In addition, the device does not need to be provided with a large-size supporting plate, occupies a small space and can be used for installing a residual larger space for circuit devices in the cabin section. Specifically, the method comprises the following steps:
(1) the installation of the heat dissipation device in the cavity with a narrow inlet can be realized. The traditional radiating circuit support of the underwater sealed cavity requires the same shape and size as those of the inner wall of the cavity, so that the heat of a device is transferred to the wall of the cavity, but the structure is not suitable for cabin sections with two contracted ends, and the installation of the radiating circuit support cannot be realized. The distance between the upper heat-conducting block and the lower heat-conducting block of the heat dissipation device is adjustable, so that the heat dissipation device can be successfully assembled into the cabin section through the inlet part with the narrower cavity.
(2) The upper heat-conducting block and the lower heat-conducting block are in close contact with the inner wall of the cabin section, and the heat dissipation performance is good. In the cabin section, the vertical height of the diamond expansion bracket is adjusted, so that the upper heat conduction block and the lower heat conduction block can be kept in close contact with the inner wall of the cabin section, and the contact surface is filled with heat conduction silicone grease, so that the thermal resistance can be further reduced. If a larger gap exists on the binding surface, the heat conduction effect is improved through the heat conduction of the copper wires pre-filled in the lightening grooves. The self-locking property of the thread pair is utilized, the stability of the height position of the diamond expansion bracket can be kept, and the temperature rise of a circuit device is controlled.
(3) The diamond expansion bracket amplifies the displacement of the supporting rod, and the hexagonal prism section arranged on the upper part of the supporting rod can be conveniently rotated by a wrench, so that the installation is labor-saving. The height adjusting piece adopts the threaded transmission structure, and compared with a hydraulic pneumatic ejection structure, the structure is simpler, and complex loop control and energy parts are not needed. The device uses rhombus expansion bracket and altitude mixture control spare cooperation, compares in ordinary rhombus expansion bracket, to cavity application environment under water, altitude mixture control spare sets up the bracing piece for six prismatic sections for upper portion, can directly use the spanner to twist at cabin section entrance and change, with the passive rotation conversion of bracing piece displacement on the vertical direction, directly promotes the backup pad to it is flexible to drive whole rhombus expansion bracket. For a heavy circuit and a heat conducting device, the special mode reduces the difficulty of installation and saves labor in operation. The multi-stage diamond-shaped mechanism of the lifting mechanism can amplify the displacement of the lifting plate, and compared with a mode of directly adopting stud lifting, the connection point is firmer, and the required thread length is shorter.
(4) Simple structure, the dismouting of being convenient for, and have great space utilization. The traditional heat dissipation support structure is separated into the upper heat conduction block and the lower heat conduction block, circuit devices can be directly fixed on the heat conduction blocks, the two rhombic expansion brackets are used as supporting structures and symmetrically arranged in the cabin section cavity, stable supporting can be achieved, a large-size supporting plate does not need to be arranged inside the device, occupied space is small, and the larger space can be left for installation of the circuit devices inside the cabin section. Compared with other modes that the guide rail is installed in the interior of the movable support, the utilization rate of the interior space is higher.
