Description

TECHNICAL FIELD

[0001] The present application relates to the field of discharge tube or discharge lamp, in particular to a kind of pulse xenon lamp cooling device. BACKGROUND

[0002] Electro-optical conversion refers to the excitation and light emission phenomenon of ionized gas under the action of electric field. Among them, pulse xenon lamp is widely used as a replaceable light source in the instrument industry due to its good external spectrum, high light intensity, high light efficiency and long service life. In the process of pulse xenon lamp discharge experiment, a large amount of heat will be generated in the plasma in the pulse xenon lamp. If this heat cannot be transferred in time and efficiently, the conversion efficiency of the pulse xenon lamp will be reduced, and the long-term stable operation of the equipment will be affected. If the heat accumulation exceeds a certain limit, the xenon lamp may even burst, which will seriously endanger the personal safety of the experimenters. Therefore, a simple and efficient pulse xenon lamp cooling device is necessary to ensure the stable operation of the pulse xenon lamp and provide a reliable experimental environment for the electro-optical conversion research on pulse xenon lamp.

[0003] The traditional pulse xenon lamp cooling device is mainly a wind cooling device, and its working principle is to use a fan to drive air to flow through the surface of the lamp tube to carry away heat through convection. In low-power (such as a few watts to a few hundred watts) and non-continuous operation experimental lamps, wind cooling is a suitable choice for pulse xenon lamp cooling device due to its simplicity and economy. However, in experimental situations where the equipment space is closed or the ambient temperature is high and the pulse xenon lamp needs to be continuously operated at high power, the simple wind cooling has very limited cooling capacity, generates a lot of noise, and is prone to heat accumulation. These problems not only affect the performance of the pulse xenon lamp discharge device, increase the maintenance cost and operation complexity of the equipment, but also bring great inconvenience to the electro-optical conversion research on pulse xenon lamp. SUMMARY

[0018] Fig. 1 is a structural schematic diagram of the pulse xenon lamp cooling device according to the present application; Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. The principles and features of the present invention are described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0020] The pulsed xenon lamp mentioned in this invention is typically composed of a lamp tube and a cathode and an anode connecting the two ends of the lamp tube. The outer diameter of the cathode and anode is larger than the outer diameter of the lamp tube as a whole. The lamp tube of the pulsed xenon lamp can be, for example, a cuboid or a cylinder.

[0021] Example 1 This invention provides a pulsed xenon lamp cooling device, such as... Figures 1-3 As shown, the cooling device includes: a cooling device body 100, one end of which is provided with a xenon lamp anode placement channel 105, and the other end is provided with a xenon lamp cathode placement channel 108. The cooling device body 100 of the present invention has a symmetrical cross-section along its length, and the structure and size of both ends are the same. Therefore, the specific placement positions of the cathode and anode can be adjusted according to the adaptability during use. The end where the pulse xenon lamp anode is placed is the anode end, and the end where the cathode is placed is the cathode end. That is to say, the anode and cathode in the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108 of the present invention are only used as a distinction for understanding the specific embodiments of the present invention, and are not intended to limit either end.

[0022] The pulsed xenon lamp is inserted into the cooling device body 100 through the xenon lamp anode placement channel 105 or the xenon lamp cathode placement channel 108. The diameter of the xenon lamp anode placement channel 105 is larger than the outer diameter of the pulsed xenon lamp anode, and the diameter of the xenon lamp cathode placement channel 108 is larger than the outer diameter of the pulsed xenon lamp cathode, for example, by 0.2 to 0.5 mm, preferably 0.3 mm. This allows the pulsed xenon lamp to pass smoothly through one end of the channel into the cooling device body and then smoothly through the other end of the channel, fully accommodating the anode and cathode of the pulsed xenon lamp. After the pulsed xenon lamp is placed, the anode and cathode are respectively placed in the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108. Both ends of the pulsed xenon lamp extend a certain length from the channel opening. This extension length is sufficient to allow for subsequent fixation with external nuts and to connect to the circuit of the photoelectric conversion device. The xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108 provide support for the anode and cathode of the xenon lamp, allowing the lamp tube of the pulsed xenon lamp to be suspended in the cooling device body.

