Embodiment 1

[0028] Example 1: Such as figure 1 , Figure 2a , Figure 2b , Figure 5a , Figure 5b , Figure 5c As shown, this embodiment provides a heat dissipation structure of an active phased array antenna, including two symmetrically arranged T / R assemblies 1 and a heat transfer device 2, a part of the heat transfer device 2 is clamped on the The two T / R assemblies 1 are in close contact with the two T / R assemblies 1 . In this embodiment, the heat transfer device 2 is only attached to the heating area 11 of the two T / R assemblies. The two T / R assemblies 1 are fixedly attached to the heat transfer device 2 through bolts; the other part of the heat transfer device 2 is plugged on a cooling plate 3; the heat transfer device 2 is used to The heat generated by the two T / R assemblies 1 is transmitted to the cooling plate 3 .

[0029] In this embodiment, the heat transfer device 2 adopts a vapor chamber; in this embodiment, the vapor chamber is a vacuum phase change vapor chamber, ...

Embodiment 2

[0035] Example 2: In this embodiment, the difference from Embodiment 1 is that the flow channel inlet 332 and the flow channel outlet 333 are located on the same side of the cooling plate.

Embodiment 3

[0036] Example 3: Such as Figure 4As shown, in this embodiment, the difference from Embodiment 1 is that the flow channel 33 is not provided with a flow channel inlet 332 or a flow channel outlet 333, which is only a flow channel body 331 disposed inside the cooling plate body 34 , which is parallel to the upper and lower surfaces of the cooling plate body 34 and surrounds all the slots 31 , so as to cool down the temperature chamber inserted in the slots 31 .

[0037] In this embodiment, the cooling plate directly encapsulates the phase change material in the flow channel body 331 in the cooling plate during production, and the phase change material in the flow channel body 331 is added to the cooling plate itself, whether it is testing or formal use. The T / R assembly is cooled by changing the heat capacity of the material, instead of using an external cooling device to cool the flow channel body in liquid phase or gas phase during the test as in Example 1.

Abstract

The invention relates to the field of active phased array radar equipment, in particular to a heat dissipation structure of an active phased array antenna. The heat dissipation structure of the active phased array antenna comprises two T/R assemblies which are symmetrically arranged and a heat transmitting device, wherein one part of the heat transmitting device is clamped between the T/R assemblies and closely attached to the T/R assemblies, and the other part of the heat transmitting device is connected to a cooling plate in an inserted mode; the heat transmitting device is used for transmitting heat generated by the T/R assemblies to the cooling plate.

Description

technical field [0001] The invention relates to the field of active phased array radar equipment, in particular to a heat dissipation structure of an active phased array antenna. Background technique [0002] There are a large number of highly dense T / R components installed in the active phased array radar antenna. Since the T / R components contain miniaturized microwave integrated circuits, they will generate a lot of heat during operation, making the temperature of the module itself sharp High temperature will undoubtedly affect the performance and service life of the phased array radar antenna itself. Therefore, the heat dissipation design is becoming increasingly important in the active phased array antenna. Contents of the invention [0003] The purpose of the present invention is to overcome the problem of difficult heat dissipation of the phased array antenna T / R assembly in the prior art. A heat dissipation structure of an active phased array antenna with high heat...
