Description

High efficient heat exchanging tube type heat exchangers

Technical field

The utility model relates to technical field of heat exchange equipment, especially relates to a kind of high efficient heat exchanging tube type heat exchangers.

Background technology

Heat exchanger extensive use in industrial multiple place, to a certain extent, the quality of heat exchanger exchange capability of heat, directly decides the height of industrial product quality.Heat-tube heat exchanger is one of heat exchanger types that frequency of utilization is the highest.As one of parts most important in such heat exchanger, the exchange capability of heat of heat exchanger tube directly decides the quality of the exchange capability of heat of heat exchanger.But although current used heat exchanger tube has fin with its heat radiation auxiliary, its maximum capacity do not given play to by many fins.

Summary of the invention

The purpose of this utility model is to provide a kind of high efficient heat exchanging tube type heat exchangers, and it has the splendid feature of exchange capability of heat.

The technical scheme that the utility model adopts is: high efficient heat exchanging tube type heat exchangers, comprise vertically arranged at least two heat exchanger tubes, the outer surface of every root heat exchanger tube is distributed with at least 2 fins from the top down successively, described each fin includes 4 outward extending Extendible flakes, 4 Extendible flakes being under the jurisdiction of same fin are distributed on the circumferential surface of heat exchanger tube uniformly, thus see from the top down, be under the jurisdiction of 4 Extendible flakes distribution in " X " shape of same fin, simultaneously, the height at the edge place, outside of all Extendible flakes is all lower than the height at edge place, inner side, and, the outer ledge of all Extendible flakes is equipped with the hook plate upwards extended.

Described Extendible flake is one-body molded with the hook plate be located thereon.

Be positioned at the downward projected area increasing or decreasing gradually of the fin on same heat exchanger tube.

For the downward projected area of the fin on adjacent two heat exchanger tubes, wherein one increases progressively gradually, another root successively decreases gradually.

The thermal conductivity factor being positioned at two fins adjacent on same heat exchanger tube is different.

The utility model is advantageously: exchange capability of heat is splendid.High efficient heat exchanging tube type heat exchangers of the present utility model has made improvement for the structure of fin and distribution.That is, the Extendible flake of fin distribution in " X " shape, increases the contact area of the media such as itself and outside air; Extendible flake is prepared as skewed, and hook plate is set, the speed of media flow and route are constantly changed.So, greatly improve the exchange capability of heat of heat exchanger tube, then directly enhance the exchange capability of heat of heat exchanger.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Fig. 1 be embodiment of the present utility model according to figure front sectional view;

Fig. 2 is the top view (fin is only shown) of a heat exchanger tube of the present utility model.

In figure:

10, heat exchanger tube;

20, fin, 21, Extendible flake, 22, hook plate.

Detailed description of the invention

Embodiment, is shown in shown in Fig. 1 and Fig. 2: high efficient heat exchanging tube type heat exchangers, comprises vertically arranged at least two heat exchanger tubes 10, and the outer surface of every root heat exchanger tube 10 is distributed with at least 2 fins 20 from the top down successively.The mode that fin 20 can be welded by intermediate frequency is fixed on corresponding heat exchanger tube 10.

Further say, each fin 20 includes 4 outward extending Extendible flakes 21,4 Extendible flakes 21 being under the jurisdiction of same fin 20 are distributed on the circumferential surface of heat exchanger tube 10 uniformly, thus see from the top down, are under the jurisdiction of 4 Extendible flakes 21 distribution in " X " shape of same fin 20.Meanwhile, the height at the edge place, outside of all Extendible flakes 21 is all lower than the height at edge place, inner side, and the outer ledge of all Extendible flakes 21 is equipped with the hook plate 22 upwards extended.That is, from vertical section, each Extendible flake 21 and the corresponding plate 22 that hooks thereof are in " 7 " font.Like this, add the contact area of fin 20 and medium, and the Extendible flake 21 of heeling condition change media flow route, hook plate 22 make the speed flowed during media for heat exchange create change, finally greatly add the exchange capability of heat of heat exchanger.

Continue to optimize:

Extendible flake 21 is one-body molded with the hook plate 22 be located thereon.Such as, a metallic plate is adopted to carry out bending rear formation.So, reduce preparation difficulty, and further increase exchange capability of heat.

Be positioned at the downward projected area increasing or decreasing gradually of the fin 20 on same heat exchanger tube 10.Meanwhile, for the downward projected area of the fin 20 on adjacent two heat exchanger tubes 10, wherein one increases progressively gradually, another root successively decreases gradually.Like this, by the continuous change of media flow speed, increase the exchange capability of heat of heat exchanger further.

The thermal conductivity factor being positioned at two fins 20 adjacent on same heat exchanger tube 10 is different.Such mode is the continuous change by media flow speed equally, increases the exchange capability of heat of heat exchanger further.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
