Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figures 1 to 5, a kind of support system of big coils heat exchanger heat-exchanging tube, including the He of inner cylinder 4 being arranged concentrically
Outer barrel 5, is fixedly connected with some supporting plates 2 of radial first supporting plate 1 and second between inner cylinder 4 and outer barrel 5.First support
The quantity of the supporting plate 2 of plate 1 and second is respectively eight, the lateral wall of the first supporting plate 1 and the second supporting plate 2 around inner cylinder 4
Uniformly it is arranged alternately.The supporting plate 2 of a number of first supporting plate 1 and second ensure that as heat exchanger tube 3 provides enough branch
Support, it is to avoid long heat exchanger tube 3 is in vacant state.After heat exchanger tube 3 alternately passes through the first supporting plate 1, the second supporting plate 2 successively
It is threadingly advanced around inner cylinder 4, the first supporting plate 1 is fixedly connected with heat exchanger tube 3, the second supporting plate 2 is with the activity of heat exchanger tube 3 even
Connect.Some circular holes 101 for being easy to heat exchanger tube 3 to pass through are provided with first supporting plate 1, circular hole 101 is uniform in the first supporting plate 1
Distribution.As being cased with sleeve pipe 6 on Fig. 4, with the heat exchanger tube 3 of the junction of the first supporting plate 1, the external diameter of sleeve pipe 6 is equal to the hole of circular hole 101
Footpath, the internal diameter of sleeve pipe 6 is equal to the external diameter of heat exchanger tube 3.Because sleeve pipe 6 is completely corresponding with the circular hole 101 in the first supporting plate 1, do not have
There is space, therefore the supporting plate 1 of part heat exchanger tube 3 and first is, without relative motion, to belong to fixed support, fixed support
Ensure heat exchanger tube 3 in the case of fluid scouring, with suitable rigidity and stability.
Such as Fig. 5, offer some equally distributed square holes 201 in the second supporting plate 2, the cross section of square hole 201 it is square
External diameter of the length of side more than heat exchanger tube 3, two madial walls of the square hole 201 on the length direction of the second supporting plate 2 and heat exchange
Card has fixture 7 respectively between pipe 3, and the end face that fixture 7 is abutted with square hole 201 is plane, and fixture 7 is abutted with heat exchanger tube 3
End face be circular arc concave surface.When heat exchanger tube 3 passes through the square hole 201 of the second supporting plate 2, will not directly contact square hole 201, resistance
Small, installation difficulty reduction, heat exchanger tube 3 wedges a fixture 7 respectively after passing through square hole 201 at the two ends of each square hole 201.Gu
Determine the length of side of the width less than square hole 201 of part 7, such heat exchanger tube 3 can drive fixture 7 along footpath in the case where being heated
Moved to direction, that is, realize moveable support, moveable support ensures that heat exchanger tube 3 has certain deformation empty in the case where being heated
Between, prevent stress excessive.
The invention is applied not only on deep bid heat exchange of heat pipe, can also be used in other similar spiral heat exchange tubes 3
In the occasion of support, such as petrochemical industry in coil exchanger and middle coil exchanger.Can be carried using the invention
The stability of heat exchanger high, improves device security and life-span.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
