The utility model discloses a plate type heat insulation structure for a low-temperature storage tank, the plate type heat insulation structure comprises a plurality of heat insulation pieces which are adjacently lapped, each heat insulation piece comprises a positioning rod used for being fixed on the low-temperature storage tank, and one end of the positioning rod far away from the low-temperature storage tank is provided with a positioning plate; a sliding layer is arranged at the position, corresponding to the positioning plate, of the first heat insulation plate, and the sliding layer makes contact with the surface of the positioning plate and can slide relative to the positioning plate; the second heat insulation plate is arranged on the side, away from the low-temperature storage tank, of the first heat insulation plate; a trapezoid inner groove is formed between every two adjacent second heat insulation plates, the trapezoid inner grooves are filled with foaming polyurethane foam, and the space between every two adjacent first heat insulation plates is filled with an elastic compensation layer. The heat insulation structure is not prone to cracking when the low-temperature storage tank expands with heat and contracts with cold.

The utility model relates to the technical field of box wallboard, disclose a kind of box wallboard structure of high efficiency prevents cold bridge, including refrigeration box, and refrigeration box two sides symmetry are provided with wallboard, and wallboard includes veneer, and fill slot is opened in veneer, and heat preservation board is provided in veneer, and inner layer soft board is provided on veneer, and hollow layer is provided between heat preservation board and inner layer soft board, and hollow layer is filled with argon, and heat insulation in refrigeration box can be realized using heat preservation board, and hollow layer is arranged between inner layer soft board and heat preservation board, when pork impacts inner layer soft board, inner layer soft board will be appropriately deformed, while argon in hollow layer will be compressed, and then the impact force brought by pork impacting inner layer soft board is consumed, while argon is lower than air heat conduction coefficient, to further improve the temperature insulation effect of box wallboard, avoid the heat conduction path at its fracture after heat preservation layer fracture, and then cold bridge appears, improve the refrigeration effect of the pork transported, and guarantee the freshness of pork.

The utility model discloses a modularized fresh air dehumidifier which comprises a machine shell, a plurality of heat preservation plates arranged in the machine shell, a fan module, a coil pipe module, a filter screen module, an electric control module, a fresh air opening, an air return opening and an air supply opening, and the fresh air opening, the air return opening and the air supply opening are formed in the machine shell. The fan module is arranged on one side of the shell, the coil module is arranged on the other side of the shell, the fresh air inlet and the return air inlet are arranged on the other side of the shell in parallel, the fresh air inlet and the return air inlet are connected with the filter screen module, the heat preservation plates are arranged on the periphery of the inner wall of the shell, and the shell is isolated from the fan module, the coil module, the filter screen module and the electric control module through the heat preservation plates. The sealing device is good in sealing performance, high in reliability, flexible in configuration and easy to maintain.
