Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a coil heat exchanger. Background Art

[0002] Coil heat exchangers are generally divided into two types: external coil heat exchange and internal coil heat exchange. When internal coil heat exchange is used in related technologies, the coil may tilt due to factors such as fluid flow. Therefore, in order to ensure the normal operation of the heat exchanger, the coil needs to be supported by a supporting structure.

[0003] The Chinese patent with the announcement number CN214371969U discloses a spacing support and a coil heat exchanger thereof, wherein the spacing support comprises a connecting plate and a plug plate, one end of the plug plate is connected to the connecting plate, and a plurality of plug plates are arranged at intervals along the length direction of the connecting plate; both sides of the plug plate are provided with raised ribs. The spacing support is inserted into the gap of each circle of the spiral heat exchange coil, and each circle of the pipe is supported by the plug plate, and the spacing between the plug plates is the same as the spacing between two adjacent circles of the pipe; the raised ribs are arranged on both sides of the plug plate, which is conducive to enhancing the rigidity of the plug plate on the one hand, and on the other hand, the gap after the coil is coiled can be ensured according to the depth of the ribs.

[0004] Although the above technical solution supports each circle of pipes through the plug plate, during the actual operation of the coil heat exchanger, due to temperature changes, the internal medium and metal parts will expand and contract. If sufficient space is not reserved, it may cause extrusion, deformation or even damage to the internal parts of the heat exchanger, thereby affecting its normal operation and service life. During the vibration and thermal expansion and contraction of the coil, the plug plate in the above technical solution is squeezed between two adjacent circles of pipes, and cannot provide an appropriate amount of activity space for the pipes, which makes the coil easily squeezed and deformed, affecting the normal use of the coil.

[0005] Therefore, the art needs a coil heat exchanger to solve the above problems. Summary of the invention

[0006] The present invention provides a coil-type heat exchanger, aiming to solve the problem that the support method adopted for the coil in the coil heat exchanger in the related art cannot provide the coil with an appropriate amount of activity space when the coil expands or contracts or vibrates, causing the coil to be easily squeezed and deformed, thereby affecting the normal operation and service life of the coil.

[0007] A coil heat exchanger of the present invention comprises a shell, a coil disposed in the shell and a support mechanism, wherein the support mechanism comprises a support rod and a support block, the support rod is detachably connected to the shell, a plurality of mounting blocks are evenly arranged vertically on the support rod, and the number of the support blocks corresponds to the number of the mounting blocks;

[0008] The support block is U-shaped, including two side plates and a connecting plate connecting the two side plates, one of the side plates is fixedly connected to a rotating shaft, the rotating shaft sequentially passes through the corresponding mounting block and the support rod, and is connected to a handle, a support plate 1 is arranged between the two side plates, the support plate 1 is slidably connected to the two side plates, and is elastically connected to the connecting plate, and a support plate 2 is elastically connected to the side of the connecting plate away from the support plate 1;

[0009] When the support block is rotated until the side plate is in a horizontal state, the spacing between the upper and lower adjacent pipes of the coil is greater than the distance from the top surface to the bottom surface of the support block. When the support block is rotated until the side plate is in a vertical state, the pipes of the coil are located between the two side plates of the corresponding support block, support plate one is supported below its adjacent pipe, and support plate two is supported above its adjacent pipe.

[0010] The present invention provides a support rod and a support block. During installation, the support block is first rotated by a handle until its side plate is in a horizontal state. Then, the support rod is pushed so that the support block is located between two upper and lower adjacent pipes of the coil. Then, the support block is rotated again so that the side plates of the support block are in a vertical state. At this time, support plate 1 contacts the upper pipe, and support plate 2 contacts the lower pipe. Support plates 2 and 1 of the two upper and lower adjacent support blocks form elastic supports on the upper and lower sides of the pipe. The two side plates are located on both sides of the pipe to form protection on both sides of the pipe. When the coil is operating normally, support plates 1 and 2 provide stable support for the coil. When the coil expands and contracts due to heat and cold, support plates 1 and 2 follow the expansion and contraction of the coil to perform adaptive activities, thereby improving the situation where the coil is deformed due to strong squeezing.

