Description

Technical Field

[0001] This invention belongs to the field of laser equipment cooling, specifically a cooling system and a laser device using the same. Background Technology

[0002] With the widespread application of laser technology in industrial processing, medical treatment, scientific research and other fields, the power density of lasers continues to increase, generating a large amount of heat during operation. If the heat cannot be dissipated in time, it will cause the temperature of core components such as laser gain medium and pump source to become too high, leading to problems such as wavelength drift, output power attenuation, and shortened lifespan, seriously affecting the stability and reliability of laser equipment.

[0003] Traditional laser cooling methods mainly include: ① air cooling (low heat dissipation efficiency, suitable for low-power lasers); ② conventional water cooling (requires additional power components such as water pumps and heat exchangers, the system is complex, energy consumption is high, and there is a risk of leakage); ③ phase change cooling (some solutions rely on external force to drive circulation, or the gas-liquid separation is incomplete and the reflux is not smooth, resulting in insufficient cooling stability). Therefore, a cooling system and laser equipment using it are proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: traditional cooling systems require additional power components such as water pumps and motors, resulting in high energy consumption, complex structure, high maintenance costs, and the risk of leakage; In existing phase change cooling schemes, gas-liquid separation is incomplete, and the entrainment of liquid water droplets in the vapor can easily lead to a decrease in condensation efficiency. Furthermore, the reflux path design is unreasonable, making it impossible to achieve continuous and stable self-circulation. The heat sink is not well-suited for use with circular lasers, with a small contact area and high thermal resistance, resulting in low heat transfer efficiency and an inability to quickly remove heat from the laser core. The inner layer of water near the laser inside the heat sink has a higher temperature. If it cannot be removed in time, it will cause local heat accumulation and reduce the heat sink's continuous heat absorption capacity. The condensation system has a limited heat dissipation area and lacks an efficient gas-liquid separation structure, resulting in a slow steam liquefaction rate and affecting the overall cooling cycle efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cooling system and a laser device using the same, comprising a cooling mechanism, a condenser and a pump, wherein the cooling mechanism comprises a base plate, a heat sink, a first connecting pipe, a heat dissipation tower, a steam collection platform and a second connecting pipe, wherein a connecting channel is provided on the inner side of the base plate, a heat sink is provided at one end of the base plate and a heat dissipation tower is provided at the other end of the base plate, one end of the connecting channel is connected to the cavity of the heat sink, and the other end of the connecting channel is connected to the heat dissipation tower through the first connecting pipe, wherein the middle part of the heat dissipation tower is higher than the top of the heat sink; A liquid pump is installed on the upper part of the heat sink, and a steam collection platform is installed on the upper side of the heat sink. A conveyor is installed at the top of the steam collection platform, which connects the liquid pump and the condenser. The condenser is connected to the top of the cooling tower, realizing a closed-loop cooling cycle design. The heat transfer fluid can be circulated without external power, improving the system's operational autonomy. As a preferred technical solution for a cooling system and laser equipment using it, the volume of the top of the cooling tower is larger than that of the bottom. The bottom of the cooling tower is provided with three evenly distributed support frames. The bottom of the support frames is fixedly connected to the upper side of the base plate, which increases the heat dissipation storage space while ensuring support stability. The gravity difference is used to promote the return of the heat transfer fluid and improve the circulation efficiency. As a preferred technical solution for a cooling system and laser equipment using it, the conveying component includes an ejector pump, a connecting pipe three, and a one-way valve. The top of the connecting pipe two is equipped with a pipe two, and the end of the pipe two away from the steam collection platform is equipped with an ejector pump. One end of the ejector pump is connected to the liquid pump via the connecting pipe three, and the other end of the ejector pump is equipped with a one-way valve, which is connected to the condenser. The ejector pump generates a stable suction effect, and the one-way valve prevents backflow of the medium, ensuring the uniqueness and continuity of the circulation direction. As a preferred technical solution for a cooling system and laser equipment using it, the liquid extractor includes a liquid collecting arc plate, a rigid liquid suction tube, and a U-shaped connecting tube. A liquid collecting arc plate is set on each of the two outer sides of the heat sink, and several rigid liquid suction tubes are set on the inner side of the liquid collecting arc plate. The rigid liquid suction tubes extend into the inner cavity of the heat sink, with the end of the rigid liquid suction tube away from the liquid collecting arc plate close to the inner ring of the heat sink cavity. The inner cavity of the heat sink is an annular cavity, and the heat sink penetrates three-quarters of the annular cavity. The liquid collecting arc plate is arc-shaped, and the corresponding arc is one-sixth of the circumference. It accurately extracts the high-temperature heat-conducting liquid from the inner ring of the heat sink, avoids local heat accumulation, and improves the heat absorption efficiency of the heat sink. As a preferred technical solution for a cooling system and laser equipment using it, the conveying component includes a connecting channel one and a connecting channel two. Connecting channel one is provided on one side of the inner side of the base plate, and connecting channel two is provided on the other side of the inner side of the base plate. Connecting channel one is connected to the inner cavity of the heat sink, and connecting channel two is connected to connecting pipe one. Connecting hole one is provided at the end of connecting channel one away from the heat sink, and connecting hole one is also provided at the end of connecting channel two away from connecting pipe one. A slow-release chamber is provided inside the slow-release seat, and two connecting holes two are provided on the lower side of the slow-release chamber. Connecting hole one and connecting hole two correspond one-to-one. A capillary layer is provided in the middle of the slow-release chamber, and connecting holes two are arranged on both sides of the capillary layer. The capillary layer realizes the stable delivery of heat-conducting liquid, and the slow-release chamber buffers pressure fluctuations to ensure the stability of liquid flow. As a preferred technical solution for cooling systems and laser equipment using them, the side of the liquid collecting arc plate away from the rigid liquid suction pipe is connected to the connecting pipe three-way connection, realizing seamless connection between the liquid suction and delivery pipelines, reducing the resistance to medium flow, and improving the synergistic efficiency of liquid suction and delivery. As a preferred technical solution for a cooling system and laser equipment using it, the condenser includes a condenser cylinder, a liquid collection cylinder, and a strip cylinder. One end of the condenser cylinder is connected to a one-way valve, and the end of the condenser cylinder away from the one-way valve is connected to the liquid collection cylinder. A strip cylinder is provided on the lower side of the liquid collection cylinder, and the bottom end of the strip cylinder is connected to the middle of the upper side of the heat dissipation tower. This realizes an integrated design of steam condensation, liquid collection, and reflux, shortens the reflux path, and improves the condensation recovery efficiency. As a preferred technical solution for a cooling system and laser equipment using it, the condenser cylinder is uniformly provided with several heat dissipation grids on its outer periphery, and several uniformly distributed micro-holes with a diameter of 0.3mm are provided between the inner side of the condenser cylinder and the heat dissipation grids. The heat dissipation grids increase the heat dissipation area, and the micro-holes accelerate gas-liquid separation, thereby synergistically improving the condensation efficiency. As a preferred technical solution for a cooling system and laser equipment using it, the inner side of the condenser cylinder has several guide plates arranged in a uniform annular array. The guide plates are uniformly distributed with φ0.3mm micropores, and the edges of the micropores are chamfered. The surface of the guide plates is coated with a hydrophilic ceramic coating to enhance the adsorption force on water droplets. The annular array of guide plates achieves 360° uniform separation, and the hydrophilic coating accelerates the aggregation of water droplets, improving the gas-liquid separation efficiency to over 95%. As a preferred technical solution for a cooling system and laser equipment using it, a circular groove is provided in the middle of the heat sink, which is inserted into the laser. The laser equipment includes a cooling system and a laser. The top end of the connecting pipe three is connected to the contraction section of the ejector pump. A flow divider is provided at the end of the guide plate near the strip cylinder. The central axis of the flow divider coincides with the central axis of the condenser cylinder. The circular groove achieves precise matching with the laser, and the flow divider ensures uniform distribution of the medium, improving the overall adaptability and operational stability of the system.

