In order to overcome the defect that the cost is high because the manufacturing process of the mica sheet involves a complicated procedure of silver baking, a certain amount of copper foils and mica paper can be adopted, the copper foils and the mica paper are alternately laminated to form a layered structure, one mica paper is arranged between two adjacent copper foils, the layered structure can be used as a capacitor core 100, the mica paper does not need to be silver baked, and the cost is greatly reduced.

The cover 300 is made of a material with good thermal conductivity, such as copper, copper alloy or aluminum alloy.
A water inlet 310 through which water is supplied into the water-cooled space and a water outlet 320 through which water is discharged from the water-cooled space are provided on the capping plate 300; the heat of the resonant capacitor is taken away through water circulation, and the effect of water cooling is achieved.

The water inlet buffering structure can be an arc-shaped groove 330 arranged on the cover plate 300, when water enters the water cooling space, the water is firstly blocked and buffered by the arc-shaped groove wall of the arc-shaped groove 330, water flow is guided to the end part of the arc-shaped groove 330, the water flow impacts the groove wall at the end part of the arc-shaped groove 330 and then returns, and in the impact process of the water flow back and forth, the cooling water and the cover plate 300 are subjected to heat transfer fully, and the heat of the resonant capacitor is taken away through the water flow.
The arcuate recess 330 may be provided in the first cover plate 210, but is preferably provided in the cover plate 300, avoiding excessive adjustment of the structure of the resonant capacitor itself to increase the cost.

When water enters from the first end 331 of the arc-shaped groove 330 and flows along the arc-shaped groove 330 to the second end 332, the water flow is slower as the second end 332 approaches the second end 332 due to the depth of the second end 332 is larger than that of the first end 331, and the flow of the water returning from the second end 332 is facilitated.
In the process of extending from the first end 331 to the second end 332 of the arc-shaped groove 330, smooth transition can be achieved, or a plurality of steps are arranged at the bottom of the groove for transition, and the arrangement of the steps increases the buffering of cooling water, thereby being beneficial to improving the heat dissipation effect.

