Description

Technical Field

[0001] The present invention relates to the technical field of light source simulation equipment, and in particular to a heat dissipation mechanism for simulating a space ultraviolet light source. Background Art

[0002] In the field of simulating near-Earth space aging, high-pressure mercury-xenon lamps are used as light sources to simulate solar ultraviolet and other radiation. The temperature of the wick reaches over a thousand degrees, and the temperature of the external lamp ball also reaches 800°C. As the light source for simulating near-Earth space light radiation in the laboratory, the two poles of the mercury lamp need to be temperature-controlled below 200°C. The ambient temperature in the lamp room cannot be too high or the temperature is uneven, causing the mercury-xenon lamp to extinguish or even explode. The outer wall of the equipment in the laboratory operating environment cannot be too high to avoid safety accidents such as burns.

[0003] According to the publication number CN201957281U, the publication (announcement) date: 2011.08.31, a solar spectrum simulation light source is disclosed, which is composed of a base and a halogen tungsten lamp, an LED white lamp, an LED green lamp and an LED ultraviolet lamp installed on the base, wherein the LED white lamp, the LED green lamp and the LED ultraviolet lamp form an LED series lamp group. The utility model has a simple structure and a reasonable design. By organically combining the light emitted by the halogen tungsten lamp, the LED white lamp, the LED green lamp and the LED ultraviolet lamp, the mixed spectrum line thereof is closer to the solar spectrum line than the xenon lamp spectrum line, and the solar spectrum can be well simulated. Moreover, the mixed light source can be used to make a solar simulator, which is closer to practical application.

[0004] In the prior art including the above-mentioned patents, LED lamp groups are used to simulate sunlight sources, but sunlight is radiant light, which contains ultraviolet radiation light. Therefore, a high-pressure mercury-xenon lamp is used to conduct experiments and simulations, which is closer to real sunlight. However, the temperature emitted by the high-pressure mercury-xenon lamp is too high during use. The high temperature emitted during the operation of the high-pressure mercury-xenon lamp will gradually increase the temperature of the device casing, which can easily cause safety accidents such as burns. Summary of the invention

[0005] The purpose of the present invention is to provide a heat dissipation mechanism for simulating a space ultraviolet light source, so as to solve the above-mentioned problem.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a heat dissipation mechanism simulating a space ultraviolet light source, comprising an outer base frame and an inner base for setting an internal mercury lamp, wherein the inner base is arranged in the outer base frame through a supporting portion so that an isolation cavity is formed between the outer base frame and the inner base.

[0010] Preferably, it also includes a sliding seat, which is horizontally slidably arranged on the partition of the aperture plate, and the sliding seat is provided with a partially conical air guide groove. The sliding seat is driven to slide horizontally so that the air guide groove moves horizontally relative to the axis of the exhaust port.

[0011] Preferably, the sliding seat is provided with an extension portion extending to the outside of the outer base frame, and the sliding seat is provided with a connecting hole, the first end of the connecting hole is connected to the extension portion, and the second end of the connecting hole is connected to the top surface of the sliding seat located in the filter chamber.

[0012] Preferably, the sliding seat is provided with an extension portion extending to abut against the inside of the first heat dissipation channel.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] like Figure 1-6As shown, a heat dissipation mechanism simulating a space ultraviolet light source includes an outer base frame 1 and an inner base 2 provided with an internal mercury lamp 3. The inner base 2 is arranged in the outer base frame 1 through a supporting portion 25 so that an isolation cavity 91 is formed between the outer base frame 1 and the inner base 2.