[0011] Preferably, the support mechanism further comprises a support frame, the support frame is fixedly connected with an L-shaped support plate, the L-shaped support plate comprises a transverse portion and a vertical portion, the transverse portion is fixedly connected to the support frame, and a support space for placing the coil is formed between the vertical portion and the support frame;

[0013] The support block is located on one side of the support rod close to the vertical part of the L-shaped support plate, and a support structure is arranged between the support block and the vertical part. When the support rod moves until the support block is completely located in the support space, the support structure supports the support block.

[0014] By providing the support frame and the L-shaped support plate, on the one hand, the stability of the entire support mechanism can be improved, and on the other hand, both sides of the support block can be supported, ensuring the reliability of the support block supporting the coil.

[0016] Preferably, a slide groove 1 and a slide groove 2 extending vertically are provided in the support rod, the mounting block is vertically slidably connected in the slide groove 1, and adjacent mounting blocks are elastically connected, the mounting block located at the bottom is elastically connected to the bottom of the slide groove 1, the rotating shaft of the support block passes through the slide groove 2, and an adjusting screw is provided on the top of the slide groove 1, the top end of the adjusting screw passes through the support rod and extends to above the support rod, the bottom end is rotatably connected to the mounting block located at the top, and the adjusting screw is threadedly connected to the support rod.

[0017] By slidably connecting the mounting blocks with the support rods, the spacing between the mounting blocks is adjustable, that is, the spacing between the support blocks is adjustable to adapt to the support of coils of different specifications, thereby improving applicability.

[0018] Preferably, the support rod is provided with a slide groove three arranged parallel to the slide groove two, a transverse rack structure three is arranged at the position of the mounting block facing the slide groove three, a support bar is detachably connected in the slide groove three, a transverse rack structure four matched with the transverse rack structure three is arranged on the side of the support bar facing the mounting block, and when the transverse rack structure three is meshed with the transverse rack structure four, the support bar fixes the current position of the mounting block.

[0019] Preferably, a mounting frame is fixedly connected inside the shell, the mounting frame is formed with a U-shaped mounting groove extending vertically, and the support frame is installed in the U-shaped mounting groove.

[0020] Providing the mounting frame and the U-shaped mounting groove facilitates the rapid installation of the support frame and the coil in the shell, and the U-shaped mounting groove limits the movement of the support frame, thereby improving the stability of the support frame.

[0021] Preferably, the limiting structure includes screws arranged at vertical intervals, the screws are threadedly connected to the support frame, and penetrate into the U-shaped through groove to abut against the support rod.

[0023] By arranging the extrusion plate, the extrusion plate cooperates with the support plate 1 and the support plate 2 to form elastic support around the pipe of the coil, which not only provides a certain activity space for the coil when the coil expands and contracts due to heat, but also when the coil vibrates, the elastic parts between the extrusion plate and the side plate, and the springs between the support plate 1, the support plate 2 and the connecting plate can buffer the vibration of the coil. Moreover, due to the existence of the damping part, the extrusion plate, the support plate 1 and the support plate 2 will not form a large recoil on the coil, which is conducive to the coil to recover stability faster.

[0026] The beneficial effects of the present invention are as follows: the present invention forms elastic supports on the upper and lower sides of the pipeline through the support plate 2 and the support plate 1 of the two upper and lower adjacent support blocks, and forms protection on both sides of the pipeline through the two side plates located on the two sides of the pipeline. When the coil is operating normally, the support plate 1 and the support plate 2 stably support the coil. When the coil expands and contracts due to heat and cold, the support plate 1 and the support plate 2 follow the expansion and contraction of the coil to perform adaptive activities, thereby improving the situation where the coil is deformed due to strong squeezing, ensuring the normal operation of the coil, and extending the service life of the coil.

