Description

Technical Field

[0001] This utility model relates to the field of chiller technology, specifically a novel chiller for laser tubes. Background Technology

[0002] Laser tubes, especially CO2 laser tubes with a glass structure, are important laser sources in modern industry and scientific research. During operation, the internal gas discharge generates a large amount of heat, causing the tube temperature to rise rapidly. If the heat cannot be dissipated in a timely and even manner, it will directly lead to unstable laser output power, decreased beam quality, mode degradation, and significantly shorten the lifespan of the laser tube, and may even cause the tube to crack due to overheating.

[0003] Current technologies commonly employ water-cooling systems to dissipate heat from laser tubes. However, these systems have a series of inherent drawbacks: Glass is extremely sensitive to temperature gradients. In winter or environments with large temperature differences, if a cold laser tube is moved directly indoors and immediately subjected to high-power cooling, or if air bubbles in the cooling system cause uneven heat dissipation, enormous thermal stress will be generated inside the glass, easily leading to tube breakage. Furthermore, simple circulating cooling systems lack precise temperature feedback control, failing to dynamically adjust the cooling intensity based on the actual operating power of the laser tube and the ambient temperature. This can result in over-cooling under low loads or insufficient cooling under high loads, failing to maintain the laser tube temperature within its optimal operating range. Utility Model Content

[0004] The purpose of this invention is to provide a novel chiller for laser tubes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel chiller for laser tubes, comprising a housing, a water storage component installed on the inner side of the housing, a circulating water inlet component, a water filling component, and a circulating water outlet component respectively connected to the upper side of the water storage component, and a heat dissipation component fixedly installed on the inner side of the housing, the heat dissipation component being connected to the circulating water inlet component;

[0006] The water storage component includes a sealed tank, a circulating water pump, and a connecting pipe. The sealed tank is fixedly installed on the inner side of the casing, and the circulating water pump is fixedly connected to the bottom of the inner side of the sealed tank. The circulating water pump is connected to the circulating water outlet component by a connecting pipe.

[0007] The circulating water inlet and outlet are connected by flexible hoses. The flexible hoses are spirally arranged on the outside of the laser tube. A thermometer is installed on the outside of the sealed tank. A temperature probe is installed at the bottom of the thermometer and extends into the inside of the sealed tank.

[0008] Furthermore, the heat dissipation component includes a fan and a plate heat sink. The plate heat sink is fixedly installed on the inner side of the housing, and a fan is fixedly installed on one side of the plate heat sink. The fan is used for air cooling of the plate heat sink.

[0009] Furthermore, the circulating water inlet component includes an inlet pipe one, an inlet nozzle, an inlet pipe two, and a flow sensor. The upper side of the sealed tank is connected to the inlet pipe two, and the flow sensor is installed on the inlet pipe two. The other end of the inlet pipe two is connected to the plate radiator. The plate radiator is also connected to the inlet pipe one, and the inlet pipe one is connected to the inlet nozzle.

[0010] Furthermore, the water filling component includes a water pump, a water pipe, and a water nozzle. The upper side of the sealed tank is connected to the water pipe, the water pump is installed on the water pipe, and the other end of the water pipe is connected to the water nozzle.

[0011] Furthermore, the circulating water outlet component includes a water outlet pipe and a water outlet nozzle. The upper side of the sealed tank is connected to the water outlet pipe, and the other end of the water outlet pipe is connected to the water outlet nozzle.

[0012] The circulating water pump is fixedly installed at the bottom inside the sealed tank, providing the circulation power. The circulating water pump draws cooling water from the sealed tank through a connecting pipe, pumps it into the outlet pipe of the circulating water outlet component, and finally outputs it through the outlet nozzle;

[0013] The flexible hose connecting to the water outlet is tightly wound in a spiral pattern around the outer wall of the laser tube. This design increases the heat exchange area, allowing the cooling water to efficiently and evenly absorb the heat generated by the laser tube during operation, thus becoming "hot water" carrying heat.

[0014] Furthermore, a temperature controller is fixedly installed on the inner side of the housing, and the temperature controller is electrically connected to the circulating water pump.

[0015] After absorbing heat, the "hot water" returns to the chiller through another hose, via the inlet nozzle and inlet pipe of the circulating water inlet.

[0016] The returned "hot water" first enters the plate radiator of the heat sink. Simultaneously, a fan installed on one side of the radiator starts, forcing ambient air through the radiator fins, quickly carrying away heat and expelling it outside the machine (through ventilation slots), thus lowering the water temperature to near ambient temperature. After heat dissipation is complete, the cooling water flows back to the sealed tank through the inlet pipe, ready to begin the next cycle.

