Abstract
The invention discloses the finned pipe device used for heat exchanger. The finned pipe comprises tube which has hollow circular cylinder forms and is used as channel of refrigerant, fin which is vertical to the tube, and support bracket which supports tube. The fin is on the surface of tube.
Description
Technical field
The present invention relates to be used for the finned tube device of heat exchanger.More specifically, the present invention relates to be used at heat exchanger, for example in evaporimeter and the condenser as the finned tube device of the passage that is used to transmit cold-producing medium.
Background technology
Usually, heat exchanger becomes cold-producing medium liquid and cold-producing medium is evaporated to gas from liquid from condensation of gas.That is to say that the gaseous refrigerant of the HTHP that heat exchanger will be discharged is condensed into liquid refrigerant from compressor, be used for heat is delivered to from gaseous refrigerant the air or the water of normal temperature.Perhaps, heat exchanger flashes to gaseous refrigerant with liquid refrigerant.Heat exchanger comprises finned tube, and this finned tube is as the passage that is used to transmit the cold-producing medium that refrigeration is provided.
The conventional tube that is used for heat exchanger is disclosed in Korean Utility Model No.95-29709.This conventional tube that is used for heat exchanger has adopted general structure shown in Figure 1.
With reference to figure 1, the conventional tube 10 that is used for heat exchanger comprises the fan (not shown) and as the pipe 20 of the passage that is used to transmit cold-producing medium.Pipe 20 is reeled with the form of cylinder.
Because manage 20 shapes that are wound into cylinder, so because of air longshore current Inbound A flows into and longshore current outgoing direction B formed air-flow character when flowing out, and heat exchanger effectiveness is reduced greatly.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of finned tube device that is used for heat exchanger, this finned tube device has improved coiling shape structure, and this structure provides bigger air contact area so that improve heat exchanger effectiveness.
According to an aspect of the present invention, provide a kind of finned tube device that is used for heat exchanger, this finned tube device comprises: pipe, and it has the form of hollow circuit cylinder, with as the passage that is used to transmit cold-producing medium; Fin, its cylinder direction with respect to described pipe vertically is formed on the outer surface of described pipe; And support, sandwich described pipe betwixt and be engaged with each other, to support described pipe, wherein, described fin is integrally formed on the outer surface of described pipe, and described fin is formed on the outer surface of described pipe with the form of spiral, and described pipe is repeatedly reeled and formed the shape of circular cone.
Description of drawings
Explain exemplary embodiment of the present invention below in conjunction with accompanying drawing, thereby be illustrated more clearly in above-mentioned and further feature and advantage of the present invention, wherein:
Fig. 1 shows the conventional tube that is used for heat exchanger;
Fig. 2 is the perspective view according to the finned tube device that is used for heat exchanger of the embodiment of the invention; And
Fig. 3 is the enlarged drawing of fin shown in Figure 2.
The specific embodiment
Illustrate in greater detail the finned tube device that is used for heat exchanger below in conjunction with accompanying drawing.
Fig. 2 is the perspective view according to the finned tube device that is used for heat exchanger of the embodiment of the invention.
With reference to figure 2, comprise according to the finned tube device that is used for heat exchanger 100 of present embodiment: pipe 112, it is as the passage that is used to transmit cold-producing medium; Fin 111, its cylinder direction with respect to pipe 112 vertically is formed on the outer surface of pipe 112; And support 120, between support 120, sandwich pipe 112 and be engaged with each other, with from inboard and lateral branch stay tube 112.
Fin 111 and pipe 112 whole manufacturings with formation finned tube 110, and preferably, finned tube 110 has the form of circular cone by the pipe 112 of repeatedly reeling circlewise.
120 pairs of finned tubes 110 of support support to keep the cone shape of finned tube 110.For finned tube 110 is supported, inner support 120 and support arm 120 are meshing with each other by sandwich pipe 112 between them.
Here, preferably, support 120 supports finned tube 110 three pre-positions, and the interval with 120 ° separates from the center of the winding form of finned tube 110 in described three precalculated positions.
Therefore, air flows into the coiling shape finned tube 110 from direction A has a larger-diameter side, and flows out from direction B by the opposite side that has in the coiling shape finned tube 110 than minor diameter.Because finned tube 110 is wound into cone shape, so finned tube 110 has bigger air contacting surface.Like this, can improve the heat exchanger effectiveness of finned tube 110.In addition, can fan be set, and also can change inflow direction and flow out direction in the inside of finned tube 110.
Fig. 3 is the enlarged drawing of fin shown in Figure 2.
With reference to figure 3, comprise finned tube 110 according to the finned tube device that is used for heat exchanger 100 of present embodiment, this finned tube 110 is made by form fin 111 on pipe 112.
Here, finned tube 110 comprises with spiral-shaped integral body and is formed at fin 111 on pipe 112 the excircle.Therefore, compare with the conventional tube that forms according to cylindrical shape, finned tube 110 has bigger air contacting surface.
Because the finned tube device that is used for heat exchanger 100 according to present embodiment forms like this, promptly by with aforesaid spiral-shaped on pipe 112 excircle the whole fin 111 that forms make, so, can form the finned tube device 100 of different shape like a cork.
As mentioned above, finned tube device according to the present invention has following advantage.
At first, have the cone shape that bigger air contacting surface is provided by finned tube device is formed, finned tube device of the present invention has heat exchanger effectiveness preferably.
Secondly, because fin and pipe integral body makes, so can be with the different shape manufacturing according to finned tube device of the present invention.Because do not need other fin manufacture process, so finned tube device according to the present invention has cost-effective advantage.
The application requires the foreign priority at the Korean Utility Model Application No.20-2005-0016531 of submission on June 9th, 2005, and its full content is incorporated this paper into by reference at this.
Though shown particularly and the present invention be described in conjunction with exemplary embodiment of the present invention, but, will be understood by those skilled in the art that, below not breaking away under the situation of the spirit and scope of the present invention that claims limited, can carry out change on various forms and the details to the present invention.