[0023] The cooling device body 100 also includes a cooling medium cavity 103, which is located between the pulsed xenon lamp and the inner wall of the cooling device body 100, and is used to introduce a first cooling medium. Since the pulsed xenon lamp is directly inserted into the cooling device body 100, the cooling medium cavity 103 can fully enclose the pulsed xenon lamp, and the cooling medium is in direct contact with the lamp tube, resulting in rapid heat transfer and thus greatly improving the cooling rate. In some embodiments of the present invention, the first cooling medium can be, for example, water, a water-based solution, or mineral oil, as long as it can absorb the heat generated by the pulsed xenon lamp and does not react with the material of the lamp tube wall. However, it should be noted that the present invention requires the use of a transparent cooling medium. Further, in some embodiments of the present invention, the cooling device body 100 is also provided with a cooling medium inlet 101 and a cooling medium outlet 102, which are connected to the cooling medium cavity 103. Both the cooling medium inlet 101 and the cooling medium outlet 102 are connected to pipes. An external storage device for the first cooling medium is provided on the cooling device. The first cooling medium is introduced from this storage device into the cooling medium chamber 103 through the cooling medium inlet 101, and then flows out from the cooling medium outlet 102. The outflowing first cooling medium can, for example, be discharged or collected for cooling before being stored back into the first cooling medium storage device and then reintroduced into the cooling medium chamber 103. Thus, this invention utilizes the first cooling medium to provide a circulating cooling path for the effective heat dissipation of the pulsed xenon lamp within the main body 100 of the cooling device.

[0024] Furthermore, in some embodiments of the present invention, solenoid valves (not shown in the figure) are provided at both the cooling medium inlet 101 and the cooling medium outlet 102. The solenoid valves can control the flow rate of the first cooling medium. In addition, the first cooling medium storage device can be equipped with a temperature control device. By controlling the temperature and flow rate of the cooling medium, the cooling temperature of the pulse xenon lamp can be controlled. For example, when the temperature of the pulse xenon lamp is high, the flow rate of the cooling medium can be increased and the temperature of the cooling medium can be reduced, thereby removing the heat generated by the xenon lamp more quickly.

[0025] Furthermore, the cooling device also includes a cooling device sleeve 200, which is installed on both sides of the cooling device body 100. The cooling device sleeve 200 has xenon lamp fastening through holes 202 at positions corresponding to the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108. Further, in some embodiments, the cooling device body 100 has threaded holes 104 at both ends, and the cooling device sleeve 200 has threaded through holes 201 at positions corresponding to the threaded holes 104. The cooling device sleeve 200 is fixed to both ends of the cooling device body 100 using external bolts and nuts. After the cooling device sleeve 200 is fitted onto the cooling device body 100, external bolts are sequentially inserted into the threaded through holes 201 on the cooling device sleeve 200 and the threaded holes 104 on the cooling device body 100, and then secured with external nuts. This securely fixes the cooling device sleeve 200 to both ends of the cooling device body 100.

[0026] Furthermore, in some embodiments of the present invention, such as Figure 1 As shown, the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108 are located at the center of the cooling device body 100. Correspondingly, the xenon lamp fastening through hole 202 is located at the center of the cooling device sleeve 200, and the outer diameters of the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108 are the same as the outer diameter of the xenon lamp fastening through hole 202. This ensures that the pulsed xenon lamp is in the center position after being placed in the cooling device body 100, and further ensures that the contact area and volume of the pulsed xenon lamp tube with the first cooling medium are the same in all directions. This ensures uniform heat dissipation and improves the service life of the pulsed xenon lamp.

[0027] Furthermore, after the pulsed xenon lamp extends into the cooling device body 100, the cathode and anode of the pulsed xenon lamp are placed in the xenon lamp cathode placement channel 108 and the xenon lamp anode placement channel 105, respectively. After installing the aforementioned cooling device retainer 200, the cathode and anode of the pulsed xenon lamp extend from the xenon lamp fastening through holes 202 at both ends of the cooling device retainer 200. In some embodiments of the present invention, the cooling device may further include an external xenon lamp fastener (not shown in the figure), which is fitted onto the pulsed xenon lamp anode and cathode passing through the xenon lamp fastening through hole to fix the pulsed xenon lamp. The size of the xenon lamp fastener is larger than the diameter of the xenon lamp fastening hole 202, and fitting it onto the cathode and anode further fixes the xenon lamp. The xenon lamp fastener can be, for example, a fastening nut. In this case, both the cathode and anode of the pulsed xenon lamp have matching threads on their outer surfaces, allowing the fastening nut to be rotated onto the cathode and anode for fixation. Alternatively, the fastener can be a sleeve that interference-fits the cathode and anode of the pulsed xenon lamp, securing the lamp by fitting it onto them. Another option is an end cap with a slot, in which the cathode and anode have protrusions that mate with the slot. Inserting the protrusions into the slot fixes the cathode and anode, thus securing the pulsed xenon lamp. Preferably, the present invention uses a fastening nut to secure the pulsed xenon lamp.