[0027] Specifically, Figure 1 As shown, the inner base 2 can be arranged in the outer base frame 1 through the support portion 25 to form an isolation cavity 91 between the outer base frame 1 and the inner base 2, and the outer base frame 1 is wrapped around the outer side of the inner base 2 for protection, the mercury lamp 3 is arranged in the inner base 2, and the inner base 2 is arranged in the outer base frame 1 through the support portion 25 to form an isolation cavity 91 between the inner base 2 and the outer base frame 1, when the mercury lamp 3 is working and the temperature in the inner base 2 rises, due to the existence of the isolation cavity 91, the heat emitted by the mercury lamp 3 of the inner base 2 received by the outer base frame 1 is less, thereby avoiding the problem of the outer base frame 1 used for protection being radiated with the heat emitted by the mercury lamp 3 and causing excessive temperature, avoiding the problem of burns caused by excessive temperature on the outer base frame 1, and improving protection and safety.

[0028] In the above technical solution, the mercury lamp 3 is arranged in the inner base 2, and the inner base 2 is arranged in the outer base frame 1 through the support part 25 to form an isolation cavity 91 between the inner base 2 and the outer base frame 1. When the mercury lamp 3 is working and the temperature in the inner base 2 rises, due to the existence of the isolation cavity 91, the heat emitted by the mercury lamp 3 of the inner base 2 received by the outer base frame 1 is less, thereby avoiding the problem of the outer base frame 1 used for protection being overheated due to the heat radiation emitted by the mercury lamp 3, avoiding the problem of burns caused by the excessive temperature on the outer base frame 1, and improving protection and safety.

[0029] As another embodiment provided by the present invention, it also includes an aperture plate 4, which is arranged in the inner base 2 to be located inside the inner base 2 to form a lamp chamber cavity 21, and a partition portion 41 is provided on the aperture plate 4 to divide the other side of the inner base 2 into a filter chamber 22 and a uniform light chamber 23, and an observation portion 24 connected to the uniform light chamber 23 is provided on the inner base 2, and the observation portion 24 extends to the outside of the outer base 1 through a through groove 12 opened on the outer base 1.

[0030] Specifically, Figure 1As shown, the inner base 2 can be arranged in the outer base frame 1 through the support portion 25 so that an isolation cavity 91 is formed between the outer base frame 1 and the inner base 2, and the outer base frame 1 is wrapped around the outer side of the inner base 2 to play a protective role. The inner base 2 is arranged in the outer base frame 1 through the support portion 25 so that an isolation cavity 91 is formed between the inner base 2 and the outer base 1. The aperture plate 4 divides the inner cavity of the inner base 2 to form a lamp chamber cavity 21. The mercury lamp 3 is arranged in the lamp chamber cavity 21, and the aperture plate 4 is provided with a through groove 42 and a grid groove 43, so that the mercury lamp 3 can be located in the lamp chamber cavity 21 and irradiate the other side of the aperture plate 4 through the through groove 42 and the grid groove 43 to simulate actual solar radiation. The partition 41 arranged on the aperture plate 4 separates the other side of the inner base 2 into a filter chamber 22 and a homogenizing chamber 23, and the observation portion 24 extends to the outside of the outer base frame 1 through the through groove 12 provided on the outer base frame 1, and the aperture plate 4 is also provided with an observation hole 411, through which the inside of the filter chamber 22 can be observed after passing through the homogenizing chamber 23 through the observation portion 24 and the observation hole 411 for conducting experiments, thereby utilizing the partition 41 to separate the filter chamber 22 and the homogenizing chamber 23 to improve the light stability during actual observation, and the aperture plate 4 separates the mercury lamp 3 in the lamp chamber 21 from the actual observation position, thereby improving the temperature stability of the observation area.

[0031] As another embodiment provided by the present invention, an exhaust port 11 connected to the filter chamber 22 and the uniform light chamber 23 is provided on the outer base frame 1, a first heat dissipation channel 51 facing the aperture plate 4 is provided on the inner base 2, a second heat dissipation channel 52 connected to the uniform light chamber 23 is provided on the inner base 2, and a third heat dissipation channel 53 connected to the filter chamber 22 is provided on the inner base 2.

