Description

Technical Field

[0001] This application relates to the technical field of heat exchangers, and in particular to a two-phase flow phase change reactor heat exchanger. Background Technology

[0002] Reactors are commonly used electrical devices in power systems. They are a type of inductor and mainly utilize the inductive reactance characteristics of coils to regulate the current, voltage, and power in a circuit. They are widely used in power systems and industrial fields.

[0003] A reactor consists of a housing, inside which is installed an iron core and a coil. The iron core is made of laminated silicon steel sheets, and the coil is tightly wound around the outer wall of the iron core. When current flows through the coil of the reactor, the change in current generates a changing magnetic field in the coil, which in turn induces a reverse electromotive force (EMF) at the ends of the coil. This reverse EMF opposes the natural change in current, thereby controlling the circuit.

[0004] When a reactor operates in a power system, the coil generates heat as current flows through it. This is especially true during high-current or high-frequency operation, when the coil is prone to overheating. The accumulation of a large amount of heat in the coil can seriously affect the performance and lifespan of the equipment. Summary of the Invention

[0005] In order to dissipate heat from the coil of the reactor, this application provides a two-phase flow-phase changeover reactor heat exchanger, which has the effect of dissipating heat from the coil of the reactor separately.

[0006] The two-phase flow phase change reactor heat exchanger provided in this application adopts the following technical solution: A two-phase flow-phase variable reactor heat exchanger includes a liquid-cooled plate disposed inside a coil. A heat dissipation chamber is formed inside the liquid-cooled plate. An outlet pipe is connected to the top of the liquid-cooled plate, and an inlet pipe is connected to the bottom of the liquid-cooled plate. Both the outlet pipe and the inlet pipe are connected to the heat dissipation chamber. A radiator is disposed on the housing above the coil and the liquid-cooled plate. One end of the radiator is connected to the outlet pipe, and the other end is connected to the inlet pipe.

[0007] By adopting the above technical solution, the heat dissipation chamber within the liquid-cooled plate can convert the cold medium into a hot medium, and the radiator can convert the hot medium into a cold medium, thus realizing the heat transfer of the coil. When the reactor is working, the cold medium in the inlet pipe is introduced into the heat dissipation chamber to absorb heat from the coil, causing the coil temperature to drop. Then, the cold medium evaporates into a hot medium and flows into the radiator through the outlet pipe. After cooling, the hot medium becomes a cold medium. This cycle repeats, and the coordinated work of the radiator and the liquid-cooled plate regulates the heat balance, meaning that this application can provide individual heat dissipation for the reactor coil.

[0008] Optionally, a manifold is provided at the end of the exhaust pipe away from the liquid cooling plate, and a first metal flexible tube is provided at the end of the manifold away from the exhaust pipe. Both the exhaust pipe and the first metal flexible tube are connected to the manifold, and the end of the first metal flexible tube away from the manifold is connected to the radiator.

[0009] By adopting the above technical solution, the manifold can connect multiple vent pipes, which facilitates the installation and removal of the vent pipes.

[0010] Optionally, a liquid collection box is provided at the end of the liquid inlet pipe away from the liquid cooling plate, and a second metal flexible tube is provided at the end of the liquid collection box away from the liquid inlet pipe. Both the liquid inlet pipe and the second metal flexible tube are connected to the liquid collection box, and the end of the second metal flexible tube away from the liquid collection box is connected to the radiator.

[0011] By adopting the above technical solution, the liquid collection box can be connected to multiple liquid inlet pipes, which facilitates the installation and disassembly of the liquid inlet pipes.

[0012] Optionally, the liquid cooling plate is configured as multiple pieces, with the vent pipes at the top of each liquid cooling plate connected to a manifold box, and the liquid inlet pipes at the bottom of each liquid cooling plate connected to a liquid collection box. Connection configuration. By adopting the above technical solution and setting multiple liquid cooling plates, the heat exchange efficiency of the coil can be increased, further improving the heat dissipation effect of the reactor.

[0013] Optionally, the liquid cooling plate is provided with an interface at both the top and bottom, and the two interfaces are arranged diagonally. The interface at the top of the liquid cooling plate is connected to the air outlet pipe, and the interface at the bottom of the liquid cooling plate is connected to the liquid inlet pipe.

[0014] By adopting the above technical solution, the cold medium enters the liquid cooling plate through the interface at the bottom of the liquid cooling plate, carries away the heat from the inner wall of the liquid cooling plate, evaporates to form the heat medium, and then flows out through the interface at the top of the liquid cooling plate. The diagonal arrangement of the two interfaces extends the flow path of the medium. After the cold medium absorbs heat and evaporates to form the heat medium, it needs to pass through the entire heat dissipation chamber, further improving the heat dissipation effect of the coil.

