Air-conditioner box with aluminum-plastic composite type plane fastening structure

Abstract

The invention relates to an air-conditioner box with an aluminum-plastic composite type plane fastening structure. A No.1 frame aluminum profile and a No.2 frame aluminum profile are fastened into an integrated profile and form a left air-conditioner box plate together with an outer panel, an inner panel, foaming polyurethane and foamed rubber; a No.3 frame aluminum profile and a No.4 frame aluminum profile are fastened into an integrated profile and form a right air-conditioner box plate together with the other outer panel, the other inner panel, the other foaming polyurethane and the other foamed rubber; and the two air-conditioner box plates are fixedly connected to form plane fit through bolts and nuts. The aluminum-plastic composite type air-conditioner box with the plane fastening structure disclosed by the invention overcomes the defects of insufficient rigidity of an air-conditioner box body, low bearing static pressure, high deformation rate, poor heat insulation and preservation effects, cold bridge and the like. According to the aluminum-plastic composite type air-conditioner box with the plane fastening structure disclosed by the invention, the air leakage rate is reduced; the cold bridge can be avoided by an aluminum-plastic composite profile; deformed steel is inserted to the profile so as to greatly enhance the rigidity of the profile and be capable of resisting positive and negative pressures; after oppositely spliced, the profiles can be inserted to an aluminum alloy cover plate without exposing screws so as to be beneficial to the application of high-end purification and enhance the strength of the air-conditioner box; and moreover, the rigidity of the air-conditioner box is further strengthened by an internal reinforced rib and an external reinforced rib.

Description

technical field [0001] The invention relates to an air-conditioning box structure, in particular to an aluminum-plastic composite plane fastening structure air-conditioning box. Background technique [0002] Before the present invention, air-conditioning boxes on the market can be roughly divided into frame-type air-conditioning boxes and frameless-type air-conditioning boxes. Most frame-type air-conditioning boxes are framed by columns, and the panels are embedded in the frame. Due to the use of clearance fit, there are inevitably problems of poor sealing and high air leakage rate. The frameless air-conditioning box is supported by a variety of plastic-steel profiles to form its box support. The disadvantages are that the rigidity is not enough, the static pressure it bears is low, and the deformation rate of the box is high. In addition, both of these two air-conditioning boxes have poor heat insulation effects, which cannot solve the problem of cold bridges. Contents o...

Problems solved by technology

Most frame-type air-conditioning boxes are framed by columns, and the panels are embedded in the frame. Due to the use of clearance fit, there are inevitably problems of poor sealing and high air leakage rate.

The frameless air-conditioning box is supported by a variety of plastic-steel profiles to form its box support. The disadvantages are that the rigidity is not enough, the static pressure it bears is low, and the deformation rate of the box is high.

In addition, both of these two air-conditioning boxes have poor heat insulation effects, which cannot solve the problem of cold bridges
