Description

Technical Field

[0001] The present application relates to the field of lamp heat dissipation technology, and in particular to a distributed circulation heat dissipation structure and a waterproof stage lamp using the structure. Background Art

[0002] Lamps are mainly used for lighting, but with the development of technology and various applications, especially on stage, the combination of sound, light and electricity can show a colorful magic stage. However, due to the size of the stage performance, the power of stage lights is getting higher and higher, which causes the stage lights to emit relatively more heat during use. Therefore, only using the fins on the outside of the shell to dissipate heat cannot dissipate the heat in time, causing the operating temperature of the stage lights to be too high and malfunction.

[0003] In order to fully dissipate the heat of the stage light, a common method in the prior art is to open a heat dissipation hole in the shell of the stage light and set a heat dissipation fan at the rear to allow air to flow inside and outside the shell of the stage light, thereby dissipating the temperature of the stage light in operation in a timely manner.

[0004] However, in actual use, the use of stage lights is not limited to indoor situations. For example, in outdoor stages, such as many outdoor scenes or large stages, they need to be used outdoors. If it rains at this time, water seepage is very likely to occur. At this time, the use of stage lights can only be suspended, or the equipment can be shielded by additional temporary shielding. However, since stage lights are not always used at fixed angles, there is still the possibility of water seepage inside the stage lights. Therefore, how to optimize the heat dissipation performance of stage lights while optimizing waterproof performance is an urgent problem to be solved. Summary of the invention

[0005] In order to take into account both waterproof performance and heat dissipation performance, the present application provides a distributed circulation heat dissipation structure and a waterproof stage light using the structure.

[0006] In a first aspect, the present application provides a distributed circulation heat dissipation structure, which adopts the following technical solution:

[0007] A distributed circulation heat dissipation structure comprises a shell and a heat dissipation component, wherein a sealed chamber is formed inside the shell; a partition is arranged inside the chamber to divide the chamber into an installation chamber and a heat dissipation chamber, wherein the installation chamber is used to install a lamp, and the heat dissipation chamber is closed or connected to the outside.

[0008] The heat dissipation assembly comprises an inner heat dissipation module arranged in an installation chamber and an outer heat dissipation module arranged in the heat dissipation chamber, wherein the inner heat dissipation module is used for driving air flow in a direction toward a partition and in a direction parallel to the partition.

[0009] The outer heat dissipation module outputs a driving force for driving the air to flow toward the center of the partition, and the partition is penetrated by a plurality of heat transfer pipes connected to the inner heat dissipation module and the outer heat dissipation module.

[0010] By adopting the above technical solution, when in use, the internal heat dissipation module is arranged in the installation chamber to directly absorb the heat generated when the lamp is working and partially transfer it to the shell, and the internal heat dissipation module drives the air in the installation chamber to flow toward the partition and around the lamp to increase the heat dissipation rate when the lamp is working, and at the same time, make full use of the inner wall of the installation chamber for heat dissipation; the external heat dissipation module is arranged in the heat dissipation chamber, and drives the air to flow from the middle position of the partition toward the partition, and return from the outer circle of the heat dissipation chamber. The partition is penetrated and fixed with several heat transfer tubes arranged around the installation position of the lamp. The two ends of the heat transfer tubes are respectively connected to the inner heat dissipation module and the outer heat dissipation module, so that the heat of the air flow in the inner heat dissipation module and the installation chamber can be transferred to the outer heat dissipation module relatively quickly. At the same time, the rotating air flow will make the heat relatively fully contact with the inner wall of the heat dissipation chamber and dissipate to the outside. Compared with simple heat transfer through metal fins, the heat dissipation speed can be significantly increased. At the same time, due to the closed treatment of the chamber inside the shell, the possibility of leakage can be significantly avoided. While taking into account the heat dissipation, it can also meet the use conditions of the open-air stage when encountering rain.

[0011] Optionally, the internal heat dissipation module includes a plurality of internal fins and an internal fan arranged in the installation chamber, the internal fins are arranged around the space for installing the lamp in the installation chamber, and the heat transfer tube is passed through and fixed to the internal fins, part of the internal fan drives the air to flow toward the partition, and the remaining part of the internal fan drives the air to flow in a circular direction.

[0012] By adopting the above technical solution, the heat generated by the lamp when it is working can be directly absorbed relatively quickly through the internal fins, and in this process, the two groups of internal fans can respectively drive the air to flow toward the partition, and can also make the air flow in a circular direction, so as to reduce the possibility of interference with the lamp light, and at the same time, the air can circulate quickly, so that the heat dissipated by the lamp can be quickly dissipated to the outside and the heat transfer tube, so as to achieve the purpose of sufficient heat dissipation. Compared with static air relying only on fins, the speed of heat dissipation can be significantly increased, thereby optimizing the heat dissipation efficiency.