[0028] In other embodiments of the present invention, in order to improve the sealing performance of the entire cooling device, the cooling device of the present invention may further include a sealing gasket (not shown in the figure), and grooves 106 (e.g., at the entrances of the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108) are provided. Figure 2 As shown), it is used to accommodate the sealing gasket. During installation, the sealing gasket is inserted into the sealing gasket groove 106. When the xenon lamp anode and xenon lamp cathode are inserted into the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108, the xenon lamp anode and xenon lamp cathode can fit tightly with the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108, sealing the cooling medium cavity 103 and providing a sealed environment for the flow of the first cooling medium.

[0029] Similar to the sealing ring, the inner surface of the cooling device sleeve 200 may also be provided with a gasket, which has the same opening as the cooling device sleeve 200. This corresponding opening includes openings corresponding to the xenon lamp fastening through-hole 202 and the threaded through-hole 201. When installing the cooling device sleeve 200, the xenon lamp anode and cathode directly penetrate the gasket. In actual operation, the size of the gasket corresponding to the xenon lamp fastening through-hole 202 can be, for example, set to an interference fit with the outer surfaces of the xenon lamp anode and cathode, thereby ensuring tight contact at the contact points and preventing the overflow of the first cooling medium. Similarly, the gasket also has a through-hole corresponding to the threaded through-hole 201, allowing the bolt to directly penetrate the sealing gasket and enter the threaded hole 104 on the cooling device body 100 when installing the bolt.

[0030] In a preferred embodiment, the sealing gasket and liner of the present invention are both made of elastic rubber material, which can meet the sealing requirements of the present invention.

[0031] Furthermore, both the cooling device body 100 and the cooling device sleeve 200 of the present invention are made of transparent material, such as transparent acrylic, quartz, glass, etc. As mentioned above, the first cooling medium is preferably a transparent cooling medium, such as water, water-based solution or mineral oil (it needs to be a transparent fluid) to ensure light transmittance during use, thereby providing the experimental conditions required for pulsed xenon lamp spectral measurement.

[0032] In use, the cooling device of this invention first places the pulsed xenon lamp through the xenon lamp anode placement channel 105 and the xenon lamp cathode placement channel 108 into the main body 100 of the cooling device. At this time, the anode is placed in the xenon lamp anode placement channel 105, and the cathode is placed in the xenon lamp cathode placement channel 108. After installing the sealing gasket and liner, the cooling device sleeve 200 is fixed to both ends of the main body 100 of the cooling device with bolts, and the anode and cathode of the pulsed xenon lamp are fixed with xenon lamp fasteners, thereby fixing the entire pulsed xenon lamp. Thus, the entire device is fixed and assembled as a whole, and the entire pulsed xenon lamp cooling device provides a sealed environment for photoelectric conversion research experiments. Subsequently, the first cooling medium is introduced into the cooling medium cavity 103 through the cooling medium inlet 101 and the cooling medium outlet 102. The first cooling medium enters the cooling medium cavity 103 from the cooling medium inlet 101 and flows out through the cooling medium outlet 102. During this process, the flow of the first cooling medium provides effective heat dissipation for the photoelectric conversion experiment of the pulsed xenon lamp. It should be noted that when starting the photoelectric conversion experiment, the cooling medium inlet 101 and cooling medium outlet 102 should be connected to the cooling medium supply device first, and the cooling medium supply device should be turned on to pre-cool the main body 100 of the cooling device. After other experimental conditions meet the experimental requirements, the power should be turned on to carry out the photoelectric conversion experiment of the pulse xenon lamp.

[0033] The pulsed xenon lamp cooling device provided by this invention adopts an integrated sealed structure. When the pulsed xenon lamp is in operation, the internal gas generates a high-intensity arc, producing a large amount of infrared radiation heat and visible light. The cooling medium in the cooling medium chamber 103 of this invention can directly contact the pulsed xenon lamp, removing most of the waste heat from the surface and cavity of the lamp through convection and conduction. The cooling medium can circulate and cool within the cooling medium chamber 103, directly contacting the lamp tube, thus solving the problems of limited heat dissipation capacity, high noise, and easy heat accumulation in confined spaces inherent in traditional air-cooled devices. Simultaneously, the pulsed xenon lamp is fixed through the xenon lamp fastening through-hole 202, facilitating spectral acquisition. The sealing performance is improved by the cooperation of the sealing gasket and the sealing gasket groove 106. The cooling device sleeves 200 at both ends and the sealing gaskets enhance the sealing environment of the main body 100 of the cooling device, fix the position of the pulsed xenon lamp, improve experimental conditions, and ensure the stable and efficient conduct of the pulsed xenon lamp electro-optic conversion experiment.

