The embodiment of the application provides a temperature control method, device and system of a laser.
For easy understanding, a temperature control system of the laser is described first, and a method and a device for controlling the temperature of the laser are described in detail on the basis of the system.
Referring to fig. 1, fig. 1 is a schematic block diagram of a temperature control system of a laser according to an embodiment of the present application. The system comprises a laser 11, a water cooler 12 and a controller 13. The temperature monitoring unit is used for monitoring the temperature of the laser in real time; the laser is arranged on a water cooling plate of the water cooling machine. The controller receives detection data of the temperature monitoring unit and the temperature sensor in real time so as to control water flow of the water cooler, and the water cooler realizes liquid cooling of the laser through flowing cooling liquid.
After the temperature control system of the laser provided by the embodiment of the application is started, the controller executes the temperature control method of the laser provided by the embodiment to control the water flow of the water cooler, so that the temperature of the laser is controlled. Specifically, referring to fig. 2, fig. 2 is a schematic block diagram of a method for controlling a temperature of a laser according to an embodiment of the present application.
As shown in FIG. 2, the temperature control method of the laser includes steps S110 to S140.
S110, acquiring the current output power of a laser and the current water flow of a water cooler for carrying out liquid cooling on the laser;
s120, if the current output power of the laser is not matched with the current water flow of the water cooler, adjusting the water flow of the water cooler to be a first water flow;
s130, adjusting the water flow of the water cooler according to a first curve of the temperature of the laser along with the change of output power based on the first water flow so as to control the temperature of the laser;
and S140, if the current output power of the laser is matched with the current water flow of the water cooler, adjusting the water flow of the water cooler according to the first curve based on the current water flow of the water cooler so as to control the temperature of the laser.
Specifically, when the water cooling machine is used for cooling the laser, the laser is usually cooled in a full-load working state, that is, the laser is cooled by using the water cooling machine to adopt the maximum water flow. However, the laser may be in a full load state, i.e. operating at maximum output power, or in a non-full load state, i.e. operating at output power lower than the maximum output power of the laser during operation. At this time, the laser in the full-load state is cooled by the water cooler by adopting the maximum water flow, so that the waste of the water cooler resources is not necessarily caused, but the laser in the non-full-load state is cooled, and the laser is not necessarily cooled in the full-load working state.
Therefore, the current output power of the laser and the current water flow of the water cooler for carrying out liquid cooling on the laser are obtained, whether the current output power of the laser is matched with the current water flow of the water cooler or not is further determined, if so, the water flow of the water cooler can be regulated according to a first curve of the temperature of the laser changing along with the output power, and the temperature of the laser is further controlled; if the water flows are not matched, the current water flow of the water cooler is required to be adjusted to be the first water flow matched with the current output power of the laser, then the temperature of the laser is adjusted to be the temperature matched with the current output power on the basis of the first water flow, finally, the water flow of the water cooler can be adjusted by adopting a first curve of the temperature of the laser changing along with the output power, and then the temperature of the laser is controlled, so that the technical problem that the water cooler is wasted due to the fact that the water cooler cannot adaptively adjust the water flow of the water cooler in the prior art is solved, the situation that the water cooler is always in a full-load working state is avoided, the resource waste of the water cooler is reduced, and the liquid cooling cost of the laser is reduced.
In this embodiment, the first water flow is a water flow that can quickly adjust the current temperature of the laser to be matched with the current output power of the laser, and the first water flow can be the current water flow of the water cooling machine or the flow after the water flow adjustment of the water cooling machine. The first curve is a curve of the temperature of the laser as a function of output power. The laser is typically operated at a steady output power when in an operating state. However, when the output power of the laser in the working state is required to be adjusted, the temperature of the laser also changes along with the adjusted output power, so that after the current water flow of the water cooler is adjusted to be the water flow matched with the current output power of the laser, the temperature curve, namely the first curve, in the subsequent output power change process of the laser is required to be determined in advance, and then the water flow of the water cooler is adaptively adjusted according to the temperature curve in the subsequent output power change process of the laser, so that the temperature of the laser can be controlled.
