Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, specifically a multifunctional heat exchanger. Background Technology

[0002] A heat exchanger is a highly efficient heat transfer device whose core function is to transfer heat between fluids at different temperatures. It typically consists of a series of pipes or plates that separate two or more fluids while allowing heat to transfer through the pipe walls or plates. In a heat exchanger, the heat released by the high-temperature fluid is absorbed by the low-temperature fluid, thus achieving efficient heat utilization. This equipment is widely used in various industrial fields such as chemical, petroleum, power, and food processing. As a key component such as heaters, coolers, and condensers, it plays a vital role in improving energy efficiency, reducing energy consumption, and minimizing environmental pollution. Heat exchangers are favored by industry due to their compact structure, high efficiency, and broad application prospects.

[0003] For example, patent announcement number CN206177099U discloses a horizontal in-line tube heat exchanger, including a heat exchanger shell, a material inlet at one end of the heat exchanger shell, and a material outlet at the other end. The heat exchanger shell contains several heat exchange tubes arranged side-by-side along the material flow direction. A pair of support baffles are located at both ends of the heat exchange tubes within the heat exchanger shell to support and fix them. A cooling water inlet and a cooling water outlet are distributed on the heat exchanger shell between the two support baffles. Each heat exchange tube contains a helical metal rod. One end of the bolted metal rod has an end baffle with a diameter larger than the outer diameter of the heat exchange tube. The end baffle of the helical metal rod is located at the end of the heat exchange tube at the material inlet. The length of the helical metal rod decreases progressively from the middle of the shell to the edge of the shell. This horizontal in-line tube heat exchanger improves heat exchange efficiency and stabilizes the material outlet temperature.

[0004] In the above technologies, the heat exchange tubes are all fixed inside the shell of the multi-functional heat exchanger. The material is cooled by the flow of cooling water contacting the heat exchange tubes. However, the contact area between the cooling water and the heat exchange tubes is limited, resulting in low heat exchange efficiency. Therefore, the market urgently needs to develop a multi-functional heat exchanger to help people solve the existing problems. Utility Model Content

However, the contact area between the cooling water and the heat exchange tubes is limited, resulting in low heat exchange efficiency.

One end of the liquid material inlet pipe extends into the inside of the transmission box, and one end of the conveying pipe passes through the middle of the first pulley and is connected to one end of the liquid material inlet pipe through a second rotary joint.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, by designing a semi-circular flow divider, a semi-circular flow collector and multiple heat exchange tubes arranged in an array between them, and enabling these components to rotate synchronously, the contact area between the heat exchange tubes and the cooling water is effectively increased, thereby significantly improving the heat exchange efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a multifunctional heat exchanger, comprising a multifunctional heat exchanger housing 1. A semi-circular flow divider 2 is rotatably disposed on one side inside the multifunctional heat exchanger housing 1, and a circular flow divider plate 201 is fixedly connected to one side of the semi-circular flow divider 2. A semi-circular flow collector 3 is rotatably disposed on the other side inside the multifunctional heat exchanger housing 1, and a circular flow collector plate 301 is fixedly connected to one side of the semi-circular flow collector 3. Multiple heat exchange tubes 4 are arranged in an array and fixedly connected between the circular flow divider plate 201 and the semi-circular flow collector 3. A liquid material discharge pipe 103 is fixedly connected to the middle of one end face of the multifunctional heat exchanger housing 1. One end of the liquid material discharge pipe 103 extends into the interior of the multifunctional heat exchanger housing 1 and is connected to the middle of the side of the semi-circular flow collector 3 away from the circular flow collector plate 301 through a first rotary joint 302, so that the semi-circular flow collector 3 can pass through the first rotary joint 302. The multi-functional heat exchanger housing 1 is rotated. A limiting tube 104 is fixedly connected to the middle of the other end face. A transmission box 5 is fixedly installed on one end face of the multi-functional heat exchanger housing 1 and outside the limiting tube 104. A conveying pipe 202 is fixedly connected to the middle of the side of the semi-circular diverter 2 away from the circular diverter plate 201. The conveying pipe 202 extends through the middle of the limiting tube 104 into the transmission box 5 and is fixedly connected to the first pulley 203. A rotating sealing ring 105 is provided between the outer wall of the conveying pipe 202 and the inner wall of the limiting tube 104. The rotating sealing ring 105 seals the conveying pipe 202 and the limiting tube 104, and at the same time allows the semi-circular diverter 2 and the conveying pipe 202 to rotate. When the semi-circular diverter 2 and the semi-circular collector 3 rotate synchronously, they drive multiple heat exchange tubes 4 to rotate, so that the multiple heat exchange tubes 4 increase the contact area with the flowing cooling water when they rotate, thereby improving the heat exchange efficiency.

