Description
Technical Field
[0001] This utility model relates to the field of chassis technology, and in particular to a chassis with external circulation heat dissipation. Background Technology
[0002] A heatsink is a device that helps dissipate heat from electronic devices. By using a heatsink, electronic devices can maintain a stable internal temperature, ensuring that electronic components operate within a safe temperature range, thereby guaranteeing the performance and reliability of the device.
[0003] Most existing heat sinks use air cooling. While air cooling can help dissipate heat from electronic devices, their large size makes it difficult for users to move them according to their needs, resulting in inconvenience. Therefore, we propose an externally circulating heat sink. Utility Model Content
[0004] To address the technical problem of existing heat dissipation boxes being inconvenient to use, this utility model provides a heat dissipation box with external circulation.
[0005] This utility model adopts the following technical solution: an externally circulating heat dissipation box includes a base and a shell disposed above the base. A sliding groove is provided on the side of the base near the shell. A mounting plate is slidably connected inside the sliding groove. The shell is fixed to the top side of the mounting plate. An axial flow fan is fixed to one end of the shell. The sliding groove is provided on the base. A threaded post with one end fixed to the bottom side of the mounting plate slides through the sliding groove. A limiting sleeve is threaded onto the outer wall of the threaded post away from the mounting plate. The top side of the limiting sleeve contacts the bottom side of the base. Through the cooperation of the above components, the electronic equipment inside the shell can circulate and interact with the outside air, thereby reducing the temperature of the electronic equipment inside the shell. The corresponding positions of the mounting plate and the shell can be adjusted, and the corresponding angles of the shell and its internal electronic equipment can be adjusted, making it convenient for users to remove the mounting plate, shell and its internal electronic equipment from the base.
[0006] As a further improvement to the above solution, a support block is fixed to the bottom side of one end of the base, and an installation block is fixed to the bottom side of the mounting plate away from the support block. The mounting block has a loading groove, and a loading block is slidably inserted into the loading groove. A locking block is fixed to the top side of the loading block, and the end of the locking block away from the loading block extends to the top of the mounting plate. A snap-fit block is fixed to the top side of the loading block outside the loading groove. A snap-fit groove is opened on the bottom side of the base near the mounting block, and the snap-fit block slides inside the snap-fit groove. A pulley plate is fixed to the end of the mounting block away from the mounting plate, and universal wheels are fixed to both ends of the bottom side of the pulley plate. Through the cooperation of the snap-fit block and the snap-fit groove, the mounting plate can be confined inside the base. Pressing the locking block causes it to move vertically downward, causing the loading block and the snap-fit block to move vertically downward. When the snap-fit block separates from the snap-fit groove, the mounting plate can be pulled to adjust it. The universal wheels facilitate the displacement and deflection of the mounting plate.
[0007] As a further improvement to the above solution, the mounting plate has a slot at one end near the mounting block, and the top of the mounting block has a movable groove. The block slides inside the slot and the movable groove. The slot prevents the mounting plate from interfering with the vertical displacement of the block.
[0008] As a further improvement to the above solution, a rubber sheet is bonded to the bottom of the support block. The bottom side of the rubber sheet and the bottom side of the caster are at the same horizontal height. The stability of the box can be improved by the rubber sheet being at the same horizontal height as the bottom side of the caster.
[0009] As a further improvement to the above solution, the outer wall of the limiting sleeve is provided with anti-slip texture, and the diameter of the limiting sleeve is larger than the width of the sliding groove opening. The anti-slip texture makes it convenient for the user to rotate the limiting sleeve.
[0010] As a further improvement to the above solution, an inspection port is provided on the outer side of the housing, and a cover for sealing the inspection port is threaded onto the outer side of the housing. By unscrewing the bolts on the cover and removing it from the housing, the user can inspect and maintain the electronic equipment inside the housing through the inspection port.
[0011] As a further improvement to the above solution, a plurality of return springs are fixed on the bottom side of the loading block. The end of the return spring away from the loading block is fixed on the inner wall of the bottom of the loading groove. The return spring can push the displaced loading block to return to its original displacement.
[0012] As a further improvement to the above solution, the length of the loading slot opening is greater than the length of the locking block located above the mounting plate, and the length of the locking block located above the mounting plate is greater than the height of the locking block. With a suitable loading slot opening length, the locking block can be disengaged from the interior of the locking slot.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model, through the coordinated operation of a base, housing, sliding groove, mounting plate, axial flow fan, threaded column, limiting sleeve, mounting block, pulley plate, universal wheel, loading block, locking block, return spring, locking block, locking groove, support block, chassis cover, and sliding groove, helps the electronic equipment inside the heat sink to circulate and interact with the outside air, thereby reducing the temperature of the electronic equipment inside the heat sink. The position of the heat sink can be adjusted according to usage requirements, and the angle of the heat sink can be easily adjusted. Users can easily remove the electronic equipment inside the heat sink from the base, thus facilitating inspection and maintenance. It is convenient to use.
