Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and more specifically, to a spiral flow-guiding cold-forged radiator. Background Technology

[0002] A radiator is a device or instrument that transfers heat generated by machinery or other equipment during operation to prevent it from affecting their normal operation.

[0003] The spiral-guided cold-forged heatsink is a heat dissipation device that combines cold forging technology and a spiral flow-guided structure. It boasts advantages such as high-efficiency heat conduction and compact structure, but also has some inherent drawbacks. The spiral flow-guided structure typically features dense fins and narrow flow channels. While this type of flow channel can achieve efficient heat dissipation under constant temperature conditions, when the heat source power suddenly increases (such as motor overload or chip full-load operation), the airflow within the spiral flow channel struggles to respond quickly by changing its velocity or disturbance intensity, easily leading to heat accumulation. Therefore, we propose a spiral-guided cold-forged heatsink. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a spiral flow-guided cold forging radiator to solve the technical problem that the current spiral flow-guided cold forging radiator cannot dissipate the high cavity temperature in time.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a spiral flow-guiding cold forging radiator, including an outer sleeve, a base plate connected to the bottom of the outer sleeve, several oblique copper tubes laid on the outer wall of the outer sleeve, several inclined slots opened on the outer sleeve, multiple heat dissipation holes opened on the base plate, a flow guide installed in the middle of the base plate, and a spiral flow-guiding structure installed on the inner side of the outer sleeve outside the flow guide;

[0006] The flow guide consists of a flow guide tube, a diffuser plate, and a collecting plate. The diffuser plate is located at the bottom of the flow guide tube and connected to the bottom plate. The collecting plate is located at the top of the flow guide tube. The diffuser plate and the collecting plate are installed in a trapezoidal shape relative to the flow guide tube.

[0007] The spiral flow guiding structure consists of several relatively horizontal layered heat sinks, each layered heat sink consisting of several flow guiding fins. There is a gap between two adjacent flow guiding fins. A flow guiding plate is installed at the high end of each flow guiding fin, and a micro-motion plate is installed on the flow guiding fin.

[0008] Preferably, the outer wall of the guide fin is fixedly connected to the inside of the outer sleeve, the side of the guide fin away from the outer sleeve is attached to the outer wall of the guide tube, the guide fin is spirally arranged along the long axis, and the spiral of the guide fin is one-quarter of the complete spiral, and the clockwise direction between two adjacent guide fins forms an air duct with an increasing diameter.

[0009] Preferably, a sloping groove is formed at the top center of the collecting plate, a motor is installed in the sloping groove, and the output end of the motor is connected to a guide fan blade.

[0010] Preferably, a sleeve is installed at the top of the outer sleeve, and an annular grille is installed on the inner side of the top of the sleeve, with the bottom of the annular grille corresponding to the guide fan blades.

[0011] Preferably, the interior of the guide plate is hollow, and one side of the guide plate is inclined in the same direction as the inclination of the guide fins.

[0012] Preferably, the heat dissipation holes on the base plate are evenly distributed in a gourd shape, and the bottom of the diffuser plate corresponding to the base plate position is a solid structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs a spiral airflow structure. Through the quarter-spiral structure of the airflow fins installed inside, the diameter of the air duct changes from small to large. During use, the air spirals upward through the airflow fins. When the internal temperature is high, the heat radiation causes the pressure to increase. Combined with the external airflow fan blades, the internal air pressure is increased, causing the micro-motion plate to open. The air enters the upper layer through the micro-motion plate, realizing the rapid flow of air and thus preventing heat accumulation. The annular structure can achieve the purpose of spiral airflow.

