Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger fin technology, and specifically relates to a fin structure for a ship heat exchanger. Background Technology

[0002] Marine heat exchangers typically employ corrugated, serrated, or porous fin designs to enhance fluid turbulence, disrupt the thermal boundary layer, and improve heat transfer efficiency. The fins are often made of aluminum alloy, titanium, or copper alloy to withstand corrosive environments such as seawater. Their compact layout significantly increases the heat transfer area per unit volume, resulting in smaller, lighter equipment that can accommodate various heat exchange requirements, including gas-liquid exchange.

[0003] However, the above structure still has some shortcomings. After long-term use, dust will accumulate on the surface of the exchanger fins, which requires regular cleaning. Because the overall exchanger fin structure is not easy to disassemble, the dust cleaning efficiency is reduced, and it is also not conducive to the user's later maintenance of the exchanger fins. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a finned structure for a marine heat exchanger to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

A protective plate is snapped onto one side of the heat exchanger body, and a first slot is formed on one side of the protective plate, extending into the interior of the heat exchanger body. A second slot is formed on the inner wall of the first slot, and a circular groove is formed on the inner side of the first slot. A first locking block is snapped onto the inner side of the first slot, and a second locking block that matches the second slot is fixedly connected to the outer side of the first locking block. The second locking block is snapped onto the inner side of the circular groove.

[0007] As a preferred technical solution, a retaining spring matching the second retaining block is installed on the inner side of the circular groove. The other side of the second retaining block is engaged with one side of the retaining spring. The second retaining block is engaged with the inner side of the circular groove by the retaining spring. A sealing block is fixedly connected to one side of the first retaining block. The sealing block covers one side of the first retaining groove. A protrusion is fixedly connected to one side of the sealing block. The protrusion has an arc-shaped corner. A handle is fixedly connected to one side of the protective plate. The position of the handle corresponds to the position of the sealing block.

[0008] As a preferred technical solution, a positioning groove is provided on one side of the heat exchanger body, and a positioning block that matches the positioning groove is fixedly connected to the other side of the protective plate, and the positioning block is snapped into the inside of the positioning groove.

[0009] As a preferred technical solution, a sealing ring is fixedly connected to one side of the heat exchanger body. The sealing ring has a thickness of five millimeters. The positioning block is located on the inner side close to the sealing ring. One side of the sealing ring is in contact with the other side of the protective plate. The sealing ring is made of rubber material.

[0010] As a preferred technical solution, the bottom end of the protective plate is threadedly connected to a base plate, and the bottom end of the base plate is fixedly connected to a support leg. The support leg is fixedly connected to the four sides near the corner of the bottom end of the base plate, and the position of the base plate corresponds to the position of the heat exchanger body.

[0011] As a preferred technical solution, the bottom end of the base plate is provided with a screw hole, the screw hole extends into the interior of the protective plate, the inner side of the screw hole is threaded with a bolt, the top end of the bolt is threaded into the interior of the protective plate through the screw hole, and the base plate is threaded to the bottom end of the protective plate through the bolt and the screw hole.

[0012] As a preferred technical solution, the outer wall of the heat exchanger body is coated with an anti-corrosion layer, the thickness of the anti-corrosion layer on the outer wall of the heat exchanger body is two millimeters, and the anti-corrosion layer on the outer wall of the heat exchanger body is made of epoxy resin material.

[0013] In summary, the present invention has the following main advantages:

[0014] Firstly, during use, the presence of the first locking block allows the second locking block to be inserted into the circular groove. Adjusting the second locking block to a non-corresponding angle with the second locking groove effectively engages the second locking block, preventing displacement of the protective plate and thus fixing its position. When the heat exchanger body needs to be disassembled later, first adjust the second locking block to a corresponding angle with the second locking groove, and then pull out the first locking block directly. This allows the protective plate structure to be disassembled, facilitating the disassembly and assembly of the heat exchanger body and making it easier for users to clean or maintain the heat exchanger body later.

[0015] Secondly, due to the presence of the positioning block, the insertion of the positioning block can pre-define the position of the protective plate, which not only improves the stability of the protective plate's position but also makes the first locking block more precise, thus preventing the first locking block from shifting. Its sealing ring can effectively seal the connection point of the protective plate, thereby achieving a good sealing and dustproof effect and effectively improving the service life of the heat exchanger body.
