Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a marine heat exchanger with a dual-channel design. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be categorized in various ways. Based on their operating process, they can be divided into three main types: partitioning, hybrid, and thermal storage (or regenerative). Based on their surface compactness, they can be divided into compact and non-compact types. Household heat exchangers solve the problem of collective heating in homes and hot water in winter. Their operating principle is the same as that of collective heating heat exchangers, differing only in size and style. Existing two-channel heat exchangers generally use welding for connection, which is time-consuming and labor-intensive to install, and inconvenient for maintenance and replacement, making it difficult for people to work. Furthermore, existing exchangers are generally straight-through, resulting in lower water temperatures in the center of the pipe, poor insulation, and uneven heat transfer.

[0024] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the fitting component includes a first positioning seat 7 installed on one side of the second clamp 5, a second positioning seat 8 is installed on one side of the first clamp 3, and a first rubber pad 9 is installed on the opposite surfaces of the second positioning seat 8 and the first positioning seat 7, and a pressure block 10 is installed at the bottom end of the second positioning seat 8. The top of the first positioning seat 7 is provided with a pressure groove that is slidably connected to the pressure block 10, and the interior of the two groups of first rubber pads 9 are provided with through holes corresponding to the pressure groove, and the interior of the first positioning seat 7 is provided with a mounting groove 11 on one side of the pressure groove, a first inclined surface 23 is provided on the top of one side of the pressure block 10, and a second inclined surface 22 is provided on one side of the pressure block 10 at one end of the first inclined surface 23, and the second rubber pad is embedded and installed on the side of the second clamp 5 close to the outer wall of the heat exchanger body 4. First, align the two groups of pressure blocks 10 with the pressure groove and clamp them in, so that the pressure block 10 and the positioning block 15 are partially in contact, completing the preliminary docking of the first clamp 3 and the second clamp 5.

[0025] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 The locking assembly includes a movable rod 14 installed and rotatably connected to the inner side of the mounting groove 11, a positioning block 15 is installed on the outer side of the movable rod 14, a third inclined surface 16 is provided at the bottom end of one side of the positioning block 15, and a fourth inclined surface 17 is provided at one end of the third inclined surface 16 on one side of the positioning block 15.

At the same time, the fixing spring 18 is also stretched, and the pressing block 10 is further pressed to move. The second cam 22 and the first cam 23 press the fifth cam 21 on the retraction plate 20, forcing it to retract to the inside of the retraction groove. After it aligns with the positioning groove, the torsion spring 25 rebounds and drives the retraction plate 20 to expand inside the positioning groove. At this time, the first rubber pad 9 and the second rubber pad are in a compressed state. After release, the first rubber pad 9 and the second rubber pad rebound a distance and the retraction plate 20 abuts against the inner wall of the positioning groove, thus completing the combined fixation. On the contrary, holding the knob and rotating it can drive the positioning block 15 to actively retract, so that the retraction plate 20 is away from the positioning groove.

A first spring 27 is installed between the two ends of one side of the extrusion plate 26 and the inner wall of the extrusion groove. A positioning hole extending to the inside of the positioning sleeve 6 is provided on the inner wall of the extrusion groove. A spring 27 is installed on one side of the extrusion plate 26 for snapping with the positioning hole. The positioning column 28 is connected, and one end of the extrusion plate 26 is rotatably connected to the pull ring 12. A hanging column 13 is installed on the outside of the base 1 below the pull ring 12. The cross-section of the hanging column 13 is L-shaped. Furthermore, the pull ring 12 is buckled to drive the extrusion plate 26 to retract. After the positioning column 28 is away from the inner side of the connecting groove, the pull ring 12 is deflected and hung on the hanging column 13. After one end of the positioning sleeve 6 is inserted into the inner side of the connecting groove, the pull ring 12 is released, and the positioning column 28 rebounds and is inserted into the inner side of the positioning hole to position the positioning sleeve 6.

[0027] The implementation principle of a dual-channel marine heat exchanger of the embodiment of the present application is as follows: align the two groups of pressing blocks 10 with the pressing grooves and insert them, so that the pressing blocks 10 and the positioning blocks 15 are partially in contact, completing the preliminary docking of the first clamp 3 and the second clamp 5, pressing downward, the first inclined surface 23 and the second inclined surface 22 are in contact with the third inclined surface 16 and the fourth inclined surface 17, so that the positioning block 15 cooperates with the limiting plate 24 and the limiting groove to expand around the movable rod 14, and the fixing spring 18 is also stretched at the same time, and the pressing block 10 is continued to be pressed to move, and the second inclined surface 22 and the first inclined surface 23 press the fifth inclined surface 21 on the retraction plate 20, forcing it to retract to the inside of the retraction groove. After it is aligned with the positioning groove, the torsion spring 25 rebounds and drives the retraction plate 2 0 is unfolded inside the positioning groove. At this time, the first rubber pad 9 and the second rubber pad are in a compressed state. After loosening, the first rubber pad 9 and the second rubber pad rebound for a distance and the retraction plate 20 abuts against the inner wall of the positioning groove, and the combined fixation is completed. Conversely, holding the knob and rotating it can drive the positioning block 15 to actively retract, so that the retraction plate 20 is away from the positioning groove. At this time, the pressing block 10 can be separated and disassembled to complete the disassembly, and the pull ring 12 is buckled to drive the extrusion plate 26 to retract. After the positioning column 28 is away from the inside of the connecting groove, the pull ring 12 is deflected and hung on the hanging column 13. After one end of the positioning sleeve 6 is inserted into the inside of the connecting groove, the pull ring 12 is released, and the positioning column 28 rebounds and is inserted into the inner side of the positioning hole to position the positioning sleeve 6.
