Description

Technical Field

[0001] This utility model relates to the field of pulsed xenon lamp technology, and in particular to a xenon lamp array cooling system. This system is especially suitable for laser inertial confinement fusion technology, and is used to solve the problem of rapid cooling and temperature monitoring after high-energy pulsed xenon lamp discharge, so as to ensure the stable operation and high efficiency of the xenon lamp array. Background Technology

[0002] Pulsed xenon lamps possess advantages over other pump sources, including high brightness, high efficiency, and long lifespan, making them crucial in laser inertial confinement fusion technology. As the pump source for laser amplifiers, the xenon lamp experiences rapid temperature rise during high-voltage triggering due to the initial formation of plasma. Without cooling, the laser's natural cooling recovery time is quite long, impacting the amplifier's performance and efficiency. Furthermore, during pulsed xenon lamp discharge, heat accumulates to varying degrees in the lamp and other components. Therefore, effectively reducing lamp temperature during operational intervals and preventing residual thermal distortion is essential. To prevent heat deposition in the lamp after high-energy discharge, cooling is necessary.

[0003] Traditional cooling methods often use compressed air to cool the lamp tube. However, compressed air may contain impurities or oil-water mixtures, which can easily contaminate the lamp tube surface, reduce its cleanliness, and even accelerate equipment aging. Furthermore, traditional methods lack real-time temperature monitoring capabilities, making it impossible to dynamically adjust the cooling intensity based on the actual temperature of the xenon lamp, resulting in energy waste or ineffective cooling.

[0004] Therefore, there is an urgent need for an efficient and reliable xenon lamp array cooling system that can effectively reduce the lamp array temperature in a short time and monitor temperature changes in real time to ensure the stable operation of the xenon lamps. Summary of the Invention

[0005] The purpose of this invention is to solve the aforementioned technical problems and provide a xenon lamp array cooling system, thereby achieving lamp array cooling and lamp array temperature monitoring.

[0006] A xenon lamp array cooling system, characterized in that it includes:

[0007] The lamp array assembly includes xenon lamps, reflectors, cover plates, and air ducts;

[0008] The cooling device includes a fan and an air duct connected to the fan, for forced air cooling of the xenon lamp;

[0009] Temperature monitoring device, including fiber optic temperature sensor, for real-time monitoring of lamp array temperature;

[0010] The control system adjusts the fan speed based on feedback signals from the fiber optic temperature sensor to achieve adaptive cooling.

[0011] The xenon lamp is installed on a fixed position in the lamp array, and both ends are fixed by buffer pads and pressure blocks.

[0012] The cover plate is fixedly connected to the reflective surface, and a high-density heat dissipation structure is provided on the side of the cover plate facing the lamp array to enhance heat exchange efficiency.

[0013] The high-density heat dissipation structure is a groove or fin design, and is made of aluminum alloy or copper alloy.

[0014] The air ducts are located on both sides of the lamp array, with their air outlets facing the surface of the xenon lamps for directional cooling.

[0015] The fan is a powerful blower, connected to the air duct via a flexible hose, and the wind speed can be automatically adjusted according to temperature changes.

[0016] The operating modes of the fan include:

[0017] The xenon lamp operates at low speed while charging.

[0018] After the xenon lamp discharges, switch to high-frequency strong wind mode;

[0019] The speed will automatically decrease after the temperature drops.

[0020] The fiber optic temperature sensor monitors the cover plate temperature non-contactly via infrared radiation and communicates with the control system.

[0021] On the other hand, this utility model also provides a method for cooling a xenon lamp array, characterized by including the following steps:

[0022] The temperature of the lamp array cover plate is monitored in real time using a fiber optic temperature sensor.

[0023] The fan speed is dynamically adjusted based on temperature data to achieve staged cooling;

[0024] Cooling airflow is directed to the surface of the xenon lamp using air guide channels;

[0025] The high-density heat dissipation structure of the cover plate accelerates heat dissipation.

[0026] Third, this utility model also provides a laser inertial confinement fusion device, characterized in that it includes the above-mentioned xenon lamp array cooling system.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1) Through optimized design of the air duct and outlet, the cooling airflow directly covers the xenon lamp surface, solving the problems of low cooling efficiency and uneven airflow distribution in traditional compressed air cooling. The fan dynamically adjusts its speed according to the xenon lamp's discharge stage (low speed during charging, strong airflow after discharge, and automatic reduction during cooling), ensuring rapid heat dissipation during high-temperature periods and energy-saving operation during low-temperature periods. The increased heat dissipation area through groove or fin design, combined with air cooling, achieves dual cooling. The system can reduce the xenon lamp temperature to a safe range within 1-2 minutes, significantly shortening the cooling interval.

[0029] 2) The fiber optic temperature sensor monitors the highest temperature point of the cover plate through infrared radiation, avoiding signal distortion caused by electromagnetic interference, and the temperature measurement accuracy reaches ±0.5℃.

