Problems solved by technology
[0004] The present invention aims at the problems existing in the above-mentioned prior art, and proposes a liquid-cooled sub-box suitable for radar antennas. In view of the fact that the radar antenna itself uses liquid cooling to dissipate heat, a cooling liquid flow channel is provided, and the sub-box is designed as a liquid In the cold form, the heat can be taken away by the flow channel of the radar antenna system itself, which solves the problem that the existing radar antenna system cannot effectively dissipate heat

Embodiment Construction
[0025] The embodiments of the present invention will be described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention. Detailed implementation modes and specific operation procedures are given, but the protection scope of the present invention is not limited to the following implementations. example.
[0026] Such as Figure 1-5 As shown, the liquid-cooled plug-in box suitable for radar antennas provided by the present invention includes a left cold plate 1, a right cold plate 2, a lower cold plate 3, an upper side plate 4, and a rear side plate 5. In this embodiment The left side cold plate 1, the right side cold plate 2, the lower cold plate 3, the upper side plate 4 and the rear side plate 5 are fixed and spliced by screws to form the main frame structure of the liquid-cooled plug-in box. The front of the liquid-cooled plug-in box is spliced by plug-ins. To form a sealed plug-in box. The plug-in box is designe...

The invention discloses a liquid-cooled sub-box suitable for radar antennas, which comprises a left cold plate, a right cold plate, a lower cold plate, an upper side plate, a rear side plate, a left cold plate, a right cold plate and The cooling fluid passages of the lower cold plate each have two openings; wherein: one of the openings of the left cold plate and one of the openings of the right cold plate are used as openings communicating with the external cooling liquid, respectively connected to the radar antenna system. The cooling liquid passages are connected; the two openings of the lower cold plate communicate with the other opening of the left cold plate and the other opening of the right cold plate respectively. The liquid-cooled sub-box suitable for radar antennas provided by the present invention is designed in a liquid-cooled form, and has the characteristics of efficient heat dissipation, compact structure, and flexible configuration.
Description
Technical field [0001] The invention relates to the technical field of radar antennas, in particular to a liquid-cooled plug-in box suitable for radar antennas. Background technique [0002] The internal space of the radar antenna system structure is small, the power supply requirements are high, and the matching power distribution combination structure is compact in size and high in heat flow density. The power distribution board in the power distribution combination generally adopts the form of plug-in. The main power plug-in has a large heating power, and the heating module is small in size and has a large heat flow density. [0003] Nowadays, most plug-in boxes use air-cooled form to dissipate heat. The disadvantage is that the noise is large, and the air duct cannot be sealed, resulting in poor electromagnetic shielding effect, because the existence of the air duct causes dust deposition to damage the plug-in and its electronic devices and cannot be achieved. Dustproof requir...