[0024] Please see Figure 2 and Figure 4A liquid material inlet pipe 501 is fixedly connected to the lower middle part of one side end face of the transmission box 5. One end of the liquid material inlet pipe 501 extends into the interior of the transmission box 5. One end of the conveying pipe 202 passes through the middle of the first pulley 203 and is connected to one end of the liquid material inlet pipe 501 through the second rotary joint 502. The liquid material that needs to be heated is sent into the semi-circular diverter 2 through the liquid material inlet pipe 501 and then diverted to multiple heat exchange tubes 4. After flowing through the heat exchange tubes 4, it enters the semi-circular collector 3 and collects, and finally exits from the liquid material outlet pipe 103. Inside the transmission box 5, a drive motor 6 is fixedly installed at the upper end. The output shaft of the drive motor 6 is connected to a transmission shaft 601 through a coupling. A second pulley 602 is fixedly connected to the transmission shaft 601. The second pulley 602 is connected to the first pulley 203 through a belt 603. The drive motor 6 drives the transmission shaft 601 to rotate, which in turn drives the conveying pipe 202 to rotate through the belt 603. This causes the conveying pipe 202 to drive the semi-circular flow divider 2 to rotate, thus achieving synchronous rotation of the semi-circular flow divider 2, multiple heat exchange tubes 4, and the semi-circular flow collector 3.

[0025] Please see Figure 1 and Figure 2 A cooling water inlet pipe 101 is fixedly connected to one side of the upper end of the multi-functional heat exchanger housing 1. A cooling water outlet pipe 102 is fixedly connected to the lower end of the side face of the multi-functional heat exchanger housing 1 away from the cooling water inlet pipe 101. Cooling water is injected into the interior of the multi-functional heat exchanger housing 1 through the cooling water inlet pipe 101. After the cooling water flows inside the multi-functional heat exchanger housing 1 and exchanges heat with the heat exchange tube 4, it is discharged from the cooling water outlet pipe 102.

[0026] Working Principle: In operation, the liquid material to be heat-exchanged first flows into the semi-circular distribution hood 2 through the liquid material inlet pipe 501 and then through the conveying pipe 202, and is then distributed to multiple heat exchange tubes 4 by the circular distribution plate 201. Simultaneously, the drive motor 6 starts, driving the transmission shaft 601 to rotate, which in turn drives the first pulley 203 and its connected conveying pipe 202, semi-circular distribution hood 2, multiple heat exchange tubes 4, and semi-circular collector hood 3 to rotate synchronously via the belt 603. This rotational design effectively increases the contact area between the heat exchange tubes 4 and the cooling water flowing inside the multi-functional heat exchanger shell 1, thereby significantly improving heat exchange efficiency. The cooling water is injected into the multi-functional heat exchanger shell 1 through the cooling water inlet pipe 101, flows within the shell, and fully contacts the rotating heat exchange tubes 4 for heat exchange, before being discharged from the cooling water outlet pipe 102. After heat exchange, the liquid material gathers inside the semi-circular manifold 3 and is connected to the liquid material discharge pipe 103 through the first rotary joint 302, and finally flows out from the liquid material discharge pipe 103, completing the entire heat exchange process.
