Abstract

The utility model belongs to indoor heating equipment in public buildings and civil buildings. The utility model is characterized in that the fin structural form of a full steel tube reinforced fin-and-column type heating radiator is changed, fins form rough and inconsecutive surface structure, thus the heat transmission performance of the fins is enhanced, and the heat dissipation capacity of the radiator is increased.

Description

Full steel tube reinforced fin-and-column type heating radiator

Title of the present utility model is " all steel pipe is strengthened rib column type heating radiator ", belongs to the indoor heating equipment of public building and civil buildings.

" all steel pipe rib column type heating radiator " (another patent of the inventor) of using has corrosion-resistant because of it now, in light weight, handsome in appearance, heat dissipation capacity is bigger, price is low and be widely used, but the fin of this radiator is ganoid straight rib, and generally only do rib in steel pipe water channel both sides, form air duct between the fin, when air is heated and rises along fin surface like this near laminar condition, therefore form the air flow boundary layer of a continous-stable on the fin surface, because this layer of air boundary layer heat transfer poor performance is so have certain influence to the heat-sinking capability of entire radiator.

The purpose of this utility model is development a kind of novel " all steel pipe is strengthened rib column type heating radiator ", reach the increase air agitation by the version that changes fin, destroy fin surface boundary layer of air, strengthen fin heat transfer, thereby improve the heat dissipation capacity of radiator.

The utility model is by taking such technical measures to realize goal of the invention, in the air duct that forms by fin, and the some fins of on the steel pipe water channel, burn-oning again, thus the distance between the change fin increases the fin area.The fin surface is stamped out some concavo-convex positions and bar seam, make smooth rib surface become coarse, discontinuous rib surface texture form, we claim this fin for strengthening rib.When heated air rises along this rib is surperficial, will produce strong disturbance like this, form turbulent flow, thereby make the boundary layer attenuation, and make the boundary layer produce tomography in many places, so just increased fin with the heat exchange between the air, thereby improved the heat dissipation capacity of entire radiator.

The utility model steel pipe header is whole, on header, leave the hole of boxing out of giving with the welding of steel pipe water channel, the steel pipe water channel can be two water channels or three water channels, an end bending or a bending two ends of at least one water channel wherein, and steel pipe water channel two ends are welded on giving of steel pipe header and box out on the hole.

Below by the embodiment accompanying drawing the utility model is done explanation:

Accompanying drawing 1 is a front view of the present utility model.

Accompanying drawing 2 is side views of the present utility model.

Accompanying drawing 3 is cutaway views of the present utility model.

1 is the whole header of steel pipe up and down in the accompanying drawing, the 2nd, and the steel pipe water channel, the 3rd, outside fin, the 4th, be made in the reinforcement fin in the air duct, the 5th, give the hole of boxing out on the steel pipe header.

In the present embodiment, on steel pipe water channel 2, be welded with 4 and strengthen fin 4, the form that becomes to stagger is arranged, on steel pipe water channel 2, also be welded with two outside fins 3, formed air duct between two outside fins, every sheet heat radiator has 3 steel pipe water channels, wherein 2 of both sides bending two ends, steel pipe water channel 2 two ends constitute " all steel pipe reinforcement rib column type heating radiator with giving hole 5 welding of boxing out on the steel pipe header.”

The utility model can all be made the reinforcement rib with all fins, also can only the fin of channel interior be made the reinforcement rib; Fin is not cooked to strengthen to handle and is belonged to the utility model scope yet.

Outside the exterior surface heat radiation, a part of cold air enters air duct from the bottom to the utility model when work, is heated gradually along the fin surface and rises, and discharge from passage top, so circulation.In air duct, air with steel pipe water channel 2, fin 3, strengthen between the fin 4 and carry out heat exchange make air produce violent disturbance owing to strengthen fin 4, and cut off boundary layer of air and make it discontinuous, thereby improved heat exchange efficiency greatly, increased heat dissipation capacity.

The utlity model has following advantages:

1, the utlity model has advantage corrosion-resistant, that the life-span is long, pressure-bearing is high, water resistance is little, in light weight, aesthetic in appearance.

2, the utility model has been owing to increased fin in air duct, thereby increased heat exchange area, owing to adopted the reinforcement rib, changed air flow condition again, improved heat exchange efficiency, therefore greatly improved the heat dissipation capacity of radiator.

Claims

1, a kind of steel pipe column type heating radiator, by steel pipe header up and down, the welding of steel pipe water channel constitutes.It is characterized in that being welded with on steel pipe water channel 2 outside fin 3 and inboard fin 4, the fin surface stamps out some concavo-convex positions and becomes coarse discontinuous surface texture form with gap-shaped.

2, by the described radiator of claim 1, it is characterized in that steel pipe water channel 2 can be 2 water channels or 3 water channels, wherein have a steel pipe water channel one end bending or bending two ends at least, the two ends of steel pipe water channel 2 are welded on giving of whole steel pipe header 1 and box out on the hole 5.

3, by the described radiator of claim 1, it is characterized in that all stamping out concavo-convex position and bar seam on all fin surfaces, also can only stamp out concavo-convex position and become coarse noncontinuous surface version with gap-shaped on inboard fin 4 surfaces.
