Abstract

The utility model belongs to a heat exchange medium which is a heat exchange device for a large quantity of fluid. The utility model has the main purpose that under the condition that the heat dissipating quantity is decreased little, the processing manufacturability and the adaptability of the product are increased, the service life of the product are extended, and the maintenance is convenient. The utility model has the main structure that both ends of two pairs of sheet heads 1 and three cylindrical steel pipes 3 which are formed by stamping are correspondingly welded to form a single sheet, a plurality of single sheets are welded into a set of radiators in a corresponding series connection way, and through holes of the sheet heads 1 at both ends thereof are welded with four screw nuts 2. The product is mainly suitable for factories, institutions, hospitals, schools, household dwelling houses, etc.

Description

Steel-tube column radiator

The utility model relates to the heat-exchange apparatus that a kind of heat exchange medium is a kind of a large amount of fluids, is the steel pipe columnar radiators, comprises head 1, screw 2 and radiating tube 3.

In Chinese utility model patent communique, announced " flanging steel column radiator " product on September 16th, 1987, its objective is and improve cross-ventilation heat exchange effect, add and significantly penetrate area of dissipation, improve heat dissipation capacity.Its formation is: be welded into the monolithic radiator by 2 blocks of different sheet metals of width, again with its wide steel plate bending that goes out part, several monolithics serial connections form.Its weak point is: complex structure, and anufacturability is poor, and the frock of seriation is various, and fragile, and life of product is short, and maintainability is poor.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of steel pipe columnar radiators, it is reduced under the little condition in heat dissipation capacity, improve the applicability of product processing technique and use, reach simple in structure, easy to maintenance, water pressure resistance, long purpose of life-span.

The purpose of this utility model can reach by following measure: make 6 openings in two pairs of head 1 that steel plate is stamped to form and the two ends correspondence of three steel cylindrical tube 3 be welded into the monolithic radiating piece, is one group of radiator by several monolithic radiating pieces by the corresponding welding polyphone of the through hole in the head 1, at four screws 2 of the through hole of its two ends head 1 welding, use as connecting steam heating pipe.The a pair of head 1 that Combination Welding forms wherein have a fluid through-hole that circle is bigger, and the vertical one side of corresponding through-bore axis has three identical less fluid passages, and all the other are closing form everywhere.The specification of steel pipe 3 is 3/4 o'clock water gas pipe, and the specification of head 1 is the A3 steel or the 08F steel of thick δ=2.5 millimeter.

Advantage of the present utility model is:

1, simple in structure and firm, the metal thermal intensity height is convenient to maintenance, and sealing property is better.

2, water capacity is big, water pressure resistance, and better heat stability, steam heating and hot-water heating all can.

3, improved the life-span of product greatly, manufacturing, transportation and use all make things convenient for.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is the structure chart of facing of the present utility model.

Fig. 2 is the side view of Fig. 1.

Number in the figure is described as follows:

The 1-head that dispel the heat, 2-screw, the 3-steel pipe that dispels the heat.

The utility model is further described below in conjunction with accompanying drawing:

Referring to Fig. 1 and Fig. 2, selecting for use thick is 2.5 millimeters A3 steel plate, make head 1 by punching press, form with every pair of Combination Welding, three two ends with 3/4 o'clock long steel pipe are inserted respectively in 6 openings in two pairs of head 1, and the welding sealing is as monolithic, with 6 monolithics as one group, correspondence is arranged in together each other, through hole in the head 1 is linked to each other be welded one group, respectively weld a screw 2 in last 4 through holes, two ends, its screw thread is G, be convenient to connect the hot-water heating pipe, above-mentioned welding method can adopt electric welding or press arc-welding.

Claims

1, a kind of steel pipe columnar radiators, comprise head 1, screw 2 and radiating tube 3, it is characterized in that the two pairs of head 1 that steel plate is stamped to form and the two ends correspondence of three column type steel pipes 3 are welded into the monolithic radiating piece, be welded as one group of radiator by the corresponding series connection of 4～30 radiating pieces, at four screws 2 of the through hole of its two ends head 1 fluid welding.

2, steel pipe columnar radiators according to claim 1 is characterized in that: the head 1 by a pair of Combination Welding have a through hole, and the one side vertical with through hole has three identical circular opens side by side.

3, steel pipe columnar radiators according to claim 1 is characterized in that: the specification of steel pipe 3 is 3/4 o'clock a water gas pipe.

4, steel pipe columnar radiators according to claim 1 and 2 is characterized in that: head 1 be by thick be that 2.5 millimeters steel plate punching press combines.