[0015] In summary, this utility model has a reasonable structure, which can help the electronic equipment inside the heat sink to circulate and interact with the outside air. It can adjust the corresponding position and angle of the heat sink, and allows users to easily remove the electronic equipment inside the heat sink from the base. It is highly flexible and easy to use. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example 1:
[0027] Combination Figure 1 , Figure 2 , Figure 5 This embodiment of an externally circulating heat dissipation box includes a base 1 and a housing 2 disposed above the base 1. A sliding groove 3 is provided on the side of the base 1 near the housing 2. A mounting plate 4 is slidably connected inside the sliding groove 3. The housing 2 is fixed to the top side of the mounting plate 4. An axial flow fan 5 is fixed to one end of the housing 2. The housing 2 has ventilation holes. A sliding groove 18 is provided on the base 1. A threaded post 6 with one end fixed to the bottom side of the mounting plate 4 slides through the sliding groove 18. A limiting sleeve 7 is threadedly sleeved on the outer wall of the threaded post 6 away from the mounting plate 4. The top side of the limiting sleeve 7 contacts the bottom side of the base 1.
[0028] The implementation principle of the externally circulating heat dissipation box in this embodiment is as follows: When the electronic equipment inside the housing 2 needs heat dissipation, the operation of the axial flow fan 5, in conjunction with the ventilation holes, helps the electronic equipment inside the housing 2 to circulate and interact with the outside air, thereby reducing the temperature of the electronic equipment inside the housing 2. When the user needs to adjust the position of the electronic equipment inside the housing 2 during the use of the heat dissipation box, the mounting plate 4 can be pulled. Through the sliding engagement of the mounting plate 4 and the sliding groove 3, and through the sliding engagement of the threaded column 6 and the sliding groove 18, the mounting plate 4 is moved, causing the housing 2 to move as well. At this time, the electronic equipment can be adjusted. Adjust the corresponding position of the sub-device, move the mounting plate 4, and through the sliding engagement of the threaded post 6 and the sliding groove 18, the mounting plate 4 can be deflected. At this time, the corresponding angle of the mounting plate 4 can be adjusted, thereby adjusting the corresponding angle of the housing 2 and its internal electronic equipment. Rotate the limiting sleeve 7, and through the threaded engagement of the limiting sleeve 7 and the threaded post 6, the limiting sleeve 7 can be moved vertically. When the limiting sleeve 7 is disengaged from the outside of the threaded post 6, the mounting plate 4 can be pulled, causing the mounting plate 4 to move vertically. When the threaded post 6 on the mounting plate 4 is disengaged from the sliding groove 18, the mounting plate 4, the housing 2 and its internal electronic equipment are removed from the base 1.
[0029] Example 2:
[0030] Combination Figure 3 , Figure 4 , Figure 6 and Figure 7This embodiment, based on embodiment 1, further improves upon the following: a support block 16 is fixed to the bottom side of one end of the base 1; an mounting block 8 is fixed to the bottom side of the mounting plate 4 away from the support block 16; the mounting block 8 has a loading groove; a loading block 11 is slidably inserted into the loading groove; a locking block 12 is fixed to the top side of the loading block 11; the end of the locking block 12 away from the loading block 11 extends to the top of the mounting plate 4; a snap-fit block 14 is fixed to the top side of the loading block 11 outside the loading groove; a snap-fit groove 15 is formed on the bottom side of the base 1 near the mounting block 8; and the snap-fit block 14 slides... Inside the snap-fit groove 15, the mounting block 8 is fixed with a pulley plate 9 at one end away from the mounting plate 4. The two ends of the bottom side of the pulley plate 9 are fixed with casters 10. Through the cooperation of the snap-fit groove 15 and the mounting block 14, the mounting plate 4 can be confined inside the base 1. Pressing the snap-fit block 12 will cause the snap-fit block 12 to move vertically downward, causing the loading block 11 and the snap-fit block 14 to move vertically downward. When the snap-fit block 14 is separated from the snap-fit groove 15, the mounting plate 4 can be pulled to adjust the mounting plate 4. Through the casters 10, the mounting plate 4 can be easily moved and deflected.
[0031] The mounting plate 4 has a slot at one end near the mounting block 8, and the top of the mounting block 8 has a movable groove. The locking block 12 slides inside the slot and the movable groove. The slot prevents the mounting plate 4 from interfering with the vertical displacement of the locking block 12.
[0032] A rubber sheet is glued to the bottom of the support block 16. The bottom side of the rubber sheet and the bottom side of the caster 10 are at the same level. The stability of the box can be improved by the rubber sheet being at the same level as the bottom side of the caster 10.
[0033] The outer wall of the limited sleeve 7 is provided with anti-slip texture. The diameter of the limited sleeve 7 is larger than the width of the groove of the sliding groove 18. The anti-slip texture makes it easy for the user to rotate the limited sleeve 7.
[0034] An inspection port is provided on the outside of the housing 2. A cover 17 for closing the inspection port is threaded onto the outside of the housing 2. By unscrewing the bolts on the cover 17 and removing the cover 17 from the housing 2, the user can inspect and maintain the electronic equipment inside the housing 2 through the inspection port.
[0035] Multiple return springs 13 are fixed to the bottom side of the loading block 11. The end of the return spring 13 away from the loading block 11 is fixed to the inner wall of the bottom of the loading groove. The return spring 13 can push the displaced loading block 11 to return to its original position.
[0036] The length of the loading slot opening is greater than the length of the locking block 12 located above the mounting plate 4, and the length of the locking block 12 located above the mounting plate 4 is greater than the height of the locking block 14. With a suitable loading slot opening length, the locking block 14 can be disengaged from the interior of the locking slot 15.
[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
