[0025] Please see Figure 1 , Figure 2 and Figure 3 A phased array antenna with a heat dissipation mechanism includes a phased array antenna body 1 and a heat dissipation frame 2.

[0026] The front side of the heat dissipation frame 2 is connected to the phased array antenna body 1 by bolts in an existing detachable manner.

[0027] A mounting frame 210 is attached to the inner side of the heat dissipation frame 2. A VC heat spreader 220 is installed on the mounting frame 210 by bolts. Connecting posts 230 are fixedly connected to the four corners of the side of the mounting frame 210. A copper plate 250 is provided on the side of the mounting frame 210. Connecting holes 240 are opened at the four corners of the copper plate 250. The connecting posts 230 are inserted into the connecting holes 240. Heat dissipation teeth 260 are evenly arranged on the other side surface of the copper plate 250. Heat dissipation channels 270 are provided between adjacent heat dissipation teeth 260. The back side of the heat dissipation frame 2 has slots 280 on the top and bottom. A cooling fan 290 is installed inside the slots 280. The cooling fan 290 is located on one side of the heat dissipation teeth 260, facing the copper plate 250.

[0028] During heat dissipation, the side of the VC heat dissipation plate 220 is attached to the side of the phased array antenna body 1 to absorb heat from the phased array antenna body 1. Excess heat is absorbed by the copper plate 250. At this time, the cooling fan 290 works, and the generated airflow acts on the side of the copper plate 250 connected with the heat dissipation teeth 260. Since the heat dissipation teeth 260 are evenly arranged on the side of the copper plate 250, a heat dissipation channel 270 is formed. The generated airflow acts within the heat dissipation channel 270 and flows to both sides, thereby dissipating heat from the phased array antenna body 1.

[0029] Meanwhile, the components are connected in a detachable manner, which facilitates subsequent maintenance of the whole system and ensures the normal use of the phased array antenna body 1.

[0030] As a preferred technical solution of this utility model, side grooves 3 are provided on both sides of the heat dissipation frame 2, and heat dissipation filter plates 310 are installed inside the side grooves 3.

[0031] The airflow to both sides is discharged through two sets of heat dissipation filters 310, which, combined with the above, achieves the effect of heat dissipation for the main body 1 of the phased array antenna.

[0032] As a preferred technical solution of this utility model, four sets of VC heat dissipation plates 220 are provided, and the four sets of VC heat dissipation plates 220 are arranged in a square on the mounting frame 210, with the side of the VC heat dissipation plate 220 attached to the side of the phased array antenna body 1.

[0033] As a preferred technical solution of this utility model, a filter plate is fixedly connected to the inner wall of the outer side of the groove 280.