[0015] 2. This utility model also designs a flow guide structure, which controls the diffusion at the bottom and collects the air at the top through the diffusion plate and the collection plate on the flow guide. This makes the flow guide fins on the periphery of the bottom air diffusion reach the top and then the air is gathered by the collection plate. At the same time, the air is in a negative pressure state when it is in the spiral flow guide structure position, which improves the air flow performance. Attached Figure Description

Detailed Implementation

[0023] like Figures 1 to 6 As shown, this utility model relates to a spiral flow-guiding cold-forged radiator, including an outer sleeve 100, a base plate 110 connected to the bottom of the outer sleeve 100, several oblique copper tubes 130 laid on the outer wall of the outer sleeve 100, several inclined slots 140 opened on the outer sleeve 100, multiple heat dissipation holes 120 opened on the base plate 110, a flow guide installed at the middle position of the base plate 110, and a spiral flow-guiding structure installed on the inner side of the outer sleeve 100 outside the flow guide; the outer sleeve 100 and the base plate... The 110 sections are integrally cold-forged, resulting in a precise structure with higher accuracy compared to extrusion processes. This effectively improves heat dissipation performance. Several copper tubes 130 are evenly installed on the outer wall of the outer sleeve 100 in an inclined manner, which can achieve the purpose of auxiliary heat dissipation of the entire outer sleeve 100. In conjunction with the slots 140 opened on the outer sleeve 100, external air enters the cavity and mixes with the guide fins 400. The slots 140 are opened at an upward angle to ensure that the air entering the cavity is in an upward state, which plays the role of intake auxiliary heat dissipation.

[0024] The flow guide consists of a flow guide pipe 300, a diffuser plate 310, and a collection plate 320. The diffuser plate 310 is located at the bottom of the flow guide pipe 300 and connected to the base plate 110. The collection plate 320 is located at the top of the flow guide pipe 300. The diffuser plate 310 and the collection plate 320 are installed in a trapezoidal shape relative to the flow guide pipe 300. The interior of the flow guide pipe 300 is hollow and is integrally formed with the diffuser plate 310 and the collection plate 320. The diffuser plate 310 and the collection plate 320 have a trapezoidal structure. The diffuser plate 310 can effectively increase the air diffusion flow speed at the bottom, quickly diffuse the air at the bottom to the spiral flow guide structure position, and make it flow quickly. After passing through the flow guide fins 400 at the position of the flow guide pipe 300, the rising air is quickly discharged through the collection plate 320 at the top.

[0025] The spiral airflow guiding structure consists of several horizontally layered heat sinks, each composed of several airflow guiding fins 400. A gap is left between adjacent airflow guiding fins 400. An airflow guiding plate 410 is installed at the upper end of each airflow guiding fin 400, and a micro-motion plate 420 is mounted on each airflow guiding fin 400. The airflow guiding fins 400 have grooves for mounting the micro-motion plate 420. The two sides of the micro-motion plate 420 are connected to the airflow guiding fins 400 by a shaft, and the middle is connected via a switch spring. The bottom of the micro-motion plate 420 has an inclined baffle plate to withstand pressure. The switch spring has a low starting pressure, making it easy for air pressure to open the micro-motion plate 420. When the air pressure is low, the switch spring cannot be activated to return to its original position, thereby increasing the ventilation area.

[0026] This invention utilizes a spiral airflow structure with inclined internal airflow guide fins 400. During operation, air spirals upward through these fins, and in cases of high internal temperature, thermal radiation increases pressure. This, combined with the rotation of the airflow guide fan blades 340, opens the micro-adjustment plate 420, allowing air to flow through and reach the upper layer, thus preventing heat buildup.

[0027] This utility model also designs a flow guide structure, which controls the diffusion at the bottom and collects the air at the top between the diffuser plate 310 and the collection plate 320 on the flow guide. This allows the air to be gathered at the top by the collection plate 320 after reaching the outer periphery of the bottom air diffusion at the flow guide fin 400 position. At the same time, the air is in a negative pressure state when it is in the spiral flow guide structure position, which improves the air flow performance.