[0007] The beneficial effects of the cooling system and laser equipment using the present invention are as follows: self-driven circulation without external power: the heat generated by the laser itself vaporizes the heat-conducting liquid to produce steam, which is driven by the suction effect of the ejector pump. No additional power components such as water pumps and motors are required. The energy consumption is low and the structure is simplified. Moreover, the circulation power is adaptive to the heat generated by the laser. The more heat generated, the greater the amount of steam and the stronger the circulation.

[0008] Compatible with circular lasers, high thermal conductivity: The heat sink is designed as a ring-shaped cavity structure with a circular groove, which can be precisely inserted into the circular laser and fit 360° without dead angles; at the same time, the high-temperature liquid inside the ring-shaped cavity of the heat sink is removed by a rigid liquid suction tube to avoid local heat accumulation and significantly improve the heat absorption capacity and heat transfer efficiency of the heat sink.

[0009] Thorough gas-liquid separation and strong circulation stability: The condenser is equipped with a ring array of guide plates with micropores, and the guide plates are coated with a hydrophilic ceramic coating. Combined with the heat dissipation grid around the condenser cylinder, it achieves a triple effect of "inertial impaction separation, capillary adsorption separation, and efficient heat dissipation liquefaction". The gas-liquid separation efficiency is high, and the steam avoids water droplets from affecting the condensation effect. The separated liquid water flows back to the heat dissipation tower through the liquid collection cylinder and the ribbon cylinder to form a closed loop circulation with no loss of working fluid.

