Description

Technical Field

[0001] This invention relates to the field of host heat sink technology, specifically a host heat sink with an air-collecting and turbulence-inducing shroud. Background Technology

[0002] A computer cooler is a device used to dissipate heat from inside a computer. It absorbs the heat generated by electronic components such as the central processing unit (CPU), graphics card (GPU), motherboard chipset, and hard drive during high-speed operation, and then quickly conducts and dissipates this heat into the surrounding environment.

[0003] Chinese patent CN219778176U discloses an easily detachable and assembleable host computer heat sink, including a cooling fan device, connectors, and a plate-shaped heat dissipation structure. The cooling fan device has connectors around its perimeter, and the plate-shaped heat dissipation structure is located at its rear. The cooling fan device includes a frame, a fan, and connecting holes. The fan is housed inside the frame, and the connecting holes are located around its perimeter. In this easily detachable and assembleable host computer heat sink, the cooling fan device is engaged with the plate-shaped heat dissipation structure via connectors, and the connection between the cooling fan device and the plate-shaped heat dissipation structure is detachable, allowing for separate cleaning of the cooling fan device and the plate-shaped heat dissipation structure. The plate-shaped heat dissipation structure is connected to the host computer via clips; the user presses the front of the clips until a click is heard, completing the connection between the plate-shaped heat dissipation structure and the host computer.

[0004] However, the above-mentioned patent has the following shortcomings: its heat dissipation structure is simple, the cooling fan blows air directly onto the plate-shaped heat dissipation structure, the airflow is relatively dispersed and cannot form a concentrated pressurized airflow, resulting in limited heat dissipation efficiency; at the same time, it lacks targeted heat dissipation capabilities for other heat-generating components inside the host (such as graphics cards, memory, etc.), and no dust filtration and cleaning mechanism is set up. After long-term use, dust is easy to accumulate on the surface of the heat sink, further reducing the heat dissipation performance.

[0005] Therefore, the present invention provides a host heat sink with an air-collecting turbulence shroud. Summary of the Invention

[0006] The purpose of this invention is to provide a host heat sink with an air-collecting and turbulence-inducing shroud to solve the problems mentioned in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a host heat sink with an air collection and turbulence shroud, including a heat dissipation contact base and two heat dissipation fans, wherein heat dissipation fins are fixedly installed on the heat dissipation contact base, and further includes an air collection and turbulence mechanism, a dust collection mechanism and a flow distribution mechanism;

[0008] An air collection and turbulence mechanism is disposed between the heat dissipation fins and the two cooling fans. The air collection and turbulence mechanism includes a fixed shell that is fixedly installed on the heat dissipation fins. Two air collection connecting covers that are respectively fixed to the back of the two cooling fans are symmetrically fixedly installed on the fixed shell. A pressurization component is provided on the inner side of each air collection connecting cover. Two air outlet shells are fixedly installed on the fixed shell.

[0009] The dust collection mechanism is mounted on the fixed shell. The dust collection mechanism includes a mounting frame that is slidably mounted inside the fixed shell. A dust collection sponge block is slidably mounted inside the mounting frame. A middle partition is slidably mounted inside the dust collection sponge block. A warning component is provided on the fixed shell. An installation component is provided between the fixed shell and the mounting frame.

[0010] A flow diversion mechanism is provided between each cooling fan and the air collection connection cover. The flow diversion mechanism includes an airflow guiding component disposed between the cooling fan and the air collection connection cover, and an adaptive opening and closing component is provided on the airflow guiding component.

[0011] Furthermore, a pair of mounting blocks are symmetrically fixed on each of the heat dissipation fins.

[0012] Furthermore, the pressurization assembly includes an inner mounting frame fixedly installed inside the air collection connection cover. Multiple pairs of reset springs are symmetrically fixedly installed on the inner mounting frame. One end of each pair of reset springs is fixedly connected to the inner mounting frame, and the other end is a free end that is normally closed to each other and can be opened under airflow impact. Each pair of reset springs is arranged opposite to each other, and their free ends have a small gap to form an openable airflow channel.

