Description
Technical Field
[0001] The present invention relates to the technical field of stage lights, and particularly to a heat dissipation device for stage lights with a built-in sound insulation function. Background Art
[0002] Stage and film lights are a type of lighting fixtures used in stage performances and film shootings for lighting and achieving certain lighting effects. Most stage lights have the functions of changing the beam diffusion angle, the softness of light, and color, and are equipped with special mechanisms such as focusing, iris, and color filter holders.
[0003] With the development of stage lighting technology towards high power and high brightness, the heat generation of LED light sources and drive modules has increased sharply. The heat dissipation performance directly affects the lamp life and the stability of light efficiency. Traditional stage lights need to achieve efficient heat dissipation in a closed space. At the same time, due to the sensitivity of the performance scene to noise (≤50 dB(A)), the noise control of the heat dissipation system has become a key challenge. The current mainstream heat dissipation solutions have the following defects: Forced air-cooled radiators: rely on high-speed fans (such as axial fans) to drive air flow through the heat sink, but the fan vibration and air flow turbulence cause the noise to exceed the standard (≥65 dB(A)), and the high air speed requirement exacerbates the contradiction between noise and energy consumption; Passive heat dissipation structures (such as metal fins): Although there is no fan noise, the heat dissipation efficiency is low and cannot meet the heat dissipation requirements of high-power stage lights (≥500W); Additional sound insulation devices (such as wrapping the radiator with sound insulation cotton): Although the noise can be reduced, it seriously hinders heat convection, resulting in a 30%-50% decrease in heat dissipation efficiency, and the sound insulation cotton is prone to aging and flammability at high temperatures for a long time, presenting potential safety hazards.
[0004] In the prior art, there is a structural conflict between heat dissipation and sound insulation functions: optimizing heat dissipation requires increasing the air flow speed and expanding the heat dissipation area, but this will exacerbate the air flow noise and vibration; optimizing sound insulation requires adding sound-absorbing materials or complex air ducts, but this will block the air flow path and reduce the heat dissipation efficiency. The stage lights in the prior art lack a solution for synergistic improvement of heat dissipation and sound insulation. Especially in the miniaturized design of high-power stage lights, it is difficult to balance heat dissipation efficiency and noise control, and the practicality is low. Summary of the Invention
[0005] The present invention provides a heat dissipation device for stage lights with a built-in sound insulation function, which solves the problem that the stage lights in the prior art lack a solution for synergistic improvement of heat dissipation and sound insulation. Especially in the miniaturized design of high-power stage lights, it is difficult to balance heat dissipation efficiency and noise control, and the practicality is low.
[0006] To achieve the above object, the present invention adopts the following technical solutions:
[0007] A stage light heat dissipation device with a built-in sound insulation function, including a housing embedded in the stage light. The housing includes a heat insulation housing, a heat conduction ring welded to the inner wall of the lower part of the heat insulation housing, a support cylinder welded to the outer wall of the top of the heat conduction ring, a support ring with honeycomb-shaped through holes on the outer wall, and a ventilation plate with honeycomb-shaped ventilation holes on the outer wall. A heat dissipation mechanism is arranged in the support cylinder. The heat dissipation mechanism includes an installation pipe bolted to the outer wall of the bottom of the ventilation plate and a plurality of spiral porous diversion heat dissipation plates. A temperature reduction mechanism is arranged outside the support cylinder. The temperature reduction mechanism includes a plurality of heat pipes bonded to the outer wall of the top of the heat conduction ring, a ventilation ring welded to the inner wall of the middle part of the heat insulation housing, a heat exchange ring welded to the outer wall of the bottom of the ventilation ring, and a plurality of spiral porous diversion heat dissipation fins. A blowing component is arranged at the lower part of the support cylinder. The blowing component includes a first metal rubber ring abutted against the outer wall of the top of the heat conduction ring, a first shock absorption ring bolted to the inner wall of the lower part of the support cylinder, and a blower bolted to the outer wall of the top of the first shock absorption ring. An air extraction component is arranged above the ventilation plate. The air extraction component includes a guide ring abutted against the outer wall of the top of the ventilation plate, a second metal rubber ring sleeved on the inner wall of the upper part of the heat insulation housing, a second shock absorption ring abutted against the outer wall of the top of the second metal rubber ring, and an air extractor bolted to the outer wall of the top of the second shock absorption ring. A diversion cover is arranged on the upper part of the heat insulation housing.
[0008] Preferably, the support ring is welded to the inner wall of the upper part of the support cylinder, and the ventilation plate is welded to the inner wall of the middle part of the heat insulation housing. The ventilation plate abuts against the outer wall of the top end of the support cylinder. Graphene coatings are sprayed in the honeycomb-shaped through holes of both the support ring and the ventilation plate.
[0009] Preferably, a diversion cone is welded to the bottom end of the installation pipe, and a plurality of porous diversion heat dissipation plates are respectively welded to the outer wall of the installation pipe.
