Abstract

The utility model discloses a non-annular-fin finned tube heating radiator, which is composed of an upper and a lower water inlet tubes, a finned tube, a both-side thread joint element and a sealing cushion. The utility model is structurally characterized in that the surface of the finned tube is provided with fins in a certain amount; the fins can form straight line shapes and can also form curved line shapes. Compared with the cast iron radiator commonly used in China, the finned tube in the structure saves the cast iron from 30 percents to 50 percents, and the heat working performance is increased greatly and simultaneously. When multiple finned tubes are required to be combined, both ends of the both-side thread joint element are added with the sealing cushions to carry out the combination. The surface of the combined radiator can also be easily cleaned to cause the radiator to be in good heat exchanging state regularly.

Description

Other than ring type rib gilled tube heating radiator

Belong to heating radiator tool technical field.

Up to now, the heating radiator that China uses, the overwhelming majority is a cast-iron radiator, and is especially all the more so at the cold district of China.The cast-iron radiator manufacturing process is fairly simple, and service life is long, price is also cheaper, still is widely used so far.But to consume metal more because of it, and volume is also relatively heavier, so to be again people do one's utmost wants the technical problem that solves for this.

In recent years, relevant both at home and abroad technical staff is actively making great efforts the various novel heating radiators of design, makes every effort to solve the weak point of existing heating radiator.

The purpose of this utility model is to solve and improve four technical problems: the one, solve the many problems of existing cast-iron radiator metal consumption; The 2nd, solve the not corrosion resistant problem of steel radiator; The 3rd, solve the problem that the spreader surface laying dust is difficult for removing; The 4th, improve the thermal property that has radiator now.

The utility model is shown in Figure of description, and main radiator portion is gilled tube [2], and gilled tube can be used casting, rolling or welding fabrication, and the fin on the gilled tube can be a linear, also can be shaped form.Gilled tube is connected with water inlet pipe and water outlet pipe [1] up and down, and each root gilled tube is an independently thermal component, according to the different needs of heating heat dissipation capacity, can make up with the gilled tube more than two, and the quantity of combination is fixed by the heat dissipation capacity that designing institute needs.The gilled tube combination adopts two-sided threaded connector [3] to be connected with sealing gasket [4].

The utility model is compared with the heating radiator that present China uses always, has several outstanding characteristics.The one, the cast-iron radiator that the utility model is more commonly used than China when area of dissipation is identical is saved metal (cast iron) can reach 30～50%; The 2nd, the utility model water capacity is less, and the radiator of " little " water capacity plays a part positive to energy-conservation heating; The 3rd, the cross-sectional area of the utility model water channel is less, and one of " improving the most promising measure of cast-iron radiator thermal property " is exactly " cross-sectional area that reduces water channel "; The 4th, the gap ratio of two gilled tubes of the utility model is bigger, can improve the thermal property of radiator, can clean spreader surface at an easy rate, to guarantee that radiator often is in good heat exchange state; The 5th, steel-molded if the utility model adopts, can adopt general watergas steel pipe manufacturing, so that be connected with heating line.

Most preferred embodiment:

Shown in Figure of description: other than ring type rib gilled tube heating radiator is mainly by water inlet pipe [1], gilled tube [2], two-sided threaded connector [3] and sealing gasket [4] four parts are formed up and down.Gilled tube is that the surface has 16 fins, and upper and lower side has the tube of water inlet pipe and water outlet pipe up and down, and fin is a linear, and whole gilled tube can (proportion be 7000Kg/m with casting pig ³) by the moulding of designed mould one-step casting, carry out the machining of coupling part behind the cleaning surfaces externally and internally, as the plane and the connecting thread of coupling part.During many gilled tube combinations, available two-sided threaded connector two ends add sealing gasket and make up.

Claims

1, a kind of other than ring type rib gilled tube heating radiator, it comprises water inlet pipe [1], gilled tube [2], two-sided threaded connector [3] and sealing gasket [4] up and down, there is fin on the surface that it is characterized in that gilled tube [2], water inlet pipe and water outlet pipe [1] is arranged up and down, during many gilled tube combinations, add the sealing gasket combination with two-sided threaded connector [3] two ends.

2, other than ring type rib gilled tube heating radiator according to claim 1 is characterized in that fin can be a linear, also can be shaped form.
