Problems solved by technology

However, in the existing radiant ceiling products, there is a problem that the fins have a small wrapping surface for the coil, which wastes part of the heat exchange effect of the heat exchange surface of the coil, resulting in the unsatisfactory heat exchange effect of the entire ceiling.
[0003] Chinese patent CN203964148U discloses a radiant air-conditioning terminal combined with a metal ceiling board, which mainly includes a metal ceiling board, copper pipes, aluminum base, aluminum foil and insulation materials; the copper pipe is wrapped by an aluminum base and a metal ceiling board, Aluminum foil and insulation material are arranged above the aluminum base; the metal ceiling board can be a perforated board or a non-perforated board; in this patent, the copper pipe is wrapped by the aluminum base and the metal ceiling board to prevent the copper pipe from falling off, but the copper pipe There is a contact connection with the metal base, and the metal base and the copper tube are only in contact with the upper part, and the contact area is small, resulting in poor heat exchange effect of the heat exchange tube

Abstract

The invention relates to a metal radiation ceiling board. The metal radiation ceiling board comprises a metal pinch plate, sound insulation cotton, a radiating unit, a phase change energy storage material and a heat insulation layer. The radiating unit comprises a plurality of fins arranged in parallel. Each fin is internally provided with a penetration straight pipe in the length direction of the fin. The penetration straight pipes in the fins communicate through connecting pipes in sequence to form a channel allowing heat exchange fluid to circulate. Compared with the prior art, the connecting pipes in the metal radiation ceiling board are directly processed in the fins; each connecting pipe and the corresponding fin are of an integrated structure; contact thermal resistance caused by a traditional external coil is avoided, and the heat exchange effect is improved; and the metal radiation ceiling board has the advantages of high heat exchange efficiency and energy utilization rate, good in heat retaining capacity, low noise and the like.

Description

technical field [0001] The invention relates to the field of metal radiant ceilings, in particular to a metal radiant ceiling board and a preparation method thereof. Background technique [0002] Ceiling radiant cooling / heating is a form of air conditioning system, and its heat exchange tubes are installed above the ceiling, making the ceiling the main component of the air conditioning system. Compared with the traditional air-conditioning system, the metal radiant ceiling system has considerable comfort and environmental health, the largest degree of architectural freedom, good heat transfer effect, high heat transfer efficiency per unit area, and a higher energy efficiency throughout the life of the building. features such as energy efficiency. Radiant ceilings have been widely used in some public large buildings. However, in the existing radiant ceiling products, there is a problem that the wrapping surface of the fins on the coil is small, which wastes part of the heat...