[0013] Furthermore, the warning component includes a gas collecting shell fixedly installed on the inner wall of the fixed shell, the flared end of the gas collecting shell corresponding to the top end of the dust collecting sponge block, a transparent warning shell fixedly installed on the fixed shell, and the constricted end of the gas collecting shell communicating with the transparent warning shell.

[0014] Furthermore, a first spring is connected to the inner wall of the transparent warning shell, and a conspicuous identification piece is connected to the end of the first spring and slidably connected to the transparent warning shell.

[0015] Furthermore, the mounting assembly includes two guide rail housings fixedly mounted on the fixed housing, and each guide rail housing has a slider slidably mounted on its inner side.

[0016] Furthermore, a limiting sleeve is fixedly installed on the slider, a support rod is fixedly installed on the inner wall of the limiting sleeve, and a second spring is connected to the inner wall of the limiting sleeve.

[0017] Furthermore, the end of the second spring is connected to a side block that is slidably connected to the support rod, and a rubber movable block that is slidably connected to the mounting frame is fixedly installed between the two side blocks.

[0018] Furthermore, the airflow guiding assembly includes a guide shell fixedly installed on the air collection connection cover, an air gathering shell fixedly installed on the guide shell, two fastening threaded sleeves threadedly installed on the air gathering shell, and two movable guide tubes clamped and fixedly installed between the air gathering shell and the two fastening threaded sleeves, with a heat dissipation nozzle fixedly installed on each of the movable guide tubes.

[0019] Furthermore, the adaptive opening and closing assembly includes a bidirectional fixing sleeve fixedly installed on the inner wall of the gas-gathering shell. Two third springs are symmetrically connected to the inner wall of the bidirectional fixing sleeve. Each third spring has a telescopic block slidably connected to its end. A support plate is fixedly installed on the telescopic block. A first copper wire is bound to the support plate. The first copper wire passes through the inner side of the movable guide tube and the heat dissipation nozzle. A bimetallic strip is rotatably installed at the end of the heat dissipation nozzle. A second copper wire, which is bound to the other end of the first copper wire, is welded onto the bimetallic strip.

[0020] The beneficial effects of this invention are:

[0021] (1) The present invention controls the operation of the cooling fan so that the cooling fan can introduce the cooling airflow into the inside of the air collection connection cover, so that the airflow in the air collection connection cover pushes open the reset spring, so that an opening is created between each pair of reset springs that allows the airflow to pass through. The airflow passing through the opening is pressurized due to the narrow space, so that the pressurized airflow can enhance the heat dissipation effect on the heat dissipation fins. At the same time, the airflow size will also change due to the change of the cooling fan power. When the changed airflow impacts the reset spring, the reset spring will perform a corresponding opening and closing action. The instantaneous pulse generated by the opening and closing can clean the dust adhering to the heat dissipation fins. The cooled airflow rushes towards the dust collection mechanism and then flows to the top of the fixed shell, and finally flows to the outside of the host through the air outlet shell.

[0022] (2) The present invention can intercept and collect dust in the airflow by setting up a dust collection sponge block. The partition can prevent the airflow on both sides from colliding and canceling each other out. When the pores of the dust collection sponge block do not collect enough dust, part of the airflow in the fixed shell can flow into the inner side of the air collection shell through the dust collection sponge block, and flow into the inner side of the transparent warning shell through the air collection shell to blow the eye-catching sign. The eye-catching sign moves along the inner side of the transparent warning shell under the support of the first spring force. When the pores of the dust collection sponge block collect enough dust, the dust blocks the pores of the dust collection sponge block, so that the airflow cannot enter the inner side of the transparent warning shell through the air collection shell to blow the eye-catching sign. Users can confirm whether the dust collection sponge block needs to be replaced by observing the movement of the eye-catching sign.

