Problems solved by technology
This structure often encounters many problems in the actual use process. First, due to the heat conduction of the C-shaped metal sheet metal inside and outside the air handler, it is easy to cause condensation at the air outlet; secondly, when the structure is installed, the C-shaped sheet metal There will be a matching gap between the air outlet and the air outlet. The size of the gap will not only cause air leakage, but also affect the appearance effect; thirdly, the C-shaped sheet metal has cutting, punching, bending and other processes, and the production is relatively complicated, which not only reduces the assembly efficiency but also increases the In addition, due to the heat conduction characteristics of metal sheet metal, it is destined to produce cold bridges, resulting in the phenomenon of condensation

The invention provides a heat insulation plate with an air port cold bridge frame. The heat insulation plate comprises a heat insulation plate body and an air port cold bridge frame assembly arrangedin the heat insulation plate body, wherein an outer metal plate and an inner metal plate of the heat insulation plate body are connected to the two sides of the air port cold bridge frame assembly through PE cotton with the two faces provided with glue respectively, and a heat insulation layer filled with polyurethane is defined by the outer metal plate, the inner metal plate and an outer frame; and an air port is defined by an air port frame of the air port cold bridge frame assembly and penetrates through the heat insulation plate body, and the air port frame is made of rigid polyvinyl chloride. The heat insulation plate solves the problems of heat conduction and moisture condensation when the inner metal plate and the outer metal plate directly cover the metal plates, and also solves the problems that exposed scraps of polyurethane heat insulation materials pollute the environment and overflow in the machining and manufacturing process.
Description
technical field [0001] The invention relates to the field of heat insulation, in particular to a thermal insulation board with a tuyere broken cold bridge frame. Background technique [0002] In the central air-conditioning system, the insulation effect of the cabinet directly affects the operating efficiency of the air-conditioning unit. If there is a direct contact between the metal surface and the metal surface in the cabinet structure, there will be a cold bridge problem, which will damage the building. It will not only increase the cooling consumption of the room and waste the energy for cooling; but also will have condensation on the high temperature side, which will affect the insulation performance of the insulation material; it will also affect the use of the room on the high temperature side. [0003] At present, the terminal air handlers used in central air conditioning, such as figure 1 shown and figure 2 As shown, the air outlet on the insulation board is gen...
