Abstract
The utility model discloses a heat exchange tube which comprises a thin-walled tube body which is made of material with a good heat conducting property, wherein radial outer fins in longitudinal series are uniformly distributed on the outer wall of the tube body. The utility model is characterized in that the a longitudinal separating part is arranged in the tube body; the longitudinal separating part divides the tube body into two or more than two cavities. The utility model not only improves the heat exchange efficiency of the central medium of the tube but also increases the strength of a tube fitting when the tube fitting is bended and coiled; the bend property of the tube fitting is improved.
Description
The utility model relates to pipe fitting, and is specifically a kind of not only outside but also adopt the pipe fitting that increases the heat-transfer area structure in inside at pipe.
The heat exchanger pipe fitting that existing sealing is isolated comprises the heat exchange situation between gas-liquid, the gentle gas of liquid, and the pipe fitting of use is many with light pipe.For improving heat conductivility, Chinese patent 97212569.8 discloses a kind of follow-on heat-exchange tube, and it is provided with uniform radial vertically continuous outer fin on tube wall, also be provided with internal-rib at inboard wall of tube body.Though this heat-exchange tube increases, do not improve the heat exchange problem of the medium of tube hub aspect heat exchanger effectiveness at all.
The purpose of this utility model is that a kind of follow-on heat-exchange tube will be provided, and is intended to further improve the heat exchanger effectiveness of pipe fitting.
The purpose of this utility model is achieved in that heat-exchange tube, comprise that has the thin-walled body that good heat conductive performance material is made, described tube wall is provided with uniform radial vertically continuous outer fin, it is characterized in that also being provided with in the described body mediastinum, described mediastinum is separated into cavity more than 2 or 2 with body.
As further improvement of the utility model, described outer fin is along pipe outer wall coiled coil.
Be provided with the heat-exchange tube of mediastinum, the space in the body is separated into several chambers longitudinally, thereby has improved the heat exchanger effectiveness of tube hub medium greatly.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of another embodiment of the utility model.
Fig. 3 is the cross section view of the another embodiment of the utility model.
Fig. 4 is the utility model cross section view of an embodiment again.
Fig. 5 is the schematic diagram of the utility model coiled coil goods.
Fig. 6 is the schematic diagram of the utility model planar disk coiling product.
Figure 1 shows that the heat-exchange tube section bar, body 1 inwall is rounded, outer wall is provided with uniform radial vertically continuous outer fin 2, also be provided with cross star mediastinum 3 in the described body, described mediastinum is separated into four chambers with body, and like this, the thermograde in the pipe in the cross section of medium can be very little, heat exchange is abundant, and leaving water temperature is more even.
With reference to Fig. 2, described outer fin along pipe outer wall coiled coil, can further be increased heat exchange area.Described mediastinum cross section also can make other forms of star-like, as Samsung, five-pointed star, perhaps is designed to intersecting parallels, yi word pattern, perhaps steering wheel shape as shown in Figure 3.Described inboard wall of tube body also can be designed to square shown in Figure 4 or polygon according to different mediastinum forms.
Figure 5 shows that the individual layer spiral coil, is that above-mentioned heat-exchange tube section bar is made the manufactured goods that obtain after the helical form coiling.It is mainly used in liquid--the heat exchange (as the heat-exchange tube in the oil immersed type electric heater) between the liquid, and 5 are import, and 6 are outlet, and 4 is the coil pipe body.Can be coiled into the heat exchanger of multi-spiral formula equally by this method.
Figure 6 shows that the plane heat-exchange tube, it be with described heat-exchange tube section bar planar disk around after the manufactured goods that obtain.It can be used for liquid--the exchange heat between the gas, and as warmer, condenser etc.
Following table is a measured data of the present utility model:
| The electric heater volume | 15L | 30L | 50L |
| Heating power | 1500W | 2000W | 3000W |
