Description

Technical Field

[0001] This utility model relates to the field of finned heat exchanger technology, and in particular to a finned heat exchanger that is easy to assemble. Background Technology

[0002] A finned heat exchanger is a heat exchange device that increases the heat transfer area by adding fins to the surface of heat exchange tubes, thereby improving heat transfer efficiency. It is widely used in various industrial fields, such as petrochemicals, refrigeration and air conditioning, energy and environmental protection. A finned heat exchanger mainly consists of fins, tube bundles, and a frame. Fins are typically made of thin metal sheets, possessing good thermal conductivity and mechanical strength. The tube bundle consists of multiple tubes through which the medium requiring heat exchange flows. The frame supports and fixes the fins and tube bundle. Its working principle is to expand the heat exchange area through the fins, increasing the contact area for heat exchange, thereby improving heat exchange efficiency.

[0003] Currently, when assembling finned heat exchangers, finned tubes need to be inserted into frames on both sides and in the middle. The middle frame is usually a metal plate with holes that fit the finned tubes. After assembly, the two ends of the finned tubes are welded to the frame.

[0004] However, during the process of inserting the finned tube into the frame hole in the middle position, the finned tube is prone to fin collapse and tipping, which requires tools to correct it. This not only affects the heat exchange performance and quality of the finned tube, but also seriously reduces its assembly efficiency. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an easy-to-assemble finned heat exchanger. The assembly method differs from the traditional method of inserting finned tubes into holes, effectively preventing fin collapse or tipping during insertion. This significantly improves assembly efficiency, enhances the quality of the finned heat exchanger, and facilitates disassembly during maintenance.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: a finned heat exchanger that is easy to assemble, including multiple finned tubes, side support plates, inner support plates and protective cylinders. The multiple finned tubes are connected between two side support plates and are arranged at equal intervals. The inner support plate is located between two side support plates. Multiple protective cylinders are inserted at equal intervals on the inner support plate. The protective cylinders correspond one-to-one with the finned tubes. The finned tubes pass through the corresponding protective cylinders. The inner edge of the protective cylinder is rounded. The inner support plate is cut into multiple sub-support plates along the horizontal direction. Each row of protective cylinders is cut into two semi-cylinders. The multiple sub-support plates are installed and spliced ​​from bottom to top to form a complete inner support plate.

[0007] Furthermore, it also includes two clamping parts, two locking screws, and insertion holes. The two clamping parts are rotatably connected to both sides of the lowermost sub-support plate, and the two locking screws correspond one-to-one with the clamping parts. The locking screws are connected to the ends of the clamping parts. Insertion holes are provided on both sides of the uppermost sub-support plate, and the insertion holes cooperate with the locking screws.

[0008] Furthermore, it also includes multiple rows of sliding grooves, multiple sliding members, and docking holes. Each of the side support plates has multiple rows of sliding grooves, which cooperate with the finned tubes. Multiple sliding members are slidably connected in each sliding groove. Each sliding member corresponds to a finned tube. A docking hole is provided on the sliding member, which docks with the end of the finned tube. The sliding member can slide up and down slightly in the sliding groove.

[0009] Furthermore, it also includes guide clamps, with a guide clamp connected to the upper side of each of the sub-support plates, the guide clamps being used to clamp the upper sub-support plates.

[0010] Furthermore, it also includes a support, with a slot on the upper side of the support, and the lowermost sub-support plate is detachably connected to the slot.

[0011] The beneficial effects of this utility model are as follows: This utility model divides the inner support plate into multiple sub-support plates, which are assembled with the finned tubes from bottom to top during assembly. First, the lowest support plate is fixed on the ground, and the finned tubes are placed in the semi-cylinder in sequence. Then, the sub-support plates are connected and the finned tubes are placed in sequence from bottom to top until the top layer is assembled. This assembly method is different from the traditional method of inserting finned tubes into holes, which can effectively prevent the problem of fins collapsing or falling during the insertion process. It can effectively improve the assembly efficiency, improve the product quality of finned heat exchangers, and facilitate disassembly during maintenance. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1-6 As shown, this embodiment provides an easy-to-assemble finned heat exchanger, including multiple finned tubes 1, side support plates 2, inner support plates 3, and protective cylinders 31. The multiple finned tubes 1 are connected between two side support plates 2 and are arranged at equal intervals. The inner support plate 3 is located between two side support plates 2. Multiple protective cylinders 31 are inserted at equal intervals on the inner support plate 3. The protective cylinders 31 correspond one-to-one with the finned tubes 1. The finned tubes 1 pass through the corresponding protective cylinders 31. The inner edge of the protective cylinder 31 is rounded. The inner support plate 3 is cut into multiple sub-support plates 32 in the horizontal direction. Each row of protective cylinders 31 is cut into two semi-cylinders. The multiple sub-support plates 32 are installed and spliced ​​from bottom to top to form a complete inner support plate 3.

