Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchanger that is easy to maintain. Background Technology

[0002] A heat exchanger is a device used to achieve heat exchange between two or more fluids. Its core function is to transfer heat from a high-temperature fluid to a low-temperature fluid through mechanisms such as heat conduction, convection, or radiation, thereby meeting the needs of heating, cooling, condensation, and evaporation in industrial production, energy utilization, or environmental control.

[0003] Traditional heat exchanger access panels are often installed using numerous bolts, which is cumbersome. For example, removing a single M16 bolt can take 30 seconds. This forces users to spend a considerable amount of time removing the access panel during heat exchanger maintenance, hindering efficiency and reducing maintenance effectiveness. Therefore, there is an urgent need for a heat exchanger with an easy-to-remove access panel. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat exchanger that is easy to maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat exchanger that is easy to maintain includes a heat exchanger body and a maintenance plate. The heat exchanger body has a maintenance groove, and a pad is fixedly installed on the inner wall of the maintenance groove. The maintenance plate is installed on the pad, and multiple mounting columns are fixedly installed on the maintenance plate. Each mounting column on the pad has a through hole corresponding to the mounting column. One end of each mounting column is rotatably provided with a limiting component, and the other end of each mounting column is movably provided with a pull plate. A locking column for locking the limiting component is fixedly installed on the pull plate.

[0007] In addition, in a preferred structure, each of the limiting members is fixedly provided with a connecting post, and each mounting post is adapted to have a through cavity corresponding to the connecting post. The other end of each connecting post is fixedly connected to the knob after passing through the through cavity.

[0008] Furthermore, in a preferred configuration, each knob has multiple spring cavities, and each spring cavity contains an outwardly mounted spring.

[0009] In addition, in a preferred configuration, the other end of each spring is connected to a pull plate, and locking posts are fixedly provided on both sides of the pull plate.

[0010] In addition, a preferred structure is that the mounting post has multiple locking cavities, each of which is adapted to the locking post, and the locking post is inserted into the locking cavity after passing through the pull plate.

[0011] Furthermore, in a preferred configuration, the mounting post and the limiting member are both adapted to the through hole, and the limiting member is locked to the inner wall of the pad after passing through the through hole.

[0012] The beneficial effects of this utility model are as follows: by setting the limiting part on the inner wall of the pad and locking it with the locking column, the inspection plate can be fixedly assembled in the inspection slot. This method of disassembling and assembling the inspection plate has a short operation time and is convenient for users to inspect the heat exchanger body. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-6A heat exchanger designed for easy maintenance includes a heat exchanger body 1 and a maintenance plate 2. The heat exchanger body 1 has a maintenance groove 11, and a pad 12 is fixedly installed on the inner wall of the maintenance groove 11. The maintenance plate 2 is mounted on the pad 12, and multiple mounting posts 3 are fixedly installed on the maintenance plate 2. Each mounting post 3 has a corresponding through hole 13 on the pad 12. One end of each mounting post 3 is rotatably equipped with a limiting element 4, and the other end of each mounting post 3 is movably equipped with a pull plate 5. A locking post 51 for locking the limiting element 4 is fixedly installed on the pull plate 5.

[0022] Each limiting member 4 is fixedly equipped with a connecting post 41, and each mounting post 3 has a corresponding through cavity for the connecting post 41. The other end of each connecting post 41 passes through the through cavity and is fixedly connected to the knob 42. The connecting post 41 connects the limiting member 4 and the knob 42 together, allowing the user to rotate the limiting member 4. Furthermore, the knob 42 is a flat knob, allowing the user to easily monitor the angle of the limiting member 4.

[0023] Each knob 42 has multiple spring cavities 421, and each spring 421 has a spring 422 installed outwardly inside. The other end of each spring 422 is connected to a pull plate 5, and locking pins 51 are fixedly installed on both sides of the pull plate 5. By using the elastic force of the spring 422, the pull plate 5 can be pulled towards the knob 42, so that the locking pins 51 can be stably positioned within the locking cavity 31.

