Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, specifically to a laser chiller air-cooled system. Background Technology

[0002] In the process of laser emission and energy conversion, only 10% to 30% of the electrical energy in laser equipment is converted into effective laser energy, while the remaining 70% to 90% is converted into heat. This heat will be concentrated on core precision components such as laser head, resonant cavity, semiconductor pump source, and power supply. If it is not cooled in time and accurately, it will directly lead to equipment scrapping or processing failure. Moreover, the cooling requirements of laser components cannot be met by ordinary fans or tap water cooling.

[0003] Therefore, laser equipment often uses chillers for cooling. The core components of a chiller are a compressor, an air-cooled condenser, a throttling device, and an evaporator. These four components form a refrigerant closed loop through copper pipes. Most existing chillers are integrated, which makes them easy to install in various workshops and quickly meet the heat dissipation needs of laser equipment.

[0004] This integrated chiller is installed in a metal enclosure. By opening air vents on both sides of the enclosure and installing finned heat sinks on both sides inside the enclosure to form a V-shape, and also installing an exhaust fan on the top of the enclosure, it can draw ambient air into the enclosure and let it flow through the finned heat sinks, thereby achieving the purpose of air cooling.

[0005] With the fan positioned at the top of the enclosure and the vents located along the airflow paths on both sides, most of the outside air entering the enclosure from the sides is directly drawn away by the fan. This drawn-away airflow is insufficient to fully cover the fins of the finned heat sink, thus the heat dissipation effect needs improvement. Summary of the Invention

[0014] Preferably, one end of the pull rope is fixed to the protective frame, and positioning plates are fixed to the inner walls on both sides of the housing, with composite mesh fabric fixed to the bottom of the positioning plates.

[0015] Preferably, one end of the composite mesh passes through the water storage tank and is located inside the water storage tank.

In addition to filtering and removing dust from the outside air, the composite mesh cloth can further cool the outside air, thereby increasing the temperature difference between the outside air and the surface of the fins and copper tubes, and thus improving the heat dissipation efficiency of the fins and copper tubes.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-10 A laser chiller air-cooling system includes a chassis 1, a support column 101 fixed to the top of the chassis 1, a cross frame 102 fixed to the top of the support column 101, a housing 11 sleeved on the outside of the cross frame 102, ventilation frames 111 fixed on both sides of the housing 11, protective frames 24 fixed on both sides of the top of the housing 11, a motor 25 fixed to the top of the protective frame 24, the output shaft of the motor 25 passing through the protective frame 24 and having fan blades 26 fixed thereon.

[0035] Mounting brackets 3 are fixed to the top of both ends of the cross frame 102. Cylinders 31 are fixed inside the mounting brackets 3. Pressure rods 32 are fixed to the output shaft of the cylinders 31. First springs 33 are fixed to both sides of the mounting brackets 3. Limiting rings 4 are fixed to both sides of the top of both ends of the cross frame 102. Protective frames 41 are rotatably connected inside the limiting rings 4. Fins 42 are fixed inside the protective frames 41. Copper tubes 43 are fixed inside the fins 42. The two ends of the pressure rods 32 abut against the two protective frames 41.

[0036] A compressor 2 is fixed on the top of the chassis 1. A water pump 21 is connected to one side of the compressor 2 via a pipe. An integrated water tank 22 is connected to one side of the water pump 21 via a pipe. A control cabinet 23 is fixed on the top of the chassis 1, located on one side of the integrated water tank 22. A cabinet door is opened on the side of the housing 11 near the control cabinet 23, and a control switch 12 is installed on one side of the cabinet door. The control switch 12 is connected to the control cabinet 23 via a wire. A partition is provided on one side of the inner wall of the housing 11, and a filter 231 is fixed on the top of the partition. A double-pass pipe 201 is fixed on the top of the compressor 2. The two ends of the top of the double-pass pipe 201 are connected to two copper pipes 43 respectively. The inlet end of the filter 231 is connected to the copper pipe 43 via a pipe, and the outlet end of the filter 231 is connected to the integrated water tank 22 via a pipe.

[0037] During operation, the compressor 2, water pump 21, integrated water tank 22, 231 and motor 25 are started first by controlling switch 12.

