[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 - Figure 3 As shown in [drawings], an embodiment provided by the present utility model: A heat exchanger that is convenient for maintenance includes a shell 1. The bottom of the shell 1 is slidably connected with a mounting seat 2. Mounting components are provided on both the front and rear sides of the mounting seat 2. The mounting component includes a push rod 4. The push rod 4 is slidably connected inside the mounting seat 2. One end of the push rod 4 is fixedly connected with a horizontal plate 7. Two connecting blocks 8 are fixedly connected to the end of the horizontal plate 7 away from the push rod 4. Rotating rods 9 are rotatably connected inside both of the two connecting blocks 8. One end of each of the two rotating rods 9 away from the two connecting blocks 8 is rotatably connected with a transmission block 10. Clamping blocks 11 are fixedly connected to the ends of the two transmission blocks 10 away from the two rotating rods 9 respectively. A first limiting plate 6 is fixedly connected to the middle of the push rod 4. A first compression spring 5 is fixedly connected to one side of the first limiting plate 6. Two card slots 13 are opened on both the left and right sides of the bottom of the shell 1. Two slide rods 12 are fixedly connected to the middle of the push rod 4. Connecting pipes 14 are fixedly connected to both the upper and lower sides of the front side of the shell 1. Connecting components are provided at the ends of the two connecting pipes 14 away from the shell 1. The outer parts of the two clamping blocks 11 are respectively slidably connected inside the card slots 13. The inner parts of the two clamping blocks 11 are respectively slidably connected to the outer circumference of the slide rods 12. A push plate 3 is fixedly connected to the end of the push rod 4 away from the connecting block 8.

[0024] Specifically, the housing 1 is the main body of the heat exchanger, which is a prior art. The mounting base 2 is used to facilitate the installation of the housing 1. The push plate 3 is used to control the movement of the push rod 4. The cross plate 7 is used to drive the connecting block 8 to move. The first limiting plate 6 is used to squeeze the first compression spring 5. The first compression spring 5 is used to provide the thrust for the reset movement. The rotating rod 9 is used to connect the connecting block 8 and the transmission block 10. When the connecting block 8 moves, it will drive the rotating rod 9 to move together, thereby causing the rotating rod 9 to rotate. The clamping block 11 is used to cooperate with the clamping groove 13, so that when the clamping block 11 is located in the clamping groove 13, it limits the housing 1. The sliding rod 12 is used to support the sliding of the clamping block 11. The first connecting pipe 14 and the second connecting pipe 17 are connected and assembled for use, so that the heat exchange water enters the heat exchanger. The assembly plate 15 and the mounting plate 16 are used to connect the first connecting pipe 14 and the second connecting pipe 17.

[0025] Referring to Figure 1 , Figure 2 , Figure 4 , the connecting component includes an assembly plate 15. The assembly plate 15 is fixedly connected to the outer periphery of the first connecting pipe 14. One end of the assembly plate 15 away from the first connecting pipe 14 is slidably connected with a mounting plate 16. The middle of the mounting plate 16 is fixedly connected with a second connecting pipe 17. Two mounting rods 24 are fixedly connected to one end of the mounting plate 16 close to the assembly plate 15. Two disassembly components are arranged inside the assembly plate 15. The disassembly component includes an insertion rod 19. The insertion rod 19 is slidably connected inside the assembly plate 15. A second limiting plate 21 is fixedly connected to the middle of the insertion rod 19. A second compression spring 20 is fixedly connected to the top of the second limiting plate 21. A slot 23 is opened inside the mounting rod 24. The insertion rod 19 is slidably connected inside the slot 23. A limiting groove 22 is opened inside the first connecting pipe 14. The second limiting plate 21 is slidably connected inside the limiting groove 22. One end of the insertion rod 19 away from the second limiting plate 21 is rotatably connected with a pull ring 18.

[0026] Specifically, the mounting rod 24 is used to insert into the assembly plate 15, so that the first connecting pipe 14 and the mounting plate 16 can be connected. The insertion rod 19 is used to insert into the slot 23 opened in the mounting rod 24, so as to limit the mounting rod 24. The pull ring 18 is used to facilitate the pulling of the insertion rod 19 to move. The second limiting plate 21 is used to squeeze the second compression spring 20. The second compression spring 20 is used to provide an elastic thrust to push the second limiting plate 21 to move. The slot 23 is used to cooperate with the mounting rod 24. When the insertion rod 19 is inside the slot 23, the first connecting pipe 14 and the assembly plate 15 are connected together. When the insertion rod 19 slides out of the slot 23, the first connecting pipe 14 and the assembly plate 15 can be separated. The limiting groove 22 is used to accommodate the sliding of the second limiting plate 21.

[0027] Working principle: When installing the housing 1 and the mounting base 2, first pull the two push plates 3 away from each other. When the two push plates 3 move away from each other, the two push rods 4 also drive the cross plate 7 to move, and the first limiting plate 6 will compress the first compression spring 5. When the cross plate 7 moves, the two connecting blocks 8 move accordingly. When the connecting blocks 8 move, the rotating rods 9 will rotate, causing the two transmission blocks 10 to drive the clamping blocks 11 to move towards each other along the sliding rod 12. Then, insert the housing 1 into the interior of the mounting base 2. After the housing 1 is inserted into the mounting base 2, the push plates 3 can be released. The first compression spring 5 will reset and generate a thrust to push the first limiting plate 6 to move when it loses the extrusion of the first limiting plate 6. Then, when the cross plate 7 resets accordingly, the two rotating rods 9 will push the two transmission blocks 10 to drive the clamping blocks 11 to move away from each other along the sliding rod 12, so that the two clamping blocks 11 are embedded into the interior of the clamping slots 13, thereby limiting the housing 1 and assembling the housing 1 and the mounting base 2.

[0028] Secondly, when assembling the first connecting pipe 14 and the second connecting pipe 17, pull the two pull rings 18. The two insertion rods 19 move together with the pulling of the pull rings 18. When the insertion rods 19 move, the second limiting plate 21 moves together with the insertion rods 19 and compresses the second compression spring 20. Then, insert the two mounting rods 24 into the interior of the first connecting pipe 14. After ensuring that the insertion rods 19 can be inserted into the insertion slots 23, the pull rings 18 can be released. The second compression spring 20 will reset and generate a thrust to push the second limiting plate 21 to move when it loses the pressure of the second limiting plate 21, so that the insertion rods 19 are inserted into the insertion slots 23, and thus the assembling plate 15 and the mounting plate 16 can be connected, and the first connecting pipe 14 and the second connecting pipe 17 are assembled.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
