[0018] Compared with the prior art, the beneficial effects of this utility model are: the multi-recirculation condenser:

[0019] 1. In this device, three heat exchange tubes are arranged in an equilateral triangle along the axis of the outer shell. The fluid to be cooled flows inside the heat exchange tubes and comes into contact with the cooling medium for cooling.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a multi-recirculation condenser, including a shell 1, a left side plate 2, a right side plate 3, a left end cap 4, a right end cap 5, a connecting flange 6, a first pipe 7, a second pipe 8, a third pipe 9, a fourth pipe 10, a heat exchange tube 11, an upper baffle plate 12, a lower baffle plate 13, a connecting rod 14, and a spacer tube 15.

[0031] The outer casing 1 is a pipe structure that runs through both ends. A left side plate 2 is fixedly installed at one end of the outer casing 1, and a right side plate 3 is fixedly installed at the other end. The outer surface of the left side plate 2 has annular threaded connection holes. A left end cap 4 is provided on the side surface of the left side plate 2. The left end cap 4 is an open, hollow structure. A connecting flange 6 is fixed to the outer surface of the left end cap 4, and the left end cap 4 is bolted to the threaded connection holes on the surface of the left side plate 2 through the connecting flange 6. A right end cap 5 is provided on the side surface of the right side plate 3. The right end cap 5 is an open, hollow structure. A connecting flange 6 is fixed to the outer surface of the right end cap 5, and the right end cap 5 is bolted to the threaded connection holes on the surface of the right side plate 3 through the connecting flange 6. The left side plate 2 and the right side plate 3 form a chamber structure between the left end cap 4, the right end cap 5, and the outer casing 1. The chamber formed by the left side plate 2 and the left end cap 4 is marked as the left chamber, and the chamber formed by the right side plate 3 and the right end cap 5 is marked as the right chamber. The left side plate 2, the right side plate 3, and the outer casing 1 constitute... The chamber is marked as the middle chamber. A first pipe 7 is installed through the surface of the left end cap 4 and inserted into the left chamber. A second pipe 8 is installed on one side of the first pipe 7 and is installed through the surface of the right end cap 5 and inserted into the right chamber. A third pipe 9 is installed on one side of the second pipe 8 and is installed through the lower surface of the outer shell 1 and inserted into the middle chamber. A fourth pipe 10 is installed through the upper surface of the outer shell 1 and inserted into the middle chamber. The third pipe 9 is located on the surface of the outer shell 1 near the left end cap 4, and the fourth pipe 10 is located on the surface of the outer shell 1 near the right end cap 5. A heat exchange tube 11 is installed inside the outer shell 1. The heat exchange tube 11 has a through-end structure. The two ends of the heat exchange tube 11 are installed through the surfaces of the left side plate 2 and the right side plate 3 and inserted into the left and right chambers, respectively. There are 3 heat exchange tubes 11, which are arranged in an equilateral triangle at the axis of the outer shell 1.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the fluid to be cooled is input from pipe 7 (number 1), and the cooling medium is input from pipe 9 (number 3). The cooling medium enters the middle chamber from pipe 9 and flows along the middle chamber to pipe 10 (number 4) and out. The fluid to be cooled enters the left chamber from pipe 7 (number 1), enters the heat exchange tube 11 in the left chamber, flows along the heat exchange tube 11 and enters the right chamber from the other end, and is output from pipe 8 (number 2). As the fluid to be cooled flows along the heat exchange tube 11, it comes into full contact with the cooling medium through the tube wall of the heat exchange tube 11, thereby cooling the fluid. The cooled fluid flows out from pipe 10 (number 4).

[0033] The interior of the outer casing 1 is equipped with a turbulence structure. This turbulence structure increases the residence time of the cooling medium within the outer casing 1 via an upper turbulence plate 12 and a lower turbulence plate 13. The turbulence structure includes an upper turbulence plate 12, which is fan-shaped and has circular mounting holes on its outer surface. Lower turbulence plates 13 are spaced apart on one side of the upper turbulence plate 12, and each lower turbulence plate 13 is fan-shaped, reversing the direction of the upper turbulence plate 12. Multiple upper turbulence plates 12 and lower turbulence plates 13 are staggered and equidistantly distributed inside the outer casing 1. The lower spoiler 13 is fixedly connected to the same set of connecting rods 14. The connecting rods 14 pass through the mounting holes fixed on the surfaces of the upper spoiler 12 and the lower spoiler 13. The two ends of the connecting rods 14 are fixedly connected to the surfaces of the left side plate 2 and the right side plate 3, respectively. Multiple upper spoilers 12 are fixedly connected to spacer tubes 15. The two ends of the spacer tubes 15 are fixedly installed on the surfaces of the left side plate 2 and the right side plate 3, respectively. Multiple lower spoilers 13 are fixedly connected to another spacer tube 15. The two ends of the spacer tube 15 are fixedly installed on the surfaces of the left side plate 2 and the right side plate 3, respectively.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, the cooling medium enters the middle chamber from pipe 9 and flows along the middle chamber, eventually exiting from pipe 10. During the flow of the cooling medium, it is blocked and guided by the upper baffle 12 and the lower baffle 13. Therefore, the flow path of the cooling medium in the middle chamber is curved, thereby increasing the residence time of the cooling medium in the outer shell 1, allowing for more thorough heat exchange with the heat exchange tube 11, and improving the heat exchange efficiency of the condenser.

[0035] Working principle: When using this multi-recirculation condenser, the fluid to be cooled is input from pipe 7 and then flows into heat exchange tube 11. The cooling medium enters the middle chamber from pipe 9. After heat exchange is completed, the hot medium flows into the right chamber through heat exchange tube 11 and then flows out from pipe 8. The cooling medium flows out from pipe 10. The upper baffle 12 and lower baffle 13 inside the outer shell 1 increase the residence time of the cooling medium, further improving the cooling performance of the device, ensuring that the fluid can be fully cooled, and increasing the overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
