In fig. 1 to 4, the number of the water cooling modules 12 is only an example, and in a practical application scenario, the number of the water cooling modules 12 may be very large, the number of the first connecting pipes 23 and the second connecting pipes 24 may also be very large, the connection positions required to be reserved on the water inlet pipe 21 and the water outlet pipe 22 may also be very large, and since the cooling water needs to reach each water cooling module 12, the water pressure and the water amount required by the cooling water may also be very large.

In the prior art, the cooling water is generally tap water, and because tap water has high hardness and contains a lot of calcium and magnesium ions, calcium carbonate which is insoluble in water and magnesium hydroxide which is insoluble in water are formed after high temperature treatment, and the precipitates are attached to the pipe wall. During the blockage removal process, the blockage is mainly found at the outlet positions of the first connecting pipe 23 and the second connecting pipe 24, and the inventor finds that the blockage is caused by the installation and connection structure of each connecting pipe. In the prior art, as shown in fig. 7, taking a connection structure at an outlet of the second connection pipe 24 'as an example, the outlet pipe is generally provided with a connection seat 26' for connecting the second connection pipe 24 ', the second connection pipe 24' is sleeved on the periphery of the connection seat 26 'and fastened by a clip, in the connection structure, a stacking portion 264' exists between the second connection pipe 24 'and the connection seat 26', when water flows downwards from the second connection pipe 24 'into the connection seat 26', sediment is stacked on the stacking portion 264 ', and the inner diameter of the connection seat 26' is very small, so that blockage is easily caused. At the inlet position of the second connection pipe 24 ', since water flows from the connection seat 26 ' to the second connection pipe 24 ', the accumulation and the blockage are not easily caused at the inlet position using this connection structure. Similarly, the first connecting pipe in the prior art generally adopts the connecting structure.

The present embodiment reduces the occurrence of clogging phenomenon from both the aspect of changing the water quality and the aspect of changing the structure of the connection socket 26. As shown in fig. 8, the cooling water of the water circulation in this embodiment is purified water, further, the cooling system of this embodiment further includes a cooling tower 3, an ionization cylinder 4 and a water pump 5, the cooling tower 3, the ionization cylinder 4, the water pump 5 and the cooling module 2 form water circulation, wherein an ion exchange resin and a filter screen are arranged in the ionization cylinder 4, calcium and magnesium ions in water are replaced by sodium ions, and the generated sodium salt has high solubility and is not easy to form precipitates, and then other particulate impurities in water, such as verdigris and the like, can be filtered through the filter screen.

Further, as shown in fig. 3 and fig. 9 to 10, in this embodiment, a connection seat is not provided on the water inlet pipe 21, but a through hole is provided on the water inlet pipe 21, then the first end of the first flow sensor 251 is directly welded at the through hole to form communication, the second end of the first flow sensor 251 is connected with the first end of the first connection pipe 23 through the existing connection structure, that is, the connection structure in fig. 7 (the first end of the first connection pipe 23 is sleeved on the second end of the first flow sensor 251), and a connection seat 26 is provided at the water inlet end of the water cooling device to be connected with the second end of the first connection pipe 23; further, the water outlet end of the water cooling device is connected to the first end of the second connection pipe 24 through the existing connection structure, the connection seat 26 is disposed at the first end of the second flow sensor 252 to be connected to the second end of the second connection pipe 24, and the second end of the second flow sensor 252 is welded to the water outlet pipe 22 and forms a communication. Referring to fig. 9 to 10, taking the connection structure of the connection holder 26 and the second connection tube 24 of the second flow sensor 252 as an example, the insertion end of the connection holder 26 is provided with an annular notch 261, the inner diameter of the second connection tube 24 is set to be the same as the minimum inner diameter of the connection holder 26, and after the second connection tube 24 is inserted into the annular notch 261, the inner wall of the second connection tube 24 is flush with the inner wall of the connection holder 26, so that there is no accumulation part in the prior art, and there is no situation that sediment is accumulated at this place to cause blockage. Similarly, the connecting seat 26 and the first connecting pipe 23 which are arranged on the water inlet end of the water cooling device are also of the structure, the inner diameter of the connecting seat 26 of the water inlet end of the water cooling device is the same as that of the first connecting pipe 23, so that the accumulation part does not exist at the outlet of the first connecting pipe 23 and the outlet of the second connecting pipe 24, namely the second end, and precipitates are not easy to accumulate in the water circulation process, so that the blocking probability is reduced.

Like this, this embodiment on the one hand through improving quality of water, reduces the sediment and the impurity that produce the jam from the source, and on the other hand sets up the connecting seat on water-cooling device's the end of intaking and second flow sensor makes even there is the sediment also difficult the emergence to block up in the aquatic.

