Abstract
The end face of the spiral heat exchange tube is composed of three sections of arcs 1 and an outer arc 6 in transition connection with the three sections of arcs, three spiral lines 2 are arranged in the radial direction of the spiral heat exchange tube to enable the spiral heat exchange tube to form an inner concave spiral surface 3 and an outer convex spiral surface 4 in the radial direction, and a straight head 9 is arranged at the inlet of the spiral heat exchange tube.
Description
The utility model relates to the spiral heat exchange tube technical field.
Existing shell-and-tube heat exchanger adopts the pipe of screw-type or straight tube outer wall recessing as heat exchanger tube, and the major defect of these two kinds of pipes is processing technology complexity, can't clear up after the inside pipe wall fouling, cause easily and scrap, or the heat exchange efficiency low consumption energy increases.
It is simple that the purpose of this utility model provides a kind of processing technology, and heat exchange area increases, the spiral heat exchange tube that the heat exchanger tube inwall is less scaling.
The utility model is achieved in that the spiral heat exchange tube end face is made up of the external arc 6 that three sections circular arcs 1 are connected with phase transition with it, and spiral heat exchange tube radially has three helixes 2 to make spiral heat exchange tube radially form indent helicoid 3 and evagination helicoid 4; Spiral heat exchange tube import department is a straight peen 9.
The utility model has the advantages that: processing technology is simple, and fluid media (medium) is not obstructed in pipe, and it is more smooth to flow, and is difficult for material stock and fouling, and heat exchange efficiency improves, and prolong service life.
Below in conjunction with accompanying drawing, the utility model is described further with embodiment:
Fig. 1 is a spiral heat exchange tube evagination helicoid schematic diagram; Fig. 2 is a spiral heat exchange tube indent helicoid cutaway view; Fig. 3 is the cutaway view of spiral heat exchange tube at Figure 1A-A place.
In the accompanying drawing, 1, circular arc, 2, helix, 3, the indent helicoid, 4, the evagination helicoid, 5, interior circular arc, 6, external arc, 7, the peak base, 8, caliber, 9, straight peen, 10, pitch.
This spiral heat exchange tube footpath 8 is of a size of 18-32mm, straight peen 9 is of a size of 50mm, peak base 7 is of a size of 2-5mm, interior circular arc 5 is of a size of 5-9mm, external arc 6 is of a size of 2-5mm, and pitch 10 is of a size of 90-150mm, and the lift angle of helix 2 is of a size of 10 °-16 °, according to above-mentioned size, on special equipment, can process this spiral heat exchange tube.