[0010] Through the above scheme, the hot air flow first passes through the support ring. The honeycomb-shaped through holes on the support ring convey the hot air flow, and the graphene coating prolongs the heat contact time. Subsequently, the hot air flow moves along the porous diversion heat dissipation plates. The hot air flow collides with the inner wall of the honeycomb plate of the porous diversion heat dissipation plates to strengthen heat dissipation, and the noise energy is converted into heat energy through the composite coating. Subsequently, the air flow passes through the ventilation plate.
[0011] Preferably, a plurality of the heat pipes respectively abut against the annular outer wall of the support cylinder, and the bottom of the ventilation ring is connected to the outer walls of the tops of a plurality of the heat pipes through heat conduction gel. The inner wall of the heat exchange ring abuts against the outer walls of the upper parts of a plurality of the heat pipes. The tops of a plurality of the porous diversion heat dissipation fins abut against the outer wall of the bottom of the ventilation plate.
[0012] Through the above solution, the heat conduction ring contacts the core area of the stage light for heat dissipation, and the heat conduction ring transfers heat into the heat pipe. The coolant in the heat pipe absorbs heat and then liquefies and releases heat above the heat pipe. The ventilation plate conveys the heat above the heat pipe to a plurality of porous diversion heat dissipation fins, and the porous diversion heat dissipation fins cool the hot air flow.
[0013] Preferably, several of the porous diversion heat dissipation plates and several of the porous diversion heat dissipation fins both include an aluminum frame and a gradient pore structure honeycomb panel embedded in the aluminum frame, and a paraffin-based composite material and a ceramic fiber composite coating are sprayed inside the honeycomb panel.
[0014] Preferably, the first metal rubber ring is sleeved inside the support cylinder, and the first shock-absorbing ring abuts against the outer wall of the top of the first metal rubber ring. The hair dryer is sleeved inside the support cylinder.
[0015] Preferably, the guide ring is connected to the inner wall of the upper part of the heat insulation shell by bolts, and the second metal rubber ring abuts against the outer wall of the top of the guide ring. The second shock-absorbing ring is connected to the outer wall of the upper part of the heat insulation shell by bolts. A metal rubber strip is sleeved outside the exhaust fan.
[0016] Through the above solution, the hair dryer blows hot air above the heat insulation shell, and at the same time the exhaust fan conveys the hot air to the outside of the heat insulation shell. The first shock-absorbing ring and the first metal rubber ring cooperate with each other to shock-absorb the hair dryer, and the second shock-absorbing ring and the second metal rubber ring cooperate with each other to shock-absorb the exhaust fan, reducing the vibration generated during the operation of the hair dryer and the exhaust fan and reducing the noise generated by the vibration.
[0017] Preferably, the first metal rubber ring, the second metal rubber ring and the metal rubber strip are all formed by stamping spiral aluminum wires.
[0018] Preferably, the flow guide cover is screwed to the inner wall of the upper part of the heat insulation shell, and the second metal rubber ring is sleeved on the inner wall of the lower part of the flow guide cover. The upper part of the flow guide cover is a Coanda effect curved surface, and the inner diameter of the end of the Coanda effect curved surface gradually increases.
[0019] Through the above solution, the air flow is conveyed by the flow guide cover, and the Coanda effect is utilized to make the air flow adhere to the curved surface for flow, reducing the turbulent noise caused by air flow separation. The gradually expanding design at the end of the curved surface can partially recover the pressure and reduce the energy loss.
[0020] The beneficial effects of the present invention are as follows:
[0021] Both the porous flow - guiding heat sink plate and the porous flow - guiding heat sink fin adopt a honeycomb - shaped gradient pore structure (inlet porosity 80% → outlet 50%). While increasing the heat dissipation area (30% improvement compared to traditional fins), through the acoustic wave reflection interference and frictional loss on the inner wall of the pores, the medium - high - frequency noise is reduced by ≥15 dB(A). The spiral sound - absorbing air duct extends the air flow path by 2 - 3 times, and further attenuates the low - frequency noise (10 - 12 dB reduction in the 100 - 500 Hz frequency band) using the principle of acoustic wave phase cancellation. Moreover, the pressure loss in the air duct is reduced by 25% compared to the straight - through design, avoiding the decline of heat dissipation performance caused by the sound - absorbing structure. The first shock - absorbing ring and the first metal rubber ring cooperate with each other to shock - absorb the hair dryer, and the second shock - absorbing ring and the second metal rubber ring cooperate with each other to shock - absorb the exhaust fan, reducing the vibration generated during the operation of the hair dryer and the exhaust fan, and reducing the noise generated by the vibration. It can effectively couple heat dissipation and noise reduction and sound absorption, improve the noise reduction effect while preventing the decline of heat dissipation effect, and improve the practicability.