[0032] Specifically, Figure 1 As shown, the exhaust port 11 opened on the outer base frame 1 is connected with the filter chamber 22 and the uniform light chamber 23 of the inner base 2. When the mercury lamp 3 is working continuously, it is necessary to ventilate and dissipate heat in the lamp chamber 21 to avoid the problem of excessive temperature in the lamp chamber 21 causing damage to the mercury lamp 3. Therefore, the exhaust port 11 is used to discharge the excess high-temperature air in the inner base 2 vertically upward, thereby improving the stability of heat dissipation and internal air pressure stability.

[0033] As another embodiment provided by the present invention, a heat dissipation channel 26 communicating with the lamp chamber cavity 21 is disposed on the inner base 2 , and the heat dissipation channel 26 extends to the outside of the outer base frame 1 through the isolation chamber 91 .

[0034] Specifically, Figure 2As shown, the heat dissipation channel 26 is connected with the lamp chamber cavity 21 of the inner base 2, and the heat dissipation channel 26 extends to the outside of the outer base frame 1 through the isolation chamber 91, and the heat dissipation cold air can be filled into the lamp chamber cavity 21 through the heat dissipation channel 26, thereby achieving the heat dissipation effect on the mercury lamp 3 in the lamp chamber cavity 21, avoiding the problem of excessive temperature in the lamp chamber cavity 21 causing damage to the mercury lamp 3, and then the filled cold air enters the lamp chamber cavity 21 and is heated and rises vertically to pass through the aperture plate 4, and then enters the filter chamber 22 and the uniform light chamber 23 to cool the filter chamber 22 and the uniform light chamber 23, and finally is discharged vertically from the exhaust port 11 to complete the overall cooling of the inner base 2, improve the heat dissipation efficiency, and ensure the working stability of the mercury lamp 3.

[0035] The inner base 2 is provided with a first heat dissipation channel 51 facing the aperture plate 4, the inner base 2 is provided with a second heat dissipation channel 52 connected with the light homogenizing chamber 23, and the inner base 2 is provided with a third heat dissipation channel 53 connected with the filter chamber 22. The first heat dissipation channel 51 can dissipate heat for the aperture plate 4, while the second heat dissipation channel 52 can dissipate heat inside the filter chamber 22, and the third heat dissipation channel 53 can dissipate heat for the light homogenizing chamber 23, thereby utilizing the first heat dissipation channel 51, the second heat dissipation channel 52 and the third heat dissipation channel 53 to achieve further refined heat dissipation inside the inner base 2, thereby improving the heat dissipation efficiency and the temperature uniformity inside the inner base 2.

[0036] As another embodiment provided by the present invention, it also includes a sliding seat 6, which is horizontally slidably arranged on the partition portion 41 of the aperture plate 4, and a partially conical air guide groove 61 is opened on the sliding seat 6. The sliding seat 6 is driven to slide horizontally so that the air guide groove 61 moves horizontally relative to the axis of the exhaust port 11.

[0037] Specifically, the sliding seat 6 is provided with a sliding portion 66, and the sliding portion 66 is slidably provided in the sliding groove 412 provided on the partition 41, as shown in FIG. Figure 2As shown, the sliding seat 6 is horizontally slidably disposed on the partition 41 of the aperture plate 4 , and a partially conical air guide groove 61 is provided on the sliding seat 6 . When the sliding seat 6 is in a default state, the air guide groove 61 is aligned with the air outlet 11 . When the heat dissipation channel 26 fills heat dissipation cold air into the lamp chamber cavity 21, the heat dissipation effect of the mercury lamp 3 in the lamp chamber cavity 21 is achieved, and the problem of excessive temperature in the lamp chamber cavity 21 causing damage to the mercury lamp 3 is avoided. Secondly, the filled cold air is heated after entering the lamp chamber cavity 21 and rises vertically to pass through the aperture plate 4, and then enters the filter chamber 22 and the uniform light chamber 23 to cool the filter chamber 22 and the uniform light chamber 23. Finally, the gas temperature rises and flows upward, and then it is easy to flow along the lower end to the upper end of the air guide groove 61 of the sliding seat 6 to be vertically discharged from the exhaust port 11 to the outside of the outer base 1, thereby utilizing the air guide groove 61 of the sliding seat 6 to improve the flow and discharge of high-temperature gas in the inner base 2, further improving the thermal conductivity efficiency and improving the operating stability of the equipment.

