Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation chassis, and particularly to a 6U board heat dissipation chassis. Background Art

[0002] A 6U circuit board usually refers to a standardized circuit board. Currently, 6U circuit boards are most widely used inside computer chassis. Through their comprehensive performance in terms of signal integrity, system stability, cost advantages, and technical advantages, 6U circuit boards provide users with an efficient, reliable, and economical solution.

[0003] Currently, corresponding heat dissipation structures are provided inside the chassis to prevent the 6U circuit board from being damaged due to excessive temperature during use. The existing heat dissipation structures inside the chassis mainly rely on air cooling.

Detailed implementation manner

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0037] As Figures 1-10 shown, the embodiment of the present invention provides a 6U board heat dissipation chassis, including a chassis main body 1, and the chassis main body 1 is assembled by a front plate 101, a top plate 102, a right plate 103, a rear plate 104, a left plate 105 and a bottom plate 106. Through holes 5 are provided on the front plate 101, the top plate 102, the rear plate 104 and the bottom plate 106. The provision of the through holes 5 facilitates the installation of the first fixing frame 701 and the second fixing frame 801, thereby realizing the replacement of the positions of the air inlet 702 and the air outlet 802, effectively solving the problem of low heat dissipation efficiency caused by the blockage of the air inlet or the air outlet. A rotating shaft 6 is fixedly connected to the right plate 103 and the left plate 105. The provision of the rotating shaft 6 facilitates the rotation of the air inlet assembly 7 and the air outlet assembly 8. The air inlet assembly 7 and the air outlet assembly 8 are rotatably connected to the circumferential surface of the rotating shaft 6;

[0038] The air inlet assembly 7 includes a first fixed frame 701, an air inlet 702, a first connecting shaft 707, a first connecting rod 708, a first sliding cavity 709, a first sliding plate 7010, a first sliding rod 7011 and a first spring 7012. The first fixed frame 701 is mainly used for installing and fixing the first filter screen 703 and the air inlet motor 705. The setting of the first connecting shaft 707 facilitates the rotation of the first fixed frame 701. During the later maintenance and repair of the air inlet motor 705, only the first fixed frame 701 needs to be flipped, and the chassis main body 1 does not need to be disassembled, and the operation is relatively simple. The settings of the first sliding cavity 709, the first sliding plate 7010, the first sliding rod 7011 and the first spring 7012 facilitate the sliding of the first sliding rod 7011 inside the first connecting rod 708, so that the relative length between the first sliding rod 7011 and the first connecting rod 708 changes. The first spring 7012 is always in a compressed state. By using the elastic force of the first spring 7012 to squeeze the first sliding plate 7010, the first sliding rod 7011 enters the inside of the first connecting rod 708. When the first fixed frame 701 enters the inside of the through hole 5, the first spring 7012 can also prevent the first fixed frame 701 from falling off from the inside of the through hole 5. Both the first sliding rod 7011 and the first connecting rod 708 are square rods;

[0039] The air inlet 702 is arranged inside the first fixed frame 701 and penetrates through the first fixed frame 701. The first connecting shaft 707 is rotatably connected to the left and right side walls of the first fixed frame 701. The first connecting rod 708 is fixedly connected to the other end of the first connecting shaft 707. The first sliding cavity 709 is arranged inside the first connecting rod 708. The first sliding plate 7010 is slidably connected inside the first sliding cavity 709. The first sliding rod 7011 is fixedly connected to the bottom of the first sliding plate 7010. The first spring 7012 is sleeved on the first sliding rod 7011. The bottom end of the first sliding plate 7010 is rotatably connected to the rotating shaft 6;

[0040] The air inlet assembly 7 further includes a first filter screen 703, a first fixing bracket 704, an air inlet motor 705, and an air inlet fan blade 706. The first filter screen 703 is mainly used for filtering dust. The first fixing bracket 704 is mainly used for fixing the air inlet motor 705, but the first fixing bracket 704 does not affect the flow of air. The air inlet motor 705 is mainly used for controlling the rotation of the air inlet fan blade 706, so as to blow the external gas into the inside of the chassis main body 1 for heat dissipation;

[0041] The first filter screen 703 and the first fixing bracket 704 are both fixedly connected to the inner wall of the air inlet 702, and the first filter screen 703 is located above the first fixing bracket 704. The air inlet motor 705 is fixedly connected to the bottom of the first fixing bracket 704. The air inlet fan blade 706 is fixedly connected to the output shaft of the air inlet motor 705. The number of air inlet motors 705 is set to be multiple and is evenly distributed at the bottom of the first fixing bracket 704.