In other embodiments of the application, as shown in fig. 3, steps S210 and S220 are further included before step S110.
S210, acquiring a second curve of the water flow of the water cooler along with the change of the output power of the laser;
s220, determining whether the current output power of the laser is matched with the current water flow of the water cooler according to the second curve.
In this embodiment, the second curve is a curve of the water flow rate of the water cooler along with the output power of the laser, that is, one output power of the laser corresponds to one water flow rate, and the water flow rate can control the temperature of the laser within a stable range, and the laser within the range can output stable wavelength. After the current output power of the laser and the current water flow of the water cooler for cooling the laser are obtained, comparing the current output power of the laser with the current water flow of the water cooler through a second curve, and further determining whether the current output power of the laser is matched with the current water flow of the water cooler or not.
In other embodiments of the application, as shown in fig. 4, steps S310 and S320 are further included before step S210.
S310, acquiring a first curve of the temperature of the laser along with the change of output power and a third curve of the water cooling temperature of the water cooling machine along with the change of water flow;
s320, constructing a second curve of the water flow of the water cooler along with the output power change of the laser according to the first curve and the third curve.
The device that generates heat in the laser instrument is equipped with temperature monitoring unit, and it realizes monitoring the temperature of laser instrument through the temperature of the device that generates heat in the detection laser instrument, is equipped with temperature sensor in the water-cooling machine, and it is used for detecting the water-cooling temperature in the water-cooling machine. The first curve is a curve of the temperature of a heating device in the laser along with the change of the output power of the laser, and the third curve is a curve of the water cooling temperature of the water cooling machine along with the change of the water flow.
In this embodiment, an output power of the laser corresponds to a temperature, and when the water cooling machine cools the laser with a water flow rate matching the output power, the water flow rate also corresponds to a temperature, and the two temperatures are not substantially equal, which has a temperature difference, that is, when there is a temperature difference between the laser and the water cooling machine, the laser can output a stable wavelength at an output power.
The temperature difference can be determined from the temperatures of the water cooling machine and the laser in the full-load working state. After the temperature difference is determined, a first curve of the temperature of the laser along with the change of the output power can be obtained, the curve of the temperature of the corresponding water cooler along with the change of the output power of the laser can be determined through the temperature difference and the first curve, then a third curve of the water cooling temperature of the water cooler along with the change of the water flow can be obtained according to the curve and the water flow of the water cooler in a full-load working state, and finally a second curve of the water flow of the water cooler along with the change of the output power of the laser can be constructed through the first curve and the second curve.
In other inventive embodiments, as shown in fig. 5, step S220 includes steps S221, S222, and S223.
S221, determining a second water flow of the water cooler from the second curve according to the current output power;
s222, acquiring a flow difference between the current water flow of the water cooler and the second water flow;
s223, determining whether the current output power of the laser is matched with the current water flow of the water cooler according to the flow difference.
In this embodiment, the current output power of the laser is used to determine the water flow of the laser which needs to be subjected to liquid cooling, namely, the second water flow, from the second curve, then the second water flow is compared with the current water flow of the water cooler, so as to determine whether the flow difference between the second water flow and the current water flow of the water cooler is within a preset threshold value, and if the flow difference is within the preset threshold value, then the current output power of the laser can be determined to be matched with the current water flow of the water cooler; if the flow difference is not within the preset threshold, the fact that the current output power of the laser is not matched with the current flow of the water cooler can be determined.
In other inventive embodiments, as shown in fig. 6, step S120 includes steps S121 and S122.
S121, acquiring the current temperature of the laser and the current water cooling temperature of the water cooling machine;
s122, adjusting the water flow of the water cooler to be a first water flow according to the current temperature of the laser and the current water cooling temperature of the water cooler.
