Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and particularly relates to a positioning component for a heat exchange tube. Background Art

[0002] As a new type of high-efficiency heat exchanger, the wound tube heat exchanger has many advantages such as compact structure, high heat transfer coefficient, and small leakage point. It has been well applied in many fields such as air separation units, large fertilizers, air separation, natural gas liquefaction, coal gasification, ethylene projects and hydrogenation units.

[0003] Existing spiral wound tube heat exchangers primarily consist of heat exchange tubes spirally wound around a central tube from the inside out, with gaskets used to position each layer of tubes. For information on existing gasket structures, please refer to the structures disclosed in utility model patents ZL201621015355.9, "A Heat Exchange Tube Gasket Structure" (authorization publication number CN205980909U), and ZL201320173135.9, "Specially Shaped Gaskets for Spiral Wound Tube Heat Exchangers" (authorization publication number CN203240942U).

[0004] Existing gaskets are generally suitable for the case where the winding angles of adjacent layers of heat exchange tubes are consistent. If the winding angles of adjacent layers of heat exchange tubes are different and the two are arranged at an angle, the existing gaskets are not suitable. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a positioning assembly for heat exchange tubes in view of the current status of the prior art, so as to be applicable to various winding angles of adjacent layers of heat exchange tubes.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a positioning assembly for heat exchange tubes, comprising:

[0007] A first pipe clamp having a first recess for matching with the outer peripheral wall of the first heat exchange pipe;

[0008] The second pipe clamp has a second recessed portion for matching with the outer peripheral wall of the second heat exchange pipe;

[0009] Its characteristics are:

[0010] A protrusion and a groove are selectively provided on the outer wall surface of the first recess and the outer wall surface of the second recess, respectively. The protrusion is rotatably engaged in the groove, so that the first pipe clamp and the second pipe clamp can be relatively rotatably constrained together.

[0011] In this way, the present invention can rotate the first tube clamp and the second tube clamp according to the winding angle between the adjacent first heat exchange tubes and the second heat exchange tubes to constrain the first heat exchange tubes and the second heat exchange tubes together.

[0012] To facilitate assembly of the pipe clamp and the heat exchange tube, preferably, both the first and second recesses are C-shaped, with the C-shaped openings allowing the corresponding heat exchange tubes to be inserted therein. During assembly, the heat exchange tubes are simply inserted into the pipe clamp through the C-shaped openings, which facilitates operation. The pipe clamp also effectively restrains the heat exchange tubes, preventing them from accidentally becoming dislodged.

[0013] Furthermore, the C-shaped opening of the first recess is oriented downward;

[0014] The second pipe hoop is located on the upper side of the first pipe hoop, and the C-shaped opening of the second recess faces upward;

[0015] The protrusion and the groove are selectively located at the top of the first pipe hoop and the bottom of the second pipe hoop respectively.

[0016] In order to adjust the angle, preferably, the protrusion is clamped in the clamping groove in a manner that it can rotate around an axis extending vertically from its center, so that the axial direction of the first pipe hoop is parallel to the axial direction of the second pipe hoop or is arranged at an angle.

[0017] Furthermore, the longitudinal cross-section of the protrusion is T-shaped, and the slot is a matching T-shaped slot. In this way, the protrusion and the slot can be better snapped together.

[0018] In order to be able to adjust the angle, it is also preferred that the protrusion is spherical, and correspondingly, the groove is a ball socket, so that the first pipe hoop and the second pipe hoop are connected in a ball joint.

[0019] Compared with the prior art, the present invention has the advantage that the present invention can rotate the first and second tube clamps according to the winding angle between adjacent first and second heat exchange tubes to constrain the first and second heat exchange tubes together.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] like Figure 1 、 2 FIG. 1 shows a preferred embodiment 1 of a positioning assembly for a heat exchange tube according to the present invention. The positioning assembly includes a first pipe clamp 1 and a second pipe clamp 2 .

[0027] The first pipe clamp 1 has a first recess 10 for matching with the outer peripheral wall of the first heat exchange tube 31. The first recess 10 is C-shaped, and the C-shaped opening is for the corresponding first heat exchange tube 31 to be inserted into the first recess 10. In this embodiment, Figure 1 As shown, the C-shaped opening of the first recess 10 faces downward.

[0028] The second pipe clamp 2 is located on the upper side of the first pipe clamp 1, and the second pipe clamp 2 has a second recess 20 for matching with the outer peripheral wall of the second heat exchange tube 32. The second recess 20 is C-shaped, with the C-shaped opening facing upward and allowing the corresponding second heat exchange tube 32 to be inserted into the second recess 20.

[0029] At the same time, if Figure 2 As shown, a protrusion 11 with a T-shaped longitudinal cross-section is provided on the top of the outer wall of the first recess 10, and a clamping groove 21 is provided on the bottom of the outer wall of the second recess 20. The clamping groove 21 is a T-shaped groove adapted to the protrusion 11, and the protrusion 11 is clamped in the clamping groove 21 in a manner that it can rotate around an axis 110 extending vertically from its center, so that the first pipe clamp 1 and the second pipe clamp 2 can be relatively rotatably constrained together so that the axial directions of the two are parallel or arranged at an angle, and when the axial directions of the two are parallel, the first and second heat exchange tubes constrained on the first and second pipe clamps are arranged in parallel; Figure 1 As shown, when the two axes are arranged at an angle, the first and second heat exchange tubes constrained on the first and second tube clamps are also arranged at an angle. Figure 1 The first heat exchange tube 31 extends left and right, and the second heat exchange tube 32 extends front and back, and the two are perpendicular to each other.

[0030] In this way, the positioning assembly of this embodiment can be used to position the first and second adjacent heat exchange tubes in the inner and outer layers, and the first pipe clamp 1 and the second pipe clamp 2 can be rotated according to the winding angle between the adjacent first and second heat exchange tubes to constrain the first heat exchange tube 31 and the second heat exchange tube 32 together.

[0031] At the same time, the vertical distance H between the bottom of the inner wall of the second recess 20 and the top of the inner wall of the first recess 10 is the interlayer spacing between adjacent first and second heat exchange tubes. Figure 2 .

[0032] Example 2:

[0033] like Figure 3 、 4 As shown, the preferred embodiment 2 of the positioning assembly for heat exchange tubes of the utility model is basically the same as the embodiment 1, except that in this embodiment, the protrusion 11 is spherical, and correspondingly, the groove 21 is a ball socket, so that the first pipe hoop 1 and the second pipe hoop 2 are connected by a ball joint.

[0034] In the specification and claims of the present invention, directional terms such as "front," "back," "up," "down," "left," "right," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the present invention. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
