Marine refrigerator body with welded aluminum honeycomb totally enclosed concave tray

Abstract

The invention discloses a marine refrigerator body with a welded aluminum honeycomb totally enclosed concave tray. The marine refrigerator body comprises a frame, galvanized steel plates wrapped outside the frame, a thermal insulation layer filled between different parts of the frame, a welded aluminum honeycomb totally enclosed concave tray arranged at the bottom of the inner side of the frame, wall plates arranged around the inner side of the frame, and a ceiling arranged at the top of the inner side of the frame. The welded aluminum honeycomb totally enclosed concave tray is formed by welding welded aluminum honeycomb plates after the welded aluminum honeycomb plates are mounted at the bottom of the inner side of the frame; the welded aluminum honeycomb plates comprise a flat-plate welded aluminum honeycomb plate and a straight-angle welded aluminum honeycomb plate, the flat-plate welded aluminum honeycomb plate forms a planar part of the welded aluminum honeycomb totally enclosed concave tray, and the straight-angle welded aluminum honeycomb plate forms ambient corner parts of the welded aluminum honeycomb totally enclosed concave tray; and stainless steel countersunk screws for the welded aluminum honeycomb plates are mounted at the bottom of the inner side of the frame after penetrating through an aluminum alloy embedded block, and joints of rust-proof patterned aluminumplates on the surfaces of the welded aluminum honeycomb plates after splicing are welded fully enclosed by argon arc welding. The welded aluminum honeycomb plate is formed by brazing a rust-proof patterned aluminum plate, an aluminum honeycomb core, a rust-proof aluminum plate and an aluminum alloy embedded block. The marine refrigerator body with a welded aluminum honeycomb totally enclosed concave tray, provided by the invention, is mainly applied in the field of marine refrigerators for food preservation on ships and submarines. A totally enclosed concave tray is formed at the bottom of themarine refrigerator, so that the marine refrigerator has the advantages of no water leakage, light weight, good heat preservation performance, high strength and rigidity, and good fire prevention performance.

Description

technical field [0001] The invention relates to a marine cold storage body with a welded aluminum honeycomb fully enclosed concave tray. Background technique [0002] At present, the bottom structure of the marine cold storage body is generally filled with a polyurethane insulation layer between the wooden frames, plywood is installed on the wooden frame, stainless steel plates are laid on the plywood, and glue is used to fill the joints between the stainless steel plates. This brings about a more serious problem. After long-term use, the performance of the caulking glue between the stainless steel plates will decrease and fail. Because the cold storage floor sometimes produces water, although there is a floor drain for drainage, water will also leak between the joints of the stainless steel plates. It makes the wooden board and even the wooden frame under the stainless steel plate moldy and rotten. This problem makes the marine cold storage must be refurbished after severa...
