At this time, the fan module continues to operate, and the fan module drives the air flow inside the shell so that the fan module can quickly dissipate the heat inside the shell to the outside of the shell;

[0005] However, when the fan module is used for a long time, the fan module rotates continuously, so that the air inlet of the fan module will continuously absorb dust, and the dust will continuously accumulate at the mainboard module for a long time;

[0006] Therefore, it is necessary to provide a liquid crystal display heat dissipation module to solve the above problems.

[0007] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0013] A cleaning brush, one end of which is in contact with the heat sink.

[0014] Furthermore, a rear shell is fixedly mounted on the front shell, the interior of the rear shell is fixedly mounted to a fixing block, and the fixing block is aligned with the heat dissipation block.

[0015] Furthermore, a limiting block is fixedly installed on one end of the fixing block close to the heat dissipation block, and a receiving block is inserted into the interior of the limiting block.

[0016] Furthermore, a sealing groove is formed at one end of the mainboard close to the heat dissipation block, and the sealing groove is adapted in shape to one end of the storage block.

[0017] Furthermore, positioning blocks are fixedly mounted on the ends of the fixing blocks, and bolts are connected to the internal threads of the positioning blocks. The bolts are fixedly connected to the front shell through the positioning blocks.

[0018] The beneficial effect of the present application is that a liquid crystal display heat dissipation module provided by the present application can be moved back and forth at a location through a moving rod, so that a cleaning brush can be synchronously moved at the position of the heat dissipation block, so that dust accumulated on the surface of the heat dissipation block can be cleaned by the cleaning brush, thereby avoiding affecting the heat dissipation effect of the heat dissipation block.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] like Figure 1-Figure 2 As shown, the present application provides a liquid crystal display heat dissipation module, including a display screen 1, wherein the display screen 1 is used to display working electronic content and files, and the display screen 1 includes a front shell 11, a mainboard 13 is fixedly installed inside the front shell 11, and a heat dissipation block 14 is fixedly installed on the mainboard 13, wherein the heat dissipation block 14 is used to dissipate heat for parts on the mainboard 13;

[0031] Since the heat sink 14 is used for a long time, dust will be accumulated on the heat sink 14. If the dust cannot be cleaned in time, the heat dissipation effect of the heat sink 14 will be affected, and the normal use of the parts will be affected.

[0032] like Figure 2-Figure 4 As shown, the front shell 11 is fixedly mounted with a rear shell 12, the rear shell 12 is fixedly mounted with a fixed block 15, and a moving groove 18 is provided on the fixed block 15, a moving rod 19 is slidably mounted inside the moving groove 18, and a cleaning brush 20 is fixedly mounted at one end of the moving rod 19, the cleaning brush 20 is in contact with the heat sink 14, so that when the moving rod 19 moves back and forth at the moving groove 18, the cleaning brush 20 will continuously move synchronously at the position of the heat sink 14, so that the dust on the heat sink 14 can be cleaned, and the moving rod 19 is a rectangular structure that is adapted to the moving groove 18, so that when the moving rod 19 moves at the moving groove 18, the cleaning brush 20 can be prevented from shaking;

[0033] Furthermore, the cleaning brush 20 is located at the end of the movable groove 18 and on one side of the heat sink 14 when not in operation, so that the cleaning brush 20 and the movable rod 19 can avoid blocking the movable groove 18, thereby allowing the heat discharged from the heat sink 14 to be discharged through the movable groove 18, and at the same time, the cleaning brush 20 avoids direct contact with the heat sink 14, thereby avoiding affecting the heat dissipation effect of the heat sink 14;

[0034] At the same time, a limiting block 21 is fixedly installed at one end of the fixing block 15 close to the heat sink 14, and a receiving block 22 is inserted into the interior of the limiting block 21. At the same time, a sealing groove 23 is opened at one end of the mainboard 13 close to the heat sink 14, and the sealing groove 23 is adapted to the shape of one end of the receiving block 22. Therefore, when the front shell 11 and the rear shell 12 are installed, after the two are combined, one end of the receiving block 22 will contact the sealing groove 23, so that the outer side of the heat sink 14 can be sealed, and then when the cleaning brush 20 cleans the heat sink 14, the dust dropped at this time will fall on the receiving block 22, so that the dust can be collected by the receiving block 22, and it can be prevented from falling to other positions;

[0035] In addition, a positioning block 16 is fixedly installed at the end of the fixing block 15, and the internal thread of the positioning block 16 is connected to a bolt 17, and the bolt 17 is fixedly connected to the front shell 11 through the positioning block 16. Therefore, after a certain amount of dust is accumulated inside the storage block 22, the bolt 17 can be separated from the front shell 11, so that the fixing block 15 can be removed from the front shell 11, so that the dust accumulated at the storage block 22 can be processed, and the need to disassemble the front shell 11 as a whole is avoided.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
