Description

Technical Field

[0001] The invention relates to the field of reactor technology, in particular to a maintenance-free water-cooled reactor and a water-cooling system thereof that is easy to assemble. Background Art

[0002] Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor with current is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid, called an air-core reactor; sometimes, in order to make the solenoid have a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductive reactance (inductor) and capacitive reactance (capacitor) are collectively called reactors. However, since inductors came first in the past and were called reactors, the capacitors people refer to now are capacitive reactances, and reactors specifically refer to inductors.

[0003] The reactor generates a lot of heat during operation. To ensure the normal operation of the reactor and to dissipate heat quickly, water-cooled reactors have emerged, which use water cooling to quickly dissipate heat. However, the installation and connection of the water cooling system of the current water-cooled reactor generally adopts a threaded joint combined with a sealing ring. This method is more troublesome to assemble and requires frequent maintenance. In addition, the sealing ring is prone to aging and leakage, which poses a great safety hazard. Therefore, it is necessary to improve the current water-cooled reactor. Summary of the invention

Each water cooling plate 21 is sandwiched between the corresponding iron core 11 and the corresponding winding 30. Each water cooling plate 21 has a first water inlet 201 and a first water outlet 202.

The water outlet pipe 23 is riveted and connected to a first sleeve pipe 24, and the first sleeve pipe 24 is riveted and connected to the corresponding water inlet pipe 22.

[0042] Specifically, the water-cooling plate 21 is made of aluminum alloy, and includes a main plate 211 and a cover plate 212. The inner side surface of the main plate 211 is concavely provided with a groove (not shown in the figure). The cover plate 212 is stacked on the inner side surface of the main plate 211 and fixed by friction welding. The cover plate 212 covers the groove to form a water flow channel. The aforementioned first water inlet 201 and the first water outlet 202 are respectively connected to the two ends of the water flow channel. In addition, the upper and lower ends of the water-cooling plate 21 are penetrated by the front and rear sides to form a process positioning hole 203.

The ends of the water inlet pipe 22 and the ends of the water outlet pipe 23 are against the corresponding annular step surfaces 242. The middle outer side surface of the first sleeve tube 24 is concavely provided with an annular groove 243, and both ends of the first sleeve tube 24 are extended with annular sleeve sheets 244; in addition, the outer surfaces of both ends of the first sleeve tube 24 are radially expanded to extend annular riveted steps 245, so that the two ends of the first sleeve tube 24 are tightly riveted and fixed to the water inlet pipe 22 and the water outlet pipe 23 respectively, and the leakage prevention effect is more ideal.

[0045] And, the water-cooling plates 21 are in two groups, and the two groups of water-cooling plates 21 are respectively arranged on the front and rear sides of the frame 10, and each group of water-cooling plates 21 is composed of three water-cooling plates 21. In addition, the water-cooling system 20 also includes a manifold 25, which is fixed to the top of the frame 10. The manifold 25 is made of aluminum alloy. The manifold 25 is provided with a water inlet joint 251 and a water outlet joint 252, and the manifold 25 has two second water outlets 253 and two second water inlets 254. Each second water outlet 253 is connected to the water inlet joint 251 and is welded to a second sleeve pipe 26. The two second sleeve pipes 26 are respectively riveted to the water inlet ends of the two groups of water-cooling plates 21, and the outer surfaces of the connecting ends of the second sleeve pipes 26 are radially expanded and extended to have a ring The third sleeve 26 is riveted with a shaped riveted step (not shown in the figure) so that the second sleeve 26 is tightly riveted and fixed to the water inlet end of the water cooling plate 21, and the anti-leakage effect is more ideal; each second water inlet 254 is connected to the water outlet joint 252 and is welded to the third sleeve 27, and the two third sleeves 27 are riveted and connected to the water outlet ends of the two groups of water cooling plates 21, respectively. The outer surface of the connecting end of the third sleeve 27 is radially expanded and extended to have an annular riveted step (not shown in the figure), so that the third sleeve 27 is tightly riveted and fixed to the water outlet end of the water cooling plate 21, and the anti-leakage effect is more ideal. In addition, the specific structure of the third sleeve 27 and the second sleeve 26 is the same as that of the first sleeve 24.

[0046] The assembly process of this embodiment is described in detail as follows:

[0047] First, a water inlet pipe 22 is welded and connected at the first water inlet 201 of each water-cooled plate 21, a water outlet pipe 23 is welded and connected at the first water outlet 202 of each water-cooled plate 21, and a second sleeve pipe 26 is welded and connected at each second water outlet 253 of the manifold 25, and a third sleeve pipe 27 is welded and connected at each second water inlet 254 of the manifold 25; then, the frame 10 is assembled, and each water-cooled plate 21 is fixed on the side of the iron core 11, and the manifold 25 is fixed on the top of the frame 10; then, a coil is wound around the outside of the iron core 11 to form a winding 30; then, the water outlet pipe 23 is riveted and connected to the first sleeve pipe 24, and the first sleeve pipe 24 is riveted and connected to the corresponding water inlet pipe 22, and the two second sleeve pipes 26 are riveted and connected to the water inlet ends of the two groups of water-cooled plates 21, and the two third sleeve pipes 27 are riveted and connected to the water outlet ends of the two groups of water-cooled plates 21.

[0048] When in use, the water inlet joint 251 and the water outlet joint 252 are connected to the external water circuit, and the low-temperature water is input into the manifold 25 from the water inlet joint 251, then flows through each water-cooled plate 21, and then flows back to the manifold 25 and flows out from the water outlet joint 252. During the flow of water, the heat generated by the iron core 11 and the winding 30 is transferred to the water in the water-cooled plate 21, and the heat is taken away by the flowing water, thereby achieving the purpose of lowering the temperature.
