The invention relates to a deep-sea
organism outboard heat preservation device. The deep-sea
organism outboard heat preservation device comprises a pressure-proof inner shell, and the pressure-proof inner shell is internally provided with a cavity. A pressure-proof
enclosure bulkhead is connected to the pressure-proof inner shell, wherein the pressure-proof
enclosure bulkhead is in a
barrel shape and communicates with the cavity. A hatch cover is connected to the outer side face of the pressure-proof
enclosure bulkhead, and an electric balance valve is mounted on the hatch cover. A pressure-proof outer cabin is arranged outside the pressure-proof inner shell, and a
closed cavity is formed by connecting a first pressure-proof outer shell and a second pressure-proof outer shell through a
flange. The side, close to the hatch cover, of the first pressure-proof outer shell is fixedly connected to the pressure-proof enclosure bulkhead. A water inlet cabin penetration part and a water outlet cabin penetration part are mounted on the second pressure-proof outer shell in a spaced manner. A circulating water pump is mounted in a gap formed between the inner wall of the pressure-proof outer cabin and the outer wall of the pressure-proof inner shell. An input end
pipe of the circulating water pump is connected with the water inlet cabin penetration part, and an output end
pipe is connected with multiple
semiconductor refrigeration assemblies arranged on the outer wall of the pressure-proof inner shell in the circumferential direction. The
semiconductor refrigeration assemblies are connected with the water outlet cabin penetration part through pipes and electrically connected with a
control system in a submersible cabin. By means of the deep-sea
organism outboard heat preservation device, the
automation degree is raised, and the in-situ fidelity is improved.
