Description

Technical Field

[0001] The utility model relates to the technical field of stage lamp equipment, in particular to an immersion-type high-efficiency heat dissipation stage lamp. Background Art

[0002] Stage lights are important equipment for stage performances. They can produce specific light spots on the stage and form various light effects to create an atmosphere. They are needed for various major performances, such as the Spring Festival Gala, concerts, and the opening ceremonies of various summits. In order to achieve the beauty of light and color that people pursue, the power of stage lights for these large-scale performances has also increased significantly. In order to ensure the safe use, stability and reliability of stage lights, higher requirements are put forward for the heat dissipation of stage light switch power supplies. The heat dissipation method of traditional stage light switch power supplies usually adopts air cooling. However, as the power of stage lights continues to increase, the heat generated by the switch power supply also increases. The use of fans (machines) to blow can no longer fully meet its needs, which will bring greater noise and have a greater impact on the audience's perception. In addition, if the heat dissipation requirements are not met, it is very likely that the temperature of the switch power supply will be too high, resulting in "electron migration" phenomenon, shortening its life, and even causing direct damage to the internal circuit. Therefore, more effective and quieter heat dissipation technology is needed to ensure the heat dissipation of high-power switch power supplies for stage lights. Utility Model Content

[0034] Embodiment 1

[0035] like Figures 1 to 3 as well as Figure 6 and Figure 7As shown, an immersion-type high-efficiency heat dissipation stage lamp of this embodiment has a structure including a bottom chassis 100, a support arm 101 is pivotally connected to the bottom chassis 100, a lamp head 102 is pivotally connected to the support arm 101, a switching power supply 200 is also installed inside the bottom chassis 100, and the switching power supply 200 may include a ballast. When the stage lamp is a bubble lamp, it needs to be used in conjunction with the ballast. The switching power supply 200 includes a heat dissipation installation box 1, a cooling module 3 and a circulating heat absorption tube 4. The electronic components 201 of the stage light switching power supply 200 are installed inside the heat dissipation installation box 1. At the same time, a dielectric coolant 2 is stored inside the heat dissipation installation box 1, and the dielectric coolant 2 is immersed in the electronic components 201 of the stage light switching power supply to absorb the working heat of the electronic components 201 through the dielectric coolant 2. The dielectric coolant 2 needs to have high insulation, low viscosity, and non-flammable properties, and has a low boiling point and is easy to absorb heat and undergo boiling phase change, so as to absorb the heat generated by the switching power supply. Therefore, the dielectric coolant 2 of this embodiment is preferably a fluorinated liquid belonging to a fluorocarbon compound, and can also be mineral oil, silicone oil, natural ester or phenol aniline. The cooling module 3 is located outside the heat dissipation installation box 1, and a circulating refrigerant is injected into the circulating heat absorption tube 4. The refrigerant in the circulating heat absorption tube 4 absorbs the heat of the dielectric coolant 2 and transfers the heat to the cooling module 3.

[0036] It can be understood that in this embodiment, the electronic components of the stage light switch power supply are centrally installed inside the heat dissipation installation box 1 storing the dielectric coolant 2, so that the dielectric coolant 2 is immersed in the electronic components 201 of the stage light switch power supply. When the stage light is working, the heat generated by its switch power supply can be absorbed by the dielectric coolant 2, and then the heat absorbed by the dielectric coolant 2 is transferred to the cooling module 3 located outside the heat dissipation installation box 1 through the refrigerant circulating in the circulating heat absorption tube 4. In this way, the temperature of the electronic components of the switch power supply can be effectively prevented from overheating, and the heat dissipation efficiency of the stage light power supply can be effectively improved, the heat dissipation requirements of the high-power power supply of the stage light can be met, and the service life of the stage light power supply can be extended. The heat-generating electronic components immersed in the dielectric coolant 2 can be in direct contact with the dielectric coolant 2 in all directions. Compared with the traditional air-cooling or water-cooling heat dissipation method, its heat dissipation efficiency is higher, the operation is reliable, the noise is lower, and it has a good mute effect.

