Heat dissipation sealed bucket and underwater robot

Abstract

The invention provides a heat dissipation sealing bucket and an underwater robot, which belong to the technical field of underwater equipment. The heat dissipation sealing bucket includes a cylinder body, an end cover, a cooling fin, a fixing piece and an elastic component. Among them, there are two end caps, and the two end caps are respectively blocked on the axial ends of the cylinder; one side of the heat sink is attached to the inner wall of the cylinder, and the other side is used to fix the heating element; the fixing part is located in the cylinder , the two ends of the fixing piece are fixedly connected to the two end caps; the elastic component is supported between the fixing piece and the heat sink, so as to use its elastic force to make the heat sink close to the inner wall of the cylinder. The heat dissipation fins of the heat dissipation sealing barrel can always be closely attached to the inner wall of the cylinder, and the heat dissipation efficiency is high and stable, which can meet the heat dissipation requirements of heating components when working underwater.

Description

technical field [0001] The invention belongs to the technical field of underwater equipment, and in particular relates to a heat-dissipating sealed barrel and an underwater robot. Background technique [0002] Due to the needs of underwater work, underwater robots generally have strict waterproof requirements, and usually need to set up a sealed barrel to separate the components from the water environment. [0003] At present, the heat of the components is transferred to the sealed barrel through the air, and then transferred to the outside through the sealed barrel to achieve heat dissipation. However, only relying on the sealed barrel to dissipate heat has low heat dissipation efficiency and cannot meet the heat dissipation requirements of components when working with high power. Patent CN108668514A discloses a power supply system for an underwater micro-robot, which dissipates heat from the power supply system through a heat sink attached to the shell. However, the heat s...

Problems solved by technology

[0003] At present, the heat of the components is transferred to the sealed barrel through the air, and then transferred to the outside through the sealed barrel to achieve heat dissipation. However, only relying on the sealed barrel for heat dissipation, the heat dissipation efficiency is low, and it cannot meet the heat dissipation requirements of the high-power components.

Patent CN108668514A discloses a power supply system for underwater micro-robots, which dissipates heat from the power supply system through heat sinks attached to the shell, however, the heat sink is only pasted on the shell with heat-conducting silicone grease. When working underwater, the heat sink is easily separated from the shell when it is shaken, and the heat dissipation effect cannot be guaranteed
