Description

Hinge-structured block type vacuum heat loss prevention device The present invention relates to a hinge-structured block-type vacuum heat loss prevention device for reducing heat loss in piping, preventing freezing, and reducing the hassle of the installation process. Korean Registered Patent Publication No. 10-2584572 (October 6, 2023) discloses a cryogenic vacuum insulated piping for ships for transporting cryogenic fluids without heat loss. A cryogenic vacuum insulation pipe for ships includes a loop pipe having a bending shape that connects multiple pipes, an insulation pipe that surrounds the multiple pipes and the loop pipe, and one or more sliding supports that maintain an insulation gap between the loop pipe and the insulation pipe by being positioned on the loop pipe to support the space between the loop pipe and the insulation pipe. One or more sliding supports include an inner support that wraps around a loop pipe, an outer support that is radially spaced from the inner support and supported by the inner support and the insulating pipe, and an annular connecting member that elastically connects the inner support and the outer support. The inner support has a longer length than the outer support, and one or more sliding supports further include a first annular ring that wraps around the loop pipe at one end of the inner support and supports the inner support apart from the loop pipe but is not fixed to the loop pipe, and a second annular ring that contacts the insulation pipe at one end of the outer support and supports the outer support apart from the insulation pipe but is not fixed to the insulation pipe. The annular connecting member includes an annular insertion portion that is inserted and joined between the other end portions of the inner support and the outer support, and an annular protrusion portion that protrudes outward from the annular insertion portion and has its upper and lower portions supported at the other end portions of the inner support and the outer support. The annular connecting member, the first annular ring, and the second annular ring include a heat-blocking material that blocks heat transfer. One or more sliding supports absorb and support shrinkage deformation applied to the insulation pipe and the roof pipe by allowing relative movement between the insulation pipe and the roof pipe, and block heat transfer between the insulation pipe and the roof pipe. Korean Published Patent Application No. 10-2024-0071914 (May 23, 2024) describes a support for a vacuum insulated pipe for maintaining the stability of a vacuum insulated pipe and a vacuum insulated pipe having the same. A support for vacuum-insulated piping comprises an inner tube through which an ultra-low temperature fluid flows, an outer tube installed at a certain distance from the outer side of the inner tube, and a vacuum layer formed between the inner tube and the outer tube. A support for a vacuum-insulated pipe comprises a support body formed to extend along the circumferential direction within a vacuum layer, a plurality of inner support members arranged at predetermined intervals along the circumferential direction on the support body and formed to protrude radially inward to be in close contact with the outer surface of an inner pipe, and a plurality of outer support members arranged between the inner support members on the support body and formed to protrude radially outward to be in close contact with the inner surface of an outer pipe.
