The device is simple in structure, wall-attached heat dissipation of circuit devices in the underwater cavity can be achieved under the condition that the size of an inlet is small, and the heat dissipation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation equipment, and in particular relates to a heat dissipation device used for a shrinkage cabin section at both ends of an underwater sealed cavity. Background technique [0002] In scenarios such as deep-sea exploration, dam inspection and maintenance, automatic unmanned underwater vehicles (AUVs) and some other underwater vehicles have great application space. Underwater vehicles such as AUV generally need to be equipped with specific detection equipment, and these equipment usually require power supply. In order to realize underwater operations, the circuit components of the detection equipment need to be loaded in an underwater sealed cavity. The power consumption generated by this type of equipment cannot be ignored. In the case of long-term underwater operation, if the circuit components cannot dissipate heat in time, the performance of the circuit will be affected. When the temperatur...
