Description

Technical Field

[0001] This invention relates to the field of cold storage technology, and particularly to an ice storage device for cooling a high-power laser using a gas-liquid two-phase flow. Background Technology

[0002] Lasers and radar devices typically operate in an intermittent mode, meaning they run for a period of time, then stop, and then restart after a certain interval, repeating this process. The sum of the laser's operating time and the interval between restarts is called an operating cycle. High-power lasers generate a significant amount of heat during operation, requiring thermal management using devices such as cooling plates. The purpose of thermal control is to dissipate the heat generated during laser operation while simultaneously ensuring that the temperature fluctuations on the laser surface remain within a suitable range; otherwise, the laser's output accuracy and the stability of the equipment's operation will be affected.

[0003] Considering the intermittent operation mode of lasers and to minimize equipment energy consumption, existing thermal control technologies mostly adopt a single-phase cold storage mode. The main approach is to configure a large cold storage tank. When the laser is working, a pump drives the coolant to be supplied to the laser heat sink. The coolant absorbs the waste heat from the laser's operation, heats up, and then flows into the cold storage tank. During the intervals when the laser is off, a compression refrigeration system is used to lower the temperature of the coolant in the cold storage tank to a lower value, and this process is repeated.

[0004] While current cold storage devices can control the temperature of lasers, when the laser power is high, a large cold water tank is often required, making the entire laser equipment bulky. In addition, during operation, uneven distribution of the two-phase flow is prone to occur, resulting in low heat transfer efficiency, local temperature rise, and difficulty in controlling the laser temperature. At the same time, the ice layer in the cold storage is prone to sticking together, affecting the heat transfer efficiency of the two-phase flow and resulting in high energy consumption. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of large space occupation, low heat transfer efficiency and high energy consumption of ice storage devices in the prior art, and to propose an ice storage device for gas-liquid two-phase flow cooling of high-power lasers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ice storage device for gas-liquid two-phase flow cooling of a high-power laser includes a refrigerator and further includes: fins symmetrically and fixedly connected inside the refrigerator for storing ice water between two sets of fins; two-phase flow tube boxes symmetrically and fixedly connected to the side wall of the refrigerator, wherein one set of the two-phase flow tube boxes is connected to the refrigerator by a two-phase flow inlet pipe and a two-phase flow outlet pipe, and a two-phase flow copper pipe is connected between the two sets of the two-phase flow tube boxes; wherein a turbulence mechanism is provided between the two-phase flow inlet pipe and the two-phase flow tube box to ensure uniform mixing of the two-phase flow within the two-phase flow tube box; and a refrigerant inlet pipe and a refrigerant outlet pipe symmetrically arranged inside the refrigerator, with a refrigerant copper pipe connecting the refrigerant inlet pipe and the refrigerant outlet pipe.

[0008] To facilitate cooling of the water inside the refrigerator, preferably, the bottom end of the refrigerant inlet pipe is located in the lower part of the refrigerator, the bottom end of the refrigerant outlet pipe is located in the upper part of the refrigerator, the refrigerant copper pipe extends from between the fins and the two-phase flow tube box to between the two sets of fins, and the refrigerant copper pipe is arranged in an "S" shape, with the top ends of the refrigerant inlet pipe and the refrigerant outlet pipe extending to the outside of the refrigerator.

[0009] To reduce energy consumption, preferably, the turbulence mechanism includes a fixed plate fixedly connected inside the two-phase flow inlet pipe. A rotating shaft is rotatably connected to the side of the fixed plate away from the two-phase flow pipe box. A water wheel and a drive bevel gear are fixedly connected to the rotating shaft. A connecting shaft is rotatably connected to the side wall of the two-phase flow inlet pipe. A driven bevel gear that meshes with the drive bevel gear is fixedly connected to the end of the connecting shaft. A drive wheel is fixedly connected to the side of the connecting shaft away from the driven bevel gear. The two-phase flow inlet pipe and the two-phase flow outlet pipe are located above and below the outer wall of the refrigerator, respectively. A pressure conveying assembly is provided inside the two-phase flow pipe box.

