[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a tubular heat exchanger that is easy to maintain, such as Figure 1-5As shown, the easy-to-maintain tubular heat exchanger includes: a tubular heat exchanger body 1, which includes a mounting shell 2 and a connecting shell 3. A mounting plate 201 is disposed inside the mounting shell 2, and a U-shaped tube bundle 202 is fixedly mounted on the mounting plate 201. A connecting plate 301 is fixedly mounted inside the connecting shell 3, and the connecting plate 301 has multiple connecting holes 302, which correspond to the ports of the multiple U-shaped tube bundles 202. A connecting ring 203 is fixedly mounted on the mounting plate 201. A mounting bracket 4 is fixedly mounted on the bottom of the tubular heat exchanger body 1. A placement bracket 5 is disposed on the mounting bracket 4. A first electric telescopic rod 6 is fixedly mounted on the placement bracket 5, and a connecting buckle 7 is fixedly mounted on the output shaft of the first electric telescopic rod 6. The connecting buckle 7 is adapted to the connecting ring 203. A moving mechanism is disposed on the mounting bracket 4 and the placement bracket 5, and the moving mechanism is used to move the U-shaped tube bundle 202.

[0024] In this embodiment, heat exchange between cold and hot fluids can be achieved through the tubular heat exchanger body 1. The working principle of the tubular heat exchanger body 1 is existing technology and will not be elaborated here. When it is necessary to remove the U-shaped tube bundle 202 from the mounting shell 2 for cleaning, the connecting shell 3 and the mounting shell 2 are first disassembled, exposing the connecting ring 203. Then, the moving mechanism is activated by the controller to move the connecting buckle 7 below the connecting ring 203. Then, the first electric telescopic rod 6 is activated by the controller to move the connecting buckle 7 upward. The operator connects the connecting buckle 7 and the connecting ring 203. Then, the moving mechanism is activated again by the controller to pull the U-shaped tube bundle 202 to the outside of the mounting shell 2, removing the U-shaped tube bundle 202 from the mounting shell 2. This facilitates the cleaning of the U-shaped tube bundle 202 by the operator. Throughout the operation, it is convenient to move and disassemble the U-shaped tube bundle 202, thus facilitating the maintenance and cleaning of the U-shaped tube bundle 202 by the operator, providing convenience for the operator.

[0025] In a further preferred embodiment of this utility model, a placement groove 8 is provided on the connecting plate 301, the placement groove 8 is adapted to the connecting ring 203, and the placement groove 8 is used to place the connecting ring 203. Both the mounting shell 2 and the connecting shell 3 are provided with a water inlet and a water outlet. A partition is fixedly installed inside the mounting shell 2, and the water inlet and water outlet on the mounting shell 2 are located above and below the partition, respectively.

[0026] In this embodiment, the connecting ring 203 is conveniently placed through the placement slot 8. When the tubular heat exchanger body 1 is exchanging heat, one fluid (such as hot fluid) enters the U-shaped tube bundle 202 through the inlet on the connecting shell 3 and then exits through the outlet on the connecting shell 3. Another fluid (such as cold fluid) enters the mounting shell 2 through the inlet on the mounting shell 2. Under the action of multiple baffles on the U-shaped tube bundle 202, the fluid is continuously deflected. At the same time, the cold fluid in the mounting shell 2 comes into contact with the U-shaped tube bundle 202. According to the principle of heat exchange, heat is exchanged between the hot and cold fluids. Meanwhile, the fluid in the mounting shell 2 that has undergone heat exchange is discharged through the outlet on the mounting shell 2, thus completing the heat exchange work.

[0027] In a further preferred embodiment of the present invention, the moving mechanism includes: a motor 9 fixedly mounted on the mounting frame 4; a lead screw 10 rotatably mounted on the mounting frame 4, one end of the lead screw 10 being fixedly connected to the output shaft of the motor 9; and a drive block 11 threaded onto the lead screw 10, the drive block 11 being fixedly connected to the placement frame 5.

[0028] In this embodiment, when using the moving mechanism, the controller starts the motor 9 to drive the lead screw 10 to rotate. A limit rod is fixedly installed on the mounting frame 4. The limit rod and the drive block 11 are slidably connected. The limit rod limits the drive block 11, so that the lead screw 10 stably drives the drive block 11 to move, thereby driving the first electric telescopic rod 6 on the placement frame 5 to move. Because the connecting buckle 7 and the connecting ring 203 are connected, the U-shaped tube bundle 202 can be pulled to move to the outside of the mounting shell 2, and the U-shaped tube bundle 202 is moved out of the mounting shell 2, so that the staff can easily clean and maintain the U-shaped tube bundle 202.

[0029] In a further preferred embodiment of this utility model, a support mechanism is provided on the placement rack 5. The support mechanism is used to support the U-shaped tube bundle 202. The support mechanism includes: a second electric telescopic rod 12 fixedly installed on the placement rack 5; and a support plate 13 fixedly installed on the output shaft of the second electric telescopic rod 12. The support plate 13 is used to support the U-shaped tube bundle 202.

[0030] In this embodiment, as the U-shaped tube bundle 202 moves continuously towards the outside of the mounting shell 2, the controller activates the second electric telescopic rod 12 to move the support plate 13 upward, based on the situation where the U-shaped tube bundle 202 moves out of the mounting shell 2. This causes the support plate 13 to contact the bottom of the U-shaped tube bundle 202, thereby providing support for the U-shaped tube bundle 202 and improving the stability of the U-shaped tube bundle 202 during movement.

[0031] In a further preferred embodiment of the present invention, a protective pad is fixedly installed on the top of the support plate 13, and the protective pad is made of rubber.

[0032] In this embodiment, when the support plate 13 moves upward to support the bottom of the U-shaped tube bundle 202, the protective pad comes into contact with the bottom of the U-shaped tube bundle 202, which can protect the bottom of the U-shaped tube bundle 202 and prevent wear on the bottom of the U-shaped tube bundle 202.

[0033] In a further preferred embodiment of the present invention, an auxiliary mechanism is provided at the bottom of the placement rack 5. The auxiliary mechanism includes: a third electric telescopic rod 14 fixedly installed on the placement rack 5; and a placement plate 15 fixedly installed on the output shaft of the third electric telescopic rod 14. An auxiliary wheel 16 is provided on the placement plate 15.

[0034] In this embodiment, before the moving mechanism moves the U-shaped tube bundle 202, the third electric telescopic rod 14 is activated through the operation panel to drive the auxiliary wheel 16 to move down and contact the ground. Thus, when the moving mechanism moves the placement frame 5, the auxiliary wheel 16 can effectively assist the placement frame 5 in moving. On the one hand, it improves the stability of the placement frame 5 when it moves, and on the other hand, it can provide support for the U-shaped tube bundle 202 during its movement.

[0035] In a further preferred embodiment of this utility model, an operation panel is provided on one side of the mounting bracket 4, and the operation panel is used by the staff to perform control operations.

[0036] In this embodiment, the operation panel allows staff to easily move around the entire operation.

[0037] In summary, compared with related technologies, the tubular heat exchanger body 1 allows for heat exchange between cold and hot fluids, and facilitates the movement and disassembly of the U-shaped tube bundle 202, thereby making it easier for staff to maintain and clean the U-shaped tube bundle 202 and providing convenience for staff.