[0028] Specifically, the outer wall of the guide fin 400 is fixedly connected to the interior of the outer sleeve 100. The side of the guide fin 400 away from the outer sleeve 100 is attached to the outer wall of the guide pipe 300. The guide fin 400 is spirally arranged along its long axis, and the spiral of the guide fin 400 is one-quarter of a complete spiral. The clockwise direction between two adjacent guide fins 400 forms an air duct with an increasing diameter. The guide fin 400 is fixed to the outer sleeve 100 instead of being connected by copper pipes, which reduces the impact of copper pipe connections on the internal airflow and ensures the stability of the spiral airflow. The small inlet effectively increases the airflow speed and reduces heat accumulation from the heat source, while the large outlet facilitates the use of high-speed airflow under high-heat conditions and can form a self-circulating heat convection enhancement effect.

[0029] Furthermore, a slanted groove is formed at the top center of the collection plate 320, and a motor 330 is installed in the slanted groove. The output end of the motor 330 is connected to a guide fan blade 340. The motor 330 is installed later, and its outer wall is connected to the collection plate 320. Multiple guide fan blades 340 are connected to its output end to achieve the purpose of exhausting internal air. Its air duct is fixed to reduce the impact of external airflow on its heat dissipation.

[0030] It is worth noting that a sleeve 200 is installed on the top of the outer sleeve 100, and an annular grille 210 is installed on the inner side of the top of the sleeve 200. The bottom of the annular grille 210 corresponds to the guide fan blade 340. The sleeve 200 and the annular grille 210 work together to form a relatively closed state. At the same time, the outer sleeve 100 and the sleeve 200 are detachably connected, which facilitates the subsequent installation and removal of the motor 330 and subsequent maintenance and cleaning of the entire equipment.

[0031] It is worth noting that the interior of the air guide plate 410 is hollow, and one side of the air guide plate 410 is inclined in the same direction as the inclination of the air guide fins 400. The fact that the air guide plate 410 and the air guide fins 400 are inclined in the same direction allows air to be lifted during airflow, improving airflow performance and enabling air to be lifted between each layer of the radiator through its internal air guide plate 410.

[0032] It is worth noting that the heat dissipation holes 120 on the base plate 110 are evenly spaced in a gourd shape, and the bottom of the diffuser plate 310 corresponding to the base plate 110 is a solid structure. The holes 120 near the diffuser plate 310 are smaller, while the holes near the outer sleeve 100 are larger, and the two holes are correspondingly gourd-shaped. This hole arrangement allows the heat dissipation rate of the outer heat dissipation holes 120 to be faster than that of the inner heat dissipation holes 120, preventing air convection and improving the orderliness of airflow.

[0033] Working Principle: This embodiment provides a spiral-guided cold-forged heat sink. In use, the base plate 110 contacts the computer components for heat conduction. The generated heat is discharged through the heat dissipation holes 120 on the base plate 110 into the bottom cavity between the outer sleeve 100 and the heat guide. The air is then directed by the diffuser plate 310 to the position of the guide fins 400. The air flows upwards through the rotation of the guide fan blades 340 driven by the top motor 330 output end. Simultaneously, the spiral arrangement of the guide fins 400 achieves spiral airflow. Upon reaching the position of the guide plate 410, the air rises and moves to the next layer of the heat sink, following the same pattern. The spiral flow and air lifting operation allow air to reach the collection plate 320 and then be discharged over a wide area by the rotation of the guide fan blades 340. At the same time, the temperature rise caused by the connection between the outer sleeve 100 and the base plate 110 during use is cooled by contact with the copper pipe 130 outside the outer sleeve 100. When the internal cavity is under negative pressure, low-temperature air intake is achieved through the slots 140. When the heat source temperature is high, the output speed of the motor 330 is increased, which, together with the rotation of the guide fan blades 340, increases the air flow speed inside the cavity. At this time, the wind pressure increases, the micro-motion plate 420 opens, and the air intake area is increased by lifting the air, thereby improving the heat dissipation efficiency.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