[0034] Example 2 This embodiment provides a pulsed xenon lamp cooling device. For ease of explanation, this embodiment only describes the differences from Embodiment 1; structures identical to those in Embodiment 1 will not be repeated. The only difference between this embodiment and Embodiment 1 is that the cooling medium inlet 101 and the cooling medium outlet 102 are connected by a pipeline, and a liquid pump is installed in the pipeline. This liquid pump enables the cooling medium to form a circulating loop through the cooling medium inlet 101, the cooling medium chamber 103, the cooling medium outlet 102, and the pipeline. However, when a closed cooling medium loop is formed, as described in Embodiment 1, the cooling medium is in direct contact with the pulsed xenon lamp. Through convection and conduction, most of the waste heat from the surface of the pulsed xenon lamp and the xenon lamp chamber is carried away, causing the cooling medium temperature to rise rapidly. If a circulating loop is formed, the cooling medium returning to the cooling medium chamber will be at a high temperature, making it impossible to cool the pulsed xenon lamp.

[0035] Therefore, in this embodiment, a cooling coil 300 is also provided in the cooling medium cavity 103. For example... Figure 4 As shown, the cooling coil 300 is disposed between the pulsed xenon lamp and the cooling device body 100. In a preferred embodiment, one to four cooling coils 300 may be provided, for example, disposed above, below, to the left, or right of the pulsed xenon lamp body. Figure 4The diagram illustrates a configuration with two cooling coils 300. It should be noted that the dimensions of the cooling coils 300 must ensure that they do not obstruct observation of the pulsed xenon lamp, i.e., do not impede the experimental conditions required for pulsed xenon lamp tube-laying measurements. A second cooling medium is contained within the cooling coils 300. The specific heat capacity of the second cooling medium is lower than that of the first cooling medium. The second cooling medium, for example, can be Freon, which can effectively absorb the heat from the first cooling medium, rapidly cooling it.

[0036] In this case, as described in Example 1, the high-voltage electrically excited pulsed xenon lamp of the present invention generates a high-intensity arc light from its internal gas during operation, while simultaneously producing a large amount of infrared radiation heat and visible light. The first cooling medium in the cooling medium chamber 103 of the cooling device of the present invention can directly contact the pulsed xenon lamp, and through convection and conduction, remove most of the waste heat from the surface of the pulsed xenon lamp and the xenon lamp cavity. During this process, the temperature of the first cooling medium rises rapidly. The high-temperature first cooling medium flows through the outside of the cooling coil 300, conducting heat through the tube wall of the cooling coil 300 to the second cooling medium inside the cooling coil 300. The low-temperature first cooling medium, cooled by the second cooling medium inside the cooling coil 300, is then pumped back into the xenon lamp cooling cavity by a liquid pump, starting a new round of heat absorption cycle.

[0037] Furthermore, the second cooling medium rapidly evaporates after absorbing heat from the first cooling medium. To cool the second cooling medium and further recycle it, the main body 100 of the cooling device of this invention is also provided with a cooling coil inlet 301 and a cooling coil outlet 302. The second cooling medium enters the cooling coil 300 through the cooling coil inlet 301 and flows out through the cooling coil outlet 302. A compressor and an expansion valve are provided between the cooling coil inlet 301 and the cooling coil outlet 302. After the high-temperature and high-pressure second cooling medium enters the compressor, it releases heat to the outside through the compressor and further condenses into a medium-temperature and high-pressure liquid. Subsequently, the medium-temperature and high-pressure liquid passes through the expansion valve, causing its pressure to drop sharply, becoming a low-temperature and low-pressure liquid, which then re-enters the cooling coil 300 to cool the first cooling medium again.

[0038] Therefore, the pulsed xenon lamp cooling device provided in this embodiment can precisely control the evaporation temperature by adjusting the compressor power (frequency conversion) or the expansion valve opening, thereby precisely controlling the temperature of the first cooling medium (±1℃ or even higher precision), which is crucial for the spectral stability and lifespan of the xenon lamp. The specific heat capacity of the first cooling medium used in this embodiment is higher than that of the second cooling medium; the combination of the two can handle the heat load of the xenon lamp in the thousands or even tens of thousands of watts. Furthermore, since the cooling medium inlet does not need to be connected to an external water-cooling device, the risk of leakage caused by direct water cooling is avoided. The pulsed xenon lamp cooling device of this invention is made of transparent material, but if the temperature of the external cooling medium is too low, below room temperature, condensation may occur on the surface of the xenon lamp and the cooling device. This embodiment, through the cooperation between the first and second cooling media, can control the temperature of the first cooling medium to be higher than the ambient dew point temperature, thereby preventing condensation on the surface of the xenon lamp and the cooling device. In addition, external devices such as compressors can be installed as needed, which is beneficial for equipment integration and heat dissipation management.
