DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] like Figure 1-10 As shown, the embodiment of the present invention provides a 6U board heat dissipation chassis, including a chassis body 1, and the chassis 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. The front plate 101, the top plate 102, the rear plate 104 and the bottom plate 106 are all provided with through holes 5. 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, and effectively solving the problem of low heat dissipation efficiency caused by the blockage of the air inlet or the air outlet. The right plate 103 and the left plate 105 are fixedly connected with a rotating shaft 6. The provision of the rotating shaft 6 facilitates the rotation of the air inlet component 7 and the air outlet component 8. The air inlet component 7 and the air outlet component 8 are rotatably connected on the circumferential surface of the rotating shaft 6. 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 slide plate 7010, a first slide bar 7011 and a first spring 7012, wherein the first fixed frame 701 is mainly used for installing and fixing the first filter 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 inspection and maintenance of the air inlet motor 705, it is only necessary to flip the first fixed frame 701 without disassembling the chassis body 1, and the operation is relatively simple. The first sliding cavity 709, the first slide plate 7010, the first slide bar 7011 and the first spring 7012 The arrangement of a slide bar 7011 and a first spring 7012 facilitates the first slide bar 7011 to slide inside the first connecting rod 708, so that the relative lengths of the first slide bar 7011 and the first connecting rod 708 change. The first spring 7012 is always in a compressed state. The first slide plate 7010 is squeezed by the elastic force of the first spring 7012, so that the first slide bar 7011 enters the first connecting rod 708. When the first fixed frame 701 enters the through hole 5, the first spring 7012 can also prevent the first fixed frame 701 from falling off from the through hole 5.

There are multiple air inlet motors 705, and they are evenly distributed at the bottom of the first fixed bracket 704.

[0022] The air outlet assembly 8 includes a second fixed frame 801, an air outlet 802, a second connecting shaft 807, a second connecting rod 808, a second sliding cavity 809, a second slide plate 8010, a second sliding rod 8011 and a second spring 8012. The air outlet 802 is arranged inside the second fixed frame 801 and passes through the second fixed frame 801. The second connecting shaft 807 is rotatably connected to the left and right side walls of the second fixed 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 slide 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 slide 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 on the outside of the first sliding rod 7011. The air outlet assembly 8 also includes a second filter 803, a second fixed bracket 804, an air outlet motor 805, and an air outlet fan blade 806. The second filter 803 and the second fixed bracket 804 are fixedly connected to the inner wall of the air outlet 802, and the second filter 803 is located above the second fixed bracket 804. The air outlet motor 805 is fixedly connected to the top of the second fixed bracket 804. The air outlet fan blade 806 is fixedly connected to the output shaft of the air outlet motor 805. There are multiple air outlet motors 805, and they are evenly distributed on the top of the second fixed bracket 804.

[0023] 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. No further description is given 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 blades 806 and discharges the hot air inside the chassis body 1; 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.

[0024] 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. 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.

[0025] A mounting base 2 is fixedly connected to the inner walls of the right plate 103 and the left plate 105, a slot 3 is provided on the side wall of the mounting base 2, a 6U circuit board 4 is clamped inside the slot 3, a control panel 14 is provided on the front side wall of the front plate 101, a plurality of connecting sockets 15 are provided on the rear side wall of the rear plate 104, and the control panel 14 and the plurality of connecting sockets 15 are all located above the through hole 5, and support legs 13 are fixedly connected to the four bottom corners of the bottom plate 106.

[0026] The first fixed frame 701 and the second fixed 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, and four fastening bolts 10 and four fixing holes 11 are provided on the first fixed frame 701 and the second fixed frame 801.

[0027] from Figure 1 , Figure 2 and Fig.10It can be seen that corresponding threading holes are provided on the right plate 103 and the rotating shaft 6 (the threading holes are relatively small, and the wires will be stuck in the threading holes. The wires will move only under the action of huge external force, effectively preventing the wires from falling off the main board. In addition, dust cannot enter the interior of the chassis body 1). The main purpose is to facilitate the connection of the wires of the air inlet motor 705 and the air outlet motor 805 with the main board inside the chassis body 1. The wires on the air inlet motor 705 are threaded through the threading holes on the right plate 103, and the wires on the air outlet motor 805 are threaded through the threading holes on the rotating shaft 6. In addition, the wires on the air inlet motor 705 and the air outlet motor 805 are long enough and can be fixed to the corresponding connecting rods by binding straps. Symmetrical card slots (not shown in the figure) can also be provided on the corresponding connecting rods to fix the wires. Sufficient length will be reserved for the wires located outside to facilitate telescoping or rotating with the corresponding connecting rods. The rotation angle of the air inlet assembly 7 and the air outlet assembly 8 will not exceed 360 degrees to avoid entanglement of the wires. Working principle: When in use, first adjust the positions of the air inlet 702 and the air outlet 802 according to the placement or installation position of the chassis body 1. First, pull the first connecting rod 708 through the handle 9, and move the first fixing frame 701 out from the inside 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, and then rotates around the rotating shaft 6. After the first fixing frame 701 is rotated to a suitable position, first push the blocking plate 1203 through the toggle rod 1205. The blocking plate 1203 is moved and the blocking plate 1203 is pushed into the interior of the storage slot 1201. When the toggle rod 1205 enters the interior of the concave hole 1206, the blocking plate 1203 completely enters the storage slot 1201. Then, the handle 9 is slowly released. The first fixing frame 701 is fixed to the interior of the through hole 5 under the action of the first spring 7012, thereby 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 802 are adjusted. The air inlet motor 705 blows the external cold air into the interior of the chassis body 1, and dissipates the heat of the 6U circuit board 4 during operation. At the same time, the air outlet motor 805 discharges the heat generated by the 6U circuit board 4, thereby achieving heat dissipation. When the air inlet motor 705, the air inlet fan blades 706, the air outlet motor 805 and the air outlet fan blades 806 need to be repaired or replaced, the first fixing frame 701 is first moved out of the through hole 5 by the handle 9. At this time, the blocking plate 1203 is in the third spring 1204. The through hole 5 is automatically blocked under the action, and then the rotation is carried out around the rotating shaft 6, and the first fixed frame 701 is rotated to a position deviating from the through hole 5. Then the fastening bolt 10 is unscrewed from the inside of the fixing hole 11, and then the first fixed frame 701 is flipped 180 degrees. After that, the air inlet motor 705 and the air inlet fan blades 706 can be repaired or replaced. The repair or replacement of the air outlet motor 805 and the air outlet fan blades 806 is the same as the repair or replacement of the air inlet motor 705 and the air inlet fan blades 706, and will not be repeated here.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