[0023] (3) In this invention, when the dust collection sponge block is replaced, the rubber moving block is pulled and moved. The rubber moving block drives the side block to move along the support rod under the support of the second spring force. At the same time, the rubber moving block moves along the mounting frame. The rubber moving block drives the slider to move along the inner side of the guide rail shell through the side block, support rod and limit sleeve, so that the rubber moving block is separated from the mounting frame shell and no longer fixes the mounting frame shell. By moving the mounting frame shell out of the inner side of the fixed shell, the dust collection sponge block is moved out of the inner side of the mounting frame shell for replacement or dust cleaning. Then the dust collection sponge block for replacement or dust cleaning is moved into the inner side of the mounting frame shell. Then the mounting frame shell is moved back into the inner side of the fixed shell and fixed by the rubber moving block. This facilitates the quick replacement of the dust collection sponge block, prevents improper dust handling, and avoids the reduction of heat dissipation efficiency due to dust accumulation in the host heat sink.

[0024] (4) By tightening the fastening threaded sleeve, the fastening threaded sleeve no longer clamps and fixes the movable guide tube. The user moves the heat dissipation nozzle to other heat dissipation positions of the host by rotating the movable guide tube, and tightens the fastening threaded sleeve to fix the movable guide tube. When the heat dissipation position is high, the high temperature will affect the bending of the bimetallic strip, so that the bent bimetallic strip can relax the second copper wire, so that the second copper wire no longer pulls the first copper wire, so that the first copper wire no longer supports the support plate, so that the third spring can use its own elasticity to drive the support plate to move through the telescopic block, so that the area of ​​the support plate blocking the movable guide tube is reduced, so that more airflow in the gas collection shell can enter the inside of the heat dissipation nozzle through the movable guide tube, so that more airflow can be ejected through the heat dissipation nozzle to increase the heat dissipation capacity of the heat dissipation position; when the temperature of the heat dissipation position drops, the bimetallic strip recovers, so that the recovered bimetallic strip can pull the first copper wire by tightening the second copper wire, so that the first copper wire drives the support plate to move and reset.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1-11As shown, the present invention discloses a host heat sink with an air-collecting and turbulence-dispersing shroud, comprising a heat dissipation contact base 1 and two cooling fans 3. Heat dissipation fins 2 are fixedly mounted on the heat dissipation contact base 1, and a pair of mounting blocks 4 are symmetrically fixedly mounted on each heat dissipation fin 2. The system also includes an air-collecting and turbulence-dispersing mechanism, a dust collection mechanism, and a flow-diverting mechanism. The air-collecting and turbulence-dispersing mechanism is disposed between the heat dissipation fins 2 and the two cooling fans 3. The air-collecting and turbulence-dispersing mechanism includes a fixing shell 6 fixedly mounted on the heat dissipation fins 2, and two mounting blocks 4 symmetrically mounted on the fixing shell 6, respectively facing the back of the two cooling fans 3. A fixed gas collection connection hood 5 is provided with a pressurization component on the inner side of each gas collection connection hood 5. Two gas outlet shells 9 are fixedly installed on the fixed shell 6. The pressurization component includes an inner mounting frame 7 fixedly installed inside the gas collection connection hood 5. Multiple pairs of reset springs 8 are symmetrically fixedly installed on the inner mounting frame 7. One end of each pair of reset springs 8 is fixedly connected to the inner mounting frame 7, and the other end is a free end that is normally closed to each other and can be opened under the impact of airflow. Each pair of reset springs 8 is arranged opposite to each other, and their free ends have a small gap to form an openable and closable airflow channel.

[0040] Specifically, the mounting block 4 is fixed to the motherboard by using mounting screws, so that the heat dissipation contact base 1 can fit against the host. Both the heat dissipation contact base 1 and the heat dissipation fins 2 are made of aluminum alloy with high thermal conductivity to ensure efficient heat conduction. The heat dissipation fins 2 are surface-oxidized to enhance heat dissipation and corrosion resistance. When the host is running, the heat generated by the host is transferred to the heat dissipation fins 2 through the heat dissipation contact base 1, and the heat dissipation fan 3 runs to dissipate heat from the heat dissipation fins 2.