[0013] Optionally, the plurality of inner fins are divided into two groups arranged around the central axis of the partition, and the plurality of inner fins in the same group are arranged in an interval distribution along a direction perpendicular to the partition.

[0014] By adopting the above technical solution, the possibility of the inner fins interfering with the light of the lamp can be reduced, while the heat transferred by the lamp can be fully absorbed.

[0015] Optionally, the inner fan for driving the annular flow of air is arranged in the installation gap between two adjacent groups of inner fins.

[0016] By adopting the above technical solution, air can be driven to flow in a circular direction within a limited space.

[0017] Optionally, the external heat dissipation module includes an external fan and a plurality of external fins arranged in the heat dissipation chamber, the heat transfer pipe passes through and is fixed to the external fins, and the external fan is used to drive air to flow toward the middle position of the partition.

[0018] By adopting the above technical solution, since there is no need to consider interference with the lights, the external fan drives the air to flow toward the middle position of the partition and diffuses toward the outside under the guidance of the partition, so that the heat in the middle can be transferred to the outside in time and a stable air reflux path can be formed.

[0019] Optionally, the plurality of external fins are divided into a plurality of groups arranged around the external fan, and the external fan drives air to flow from the middle of the plurality of groups of external fins toward the partition.

[0020] By adopting the above technical solution, the heat can be fully absorbed by the external fins and stored at the same time, so as to increase the temperature difference between the inside and the outside and accelerate the speed of heat dissipation from the center of the heat dissipation air to the surrounding sides.

[0021] Optionally, the heat transfer tube is annular and has a flow path formed inside it to flow between the installation chamber and the heat dissipation chamber. The heat transfer tube is filled with a working fluid and the part located in the heat dissipation chamber is provided with a control component for driving the working fluid to flow in one direction.

[0022] By adopting the above technical solution, heat can be further quickly absorbed by the working fluid, thereby accelerating the heat transfer speed.

[0023] Optionally, the control component includes a pressure valve arranged on the heat transfer tube and a driving member for driving the flow of the working medium, the driving member includes a screw and a sleeve rotatably connected to the heat transfer tube located in the middle position of several groups of external fins and an impeller rotatably connected to the heat transfer tube, the heat transfer tube is provided with a transmission member for transmitting the impeller power to the screw, and the rotation axis of the impeller is parallel to the air flow direction in the middle position of the heat dissipation chamber.

[0024] By adopting the above technical solution, when the impeller rotates, the screw can be driven to rotate through the transmission member and the working fluid can be driven to flow toward the pressure valve. Due to the limitation of the pressure valve, the working fluid between the screw and the pressure valve will be compressed to accelerate the speed at which the working fluid heat escapes to the outside through the heat transfer tube. At the same time, when the pressure of the compressed working fluid increases to the threshold value of the pressure valve, it can be released toward the installation chamber through the pressure valve part, and can also further absorb the heat around the heat transfer tube in the installation chamber, thereby further optimizing the heat dissipation efficiency.

[0025] Optionally, the transmission member includes an outer magnetic ring and an inner magnetic ring, the magnet working surfaces of the inner magnetic ring and the outer magnetic ring are aligned and coupled, the inner magnetic ring is coaxially fixed to the screw, and the outer magnetic ring is coaxially fixed to the impeller.

[0026] By adopting the above technical solution, when the impeller rotates, the outer magnetic ring will follow the rotation. The rotating outer magnetic ring drives the inner magnetic ring to rotate through magnetic force, and drives the screw to rotate to drive the working fluid to flow. At the same time, the contactless transmission can reduce the possibility of working fluid leakage.

[0027] In a second aspect, the present application provides a waterproof stage light, which adopts the following technical solution:

[0028] A waterproof stage lamp is provided with the above-mentioned dispersed circulation heat dissipation structure.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] When in use, the internal heat dissipation module is arranged in the installation chamber to directly absorb the heat generated when the lamp is working and partially transfer it to the shell. The internal heat dissipation module drives the air in the installation chamber to flow toward the partition and around the lamp to increase the heat dissipation rate when the lamp is working. At the same time, the inner wall of the installation chamber is fully utilized for heat dissipation; the external heat dissipation module is arranged in the heat dissipation chamber, and drives the air to flow from the middle position of the partition toward the partition and return from the outer circle of the heat dissipation chamber. The partition is penetrated and fixed with several heat transfer tubes arranged around the installation position of the lamp. The two ends of the heat transfer tubes are respectively connected to the inner heat dissipation module and the outer heat dissipation module, so that the heat of the air flow in the inner heat dissipation module and the installation chamber can be transferred to the outer heat dissipation module relatively quickly. At the same time, the rotating air flow will make the heat relatively fully contact with the inner wall of the heat dissipation chamber and dissipate to the outside. Compared with simple heat transfer through metal fins, the heat dissipation speed can be significantly increased. At the same time, due to the closed treatment of the chamber inside the shell, the possibility of leakage can be significantly avoided. While taking into account the heat dissipation, it can also meet the use conditions of the open-air stage when encountering rain. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is combined with Figure 1-8 This application is described in further detail.

