Abstract

The utility model relates to the technical field of heat radiation device, and discloses a convective heat radiator, which comprises an upper collecting box and a lower collecting box; the flowing channels of the upper and lower collecting boxes are made by metal tubes with an inner layer and an outer layer which joint together tightly; the two sides of the outer metal tube of the flowing channel is fixedly connected with two cylindrical radiation convective channels; the upper and lower ends of the channel fasten the corresponding dust proof cover provided with a plurality of radiation holes; a plurality of parallel radiation plates are connected with the outer metal tubes of the flowing channel. The utility model has the advantages of light weight, small volume, high loading capacity, beautiful appearance, high convective efficiency, and healthy use.

Description

A kind of convector radiator

Technical field

The utility model belongs to the heating radiating device technical field, relates in particular to a kind of convector radiator that is used for industry, civil buildings.

Background technology

Heating radiator is the indispensable equipment of heating system.Traditional cast-iron radiator is because its weight is big, pressure-bearing is low, produce cause seriously polluted, ornamental poor, just progressively in light weight by having, volume is little, pressure-bearing is high and the steel of good looking appearance or Aluminium Radiator substitute.The patent No. is that the utility model patent of z101267059.6 then discloses a kind of radiation and convection radiator, but the heat radiation runner that this radiator connects owing to the same lower collecting box is square and goes up lower open mouth, fin is radial, so inner dead space is more, easily accumulation dust and not easy to clean when stopping using, can stir up a cloud of dust the environmental sanitation in the space that is unfavorable for warming oneself when reusing.

The utility model content

The purpose of this utility model just provides a kind of convector radiator that overcomes the prior art defective.

The technical solution adopted in the utility model is: convector radiator comprises upper and lower header, the runner of the upper and lower header of connection that constitutes by the inside and outside bimetal pipe of combining closely, be fixedly connected with two cylindrical heat radiation convection channel in the both sides of described runner outer layer metal tube, the two ends up and down of this passage are snapped with corresponding sanitary cover, and are connected with the fin that several are parallel to each other outside the runner in passage on the metal tube.

Its additional technical feature is: have louvre on the described sanitary cover; Go up the runner of lower collecting box in the described convection channel for connection.

Radiation and convection radiator provided by the utility model is compared with prior art and is had the following advantages: be snapped with corresponding sanitary cover owing to be connected in the two ends of the heat radiation convection channel on the runner, and the heat radiation convection channel is a cylindrical shape, the fin that is fixed in the heat radiation convection channel becomes parallel shape, so with respect to prior art, its inner dead space is less, and lower sealing on the convection channel, portion can not form the phenomenon of dust deposit within it, even some dust are arranged, also be easier to cleaning, so have the use hygienic advantages.

Fig. 1 is the flow passage structure schematic diagram of convector radiator;

Fig. 2 is an a-a cutaway view among Fig. 1;

Fig. 3 is another kind of a-a cutaway view.

The specific embodiment

Be described further below in conjunction with the structure and the preferred forms of accompanying drawing a kind of convector radiator provided by the utility model.

As depicted in figs. 1 and 2, structural representation for a kind of convector radiator runner provided by the utility model, its structure comprises upper header 1, lower collecting box 2 and the runner 3 that is connected upper and lower header, runner 3 is made of inner layer metal pipe 31 of combining closely and outer layer metal tube 32, the both sides of outer layer metal tube 32 are fixedly connected with two cylindrical convection channel 4, be snapped with corresponding sanitary cover 6 at the two ends up and down of convection channel 4, be connected with the individual fin 5 that is parallel to each other of 2-5 on the runner outer layer metal tube 32 of convection channel 4 being positioned at.When heating, hot water flows in last

lower collecting box

1,2 and runner 3, and thermal energy transfer is given the cold air in the convection channel 4, and cold air is heated to rise and brings heat into convection channel 4 outer space, other cold air enters in the convection channel 4 from replenishing down simultaneously, thereby finishes the convection current of cold and hot air.Fin 5 is set in the convection channel 4 can strengthens the heat transmission speed, accelerate the convection current of air.As further improvement, on sanitary cover 6, have louvre 7, be easier to the circulation of air.In addition, in order to improve the radiating efficiency of radiator, can be designed to the runner 3 that lower collecting box in a plurality of connections that are parallel to each other is arranged as shown in Figure 3, and place convection channel 4.Flow velocity and the area of dissipation of going up hot water between the lower collecting box can be improved like this, the radiating efficiency of radiator can be improved greatly.

Claims

1, a kind of convector radiator, the runner of the upper and lower header of connection that comprises upper and lower header, constitutes by the inside and outside bimetal pipe of combining closely, it is characterized in that: be fixedly connected with two cylindrical heat radiation convection channel in the both sides of described runner outer layer metal tube, the two ends up and down of this passage are snapped with corresponding sanitary cover, and are connected with the fin that several are parallel to each other on the runner outer layer metal tube in passage.

2, a kind of convector radiator according to claim 1 is characterized in that: have louvre on the described sanitary cover.

3, a kind of convector radiator according to claim 1 is characterized in that: be fixed with the runner that the same lower collecting box connects in the described convection channel.
