Description

Technical Field

[0001] The invention relates to the technical field of heat insulation of square cabins, in particular to a square cabin large panel with a double-core wrapped composite heat-insulating structure. Background Art

[0002] A shelter is a mobile container with a certain rigidity, strength, and service life. It provides a safe and comfortable shelter for field workers and equipment, significantly improving their quality of life in the field. With the continuous development of shelter manufacturing technology, its application has gradually shifted from its initial military applications to civilian fields such as refrigerated transportation, environmental monitoring, engineering maintenance, and field inspections.

[0003] Large-panel shelters are one of the existing shelter structures. They are constructed from several large composite panels, with edges and corners attached using bolts and rivets. Shelters often face extreme environments such as high temperatures and cold weather. However, their panels are typically insulated using a single layer of homogeneous polyurethane foam. This lacks the same insulation material and structural properties, and generally results in poor thermal inertia. This results in low cabin thermal comfort and high energy consumption, making it unable to meet the increasing demands for thermal comfort, energy conservation, and environmental protection. In severe cases, it can even cause fires, explosions, and other safety hazards. Therefore, the design of a new type of thermal insulation panel for shelters is essential. Summary of the Invention

[0004] In response to the above problems, the present invention provides a double-core wrapped composite insulation structure cabin panel, which effectively improves the thermal insulation performance of the entire cabin panel, enhances the thermal comfort of the cabin environment, extends the service life of the cabin equipment, enhances system reliability and reduces energy consumption.

[0010] The inner heat insulation bridge is fixedly arranged around the surface of the inner skin facing the outer skin, and the outer heat insulation bridge is fixedly arranged around the surface of the outer skin facing the inner skin. The inner heat insulation bridge and the outer heat insulation bridge are respectively fixedly connected to the corresponding surface positions of the frame, thereby forming a central cavity for installing the double-core composite thermal insulation structure. The double-core composite thermal insulation structure is filled in the central cavity;

[0011] The first surface of the inner layer base material is arranged closely against the corresponding surface of the inner skin, the second surface of the outer layer base material is arranged closely against the corresponding surface of the outer skin, the two side surfaces of the middle layer outer frame are respectively arranged closely against the second surface of the inner layer base material and the first surface of the outer layer base material. The inner layer base material, the outer layer base material and the middle layer outer frame enclose a core material filling space. The first layer core material and the second layer core material are arranged in an overlapping manner. The first layer core material is arranged closely against the inner layer base material, the second layer core material is arranged closely against the outer layer base material, and the core layer formed by the combination of the first layer core material and the second layer core material is arranged in the core material filling space.

[0017] The first layer core material is a vacuum thermal insulation board with a thickness of 3 - 20 mm, and the second layer core material is an aerogel with a thickness of 3 - 20 mm.

[0018] After adopting the structure of the present invention, heat insulation bridges are laid on both sides of the frame to play the role of cutting off the heat bridge. The double-core composite thermal insulation structure uses heat insulation materials with good mechanical properties as the base material and vacuum thermal insulation boards and aerogels with smaller thermal conductivity as the core materials, which not only ensures good mechanical properties in all directions of the composite thermal insulation structure, but also reduces the effective thermal conductivity of the composite thermal insulation structure, thereby effectively improving the heat insulation performance of the entire shelter panel, enhancing the thermal comfort of the cabin environment, prolonging the service life of the equipment in the cabin, enhancing the system reliability and reducing energy consumption.