[0010] High heat dissipation efficiency and stable cooling effect: The heat dissipation tower adopts a "large at the top and small at the bottom" structural design, and the top is higher than the heat sink, using the gravity difference to assist the return of the heat transfer liquid; multiple heat dissipation grids are set around the condenser cylinder to increase the heat dissipation area. Combined with the efficient separation and liquefaction effect of the guide plate, the steam is quickly cooled into liquid water, ensuring that the temperature of the core components of the laser is stable within a reasonable range, avoiding power attenuation and shortened life.

[0011] Compact structure and easy installation and maintenance: The cooling mechanism, condenser and liquid pump are integrated into one design. All components are quickly connected through connecting pipes and one-way valves, without complicated piping. The heat dissipation tower is fixed to the base plate by the support frame. The heat sink and laser are plugged in for easy disassembly and maintenance. The overall structure occupies little space and is suitable for the installation needs of laser equipment in different scenarios. Attached Figure Description

The condenser 200 is connected to the top of the heat dissipation tower 106, realizing a closed-loop cooling cycle design. The heat transfer liquid can be circulated without external power, improving the system's operational autonomy. The volume of the top of the cooling tower 106 is larger than that of its bottom. Three evenly distributed support frames 110 are installed at the bottom of the cooling tower 106. The bottom of each support frame 110 is fixedly connected to the upper side of the base plate 101, increasing the heat dissipation storage space while ensuring support stability. Gravity difference is used to promote the return flow of the heat transfer fluid, improving circulation efficiency. The ejector pump is a Venturi tube structure.

[0019] The conveying components include an ejector pump 111, a connecting pipe 3 109, and a check valve 104. A connecting pipe 2 108 is provided at the top of the steam collection platform 107. An ejector pump 111 is provided at the end away from the steam collection platform 107. One end of the ejector pump 111 is connected to the liquid pump 300 through the connecting pipe 3 109. The other end of the ejector pump 111 is provided with a check valve 104. The check valve 104 is connected to the condenser 200. The ejector pump generates a stable suction effect, and the check valve prevents the medium from flowing back, ensuring the uniqueness and continuity of the circulation direction. The liquid extractor 300 includes a liquid collecting arc plate 301, a rigid liquid suction tube 302, and a U-shaped connecting tube 303. A liquid collecting arc plate 301 is provided on each of the two outer sides of the heat sink 102. Several rigid liquid suction tubes 302 are provided on the inner side of the liquid collecting arc plate 301. The rigid liquid suction tubes 302 extend into the inner cavity of the heat sink 102. The end of the rigid liquid suction tube 302 away from the liquid collecting arc plate 301 is close to the inner ring of the heat sink 102 cavity. The inner cavity of the heat sink 102 is a circular annular cavity. The heat sink 102 penetrates three-quarters of the circular annular cavity. The liquid collecting arc plate 301 is arc-shaped, and the corresponding arc is one-sixth of the circumference. It accurately extracts the high-temperature heat-conducting liquid from the inner ring of the heat sink, avoids local heat accumulation, and improves the heat absorption efficiency of the heat sink. The conveying component includes a first connecting channel 112 and a second connecting channel 113. The first connecting channel 112 is provided on one side of the inner side of the base plate 101, and the second connecting channel 113 is provided on the other side of the inner side of the base plate 101. The first connecting channel 112 is connected to the inner cavity of the heat sink 102, and the second connecting channel 113 is connected to the first connecting pipe 105. The end of the first connecting channel 112 away from the heat sink 102 is provided with a first connecting hole, and the end of the second connecting channel 113 away from the first connecting pipe 105 is also provided with a first connecting hole. The inner side of the slow-release seat 103 is provided with a slow-release chamber, and the lower side of the slow-release chamber is provided with two second connecting holes, with the first connecting hole and the second connecting hole corresponding one-to-one. The middle part of the slow-release chamber is provided with a capillary layer 114, and the second connecting holes are arranged on both sides of the capillary layer 114. The capillary layer realizes the stable delivery of the heat transfer fluid, and the slow-release chamber buffers pressure fluctuations to ensure the stability of the liquid flow. The side of the liquid collecting arc plate 301 facing away from the rigid liquid suction pipe 302 is connected to the connecting pipe 109, realizing seamless connection between the liquid suction and delivery pipelines, reducing the resistance to medium flow, and improving the synergistic efficiency of liquid suction and delivery. The condenser 200 includes a condenser cylinder 201, a liquid collecting cylinder 203, and a strip cylinder 204. One end of the condenser cylinder 201 is connected to a one-way valve 104, and the end of the condenser cylinder 201 away from the one-way valve 104 is connected to the liquid collecting cylinder 203. The strip cylinder 204 is provided on the lower side of the liquid collecting cylinder 203, and the bottom end of the strip cylinder 204 is connected to the middle of the upper side of the heat dissipation tower 106. This realizes the integrated design of steam condensation, liquid collection and reflux, shortens the reflux path and improves the condensation recovery efficiency. Several heat dissipation grids 202 are evenly arranged around the condenser cylinder 201. Several micro-holes with a diameter of φ0.3mm are evenly distributed between the inner side of the condenser cylinder 201 and the heat dissipation grids 202. The heat dissipation grids increase the heat dissipation area, and the micro-holes accelerate gas-liquid separation, thus synergistically improving the condensation efficiency. The inner side of the condenser 201 has several guide plates 205 arranged in a uniform annular array. The guide plates 205 have micropores of φ0.3mm evenly distributed on them, and the edges of the micropores are chamfered to reduce airflow resistance. The surface of the guide plates 205 is coated with a hydrophilic ceramic coating with a contact angle of <30°. The guide plates 205 are set at an angle to enhance the adsorption force on water droplets. The annular array of guide plates achieves 360° uniform separation. The hydrophilic coating accelerates the aggregation of water droplets, and the gas-liquid separation efficiency is increased to over 95%. The guide plates 205 are arranged in a uniform annular array along the inner wall of the condenser cylinder 201, and are inclined at an angle of 30°~40° to the horizontal plane and 50°~60° to the vertical plane. The high end of the guide plates faces the horizontal airflow inlet of the condenser cylinder, and the low end faces the liquid collection cylinder 203. After the horizontally entering mixed airflow of steam and droplets impacts the guide plates, the droplets are adsorbed by the hydrophilic coating and drip down into the liquid collection cylinder along the inclined direction of the plates, while the steam flows through the micropores of the guide plates and the gaps between the plates to the heat dissipation grid 202 on the outside of the condenser cylinder, thus achieving gas-liquid separation.