[0038] After the high-temperature cooling water used for cooling the laser equipment is pumped back to the integrated water tank 22 and its internal evaporator by the water pump 21, the high-temperature cooling water is cooled by the evaporator. The high-temperature cooling water is then cooled by the refrigerant in the evaporator and enters the compressor 2. The compressor 2 then delivers the refrigerant into the interior of the copper tube 43. The motor 25 drives the fan blades 26 to rotate, and the fan blades 26 draw air from the interior of the housing 11, exhausting the heat from the fins 42 and the surface of the copper tube 43 to the outside of the housing 11. The cooled refrigerant is then throttled and depressurized through the pipes via 231 and the throttling device. The depressurized and cooled refrigerant is then discharged back into the evaporator in the integrated water tank 22. This ensures that the evaporator in the integrated water tank 22 can continuously exchange heat with the high-temperature cooling water in the integrated water tank 22 and the evaporator, and the low-temperature cooling water is then delivered back to the flow path of the laser equipment to cool the laser equipment.

[0039] The above describes the heat dissipation process of an air-cooled chiller in the prior art, and the throttling device is existing technology, so it will not be described again in this invention.

[0040] Specifically, in actual operation, when the motor 25 starts and drives the fan blades 26 to draw air into the interior of the housing 11, the outside air of the housing 11 enters the interior of the housing 11 through the ventilation frame 111. At this time, the control switch 12 controls the cylinder 31 to start and controls the mounting frame 3 to reciprocate the push-out and return strokes.

[0041] During the ejection process, the cylinder 31 drives the pressure rod 32 to be ejected, causing the pressure rod 32 to rise along the vertical direction of the cylinder 31. This reduces the pressure of the pressure rod 32 on the two protective frames 41, causing the protective frames 41 to flip towards the mounting bracket 3 under the action of the first spring 33. During the flipping process, the protective frame 41 drives the fins 42 and copper tubes 43 to flip synchronously, thereby changing the position of the fins 42 and copper tubes 43 inside the housing 11.

[0042] When the cylinder 31 returns, the cylinder 31 drives the pressure rod 32 to descend vertically along the cylinder 31, which in turn causes the pressure rod 32 to press the protective frames 41 on both sides, causing the two protective frames 41 to flip towards the ventilation frames 111 on both sides, and change their positions again.

[0043] By continuously changing the positions of the fins 42 and copper tubes 43, the fan blades 26 can draw air from the ventilation frame 111, allowing the fins 42 and copper tubes 43 to have more comprehensive contact with the outside air, thereby improving the air cooling effect of the fan blades 26 on the fins 42 and copper tubes 43.

[0044] Furthermore, during the flipping process of the fins 42 and the copper tube 43, dust and debris adhering to the surface of the fins 42 can be shaken off, thereby increasing the contact area between the fins 42 and the air, further improving the heat dissipation efficiency of the fins 42, and thus improving the overall heat dissipation efficiency of the laser equipment.

[0045] It should be noted that all devices in this invention are controlled by the combined control switch 12 and control cabinet 23. In the prior art, small air-cooled water chillers integrate the evaporator inside the integrated water tank 22, and this invention is the same. Therefore, no specific description of the evaporator is given.

[0046] Example 2: Water storage tanks 5 are provided inside both sides of the cross frame 102. Second springs 51 are fixed at the bottom of both ends of the water storage tanks 5. Rubber plates 52 are fixed at the top of the second springs 51. Pull rods 53 are fixed at the top of both ends of the rubber plates 52. Pull rods 53 pass through the water storage tanks 5, and pull ropes 54 are fixed at the top of the pull rods 53. One end of the pull ropes 54 is fixed to the protective frame 41.

[0047] Positioning plates 55 are fixed to the inner walls on both sides of the housing 11. Composite mesh 56 is fixed to the bottom of the positioning plates 55. One end of the composite mesh 56 passes through the water storage tank 5 and is located inside the water storage tank 5. Screws 57 are threaded to the surfaces on both sides of the housing 11. A positioning rod 571 is fixed to one end of the screw 57. The positioning rod 571 passes through the water storage tank 5 and abuts against the composite mesh 56.

