[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] The present embodiment provides a heat pipe type heat dissipation component suitable for an underwater unmanned vehicle, which utilizes a heat pipe to dissipate heat from internal heating elements of the unmanned vehicle, can achieve rapid heat transfer, and meet the heat dissipation requirements of the underwater unmanned vehicle.

[0025] like Figure 1 As shown, the heat dissipation component includes: a collector 1, a heat pipe 2 and a condenser 3.

[0026] like Figure 2As shown, the collector 1 serves as the heat collecting end of the heat dissipation assembly; the components to be dissipated (i.e., components with a large amount of heat) inside the underwater unmanned vehicle are mounted on the upper surface of the collector 1, so that the heat of the components to be dissipated is transferred to the inside of the collector 1 through heat conduction. The collector 1 generally uses materials with high thermal conductivity, such as aluminum alloy, copper alloy, etc., which can achieve rapid heat transfer of the components to be dissipated. Mounting holes are reserved on the surface of the collector 1, and its upper surface fits the components to be dissipated and is connected by tightening screws. In order to ensure more uniform heat transfer between the components to be dissipated and the collector 1, thermal grease can be evenly applied on the upper surface of the collector 1 to increase the thermal conductivity between the hot end components and the collector 1, so as to ensure that heat can be quickly transferred from the components to be dissipated to the collector 1.

[0027] The dimensions and corresponding mounting interfaces of the heat collector 2 can be appropriately adjusted according to the dimensions and mechanical interfaces of the actual heat dissipation components. At the same time, the material of the heat collector 2 can be selected according to the actual heat transfer, such as aluminum alloy or other materials with high thermal conductivity, to ensure rapid heat transfer.

[0028] like Figure 3 As shown, the heat pipe 2 serves as the heat transfer end of the heat dissipation component, a part of which is pre-buried inside the collector 1 to absorb the heat from the collector 1, and a part of which extends to the inner wall of the cabin 4, thereby transferring the heat collected by the collector 1 to the wall of the cabin 4. The circulating working fluid in the heat pipe 2 is generally selected from copper / water, stainless steel / ammonia, aluminum / acetone, etc.; the circulating working fluid inside the heat pipe 2 absorbs the heat from the collector 1, causing the circulating working fluid to undergo phase change and absorb heat, and the working fluid moves inside the heat pipe 2 in a two-phase state. The interior of the heat pipe 2 is a porous structure of sintered metal powder, and the porous structure provides the capillary force required for the working fluid circulation, so that the circulating working fluid can transfer heat to the arc position of the cabin 4, thereby realizing the transfer and diffusion of heat.

[0029] As an example, Figure 3 As shown, a plurality of heat pipes 2 are arranged in parallel, and the heat pipes 2 have a horizontal portion pre-buried inside the collector 1 and an arc portion having the same shape as the inner wall surface of the chamber 4 .

[0030] As an example, a plurality of heat pipes 2 are symmetrically arranged on both sides of the collector 1, so as to diffuse the heat collected by the collector 1 to the walls of the cabin 4 on both sides.

[0031] like Figure 4As shown, the condenser 3 serves as the heat dissipation end of the heat dissipation component. The circulating medium inside the heat pipe 2 undergoes a phase change at the condenser end. Part of the gaseous medium changes phase into a liquid medium, releasing a large amount of latent heat of vaporization, transferring the heat from the collector end to the condenser end, releasing heat at the condenser end, and recondensing into liquid. The liquid then flows back to the evaporator end under the capillary force inside the heat pipe 2, and the cycle continues. The shape of the condenser 3 is consistent with the shape of the inner wall of the cabin 4, so that it can fit closely with the inner wall of the cabin 4, and then transfer heat to the wall of the cabin 4, realize heat exchange, and then dissipate heat through the wall of the cabin 4.

[0032] The portion of the heat pipe 2 extending to the inner wall of the cabin 4 passes through the entire condenser 3, transferring the heat absorbed by the heat pipe 2 to the condenser 3; corresponding mounting holes are reserved between the condenser 3 and the inner wall of the cabin 4, and the condenser 3 is tightly fitted to the inner wall of the cabin 4 by tightening the screws.

[0033] As an example, in order to facilitate the processing and installation of the condenser 3, the condenser 3 is segmented, including a plurality of arc-shaped condensation sections spaced apart along the circumference of the cabin body 4.

[0034] The number and extension length of the heat pipes 2 can be appropriately adjusted according to the actual dimensions of the cabin 4 to adapt to the cabin installation interface. The mechanical installation interface between the condenser 3 and the cabin 4 can be made into a corresponding matching installation port according to the actual situation of the cabin, which will not affect the actual heat dissipation effect.

[0035] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
