Abstract

The utility model relates to an aluminium alloy warm-air radiator. An extrusion forming ribbed pipe of the aluminium alloy is used as a radiating pipe. The heating medium delivery pipes are all thick-wall pipes, and thus the pressure bearing is high and the corrosion resistance is strong. Hot water and steam both can be used as the heating medium. Because the aluminium alloy sectional materials are used, thus the utility model has the advantages of strong ornamental performance, light weight and convenient installation. The utility model not only can be applied to the low and the high buildings, but also can be applied to high grade buildings, such as hospitals, hotels, etc.

Description

Multi-purpose Al alloy warm-air radiator

The utility model relates to the dim gas radiator of aluminium alloy of dim logical heat abstractor, particularly a kind of extrusion modling.

Existing dim logical radiator mainly contains cast iron and steel two big classes, and their heavinesses are ornamental poor.On serviceability, cast iron class pressure-bearing is low, can not go up skyscraper.Though steel pressure-bearing height, poor corrosion resistance, especially anti-steam corrosion is poorer.

" the dim gas heat abstractor of wall-hanging aluminium matter " that China Patent No. " 92214822.8 " is showed, though also adopted extrusion modling aluminium radiating tube, rubber parts is used in many places in its structure, and pressure-bearing is low, and applicability is limited.

Task of the present utility model provides the dim gas radiator of many applicabilities aluminium alloy that a kind of good decorative property, pressure-bearing height and corrosion resistance are better than steel.

The utility model is finished as follows: with the aluminium alloy radiating tube of extrusion modling, combination is as required vertically arranged, and is communicated with aluminium alloy water inlet (vapour) pipe that keeps flat on it, it is communicated with aluminium alloy water outlet (vapour) pipe that keeps flat down, makes one group of radiator after argon arc welding or oxygen welding welding.They connect with building containing of main pipe rail, adopt technique known such as gas thread or ring flange to get final product.

Below, the utility model is further described in conjunction with the accompanying drawings with embodiment.

Fig. 1 is the sectional schematic diagram of radiating tube among the embodiment.

Fig. 2 is the front elevation of radiating tube arranged vertical assembly welding.

Fig. 3 is the front elevation that radiating tube is forward arranged assembly welding.

As can be seen from Figure 1, the profiled outline of radiating tube 1 is rectangle, and it is made of the garden pipe 2 of centre and

fin

3,4 all around.The garden is effective, and fin is arranged in parallel with the conducting heating agent, holohedral symmetry, and in order to dispel the heat to air, they are extrusion modlings.Garden pipe 2 is that external diameter is the thick-walled pipe about 25mm, and the thickness of

fin

3,4 is about 1mm, and this thickness both can satisfy the heat transfer requirement, can save metal again.Fin 3 externally has the shell effect concurrently.It stretches out, and receives in the end, forms cavity volume, and it is outwards heat radiation both, again inwardly heat radiation.Fin 4 dispels the heat in cavity volume in cavity volume.

As can be seen from Figure 2, water-in and water-out (vapour) pipe 5 and 6 is arranged horizontally, and radiating tube 1 is vertical layout betwixt, and the direction of its fin is vertical with pipe 5 pipes 6.The radiator of this structure is arranged closelyer, and length is short, but thickness is the long limit of radiating tube 1, is thick type.

From Fig. 2, it can also be seen that, water inlet (vapour) pipe 5 tail end, soldering and sealing one plug, dress runs air-valve 7 on the plug.For with building main pipe rail interface, pipe 5 and pipe 6 should be the thick-walled pipe of external diameter 27 or 33mm, interface can connect also available flange with conventional pipe tooth and connect (this figure omits and draws).

As can be seen from Figure 3, different with Fig. 2 is, radiating tube 1 has rotated 90 degree, and its fin and pipe 5 and pipe 6 are in the same way, and be and end to end, and the cavity volume that fin 3 is formed is closed, helps the hot-air convection chamber in, the raising coefficient of heat transfer.The radiator of this kind structure, its thickness are the narrow limit of radiating tube 1.Its length overall increases, but thin thickness, for slim.

Claims

1, a kind of HVAC heat abstractor, a kind of aluminium alloy radiator of extrusion modling particularly, it is by the water inlet on top (vapour) pipe 5, the radiating tube group 1 at middle part and the water outlet (vapour) of bottom pipe 6 assembly weldings form, water inlet (vapour) 5 and water outlet (vapour) pipe 6 that it is characterized in that this radiator are to be made by the heavy wall aluminium-alloy pipe of external diameter 27 or 33mm, the radiating tube group 1 at middle part is that the aluminium alloy gilled tube by extrusion modling constitutes, radiating tube 1 is vertically arranged, quantity and height can be set as required, after 6 combinations of pipe 5 pipes, form through argon arc welding or oxygen welding.

2, radiator according to claim 1 is characterized in that the profiled outline of radiating tube 1 is rectangle, and the centre is a garden pipe 2, it is used for the conducting heating agent, and fin 3 and fin 4 are arranged all around, and they are arranged in parallel, holohedral symmetry is used for to the air heat radiation, and this radiating tube is an extrusion modling.

3, radiator according to claim 1 and 2 is characterized in that the garden pipe 2 in the middle of the radiating tube 1 is that external diameter is the thick-walled pipe about 25mm, the fin around it, thickness is about 1mm, fin 3 externally has the shell effect concurrently, and it stretches out, receive in the end, form cavity volume, it is outwards heat radiation both, again inwardly heat radiation, fin 4 only dispels the heat in cavity volume therein.

4, radiator according to claim 1 is characterized in that when radiating tube 1 during with the combination of water-in and water-out (vapour) pipe two kinds of compound modes being arranged: a kind of is that the fin of radiating tube is managed vertical with Inlet and outlet water (vapour), at this moment, the total length of radiator, but thickness is the long limit of radiating tube 1, is thick type; Another kind is that the fin and the water-in and water-out (vapour) of radiating tube are managed in the same way, and end to end, the cavity volume sealing that fin 3 is formed, and the radiator of this kind structure, its thickness are the narrow limit of radiating tube, its length overall increases, but thin thickness, for slim.
