Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to aluminum alloy heat exchanger heads. Background Art

[0002] Aluminum alloy heat exchanger heads are a component of heat exchangers, typically used to seal both ends of the heat exchanger. The design and material selection of the heads are crucial to ensuring the performance, efficiency, and service life of the heat exchanger. Traditionally, the heads of vertical shell-and-tube heat exchangers are connected via flanges.

[0003] Utility model CN209069086U discloses a vertical shell-and-tube heat exchanger head, including a tube body. Tube sheets are installed at the top and bottom of the tube body. An upper connecting plate is installed at the top of the upper tube sheet, and an upper head is installed at the top of the upper connecting plate. An inlet is provided at the top of the upper head. A lower connecting plate is installed at the bottom of the lower tube sheet, and a lower head is installed at the bottom of the lower connecting plate. This vertical shell-and-tube heat exchanger head, by using a clamping plate, allows the clamping plate to be separated from the tube sheet by tightening the fixing bolts inside the clamping plate, thus releasing the restriction of the fixing block that slides and engages with the clamping plate. Then, removing the fixing block allows the upper head to be opened. By using a locking rod and tightening the fixing nut, the fixing nut is disengaged from the locking rod. Pulling the locking rod downwards allows the lower head to be separated from the tube body. This method facilitates disassembly and assembly by workers.

[0004] However, in the process of implementing the embodiments of the present invention, the inventors discovered that the background technology has at least the following defects: when disassembling the end cap in the above-mentioned utility model, it is still necessary to tighten the nut, which does not overcome the need to unscrew the nut when connecting the traditional flange, and there are still defects in disassembly efficiency. Therefore, we propose an aluminum alloy heat exchanger end cap to solve this problem. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 The aluminum alloy heat exchanger head includes a heat exchanger body 2 and two connecting ring edges 1. Head units 3 are fixedly installed on both sides of the heat exchanger body 2. The same sealing ring 4 is slidably sleeved on the outer side of the connecting ring edge 1 and the corresponding head unit 3. Two vertical holes are opened on the outer side of the sealing ring 4. A positioning plate 5 is vertically slidably installed in the vertical holes. The outer side of the connecting ring edge 1 and the head unit 3 is provided with a slot 17. The positioning plate 5 is movably engaged in the corresponding slot 17. A starting ring 8 is slidably installed on the outer side of the sealing ring 4. Two through holes are opened on the top of the starting ring 8. The same inclined plate 9 is fixedly installed between the inner walls of the left and right sides of the through holes. An inclined hole is opened on the left side of the positioning plate 5. The inclined plate 9 is slidably installed in the corresponding inclined hole.

[0024] It should be noted that the vertical movement of the positioning plate 5 is restricted by the cooperation of the starting ring 8 and the inclined plate 9. The starting ring 8 needs to move laterally to drive the positioning plate 5 to move vertically. This vertical angle limiting method greatly avoids the possibility of the positioning plate 5 becoming loose.

[0025] In this embodiment, two riveting plates are fixedly installed at the bottom of the starting ring 8, and two riveting grooves are opened on the outer side of the sealing ring 4. The riveting plates are slidably installed in the corresponding riveting grooves. The riveting plates and riveting grooves are designed to limit the starting ring 8 to move horizontally on the surface of the sealing ring 4.

[0026] like Figure 3 As shown, auxiliary grooves are provided on the sides of the two vertical holes that are far apart from each other, and inner plates 6 are fixedly installed on the sides of the two positioning plates 5 that are far apart from each other. The same return spring 7 is fixedly installed between the bottom of the inner plate 6 and the bottom inner wall of the corresponding auxiliary groove, which plays the role of limiting and guiding the positioning plate 5, so that the positioning plate 5 can only move in the vertical direction.

[0027] The top of the starting ring 8 has a square groove, and the bottom inner wall of the square groove has a sliding hole. A zigzag plate 10 is slidably installed in the sliding hole. A limit groove is opened on the outer side of the sealing ring 4. The zigzag plate 10 is movably engaged in the limit groove. The horizontal movement of the starting ring 8 is restricted by the cooperation between the zigzag plate 10 and the limit groove.

[0028] A rectangular edge 11 is fixedly sleeved on the outer side of the folded plate 10. Two support springs 12 are fixedly installed at the bottom of the rectangular edge 11, and the bottom end of the support springs 12 is fixedly connected to the bottom inner wall of the square groove.

[0029] Side baffles 13 are fixedly installed on the inner walls of both sides of the square groove, and the side baffles 13 cooperate with the rectangular side 11.

[0030] like Figure 4 As shown, a plurality of sealing ring grooves 4 are provided on one side of the end cap unit 3, and a plurality of sealing ring plates 4 are fixedly installed on one side of the connecting ring edge 1. The sealing ring plates 4 are adapted to the corresponding sealing ring grooves 4. A sealing sleeve 14 is fixedly installed on one side of the connecting ring edge 1. The sealing performance of the connection between the connecting ring edge 1 and the end cap unit 3 is improved by the cooperation of the sealing ring plates 4 and the sealing ring grooves 4. The sealing ring plates 4 and the sealing ring grooves 4 have the characteristics of riveting, which can also improve the stability of the connection between the two. The sealing sleeve 14 extends into the hole of the connecting ring edge 1 and fits against the inner wall of the hole, further improving the sealing performance of the connection between the two.

[0031] The working principle of this utility model is as follows: the positioning plate 5 and the slot 17 cooperate to fix the sealing ring 4, the connecting ring edge 1, and the end cap unit 3. The folded plate 10 and the limiting groove restrict the lateral movement of the starting ring 8, thereby improving the stability of the sealing ring 4 installation. By pulling the folded plate 10 upward, the folded plate 10 is disengaged from the limiting groove. Then, the folded plate 10 is moved to the right, thereby driving the starting ring 8 to move to the left. The starting ring 8 drives the positioning plate 5 upward through the cooperation of the inclined plate 9 and the inclined hole, so that the positioning plate 5 is disengaged from the slot 17, thereby releasing the fixed connection between the sealing ring 4, the connecting ring edge 1, and the end cap unit 3, thus facilitating the installation or disassembly of the sealing ring 4.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
