Abstract

The utility model discloses a novel pipe material, a cross section of a pipe body is provided with a petaloid structure, and the petaloid pipe body can be made into a spiral body structure. When used, the novel pipe material can greatly increase the contact area of the medium flowing in and out of the pipe material and the inner and the outer surfaces of the pipe material, and particularly the spiral body pipe materials also change flowing states of the medium in the pipe when heat exchange area is increased. Therefore, the utility model enhances heat exchange efficiency and can select different multiple-petal models so as to satisfy different requirements according to different applications, and the utility model has positive function to heat exchange applications.

Description

Novel tube

The utility model relates to a kind of medium transport tubing, particularly a kind of novel tube.

Present medium transport pipeline all is single and round tube, this tubing is in the medium transport process, though resistance loss is little, but because its heat exchange area is restricted, make heat-exchange capacity be subjected to very big influence in some application scenarios that need heat exchange.

The purpose of this utility model is that a kind of a kind of novel tube that increases heat exchange area, improves heat exchanger effectiveness is provided for the deficiency that solves above-mentioned technology.

In order to achieve the above object, a kind of novel tube that the utility model is designed, comprise pipe shaft, the cross section that it is characterized in that pipe shaft becomes the petal-shaped structure, this petal-shaped structure can be lobes two lobes or many, its pipe shaft can be a straight tube shape, can also be spirochetal, on production technology, can be directly by extrude, rolling, draw, casting or distortion draw moulding, this novel tube that the utility model is designed can be made of metal material, also can make of nonmetallic materials and composite thereof.

The resulting novel tube of the utility model, make inside and outside mobile medium of tubing and the inside and outside surface contact area of tubing obtain very big increase, conveyor screw tubing particularly, when increasing heat exchange area, also changed the flow regime of medium in the pipe, thereby greatly improved heat exchanger effectiveness, according to different application scenarios, can select different many lobes moulding satisfying different needs, this novel tube has very positive effect to the application scenario of need heat exchange.

Fig. 1 is five lobe modeling structure schematic diagrames;

Fig. 2 is two lobe moulding and becomes the leptospira structure schematic diagram;

Fig. 3 is three lobe moulding and the novel tube structural representation that is provided with enhancement Layer.

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1:

As shown in Figure 1, a kind of novel tube that present embodiment is described, it comprises pipe shaft 1, the cross section of its pipe shaft 1 becomes five flap petal design.Its production method can be to make by one drawing or extrusion molding.

Embodiment 2:

As shown in Figure 2, a kind of novel tube that present embodiment is described, the cross section of its pipe shaft 2 becomes two flap petal design, and 2 one-tenth leptospira structures of pipe shaft, and its production method is can twist drawing or pass through casting.

Embodiment 3:

As shown in Figure 3, a kind of novel tube that present embodiment is described, the cross section of its pipe shaft 3 becomes three flap petal design, its production method is at first metal to be drawn moulding, and then outside metal tube injection moulding heat-conducting plastic layer 4, heat-conducting plastic can adopt graphite, plastic hybrid, thereby obtains both had metal shielding 5, and the novel tube of good heat conductive performance and increase heat exchange area is arranged again.

Claims (2)

1, a kind of novel tube, it comprises pipe shaft (1), it is characterized in that the cross section of pipe shaft (1) becomes the petal-shaped structure.

2, a kind of novel tube according to claim 1 is characterized in that petal-shaped pipe shaft (1) becomes conveyor screw.