[0037] Specifically, the circulating heat absorption tube 4 passes through the heat dissipation installation box 1 and the internal refrigerant circulates independently. The refrigerant and the dielectric coolant 2 are independent of each other and do not mix with each other, that is, the refrigerant will not directly contact the dielectric coolant 2, ensuring that the refrigerant circulates independently inside the circulating heat absorption tube 4, so that the refrigerant can smoothly bring the heat absorbed from the dielectric coolant 2 inside the heat dissipation installation box 1 out of the external cooling module 3.

[0038] Preferably, the circulating heat absorption tube 4 is formed with a plurality of continuous spiral sections 41, each of which is located inside the heat dissipation installation box 1. This structure can increase the heat exchange area between the circulating heat absorption tube 4 and the gaseous dielectric coolant 2, improve the heat exchange efficiency, easily absorb the heat carried by the gaseous dielectric coolant 2, and quickly release heat and liquefy the gaseous dielectric coolant 2 into liquid coolant, thereby accelerating the circulating heat dissipation of the switching power supply and further improving the heat dissipation efficiency.

[0039] Specifically, the cooling module 3 includes a plurality of heat dissipation fins 31 spaced side by side, and the circulating heat absorption tube 4 passes through each heat dissipation fin 31, so that the plurality of heat dissipation fins 31 can be used to contact the circulating heat absorption tube 4 to absorb the heat of the circulating heat absorption tube 4, thereby achieving a more obvious heat dissipation effect. In addition, a temperature sensor 8 is also installed on the inner wall of the heat dissipation installation box 1 to detect the internal temperature of the heat dissipation installation box 1.

[0040] Furthermore, in order to facilitate the injection of dielectric coolant 2 into the heat dissipation installation box 1, a liquid filling port 9 is provided on the top of the heat dissipation installation box 1, and the liquid filling port 9 is connected to the inner cavity of the heat dissipation installation box 1, so that the dielectric coolant can be added to the heat dissipation installation box 1 through the liquid filling port 9.

[0041] In order to facilitate the external installation of the heat dissipation installation box 1, the outer wall of the heat dissipation installation box 1 is provided with a mounting foot 10 for connecting to the internal structure of the stage light. Preferably, the mounting foot 10 is a screw fixing seat, so that the heat dissipation installation box 1 can be fixedly connected to the inside of the stage light by screws.

