hole 6. At this time, the gas will expand, thereby dissipating heat from the gas and reducing the temperature of the gas, further improving the heat dissipation effect of the device.

[0040] A heat dissipation plate 7 is arranged at the lower end of the heat sink 5.

[0041] Through the heat dissipation plate 7, the overall heat dissipation area of the device can be increased, thereby improving the heat dissipation speed.

[0042] The heat dissipation plate 7 is in a "V" shape.

[0043] When the gas blows towards the heat dissipation plate 7, since the heat dissipation plate 7 is in a "V" shape, it can block the gas flow. And since the heat dissipation plate 7 is located below the fixing hole 6, it will increase the air pressure at the fixing hole 6, while the other side surfaces of the heat sinks 5 are smooth, increasing the gas flow effect.
