Description

Technical Field

[0001] The present invention relates to the technical field of phased array antennas, and in particular to a spherical phased array antenna high-efficiency heat dissipation component and a spherical phased array antenna. Background Art

[0002] Spherical phased array antennas can achieve full-range scanning coverage of the airspace, which has an incomparable advantage over the 120° airspace scanning coverage of planar phased array antennas in phased array antenna systems. They can be used in fixed, vehicle-mounted, airborne, and ship-mounted communication systems, and have strong platform adaptability. However, they are all used in unobstructed outdoor environments, so the products are also exposed to wind and sun all year round, with high ambient temperatures. At the same time, there are also heat-generating power devices inside, which can easily cause component damage due to the inability to dissipate heat in time.

[0003] The currently disclosed heat dissipation forms are heat dissipation through heat dissipation holes, or heat dissipation through water pipes and heat conduction pipes combined with heat box-type air cooling. The heat dissipation efficiency of the heat dissipation hole form is low, and it cannot meet the heat dissipation requirements of the spherical array antenna. In addition, since the spherical array antenna is exposed to the outside all year round in an unshaded outdoor environment, in some severe weather such as wind and rain, the spherical array antenna lacks a protective structure, so it is very easy to cause damage to the antenna array, and then cause the device to be damaged and unusable. The heat dissipation form of the water pipe, heat conduction pipe and heat box-type air cooling is complex in structure and requires manual maintenance according to weather and usage requirements. The operation is cumbersome, and it greatly increases the production cost, and the product competitiveness is low. Therefore, high efficiency, low cost, easy operation, and easy maintenance have become key technologies that need to be urgently solved in the heat dissipation design of spherical phased array antenna products.

[0006] It also includes a fan dust cover, which covers the thermal control fan at the inlet and outlet of the heat dissipation duct and is installed in the outer ring of the structure formed by splicing the upper thermal control plate, the right support arm, the bottom thermal control plate, and the left thermal control support arm.

[0007] The heat dissipation teeth of the upper thermal control plate, the bottom thermal control plate, and the left thermal control support arm are in the same direction.

The upper thermal control plate, the right support arm, the bottom thermal control plate, and the left thermal control support arm are provided with sealing grooves for installing sealing strips at the splicing. The right support arm is an arc-shaped cavity structure.

[0008] Utilizing the above-mentioned high-efficiency heat dissipation component, an antenna cover and a spherical antenna array are respectively installed on the inner and outer circular flanges on the upper surface of the heat dissipation component. The antenna cover covers the spherical antenna array inside. The inner ring flange at the bottom of the heat dissipation component is connected to the base through an inner ring lug, and a sealing groove for installing a sealing strip is provided between the high-efficiency heat dissipation component and the antenna cover and the base.

[0009] Compared with the prior art, the present invention has the following advantages: the present invention efficiently solves the heat dissipation requirements of each module installed on the upper thermal control plate, the bottom thermal control plate, and the left thermal control support arm, greatly shortens the production cycle of the whole machine and reduces the production cost.
