Description

Technical Field

[0002] Airborne LiDAR is a remote sensing device mounted on an aircraft, used to acquire three-dimensional point cloud data of the Earth's surface from the air. Because it generates significant heat during operation, heat dissipation is crucial to ensuring stable operation. Improper heat dissipation can lead to performance degradation, increased failure rates, reduced data quality, and reduced operating time.

[0003] Traditional airborne lidars are mainly equipped with many internal heat-conducting plates connected to component mounting bases to quickly transfer the heat from the heating elements to the metal casing. However, in order to reduce wind resistance, keep the equipment appearance smooth and beautiful, and avoid scratches on personnel, it is generally not possible to add external cooling fins. Therefore, the heat dissipation effect of this structure is greatly reduced. Utility Model Content

DETAILED DESCRIPTION

[0018] like Figure 1-4 In the invention, an airborne laser radar heat dissipation structure includes a main body shell 1, which includes an L-shaped shell plate 101 and a shell bottom cover 102 that are locked together. An L-shaped air duct 103 is provided between the L-shaped shell plate 101 and the shell bottom cover 102, and an air inlet 107 is provided on the shell bottom cover 102. The L-shaped shell plate 101 is provided with a rear vertical plate portion 105, and the side wall of the rear vertical plate portion 105 is provided with an exhaust port 108 connected to the L-shaped air duct 103. A plurality of thermal conductive seats 106 for mounting heating elements are provided on the inner side of the L-shaped shell plate 101.

[0019] The laser radar housing assembly also includes a main cover 2 that is engaged with the main housing 1. The space between the main housing 1 and the main cover 2 is the installation space for the laser radar components. This space is separated from the L-shaped air duct 103 and has a good sealing effect.

[0020] Components with high heat generation, such as core boards and lasers, are mounted on the heat conducting base 106. Since the L-shaped structure widens the contact area with the heat dissipation duct, the heat dissipation efficiency can be effectively improved.

[0021] In a preferred solution, a plurality of heat dissipation fins 109 are provided on one side of the L-shaped shell plate 101 close to the L-shaped air duct 103 , and the plurality of heat dissipation fins 109 are arranged in parallel to form an air duct 110 .

[0022] The heat dissipation fins 109 increase the contact area with the air, and the heat in the component installation space is quickly conducted to the heat dissipation fins 109 through the heat conduction base 106 and is carried away by the air flow.

[0023] In a preferred solution, a centrifugal fan 112 is provided at the air inlet 107 in the L-shaped air duct 103 , and an air outlet of the centrifugal fan 112 faces toward a side close to the exhaust port 108 .

[0024] The centrifugal fan 112 takes in air from the air inlet 107 , and the air outlet of the centrifugal fan 112 blows air from the starting end of the air duct 110 to the exhaust port 108 , quickly taking away the heat on the heat dissipation fins 109 .

[0025] In a preferred solution, each heat-conducting seat 106 is provided with a heat-conducting silicon wafer.

[0026] The heat-conducting silicon chip is placed between the heat-conducting seat 106 and components such as the core board and the laser to ensure good thermal conductivity.

[0027] In a preferred solution, a raised frame portion 111 is provided in the middle of one side of the L-shaped shell plate 101 close to the L-shaped air channel 103 , and the raised frame portion 111 abuts against the shell bottom cover 102 .

[0028] The L-shaped shell plate 101 is also provided with a plurality of raised screw mounting posts. The edge of the shell bottom cover 102 is buckled and sealed with the edge of the L-shaped shell plate 101. The screw mounting posts and the raised frame portion 111 stop the shell bottom cover 102 and are connected with screws here, which not only ensures a stable connection, but also prevents the middle part of the L-shaped shell plate 101 from collapsing, thereby improving the structural strength of the host shell 1.

[0029] In a preferred solution, a front vertical plate portion 104 is provided at one end of the L-shaped shell plate 101 away from the rear vertical plate portion 105 , and a heat conducting seat 106 is provided on the inner side surface of the front vertical plate portion 104 .

[0030] The rear upright 105 and the weight-reducing groove 113 give the L-shaped shell 101 an asymmetrical U-shape, creating a snap-fit ​​stop for the main unit cover 2, facilitating a more secure attachment of the main unit cover 2 to the main unit housing 1. The air inlet 107 is located near one side of the weight-reducing groove 113, and some heating components rest against the inner side of the groove 113, expanding the component installation space.

[0031] A weight-reducing groove 113 is defined on the outer side of the front vertical plate 104 , and the weight-reducing groove 113 does not penetrate the front vertical plate 104 .

[0032] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