[0010] To improve the heat transfer effect of the two-phase flow, the two-phase flow tube box is further provided with a partition plate fixedly connected inside, which is used to divide the two-phase flow tube box into multiple sets of sealed cavities. The bottom of the sealed cavity on the side closer to the two-phase flow inlet pipe is connected to the top of the sealed cavity on the other side through a two-phase flow copper pipe, and the bottom of the sealed cavity on the side farther away from the two-phase flow inlet pipe is connected to the top of the sealed cavity on the other side through a two-phase flow copper pipe.

[0011] To further improve the uniformity of the two-phase flow distribution, the pressure conveying assembly includes a reciprocating screw rotatably connected within the two-phase flow tube box. The top end of the reciprocating screw extends to the outside of the two-phase flow tube box, and a driven wheel is fixedly connected to the top end of the reciprocating screw. A belt is sleeved between the driven wheel and the drive wheel. A sealing plate is provided on the reciprocating screw, and a through hole is provided on the sealing plate. A baffle matching the through hole is rotatably connected to the bottom of the sealing plate. A spring is fixedly connected between the baffle and the sealing plate. A compression cylinder is fixedly connected between the bottom of the sealing plate and the partition or the bottom of the two-phase flow tube box.

[0012] To further prevent ice bridging in the ice layer inside the refrigerator, multiple sets of aeration discs are fixedly connected to the bottom of the refrigerator. The aeration discs are connected to the exhaust port of the compressed cylinder through a pipe, and are used to agitate the ice layer inside the refrigerator in the form of bubbles through the aeration discs.

[0013] To improve the heat transfer effect of the two-phase flow and reduce the waste of cold air, the top of the fins is further fixedly connected to a cover plate that matches the interior of the refrigerator. The cover plate is connected to a vent pipe, which is connected to the compression cylinder through a pipe.

[0014] To further prevent ice from damaging the fins, a pressure relief pipe connected to the refrigerator is fixedly connected to the cover plate. The bottom end of the pressure relief pipe extends to the bottom of the refrigerator, and the top end of the pressure relief pipe penetrates the cover plate.

[0015] To facilitate the replacement of cooling water, preferably, a drain pipe is also included that connects to the lower side wall of the refrigerator, the drain pipe extending from the side wall of the refrigerator to between the two sets of fins.

[0016] To improve the heat transfer effect and efficiency of the two-phase flow, preferably, the two-phase flow copper tube and the refrigerant copper tube are arranged in an array between the fins, and the two-phase flow copper tube and the refrigerant copper tube are arranged in a transverse cross configuration.

[0017] Compared with the prior art, the present invention provides an ice storage device for gas-liquid two-phase flow cooling of high-power lasers, which has the following beneficial effects:

[0018] 1. This ice storage device for gas-liquid two-phase flow cooling of a high-power laser can cool the cooling water between two sets of fins until the water is frozen through the refrigerant inlet pipe, refrigerant outlet pipe and refrigerant copper pipe. This avoids the need to frequently turn on the cold storage device when the laser is working. While ensuring that the temperature fluctuation of the laser surface is within the normal range, it can also reduce the energy consumption of the equipment.

[0019] 2. The ice storage device for cooling gas-liquid two-phase flow of this high-power laser uses a turbulence mechanism driven by the flow of the two-phase flow in the two-phase flow inlet pipe to intermittently pressurize the liquid in the two-phase flow tube box. On the one hand, it can prevent the gas phase from accumulating in the pipe and the two-phase flow tube box, and on the other hand, it can prevent the gas and liquid phases from separating, thereby improving the uniformity of the two-phase flow and thus improving the sensing efficiency of the two-phase flow.