[0041] By controlling the operation of the cooling fan 3, the cooling fan 3 can introduce the cooling airflow into the inside of the air collection connection cover 5. The airflow inside the air collection connection cover 5 pushes open the reset spring 8, creating an opening between each pair of reset springs 8 that allows airflow to pass through. The airflow passing through the opening is pressurized due to the narrow space, which increases the cooling efficiency of the heat dissipation fins 2. At the same time, the airflow size will also change due to the change in the power of the cooling fan 3. When the changed airflow impacts the reset spring 8, the reset spring 8 will switch accordingly. The instantaneous pulse generated by the switch can clean the dust adhering to the heat dissipation fins 2. The cooled airflow rushes towards the dust collection mechanism and then flows to the top of the fixed shell 6, and finally flows to the outside of the host through the exhaust shell 9.

[0042] In this embodiment, the dust collection mechanism is mounted on the fixed shell 6. The dust collection mechanism includes a mounting frame 10 that is slidably mounted inside the fixed shell 6. A dust collection sponge block 11 is slidably mounted inside the mounting frame 10. A middle partition 12 is slidably mounted inside the dust collection sponge block 11. A warning component is provided on the fixed shell 6. A mounting component is provided between the fixed shell 6 and the mounting frame 10. The warning component includes an air collection shell 13 that is fixedly mounted on the inner wall of the fixed shell 6. The flared opening of the air collection shell 13 corresponds to the top end of the dust collection sponge block 11. A transparent warning shell 14 is fixedly mounted on the fixed shell 6. The constricted opening of the air collection shell 13 is connected to the transparent warning shell 14. A first spring 15 is connected to the inner wall of the transparent warning shell 14. The end of the first spring 15 is connected to a conspicuous identification piece 16 that is slidably connected to the transparent warning shell 14.

[0043] Specifically, the dust collection sponge block 11 is made of porous foam material, which has good air permeability and dust interception ability. The middle partition 12 is made of thin metal sheet to separate airflow channels. The transparent warning shell 14 is made of acrylic material, which makes it easy to observe the position of the internal conspicuous identification sheet 16. The conspicuous identification sheet 16 can be made of lightweight plastic sheet and coated with eye-catching color.

[0044] By setting up the dust-collecting sponge block 11, dust in the airflow can be intercepted and collected. The baffle can prevent the airflow on both sides from colliding and canceling each other out. When the pores of the dust-collecting sponge block 11 do not collect enough dust, part of the airflow in the fixed shell 6 can flow into the inner side of the air-collecting shell 13 through the dust-collecting sponge block 11, and then flow into the inner side of the transparent warning shell 14 through the air-collecting shell 13 to blow the conspicuous identification plate 16, so that the conspicuous identification plate 16 moves along the inner side of the transparent warning shell 14 under the support of the elastic force of the first spring 15. When the pores of the dust-collecting sponge block 11 collect enough dust, the dust blocks the pores of the dust-collecting sponge block 11, so that the airflow cannot enter the inner side of the transparent warning shell 14 through the air-collecting shell 13 to blow the conspicuous identification plate 16. Users can confirm whether the dust-collecting sponge block 11 needs to be replaced by observing the movement of the conspicuous identification plate 16.

[0045] In this embodiment, the mounting assembly includes two guide rail housings 17 fixedly mounted on the fixed housing 6. A slider 18 is slidably mounted on the inner side of each guide rail housing 17. A limiting sleeve 19 is fixedly mounted on the slider 18. A support rod 20 is fixedly mounted on the inner wall of the limiting sleeve 19. A second spring 21 is connected to the inner wall of the limiting sleeve 19. The end of the second spring 21 is connected to a side block 22 that is slidably connected to the support rod 20. A rubber moving block 23 that is slidably connected to the mounting frame housing 10 is fixedly mounted between the two side blocks 22.

[0046] Specifically, the guide rail housing 17 can be made of aluminum alloy, and the rubber moving block 23 is made of elastic rubber material, which facilitates tight fit with the mounting frame housing 10 and provides fixation.