[0041] The embodiment of the present application discloses a distributed circulation heat dissipation structure.

[0042] Example 1

[0043] Reference Figure 2 and Figure 3The dispersed circulation heat dissipation structure includes a shell 1 and a heat dissipation component. One end of the shell 1 according to the direction of light irradiation is the head, and the other end opposite is the tail. The shell 1 is a closed structure and a partition 111 is fixedly connected inside. The partition 111 divides the inside of the shell 1 into an installation chamber 112 and a heat dissipation chamber 113. The installation chamber 112 and the heat dissipation chamber 113 are distributed along the direction from the head to the tail of the shell 1. Among them, the installation chamber 112 is used to install lamps, and the heat dissipation chamber 113 is a closed setting or a setting connected to the outside. In this embodiment 1, the heat dissipation chamber 113 is provided with a heat dissipation hole connected to the outside.

[0044] A heat dissipation component is arranged inside the shell 1, and the heat dissipation component includes an inner heat dissipation module 2 and an outer heat dissipation module 3. The inner heat dissipation module 2 is arranged in the installation chamber 112 to directly absorb the heat of the lamp when it is working, and partially transfer it to the shell 1, and the inner heat dissipation module 2 drives the air in the installation chamber 112 to flow toward the partition 111 and around the lamp to increase the heat dissipation rate when the lamp is working, and at the same time, make full use of the inner wall of the installation chamber 112 for heat dissipation.

[0045] The outer heat dissipation module 3 is arranged in the heat dissipation chamber 113, and drives the air to flow from the middle position of the partition 111 toward the partition 111, and then flows back from the outer circle of the heat dissipation chamber 113. The partition 111 is penetrated and fixed with a plurality of heat transfer tubes 12 arranged around the installation position of the lamp. The two ends of the heat transfer tubes 12 are respectively connected to the inner heat dissipation module 2 and the outer heat dissipation module 3, so that the heat of the air flowing in the inner heat dissipation module 2 and the installation chamber 112 can be transferred to the outer heat dissipation module 3 relatively quickly. At the same time, the rotating air will make the heat relatively fully contact with the inner wall of the heat dissipation chamber 113 and dissipate to the outside. Compared with the simple heat transfer through the metal fins, the heat dissipation speed can be significantly increased. At the same time, due to the closed treatment of the chamber inside the shell 1, the possibility of leakage causing lamp failure can be significantly avoided, so that while taking into account the heat dissipation, it can also meet the use conditions of the open-air stage when it encounters rain.

[0046] Reference Figure 3 and Figure 4 Specifically, the internal heat dissipation module 2 includes a plurality of internal fins 21 and an internal fan 22. The plurality of internal fins 21 are divided into a plurality of groups and the plurality of groups of internal fins 21 are arranged around the lamp installation space so as to be able to directly and timely conduct the heat generated by the lamp. In the present embodiment 1, the internal fins 21 are divided into two groups as an example for explanation. The two groups of internal fins 21 are symmetrically arranged in the installation chamber 112, and the internal fins 21 are perpendicular to the distribution direction of the head and the tail of the housing 1. The internal fins 21 of the same group are arranged at intervals along the direction perpendicular to the partition 111 and fixed by the heat transfer pipe 12.

[0047] Two relatively distributed installation gaps are formed between the ends of two adjacent groups of inner fins 21, and the inner fans 22 are divided into two groups, one of which is evenly distributed at the end positions of a plurality of inner fins 21 facing the head of the housing 1 and fixed to the installation chamber 112 through the bracket 211, so as to drive the air to flow toward the inner fins 21 in a direction perpendicular to the partition 111. The other group of inner fans 22 is partially installed in one of the installation gaps, and the other part is installed in the other installation gap, and the inner fans 22 in the installation gaps are used to drive the air to flow in the gaps toward the inner fins 21, and at the same time, reduce the impact on the light of the lamp.