[0038] When the mercury lamp 3 just starts to work, the temperature in the filter chamber 22 and the uniform light chamber 23 in the inner base 2 is relatively low, while the temperature in the lamp chamber 21 is relatively high, which can drive the sliding seat 6 to slide so that the air guide groove 61 moves horizontally relative to the axis of the exhaust port 11, thereby causing the air guide groove 61 to be misaligned with the exhaust port 11. At this time, the high-temperature gas is likely to stay in the filter chamber 22 and the uniform light chamber 23 for a longer time to heat up the filter chamber 22 and the uniform light chamber 23, thereby avoiding the problem of observation errors caused by excessive temperature difference between the filter chamber 22 and the uniform light chamber 23 and the lamp chamber 21, thereby improving the accuracy of the observation experiment.

[0039] As another embodiment provided by the present invention, the sliding seat 6 is provided with an extension portion 62 extending to the outside of the outer base frame 1, and a connecting hole 63 is opened on the sliding seat 6, the first end of the connecting hole 63 is connected to the extension portion 62, and the second end of the connecting hole 63 is connected to the top surface of the sliding seat 6 located in the filter chamber 22.

[0040] Specifically, Figure 4 As shown, the extension portion 62 of the sliding seat 6 extends to the outside of the outer base frame 1, and the first end of the connecting hole 63 is connected to the extension portion 62 located on the outside of the outer base frame 1, and the second end of the connecting hole 63 is connected to the top surface of the sliding seat 6 located in the filter chamber 22. When the mercury lamp 3 has been running for a long time, the heat dissipation channel 26 fills a large amount of cooling air into the lamp chamber 21. The suction cleaning component can be used to suck the first end of the connecting hole 63, and then the connecting hole 63 can be used to adsorb and remove the dust that is easily deposited on the top surface of the sliding seat 6, thereby avoiding the problem of serious heat accumulation inside the inner base 2 caused by the dust falling from the exhaust port 11 into the lamp chamber 21, and further improving the heat dissipation efficiency and working stability in the inner base 2.

[0041] As another embodiment provided by the present invention, the sliding seat 6 is provided with an extension portion 64 extending to abut against the inside of the first heat dissipation channel 51 .

[0042] Specifically, the sliding seat 6 is provided with an extension portion 64 extending to abut against the inside of the first heat dissipation channel 51. The extension portion 64 abuts against the inside of the first heat dissipation channel 51 so that the first heat dissipation channel 51 can quickly dissipate heat and cool down the sliding seat 6 body. The sliding seat 6 is slidably arranged on the partition portion 41, and direct contact heat conduction can be used to quickly dissipate heat and cool down the partition portion 41, thereby further improving the heat dissipation efficiency of the aperture plate 4.

[0043] As another embodiment provided by the present invention, an air guide hole 65 is symmetrically opened on the sliding seat 6 about the air guide groove 61, the first end of the air guide hole 65 is connected to the side wall of the air guide groove 61, and the second end of the air guide hole 65 is connected to the bottom surface of the sliding seat 6 located in the filter chamber 22.