[0015] Optionally, the radiator includes an air inlet box, an outlet box, and multiple heat dissipation plates, with the multiple heat dissipation plates located between the air inlet box and the outlet box; each heat dissipation plate has a cavity, and each heat dissipation plate is connected to the air inlet box and the outlet box respectively. The end of the air inlet box away from the heat dissipation plate is connected to an air outlet pipe, and the end of the outlet box away from the heat dissipation plate is connected to an inlet pipe. Multiple heat dissipation fins are fixedly arranged between the air inlet box and the outlet box, and the heat dissipation fins are spaced apart from the heat dissipation plates.

[0016] By adopting the above technical solution, the multiple heat dissipation plates inside the radiator increase the heat exchange area. Combined with the use of heat sinks, the heat medium is transformed into a cold medium, which also improves the heat exchange effect of the heat medium.

[0017] Optionally, a fan is mounted on the housing, the fan being located between the heat sink and the housing, with the fan vent facing the heat sink.

[0018] By adopting the above technical solution, when the heat transfer medium is introduced into the radiator along the air outlet pipe, the fan blows air and accelerates the airflow, which can reduce the temperature of the radiator, allowing the heat transfer medium to quickly become a cold transfer medium and enhance the heat dissipation effect of the radiator.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. When the reactor starts working, the cold medium is introduced into the heat dissipation chamber through the liquid inlet pipe to absorb the heat generated by the coil and evaporate to form the hot medium, which lowers the coil temperature. Then it is introduced into the radiator through the gas outlet pipe for cooling, forming the cold medium. This cycle is repeated multiple times, which can dissipate heat from the reactor coil individually. 2. When the heat transfer medium is introduced into the radiator through the air outlet pipe, the fan blows the air in the radiator, which can effectively reduce the temperature inside the radiator and enhance the heat dissipation effect of the radiator. 3. The manifold can connect to multiple vent pipes, and the liquid collection box can connect to multiple liquid inlet pipes, facilitating the installation and removal of the vent pipes and liquid inlet pipes.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a two-phase flow-phase variable reactor heat exchanger, referring to... Figure 1-3The reactor core includes a liquid-cooled plate 1 and a radiator 7. The liquid-cooled plate 1 is wound and clamped by a coil 2 on the reactor core. One end of the liquid-cooled plate 1 is connected to an exhaust pipe 4, and the other end of the liquid-cooled plate 1 away from the exhaust pipe 4 is connected to an inlet pipe 5. A heat dissipation chamber 3 is formed inside the liquid-cooled plate 1, and both the exhaust pipe 4 and the inlet pipe 5 are connected to the heat dissipation chamber 3. The radiator 7 is located above the coil 2 and the liquid-cooled plate 1. One end of the radiator 7 is connected to the end of the exhaust pipe 4 away from the liquid-cooled plate 1, and the other end of the radiator 7 is connected to the end of the inlet pipe 5 away from the liquid-cooled plate 1.

[0024] During reactor operation, the heat generated by coil 2 is transferred to liquid cooling plate 1. The cooling medium in inlet pipe 5 enters heat dissipation chamber 3, carrying away the heat from liquid cooling plate 1. The cooling medium evaporates to form a heating medium, which lowers the temperature of coil 2. The heating medium flows through outlet pipe 4 into radiator 7. After releasing heat through radiator 7, it liquefies to form a cooling medium, which then flows back to liquid cooling plate 1 through inlet pipe 5. This cycle repeats multiple times, providing individual cooling for reactor coil 2.

[0025] To further improve the heat dissipation efficiency of the reactor, the number, size, and layout of the liquid cooling plates 1, as well as the size parameters of the heat dissipation chamber 3, can be adaptively adjusted according to the reactor type. By arranging a certain number of liquid cooling plates 1, the heat exchange efficiency of the coil 2 can be increased, thereby improving the heat dissipation effect on the reactor. Correspondingly, the number of liquid cooling plates 1, the exhaust pipe 4, and the liquid inlet pipe 5 are matched to ensure that each liquid cooling plate 1 is connected to both the exhaust pipe 4 and the liquid inlet pipe 5.

[0026] Reference Figure 2 and Figure 3 The liquid cooling plate 1 has interfaces 12 fixed at both its top and bottom ends. These interfaces 12 are arranged diagonally. The interface 12 at the top of the liquid cooling plate 1 connects to the exhaust pipe 4, and the interface 12 at the bottom of the liquid cooling plate 1 connects to the liquid inlet pipe 5. Both interfaces 12, the exhaust pipe 4, and the liquid inlet pipe 5 are all connected to the heat dissipation chamber 3. The diagonal arrangement of the interfaces 12 at the top and bottom of the liquid cooling plate 1 extends the flow path of the medium, facilitating the full flow of both the cold and hot media inside the liquid cooling plate 1, carrying away heat from the inner wall of the liquid cooling plate 1, and improving the heat dissipation efficiency of the coil 2.

