[0011] As a preferred technical solution of the utility model, there are two contact pads three, and the two fixing plates are respectively fixedly installed on the left and right sides of the rear side of the fixing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1.

[0023] By making the backlight panel 13 contact and fit with the heat conductive sheet 5, the heat generated by the backlight panel 13 during use is transferred to the coolant in the inner cavity of the heat dissipation box 2 through the heat conductive sheet 5, and then the heat in the coolant is transferred to the air for heat dissipation through the heat sink 4, so that the heat is first quickly absorbed by the coolant, thereby preventing the backlight panel 13 from being quickly cooled down when used in an environment with a high temperature, thereby preventing the backlight panel 13 from being unable to be cooled down quickly when the temperature is high, and allowing the backlight panel 13 to be used normally in an environment with a high temperature.

[0024] Wherein, contact pads 1 6 are fixedly installed on both the upper and lower sides of the inner cavity of the installation frame 1, and contact pads 2 7 are fixedly installed on both the left and right sides of the inner cavity of the installation frame 1;

[0025] By means of contact pads 1 6 on the upper and lower sides of the mounting frame 1, the upper and lower sides of the backlight panel 13 are protected, so that the upper and lower sides of the backlight panel 13 will not collide with the mounting frame 1 during use. By means of contact pads 2 7, the left and right sides of the backlight panel 13 can be protected, so that the left and right sides of the backlight panel 13 will not collide with the mounting frame 1 during use.

[0026] Among them, a fixing plate 9 is inserted into the front side of the installation frame 1, and a contact pad 3 10 is fixedly connected to the rear side of the fixing plate 9;

[0027] By inserting the fixing plate 9 on the front side of the mounting frame 1, the fixing plate 9 can be removed, and further, when the backlight source panel 13 is damaged, the backlight source panel 13 can be removed from the inner cavity of the mounting frame 1, thereby eliminating the need to replace the entire mounting frame 1 and the backlight source panel 13. By setting the contact pad three 10, the front side of the backlight source panel 13 is protected by the contact pad three 10, thereby avoiding collision between the fixing plate 9 and the front side of the backlight source panel 13.

[0028] The front side of the heat sink 4 is located in the inner cavity of the heat sink box 2, and the rear side of the heat sink 4 is located outside the heat sink box 2;

[0029] The front side of the heat sink 4 is located in the inner cavity of the heat sink box 2, so that the heat sink 4 can absorb the heat absorbed by the coolant in the inner cavity of the heat sink box 2 and transfer it to the outside of the heat sink box 2, so that the coolant is cooled by the flow of air.

[0030] A slot 8 is provided on the front side of the installation frame 1, and a fixing plate 9 is inserted into the inner cavity of the slot 8;

[0031] By providing the slot 8 , the fixing plate 9 can be inserted into the inner cavity of the slot 8 , and the fixing plate 9 can be disassembled, so that the backlight source plate 13 can be replaced separately.

[0032] Wherein, threaded barrels 11 are fixedly installed on both the left and right sides of the installation frame 1, and the inner cavity of the threaded barrel 11 is threadedly connected with a mounting bolt 12;

[0033] Through the threaded barrels 11 on the left and right sides of the mounting frame 1 , the mounting bolts 12 can be screwed into the inner cavity of the threaded barrel 11 , and then the fixing plate 9 can be fixed by the mounting bolts 12 , and then the backlight source board 13 can be fixed by the fixing plate 9 .

[0034] Wherein, threaded holes are provided on both the left and right sides of the fixing plate 9, and the mounting bolts 12 are threadedly connected to the inner cavity of the threaded holes of the fixing plate 9;

[0035] Through the threaded holes on the left and right sides of the fixing plate 9 , the mounting bolts 12 can be threadedly connected in the threads of the fixing plate 9 , so that the fixing plate 9 can be fixed by the mounting bolts 12 .

[0036] There are two contact pads 3 10, and two fixing plates 9 are fixedly mounted on the left and right sides of the rear side of the fixing plate 9 respectively;

[0037] By providing two contact pads three 10, when the contact pad three 10 contacts the backlight source panel 13, it can contact the left and right sides of the backlight source panel 13, thereby preventing the backlight source panel 13 from being damaged during use.

[0038] The working principle and use process of the utility model are as follows: install the installation frame 1 at a suitable position, and then use the backlight through the backlight panel 13. During use, if the backlight panel 13 is damaged, screw the installation bolts 12 out of the inner cavity of the threaded tube 11, then pull out the fixing plate 9 from the inner cavity of the slot 8, and then put in a new backlight panel 13, then insert the fixing plate 9 into the inner cavity of the slot 8, and then screw the installation bolts 12 into the inner cavity of the threaded tube 11 to fix the fixing plate 9, and contact the backlight panel 13 through the contact pad 3 10 to protect the front side of the backlight panel 13, and contact the backlight panel 13 through the contact pad 1 6 and the contact pad 2 7, so as to protect the up, down, left and right sides of the backlight panel 13;

[0039] Then, the heat conductive sheet 5 contacts the rear side of the backlight panel 13, so that the heat generated during the use of the backlight panel 13 is transferred to the coolant in the inner cavity of the heat dissipation box 2 through the heat conductive sheet 5, and then the heat in the inner cavity of the heat dissipation box 2 is transferred to the air through the heat dissipation sheet 4, thereby dissipating the heat.
