Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a profile corner connection structure for a thick foam board used in the foam box of a central air conditioning terminal device. Background Technology

[0002] Central air conditioning terminal equipment is a product that delivers air to activity areas to meet the requirements of temperature, humidity, and cleanliness. During operation, to ensure the targeted delivery of air that meets the requirements, the internal power units, such as fans and motors, clean air filters, humidification and dehumidification devices, and energy exchange devices, need to be enclosed in a specially designed enclosure. The enclosure needs to meet strength requirements, insulation requirements, and a certain degree of airtightness. Currently, most products use a sandwich foam panel structure, with thick foam panels spliced ​​together according to specific specifications to form the enclosure. The thick foam panel includes a metal frame, foam material, inner sheet metal attached inside the foam material, and outer sheet metal attached to the outside of the foam material. However, part of the metal frame is in contact with the interior of the foam enclosure, and because it is made of metal, its heat transfer performance is stronger than that of the foam material. Therefore, the presence of the metal frame creates a cold bridge between the inner and outer sheet metal, causing condensation on the outer surface of the thick foam panel, affecting its use. Furthermore, the assembly process is cumbersome, the strength is limited, and the assembly precision is not high.

[0003] In view of the problems existing in the above-mentioned existing technologies, it is necessary to study and design a new type of thick foamed board profile corner connection structure to overcome the problems existing in the existing technologies. Summary of the Invention

[0004] The existing metal frame design suffers from cold bridges between the inner and outer sheet metal, causing condensation on the outer surface of the thick foam panel and affecting its use. Furthermore, the assembly process is cumbersome, strength is limited, and assembly precision is low. Therefore, a new profile corner connection structure for thick foam panels is provided to ensure the performance of the thick panels, including but not limited to a reliable structure with large panel thickness, convenient and efficient installation, high connection strength and precision, and no cold bridges in the connection.
