Square cabin with air flow sandwich layer in cabin wall

Abstract

The invention discloses a square cabin with an air flow sandwich layer in a cabin wall, and belongs to the field of heat dissipation design. The square cabin comprises a cabin body framework, cabin body layer plates and an air inlet channel combination. The cabin body layer plate comprises an inner skin layer, a heat insulation layer, a partition board layer, the air flow sandwich layer and an outer skin layer, the six cabin body layer plates are fixed into six space faces of the cabin body framework, the air flow sandwich layer is fixed between the heat insulation layer and the outer skin layer through a flow sandwich layer framework, the flow sandwich layer framework is fixed to the outer side of the cabin body framework through cabin body connecting corner parts, the side wall of the flow sandwich layer framework is provided with multiple through holes serving as framework air inlets and framework air outlets, the flow sandwich layer framework communicates with the air flow sandwichlayer and is used for achieving flowing of air in the air flow sandwich layer, and the air inlet channel combination exhausts and supplies air for the air flow sandwich layer in the cabin body layerplates through a fan. Flowing air is used for instantly bringing away heat, radiated to the surface of the square cabin, of the sun outside, and the phenomenon that due to the fact that the heat is accumulated in the heat insulation layer of the cabin wall and a cabin top plate, and the in-cabin environment temperature rises can be avoided.

Description

technical field [0001] The invention belongs to the field of heat dissipation design, and in particular relates to a shelter with an air interlayer in the bulkhead, which reduces the transmission of external heat radiation energy into the cabin by changing the bulkhead structure of the shelter. Background technique [0002] The square cabin can be called a "house" that can move as a whole and is protective. It is widely used in the fields of command system, communication, medical treatment, logistics support, etc., and the use environment is mostly in the wild. For heat insulation, the six wall panels (roof, front wall, right wall, left wall, rear wall, bottom plate) of the shelter are usually filled with heat insulating materials. However, when the cabin is exposed to high-intensity solar radiation (especially in hot summer or desert areas) for a long time, the insulation material in the bulkhead will accumulate a lot of heat, and the heat will be transferred to the inner s...

Problems solved by technology

Patent 201911155707.9 discloses a special compartment or cabin heat insulation material and structure, which is composed of a high reflective layer and a high thermal resistance layer in the high temperature heat insulation layer and a high reflective layer and a high thermal resistance layer in the low thermal insulation layer. The multi-layer structure reduces heat transfer, but the multi-layer structure is directly in contact with solar radiation, and in a long-term, high-intensity solar radiation environment, it will still cause the multi-layer structure to accumulate a large amount of heat and transfer it to the cabin
