CN203323321U - Thermal insulation and coldness insulation air hose - Google Patents

Abstract

The utility model provides a thermal insulation and coldness insulation air hose. The lower end of one air hose wall on one side is connected with a reinforcing hole, a dovetail groove is formed in the outer side of the reinforcing hole, the lower end of the other air hose wall corresponds to a dovetail groove, the dovetail grooves of the two air hose walls are connected through a non-metal joint to form a U-shaped groove, and a clamping groove is formed in the outer side of the air hose wall on the side of the reinforcing hole. The outer wall of the air hose is made of metal materials, so that the firm and durable effect and the fireproof performance of metal are achieved, the two air hose walls are connected through the non-metal connector, and the non-metal connector has a very strong thermal insulation and coldness insulation effect so that the entire air hose can have the thermal insulation and coldness insulation performance.

Description

The airduct that a kind of heat insulation is cold

[technical field]

The utility model relates to a kind of ventilation assembly, is specifically related to the cold airduct of a kind of heat insulation.

[background technology]

At present the air-conditioning composite air duct is used breaks away from traditional angle steel, Type of Welding, but not enough place is arranged, although there is fire protection requirement and fastness, it easily produces condensation and dewfall, cause the cold effect extreme difference of heat insulation of airduct, can not reach the relevant energy-saving and cost-reducing requirement of country, and existing airduct adopts aluminium alloy or plastic-steel one-shot forming, because metal has very strong thermal conductivity, thereby fail to solve the cold energy of heat insulation of airduct, although and adopt nonmetallic materials to make to have reduced the heat conductivity problem and can't solve fire prevention and firm requirement.

[utility model content]

In order to overcome the deficiency of existing technology, the utility model provides a kind of heat insulation cold airduct, and it adopts metal and expense metal in conjunction with making airduct have the cold effect of stronger heat insulation, possesses the fire prevention fastness of metal simultaneously.

The technical scheme that the utility model adopts is: the airduct that a kind of heat insulation is cold, one crosswind tube wall lower end is connected with a reinforced hole, there is a dovetail groove in the reinforced hole outside, the corresponding dovetail groove in another wind pipe wall lower end, the dovetail groove of two wind pipe walls connects by nonmetal joint, form " U " type groove, have the wind pipe wall outside of reinforced hole one side that one draw-in groove is arranged.

This airduct outer wall adopts metal material, thereby has firm and durable effect and the fire protecting performance of metal, and two wind pipe walls connect by nonmetal joint, thereby nonmetal joint has, organizes very by force the cold effect of thermal resistance and makes whole airduct, has the cold energy of group thermal resistance.

The utility model beneficial effect: this airduct has the firm and fire resistance of metal, by the conduction of nonmetal connection blocking-up heat, has the good group of cold energy of thermal resistance simultaneously.

For making further to understand feature of the present utility model and technology contents, refer to the utility model drawings and embodiments, yet appended graphic only for reference and explanation use is limited to the utility model.

[accompanying drawing explanation]

Fig. 1 is the utility model structure chart;

In figure, the 1-wind pipe wall; The 2-draw-in groove; 3-" U " type groove; The nonmetal joint of 4-; The 5-reinforced hole; The 6-dovetail groove.

[specific embodiment]

Below in conjunction with drawings and Examples, the utility model is described further:

As shown in Figure 1, the airduct that a kind of heat insulation is cold, one crosswind tube wall (1) lower end is connected with a reinforced hole (5), there is a dovetail groove (6) in reinforced hole (5) outside, the corresponding dovetail groove (6) in another wind pipe wall (1) lower end, the dovetail groove (6) of two wind pipe walls (1) connects by nonmetal joint (4), forms " U " type groove (3), has wind pipe wall (1) outside of reinforced hole (5) one sides that one draw-in groove (2) is arranged.

This airduct outer wall adopts metal material, thereby has firm and durable effect and the fire protecting performance of metal, and two wind pipe walls connect by nonmetal joint, thereby nonmetal joint has, organizes very by force the cold effect of thermal resistance and makes whole airduct, has the cold energy of group thermal resistance.

Yet the better feasible embodiment of above-mentioned only the utility model, non-so limitation the utility model protection domain, do various distortion or apply mechanically all within this technical scheme protection domain according to above-described embodiment.

Claims (1)

1. the airduct that heat insulation is cold, it is characterized in that, one crosswind tube wall lower end is connected with a reinforced hole, there is a dovetail groove in the reinforced hole outside, the corresponding dovetail groove in another wind pipe wall lower end, the dovetail groove of two wind pipe walls connects by nonmetal joint, forms " U " type groove, has the wind pipe wall outside of reinforced hole one side that one draw-in groove is arranged.
