Abstract

The utility model relates to a GB steel tube steel aluminum composite radiator which belongs to a steel aluminum composite radiator using the building steel tube(GB/T 3091-2001) as the main body and contains an upper and lower joining box(1), a standing box(2), and a heat dissipation wing(4), an internal thread buckle(3) as well as a fission steel shield(5). The utility model is characterized in that the upper and lower joining box(1) is made of building steel tubes with a diameter of GB 42 millimeters; while the standing box(2) is mode of building steel tubes with a diameter from GB 26.2 to 26.7 millimeters; and the aluminum alloy is adopted to make the heat dissipation wing sheet; and the steel tubes used for the standing box(2) are extruded and penetrated into an aluminum wing sheet cavity to form the excessive matching, thus effectively reducing the heat resistance and doing no any damage to the steel tubes; the two ends of the standing box(2) are respectively welded with the upper and lower joining box(1); while the joining box(1) is covered with the fission steel shield(5) or an integrated steel shield. The water passing part of the radiator is fully made of international building steel tubes with a service life period the same as the service life of the main tubes of the building; thus the service life is long and the corrosion proof capacity is strong without additionally corrosion prevention treatment; in addition, the heat dissipation quantity is large and the cost is low; the bearing pressure is above 2.0MPa; and the structure is simple and no pollution is generated. Therefore, the utility model is applied in the northern regions of relatively poor water quality, in particular to highrise buildings.

Description

GB steel pipe steel aluminium composite heating radiator

Affiliated technical field:

The utility model relates to a kind of heat sink arrangement of heating of house, especially can high efficiency and heat radiation and the steel aluminium composite heating radiator of long service life.

Background technology:

Along with the radiator prices of raw and semifnished materials constantly raise, there is following problem in the radiator on the market: 1, anti-corrosion type radiator (conventional steel aluminium composite heating radiator) in the mild steel, there is the blind area in interior preservative treatment, handle less than the place cause leaking, service life is not long; 2, copper aluminium replica radiator costs an arm and a leg; 3, the aluminium alloy type radiator is unsuitable for the relatively poor area of northern water quality and uses the water quality requirement height; 4, the steel radiating effect is relatively poor.

The utility model content:

In order to overcome the problem that existing radiator exists, the utility model provides a kind of radiator, and this radiator has not only reduced requirements in water quality, has reduced cost, has improved radiating effect, and has increased radiator service life significantly.

The technical scheme that its technical problem that solves the utility model adopts is: this kind GB steel aluminium combined column wing-type radiator, and select for use GB/T3091-2001 steel pipe for building to cross water section as radiator body, comprise lower collecting box, upright case.GB steel pipe characteristics for building: corrosion resistance is strong, reaches service life more than 20 years, so need not to do interior preservative treatment, reduces the link and pollutes and can save processing cost; Be easy to buy, the cost of raw material is low.This radiator adopts the column type aluminium fin that has mesopore to do radiating fin, and mesopore internal diameter and upright case outer diameter of steel pipes interference fit effectively reduce thermal resistance, and heat flow rate per unit area is big.

The beneficial effects of the utility model are that heat dissipation capacity is big; With the building same life-span of body trunk line, durable in use; Corrosion resistance is strong, need not to do interior preservative treatment, and environmental protection meets specific (special) requirements such as the northern area of China cold weather, heating time length, water quality inferiority.Attractive in appearance, light, be easy to install, simple in structure pollution-free.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a GB steel pipe steel aluminium composite heating radiator outline drawing.

Fig. 2 is a GB steel pipe steel aluminium composite heating radiator split steel cage profile schematic diagram.

Lower collecting box on 1. among the figure, 2. upright case, 3. in screw thread, 4. aluminum alloy fin, 5. split steel cage.

The specific embodiment:

Be to make lower collecting box (1) in Fig. 1 with GB Φ 42mm steel pipe, make upright case (2) with GB Φ 26.4～26.9mm steel pipe, be expressed to upright case steel pipe in the cavity of aluminium fin (4) with machine, the cavity internal diameter of aluminium fin is than the little 0.3～0.5mm of outer diameter of steel pipes, make it interference fit, reduce thermal resistance, again the two ends of upright case are welded with last lower collecting box respectively, on last lower collecting box, buckle the split steel cage.

Claims (2)

1, a kind of GB steel pipe steel aluminium composite heating radiator, comprise upper and lower header (1), upright case (2), heat radiation wing (4), interior screw thread (3) and split steel cage (5), it is characterized in that: above-mentioned radiator is walked water section and is all adopted GB steel pipe for building, and described upward lower collecting box steel pipe is a GB Φ 42mm steel pipe for building, and described upright case steel pipe is GB Φ 26.2～26.7mm steel pipe.

2, GB steel pipe steel aluminium composite heating radiator according to claim 1 is characterized in that: do radiating fin with aluminium alloy, the upright used steel pipe of case penetrates in the aluminium fin cavity by extruding, forms interference fit with it.