In this embodiment, the current temperature of the laser may or may not match the current output power of the laser. After the current temperature of the laser is obtained, whether the current temperature of the laser is matched with the current output power or not is determined through a first curve of the temperature of the laser changing along with the output power, and whether the water flow of the water cooling machine needs to be increased or decreased is further determined. Meanwhile, the current water cooling temperature of the water cooling machine can be matched with the current water flow of the water cooling machine, and the current water cooling temperature of the water cooling machine can be not matched. Therefore, after the current temperature of the laser is obtained, whether the current temperature of the water cooler is matched with the current water flow or not is determined through a third curve of the water cooling temperature of the water cooler along with the change of the water flow, so that the flow difference of the water cooler, which is required to be subjected to flow adjustment, is determined, and the water flow of the water cooler can be adjusted to be the water flow which can be matched with the current output power of the laser.
In other inventive embodiments, as shown in fig. 7, step S122 includes steps S1221 and S1222.
S1221, determining whether the current temperature of the laser is matched with the current water cooling temperature of the water cooling machine;
s1222, if the current temperature of the laser is matched with the current water cooling temperature of the water cooling machine, adjusting the water flow of the water cooling machine to be a first water flow.
In this embodiment, when determining whether the current temperature of the laser is matched with the current water cooling temperature of the water cooling machine, specifically, determining whether the temperature difference between the current temperature of the laser and the current water cooling temperature of the water cooling machine is within a preset temperature difference range, if the temperature difference is not within the preset temperature difference range, determining that the current temperature of the laser is not matched with the current water cooling temperature of the water cooling machine, that is, the temperature of the laser is usually too high, the current water flow cannot control the temperature of the laser within a range, and then, the water flow of the water cooling machine needs to be rapidly increased to rapidly cool the laser; if the temperature difference is in the range of the preset temperature difference, the current temperature of the laser is determined to be matched with the current water cooling temperature of the water cooling machine, at the moment, the temperature of the laser is only slightly too high, the current water flow can control the temperature of the laser in a range, and at the moment, the temperature of the laser can be quickly reduced by only adjusting the water flow of the water cooling machine to be the first water flow.
In other embodiments of the application, as shown in fig. 8, steps S1223 and S1224 are further included after step S1221.
S1223, if the current temperature of the laser is not matched with the current water cooling temperature of the water cooling machine, adjusting the water flow of the water cooling machine to be a third water flow;
s1224, after the temperature of the laser is matched with the water cooling temperature of the water cooler, adjusting the water flow of the water cooler from the third water flow to the first water flow.
In this embodiment, the temperature difference between the current temperature of the laser and the current water cooling temperature of the water cooling machine is not in the range of the preset temperature difference, the current water flow cannot control the temperature of the laser in a range, at this time, the water flow of the water cooling machine needs to be rapidly increased to rapidly cool the laser, that is, only the current water flow of the water cooling machine is adjusted to be the first water flow, so that the laser cannot be rapidly cooled, the water flow of the water cooling machine needs to be continuously increased until the water flow of the water cooling machine is greater than the first water flow, that is, after the third water flow is greater than the first water flow, the rapid cooling of the laser can be realized. Meanwhile, after the laser is rapidly cooled through the third water flow, when the temperature of the laser is matched with the water cooling temperature of the water cooler, in order to reduce the waste of water cooler resources, the water flow of the water cooler can be adjusted from the third water flow to the first water flow, and then the water flow of the water cooler can be adjusted according to the first curve, so that the temperature of the laser is controlled.
According to the temperature control method of the laser, after the current output power of the laser and the current water flow of the water cooler for carrying out liquid cooling on the laser are obtained, whether the current output power of the laser is matched with the current water flow of the water cooler or not is judged, if not, the water flow of the water cooler is adjusted to be the first water flow matched with the current output power of the laser, and then the water flow of the water cooler is adjusted through a first curve of the temperature change of the laser along with the output power, so that the temperature of the laser is controlled; if the water flows are matched, the water flow of the water cooling machine is adjusted through the first curve on the basis of the current water flow, so that the temperature of the laser is controlled, the water cooling machine is prevented from being in a full-load working state all the time, the resource waste of the water cooling machine is reduced, and the liquid cooling cost of the laser is reduced.