[0042] The air outlet assembly 8 includes a second fixing frame 801, an air outlet 802, a second connecting shaft 807, a second connecting rod 808, a second sliding cavity 809, a second sliding plate 8010, a second sliding rod 8011 and a second spring 8012. The air outlet 802 is arranged inside the second fixing frame 801 and penetrates through the second fixing frame 801. The second connecting shaft 807 is rotatably connected to the left and right side walls of the second fixing frame 801. The second connecting rod 808 is fixedly connected to the other end of the second connecting shaft 807. The second sliding cavity 809 is arranged inside the second connecting rod 808. The second sliding plate 8010 is slidably connected inside the second sliding cavity 809. The second sliding rod 8011 is fixedly connected to the top of the second sliding plate 8010. The second spring 8012 is sleeved on the second sliding rod 8011. The top end of the second sliding rod 8011 is rotatably connected to the rotating shaft 6, and the second sliding rod 8011 is located outside the first sliding rod 7011.

[0043] The air outlet assembly 8 further includes a second filter screen 803, a second fixing bracket 804, an air outlet motor 805, and an air outlet fan blade 806. The second filter screen 803 and the second fixing bracket 804 are both fixedly connected to the inner wall of the air outlet 802, and the second filter screen 803 is located above the second fixing bracket 804. The air outlet motor 805 is fixedly connected to the top of the second fixing bracket 804. The air outlet fan blade 806 is fixedly connected to the output shaft of the air outlet motor 805. The number of air outlet motors 805 is set to be multiple and is evenly distributed at the top of the second fixing bracket 804.

[0044] The structure of the air outlet assembly 8 is the same as that of the air inlet assembly 7, and the operation method is also the same, so it will not be elaborated here. The difference between the air outlet assembly 8 and the air inlet assembly 7 is that the air outlet motor 805 on the air outlet assembly 8 controls the rotation of the air outlet fan blade 806 and discharges the hot air inside the chassis main body 1.

[0045] The front and rear side walls of the first connecting rod 708 and the second connecting rod 808 are fixedly connected with a handle 9. The setting of the handle 9 facilitates the movement of the first connecting rod 708 or the second connecting rod 808, so that the first fixing frame 701 or the second fixing frame 801 is moved out from the inside of the through hole 5, and the first fixing frame 701 or the second fixing frame 801 is controlled to rotate around the rotating shaft 6, so as to rotate the air inlet 702 or the air outlet 802 to a suitable position. The internal thread of the handle 9 is connected with a fastening bolt 10. When the fastening bolt 10 is screwed into the inside of the corresponding fixing hole 11, the first The fixed frame 701 or the second fixed frame 801 is fixed to prevent the first fixed frame 701 or the second fixed frame 801 from rotating, thereby ensuring the stability of the air inlet motor 705 and the air outlet motor 805 during operation. Fixing holes 11 are provided on the left and right side walls of the first fixed frame 701 and the second fixed frame 801, and sealing components 12 are provided on the front plate 101, the top plate 102, the rear plate 104 and the bottom plate 106, and the sealing components 12 are arranged corresponding to the through holes 5. The sealing components 12 mainly block the unused through holes 5 to prevent external dust from entering the interior of the chassis body 1.

[0046] The blocking assembly 12 includes a storage groove 1201, a telescopic rod 1202, a blocking plate 1203, a third spring 1204, a toggle rod 1205 and a concave hole 1206, wherein the storage groove 1201 is mainly used to store the blocking plate 1203. When the first fixing frame 701 or the second fixing frame 801 enters the interior of the through hole 5, the blocking plate 1203 will be stored in the storage groove 1201. The telescopic rod 1202 itself has a telescopic effect, which mainly acts on the blocking plate 1203. The movement of the blocking plate 1203 is limited, the third spring 1204 is always in a compressed state, and the blocking plate 1203 is squeezed by the elastic force of the third spring 1204. When the first fixing frame 701 or the second fixing frame 801 is moved out from the inside of the through hole 5, the blocking plate 1203 automatically blocks the through hole 5 under the action of the third spring 1204. The setting of the toggle rod 1205 is mainly to push the blocking plate 1203 into the inside of the storage groove 1201.

[0047] The storage groove 1201 is arranged on the side wall of the through hole 5, the telescopic rod 1202 is fixedly connected to the inner wall of the storage groove 1201 away from the through hole 5, the blocking plate 1203 is fixedly connected to the other end of the telescopic rod 1202, the third spring 1204 is sleeved on the telescopic rod 1202, the toggle rod 1205 is fixedly connected to the outer side of the blocking plate 1203, the recessed hole 1206 is arranged on the outer side of the storage groove 1201, and the toggle rod 1205 is arranged corresponding to the recessed hole 1206, and each blocking assembly 12 is provided with two telescopic rods 1202 and two third springs 1204, and are symmetrically arranged on the left and right sides of the blocking plate 1203.