[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0044] like Figures 1 to 14 As shown, a coil heat exchanger of the present invention comprises a shell 1, a coil 2 arranged in the shell 1, and a supporting mechanism. The shell 1 is provided with an inlet and an outlet, and the coil 2 is connected to an external device that provides a heat exchange medium. A mounting frame 11 is fixedly connected to the shell 1, and the mounting frame 11 is formed with a U-shaped mounting groove 12 extending vertically. Two supporting mechanisms are symmetrically arranged on the coil 2, and the two supporting mechanisms are installed in the corresponding U-shaped mounting grooves 12. For the convenience of display, the attached Figure 3 Only the support mechanism on the right side of the coil 2 is shown.

[0045] like Figure 4 and Figure 5 As shown, the support mechanism includes a support frame 3, a support rod 4 and a support block 5. The support frame 3 is fixedly connected with an L-shaped support plate 6, and the L-shaped support plate 6 includes a transverse portion and a vertical portion, the transverse portion is fixedly connected to the support frame 3, and a support space for placing the coil 2 is formed between the vertical portion and the support frame 3. A U-shaped through groove 31 extending vertically is provided on one side of the support frame 3 facing the vertical portion, and the support rod 4 is located in the U-shaped through groove 31 and is slidably connected to the U-shaped through groove 31 in the horizontal direction.

[0046] The groove walls on both sides of the U-shaped groove 31 are provided with a limiting structure to limit the movement of the support rod 4, and the limiting structure includes screws 32 evenly arranged along the vertical interval, the screws 32 are threadedly connected to the support frame 3, and penetrate into the U-shaped groove 31 to abut against the support rod 4. When the support rod 4 moves to a suitable position relative to the U-shaped groove 31, the screws 32 are screwed so that the screws 32 are tightly against the support rod 4, so that the position of the support rod 4 is fixed.

[0047] like Figure 5 and Figure 6 As shown, a vertically extending slide groove 41 is provided on one side of the support rod 4 facing the vertical portion of the L-shaped support plate 6, and a plurality of mounting blocks 42 are evenly arranged vertically in the slide groove 41, and the mounting blocks 42 are vertically slidably connected to the slide groove 41. Adjacent mounting blocks 42 are connected by springs 43, and the mounting block 42 located at the bottom is connected to the bottom of the slide groove 41 by springs 43. An adjusting screw 44 is provided at the top of the slide groove 41, and the adjusting screw 44 is threadedly connected to the support rod 4. The top end of the adjusting screw 44 penetrates the support rod 4 and extends to the top of the support rod 4, and the bottom end is rotatably connected to the mounting block 42 located at the top.

[0048] When the spacing between the mounting blocks 42 needs to be adjusted, the adjusting screw 44 is screwed downward so that the adjusting screw 44 squeezes the mounting block 42 at the top to move downward, and the mounting block 42 at the top squeezes the other mounting blocks 42 to move synchronously through the spring 1 43, thereby reducing the distance between the two adjacent mounting blocks 42; or the adjusting screw 44 is screwed upward so that the mounting block 42 moves upward under the elastic force of the spring 1 43, thereby increasing the distance between the two adjacent mounting blocks 42 to accommodate coils 2 of different specifications.

[0049] like Figure 4 and Figure 7 As shown, the support block 5 is connected to the mounting block 42 correspondingly, and is arranged on one side of the mounting block 42 facing the vertical part of the L-shaped support plate 6. The support block 5 is U-shaped, including two side plates 51 and a connecting plate 52 connecting the two side plates 51. A support plate 1 53 is arranged between the two side plates 51, and the two ends of the support plate 1 53 are respectively slidably connected to the two side plates 51, and the support plate 1 53 is elastically connected to the connecting plate 52 through a spring 2 54. The two side plates 51 are respectively connected to an extrusion plate 55 through an elastic telescopic rod, and the extrusion plate 55 is located on the side of the support plate 1 53 away from the connecting plate 52. A guide plate 56 is arranged at one end of the extrusion plate 55 away from the support plate 1 53, and the guide plates 56 on the two extrusion plates 55 are arranged obliquely in a direction away from each other. A side of the connecting plate 52 away from the support plate 1 53 is connected to a support plate 2 57 through a spring 3 58, and a retractable sleeve rod 59 is connected between the support plate 2 57 and the connecting plate 52. The first support plate 53 and the second support plate 57 are both provided with arc-shaped transition surfaces 531 .

