[0002] Plate heat exchangers are a type of high-efficiency heat exchange equipment. They use multiple corrugated metal plates that are sealed together to form multiple flow channels to achieve heat transfer. They have advantages such as small size, high heat transfer efficiency, and easy disassembly and cleaning.

[0003] A search revealed Chinese Patent Publication No. CN222124062, which discloses a plate heat exchanger that facilitates quick assembly and disassembly. This invention relates to the field of heat exchanger technology and includes a first end plate, a second end plate, a cold flow plate, and a hot flow plate. A sliding rod is fixedly connected to the first end plate and slidably connected to the second end plate. Multiple first and second positioning frames are slidably connected to the sliding rod. A first positioning block is provided at the bottom inner side of each first positioning frame. A first positioning groove is formed at the bottom of the cold flow plate. A second positioning block is fixedly connected to the bottom inner side of each second positioning frame. A second positioning groove is formed at the bottom of the hot flow plate. Handles are fixedly connected to the tops of both the cold and hot flow plates.

Two positioning rods 16 are threadedly connected to the lower rear side of the outer plate 11 for cooperating with the installation of the cold flow plate 2 and the hot flow plate 3. The two positioning rods 16 pass through and are movably connected to the second outer plate 12. A positioning plate 21 is movably connected to the positioning rod 16 located on the left side, and a positioning plate 31 is movably connected to the positioning rod 16 located on the right side. A positioning block 161 is threadedly connected to the rear end of the positioning rod 16 for facilitating the installation and removal of the positioning rod 16.

[0036] Furthermore, a mounting rod 14 is threadedly connected to the rear side of the outer plate 11. The upper mounting slots 22, 32, and 71 are movably connected to the mounting rod 14. A mounting rod 15 is threadedly connected to the lower rear side of the outer plate 11. The lower mounting slots 22, 32, and 71 are movably connected to the mounting rod 15. The mounting rods 14 and 15 are used to cooperate with the installation of the cold flow plate 2 and the hot flow plate 3. The mounting rod 15 penetrates the mounting base 6. Furthermore, the two mounting rods are movably connected and used to facilitate the assembly and disassembly of the second mounting base 6. The first mounting rod 14 and the second mounting rod 15 are both connected to the second outer plate 12 through it. The first outer plate 11 and the second outer plate 12 are provided with slots 13 on the top, bottom, left, and right sides, which are used to facilitate the installation of the pull rod 4. The pull rod 4 is movably connected to the slots 13. The rear of the second mounting rod 15 is fixedly connected to a limit ring 151, which is used to limit the movement of the second mounting base 6. The rear end of the second mounting rod 15 is threadedly connected to a fixing sleeve 152, which is used to fix the second mounting base 6.

[0037] Working principle: When installing the cold flow plate 2 and the hot flow plate 3, firstly, pull the second outer plate 12 away from the first outer plate 11 to ensure sufficient space between the first outer plate 11 and the second outer plate 12 for the installation of the cold flow plate 2 and the hot flow plate 3. Then, the first positioning plate 21 at the bottom of the cold flow plate 2 is engaged with the positioning rod 16 on the left side, and the first mounting slot 22 at the bottom of the cold flow plate 2 is engaged with the second mounting rod 15, so that the first mounting slot 22 at the top of the cold flow plate 2 is engaged with the outside of the first mounting rod 14. Then, the hot flow plate 3 can be installed on the rear side of the cold flow plate 2. When installing the hot flow plate 3, the second positioning plate 31 at the bottom of the hot flow plate 3 is engaged with the positioning rod 16 on the right side, and the second mounting slot 32 at the bottom of the hot flow plate 3 is engaged with the second mounting rod 15, and the hot flow plate... The second mounting slot 32 at the top of the heat exchanger 3 is engaged with the first mounting rod 14, thus completing the installation of the heat exchanger 3. Then, the second cold flow plate 2 is installed on the rear side of the heat exchanger 3. The above operation is repeated until both the cold flow plate 2 and the heat exchanger 3 are installed. Then, the blind plate 7 is installed at the rear. When installing the blind plate 7, the third mounting slot 71 at the bottom of the blind plate 7 is engaged with the second mounting rod 15, and the third mounting slot 71 at the top of the blind plate 7 is engaged with the first mounting rod 14. Then, the second outer plate 12 is pressed against the first outer plate 11, thereby clamping the heat exchanger 3 and the cold flow plate 2 between the first outer plate 11 and the second outer plate 12. Then, the multiple tie rods 4 can be installed and fixed in the multiple slots 13 respectively, completing the fixation between the first outer plate 11 and the second outer plate 12, thus completing the installation of the heat exchanger.

[0038] To disassemble the heat exchanger, first remove the pull rod 4 from the slot 13, then pull the second outer plate 12 away from the first outer plate 11, and then remove the cold flow plate 2, hot flow plate 3, and blind plate 7 in sequence. If the outer frame 1 needs to be disassembled, the first mounting rod 14 or the second mounting rod 15 and the positioning rod 16 can be rotated as needed to remove them from the first outer plate 11 and the second outer plate 12. If the second mounting seat 6 needs to be removed from the second mounting rod 15, simply rotate the fixing sleeve 152 to disengage it from the second mounting rod 15, and then remove the second mounting seat 6.

[0039] 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.
