Anti-condensation fresh air pipe made of new thermal insulation material

Abstract

The invention discloses an anti-condensation fresh air pipe made of a new thermal insulation material. The anti-condensation fresh air pipe made of the new thermal insulation material comprises a baseplate. The upper surface of the base plate is fixedly connected with the lower surface of a top plate through a plurality of supporting plates. A cavity is formed between every two adjacent supporting plates. A first chamfer, a second chamfer and a third chamfer are formed in the upper surface of the top plate. The base plate can be folded according to the first chamfer, the second chamfer and the third chamfer in sequence to form a rectangle. According to the anti-condensation fresh air pipe made of the new thermal insulation material, because the first chamfer, the second chamfer and the third chamfer are formed, the base plate can be folded according to the first chamfer, be folded again according to the second chamfer and be folded according to the third chamfer, the left end of the base plate can be in lap joint with the right side face of the base plate, the left end of the upper surface of the top plate can be in lap joint with the right side face of the top plate, the base plate can be folded into the rectangle, the pipe will not rust, and is low in cost is low and small in weight, and construction is convenient to carry out.

Description

technical field [0001] The invention relates to the technical field of air ducts, in particular to a novel anti-condensation fresh air duct of a novel thermal insulation material. Background technique [0002] The composition of the air duct: The air duct is the piping system used for air transportation and distribution. Ducts can be classified by section shape and material. According to the cross-sectional shape, air ducts can be divided into circular air ducts, rectangular air ducts, oblate air ducts, etc. Among them, circular air ducts have the largest height with the smallest resistance and are complicated to manufacture. So the application is mainly rectangular duct. According to the material, air ducts can be divided into metal air ducts and composite air ducts. [0003] Traditional central air-conditioning ducts are generally made of white iron sheet, which is prone to condensation at 5-7 degrees Celsius, which will cause the iron sheet to rust for a long time, so ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new anti-condensation fresh air duct of thermal insulation material, which solves the problem that traditional central air-conditioning air ducts are generally made of white iron sheets, and the iron sheets are prone to condensation when the temperature is 5-7 degrees Celsius. A long time will cause the iron sheet to rust, so it is necessary to attach a layer of heat insulating material inside the iron sheet, and the cost of the iron sheet is high and the weight is heavy, which will cause inconvenience to the construction
