Abstract

The utility model relates to a composite radiator, belonging to the heating facilities in industrial and civil constructions. The radiator is composed of an upper header, a lower header, a radiating tube and a radiating fin. The upper header, the lower header and the radiating tube of the radiator are copper or aluminum tubes. The radiating tube is welded with a circular fin, and the fin is provided with a flow guiding port for inducing air turbulence and breaking laminar boundary layer, and chimney effect is utilized to improve radiating effect. The radiator has the characteristics of high pressure bearing, large radiating area, corrosion prevention, large radiating quantity and high metal heat intensity, and can be used for steam and hot water in heating systems.

Description

Combined radiator

The utility model relates to the heating installation in industry and the civil buildings.

At present, the steel heating radiator with steel plate is made owing to punching stretch in manufacture process, changes the material internal structure, in use damages because of corrosion prematurely.Though the cast-iron radiator corrosion resistance and good, pressure-bearing is low, metal consumption is high, is not the developing direction for from now on.

The purpose of this utility model just provides a kind of in light weight, pressure-bearing is high, area of dissipation is big, metal thermal intensity is high combined radiator.

The utility model---combined radiator, radiating tube that is communicated with this upper and lower header by upper and lower header, two ends and the radiating fin that is welded on this radiating tube constitute.Said radiator header can be a copper pipe, is equipped with the hole equably on two sides of copper pipe, and radiating tube is communicated with it.Can be processed into screw buckle at its two ends, so that be connected with the heat source system pipe network.The material of radiating tube is copper material or aluminium, and wherein a kind of two ends of radiating tube are crooked.Said radiating fin is an ellipse garden shape pipe, and radiating tube is passed at the center, and its minor axis part welds together with radiating tube, and the radiating tube two ends are connected with preformed hole on the header respectively, constitute a radiator integral.

Description of drawings is as follows:

Fig. 1 is the utility model combined radiator structure front view.

Fig. 2 is the utility model combined radiator structure side view.

Fig. 3 is the cutaway view of the utility model combined radiator structure chart 2.

Wherein, 1 upper and

lower header

2,3 radiating tubes, 4 ellipse garden radiating fins, 5 air inlets

As follows below in conjunction with the embodiment of description of drawings and the course of work:

2. the utility model combined radiator is connected with radiating tube by a upper and lower header side 1., 3. radiating tube is connected with the upper and lower header of radiator opposite side 1., 4. radiating tube 2., 3. 4. weld together with the ellipse fin that looses is gone up at radiating fin, and 5. inside and outside both sides have air inlet.

The course of work of the utility model combined radiator is as follows:

When the hot water in the heating system or steam during by this radiator, radiating tube is with the heat transferred radiating fin, and radiating fin heats to indoor heat radiation with the form of cross-ventilation and heat loss through radiation.Constitute by upper and lower header, radiating tube, radiating fin in this composite heating radiator, rational in infrastructure, have good heat-radiation effect, adopt copper or aluminium in addition, the coefficient of heat conduction is higher than steel material, be welded on the fin ovalize on the radiating tube, utilize " stack effect ", accelerate air velocity, the air inlet of being opened in the fin both sides can bring out air turbulence, the breakable layer laminar boundary layer is strengthened the heat loss through convection effect.Again owing to take said structure and adopt copper or aluminium can realize purpose in light weight, that pressure-bearing is high, area of dissipation is big, heat dissipation metal intensity is high.

Claims

1, a kind of combined radiator is characterized in that, this combined radiator is made by copper or aluminium, and radiating tube that is communicated with this upper and lower header by upper and lower header and two ends and the fin that is welded on the radiating tube constitute;

2, the composite heating radiator according to claim 1 is put down in writing is characterized in that, said header is a copper pipe, and its two ends are the screw thread screw thread, so that be communicated with heat source system, is equipped with the hole equably on two sides of copper pipe, and radiating tube is connected on this hole.

3, according to claim 1,2 combined radiators of being put down in writing is characterized in that, said radiating fin is oval, and said radiating tube passes from this ellipse radiating fin center, and the minor axis part welds together with radiating tube; Both sides have air inlet inside and outside radiating fin.