[0017] Furthermore, the housing is provided with an observation slot corresponding to the thermometer, and the housing is also provided with a ventilation slot corresponding to the fan.

[0018] The thermometer probe extends directly into the sealed tank to monitor the core temperature of the circulating cooling water in real time. The temperature controller communicates with the thermometer to receive temperature signals.

[0019] The thermostat is electrically connected to the circulating water pump. When the laser tube power changes or the ambient temperature fluctuates, causing the water temperature to deviate from the set range, the thermostat can dynamically adjust the operating status of the water pump or adjust the system's heat dissipation capacity through other actuators (such as controlling the fan speed) to ensure a constant output water temperature and effectively avoid thermal shock.

[0020] Compared with the prior art, this utility model provides a novel chiller for laser tubes, which has the following beneficial effects:

[0021] This invention utilizes a closed-loop control system comprised of a thermometer and a temperature controller to monitor and dynamically adjust the cooling system's heat dissipation capacity in real time. This ensures the laser tube always operates within a constant, optimal temperature range, effectively preventing the risk of glass tube shattering due to sudden temperature changes. Furthermore, it integrates all functional modules—water storage, circulation, heat dissipation, temperature control, and water replenishment—into a single, compact housing, achieving "plug and play" functionality and simplifying installation and maintenance. More importantly, the system incorporates a flow sensor in the circulating water path, forming a safety interlock with the laser power supply. The laser tube is only allowed to start after confirming normal cooling water flow, fundamentally eliminating the risk of instantaneous laser tube burnout due to forgetting to turn on the chiller or water path blockage, providing crucial safety assurance.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] Please see Figures 1-5 A novel chiller for laser tubes includes a housing 1, a water storage component 6 installed on the inner side of the housing 1, a circulating water inlet component 3, a water filling component 4, and a circulating water outlet component 5 respectively connected to the upper side of the water storage component 6, and a heat dissipation component 2 fixedly installed on the inner side of the housing 1, which is connected to the circulating water inlet component 3.

[0031] The water storage component 6 includes a sealed tank 61, a circulating water pump 62, and a connecting pipe 63. The sealed tank 61 is fixedly installed inside the casing 1. The circulating water pump 62 is fixedly connected to the bottom inside the sealed tank 61. The circulating water pump 62 is connected to the circulating water outlet component 5 by a connecting pipe 63.

[0032] The circulating water inlet 3 and the water outlet 52 are connected by flexible hoses. The flexible hoses are spirally arranged on the outside of the laser tube. A thermometer 7 is installed on the outside of the sealed tank 61. A temperature probe is installed at the bottom of the thermometer 7 and extends into the inside of the sealed tank 61.

[0033] Furthermore, the heat sink 2 includes a fan 21 and a plate heat sink 22. The plate heat sink 22 is fixedly installed on the inner side of the casing 1, and the fan 21 is fixedly installed on one side of the plate heat sink 22. The fan 21 is used for air cooling of the plate heat sink 22.

[0034] Furthermore, the circulating water inlet component 3 includes an inlet pipe 31, an inlet nozzle 32, an inlet pipe 33, and a flow sensor 34. The upper side of the sealed tank 61 is connected to the inlet pipe 33, and the flow sensor 34 is installed on the inlet pipe 33. The other end of the inlet pipe 33 is connected to the plate radiator 22. The plate radiator 22 is also connected to the inlet pipe 31, and the inlet pipe 31 is connected to the inlet nozzle 32.

[0035] Furthermore, the water filling component 4 includes a water pump 41, a water pipe 42, and a water nozzle 43. The upper side of the sealed tank 61 is connected to the water pipe 42, the water pump 41 is installed on the water pipe 42, and the other end of the water pipe 42 is connected to the water nozzle 43.

[0036] Furthermore, the circulating water outlet component 5 includes a water outlet pipe 51 and a water outlet nozzle 52. The upper side of the sealed tank 61 is connected to the water outlet pipe 51, and the other end of the water outlet pipe 51 is connected to the water outlet nozzle 52.

[0037] The circulating water pump 62 is fixedly installed at the bottom inside the sealed tank 61, providing the circulation power. The circulating water pump 62 draws cooling water from the sealed tank 61 through the connecting pipe 63, pumps it into the outlet pipe 51 of the circulating water outlet 5, and finally outputs it through the outlet nozzle 52;

[0038] The flexible hose connecting to the water outlet 52 is tightly wound in a spiral pattern around the outer wall of the laser tube. This design increases the heat exchange area, enabling the cooling water to efficiently and evenly absorb the heat generated during laser tube operation, thus becoming "hot water" carrying heat.

[0039] Furthermore, a thermostat 8 is fixedly installed on the inner side of the housing 1, and the thermostat 8 is electrically connected to the circulating water pump 62.