[0050] like Fig.13 and Fig.14 As shown, damping members are respectively connected between the support plate 1 53 and the support plate 2 57 and the connecting plate 52, and between the extrusion plate 55 and the corresponding side plate 51. Taking the damping member between the support plate 1 53 and the connecting plate 52 as an example, the damping member includes a damping rod 8 and a movable disk 81 fixedly connected to the damping rod 8. The movable disk 81 is provided with a plurality of through holes 82, wherein two through holes 82 are provided with movable plugs 83, and the movable plugs 83 are elastically connected to the movable disk 81 through an elastic structure. An accommodating chamber 84 is provided in the connecting plate 52, and the accommodating chamber 84 is filled with damping oil. The movable disk 81 is slidably arranged in the accommodating chamber 84, and the accommodating chamber 84 is divided into an upper chamber and a lower chamber. One end of the damping rod 8 is fixedly connected to the support plate 1 53, and the other end is slidably connected to the connecting plate 52.

[0051] When the support plate 1 53 is vibrated or squeezed by the coil 2 and moves downward, the damping rod 8 drives the movable plate 81 to move downward, and the damping oil in the lower chamber pushes open the movable plug 83 and enters the upper chamber through all the through holes 82. At this time, since all the through holes 82 can be opened, the movable plate 81 is subject to less resistance and is mainly subjected to the force of the spring 2 54, so that the spring 2 54 buffers the vibration of the coil 2. When the spring 2 54 wants to rebound, it will push the support plate 1 53 to drive the damping rod 8 and the movable plate 81 to move upward. The elastic structure between the movable plug 83 and the movable plate 81 and the damping oil in the upper chamber will cause the movable plug 83 to block part of the through holes 82, reducing the number of through holes 82 through which the damping oil can pass, thereby making the movable plate 81 subject to greater resistance and reducing the rebound force of the spring 2 54, avoiding the support plate 1 53 from forming a large recoil on the coil 2, which is conducive to the recovery of stability of the coil 2.

[0052] like Figure 7 , Figure 8 , Fig.11 and Fig.12 As shown, of the two side plates 51 of the support block 5, the side plate 51 close to the mounting block 42 is fixedly connected with a rotating shaft 50, and a second slide groove 45 is provided on the support rod 4. The rotating shaft 50 passes through the corresponding mounting block 42 and then passes through the second slide groove 45, and is fixedly connected with a handle 501. The handle 501 is fixedly connected with an indicator rod 1 502 and an indicator rod 2 503.

[0053] When the support block 5 is rotated to the side plate 51 in a horizontal state, the indicator rod 1 502 is in a vertical state, and the spacing between the upper and lower adjacent pipes of the coil 2 is greater than the distance from the top surface to the bottom surface of the support block 5, which facilitates the placement of the support block 5 between the upper and lower adjacent pipes; when the support block 5 is rotated to the side plate 51 in a vertical state, the indicator rod 2 503 is in a vertical state, and the pipe of the coil 2 is located between the two side plates 51 of the corresponding support block 5, the support plate 1 53 is supported below its adjacent pipe, and the support plate 2 57 is supported above its adjacent pipe.

[0054] like Figure 5 and Figure 7 As shown, a support structure is provided between the support block 5 and the vertical portion of the L-shaped support plate 6, and the support structure includes a first transverse rack structure 71 and a second transverse rack structure 61. The support block 5 is rotatably connected to a support column 7 on one side of the vertical portion of the L-shaped support plate 6, and the central axis of the support column 7 overlaps with the central axis of the rotation shaft 50 of the support block 5, the first transverse rack structure 71 is provided on one side of the support column 7 facing the vertical portion, and the second transverse rack structure 61 is provided on one side of the vertical portion of the L-shaped support plate 6 facing the support column 7.