[0042] Embodiment 2

[0043] This embodiment is similar to the first embodiment, except that Figure 3As shown, the liquid level of the dielectric coolant 2 is lower than the circulating heat absorbing tube 4 located inside the heat dissipation installation box 1. The circulating heat absorbing tube 4 contacts the dielectric coolant 2 in a gaseous state after absorbing the heat of the electronic component 201 and vaporizing and rising in the heat dissipation installation box 1 through heat exchange, so that the dielectric coolant 2 in a gaseous state is cooled down and then liquefied and drips again. That is to say, a part of the circulating heat absorbing tube 4 contacts the cooling module 3, and a part is located inside the heat dissipation installation box 1. The position of the circulating heat absorbing tube 4 inside the heat dissipation installation box 1 is higher than the liquid level of the dielectric coolant 2, so that the circulating heat absorbing tube 4 does not directly contact the dielectric coolant 2 in a liquefied state. During the operation and heating of the switch power supply of the stage lamp, the circulating heat absorbing tube 4 contacts the dielectric coolant 2 in a gaseous state after absorbing the heat of the electronic component and vaporizing and rising in the heat dissipation installation box 1 through heat exchange, so that the dielectric coolant 2 in a gaseous state is cooled down and then liquefied and drips again. The circulating heat absorption tube 4 is higher than the liquid level of the dielectric coolant 2 inside the heat dissipation installation box 1, so that the dielectric coolant 2 can contact the circulating heat absorption tube 4 after being heated and vaporized and rising. Since the circulating heat absorption tube 4 contacts the dielectric coolant 2 that has absorbed the heat of the electronic components and vaporized and risen in a gaseous state in the heat dissipation installation box 1 through heat exchange, the gaseous dielectric coolant 2 is cooled and then liquefied and drips again. That is to say, the heat generated by the electronic components of the switching power supply of the stage light during operation is transferred to the dielectric coolant 2 in a liquid state. As the temperature gradually increases and reaches the boiling point of the dielectric coolant 2, the dielectric coolant 2 is gradually converted into a gaseous state. The gaseous dielectric coolant 2 rises and diffuses inside the heat dissipation installation box 1 and can contact the circulating heat absorption tube 4. Since the refrigerant inside the circulating heat absorption tube 4 circulates through the heat dissipation installation box 1 and the cooling module 3, the cooling module 3 can cool the refrigerant inside the circulating heat absorption tube 4, so that the refrigerant that is vaporized after absorbing heat The dielectric coolant 2 in the state can exchange heat with the refrigerant inside the circulating heat absorption tube 4 by contacting the outer wall of the circulating heat absorption tube 4, so that the dielectric coolant 2 in the gasified state can release heat and liquefy into small water droplets and drip back into the liquid dielectric coolant 2 immersed in the power electronic components, so that the power electronic components immersed in the liquid dielectric coolant 2 can be cooled. By allowing the dielectric coolant 2 to circulate and transform in a liquid-gas-liquid manner inside the heat dissipation installation box 1, the temperature balance of the stage light power supply can be dynamically maintained, and the temperature of the power electronic components can be effectively prevented from overheating. The heat dissipation efficiency of the stage light power supply can be effectively improved, the heat dissipation requirements of the high-power power supply of the stage light can be met, and the service life of the stage light power supply can be extended. The heat-generating electronic components immersed in the dielectric coolant 2 can be in direct contact with the dielectric coolant 2 in all directions. Compared with the traditional air-cooling or water-cooling heat dissipation method, its heat dissipation efficiency is higher, the operation is reliable, and the noise is lower.

[0044] The parts not mentioned in this embodiment are the same as those in the first embodiment and will not be described again here.

[0045] Embodiment 3

[0046] Combination Figure 4 and Figure 5 As shown, different from the first embodiment, both ends of the circulating heat absorption pipe 4 are respectively connected to the inside of the heat dissipation installation box 1, the refrigerant is made of the same material as the dielectric coolant 2, and the dielectric coolant 2 flows out of the heat dissipation installation box 1 into the circulating heat absorption pipe 4, and after the cooling module 3 dissipates heat, it flows back into the heat dissipation installation box 1. Optionally, two circulating heat absorption pipes 4 are provided in this embodiment, and both ends of each circulating heat absorption pipe 4 are respectively connected to the inside of the heat dissipation installation box 1, and each circulating heat absorption pipe 4 is also connected in series to the cooling module 3, so that the dielectric coolant 2 inside the heat dissipation installation box 1 can circulate through the two circulating heat absorption pipes 4 at the same time. Therefore, the dielectric coolant 2 in the heat dissipation installation box 1 can also output the heat generated by the electronic component 201 to the outside through the circulating heat absorption tube 4. The dielectric coolant 2 that has absorbed the heat can be cooled down by the cooling module 3 when passing through the cooling module 3 during the circulation flow inside the circulating heat absorption tube 4. After the cooled dielectric coolant 2 flows back into the heat dissipation installation box 1, it can cool down the heat-generating electronic component 201, thereby effectively preventing the power supply electronic component from overheating.

[0047] In addition, in order to drive the dielectric coolant 2 or refrigerant to circulate inside the circulating heat absorption tube 4, a circulating pump 6 is also installed in this embodiment. The circulating heat absorption tube 4 is connected to the circulating pump 6 to drive the refrigerant inside the circulating heat absorption tube 4 to circulate through the heat dissipation installation box 1 and the cooling module 3 through the circulating pump 6.

[0048] Preferably, the interior of the cavity of the heat dissipation installation box 1 is filled with dielectric coolant 2, so that the dielectric coolant 2 fills the inner cavity of the heat dissipation installation box 1, thereby avoiding abnormal noise caused by liquid flow collision during operation, and increasing the dielectric coolant to effectively improve the heat dissipation efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