[0048] Specifically, based on Embodiment 1, before starting all the equipment of the present invention, pure water is first injected into the two water storage tanks 5 through the water injection holes on the surface of the cross frame 102. Then, one end of the composite mesh 56 is inserted into the water storage tank 5. Next, the screw 57 and the positioning rod 571 are rotated and inserted into the chassis 1, so that the positioning rod 571 is inserted into the water storage tank 5. Then, the positioning rod 571 is used to press one end of the composite mesh 56 against the inner wall of the water storage tank 5.

[0049] Then, the screw 57 drives the positioning rod 571 to fix the bottom end of the composite mesh 56 to the inner wall of the water storage tank 5, so that the composite mesh 56 is stretched. Then, the stretched composite mesh 56 covers the ventilation frame 111. Then, under the action of capillary action, wait for 5-10 minutes, so that the pure water in the water storage tank 5 gradually wets the entire composite mesh 56.

[0050] Once the surface of the composite mesh fabric 56 is evenly wetted with pure water, the motor 25 can be started by the control switch 12. The motor 25 drives the fan blades 26 to draw air into the interior of the housing 11, allowing outside air to pass through the housing 11 first and then through the composite mesh fabric 56. Since the surface of the composite mesh fabric 56 is evenly wetted with pure water, the damp composite mesh fabric 56 intercepts and filters dust entering the housing 11, thereby reducing the probability of dust adhering to the surfaces of the fins 42 and copper tubes 43. This increases the contact area between the fins 42 and copper tubes 43 and the air, thus improving the air-cooling efficiency of the motor 25 and fan blades 26.

[0051] In summer, when the outside air temperature is too high, even if the outside air is drawn into the interior of the housing 11 by the motor 25 and the fan blades 26 and flows over the surface of the fins 42 and the copper tubes 43, the efficiency of the fins 42 and the copper tubes 43 will be reduced due to the room temperature or outdoor temperature of the outside air in summer.

[0052] Therefore, the pure water on the surface of the composite mesh 56 achieves a preliminary cooling effect, allowing ambient air to absorb heat through the pure water on the surface of the composite mesh 56 after passing through the housing 11 and the composite mesh 56. This allows the ambient air to be cooled before being drawn into the housing 11 by the motor 25 and the fan blades 26. Subsequently, the cooled ambient air flows over the surfaces of the fins 42 and the copper tube 43, further improving the heat dissipation efficiency of the fins 42 and the copper tube 43 in summer.

[0053] Furthermore, when the pure water on the surface of the composite mesh fabric 56 is constantly filtered and intercepted by the external airflow, the moisture on the surface of the composite mesh fabric 56 gradually evaporates and dries out, and the water level of the pure water in the water storage tank 5 gradually decreases, making it difficult to continuously soak the composite mesh fabric 56, making it difficult to maintain a uniform humidity on the surface of the composite mesh fabric 56.

[0054] At this time, the controller can be used to start the cylinder 31 and push it out, so that the pressure of the pressure rod 32 on the protective frame 41 is reduced, and the contact position between the pressure rod 32 and the protective frame 41 is changed, so that the protective frame 41 can be flipped toward the mounting bracket 3 under the reset and retraction action of the first spring 33.

[0055] During the flipping process, the protective frame 41 can pull the pull rope 54, which in turn pulls the pull rod 53 and the rubber plate 52. This causes the rubber plate 52 to press down the pure water in the water storage tank 5, raising the water level in the tank. This achieves the purpose of repeatedly soaking the composite mesh fabric 56, keeping it in a uniformly moist state. This improves the efficiency of the composite mesh fabric 56 in intercepting and initially cooling the outside air, thereby enhancing the stability of the motor 25 and fan blades 26 in efficiently dissipating heat from the fins 42 and copper tubes 43.

[0056] It should be noted that, according to the instruction manual attached... Figure 8 As shown, the water inlet on the surface of the cross frame 102 is located in the middle of both sides of the cross frame 102 and is sealed by a rubber plug. The surface of the composite mesh 56 is made of polyester fiber dust removal mesh, and the bottom layer is made of hydrophilic modified polyester felt.

