[0002] A cooler is a device widely used in multiple industrial fields such as chemical industry, petroleum, power, food, etc. It is used for heat exchange between fluids at different temperatures to meet specific process requirements. According to the heat transfer principle, it can be divided into a shell-and-tube cooler, a mixing cooler, and a regenerative cooler. The shell-and-tube cooler is the most common type, and among them, the tube-shell cooler and the plate cooler are the most widely used. As a key device for realizing heat exchange, the cooler has a very wide and important application in industrial production. Through continuous technological innovation and optimized design, the cooler will play a more important role in improving energy utilization efficiency and reducing operating costs.

[0003] In the prior art, a cooler is composed of various components, including a cooling tube bundle, a partition plate, an end cover, etc. Among them, the cooling tube bundle is the core heat exchange component, and the partition plate plays a role in distributing fluids and enhancing the heat exchange effect. When maintaining the cooler, if the internal structure, especially the cooling tube bundle, needs to be inspected, cleaned, or replaced, the partition plate usually needs to be removed to facilitate the operation.

[0004] However, the partition plate is mostly a complete structure sleeved on the cooling tube bundle. When the staff disassembles and assembles the partition plate, it is necessary to remove the partition plate from the cooling tube bundle one by one, which is rather cumbersome and affects the maintenance efficiency of the staff for the cooler.

Specific embodiments

[0023] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an efficient energy-saving cooler convenient for maintenance, including: a plurality of partition plates 5, in which a plurality of uniformly distributed heat exchange tubes 3 are installed; a plurality of sets of quick-disassembly and assembly mechanisms 7, each set of quick-disassembly and assembly mechanisms 7 is respectively arranged on the surface of the partition plate 5, and each set of quick-disassembly and assembly mechanisms 7 includes a mounting seat 701, the mounting seats 701 are symmetrically and fixedly installed on the surface of the partition plate 5 and each mounting seat 701 is in the shape of two semi-circular arcs, an activity groove 706 is opened in the middle of each mounting seat 701, a limiting block 705 is rotatably installed in each activity groove 706, a limiting groove 703 is symmetrically opened on the surface of each mounting seat 701, and a plurality of uniformly distributed limiting holes 702 are opened in each limiting groove 703. An auxiliary handle 707 is fixedly installed on the outer circumference of each limiting block 705, and each group of auxiliary handles 707 is symmetrically distributed along the mounting seat 701 in a central symmetry manner. An activity rod 7013 is slidably installed in the middle of each auxiliary handle 707, a spring 7012 is sleeved on the outer circumference of each activity rod 7013, a mounting plate 704 is fixedly installed at the end of each activity rod 7013, and a limiting pin 708 is fixedly installed on one side of each mounting plate 704 close to the activity rod 7013. Since the partition plate 5 is composed of a plurality of modules cooperating with the quick-disassembly and assembly mechanism 7, when maintenance is carried out, only the mounting plate 704 needs to be pulled. At this time, the limiting pin 708 will disengage from the limiting hole 702. At the same time, the spring 7012 is stretched. Then, the auxiliary handle 707 is rotated in the opposite direction. At this time, the limiting block 705 will rotate in the activity groove 706 until the limiting block 705 is reset in the corresponding mounting seat 701. Thus, the limit between each spliced partition plate 5 can be released. At this time, the staff can remove the partition plate 5 from the heat exchange tube 3, which is convenient for maintaining the heat exchange tube 3. When the partition plate 5 is spliced, the auxiliary handle 707 is rotated again. At this time, the limiting block 705 will rotate into the corresponding mounting seat 701. With the cooperation of the spring 7012, the limiting pin 708 will be inserted into the limiting hole 702. At this time, a plurality of modules form a complete partition plate 5, thus completing the quick installation of the partition plate 5 and not affecting the normal operation of the heat exchanger.

[0025] Guide blocks 709 are symmetrically and fixedly installed in each activity groove 706. Guide grooves 7011 are opened on the surface of each limiting block 705, and the guide blocks 709 are respectively slidably installed in the guide grooves 7011 on the same side. A plurality of uniformly distributed balls 7010 are embedded in each guide groove 7011. By providing the guide blocks 709 and the guide grooves 7011, when the limiting block 705 rotates, the guide block 709 will move in the guide groove 7011. Thus, the stability of the limiting block 705 during rotation can be increased. And, with the cooperation of the balls 7010 in the guide groove 7011, the smoothness of the movement of the limiting block 705 can be increased. One end of each spring 7012 is respectively fixedly installed on the auxiliary handle 707 on the same side, and the other end of each spring 7012 is respectively fixedly installed on one side of the mounting plate 704 on the same side close to the activity rod 7013. A baffle is fixedly installed at the end of each activity rod 7013 away from the mounting plate 704.

[0026] A tube sheet 1 is installed on one side of the heat exchange tube 3, and a plurality of uniformly distributed hole grooves 2 are formed on the surface of the tube sheet 1. The other side of the heat exchange tube 3 is U-shaped, and gaskets 6 are arranged between adjacent heat exchange tubes 3. By providing the gaskets 6, since the gaskets 6 are made of elastic materials, it can assist the staff to snap the gaskets 6 at the U-shaped positions of the heat exchange tubes 3, increasing the stability of the heat exchange tubes 3 during use. A plurality of uniformly distributed fixing bolts 4 are installed at the outer peripheral edge of the partition plate 5.

[0027] During actual use, the staff detaches the limit pin 708 from the limit hole 702 by using the mounting plate 704. At this time, the auxiliary handle 707 is rotated, and then the limit block 705 will rotate along the movable groove 706 into the same mounting seat 701. Then each splicing module will be separated, facilitating the staff to remove the partition plate 5 from the heat exchange tube 3 for maintenance and repair of the heat exchange tube 3. Moreover, a complete mounting hole is formed after splicing between each partition plate 5 module, facilitating the installation of the heat exchange tube 3. After the maintenance is completed, the limit block 705 is rotated again until the limit block 705 is snapped into the mounting seat 701, and the spring 7012 will snap the limit pin 708 back into the limit hole 702, thus completing the installation of the partition plate 5 and improving the maintenance efficiency of the staff for the heat exchange tube 3.

[0028] Although the above describes the illustrative specific embodiments of the present application for the convenience of those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all applications and creations using the concept of the present application are within the scope of protection.
