[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figures 1 to 4 In the utility model: a multi-layer impedance board that is easy to dissipate heat, includes a main body 1, a mounting box 2 is arranged below the main body 1, the inner side of the mounting box 2 is fixedly connected to the main body 1, a square cavity 3 is opened inside the mounting box 2, two fans 4 are embedded in the inner wall of the square cavity 3, the bottoms of the two fans 4 both penetrate and extend to the bottom of the mounting box 2, two groups of heat dissipation channels 5 arranged at equal distances are opened on the inner wall of the square cavity 3, and air outlet grooves 6 are opened on the left and right sides of the mounting box 2.

[0025] In the utility model, when in use, the user turns on the fan 4, the fan 4 will draw air into the square cavity 3, and the air will then be discharged from the two groups of heat dissipation channels 5 to the air outlet grooves 6 and discharged from the air outlet grooves 6. During the process, the heat of the main body 1 will be transferred to the installation box 2, and the air flowing in the heat dissipation channels 5 will take away the heat transferred from the main body 1 to the installation box 2, thereby achieving the effect of heat dissipation for the main body 1.

[0026] See also Figure 2 , wherein: the inner wall of the air outlet groove 6 is slidably connected with an adjusting block 7 arranged at an equal distance, the inner wall of the air outlet groove 6 is provided with two slide grooves 8, a locking plate 9 is arranged between the two slide grooves 8, the front and back sides of the locking plate 9 are slidably connected with the inner walls of the two slide grooves 8 respectively, the inner walls of the two slide grooves 8 are fixedly connected with springs 10, and the other ends of the two springs 10 are fixedly connected with the locking plate 9.

[0027] In the utility model, during use, the heat dissipation channel 5 can be closed or the size of the exhaust port of the heat dissipation channel 5 can be reduced by sliding the adjustment block 7. After the exhaust port of the heat dissipation channel 5 is reduced, the air discharged from the heat dissipation channel 5 will become less, and the air flow in other heat dissipation channels 5 whose exhaust port sizes have not been changed will increase. Through this feature, the user can appropriately reduce the size of the exhaust port of the heat dissipation channel 5 where the heat generation area is smaller, thereby increasing the air flow in the heat dissipation channel 5 where the other heat generation area is larger, thereby achieving the purpose of improving the heat dissipation effect of the larger heat dissipation area, reasonably dissipating the heat dissipation effect, and improving the quality of heat dissipation of the main body 1.

[0028] See also Figures 2 to 4 , wherein: a pull block 11 is fixedly connected to one side of the locking plate 9 away from the body 1 , and a surface of the pull block 11 is provided with anti-slip grooves.

[0029] In the utility model, the elastic force of the spring 10 pushes the locking plate 9 to lock the position of the adjustment block 7. The user can pull the locking plate 9 through the pull block 11 to facilitate the user to adjust the position of the adjustment block 7, thereby improving the practicality of the device.

[0030] See also Figure 2 and 4 , wherein: an adjusting plate 12 is fixedly connected to the left side of the adjusting block 7 , and the bottom of the adjusting plate 12 is slidably connected to the inner wall of the air outlet groove 6 .

[0031] In the present invention, the setting of the adjustment plate 12 can facilitate the user to adjust the position of the adjustment block 7, thereby improving the practicability of the device.

[0032] See also Figure 2 , wherein: a filter plate 13 is fixedly connected to the bottom of the installation box 2, and the top of the filter plate 13 is in contact with the two fans 4 respectively.

[0033] In the present invention, the filter plate 13 can filter the dust in the air, thereby preventing the dust from entering the interior of the device and causing pollution, thereby improving the practicability of the device.
