The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a heat dissipation system of a high-power gap laser according to an embodiment of the present disclosure.
Referring to fig. 1, the heat dissipation system of the high-power gap laser is provided with a first circulating water pump 1, a speed-regulating water pump 2, a second circulating water pump 3 and a heat dissipation water pump 4. The heat-radiating water pump 4 is a large water pump that works in match with a high-power gap laser. The first circulating water pump 1, the speed-regulating water pump 2 and the second circulating water pump 3 are all matched working circulating water pumps, wherein the speed-regulating water pump 2 is a water pump with controllable flow.
Referring to fig. 1, the heat dissipation system of the high-power gap laser is provided with a first water tank 5, a second water tank 6 and a third water tank 7, wherein the volume of the third water tank 7 is larger than the volume of the first water tank 5 and/or the second water tank 6. In some embodiments, the first tank 5 has a volume a, the second tank 6 has a volume a, and the third tank 7 has a volume B. The bottom of the first water tank 5 is connected with one end of a water pipe, and the other end of the water pipe is connected with the top of the second water tank 6. The bottom of the second water tank 6 is connected with one end of a water pipe, and the other end of the water pipe is connected with the top of the third water tank 7. The bottoms of the first water tank 5 and the second water tank 6 are respectively connected with a first electromagnetic valve 8 and a second electromagnetic valve 9 for controlling the on-off of the water path. The first electromagnetic valve 8 and the second electromagnetic valve 9 are respectively connected with the speed-regulating water pump 2 and then connected with the third water tank 7. When the first electromagnetic valve 8 or the second electromagnetic valve 9 is opened, circulating water can be pumped into the third water tank 7 through the speed-regulating water pump 2. The circulating water in the third water tank 7 can be pumped back into the first water tank 5 by the second circulating water pump 3 connected with the bottom of the third water tank 7.
Referring to fig. 1, in some embodiments, a first circulating water pump 1 and a refrigeration unit 10 are disposed between the top of the first water tank 5 and the top of the second water tank 6, the first circulating water pump 1 pumps circulating water in the first water tank 5 into the refrigeration unit 10 for refrigeration, and the refrigerated circulating water enters the second water tank 6. The refrigeration unit 10 is realized by a micro direct current compressor, so that the purpose of miniaturization of the refrigeration system is achieved. The refrigeration unit 10 mainly cools the circulating water in the first water tank 5 and the second water tank 6, and stores the cold quantity in advance.
Referring to fig. 1, in some embodiments, a temperature sensor is disposed in each of the first water tank 5 and the third water tank 7 for detecting the temperature of the circulating water in the first water tank 5 and the third water tank 7. The speed regulation water pump 2 is connected with the flowmeter arranged on the water pipe of the third water tank 7, and is used for detecting the flow and the flow speed in the water pipe, controlling the on-off of the first electromagnetic valve 8 and the second electromagnetic valve 9 in time, ensuring that the circulating water in the third water tank 7 is controlled in a constant temperature range, and enabling the high-power gap laser to work normally.
Referring to fig. 1, in some embodiments, during use, the first water tank 5 and the second water tank 6 have a volume a, and are filled with circulating water, the third water tank 7 has a volume B, and the volume of the circulating water in the third water tank 7 is B-a.
Referring to fig. 1, in the cold storage and energy storage process, the first water tank 5 and the second water tank 6 are respectively filled with circulating water, and the volume of the circulating water of the third water tank 7 is B-a. The first circulating water pump 1 pumps circulating water from the first water tank 5 to enter the refrigerating unit 10, and the refrigerated circulating water enters the second water tank 6. Since the circulating water in the second water tank 6 is full, the circulating water in the second water tank 6 circulates the circulating water into the first water tank 5 through a water pipe whose top is communicated with the first water tank 5. Therefore, the circulating water in the first water tank 5 and the circulating water in the second water tank 6 are circulated through the refrigeration unit 10, and the temperatures of the circulating water in the first water tank 5 and the circulating water in the second water tank 6 are reduced. In some embodiments, the circulating water of the first water tank 5 and the circulating water of the second water tank 6 are controlled at 5-10 degrees celsius. In the process of cold storage and energy storage, the speed regulation water pump 2, the second circulating water pump 3 and the heat dissipation water pump 4 do not work, and the first electromagnetic valve 8 and the second electromagnetic valve 9 are closed.
Referring to fig. 1, when the high-power gap laser is in a working state, the heat dissipation water pump 4 is started, the water stored in the third water tank 7 can form a circulation to take away heat generated during the operation of the laser, and at this time, the circulation water in the third water tank 7 can rapidly raise the temperature because the circulation water absorbs the heat of the laser. Since laser operation needs to be performed in a constant temperature environment. The temperature sensor detects the temperature of the circulating water in the third water tank 7, when the temperature of the circulating water exceeds the temperature of a constant temperature environment, the second electromagnetic valve 9 is opened, the circulating water in the second water tank 6 is pumped into the third water tank 7 through the speed regulation work of the speed regulation water pump 2, and the water temperature of the third water tank 7 is reduced to the constant temperature environment for the laser to be used when being cooled. The first stage draws water from the second tank 6 and the first solenoid valve 8 is closed. In addition, the bottom of the first water tank 5 is connected with the top of the second water tank 6 through a water pipe, circulating water in the second water tank 6 is pumped out, and the circulating water in the first water tank 5 cannot automatically flow back to the second water tank 6.