[0030] 3) This utility model of xenon lamp array cooling monitoring system effectively reduces the temperature generated by the xenon lamp discharge array, has the function of temperature monitoring, and has the advantages of stable and reliable operation with short intervals and high energy.

[0033] Figure 3 Cooling schematic diagram shown Detailed Implementation

[0034] The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but this should not be construed as limiting the scope of protection of this utility model.

[0035] The xenon lamp array cooling system of this embodiment mainly includes:

[0036] The lamp array assembly includes a xenon lamp 1, a reflector 5, a cover plate 6, and an installation station 3;

[0037] Cooling system: powerful blower 11, air duct 7 and air outlet 8;

[0038] Temperature monitoring system, fiber optic temperature sensor 10 and temperature monitoring software 9.

[0039] The installation steps are as follows:

[0040] 1) Xenon Lamp 1 Fixing: Install the large-diameter pulsed xenon lamp 1 on the fixed position 3 of the lamp array. Buffer pads 2 and pressure blocks 4 are sequentially installed at both ends of the xenon lamp 1 for fixation, ensuring the xenon lamp remains stable and without displacement during high-voltage discharge. The number of xenon lamps and their connection method are based on the actual engineering application.

[0041] 2) Assembly of reflector 5 and cover plate 6: The high-reflectivity reflector 5 and cover plate 6 are fixed together. One side of cover plate 6 is provided with a high-density heat dissipation structure (such as grooves or fins) facing the inside of the lamp array. When the lamp array discharges at high voltage and high energy instantaneously, the temperature of the lamps rises rapidly. The temperature accumulated in the lamp array can be cooled by heat exchange through the high-density structure of cover plate 6. The reflector 5 is made of a high-reflectivity, radiation-resistant mirror material. The xenon lamp radiation energy can be effectively focused on the target area after being reflected by the reflector 5.

[0042] 3) Air duct connection: Install air ducts 7 on both sides of the lamp array, with the air outlets 8 aligned with the xenon lamp surface. After the xenon lamp discharges, it generates a large amount of energy, and the lamp tube temperature rises. The air outlets of the air ducts on both sides rapidly cool the lamp tube surface. The flexible hoses of air duct 7 are connected to the fan 11. The cooling fan 11 is a powerful blower, and its speed can be automatically adjusted according to experimental results. During the xenon lamp charging process, the fan blows air onto the lamp array at a certain frequency to cool it. When the xenon lamp discharges instantaneously, the lamp temperature is at its highest, and the fan accelerates the cooling of the lamp at a high frequency. As the xenon lamp temperature slowly decreases, the fan's cooling speed is automatically adjusted. By controlling the temperature change of the xenon lamp at different times through the fan speed, this cooling method effectively reduces energy consumption. The structural design of air duct 7 achieves sufficient and rapid cooling within the compact structure of the xenon lamp.

[0043] 4) Fiber Optic Temperature Sensor 10 Arrangement: The fiber optic temperature sensor 10 is aligned with the center area of ​​the cover plate 6, maintaining a certain distance to avoid electromagnetic interference, and is connected to the monitoring system via fiber optic signal. The fiber optic temperature sensor 10 uses infrared radiation to monitor the temperature change process of the lamp array cover plate. After the lamp array discharges, heat will accumulate at the cover plate, with the center of the cover plate being the hottest point. The temperature of the cover plate 6 reflects the temperature change of the lamp array. Maintaining a certain distance between the fiber optic temperature sensor 10 and the lamp array is crucial because the lamp array generates electromagnetic interference during charging and discharging. Using fiber optic communication effectively avoids the impact of interference signals on temperature acquisition.

[0044] Cooling system workflow:

[0045] 1. Initial stage (xenon lamp charging):

[0046] Fan 11 operates at low speed to provide basic cooling airflow and prevent the xenon lamp from heating up prematurely during charging.

[0047] The fiber optic temperature sensor 10 monitors the cover plate temperature in real time and feeds the data back to the control software.

[0048] 2. High-temperature stage (after xenon lamp discharge):

[0049] The xenon lamp generates a large amount of heat instantly upon discharge, causing the temperature of cover plate 6 to rise rapidly.

[0050] The monitoring software triggers the fan 11 to switch to high-frequency strong wind mode, which rapidly cools the surface of the xenon lamp through the air guide channel 7.

[0051] Reflector 5 reflects residual radiation energy to the target area, reducing heat deposition.

[0052] 3. Cooling phase (temperature drops):

[0053] As the cover plate temperature decreases, the fan speed is automatically reduced based on sensor data, entering energy-saving mode.

[0054] If the temperature does not reach the set threshold, the system will continuously monitor and dynamically adjust the wind speed until the xenon lamp returns to a safe temperature.

[0055] Through the above-described embodiments, this invention achieves intelligent cooling and precise temperature control of xenon lamp arrays, and is applicable to fields such as high-energy lasers, scientific research equipment, and industrial processing.