[0047] When the dust collection sponge block 11 is replaced, the rubber moving block 23 is pulled and moved. The rubber moving block 23 drives the side block 22 to move along the support rod 20 under the support of the second spring 21. At the same time, the rubber moving block 23 moves along the mounting frame 10. The rubber moving block 23, through the side block 22, the support rod 20 and the limiting sleeve 19, drives the slider 18 to move along the inner side of the guide rail shell 17, so that the rubber moving block 23 separates from the mounting frame 10, so that the rubber moving block 23 no longer moves against the mounting frame 10. To fix the dust collection sponge block 11, the mounting frame 10 is moved out of the inner side of the fixing shell 6, and the dust collection sponge block 11 is moved out of the inner side of the mounting frame 10 for replacement or dust cleaning. Then, the dust collection sponge block 11 is moved back into the inner side of the mounting frame 10, and the mounting frame 10 is moved back into the inner side of the fixing shell 6. The rubber moving block 23 is used for fixation, which facilitates the quick replacement of the dust collection sponge block 11, prevents improper dust handling, and avoids the reduction of heat dissipation efficiency due to dust accumulation inside the host heat sink.

[0048] In this embodiment, a flow-diverting mechanism is provided between each cooling fan 3 and the air-collecting connection cover 5. The flow-diverting mechanism includes an airflow guiding component disposed between the cooling fan 3 and the air-collecting connection cover 5. An adaptive opening and closing component is provided on the airflow guiding component. The airflow guiding component includes a guide shell 24 fixedly installed on the air-collecting connection cover 5. An air-gathering shell 25 is fixedly installed on the guide shell 24. Two fastening threaded sleeves 26 are threadedly installed on the air-gathering shell 25. Two movable ducts 27 are clamped and fixedly installed between the air-gathering shell 25 and the two fastening threaded sleeves 26. A heat dissipation nozzle 28 is fixedly installed on each movable duct 27. The adaptive opening and closing assembly includes a bidirectional fixing sleeve 29 fixedly installed on the inner wall of the gas-gathering shell 25. Two third springs 30 are symmetrically connected to the inner wall of the bidirectional fixing sleeve 29. Each third spring 30 has a telescopic block 31 slidably connected to the end of the end of the telescopic block 31. A support plate 32 is fixedly installed on the telescopic block 31. A first copper wire 33 is bound to the support plate 32. The first copper wire 33 passes through the inner side of the movable conduit 27 and the heat dissipation nozzle 28. A bimetallic strip 34 is rotatably installed at the end of the heat dissipation nozzle 28. A second copper wire 35 is welded to the bimetallic strip 34 and bound to the other end of the first copper wire 33.

[0049] Specifically, the gas-gathering shell 25 and the guide shell 24 can be injection molded from engineering plastics, the movable conduit 27 can be made of metal corrugated pipe, which is easy to bend and adjust the direction, the heat dissipation nozzle 28 is made of aluminum alloy material with good thermal conductivity and is provided with small nozzles to enhance the airflow speed, and the bimetallic strip 34 is made of two metals with different coefficients of thermal expansion, which bends and deforms when heated.

[0050] By tightening the fastening threaded sleeve 26, the user can remove the clamping and fixing of the movable guide tube 27. The user can then rotate the movable guide tube 27 to move the heat dissipation nozzle 28 to other locations on the main unit requiring heat dissipation. Tightening the fastening threaded sleeve 26 will then fix the movable guide tube 27. When the heat dissipation location is high, the high temperature will affect the bending of the bimetallic strip 34, allowing the bent bimetallic strip 34 to loosen the second copper wire 35. This prevents the second copper wire 35 from pulling on the first copper wire 33, thus relieving the first copper wire 33 of its supporting function on the support plate 32. The third spring 30 can use its own elastic force to drive the support plate 32 to move through the telescopic block 31, thereby reducing the area of ​​the support plate 32 that blocks the movable duct 27. This allows more airflow in the gas-gathering shell 25 to enter the inside of the heat dissipation nozzle 28 through the movable duct 27, and more airflow to be ejected through the heat dissipation nozzle 28, thus increasing the heat dissipation capacity of the heat dissipation location. When the temperature of the heat dissipation location drops, the bimetallic strip 34 returns to its original position. The returned bimetallic strip 34 can pull the first copper wire 33 by tightening the second copper wire 35, causing the first copper wire 33 to drive the support plate 32 to move and reset.