Referring to fig. 1, the third tank 7 is increasingly circulating water, and as the second tank 6 approaches being evacuated, the third tank 7 is now near full, but not full, due to the design of the tanks, the capacity B > a, and the initial volume of the third tank 7 is less than B-a. After the circulating water in the second water tank 6 is pumped out, the flow meter detects that no water flows through the water pipe, the second electromagnetic valve 9 is closed, meanwhile, the first electromagnetic valve 8 is opened, and the circulating water in the first water tank 5 is continuously pumped into the third water tank 7 to enter the second stage of work. At this time, the circulating water is continuously pumped from the first water tank 5 to the third water tank 7, and the speed-regulating water pump 2 performs speed-variable regulation to constantly control the temperature of the third water tank 7. As the amount of water in the third water tank 7 increases, the water in the third water tank 7 overflows from the top, and the top of the third water tank 7 is connected to the bottom of the second water tank 6 through a water pipe, and the circulating water in the third water tank 7 overflows to flow into the second water tank 6, and the second water tank 6 is used to store the overflowing high-temperature water. Because the volumes of the first water tank 5 and the second water tank 6 are the same, the low-temperature water in the first water tank 5 continuously transmits cold energy to the third water tank 7, and the used high-temperature water flows back to the second water tank 6. Although the first water tank 5 is communicated with the second water tank 6, the circulating water does not flow into the first water tank 5 until the second water tank 6 is not full, so that the circulating water with cold stored in the first water tank 5 is not influenced by the high-temperature circulating water flowing back into the second water tank 6. This process may continue until the circulating water in the first water tank 5 is completely used up. At this point, the cold stored in the low-temperature circulating water in the first water tank 5 and the second water tank 6 is completely used up.
Referring to fig. 1, after the work is completed, the cold accumulation state is entered again by using the gap time. The second circulating water pump 3 operates to pump the high-temperature circulating water in the third water tank 7 back into the first water tank 5 until the first water tank 5 is completely filled with the circulating water. At this time, the initial state is basically returned, the first water tank 5 and the second water tank 6 are full of water, and a small amount of circulating water (slightly smaller than B-a) is left in the third water tank 7. And starting the first circulating water pump 1 and the refrigeration unit 10 to cool the circulating water in the first water tank 5 and the second water tank 6, in some embodiments, cooling the circulating water in the first water tank 5 and the second water tank 6 to 5-10 ℃, and then starting a new cycle.
Referring to fig. 1, the maximum continuous use time of the heat dissipation system of the high-power gap laser is determined by the stored cold capacity of the circulating water with the cold capacity stored in the first water tank 5 and the second water tank 6, but it is not required that all the energy in the first water tank 5 and the second water tank 6 is used up. If the high-power gap laser is operated when the cold storage capacity of the first and second water tanks 5 and 6 is only partially used, the water in the third water tank 7 is only required to be pumped back to the first water tank 5. Then the first circulating water pump 1 and the refrigeration unit 10 start to work, and the next circulation can be entered. The energy of the circulating water which is not used up in the first water tank 5 and the second water tank 6 and stores the cold energy still exists, and can still be used in the next cycle.
Referring to fig. 1, most of the existing high-power lasers are cooled in real time by a refrigeration unit 10, and the high-power gap laser of the scheme generates circulating water with cold energy in advance, and then provides constant-temperature water (25 ℃) for cooling the laser in a mode of neutralizing the circulating water (10 ℃) with the cold energy, so that the problem that a water cooler of the high-power laser is too large is solved, and a space is replaced by the time of gap type operation. Because the temperature is not reduced in real time, the refrigeration unit 10 can be designed to be very small and exquisite, for example, 10KW generates heat and works for 10 seconds, the refrigeration system which can become 1KW works for 100 seconds to replace the heat, and the cold is stored in the circulating water which stores the cold. The overall volumetric size and weight can be much smaller than conventional machines, while the power required to power the heat dissipation system is reduced and the overall size of the refrigeration unit 10 is reduced.
Referring to fig. 1, in the conventional cooling method for low-temperature water neutralization, a general design is that 2 water tanks, for example, 10L of water in each of a first water tank 5 and a second water tank 6 are used, 10L of water in the first water tank 5 of a water storage tank is completely cooled by 10 ℃ in an energy storage state, and when the cooling device is used, the first water tank 5 is gradually pumped into the second water tank 6 until the use is completed, and the volume of the water tank of the whole machine is 20L. This scheme design is through distinctive design, changes into 3 water tanks, is first water tank 5, second water tank 6, third water tank 7 respectively, corresponds above-mentioned case, and 10L's water storage tank decomposes into two 5L's first water tank 5, second water tank 6, and the water tank third water tank 7 of water can design into 5.5L, because the storage of middle water storage tank can come into use high-temperature water at once after using again. The whole machine is in the water tank volume design, and the whole water tank volume has reduced about 1/4 to make whole cooling system's volume reduce.
Referring to fig. 1, the heat dissipation system can be conveniently moved and used after being miniaturized and lightened, and the storage battery can be powered by the miniature direct current compressor, so that the heat dissipation system has obvious advantages for the moving requirement of special functions. For example, when the high-power gap laser attacks the unmanned aerial vehicle, the heat dissipation system is convenient to move and carry after being miniaturized, the whole system is convenient to move to a height control point and the like, and the high-power gap laser plays a role. Meanwhile, the small-sized helicopter or other onboard or vehicle-mounted helicopter is also facilitated.
Fig. 2 is a schematic flow chart of a cold storage and energy storage state in a method for using a heat dissipation system of a high-power gap laser according to an embodiment of the present application.