The water drainage buffer structure enables cooling water to be discharged after being buffered again in the water cooling space, so that the cooling water can sufficiently participate in heat absorption of the resonant capacitor, and the water cooling heat dissipation efficiency of the resonant capacitor is improved.
In particular embodiments, the drainage buffer structure includes, but is not limited to, the following structures.
The drainage buffer structure is an annular groove 340, and the annular groove 340 is disposed on the cover plate 300. The water in the water cooling space is guided by the annular groove 340 to flow around the annular groove 340, which not only increases the contact area between the water and the capping plate 300, but also effectively buffers the cooling water by forming a circular flow by the arrangement of the annular groove 340, so that the cooling water and the capping plate 300 can be more sufficiently heat-transferred to take away the heat of the resonant capacitor through the water flow.
The annular recess 340 may be formed in the first cap plate 210, but is preferably formed in the cap plate 300, thereby avoiding the need to adjust the structure of the resonant capacitor itself to increase the cost.
The annular groove 340 includes a first side 341 and a second side 342, the first side 341 is in communication with the drain port 320, the second side 342 is away from the drain port 320, the annular groove 340 may have the same depth, and preferably, the depth of the second side 342 of the annular groove 340 is greater than the depth of the first side 341. When water enters from the first side 341 of the annular groove 340 and flows along the annular groove 340 toward the second side 342, since the depth of the second side 342 is greater than that of the first side, the water flow is more gradual as the water flow approaches the second side 342, and the water returning from the second side 342 flows out from the water outlet 320 of the first side 341 more easily.
The arc-shaped groove 330 is communicated with the annular groove 340 through a peripheral groove 350, the depth of the peripheral groove 350 is less than that of the arc-shaped groove 330, and the depth of the peripheral groove 350 is less than that of the annular groove 340. The provision of the peripheral groove 350 allows more contact between the water and the first cover plate 210, and more loop and circulation of the water in the cooling space, so that the cooling water is more buffered and is more fully heat-transferred to the first cover plate 210, and the heat of the resonant capacitor is taken away.
For example, after entering from the water inlet 310, the water reaches the first end 331 of the arc-shaped groove 330, and flows toward the second end 332 under the guidance of the arc-shaped groove 330, and meanwhile, part of the water flows into the upper peripheral groove 351; the water is buffered by the influence of the arc groove 330, is buffered again after the second end 332 of the arc groove 330 returns, and then enters the upper peripheral groove 351; the water flows into the first side 341 of the annular groove from the upper peripheral groove 351, one part of the water is discharged from the water discharge port 320, the other part of the water is guided by the annular groove to form a circular flow, and the circular flow is subjected to sufficient heat transfer with the cover plate 300 and is discharged from the water discharge port 320 when returning to the first side 341 through the circular flow; the water flowing out of the upper circumferential groove 351 and returning from the ring groove may partially enter the lower circumferential groove 352 to flow toward the first end 331 of the arc groove 330, forming a large loop, so that the water can be sufficiently heat-exchanged with the capping plate 300, thereby improving the water-cooling heat dissipation efficiency of the resonant capacitor.
Still be equipped with first seal groove 360 on closing cap plate 300, first seal groove 360 is equipped with the sealing washer around the water-cooling space arrangement in the first seal groove 360 for the water-cooling space is the confined space. A second sealing groove is formed in the first cover plate 210, the second sealing groove corresponds to the first sealing groove 360, and the sealing ring is located between the first sealing groove 360 and the second sealing groove. The sealing groove is used for preventing the sealing ring from deviating and ensuring the sealing effect of the water cooling space. When the cover plate 300 covers the first cover plate 210, the water cooling space forms a closed space due to the sealing ring and the sealing groove, thereby preventing cooling water from leaking and ensuring the stability of the heat dissipation effect.
The sealing cover plate 300 is detachably connected with the first cover plate 210, for example, by a stud nut. A plurality of fixing holes 380 are formed in corresponding positions of the cover plate 300 and the first cover plate 210, the fixing holes 380 are through holes or screw holes, for example, a plurality of through holes are uniformly arranged around the peripheries of the cover plate 300 and the first cover plate 210, the cover plate 300 is fixed on the first cover plate 210 through stud nuts, and stress is uniform in all directions, so that the tightness of the water cooling space is stably ensured.
A through hole 400 is formed in the center of the resonant capacitor, and the through hole 400 sequentially penetrates through the second cover 220, the capacitor core 100, the cover plate 300, and the first cover 210 at intermediate positions thereof, thereby facilitating the extraction of the electrodes and the mounting and fixing. In order to prevent the water-cooling space from leaking water due to the influence of the through-hole 400, the cover plate 300 is provided with a double-layer flange in which the through-hole 400 passes through the middle of the inner flange 372, a third seal groove 370 is formed between the inner flange 372 and the outer flange 371, and a seal ring is also provided in the third seal groove 370. An annular receiving groove and an annular protrusion are provided at corresponding positions on the first cover plate 210, and the through hole 400 passes through the middle of the annular protrusion. When the cover plate 300 covers the first cover plate 210, the outer flange 371 of the cover plate 300 is inserted into the annular receiving groove of the first cover plate 210, and the annular protrusion of the first cover plate 210 abuts against the sealing ring in the third sealing groove 370, so that the through hole 400 does not affect the normal operation of the water cooling space. Preferably, a sealing gasket is arranged at the bottom of the annular receiving groove of the first cover plate 210, and the outer layer flange 371 abuts against the sealing gasket at the bottom of the receiving groove, so as to further ensure the sealing effect of the water cooling space.
A plurality of mounting holes 221 are uniformly arranged at the periphery of the second capping plate 300, and the mounting holes 221 are in the form of counterbores to facilitate mounting and fixing the resonance capacitor at a desired position.
