Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a heat exchanger that can be quickly disassembled and assembled. Background Technology

[0002] A heat exchanger is an engineered device that transfers heat from one fluid (liquid or gas) to another fluid; the two fluids are typically at different temperatures and do not mix, but rather exchange heat through solid walls (heat transfer surfaces).

[0003] A search of Chinese patent CN221099475U reveals a heat exchanger with multiple outlet heads, comprising a heat exchange core and multiple outlet heads. The heat exchange core includes a fluid inlet and a fluid outlet. The multiple outlet heads are fixedly mounted on the fluid inlet or outlet of the heat exchange core. Each head includes an internal cavity that is in sealed communication with the fluid inlet or outlet of the heat exchange core. Multiple outlet pipes are provided on the head to connect the interior and exterior of the head. Each outlet pipe is equipped with a closure device to determine whether it connects the interior and exterior of the head. This patent solves the problems of difficulty in replacing irregularly shaped outlet heat exchangers and long maintenance times for remanufacturing heat exchangers in the prior art. This invention provides a heat exchanger that can be quickly put into use for equipment using irregularly shaped heat exchangers that requires urgent replacement.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. Traditional heat exchangers are usually fixed in the shell by bolts or welding. Disassembly requires the use of special tools to gradually remove a large number of fasteners, which is time-consuming and easy to damage the components. Especially when maintaining, cleaning or replacing the internal heat exchange unit, the complicated disassembly and assembly process seriously restricts work efficiency and may cause a decrease in equipment accuracy due to vibration transmission. In addition, during the disassembly process, due to the narrow installation position, it is not convenient to move the disassembled heat exchanger out of the shell and it is not convenient to adjust the disassembly port. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat exchanger that can be quickly disassembled and assembled.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a heat exchanger that can be quickly disassembled and assembled, including a housing, a heat exchanger body slidably mounted on the inner side of the housing, a buffer mechanism being provided between the housing and the heat exchanger body, a rotating mechanism being provided on the housing, and a disassembly mechanism being provided on both the housing and the heat exchanger body.

[0008] The rotating mechanism includes a turntable fixedly mounted on the outer shell, a rotating block fixedly mounted on the turntable, a fixed disk rotatably mounted on the rotating block, and a snap-fit ​​assembly provided between the fixed disk and the turntable;

[0009] The disassembly mechanism includes a support assembly disposed on the outer shell, two insert shells are symmetrically disposed on the support assembly, a handle adapted to the two insert shells is fixedly installed on the heat exchanger body, and a fixing assembly is disposed between the support assembly and the two insert shells.

[0010] Furthermore, an inlet and an outlet are fixedly installed on the heat exchanger body.

[0011] Furthermore, the buffer mechanism includes two side shells symmetrically fixedly mounted on the outer shell.

[0012] Furthermore, two side frames that are symmetrically fixedly installed on the heat exchanger body and slidably connected to the side shell are provided. Each side frame is connected to a first spring, and a buffer plate is connected to the end of the first spring.

[0013] Furthermore, the snap-fit ​​assembly includes multiple snap-fit ​​holes formed on the turntable, and two second springs are connected to the fixed plate, with a snap-fit ​​block adapted to the snap-fit ​​hole at the end of each second spring.

[0014] Furthermore, the support assembly includes two frame plates symmetrically fixedly installed on the outer shell, each frame plate having two circular sleeves fixedly installed, and the inner wall of each circular sleeve being connected to a third spring, the end of which is connected to a telescopic rod fixed to the insert shell.

[0015] Furthermore, the fixing assembly includes two fixing plates fixedly installed on the two insert shells, and a fixing bolt is movably installed on each of the frame plates, and the frame plates are threadedly connected to the threaded positions on the fixing bolts, and the fixing bolts are rotatably connected to the fixing plates.

[0016] The above-described solution of this utility model has at least the following beneficial effects:

[0017] 1. In this utility model, by pulling and rotating the fixing bolt, the fixing bolt drives the insert shell to move through the fixing plate, and the fixing bolt is fixed by the thread action of the frame plate, so that the insert shell is separated from the handle. By pulling the handle, the heat exchanger body can be quickly moved out of the inner side of the shell without disassembling parts with various tools, thus enabling quick disassembly and assembly of the heat exchanger body.

[0018] 2. In this utility model, before disassembly, by moving the handle, the outer shell can be moved, and the outer shell can be rotated by the turntable to rotate the rotating block, so that the disassembly port of the outer shell is rotated to a suitable angle for disassembly. The second spring can use its own elasticity to support the locking block, so that the locking block is engaged with the locking hole at the appropriate position on the fixed plate, thereby facilitating the disassembly and installation of the heat exchanger body.

[0019] 3. In this utility model, when installing the heat exchanger body, the heat exchanger body is moved into the inner side of the outer shell by the handle, so that the heat exchanger body drives the side frame to move into the inner side of the side shell. The first spring can use its own elasticity to support the buffer plate, so that the buffer plate buffers the heat exchanger body by abutting against the inner wall of the side shell, thereby preventing large vibrations during the installation of the heat exchanger body and preventing damage to the heat exchanger body.

[0030] In this embodiment of the utility model, the inlet 3 is connected to an external conveying device, and the outlet 4 is connected to an external pipeline. When installing the heat exchanger body 2, the heat exchanger body 2 is moved into the inner side of the outer shell 1 by the handle 21, so that the heat exchanger body 2 drives the side frame 6 to move into the inner side of the side shell 5. The first spring 7 can use its own elasticity to support the buffer plate 8, so that the buffer plate 8 buffers the heat exchanger body 2 by abutting against the inner wall of the side shell 5, thereby preventing large vibrations during the installation of the heat exchanger body 2 and preventing damage to the heat exchanger body 2.

[0031] Figures 1 to 6 As shown, the rotating mechanism includes a turntable 9 fixedly mounted on the outer casing 1, a rotating block 10 fixedly mounted on the turntable 9, a fixed disk 11 rotatably mounted on the rotating block 10, and a snap-fit ​​assembly provided between the fixed disk 11 and the turntable 9. The snap-fit ​​assembly includes multiple snap holes opened on the turntable 9, and two second springs 12 are connected to the fixed disk 11. Each second spring 12 has a snap block 13 adapted to the snap hole at its end.

[0032] In this embodiment of the utility model, before disassembly, by moving the handle 21, the handle 21 can drive the outer shell 1 to move, so that the outer shell 1 drives the rotating block 10 to rotate through the turntable 9, and rotate the disassembly port of the outer shell 1 to a suitable angle for disassembly. The second spring 12 can use its own elasticity to support the locking block 13, so that the locking block 13 can be engaged with the locking hole at a suitable position on the fixing plate 11, thereby facilitating the disassembly and installation of the heat exchanger body 2.

[0033] Figures 1 to 6As shown, the easy-to-disassemble mechanism includes a support assembly mounted on the outer shell 1. Two insert shells 18 are symmetrically arranged on the support assembly.

[0036] Working principle: Before disassembly, by moving the handle 21, the outer shell 1 can be moved, and the outer shell 1 can be rotated by the turntable 9 to rotate the rotating block 10. The disassembly port of the outer shell 1 is rotated to a suitable angle for disassembly.