[0027] Reference Figure 2 To facilitate the installation and removal of the exhaust pipe 4, a manifold box 8 is threadedly connected to the end of the exhaust pipe 4 away from the liquid cooling plate 1, and the exhaust pipe 4 is connected to the manifold box 8. A first metal flexible hose 9 is threadedly connected to the end of the manifold box 8 away from the exhaust pipe 4, and the end of the first metal flexible hose 9 away from the manifold box 8 is threadedly connected to the radiator 7. When there are multiple liquid cooling plates 1, multiple exhaust pipes 4 are connected to the manifold box 8, and the manifold box 8 can connect the liquid cooling plate 1 and the radiator 7, which facilitates the installation and removal of the exhaust pipe 4.

[0028] Reference Figure 2 To facilitate the installation and removal of the liquid inlet pipe 5, a liquid collection box 10 is threadedly connected to the end of the liquid inlet pipe 5 away from the liquid cooling plate 1, and the liquid inlet pipe 5 and the liquid collection box 10 are connected in a continuous manner. A second metal flexible tube 11 is threadedly connected to the end of the liquid collection box 10 away from the liquid inlet pipe 5, and the end of the second metal flexible tube 11 away from the liquid collection box 10 is threadedly connected to the radiator 7. When there are multiple liquid cooling plates 1, multiple liquid inlet pipes 5 are connected to the manifold box 8, and the liquid collection box 10 can connect the liquid cooling plate 1 and the radiator 7, which facilitates the installation and removal of the liquid inlet pipe 5.

[0029] Reference Figure 3 Both the vent pipe 4 and the inlet pipe 5 are equipped with sealing joints 17. The other end of the sealing joint 17, away from the vent pipe 4 or the inlet pipe 5, is inserted into the manifold box 8, the liquid collection box 10, or the liquid cooling plate 1. This can reduce leakage at the connection and improve the sealing performance at the connection between the vent pipe 4 and the manifold box 8 or the liquid cooling plate 1, as well as the sealing performance at the connection between the inlet pipe 5 and the liquid collection box 10 or the liquid cooling plate 1.

[0030] Reference Figure 1 and Figure 4 The housing 6 has two support rods 16, and the radiator 7 is fixedly mounted on the two support rods 16. To improve the heat dissipation effect of the radiator 7, the radiator 7 includes an air inlet box 701, an outlet box 702, and multiple heat dissipation plates 703. The air inlet box 701 and the outlet box 702 are fixed to the support rods 16 respectively. One end of the heat dissipation plate 703 is fixedly mounted on the air inlet box 701, and the other end of the heat dissipation plate 703 away from the air inlet box 701 is fixedly mounted on the outlet box 702. A cavity 13 is formed inside the heat dissipation plate 703, and the cavity 13 communicates with the air inlet box 701 and the outlet box 702. The end of the air inlet box 701 away from the heat dissipation plate 703 is connected to the first metal hose 9, and the end of the outlet box 702 away from the heat dissipation plate 703 is connected to the second metal hose 11. Multiple heat dissipation fins 14 are fixedly mounted between the air inlet box 701 and the outlet box 702, and the heat dissipation fins 14 are spaced apart from the heat dissipation plate 703. When the heat transfer medium is introduced into the heat sink 703, the heat sink 14 helps to dissipate heat and cool the heat transfer medium, which is beneficial to improving the heat dissipation effect of the heat sink 7.

[0031] Reference Figure 1 and Figure 4 A fan 15 is mounted on the housing 6, located below the heat sink 7, with the fan 15's air vent facing the heat sink 7. When the heat transfer medium passes through the air intake box 701 into the heat sink 703, the fan 15 blows air, which can carry away the heat from the heat sink 14 and the outer wall of the heat sink 703, thus cooling the heat transfer medium inside the heat sink 703 and helping to improve the heat dissipation effect of the heat sink 7.

[0032] The implementation principle of a two-phase flow phase-change reactor heat exchanger disclosed in this application is as follows: When the reactor is working, the heat generated by the temperature rise of the coil 2 is transferred to the liquid cooling plate 1, and a high-temperature environment is formed in the heat dissipation chamber 3; when the cold medium is introduced into the inlet pipe 5 along the liquid collection box 10, the cold medium enters the heat dissipation chamber 3 under its own gravity, taking away the heat of the liquid cooling plate 1, and at the same time evaporates to form a hot medium, which reduces the temperature of the coil 2; under the action of buoyancy, the hot medium enters the manifold box 8 along the outlet pipe 4, and then enters the radiator 7 along the first metal hose 9. Under the cooling action of the heat sink 14 and the fan 15, the hot medium is converted into a cold medium, and then enters the liquid collection box 10 along the second metal hose 11; the cold medium circulates repeatedly, and the synergistic effect of the radiator 7 and the liquid cooling plate 1 regulates the heat conversion of the coil 2, realizing the individual heat dissipation of the coil 2 of the reactor.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