[0020] A circular groove is provided in the middle of the heat sink 102, which is connected to the laser. The laser equipment includes a cooling system and a laser. The top end of the connecting pipe 109 is connected to the contraction section of the ejector pump 111. A flow divider 206 is provided at one end of the guide plate 205 near the strip cylinder 204. The central axis of the flow divider 206 coincides with the central axis of the condenser cylinder 201. The circular groove achieves precise matching with the laser, and the flow divider ensures uniform distribution of the medium, improving the overall adaptability and operational stability of the system. The specific implementation method is as follows: The laser is inserted into the heat sink 102, and a heat-conducting liquid, such as water, is injected into the cooling tower 106. The liquid level in the inner cavity of the cooling tower 106 is located at four-fifths of the height. When the laser is working, it generates a large amount of heat. The heat is introduced into the inner cavity of the heat sink 102 through the heat sink 102. While the laser is being cooled, the water in the heat-conducting cavity of the heat sink 102 is heated. The water vapor generated by the heating in the heat sink 102 enters the steam collection platform 107. The water vapor enters the ejector pump 111 through the steam collection platform 107 and the connecting pipe 108. The water vapor then passes through the ejector pump 111, the one-way valve 104, and the condenser 200 to reach the cooling tower 106. During this process, the ejector pump 111 generates a suction effect, and the water vapor is drawn away by the connecting pipe 109. The water liquid near the inner side of the annular cavity of the heat sink 102 is injected into the inner cavity of the condenser cylinder 201 along with the water vapor. The mixture of water vapor and water liquid encounters the guide plate 205 and the micropores on the guide plate 205 and the condenser cylinder 201, which separates the water liquid and gas. The hydrophilic ceramic coating causes the water liquid to collect and drip to the bottom of the condenser cylinder 201. The gas entering the heat dissipation grid 202 can be significantly cooled. The rigid liquid suction pipe 302 draws away the relatively hotter liquid in the inner layer, improving the heat absorption capacity of the heat sink 102. The liquid is cooled after passing through the condenser cylinder 201 and reaches the top of the heat dissipation tower 106. The relatively cooler liquid at the bottom of the heat dissipation tower 106 enters the inner cavity of the heat sink 102 through the conveying component, so that the liquid in the heat sink 102 is renewed. Then the water vapor is cooled by encountering the inner wall of the heat dissipation grid 202; The entire process is powered by the heat generated by the laser itself, which can spontaneously form a cycle.

[0021] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0022] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