[0040] After absorbing heat, the "hot water" returns to the chiller through another hose, via the inlet 32 ​​and inlet pipe 31 of the circulating water inlet component 3.

[0041] The returned "hot water" first enters the plate radiator 22 of the heat sink 2. At the same time, the fan 21 installed on one side of the radiator starts, driving ambient air to flow through the radiator fins, quickly carrying away the heat and expelling it outside the machine (through the ventilation slot 10), thereby reducing the water temperature to close to the ambient temperature. After heat dissipation is completed, the cooling water flows back to the sealed tank 61 through the inlet pipe 33, ready to start the next cycle.

[0042] Furthermore, the housing 1 is provided with an observation slot 9 corresponding to the thermometer 7, and the housing 1 is also provided with a ventilation slot 10 corresponding to the fan 21.

[0043] The probe of thermometer 7 extends directly into the sealed tank 61 to monitor the core temperature of the circulating cooling water in real time. Since the temperature controller 8 is connected to thermometer 7, it receives temperature signals.

[0044] The thermostat 8 is electrically connected to the circulating water pump 62. When the laser tube power changes or the ambient temperature fluctuates, causing the water temperature to deviate from the set range, the thermostat can dynamically adjust the operating status of the water pump or adjust the system's heat dissipation capacity through other actuators (such as controlling the speed of the fan 21) to ensure a constant output water temperature and effectively avoid thermal shock.

[0045] The specific usage and function of this embodiment are as follows:

[0046] The system's heat storage and circulation center is the water storage unit 6, the core of which is a sealed tank 61. The tank stores the cooling medium (using purified water).

[0047] The circulating water pump 62 is fixedly installed inside the bottom of the sealed tank 61, providing the circulation power. The circulating water pump 62 draws cooling water from the sealed tank 61 through the connecting pipe 63, pumps it into the outlet pipe 51 of the circulating water outlet 5, and finally outputs it through the outlet nozzle 52.

[0048] The flexible hose connecting to the water outlet 52 is tightly wound around the outer wall of the laser tube in a spiral manner. This design increases the heat exchange area, enabling the cooling water to efficiently and evenly absorb the heat generated when the laser tube is working, thus becoming "hot water" carrying heat.

[0049] After absorbing heat, the "hot water" returns to the chiller through another hose, via the inlet 32 ​​and inlet pipe 31 of the circulating water inlet component 3.

[0050] The returned "hot water" first enters the plate radiator 22 of the heat sink 2. At the same time, the fan 21 installed on one side of the radiator starts, driving ambient air to flow through the radiator fins, quickly carrying away the heat and expelling it outside the machine (through the ventilation slot 10), thereby reducing the water temperature to close to the ambient temperature. After heat dissipation is completed, the cooling water flows back to the sealed tank 61 through the inlet pipe 33, ready to start the next cycle.

[0051] To achieve precise control of the cooling temperature, the system is equipped with a closed-loop control system consisting of a thermometer 7 and a temperature controller 8. The probe of the thermometer 7 extends directly into the sealed tank 61 to monitor the core temperature of the circulating cooling water in real time. The temperature controller 8 is communicatively connected to the thermometer 7 and receives temperature signals.

[0052] The thermostat 8 is electrically connected to the circulating water pump 62. When the laser tube power changes or the ambient temperature fluctuates, causing the water temperature to deviate from the set range, the thermostat can dynamically adjust the operating status of the water pump or adjust the system's heat dissipation capacity through other actuators (such as controlling the speed of the fan 21) to ensure a constant output water temperature and effectively avoid thermal shock.

[0053] During system operation, the "low inlet, high outlet" water path principle is strictly followed: cooling water enters the laser tube from the outlet 52 located at the lower position and flows out from the inlet 32 ​​located at the higher position. This design utilizes the physical property of air bubbles naturally rising upwards, which can effectively and completely expel air from the cooling circuit, ensuring that the cooling jacket of the laser tube is filled with coolant and there are no air bubbles remaining.

[0054] The independent water filling component 4 (consisting of a water inlet 43, a water inlet pipe 42, and a water pump 41) facilitates the user to add purified water to the sealed tank 61.

[0055] All components are integrated within the housing 1, resulting in a compact structure. The observation slot 9 facilitates user observation of the thermometer 7 readings. The entire system provides a plug-and-play, safe, and reliable integrated cooling solution for the laser tube, and through optimized heat dissipation ducts and insulation design, ensures long-term stable operation of the equipment.

[0056] Meanwhile, a flow sensor 34 is installed in the circulating water circuit. The laser tube can only be turned on when the flow sensor 34 detects water flow in the circulating water circuit.

[0057] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
