Technical Field
[0001] This utility model relates to the field of satellite communication technology, specifically a dual-mode satellite data link terminal. Background Technology
[0002] A dual-mode satellite data link terminal is a terminal device that supports two different satellite communication modes, primarily used for data transmission, navigation and positioning, and beyond-line-of-sight communication in military or civilian fields. Its core feature is the integration of the technological advantages of different satellite systems to meet multifunctional needs in complex environments.
[0003] For example, Chinese patent CN214480614U discloses a dual-mode satellite data link end-machine structure. The signal processor is connected to the upper end of the power amplifier. One end of the signal processor is connected to a Beidou satellite receiving port and a relay satellite receiving port. One side wall of the signal processor is provided with an opening slot for installing a side door. The two side walls of the opening slot are respectively provided with sliding devices. One end of the sliding device is connected to a stabilizing device. A mounting plate is connected between the two sliding devices. Several sets of miniature cooling fans are installed at equal intervals on the mounting plate. Several sets of through holes are provided at equal intervals on the mounting plate.

The communication circuit board 10201 and the power circuit board 10202 are respectively disposed on both sides of the heat absorption plate 10301. The communication circuit board 10201 and the power circuit board 10202 are respectively disposed on both sides of the heat absorption plate 10301, so that the heat absorption plate 10301 can absorb the heat generated by the communication circuit board 10201 and the power circuit board 10202 during operation. Heat dissipation plates 10302 are fixedly installed at both ends of the heat absorption plate 10301, so that the heat dissipation plates 10302 can dissipate the heat absorbed by the heat absorption plate 10301. The outer casing assembly 101 includes a first outer casing 10101 and a second outer casing 10102. Both the first outer casing 10101 and the second outer casing 10102 are C-shaped structures. Both the second outer shell 10102 and the first outer shell 10101 have a C-shaped structure, which facilitates the combination of the first outer shell 10101 and the second outer shell 10102 to form a sealed cavity.

[0037] The first outer shell 10101 is provided with a screw seat 10103 at one end, and the second outer shell 10102 is provided with a fixing screw 10112 on the outer side of one end. The fixing screw 10112 is threadedly connected to the screw seat 10103. The threaded connection between the fixing screw 10112 and the screw seat 10103 facilitates the fixed connection between the first outer shell 10101 and the second outer shell 10102.
[0038] The heat absorber plate 10301 has reinforcing grooves 10304 at both the top and bottom. A reinforcing strip 10105 is fixedly installed inside the first outer shell 10101. The reinforcing strip 10105 is set inside the reinforcing groove 10304. The installation stability of the heat absorber plate 10301 is improved by setting the reinforcing strip 10105.
[0039] The reinforcing strip 10105 and the reinforcing groove 10304 are both provided with through holes 10305, and the communication circuit board 10201 and the power circuit board 10202 are electrically connected. The through holes 10305 facilitate the electrical connection between the communication circuit board 10201 and the power circuit board 10202.
[0040] The communication circuit board 10201 has a communication module 10203 fixedly installed on its top. One end of the communication module 10203 is provided with a communication interface 10204.

Heat dissipation plates 10302 are fixedly installed at both ends of the heat absorption plate 10301, allowing the heat dissipation plates 10302 to dissipate the heat absorbed by the heat absorption plate 10301. Since both the first outer shell 10101 and the second outer shell 10102 are C-shaped, they can be combined to form a sealed cavity, providing sealing protection for the internal communication component 102 and preventing dust from entering and affecting it. 02. In operation, the through-slot 10106 facilitates the placement of the heat sink 10302 on the outside of the cavity formed by the first housing 10101 and the second housing 10102. The phase change liquid and capillary layer 10306 facilitate the absorption of heat and vaporization of the liquid phase change liquid within the heat absorber 10301, which then flows into the heat sink 10302. The phase change liquid gas inside the heat sink 10302 dissipates heat and liquefies, then is drawn into the heat absorber 10301 by the capillary action of the capillary layer 10306, achieving efficient heat dissipation from the interior of the housing assembly 101.