[0020] 3. The ice storage device for cooling gas-liquid two-phase flow of this high-power laser delivers compressed gas to the aeration plate through the turbulence mechanism to disturb the ice layer in the storage refrigerator to prevent the ice layer from sticking together. In addition, after the ice layer is cooled down, it will flow back to the two-phase flow box through the vent pipe, which improves the utilization rate of the cold air and the heat transfer efficiency of the two-phase flow.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention can overcome the problems of large space occupation, low heat transfer efficiency, and high energy consumption of ice storage devices. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Example:

[0033] Reference Figures 1-7 An ice storage device for gas-liquid two-phase flow cooling of a high-power laser includes a refrigerator 1, and further includes: fins 2, symmetrically fixedly connected inside the refrigerator 1, for storing ice water between two sets of fins 2; two-phase flow tube boxes 3, symmetrically fixedly connected to the side wall of the refrigerator 1, wherein one set of two-phase flow tube boxes 3 is connected to the refrigerator 1 by a two-phase flow inlet pipe 4 and a two-phase flow outlet pipe 5, and a two-phase flow copper pipe 28 is connected between the two sets of two-phase flow tube boxes 3; wherein a turbulence mechanism is provided between the two-phase flow inlet pipe 4 and the two-phase flow tube box 3 to ensure uniform mixing of the two-phase flow in the two-phase flow tube box 3; a refrigerant inlet pipe 7 and a refrigerant outlet pipe 8, symmetrically arranged inside the refrigerator 1, and a refrigerant copper pipe 9 is connected between the refrigerant inlet pipe 7 and the refrigerant outlet pipe 8.

[0034] In this embodiment, when the device is in use, water is first injected between the two sets of fins 2 inside the refrigerator 1. Then, refrigerant is injected through the refrigerant inlet pipe 7 to cool the water inside the refrigerator 1. After cooling, the refrigerant is discharged through the refrigerant outlet pipe 8 and flows back to the refrigeration system. This cycle continues until the water inside the refrigerator 1 freezes into ice. When the laser is working, a high-temperature pump drives the two-phase flow mixture to flow into the two-phase flow tube box 3 through the two-phase flow inlet pipe 4. At the same time, the two-phase flow mixture in the two-phase flow tube box 3 is intermittently compressed by the turbulence mechanism, causing the gas phase at a higher position to flow into the liquid phase, making the gas and liquid phases mix more evenly, thereby improving the heat transfer efficiency of the two-phase flow mixture. The intermittent compression... The gas is transported from the bottom ice layer to the interior of the refrigerator 1, disturbing the water layer inside the refrigerator 1 and preventing the ice layer from sticking together. The gas, cooled by the ice layer, flows back to the two-phase flow tube box 3 through the vent pipe 10. This improves the utilization rate of the cold air and the heat transfer efficiency of the two-phase flow mixture. Furthermore, the two-phase flow mixture is transported from one side of the two-phase flow tube box 3 and the two-phase flow copper pipe 28 to the other side of the two-phase flow tube box 3. During this process, the ice layer cools the two-phase flow mixture. Then it flows back to the initial two-phase flow tube box 3. This cycle is repeated to achieve temperature control of the two-phase flow mixture. Finally, it is discharged from the two-phase flow outlet pipe 5 to cool the laser.

[0035] Reference Figures 2-4 The bottom end of the refrigerant inlet pipe 7 is located in the lower part of the refrigerator 1, and the bottom end of the refrigerant outlet pipe 8 is located in the upper part of the refrigerator 1. The refrigerant copper pipe 9 extends from between the fins 2 and the two-phase flow pipe box 3 to between the two sets of fins 2, and the refrigerant copper pipe 9 is arranged in an "S" shape. The top ends of the refrigerant inlet pipe 7 and the refrigerant outlet pipe 8 extend to the outside of the refrigerator 1.

