Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] With reference to Figures 1-11 A high-temperature liquid combined cycle cooling system comprises a water pump assembly 1, a siphon assembly 2 and a return pipe 3. The water pump assembly 1 is installed on a horizontal ground and is used for pumping high-temperature liquid to the highest position reached by the lift. The pipeline of the siphon assembly 2 passes through a condenser 4 installed on the roof of a workshop. The siphon assembly 2 can deliver the liquid pumped by the water pump assembly 1 to the condenser 4 for cooling. The return pipe 3 delivers part of the cooled liquid back to the water pump assembly 1 to reduce the temperature of the liquid delivered by the water pump assembly 1.

[0034] The water pump assembly 1 comprises an inlet pipe 11, a pump 12 and a water storage pool 13. The water storage pool 13 is installed at the maximum lift position of the pump 12. High-temperature liquid enters the pump 12 from the inlet pipe 11 and is pumped into the water storage pool 13 for storage.

[0035] The siphon assembly 2 comprises a siphon pipe 21 and a distribution chamber 22. The siphon pipe 21 is in an inverted U shape. The two ends of the siphon pipe 21 are respectively connected to the water storage pool 13 and the distribution chamber 22. The siphon pipe 21 passes through the condenser 4 installed on the roof of the workshop. The liquid sucked by the siphon pipe 21 from the water storage pool 13 is cooled by the condenser 4 when passing through the condenser 4. The water storage pool 13 and the distribution chamber 22 are both connected to the outside atmosphere. The height of the distribution chamber 22 is lower than that of the water storage pool 13. When the water storage pool 13, the siphon pipe 21 and the distribution chamber 22 are all filled with liquid, a siphon effect is generated. The liquid in the water storage pool 13 is continuously delivered to the distribution chamber 22 through the siphon pipe 21.

[0036] The internal space of the distribution chamber 22 is divided into a liquid collecting cavity 2201 and a return cavity 2202. The end of the siphon pipe 21 is inserted into the liquid collecting cavity 2201. The liquid cooled by the condenser 4 will first fill the liquid collecting cavity 2201. After the liquid collecting cavity 2201 is filled, the liquid will overflow into the return cavity 2202. Part of the liquid in the return cavity 2202 is drawn away by the return pipe 3. Another part of the liquid in the return cavity 2202 is recycled and reused by a recycling pipe 5 connected to the return cavity 2202.

[0037] The end of the siphon 21 extending into the water reservoir 13 is also provided with a control water valve 14, which is electrically connected with the pump 12, and the control water valve 14 is opened when the pump 12 is started to pump liquid, and the siphon 21 continuously pumps the liquid in the water reservoir 13; after the pump 12 is stopped to pump liquid, the control water valve 14 is also closed, and the siphon 21 is sealed by the control water valve 14 at one end and by the liquid in the liquid collecting cavity 2201 at the other end, and the siphon 21 is filled with liquid which no longer flows. The siphon 21 always maintains a vacuum, and when the pump 12 is started again to make the liquid level submerge the end of the siphon 21, the siphon 21 can immediately produce a siphon effect.

[0040] A temperature probe 155 is installed at the center of the flow converging cone cylinder 152, the temperature probe 155 is electrically connected with a PLC controller 156 installed in the honeycomb cylinder 151, and the temperature probe 155 can monitor the temperature of the mixed liquid in the flow converging cone cylinder 152 in real time and transmit the temperature data to the PLC controller 156.

The length of the swing rod 1542 can be changed, because the swing radius of the swing motor 1541 driving the swing rod 1542 is smaller than the radius of the circle where the guide groove 1504 is located, the swing rod 1542 with variable length can make the electromagnetic block 1543 move along the guide groove 1504 smoothly.

[0046] The blocking block 1531 is installed with a permanent magnet block 1533 near one side of the honeycomb cylinder 151, and the corresponding belt moving assembly 154 electromagnetic block 1543 is energized to magnetically attract and fix the blocking assembly 153; if the blocking assembly 153 is to be moved, the swing motor 1541 drives the blocking block 1531 attracted by the electromagnetic block 1543 to move from one end to the other end of the guide groove 1504, and each blocking block 1531 attracted by the electromagnetic block 1543 will also be moved synchronously, after the blocking block 1531 is moved once, a part of the electromagnetic block 1543 is de-energized and re-arranged to the initial position, a part of the electromagnetic block 1543 is continuously energized to keep the position of the blocking block 1531, after the de-energized electromagnetic block 1543 is re-arranged to the initial position, it is re-energized to keep the position of the blocking block 1531, the originally energized electromagnetic block 1543 is de-energized and re-arranged to the initial position and re-energized, and then the electromagnetic block 1543 is swung to drive the blocking assembly 153 to continue to move. Through the above method, the position of the blocking assembly 153 in the vortex groove 1502 can be adjusted by the belt moving assembly 154.

[0047] The temperature probe 155 transmits the temperature data of the liquid in the confluence cone cylinder 152 to the PLC controller 156, and the PLC controller 156 controls the operation of each electromagnetic block 1543 and swing motor 1541 according to the data to move the blocking assembly 153 to the appropriate position, and the blocking assembly 153 blocks different numbers of liquid channels 1501 communicated with the return pipe 3 or the liquid inlet pipe 11 by moving to different positions in the vortex groove 1502, so as to adjust the flow of high-temperature liquid and low-temperature liquid into the confluence cone cylinder 152, and then adjust the mixed liquid in the confluence cone cylinder 152 to the appropriate temperature.