[0021] This utility model divides the inner support plate 3 into multiple sub-support plates 32, which are assembled with the finned tubes 1 sequentially from bottom to top. First, the lowest support plate 2 is fixed on the ground, and the finned tubes 1 are placed sequentially inside the semi-cylinder. Then, the sub-support plates 32 are connected and the finned tubes 1 are placed sequentially from bottom to top until the top layer is assembled. This assembly method is different from the traditional method of inserting the finned tubes 1 into the holes. It can effectively prevent the problem of fins collapsing or falling over during the insertion process, effectively improve the assembly efficiency, improve the product quality of the finned heat exchanger, and facilitate disassembly during maintenance. The rounded corners of the edges further prevent the fins from collapsing or falling over.

[0022] Specifically, it also includes two clamping parts 4, two locking screws 5 and insertion holes 6. The two clamping parts 4 are rotatably connected to both sides of the lowest sub-support plate 32. The two locking screws 5 correspond one-to-one with the clamping parts 4 and are connected to the ends of the clamping parts 4. Insertion holes 6 are provided on both sides of the highest sub-support plate 32 and the insertion holes 6 cooperate with the locking screws 5.

[0023] In the above embodiments, after the sub-support plates 32 are assembled from bottom to top, the rotating clamping member 4 stably splices all the sub-support plates 32 together, and then the locking screw 5 is turned into the insertion hole 6 to complete the stable assembly of the inner support plate 3. This method is convenient for assembly and disassembly.

[0024] Specifically, it also includes multiple rows of sliding grooves 7, multiple sliding parts 8, and docking holes 9. Multiple rows of sliding grooves 7 are provided on each side support plate 2. The sliding grooves 7 cooperate with the finned tubes 1. Multiple sliding parts 8 are slidably connected in each sliding groove 7. The sliding parts 8 correspond one-to-one with the finned tubes 1. The sliding parts 8 are provided with docking holes 9. The docking holes 9 are docked with the ends of the finned tubes 1. The sliding parts 8 can slide up and down slightly in the sliding grooves 7.

[0025] In the above embodiments, the traditional connection method between the side support plate 2 and the finned tube 1 is as follows: holes are made in the side support plate 2, and the end of the finned tube 1 is inserted into the holes for welding. The above method requires precise hole making in the side support plate 2, and misalignment is easy to occur when the end of the finned tube 1 is inserted into the holes. The sliding member 8 and the sliding groove 7 are set so that the sliding member 8 can move in the sliding groove 7, eliminating the need for extra alignment operations. The sliding member 8 can be sleeved on the end of the finned tube 1 through the docking hole 9, and then welding is performed, which further improves the assembly efficiency and quality.

[0026] Specifically, it also includes guide clamping blocks 10. Each sub-support plate 32 is connected to a guide clamping block 10 on its upper side. The guide clamping block 10 is used to clamp the upper sub-support plate 32.

[0027] In the above embodiments, the guide clamp 10 facilitates the quick docking of the upper sub-support plate 32 and the lower sub-support plate 32, further improving the overall stability of the inner support plate 3.

[0028] Specifically, it also includes a support 11, with a slot 12 on the upper side of the support 11, and the lowermost sub-support plate 32 is detachably connected to the slot 12.

[0029] In the above embodiments, the support 11 facilitates the placement of the lowest side sub-support plate 32.

[0030] The working principle of this utility model is as follows: First, select an appropriate number of inner support plates 3 according to the length of the finned tube 1. Since the finned tube 1 is relatively long, multiple inner support plates 3 can be used.

[0031] During assembly, place the base on the ground, insert the bottommost sub-support plate 32, i.e. the sub-support plate 32 with clamping piece 4, into the slot 12 of the base, and place the finned tubes 1 in the semi-cylinder one by one, so that the two ends of all the finned tubes 1 are flush. Then, insert the next sub-support plate 32 on the bottommost sub-support plate 32, and quickly connect the two sub-support plates 32 through the guide clamping block 10. Repeat the above operation until the top layer is connected. Then rotate the clamping piece 4 so that all the sub-support plates 32 are inside the clamping piece 4, and turn the locking screw 5 into the insertion hole 6 to lock it.

[0032] Next, assemble the side support plates 2 on both sides and connect the side support plates 2 to the end of the finned tube 1. This allows the sliding member 8 to move so that the docking hole 9 on the sliding member 8 can quickly connect with the end of the finned tube 1. Then, weld the sliding member 8 to the side support plate 2 and the docking hole 9 to the finned tube 1.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