[0051] Working principle: The mounting block 4 is fixed to the motherboard using mounting screws, allowing the heat dissipation contact base 1 to fit against the host. By tightening the fastening threaded sleeve 26, the user can rotate the movable guide tube 27 to move the heat dissipation nozzle 28 to other locations on the host that require heat dissipation. Tightening the fastening threaded sleeve 26 secures the movable guide tube 27. When the host is running, the heat generated by the host is transferred to the heat dissipation fins 2 through the heat dissipation contact base 1. By controlling the operation of the cooling fan 3, the cooling fan 3 can introduce airflow into the inside of the air collection connection cover 5. The airflow inside the air collection connection cover 5 pushes open the reset springs 8, creating an opening between each pair of reset springs 8 that allows airflow to pass through. The airflow through the opening is pressurized due to the confined space, increasing its cooling efficiency on the heat sink 2. Simultaneously, the airflow magnitude changes with the power of the cooling fan 3, causing the reset spring 8 to switch on and off upon impact. The instantaneous pulse generated by this switching action cleans dust adhering to the heat sink 2. The cooled airflow then flows towards the dust collection mechanism and then towards the top of the mounting shell 6, ultimately exiting through the exhaust shell 9 to the outside of the host. When the pores of the dust collection sponge block 11 do not collect enough dust, some airflow within the mounting shell 6 can flow through the dust collection sponge block 11 into the inner side of the air collection shell 13, and then through the air collection shell 13 to the outside of the host. The inner side of the warning shell 14 blows on the conspicuous identification plate 16, causing the conspicuous identification plate 16 to move along the inner side of the transparent warning shell 14 under the support of the first spring 15. When the heat in the area requiring heat dissipation is high, the high temperature will affect the bending of the bimetallic strip 34, allowing the bent bimetallic strip 34 to relax the second copper wire 35. This prevents the second copper wire 35 from pulling the first copper wire 33 taut, and the first copper wire 33 from supporting the support plate 32. This allows the third spring 30 to use its own elasticity to move the support plate 32 through the telescopic block 31, reducing the area of ​​the support plate 32 that obstructs the movable duct 27, allowing more airflow inside the gas-gathering shell 25 to pass through the movable duct. 27 enters the inner side of the heat dissipation nozzle 28, allowing more airflow to be ejected through the heat dissipation nozzle 28 to increase the heat dissipation capacity of the heat dissipation location; when the temperature of the heat dissipation location drops, the bimetallic strip 34 recovers, allowing the recovered bimetallic strip 34 to pull the first copper wire 33 by tightening the second copper wire 35, causing the first copper wire 33 to drive the support plate 32 to move and reset; when enough dust is collected in the pores of the dust collection sponge block 11, the dust blocks the pores of the dust collection sponge block 11, preventing airflow from entering the inner side of the transparent warning shell 14 through the air collection shell 13 to blow the conspicuous identification plate 16, and the user can confirm whether the dust collection sponge block 11 needs to be replaced by observing the activity of the conspicuous identification plate 16;

[0052] When the dust collection sponge block 11 is replaced, by pulling and moving the rubber moving block 23, the rubber moving block 23 drives the side block 22 to move along the support rod 20 under the support of the second spring 21. At the same time, the rubber moving block 23 moves along the mounting frame 10. The rubber moving block 23 drives the slider 18 to move along the inner side of the guide rail shell 17 through the side block 22, the support rod 20 and the limiting sleeve 19, so that the rubber moving block 23 is separated from the mounting frame 10 and no longer fixes the mounting frame 10. By moving the mounting frame 10 out of the inner side of the fixing shell 6, the dust collection sponge block 11 is moved out of the inner side of the mounting frame 10 for replacement or dust cleaning. Then the dust collection sponge block 11 that has been replaced or cleaned is moved back into the inner side of the mounting frame 10. Then the mounting frame 10 is moved back into the inner side of the fixing shell 6 and fixed by the rubber moving block 23, so that the dust collection sponge block 11 can be replaced quickly.
