The remote sensing camera has a severe working environment, and how to reasonably design a power supply control box of the remote sensor plays a crucial role in realizing good electric control quality of the whole remote sensing camera. The traditional electric appliance case of the space remote sensing camera is formed by splicing square boxes, and the mechanical property of the whole remote sensing camera is influenced by the defects of large volume and heavy weight of the structure.
Disclosure of Invention
The invention provides a light high-thermal-conductivity remote sensing camera power supply control box structure aiming at the technical problems of large structure, heavy weight and the like of the existing remote sensing camera.
In order to achieve the above purpose, the invention provides the following technical scheme:
a light high-thermal-conductivity remote sensing camera power supply control box structure comprises a power supply main branch a component, a power supply main branch b component, a power supply backup component and a plurality of circuit board components which are longitudinally arranged, wherein two adjacent components are mutually connected by adopting a labyrinth structure, so that a better electromagnetic shielding function can be realized; the power supply main branch a assembly, the power supply main branch b assembly and the power supply backup assembly respectively comprise a power supply plate frame structure and a power supply module, and the power supply module is directly arranged on the upper surface of the power supply plate frame structure so as to facilitate the heat dissipation of the power supply module; the circuit board assembly comprises a circuit board plate frame structure and a circuit board, wherein the circuit board is directly mounted on the upper surface of the circuit board plate frame structure so as to dissipate heat of the circuit board.
Further, the circuit board assemblies are respectively positioned between the power supply main sub-a assembly and the power supply main sub-b assembly, and the power supply backup assembly is positioned on one side of the power supply main sub-b assembly.
Furthermore, the number of the circuit board assemblies is less than or equal to 10. Generally, less than 10 can completely express the electric function of the power supply control box.
Furthermore, the upper ends of the assemblies are respectively connected through two connecting rods, the lower ends of the assemblies are respectively fixed on the bottom platform through screws, and the two connecting rods are arranged in parallel and respectively horizontally penetrate through the two ends of the upper parts of the assemblies in sequence. The length of the connecting rod depends on the number of the circuit boards.
Furthermore, the diameter phi of the connecting rod is 3 mm-8 mm, and the length L is less than or equal to 500 mm. The ratio of the length L of the connecting rod to the diameter phi of the connecting rod is in a certain range so as to avoid the 'rotating shaft effect' in the assembling process.
Specifically, when the length L of the connecting rod is less than or equal to 60mm, the diameter phi of the connecting rod is 3 mm; when the length of the connecting rod is more than 60mm and less than or equal to 100mm, the diameter phi of the connecting rod is 4 mm; when the length of the connecting rod is more than 100mm and less than or equal to 200mm, the diameter phi is 5 mm; when the length of the connecting rod is more than 200mm and less than or equal to 300mm, the diameter phi is 6 mm; when the length of the connecting rod is more than 300mm and less than or equal to 500mm, the diameter phi is 8 mm.
Furthermore, the distance between the screws is less than or equal to 20mm, so that good electromagnetic shielding and electromagnetic compatibility are realized.
Compared with the prior art, the invention has the beneficial effects that: the traditional power control box is generally divided into two layers: inner sheet frame and outer casing, power module or circuit board are installed on the inner sheet frame, and the inner sheet frame is connected with outer sheet frame through the slide rail again, and the drawback of bringing like this mainly has two: 1. the volume and mass of the whole assembly are too large; 2. the device needing heat dissipation on the circuit board firstly conducts heat to the plate frame, then conducts the heat to the outer shell through the slide way, then conducts the heat to the bottom platform through the outer shell, and finally conducts the heat to the star/machine body through the bottom platform; in the whole process, the inner-layer plate frame and the outer-layer plate frame are mainly contacted through the lug plates at two ends, the contact area is too small, and the sliding rail basically does not play a role in heat conduction, so that the heat conduction efficiency is greatly reduced in the link. The light high-thermal-conductivity remote sensing camera power supply control box structure brings the following benefits: 1. the circuit board and the power supply module are directly arranged on the outer-layer plate frame, so that the weight of the inner-layer plate frame is omitted, and the volume and the mass are greatly reduced. 2. The heat of device directly conducts the frame on power module or the original edition of electric mule, has promoted heat-conduction efficiency greatly, can improve the life of components and parts.