[0024] The mounting post 3 has multiple locking cavities 31, each of which is adapted to the locking post 51, and the locking post 51 is inserted into the locking cavity 31 after passing through the pull plate 5.

[0025] Among them, the mounting post 3 and the limiting member 4 are both adapted to the through hole 13, and the limiting member 4 is locked to the inner wall of the pad 12 after passing through the through hole 13.

[0026] In this embodiment, the heat exchanger body 1 transfers heat between two or more fluids through heat conduction, convection, or radiation, achieving functions such as heating, cooling, condensation, or evaporation. Furthermore, during the production process, the maintenance slot 11 and maintenance plate 2 can be installed anywhere on the heat exchanger body 1 for easy maintenance by the user. It is worth noting that these are all prior art and not part of the technical problem of facilitating the disassembly and assembly of the maintenance plate 2 that this technical solution aims to address; therefore, they will not be elaborated upon in this utility model.

[0027] Furthermore, when the user needs to inspect the heat exchanger body 1, they only need to pull the pull plate 5 on the mounting column 3 outwards to release the mutual jamming between the locking column 51 and the locking cavity 31, and at this time the spring 422 is stretched. Then the user only needs to turn the knob 42 to drive the limiting member 4 to rotate until it is aligned with the mounting column 3, at which point the limiting member 4 is no longer jammed on the inner wall of the pad 12.

[0028] Finally, the user simply needs to loosen the pull plate 5, which will automatically reset due to the elastic force of the spring 422, causing the locking pin 51 to re-lock into the other locking cavities 31, thus fixing the rotated limiting member 4. Once all the limiting members 4 are rotated to align with the mounting pin 3, the inspection plate 2 can be removed. This method of removing the inspection plate 2 is convenient and facilitates maintenance of the heat exchanger body 1.

[0029] Furthermore, after the user has completed the maintenance of the heat exchanger body 1, he / she only needs to assemble the maintenance plate 2 on the pad 12, and make the mounting post 3 and the limiting member 4 on the maintenance plate 2 fit into the through hole 13. At this time, the limiting member 4 fits into the inner wall of the pad 12.

[0030] The user then simply pulls the pull plate 5 outwards again to release the interlock between the locking pin 51 and the locking cavity 31. Then, the knob 42 can be rotated to rotate the limiting member 4 again, locking it onto the inner wall of the pad 12. Finally, the pull plate 5 is released, and the knob 42 is fixed in place by the fitting between the locking pin 51 and the locking cavity 31, thus locking the limiting member 4. When all the limiting members 4 are rotated and locked onto the inner wall of the pad 12, the inspection plate 2 is securely installed.

[0031] Furthermore, when the limiting member 4 passes through the through hole 13, the limiting member 4 and the inner wall of the pad 12 are in adaptive contact. At this time, simply rotating the limiting member 4 will allow the limiting member 4 to be locked in the through hole 13.

[0032] Furthermore, the knob 42 is provided with two sets of locking chambers 31. When the limiting member 4 is locked against the inner wall of the pad 12, the locking pin 51 is aligned with one set of locking chambers 31. When the limiting member 4 is aligned with the mounting pin 3, the locking pin 51 is aligned with the other set of locking chambers 31. This prevents the limiting member 4 from rotating when it is not needed, thereby improving the user experience.

[0033] Furthermore, the knob 42 and pull plate 51 on the mounting column 3 are located on the outside of the inspection plate 2, so that the user can operate and adjust the knob 42 and pull plate 51.

[0034] In this utility model, by locking the limiting member 4 on the inner wall of the pad 12 and cooperating with the locking pin 51, the inspection plate 2 can be fixedly assembled in the inspection slot 11. This method of disassembling and assembling the inspection plate 2 has a short operation time and is convenient for users to inspect the heat exchanger body 1.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