[0057] When the cylinder 31 returns to its original position, that is, when the pressure rod 32 squeezes the protective frame 41 and flips it toward the ventilation frame 111, the protective frame 41 loses its tension on the pull rope 54, which causes the rubber plate 52 to reset under the action of the second spring 51, in order to wait for the next time to raise the water level of pure water.

[0058] Example 3: Support rods 6 are fixed at both ends of the two pressure rods 32 on opposite sides, a center plate 61 is fixed at the middle of the two support rods 6 on opposite sides, and side plates 62 are fixed at both ends of the two support rods 6 on opposite sides. A linkage shaft 63 is rotatably connected inside the side plate 62, and a first auxiliary fan blade 64 is fixed at the bottom of the linkage shaft 63.

[0059] The top of the linkage shaft 63 has a polygonal groove 65, the bottom of the fan blade 26 is fixed with a linkage rod 66, the linkage rod 66 is slidably connected to the polygonal groove 65, the center plate 61 is rotatably connected with a rotating shaft 7, the bottom of the rotating shaft 7 is fixed with a second auxiliary fan blade 71, the surface of the rotating shaft 7 is connected with a belt 72, one end of the belt 72 is connected to any linkage shaft 63.

[0060] Specifically, based on Embodiment 1 and Embodiment 2, when the motor 25 starts, it can drive the fan blade 26 to rotate and perform air extraction and heat exchange operations inside the housing 11. At the same time, the fan blade 26 can drive the linkage rod 66 to rotate synchronously. Since the linkage rod 66 is slidably connected to the polygonal groove 65, when the fan blade 26 and the linkage rod 66 rotate, the linkage rod 66 drives the linkage shaft 63 to rotate synchronously, and then drives the first auxiliary fan blade 64 to rotate synchronously through the linkage shaft 63, so that the first auxiliary fan blade 64 can further perform air extraction operations inside the housing 11.

[0061] According to the instruction manual Figure 3 and 4 It can be seen that the first auxiliary fan blade 64 is located below the two protective frames 41 at opposite positions. That is, both the fan blade 26 and the first auxiliary fan blade 64 are located on opposite sides of the two protective frames 41 and are arranged vertically, so that they can respectively exhaust air above and below the protective frames 41.

[0062] Under the action of the first auxiliary fan blade 64 rotating and drawing air, the outside air enters the interior of the housing 11 through the ventilation frame 111 and flows under the protective frame 41, that is, under the fins 42 and copper tubes 43, thereby improving the overall contact between the fins 42 and copper tubes 43 and the outside air, and thus improving the heat dissipation efficiency of the fins 42 and copper tubes 43.

[0063] Furthermore, when the two linkage shafts 63 rotate, a belt 72 is connected to the surface of one of the linkage shafts 63, which in turn drives the rotating shaft 7 to rotate. The rotating shaft 7 then drives the second auxiliary fan blade 71 to rotate, and the second auxiliary fan blade 71 further ventilates the air inside the housing 11. This further changes the flow path of outside air entering the housing 11 through the ventilation frame 111, allowing outside air to more comprehensively contact the surfaces of the fins 42 and copper tubes 43, thereby improving the heat dissipation efficiency of the air cooling system of this invention.

[0064] Furthermore, when the pressure rod 32 is adjusted in height, it drives the support rod 6, the center plate 61, and the side plate 62 to adjust synchronously, thereby causing the linkage shaft 63 and the rotating shaft 7 to adjust synchronously. Since the linkage rod 66 is slidably connected to the polygonal groove 65, it ensures that the transmission of 65 and 66 does not disengage. Therefore, when the pressure rod 32 is adjusted in height, the first auxiliary fan blade 64 and the second auxiliary fan blade 71 can be adjusted in height synchronously with the pressure rod 32, thereby changing the position of the first auxiliary fan blade 64 and the second auxiliary fan blade 71 in drawing air. This further changes the airflow path inside the housing 11, further increases the contact area between the fins 42 and the copper tube 43 and the outside air, and thus improves the heat dissipation efficiency of the air cooling of the present invention.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