According to the cooling system for the control cabinet of the intermediate frequency furnace, the occurrence of blocking is reduced, and even if blocking occurs, the blocking position can be accurately found in time, so that manual blocking clearing is performed, and the cooling system is strong in pertinence and high in efficiency.

Example two:

the difference between the present embodiment and the first embodiment is that each water cooling module 12 in the present embodiment includes a plurality of water cooling devices, and the plurality of water cooling devices are connected in series through an intermediate connection pipe (not shown in the figure). Specifically, the water inlet end of the first water-cooling device is connected to the water inlet pipe 21 through the first connecting pipe 23 and the first flow sensor 251, the water outlet end of the first water-cooling device is connected to the water inlet end of the second water-cooling device, the water outlet end of the second water-cooling device is connected to the water inlet end of the third water-cooling device, and so on, the water outlet end of the last water-cooling device is connected to the water outlet pipe 22 through the second connecting pipe 24 and the second flow sensor 252. Due to the fact that the blocking probability is reduced through the measures in the first embodiment, a plurality of water cooling devices can be used as a group, the number of pipelines and flow sensors is reduced, and certain cost can be saved.

Example three:

the embodiment is optimized on the basis of the first embodiment, intelligent automatic blockage clearing can be achieved, specifically, electronic flowmeters are adopted by the first flow sensor and the second flow sensor in the embodiment, each electronic flowmeter is connected to the main control module, the main control module numbers each electronic flowmeter, and the blockage position is judged according to feedback information of each electronic flowmeter.

Further, as shown in fig. 11, the cooling assembly 2 of this embodiment further includes a plurality of tee pipes 28, a first port of each tee pipe 28 is welded to the water outlet pipe 22, a second port of each tee pipe 28 is connected to a second flow sensor 252, a vibrator 281 is connected to a third port of each tee pipe 28, the vibrator 281 is selected from, but not limited to, ultrasonic vibrators 281, and it is of course possible to dispose the tee pipe 28 between the second flow sensor 252 and the second connecting pipe 24, and dispose the connecting base 26 on the tee pipe 28 to connect with the second connecting pipe 24. Furthermore, a three-way pipe is also arranged between the water inlet end of each water cooling device and the corresponding first connecting pipe 23, the first port of the three-way pipe is connected to the water inlet end of the water cooling device, the second port of the three-way pipe is connected to the first connecting pipe 23, and the third port of the three-way pipe is provided with a vibrator.

Although the portion of piling up has been got rid of through the structure of above-mentioned connecting seat 26, but still very little relatively because the pipe diameter of second connecting pipe 24 and first connecting pipe 23, still probably take place to block up, so, this embodiment sets up three-way pipe 28, when detecting that the flow sensor rotational speed on a certain return circuit slows down promptly will block up, ultrasonic vibrator 281 vibration through on the three-way pipe 28 makes adnexed precipitate drop, then wash away along with the circulating water, thereby realize automatic clear stifled, make the condition of jam further reduce, and do not need artifical clear stifled, intelligent degree is high, only need regularly to wash whole pipeline.

Water leakage may occur at the connection due to the vibration of the vibrator 281, and an accident may be easily caused when water leakage occurs. As shown in fig. 9 to 10, taking the connection structure of the connection socket 26 and the second connection pipe 24 at the second flow sensor 252 as an example, the present embodiment provides three mounting grooves on the connection socket 26, two of which are provided on the inner wall of the annular notch 261 of the connection socket 26, in which the first sealing ring 262 is fitted, and the other of which is provided on the end of the connection socket 26, in which the second sealing ring 263 is fitted. A pressing portion 241 is provided on the second connection pipe 24 near the edge, and after the second connection pipe 24 is inserted into the connection seat 26, the outer wall of the second connection pipe 24 presses the two first sealing rings 262 to form a radial seal, and the pressing portion 241 presses the second sealing ring 263 to form an axial seal. Further, in the present embodiment, an external thread is provided on an outer wall of the connecting socket 26, and the connecting socket 26 is fixed by the nut 27, which is fitted, and the nut 27 presses the pressing portion 241 to press the second sealing ring 263. Because the axial and radial upward sealing is formed and the multi-stage sealing is adopted, the sealing effect is greatly improved, and the hidden danger of water leakage is avoided.

Further, as shown in fig. 12, in this embodiment, a temperature sensor 29 is disposed between each second connecting pipe 24 and the water outlet pipe 22, and the temperature of the water outlet end of each second connecting pipe 24 is detected, so that if it is detected that the temperature of a certain temperature sensor 29 exceeds the standard, and the first connecting pipe 23 and the second connecting pipe 24 on the branch connected thereto are not blocked, that is, the flow meter operates normally, it can be determined that the water cooling device has a fault, and an alarm is prompted and the time delay is stopped.

Therefore, the cooling system for the control cabinet of the intermediate frequency furnace can automatically clear the blockage when the blockage occurs or before the blockage occurs.
