[0002] A supercomputer is a super-large electronic computer with strong computing and data processing capabilities. Its main features are high speed and large capacity, and it is equipped with a variety of external and peripheral devices and a rich and high-function software system. When a supercomputer is running, it will generate a large amount of heat. If this heat is not taken away in time, it will damage the supercomputer, affecting its performance and service life. Therefore, it is necessary to cool the supercomputer.

[0003] As one of the options for the supercomputer cooling system, in the liquid cooling system of a supercomputer, a solenoid valve is often used to adjust the direction, flow rate, speed, and other parameters of the refrigerant.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer toFigure 1-16In an embodiment of the present invention, a micro solenoid valve for a supercomputer cooling system that can be quickly disassembled and assembled includes a micro solenoid valve 100 and a one-way valve 200. The micro solenoid valve 100 is inserted into the one-way valve 200 as a whole and fixedly connected to form a combination. The micro solenoid valve 100 includes a valve body 8, a connecting seat 9, a solenoid valve spring 10, a shell 11, a coil 12, a U-shaped iron 13, a solenoid valve inlet sealing O-ring 16, a solenoid valve outlet sealing O-ring 19, a diaphragm 21, a connecting head 22, a cover plate 23, a moving iron core 24 and a fixed iron core 25. The valve body 8 is fixedly arranged on the connecting seat 9. The valve body 8 includes a valve body base 81. The valve body base The top of the seat 81 is provided with a valve body inner shaft 82 and a valve body outer shaft 83 in an annular distribution upward, the bottom of the valve body base (81) is provided with a protrusion (84) downward, and the bottom of the protrusion (84) is provided with a waist-shaped channel (841) extending upward, and the solenoid valve inlet sealing O-ring 16 is provided on the upper part of the outer side of the valve body inner shaft 82, so that when the micro solenoid valve 100 is inserted into the one-way valve 200 as a whole, the connection between the valve body 8 and the one-way valve 200 is tighter, and when in use, the refrigerant is effectively prevented from leaking out from the connection between the valve body 8 and the one-way valve 200; the solenoid valve outlet sealing O-ring 19 is provided in the middle of the outer side of the valve body outer shaft 83, so that the connection between the valve body 8 and the base 400 is tighter. The connection is tighter, and when in use, it effectively prevents the refrigerant from leaking out from the connection between the valve body 8 and the base 400; the connecting seat 9 is set to a hollow annular step structure, and the hollow annular step structure is used to fix the diaphragm 21, the connecting head 22, the solenoid valve spring 10 and the moving iron core 24. The diaphragm 21 is set between the valve body 8 and the connecting seat 9. When the micro solenoid valve 100 is in the closed state, the diaphragm 21 is in the original state.

When the micro solenoid valve 100 is in the open state, the diaphragm 21 moves downward, closing the waist-shaped channel 841.

The spring 10 is arranged at the bottom inner of the connecting seat 9 and is sleeved on the upper surface of the moving iron core 24. When the micro solenoid valve is energized, the moving iron core 24 moves downward due to the magnetic attraction, driving the spring 10 to compress downward and causing the spring 10 to undergo elastic deformation. When the micro solenoid valve is de-energized, the moving iron core 24 loses its magnetic attraction, and the spring 10 returns to its natural state, thereby driving the iron core 24 to move upward, restoring the moving iron core 24 to its original state.The stationary iron core 25 is fixedly arranged on the upper side of the bottom of the U-shaped iron 13 through swaging connection. The cover plate 23 and the top of the U-shaped iron 13 are riveted and pressed to form a cavity. A core fixing bushing 50 is arranged in the middle of the cavity. The stationary iron core 25 and the moving iron core 24 are arranged up and down in the core fixing bushing 50. A gap is arranged between the upper side of the stationary iron core 25 and the lower side of the moving iron core 24. The coil 12 is sleeved outside the core fixing bushing 50.

The valve body 8 is fixedly connected to the connecting seat 9 through the second fixing hole 813 and the first screw 85. The diameter of the through hole 812 is larger than the maximum outer diameter of the valve seat bottom plate fixing screw 713. When the micro solenoid valve 100 needs to be disassembled, it is not necessary to disassemble the valve seat bottom plate fixing screw 713, which is very convenient.

[0042] Preferably, for the above-mentioned micro solenoid valve that can be quickly disassembled and assembled in the supercomputer cooling system, a second circular liquid inlet port 821 is provided in the middle of the top of the inner shaft 82 of the valve body, and a circular liquid outlet port 831 is provided on the upper part of the outer side of the outer shaft 83 of the valve body.

[0046] Working principle:

[0047] Please refer to Figure 14 , insert the micro solenoid valve 100 into the check valve 200. When it is in the energized state, the overall micro solenoid valve is in the open state. The refrigerant enters from the base liquid inlet a, then passes through the first circular liquid inlet 41 into the inner shaft 4, reaches the top of the diaphragm 21 through the second circular liquid inlet 821, then flows to the circular liquid outlet 831, and then flows through the waist-shaped liquid outlet 33 to the base liquid outlet b.