[0048] On the inner walls of the right plate 103 and the left plate 105, there are mounting seats 2 fixedly connected. On the side wall of the mounting seat 2, there is a slot 3. Inside the slot 3, a 6U circuit board 4 is snap-fitted. On the front side wall of the front plate 101, there is a control panel 14. On the rear side wall of the rear plate 104, there are a plurality of connection jacks 15. And both the control panel 14 and the plurality of connection jacks 15 are located above the through hole 5. At the four corner positions of the bottom of the bottom plate 106, there are support legs 13 fixedly connected.

[0049] The first fixing frame 701 and the second fixing frame 801 are both adapted to the through hole 5. The first sliding rod 7011 is slidably connected to the first connecting rod 708. The first spring 7012 is located inside the first sliding cavity 709. The second sliding rod 8011 is slidably connected to the second connecting rod 808. The second spring 8012 is located inside the second sliding cavity 809. On both the first fixing frame 701 and the second fixing frame 801, there are four fastening bolts 10 and four fixing holes 11.

[0050] From Figure 1 、 Figure 2 and Figure 10 As can be seen, corresponding wire passing holes are provided on both the right plate 103 and the rotating shaft 6 (the wire passing holes are relatively small, and the wire body will be stuck in the wire passing holes, and the wire body will move only under a huge external force, effectively preventing the wire body from falling off the main board. In addition, dust cannot enter the interior of the chassis main body 1). The main purpose is to facilitate the connection of the wire bodies of the air intake motor 705 and the air outlet motor 805 to the main board inside the chassis main body 1. The wire body on the air intake motor 705 passes through the wire passing hole on the right plate 103, and the wire body on the air outlet motor 805 passes through the wire passing hole on the rotating shaft 6. In addition, the wire bodies on the air intake motor 705 and the air outlet motor 805 are long enough. At the same time, they can be fixed to the corresponding connecting rods by tie straps, or symmetrically arranged card slots (not shown in the figure) can be provided on the corresponding connecting rods to fix the wire bodies. The wire bodies located outside are reserved with enough length to facilitate telescoping or rotating together with the corresponding connecting rods. The rotating angles of the air intake assembly 7 and the air outlet assembly 8 do not exceed 360 degrees to avoid wire body entanglement;

[0051] Working principle: When in use, first adjust the positions of the air inlet 702 and the air outlet 802 according to the placement position or installation position of the chassis main body 1. First, pull the first connecting rod 708 through the grip 9, and move the first fixing frame 701 out of the through hole 5. At this time, the blocking plate 1203 automatically blocks the through hole 5 under the action of the third spring 1204. Then, rotate around the rotating shaft 6, and when the first fixing frame 701 is rotated to a suitable position, first push the blocking plate 1203 through the toggle lever 1205, and push the blocking plate 1203 into the storage groove 1201. When the toggle lever 1205 enters the concave hole 1206, the blocking plate 1203 completely enters the storage groove 1201. Then, slowly release the grip 9, and the first fixing frame 701 is fixed inside the through hole 5 under the action of the first spring 7012, thus realizing the position adjustment of the air inlet 702. The position adjustment method of the air outlet 802 is the same as that of the air inlet 702. During the working process, the air inlet motor 705 and the air outlet motor 805 start working at the same time. The air inlet motor 705 blows the external cold air into the chassis main body 1 and dissipates heat from the 6U circuit board 4 during the working process. At the same time, the air outlet motor 805 discharges the heat generated by the 6U circuit board 4, thus realizing heat dissipation. When the air inlet motor 705, the air inlet fan blade 706, the air outlet motor 805, and the air outlet fan blade 806 need to be repaired or replaced, first move the first fixing frame 701 out of the through hole 5 through the grip 9. At this time, the blocking plate 1203 automatically blocks the through hole 5 under the action of the third spring 1204. Then, rotate around the rotating shaft 6, and rotate the first fixing frame 701 to a position deviating from the through hole 5. Then, screw out the fastening bolt 10 from the fixing hole 11, and then turn the first fixing frame 701 by 180°. Then, the repair or replacement of the air inlet motor 705 and the air inlet fan blade 706 can be carried out. The repair or replacement of the air outlet motor 805 and the air outlet fan blade 806 is the same as that of the air inlet motor 705 and the air inlet fan blade 706, which will not be elaborated here.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
