It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The application provides an active phased array radar radio frequency front end.
As shown in fig. 1, in an embodiment of the present application, an active phased array radar radio frequency front end includes a heat controlling case 100, an antenna control board 200, a power board 300, a feeding board 400, a signal transceiving board 500, a radio frequency board 600, and a thermostat 700.
The heat control housing 100 includes a flow passage 110, and the flow passage 110 is disposed on an inner surface of the heat control housing 100.
The antenna control board 200 is disposed at a first end of the inner cavity of the heat control housing 100, and the antenna control board 200 is tightly attached to the inner cavity of the heat control housing 100.
The power panel 300 is disposed between the antenna control board 200 and the second end of the inner cavity of the heat control housing 100.
The power board 400 is disposed between the power board 300 and the second end of the inner cavity of the heat control housing 100.
The signal transceiver board 500 is disposed between the feeding board 400 and the second end of the inner cavity of the heat control housing 100.
The radio frequency board 600 is disposed at the second end of the inner cavity of the heat control shell 100, and the radio frequency board 600 is tightly attached to the inner cavity of the heat control shell 100.
The temperature regulator 700 is disposed near a first end of the inner cavity of the heat control housing 100 and is in communication with the flow passage 110.
Specifically, the antenna control board 200, the power supply board 300, the power feeding board 400, the signal transceiver board 500, and the radio frequency board 600 are accommodated by the heat control case 100. The antenna control board 200, the power board 300, the power board 400, the signal transceiver board 500 and the radio frequency board 600, which generate waste heat, are enclosed inside the heat control case 100 by using the antenna control board 200 and the radio frequency board 600, and most of the waste heat is diffused outward in a heat radiation manner by using the vacuum environment inside the heat control case 100.
It should be noted that the heat control housing 100 is closely attached to the power panel 300, the power feeding panel 400, the signal transceiver panel 500, and the radio frequency panel 600, and the heat control housing 100 also transfers waste heat through a heat transfer manner.
The embodiment relates to an active phased array radar radio frequency front end, because the inner surface of the heat control shell 100 is provided with a runner 110, when heat radiation contacts a metal layer of the runner 110, heat exchange is carried out with the metal layer, waste heat absorption in the heat control shell is realized, specifically, a heat exchange medium is arranged in the runner 110, the heat exchange medium is transferred by the temperature regulator 700, waste heat transfer is realized, and the service life of the radio frequency front end is ensured to reach a preset service life. The problem that the element of the radio frequency front end is high in integration level and small in size and is difficult to dissipate heat in time is effectively solved, and the service life of the radio frequency front end is prolonged.
As shown in fig. 2, in an embodiment of the present application, the heat control housing 100 further includes a first sealing ring 121 and a second sealing ring 122. The first sealing ring 121 is disposed between the inner wall of the heat control housing 100 and the antenna control board 200. The second sealing ring 122 is disposed on the inner wall of the heat control housing 100, and the second sealing ring 122 is disposed near the rf plate 600. The space between the first sealing ring 121 and the second sealing ring 122 is vacuum.
Specifically, the first sealing ring 121 is disposed between the inner wall of the heat control housing 100 and the antenna control board 200. This is because the waste heat generation amount of the antenna control board 200 is relatively low, and the first sealing ring 121 expands after receiving heat transferred, enhancing the sealability of the first sealing ring 121.
It should be noted that the second sealing ring 122 is disposed on the inner wall of the heat control housing 100, and the second sealing ring 122 is disposed near the rf plate 600. The amount of waste heat generated from the rf board 600 is large, and one sidewall of the rf board 600 is exposed to air, and the transfer of waste heat partially depends on thermal convection of air, which has low heat dissipation efficiency. The rf board 600 needs to closely conform to the heat management housing 100 to enhance heat transfer from the waste heat.
This embodiment relates to a seal ring. The first seal ring 121 is advantageous in enhancing sealability. The second sealing ring 122 is disposed near the rf plate 600 to improve the waste heat transfer efficiency of the rf plate 600.

The distance between the first boss 131 and the second boss 132 is equal to the distance between the third contact edge 213 and the fourth contact edge 214.
The present embodiment relates to a heat controlling case 100. In order to take into consideration the straight edge design of the arc plate 210, the heat controlling case 100 is provided with a first protrusion 131 and a second protrusion 132. The first protruding portion 131 and the second protruding portion 132 clamp the arc plate 210, prevent the displacement of the arc plate 210, further achieve the connection stability of the arc plate 210, reduce the displacement of the arc plate 210, prevent the arc plate 210 from not contacting the heat control shell 100, and improve the heat transfer efficiency.
As shown in fig. 2 and 3, in an embodiment of the present application, the third contact edge 213 abuts against the first protrusion 131. The fourth contact edge 214 abuts the second boss 132.

The present embodiment relates to a heat dissipation structure of a contact side. In order to ensure the heat transfer efficiency of the third contact edge 213 and the fourth contact edge 214, the first heat dissipation path 111 is disposed in the first protrusion 131 and the second protrusion 132, and the first heat dissipation path 111 can ensure the temperature difference between the contact edge and the protrusion, thereby achieving good heat transfer.
As shown in fig. 2 and 3, in an embodiment of the present application, the flow channel 110 includes a first heat dissipation channel 111.