[0055] When the support rod 4 moves toward the vertical part close to the L-shaped support plate 6, the support block 5 moves synchronously toward the direction close to the vertical part. When the transverse rack structure 1 71 on the support column 7 is engaged with the transverse rack structure 2 61 on the vertical part, the support block 5 is located in the support space, and the vertical part of the L-shaped support plate 6 supports the support block 5 through the cooperation of the transverse rack structure 2 61 and the transverse rack structure 1 71.

[0056] like Figure 8 , Fig.11 and Fig.12 As shown, the support rod 4 is provided with a slide groove 3 46 arranged parallel to the slide groove 2 45, and a transverse rack structure 3 47 is provided at the position of the mounting block 42 facing the slide groove 3 46. A support bar 48 is provided in the slide groove 3 46. When the support bar 48 is installed in the slide groove 3 46, the support bar 48 is completely fitted with the groove wall of the slide groove 3 46, and a mounting ear 49 is fixedly connected to the support bar 48. A transverse rack structure 4 (not shown in the figure) adapted to the transverse rack structure 3 47 is provided on the side of the support bar 48 facing the mounting block 42.

[0057] When the support bar 48 is installed in the slide groove three 46 and temporarily fixed by screws and mounting ears 49, the transverse rack structure three 47 is meshed with the transverse rack structure four, and the support bar 48 fixes the current position of the mounting block 42 and cooperates with the L-shaped support plate 6 and the support column 7 to form a stable support for the mounting block 42 and the support block 5.

[0058] The specific installation process of the coil of a coil-type heat exchanger of the present invention is as follows:

[0059] Before installation, the coil 2 is located outside the housing 1. First, the support rod 4 is moved along the support frame 3 until the support block 5 is completely located in the U-shaped through groove 31 to provide space for the placement of the coil 2. After the support mechanism is placed, the coil 2 is placed in the support space formed by the vertical part of the L-shaped support plate 6 and the support frame 3;

[0060] Twist the handle 501 to adjust the position of the support block 5 until its side plate 51 is in a horizontal state, then remove the support bar 48, cancel the fixation of the support bar 48 on the current position of the mounting block 42, and screw the adjusting screw 44 according to the spacing between adjacent pipes of the coil 2 to adjust the spacing between the mounting blocks 42 so that the support block 5 can smoothly enter between the adjacent pipes;

[0061] After the adjustment is completed, the support rod 4 is pushed toward the direction close to the coil 2, and the support rod 4 drives the support block 5 to enter the gap between the pipes of the coil 2. When the support column 7 on the support block 5 contacts the vertical part of the L-shaped support plate 6, the support rod 4 is stopped. At this time, the horizontal rack structure 1 71 on the support column 7 is meshed with the horizontal rack structure 2 61 on the vertical part;

[0062] Tighten the screws 32 on both sides of the support frame 3 so that the screws 32 are tightly pressed against the support rod 4 to fix the current position of the support rod 4;

[0063] The handle 501 is screwed to rotate the support block 5 relative to the support column 7 and the mounting block 42. During the rotation, the arcuate transition surfaces 531 on the support plate 1 53 and the support plate 2 57 contact the adjacent pipes, and the guide plate 56 on the extrusion plate 55 contacts the upper adjacent pipes to avoid scratching the pipes.

[0064] When the support block 5 is rotated to a position where its side plate 51 is in a vertical state, the support plate 1 53 is supported below the adjacent pipe, the support plate 2 57 is supported above the adjacent pipe, and the two extrusion plates 55 are against both sides of the pipe;

[0065] Install the support bar 48 in the slide groove 3 46, so that the transverse rack structure 4 on the support bar 48 is meshed with the transverse rack structure 3 47 on the mounting block 42, and then fix the support bar 48 by means of screws 32 and mounting ears 49, so as to cooperate with the support column 7 and the L-shaped support plate 6 to support the mounting block 42 and the support block 5, that is, to support the pipe of the coil 2;

[0066] Then, the coil 2 and the supporting mechanism installed on the coil 2 are installed together in the shell 1, so that the support frame 3 is inserted into the U-shaped installation groove 12 of the installation frame 11. The U-shaped installation groove 12 restricts the movement of the support frame 3, thereby realizing the installation of the coil 2.
