On the other hand, a kind of effect that stainless steel corrugated heat transfering pipe 2 of the invention is applicable not only to as shown in Figure 1 absorbs
Formula refrigeration machine, but also suitable for two kinds of effect Absorption Refrigerators.
In the following, stainless steel corrugated heat transfering pipe 2 is described in detail.
The material of stainless steel tube 4 can be STS200 series, STS300 series, STS400 series etc..It is preferred that stainless steel tube 4
Material for STS400 series.In particular, the material of stainless steel tube 4 can be the STS400 series 430J1L in STS400 series
(these STS 000 are serial or 000000 JIL of series of STS are the stainless steel classifying and numberings based on South Korea's KS standards).
Protuberance 6 can spirally be formed in stainless steel tube 4, alongst can be alternately configured in stainless steel tube 4
There are protuberance 6 and slot (groove) 7.Stainless steel tube 4 can improve the inside of stainless steel corrugated heat transfering pipe 2 by protuberance 6 and slot 7
Area of heat transfer.
The protuberance 6 and slot 7 of this specification are defined on the basis of the inside of stainless steel tube 4, and stainless steel tube 4 is used for shape
Lateral surface into the part of protuberance 6 can be outer side slot, and the lateral surface for being used to form the part of slot 7 is swelled for outside.
That is, the inner surface in stainless steel tube 4 can alongst alternately form protuberance 6 and slot 7, in stainless steel tube
4 outer surface can alongst alternately form outer side slot and outside protuberance.
Multiple fins 8 can protrude the outside heat for being formed in 4 outer surface of stainless steel tube to improve stainless steel corrugated heat transfering pipe 2 and pass
Pass area.
In stainless steel corrugated heat transfering pipe 2, as the height Hf of fin 8 and the height Hr of protuberance 6 are different, heat transmitting
It can also can be different.
The height Hr of protuberance 6 is an important factor for being affected to the heat transfer performance of stainless steel corrugated heat transfering pipe 2, preferably
Protuberance 6 has following height Hr, that is, compared with the non-corrugated heat transfering pipe of stainless steel with not forming protuberance, heat transfer performance can be improved,
It can be ensured that the durability of stainless steel corrugated heat transfering pipe 2 simultaneously.
In stainless steel corrugated heat transfering pipe 2 in the case where the height Hr of protuberance 6 is too small, raising heat may be used in and passed
The effect for passing performance is not perfect, in the case where the height Hr of protuberance 6 is too big, there may be tear phenomenon when forming protuberance 6,
It is preferred that stainless steel corrugated heat transfering pipe 2 is formed with the protuberance 6 of appropriate height Hr.
With the maximum internal radius MaxRi for the stainless steel tube 4 for being formed with fin 8 and protuberance 6 and maximum external half
Diameter MaxRo is different, and the height Hr for swelling 6 may be different.
Here, maximum internal radius MaxRi can be in the internal diameter from the central shaft O of stainless steel tube 4 to stainless steel tube 4
Maximum radius.
Also, maximum external radius MaxRo can be until the central shaft O to the end of fin 89 of stainless steel tube 4
Maximum radius in outer radius.That is, maximum external radius MaxRo can be maximum internal radius MaxRi, stainless steel tube 4

On the other hand, in the case where the height Hr of protuberance 6 is 0.7mm, stainless steel corrugated heat transfering pipe is because forming big height
Protuberance and part generates tear phenomenon, preferably swell and 6 be controlled as in appropriate altitude range.
Fig. 5 is the flow chart for the stainless steel corrugated heat transfering pipe manufacturing method for showing one embodiment of the present of invention, and Fig. 6 is to show
Go out the process chart of process manufactured by the stainless steel corrugated heat transfering pipe manufacturing method of one embodiment of the present of invention.
The stainless steel corrugated heat transfering pipe manufacturing method of one embodiment includes tubing step S1, fin machining step S2, wave
Line procedure of processing S3.
As shown in Figure 6A, it in tubing step S1, winds stainless steel plate body and the both side ends of stainless steel plate body is carried out
Solder joints, so as to form the stainless steel tube of hollow shape.The material of stainless steel plate body used when performing tubing step S1
Can be STS400 series, it is particularly possible to be STS400 series 430J1L.
When performing tubing step S1, stainless steel plate body can be wound as shown in figure 6 a, and to end 2A, 2B into
Row solder joints can make between stainless steel plate body passes through a pair of of pressure roll 101,102, on one side to add end 2A, 2B on one side
Pressure, to form the stainless steel tube 4 of hollow cylinder shape ".
Stainless steel tube 4 shown in Fig. 6 A " can have welded joint 5 long in its longitudinal direction, can be for wing
Piece is processed and is moved.
Fin machining step S2 can be performed after tubing step S1 is performed.In fin machining step S2, with the first roller
111st, 112 in stainless steel tube 4, and " peripheral surface forms multiple fins 8.
As shown in Figure 6B, jog 114 can be formed in the first roller 111,112, jog 114 can be in tubing step S1
" peripheral surface forms multiple fins 8 to the stainless steel tube 4 of formation.
In fin machining step S2, stainless steel tube 4 can be made on one side " by between a pair of first rolls 111,112, using on one side
Jog 114 forms fin 8.
Pass through the stainless steel tube 4 before a pair of first rolls 111,112 ", it can become after by a pair of first rolls 111,112
The stainless steel tube 4' of multiple fins 8 is shaped as, the stainless steel tube 4' detached with a pair of first rolls 111,112 can add for ripple
Work and move.
Corrugating processing step S3 can be performed after fin machining step S2 is performed.As shown in Figure 6 C, it is walked in corrugating processing
Corrugating processing is carried out in rapid S3, is pressurizeed with the second roller 121,122,123 from being formed with outside the stainless steel tube 4' of fin 8,
So as to protrude to form protuberance 6 continuous in the shape of a spiral in stainless steel tube 4' inner circumferentials.
