[0002] Fin-tube heat exchanger is a heat exchange device widely used in the industrial field. It is favored by users for its efficient heat transfer performance and stable operation characteristics. For example, the existing patent with publication number CN216245775U discloses "a fin-tube heat exchanger, including a refrigerant tube, the air inlet side of the refrigerant tube is provided with a heating wire. The refrigerant tube is connected to a refrigerant tube fixing frame, one side of the refrigerant tube fixing frame is connected to a heating wire fixing frame, and the heating wire fixing frame is connected to a heating wire." It can be seen that the application describes a common fin-tube heat exchanger;

When the fin gaps on the fin-tube heat exchanger are blocked, it is impossible to remove it from the inner side of the outer frame for cleaning, resulting in a continuous decrease in the efficiency of the heat exchanger. The cleaning and maintenance of the fin-tube heat exchanger is not convenient in the later stage. Therefore, the utility model proposes a drawer-type fin-tube heat exchanger. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a drawer-type fin-tube heat exchanger, comprising an outer frame 1, in which a plurality of heat exchanger bodies 23 are slidably installed, an end plate 21 is welded and fixed to the front end of the heat exchanger body 23, and the end plate 21 covers the right side surface of the outer frame 1, and two pipe ports 22 are arranged on the surface of the end plate 21, so that when the surface of the heat exchanger body 23 needs to be cleaned later, it is only necessary to pull the heat exchanger body 23 out of the outer frame 1, which is convenient for subsequent maintenance and cleaning;

[0022] A limiting mechanism corresponding to the end plate 21 is provided at the top of the outer frame 1, and the limiting mechanism includes a rectangular seat 31 fixed on the top surface of the outer frame 1, and a movable movable rod 32 is provided at the front end of the rectangular seat 31. A limiting pressure block 33 is welded and fixed to the bottom surface of the movable rod 32, and the bottom end of the limiting pressure block 33 extends to the surface of the end plate 21 and is pressed and contacted with the end plate 21, so that the end plate 21 can be stably pressed and limited to ensure the installation stability of the heat exchanger body 23. An inner slide groove 36 is opened in the rectangular seat 31, and an inner slider 37 and a spring 38 are provided in the inner slide groove 36. The inner end of the movable rod 32 passes through the inner side of the inner slide groove 36 and is rotatably connected to the inner slider 37.

[0023] One end of the spring 38 abuts against the inner wall of the inner slide groove 36 , and the other end of the spring 38 abuts against the side surface of the inner slide block 37 .

[0024] A side hole communicating with the inner slide groove 36 is formed on the right side surface of the rectangular seat 31 , and the side hole corresponds to the movable rod 32 , so that the movable rod 32 can pass through smoothly.

[0025] The clamping block 34 is welded and fixed on the bottom surface of the limiting pressure block 33, and a clamping groove 35 corresponding to the clamping block 34 is opened on the surface of the end plate 21. The clamping block 34 is inserted into the clamping groove 35 to limit the limiting pressure block 33 and ensure that the limiting pressure block 33 stably limits the end plate 21 during daily use. When the heat exchanger body 23 needs to be repaired and cleaned in the future, it is only necessary to pull the movable rod 32 forward so that the inner slider 37 slides to compress the spring 38 and move the clamping block 34 out of the clamping groove 35. At this time, the limiting pressure block 33 and the movable rod 32 can be rotated so that the limiting pressure block 33 no longer blocks and limits the end plate 21, and the limiting mechanism on the end plate 21 is released. At this time, the end plate 21 can be pulled sideways, and the heat exchanger body 23 can be smoothly pulled out of the outer frame 1 for repair and cleaning.

[0026] Among them, a guide wheel structure is provided on the inner side of the outer frame 1, and the guide wheel structure includes a bottom groove 11 and a support pulley 12. The bottom groove 11 is opened at the inner bottom of the outer frame 1, and the support pulley 12 is rotatably installed in the bottom groove 11 through a rotating shaft, and the top end of the support pulley 12 is in rolling contact with the bottom surface of the heat exchanger body 23, which can reduce the resistance when the heat exchanger body 23 is pulled out and pushed in, making it convenient to pull out.

[0027] Example 2

[0028] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the auxiliary positioning structure can be provided to achieve auxiliary positioning of the movable rod 32 after rotation.

[0029] Specifically, the limiting mechanism also includes an auxiliary positioning structure, which is arranged between the movable rod 32 and the rectangular seat 31. The auxiliary positioning structure includes a rubber pad 39, a positioning block 310 and a positioning groove 311. The rubber pad 39 is fixed to the outer surface of the rectangular seat 31, and the bottom surface of the rubber pad 39 is provided with an integrated positioning block 310. Both are made of rubber material and will undergo elastic deformation when squeezed. Two positioning grooves 311 are provided on the surface of the movable rod 32, and the positioning block 310 is squeezed into one of the positioning grooves 311, so that after the movable rod 32 rotates one hundred and eighty degrees, the positioning block 310 will be squeezed into the other positioning groove 311, thereby realizing auxiliary limiting after the movable rod 32 rotates.

[0030] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