[0036] In this embodiment, after the refrigerant enters the refrigerant copper pipe 9 through the refrigerant inlet pipe 7, it gradually flows upward from the bottom of the refrigerator 1 and is finally discharged through the refrigerant outlet pipe 8. The symmetrical pipe arrangement on both sides can ensure uniform freezing at the same level, ensuring that the water in the refrigerator 1 freezes from bottom to top, and avoiding damage to the refrigerator 1 due to the increased volume of water after freezing.

[0037] Reference Figure 4 and Figure 6The turbulence mechanism includes a fixed plate 12 fixedly connected inside the two-phase flow inlet pipe 4. A rotating shaft 13 is rotatably connected to the side of the fixed plate 12 away from the two-phase flow pipe box 3. A water wheel 14 and a drive bevel gear 15 are fixedly connected to the rotating shaft 13. A connecting shaft 16 is rotatably connected to the side wall of the two-phase flow inlet pipe 4. A driven bevel gear 17 that meshes with the drive bevel gear 15 is fixedly connected to the end of the connecting shaft 16. A drive wheel 18 is fixedly connected to the side of the connecting shaft 16 away from the driven bevel gear 17. The two-phase flow inlet pipe 4 and the two-phase flow outlet pipe 5 are located above and below the outer wall of the refrigerator 1, respectively. A pressure conveying assembly is provided inside the two-phase flow pipe box 3.

[0038] In this embodiment, when the high-temperature two-phase flow mixture flows into the two-phase flow box 3 through the two-phase flow inlet pipe 4, it drives the water wheel 14 to rotate, thereby driving the connecting shaft 16 to rotate through the driven bevel gear 15 and the driven bevel gear 17. During this process, the water wheel 14 can also stir the two-phase flow mixture to avoid the two-phase flow mixture from stratifying in the two-phase flow inlet pipe 4, and further improve the mixing effect of the gas phase and the liquid phase.

[0039] Reference Figure 4 The two-phase flow tube box 3 is fixedly connected to a partition 19, which is used to divide the two-phase flow tube box 3 into multiple sets of sealing cavities. The bottom of the sealing cavity on the side closer to the two-phase flow inlet pipe 4 is connected to the top of the sealing cavity on the other side through a two-phase flow copper pipe 28. The bottom of the sealing cavity on the side farther from the two-phase flow inlet pipe 4 is connected to the top of the sealing cavity on the other side through a two-phase flow copper pipe 28.

[0040] In this embodiment, the partition 19 divides the two-phase flow tube box 3 into multiple sets of sealed cavities. When the high-temperature two-phase flow mixture flows into one set of sealed cavities, it flows through the two-phase flow copper pipe 28 to another two-phase flow tube box 3. The high-temperature two-phase flow mixture circulates in an "S" shape within the two sets of two-phase flow tube boxes 3, thereby achieving an efficient cooling effect on the two-phase flow mixture and completing the temperature control of the two-phase flow mixture.

[0041] Reference Figure 4 and Figure 7 The pressurizing assembly includes a reciprocating screw 20 rotatably connected inside the two-phase flow tube box 3. The top end of the reciprocating screw 20 extends to the outside of the two-phase flow tube box 3, and a driven wheel 26 is fixedly connected to the top end of the reciprocating screw 20. A belt 27 is sleeved between the driven wheel 26 and the drive wheel 18. A sealing plate 21 is provided on the reciprocating screw 20. A through hole 22 is opened on the sealing plate 21. A baffle 23 matching the through hole 22 is rotatably connected to the bottom of the sealing plate 21. A spring piece 24 is fixedly connected between the baffle 23 and the sealing plate 21. A compression cylinder 25 is fixedly connected between the bottom of the sealing plate 21 and the partition 19 or the bottom of the two-phase flow tube box 3.

