[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, this embodiment provides a dual-receive dual-transmit Ku-band phased array antenna heat dissipation mechanism, including a front bracket 1, a left bracket 2, a right bracket 3, a rear bracket 4, a heat dissipation mounting plate 5, a heat dissipation fan 6, a dual receiving array surface 7, a dual transmitting array surface 8, a control box 9, and a radome 10.

[0033] Among them, the dual transmitting array 8 is used to transmit signals, and the dual receiving array 7 is used to receive signals; the control box 9 is connected to the dual receiving array 7 and the dual transmitting array 8 respectively to control the dual transmitting array 8 to transmit signals and the dual receiving array 7 to receive signals, and convert the signals received by the dual receiving array 7 into the target format.

[0034] like Figure 4As shown, the two surfaces of the heat dissipation mounting plate 5 are the mounting surface and the heat dissipation surface respectively, and the dual receiving array 7 and the dual transmitting array 8 are installed on the mounting surface of the heat dissipation mounting plate 5 by bolts; there are 4 dual receiving arrays 7 and dual transmitting arrays 8 in total. The heat dissipation surface of the heat dissipation mounting plate 5 is provided with a plurality of mutually parallel heat dissipation teeth. Four heat dissipation fans 6 and a control box 9 are installed on the heat dissipation surface of the heat dissipation mounting plate 5. The control box 9 is installed in the middle of the heat dissipation surface of the heat dissipation mounting plate 5, and the dual receiving array 7 and the dual transmitting array 8 are installed on the mounting surface of the heat dissipation mounting plate 5 with the length direction passing through the center of the control box 9 as the center line, so that the connecting line of the control box 9 passes through the mounting hole of the heat dissipation mounting plate 5, and is convenient to connect with the dual receiving array 7 and the dual transmitting array 8. Each heat dissipation fan 6 corresponds to the dual receiving array 7 or the dual transmitting array 8 one by one. The blowing direction of the heat dissipation fan 6 is perpendicular to the heat dissipation surface of the heat dissipation mounting plate 5 and is directly opposite to the heat dissipation surface of the heat dissipation mounting plate 5. The heat dissipation mounting plate 5 is not provided with heat dissipation teeth at the position where the heat dissipation fan 6 and the control box 9 are installed.

[0035] like Figure 2 and Figure 3 As shown, the front bracket 1, the left bracket 2, the rear bracket 4 and the right bracket 3 are sequentially mounted to four adjacent edges of the heat dissipation surface of the heat dissipation mounting plate 5, and the front bracket 1 and the rear bracket 4 are connected with the left bracket 2 and the right bracket 3 by bolts. The rear bracket 4 and the right bracket 3 are perpendicular to the direction of the heat dissipation teeth on the heat dissipation surface of the heat dissipation mounting plate 5.

[0036] Ventilation holes are processed on the front bracket 1, the left bracket 2, the right bracket 3, and the rear bracket 4. A groove is opened at one end of the front bracket 1, the left bracket 2, the right bracket 3, and the rear bracket 4 away from the heat dissipation mounting plate 5. When the front bracket 1, the left bracket 2, the right bracket 3, and the rear bracket 4 are connected to the mounting plane, the groove position forms a ventilation slot with the mounting plane.

[0037] When the cooling fan 6 sucks air, the wind enters from the ventilation holes and ventilation slots, and most of the wind enters from the ventilation slots; the cooling fan 6 blows out air directly toward the heat dissipation surface of the heat dissipation mounting plate 5, and the blown wind takes away the heat on the heat dissipation mounting plate 5 to form hot air, most of the hot air is blown out from between the heat dissipation teeth parallel to each other, and finally blown out from the ventilation holes on the left bracket 2 and the right bracket 3, and some hot air will also be blown out from other ventilation holes.

[0038] A heat-conducting medium is coated between the dual receiving array 7, the dual transmitting array 8 and the heat dissipation mounting plate 5; a sealing ring is provided between the dual receiving array 7, the dual transmitting array 8 and the heat dissipation mounting plate 5 to ensure that the dual receiving array 7 and the heat dissipation mounting plate 5, as well as the dual transmitting array 8 and the heat dissipation mounting plate 5 are sealed to prevent water vapor in the external environment from entering the space between the antenna cover 10 and the heat dissipation mounting plate 5.

[0039] A sealing ring is provided between the control box 9 and the heat dissipation mounting plate 5 to seal the mounting surface between the control box 9 and the heat dissipation mounting plate 5 to prevent water vapor in the external environment from entering the space between the antenna cover 10 and the heat dissipation mounting plate 5 and entering the control box 9; heat dissipation teeth are processed on the outer side of the control box 9, and the control box 9 and the heat dissipation mounting plate 5 are installed separately, and combined with the relative installation positions of the control box 9 and the dual receiving array 7 and the dual transmitting array 8 on the two surfaces of the heat dissipation mounting plate 5, the heat generated by the control box 9 is almost not transmitted to the heat dissipation mounting plate 5, but is self-dissipated through its own heat dissipation teeth, ensuring that the dual receiving array 7 and the dual transmitting array 8 are relatively evenly dissipated through the heat dissipation mounting plate 5 and are not affected by the heat dissipation of the control box 9.

[0040] like Figure 5 As shown, the antenna cover 10 is covered on the outside of the dual receiving array 7 and the dual transmitting array 8, and the antenna cover 10 is installed on the heat dissipation mounting plate 5. A sealing ring is provided between the antenna cover 10 and the heat dissipation mounting plate 5 to prevent water vapor in the external environment from entering the space between the antenna cover 10 and the heat dissipation mounting plate 5.

[0041] Ventilation holes are processed on the front bracket, left bracket, right bracket and rear bracket to improve the heat circulation under the heat dissipation mounting plate. A sealing ring is provided between the control box 9 and the heat dissipation mounting plate 5, a sealing ring is provided between the dual receiving array 7, the dual transmitting array 8 and the heat dissipation mounting plate 5, and a sealing ring is provided between the antenna cover 10 and the heat dissipation mounting plate 5, which are used to seal waterproof and dustproof to meet environmental adaptability. Heat dissipation teeth are processed on the outside of the control box 9, and a heat conductive medium is coated between the dual receiving array, the dual transmitting array and the heat dissipation mounting plate 5 to better transfer the heat generated by the dual receiving array and the dual transmitting array to the heat dissipation teeth, thereby reducing the heat loss of the internal components of the antenna and improving the reliability of the antenna. A heat dissipation fan is installed, and ventilation holes are processed on the bracket to facilitate the dredging of the heat gathered around the heat dissipation teeth. It has a simple structure, is easy to install, easy to replace, easy to maintain, and has a certain degree of portability.
