[0020] An air-conditioning circuit board that is easy to install comprises a base plate 1 and an air-conditioning circuit board body 2. A protective mechanism is arranged on the top of the base plate 1.

[0021] In this embodiment, the protection mechanism includes four connecting seats 3 fixedly connected to the base plate 1, and a threaded hole 301 is opened inside the connecting seat 3. The air-conditioning circuit board body 2 is threadedly connected with four fixed threaded rods 201 through the protruding mounting portion. The fixed threaded rods 201 are threadedly connected to the threaded holes 301, which is convenient for the installation and fixation of the air-conditioning circuit board body 2, and convenient for the user to loosen the fixed threaded rods 201 to disassemble the air-conditioning circuit board body 2, which is beneficial for the user to inspect and repair the air-conditioning circuit board body 2. A heat sink group 4 is fixedly installed on the top of the base plate 1, and a thermal conductive adhesive 5 is provided on the top of the heat sink group 4. The size of the thermal conductive adhesive 5 is adapted to the heat sink group 4, and the thermal conductive adhesive 5 is tightly fitted to the bottom of the air-conditioning circuit board body 2. The heat generated by the air-conditioning circuit board body 2 during work is conducted to the heat sink group 4 through the thermal conductive adhesive 5, and the heat dissipation is accelerated through the heat sink group 4, thereby enhancing the protection of the electronic components on the air-conditioning circuit board body 2.

[0022] Among them, the front and back sides of the base plate 1 are fixedly connected with a filter screen 6, the inside of the base plate 1 is fixedly connected with a heat dissipation fan 7, the bottom of the base plate 1 is provided with a heat dissipation hole 8, the inside of the base plate 1 is provided with a mounting groove 101, the heat dissipation fan 7 is located inside the mounting groove 101, and the heat dissipation fan 7 is powered on and rotates to discharge the air at the bottom of the heat sink group 4 through the heat dissipation hole 8. At the same time, the air outside the base plate 1 flows into the space at the bottom of the heat sink group 4 through the filter screen 6, thereby improving the fluidity of the air in the space at the bottom of the heat sink group 4 and facilitating the heat dissipation of the heat sink group 4. A mounting frame 9 is fixedly connected to the top of the base plate 1.

[0023] In addition, an electrostatic eliminator 10 is fixedly connected to the bottom of the mounting frame 9. The mounting frame 9 is an inverted U-shaped structure.

The electrostatic eliminator 10 generates corona discharge through a high-voltage power generator and a discharge electrode, ionizes the air into a large number of positive and negative ions, and then uses wind to blow these positive and negative ions to the surface of the object to neutralize static electricity, or directly brings the electrostatic eliminator 10 close to the surface of the object to neutralize static electricity, reduce the impact of static electricity on the air-conditioning circuit board body 2, and increase the stability of the air-conditioning circuit board body 2 during use. A plurality of mounting holes 11 are opened on the base plate 1, and the number of mounting holes 11 is four. The four mounting holes 11 are symmetrically distributed. The user fixes the screw through the mounting hole 11 to penetrate the base plate 1, and uses the fixing screw to install and fix the base plate 1, thereby completing the installation of the air-conditioning circuit board body 2.

[0024] The working principle of the utility model is:

[0025] During the use of the air-conditioning circuit board, the user fixes the screw through the base plate 1 through the mounting hole 11, and uses the fixing screw to install and fix the base plate 1, thereby completing the installation of the air-conditioning circuit board body 2. When the air-conditioning circuit board body 2 is working, the heat generated by the air-conditioning circuit board body 2 during work is conducted to the heat sink group 4 through the thermal conductive adhesive 5, and the heat dissipation is accelerated through the heat sink group 4. At the same time, the heat dissipation fan 7 is powered on and rotates, and the air at the bottom of the heat sink group 4 is discharged through the heat dissipation hole 8. The air outside the base plate 1 flows into the space at the bottom of the heat sink group 4 through the filter 6, thereby improving the fluidity of the air in the space at the bottom of the heat sink group 4, facilitating the heat dissipation of the heat sink group 4, and the static eliminator 10 is powered on to reduce the influence of static electricity on the electronic components on the air-conditioning circuit board body 2, thereby achieving the purpose of heat dissipation and anti-static of the air-conditioning circuit board and increasing the working stability of the air-conditioning circuit board.