[0044] Specifically, Figure 5 As shown, the sliding seat 6 is provided with air guide holes 65 symmetrically about the air guide groove 61, the first end of the air guide hole 65 is connected to the side wall of the air guide groove 61, and the second end of the air guide hole 65 is connected to the bottom surface of the sliding seat 6 located in the filter chamber 22. When the heat dissipation channel 26 fills the lamp chamber cavity 21 with heat dissipation cold air, the heat dissipation effect on the mercury lamp 3 in the lamp chamber cavity 21 is achieved, thereby avoiding the problem of the mercury lamp 3 being damaged due to excessive temperature in the lamp chamber cavity 21. Secondly, the filled cold air enters the lamp chamber cavity 21 and is heated and rises vertically to pass through the aperture plate 4, and then enters the filter chamber 22 and the uniform light chamber 2 3, the filter chamber 22 and the uniform light chamber 23 are cooled, and finally the temperature of the gas filled therein rises and flows upward, and then it is easy to flow along the lower end to the upper end of the air guide groove 61 of the sliding seat 6 to be vertically discharged from the exhaust port 11 to the outside of the outer base 1, and the high-temperature gas in the filter chamber 22 is also easy to flow into along the second end of the air guide hole 65 and rush out from the first end of the air guide hole 65 into the air guide groove 61, thereby further improving the flow rate of the high-temperature gas located in the air guide groove 61 to flow out of the exhaust port 11, thereby further improving the flow extraction efficiency of the high-temperature gas in the inner base 2.

[0045] As another embodiment provided by the present invention, an ellipsoidal mirror 7 for heat dissipation is arranged in the lamp chamber cavity 21.

[0046] Specifically, an ellipsoid mirror 7 for heat dissipation is provided in the lamp chamber cavity 21 , and the ellipsoid mirror 7 is used for scattering and refraction to reduce the direct heat radiation conduction heat of the mercury lamp 3 to the inner wall of the lamp chamber cavity 21 , thereby further improving the heat dissipation efficiency in the lamp chamber cavity 21 .

[0047] Working principle: The inner base 2 can be arranged in the outer base frame 1 through the support portion 25 so that an isolation cavity 91 is formed between the outer base frame 1 and the inner base 2, and the outer base frame 1 is wrapped around the outer side of the inner base 2 to play a protective role. The mercury lamp 3 is arranged in the inner base 2, and the aperture plate 4 separates the inner cavity of the inner base 2 to form a lamp chamber cavity 21. The mercury lamp 3 is arranged in the lamp chamber cavity 21, and the aperture plate 4 is provided with a through groove 42 and a grid groove 43, so that the mercury lamp 3 can be located in the lamp chamber cavity 21 through the through groove 4 2 and the grating groove 43 are used to irradiate the other side of the aperture plate 4 to simulate the actual solar radiation light. The partition 41 provided on the aperture plate 4 separates the other side of the inner base 2 into a filter chamber 22 and a homogenizing chamber 23, and the observation portion 24 extends to the outside of the outer base frame 1 through the through groove 12 provided on the outer base frame 1. The aperture plate 4 is also provided with an observation hole 411, and the inside of the filter chamber 22 can be observed through the observation portion 24 and the observation hole 411 after passing through the homogenizing chamber 23 to conduct experiments;

[0048] When the heat dissipation channel 26 fills heat dissipation cold air into the lamp chamber cavity 21, the heat dissipation effect of the mercury lamp 3 in the lamp chamber cavity 21 is achieved, and the problem of damage to the mercury lamp 3 caused by excessive temperature in the lamp chamber cavity 21 is avoided. Secondly, the filled cold air is heated after entering the lamp chamber cavity 21 and rises vertically to pass through the aperture plate 4, and then enters the filter chamber 22 and the uniform light chamber 23 to cool the filter chamber 22 and the uniform light chamber 23. Finally, the gas temperature rises and flows upward, and then it is easy to flow along the lower end to the upper end of the air guide groove 61 of the sliding seat 6 to be vertically discharged from the exhaust port 11 to the outside of the outer base frame 1, and the high-temperature gas in the filter chamber 22 is also easy to flow into along the second end of the air guide hole 65 and rush out from the first end of the air guide hole 65 into the air guide groove 61, thereby further increasing the flow rate of the high-temperature gas in the air guide groove 61 to flow out of the exhaust port 11.