[0042] In this embodiment, when the connecting shaft 16 rotates, it drives the driven wheel 26 to rotate via the drive wheel 18 and belt 27, thereby driving the reciprocating screw 20 to rotate, which in turn drives the sealing plate 21 to move up and down reciprocally within the two-phase flow tube box 3. It should be explained that, since the density of the gas phase in the two-phase flow mixture is less than that of the liquid phase, when it flows into the two-phase flow tube box 3, the gas phase is located above the liquid phase. When the sealing plate 21 moves downward, it can increase the pressure of the two-phase flow mixture flowing into the two-phase flow copper tube 28. When the sealing plate 21 moves upward, it can inject the gas above into the liquid phase below at high speed, thereby making the gas and liquid phases mix more evenly and improving the heat transfer efficiency of the two-phase flow mixture.

[0043] Reference Figures 4-5 It also includes multiple sets of aeration discs 29 fixedly connected to the bottom of the refrigerator 1. The aeration discs 29 are connected to the exhaust port of the compressed cylinder 25 through a pipe, and are used to agitate the ice layer inside the refrigerator 1 in the form of bubbles through the aeration discs 29.

[0044] In this embodiment, when the sealing plate 21 moves up and down reciprocally in the two-phase flow tube box 3, it will intermittently drive the compression cylinder 25 to extend or retract. When the compression cylinder 25 retracts, it will transport the compressed gas to the aeration plate 29. The gas will flow to the bottom of the refrigerator 1 in the form of bubbles, disturbing the ice layer in the refrigerator 1 to avoid the ice layer from sticking together, and further improving the heat transfer efficiency of the two-phase flow mixture.

[0045] Reference Figures 1-4 The top of the fin 2 is fixedly connected to a cover plate 30 that matches the interior of the refrigerator 1. A vent pipe 10 is connected to the cover plate 30. The vent pipe 10 is connected to the compression cylinder 25 through a pipe.

[0046] In this embodiment, after the ice layer is disturbed, the gas will flow to the top of the refrigerator 1. At this time, the high-temperature gas is in a low-temperature state. When the compression cylinder 25 extends, the low-temperature gas can be extracted, thereby cooling the two-phase flow mixture in the two-phase flow tube box 3. On the one hand, it can improve the utilization rate of cold air and reduce the energy consumption of the equipment. On the other hand, it can improve the heat transfer efficiency of the two-phase flow mixture, thereby improving the temperature control effect of the laser.

[0047] Reference Figures 1-3 A pressure relief pipe 11 connected to the refrigerator 1 is fixedly connected to the cover plate 30. The bottom end of the pressure relief pipe 11 extends to the bottom of the refrigerator 1, and the top of the pressure relief pipe 11 penetrates the cover plate 30.

[0048] In this embodiment, since the phase change of water during ice storage or melting will cause volume change, if the system is completely sealed, high pressure may be generated due to volume expansion, which may cause the side wall, fins 2 or pipes of the ice storage refrigerator 1 to rupture. By releasing the excessive pressure in time, equipment damage can be avoided. At the same time, it can also be avoided that a local vacuum is formed in the ice layer during ice melting, which may cause the equipment to collapse.

[0049] Reference Figure 1 It also includes a drain pipe 6 connected to the lower side wall of the refrigerator 1, which extends from the side wall of the refrigerator 1 to between the two sets of fins 2.

[0050] In this embodiment, since dissolved oxygen, chloride ions, calcium ions, etc. in the water can cause corrosion of metal pipes or generate scale, reduce the heat transfer efficiency of the equipment, and shorten the service life of the equipment, it is necessary to replace the water in the storage tank 1 regularly through the drain pipe 6.

[0051] Reference Figure 2 and Figure 5 Two-phase flow copper tube 28 and refrigerant copper tube 9 are arranged in an array between fins 2, and the two-phase flow copper tube 28 and refrigerant copper tube 9 are arranged in a transverse cross configuration.

[0052] In this embodiment, by arranging the two-phase flow copper pipe 28 and the refrigerant copper pipe 9 in an array and cross arrangement between the fins 2, the temperature of cooling and releasing in the refrigerator 1 can be ensured to be uniform.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
