Description

Technical Field

[0001] The utility model relates to the technical field of satellite antenna heat dissipation bases, in particular to a phased array satellite antenna enhanced heat dissipation base. Background Art

[0002] In recent years, vehicle-mounted tracking control systems using phased array satellite antennas have been increasingly widely used. In activities such as large-scale event news interviews, disaster relief and rescue site reports, and anti-terrorism scenes, vehicle-mounted phased array satellite antennas are favored for their small size, low cost, intelligence, high reliability, and simple maintenance. The phased array satellite antenna system consists of T / R components, a wave control sub-unit, a power supply sub-unit, an antenna unit array, a feeding system, a structure and an environmental control system, etc. The phased array satellite antenna system has a large number of components and a high integration level. Phased array satellite antenna technology has developed rapidly in China in recent years. This antenna is composed of many phased antenna sub-arrays, has a relatively low profile, and most of its antennas are composed of electronic components, with light weight and is suitable for large-scale production. Combined with the use of a strap-down inertial navigation / GPS antenna control system to automatically capture satellites, the pointing accuracy is very high. Phased array satellite antennas usually have two modes. A more common one is that the reception and transmission are designed on the same board, with some array elements for reception and some for transmission.

[0003] In the prior art, the traditional heat dissipation method is to use the method of ventilation on both sides for cooling. However, in hot summer weather, when it is used in the external environment, when using the natural ventilation method, the heat dissipation effect will be severely reduced when the external environment temperature is relatively high. Therefore, the utility model proposes a phased array satellite antenna enhanced heat dissipation base to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a phased array satellite antenna enhanced heat dissipation base.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A phased array satellite antenna enhanced heat dissipation base, including an installation box, the upper end of the installation box is fixedly connected with a fixed air duct, the upper end of the installation box is slidably connected with a movable air duct that cooperates with the fixed air duct. Both the fixed air duct and the movable air duct are of a hollow design. One end of the movable air duct is slidably connected inside the fixed air duct. A cavity is opened inside the installation box, and a semiconductor refrigeration component is fixedly connected through the inner walls of the cavity and the fixed air duct. A fixed air duct side opening is opened on the side wall of the fixed air duct, and a movable air duct side opening is opened on the side wall of the movable air duct. The movable air duct side opening is opposite to the fixed air duct side opening.

[0007] Preferably, circulation fans are installed in both the fixed air duct and the movable air duct, and the blowing directions of the two circulation fans are opposite.

[0008] Preferably, air inlets and air outlets are respectively formed on the side walls at both ends of the installation box.

[0009] Preferably, both the air inlet and the air outlet are communicated with the cavity, and a heat dissipation fan is installed in the cavity.

[0010] Preferably, a power supply is installed inside the installation box.

[0011] Preferably, a threaded rod is rotatably connected to the inner wall of the fixed air duct, a nut is fixedly embedded on the side wall of the movable air duct, and the threaded rod passes through the nut and is threadedly connected thereto.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By providing a fixed air duct, a movable air duct and a semiconductor refrigeration component, during heat dissipation, the semiconductor refrigeration component cools the air in the fixed air duct and the movable air duct. After passing through the two circulation fans, the cold air circulates between the side opening of the fixed air duct and the side opening of the movable air duct. At the same time, the heat dissipation fan, the air inlet and the air outlet are used to cool the semiconductor refrigeration component, so as to dissipate heat from the phased array satellite antenna between the fixed air duct and the movable air duct. By means of forced refrigeration, heat dissipation of the phased array satellite antenna body in a high-temperature environment is realized, and the heat dissipation effect can be greatly improved.

[0014] 2. By providing a threaded rod and a nut, the phased array satellite antenna is placed between the fixed air duct and the movable air duct. The threaded rod is rotated to drive the nut threadedly connected thereto to move, thereby driving the movable air duct to move, adjusting the distance between the movable air duct and the fixed air duct, so as to improve the installation stability. At the same time, phased array satellite antennas of different sizes can be installed and fixed. BRIEF DESCRIPTION OF THE DRAWINGS