[0048] When in use, the heat absorbed by the inner fins 21 and the heat absorbed by the lamp in contact with the air can be transferred relatively quickly through the air flow toward the space in the installation chamber 112 away from the lamp position and the part of the inner fins 21 away from the lamp, so as to achieve the purpose of rapid heat dissipation. At the same time, the inner wall of the installation chamber 112 is fully utilized for heat dissipation, and not only the part of the heat transfer tube 12 that contacts the inner fins 21 can serve the purpose of heat absorption and heat transfer, but other parts of the heat transfer tube 12 located in the installation chamber 112 can also serve the purpose of heat absorption and heat transfer, so that the heat can be quickly transferred to the heat dissipation chamber 113 through the heat transfer tube 12 and the partition 111, and through the flow of air, the heat absorbed by the external heat dissipation module 3 can be quickly and evenly distributed to the inside of the heat dissipation chamber 113 through the air flow in the heat dissipation chamber 113, and fully dissipated to the outside through the inner wall of the heat dissipation chamber 113. In addition, due to the separation of the partition 111 and the loss during the heat transfer process, there will be a certain temperature difference between the installation chamber 112 and the heat dissipation chamber 113, which can also promote the heat transfer speed and optimize the heat dissipation sales. At the same time, it can also expand the temperature difference between the inside and outside of the shell 1 in rainy weather which is not conducive to use, and further optimize the heat dissipation effect.

[0049] Of course, in other embodiments, the internal heat dissipation module 2 can also be configured as a plurality of internal fans 22 arranged on the inner wall of the installation chamber 112 and internal fins 21 that are staggered. The output end of the internal fan 22 is fixedly connected to a manifold having two output ports, and the two outlets of the manifold are respectively arranged toward the partition 111 and annularly toward the gap of the internal fins 21, and the two outlets of the manifold are staggered.

[0050] Reference Figure 4 In addition, the external heat dissipation module 3 includes an external fan 31 and a plurality of external fins 32. The external fan 31 is fixed to the inner wall of the heat dissipation chamber 113 corresponding to the rear of the housing 1 through a frame, and the output port of the external fan 31 is toward the center of the partition 111, so as to drive the air to flow toward the center of the partition 111 and diffuse toward the outer circle of the heat dissipation chamber 113 to form a loop. The external fan 31 is preferably a fan driven by a waterproof motor.

[0051] At the same time, the outer fins 32 are parallel to the partition 111, and the plurality of outer fins 32 are divided into two groups and the two groups of outer fins 32 are arranged around the external fan 31, and a space for direct air flow is reserved between the two groups of outer fins 32, so that the heat introduced into the heat dissipation chamber 113 by the heat transfer tube 12 through the external fan 31 and the heat absorbed by the partition 111 can be quickly dispersed and transferred to the inner wall of the heat dissipation chamber 113 through the rotating flow of air for heat dissipation treatment, so as to achieve the purpose of optimizing the heat dissipation performance.

[0052] The implementation principle of Example 1 is: when in use, the heat generated by the lamp will be indirectly transferred to the inner fins 21 through the air or directly transferred to the inner fins 21 through contact. At the same time, at this time, the internal fan 22 flows through the rotation in the installation chamber 112, so that the heat absorbed by the inner fins 21 and the heat directly dissipated to the air can be transferred to the inner wall of the installation chamber 112 relatively quickly, and dissipated to the outside through the inner wall of the installation chamber 112, thereby optimizing the heat dissipation utilization rate of the outer wall of the shell 1.

[0053] At the same time, the heat transfer tube 12 can also fully absorb the heat in the inner fins 21 and the air through the part located in the installation chamber 112 and transfer it to the heat dissipation chamber 113. At this time, the outer fins 32 cooperate with the flow of the rotating air to quickly and fully transfer the heat to the inner wall of the heat dissipation chamber 113, and fully utilize the heat dissipation of the outer wall of the shell 1 while maintaining a sealed state. In addition, due to the loss of heat transfer, a relatively large temperature difference will occur between the heat dissipation chamber 113 and the installation chamber 112, which can further increase the heat dissipation rate in the installation chamber 112, thereby achieving the purpose of optimizing the operating temperature around the lamp.

[0054] Example 2

[0055] Reference Figure 5 and Figure 6 , the difference between this embodiment and embodiment 1 is that the heat transfer tube 12 is annular and is arranged to avoid the projection path of the head of the shell 1, and the part of the heat transfer tube 12 located between the two groups of external fins 32 is recessed toward the partition 111 and is formed with a mounting portion 121 perpendicular to the partition 111. In addition, in order to reduce the situation where too many mounting portions 121 are crowded with each other and cause poor air circulation, a number of heat transfer tubes 12 are divided into three groups, and the mounting portions 121 formed by bending the heat transfer tubes 12 in the same group are combined and formed, that is, the heat transfer tubes 12 in the same group are located at the ends of the heat dissipation chamber 113 and are connected to the same mounting portion 121, so that the heat transfer tubes 12 in the same group can form a single channel in the middle of the heat dissipation chamber 113. Of course, in other embodiments, a single heat transfer tube 12 can also be bent to form a mounting portion 121 and form an independent channel. Among them, the heat transfer tube 12 is filled with a working medium for absorbing heat, and the working medium can be set to ammonia, carbon dioxide gas, etc., preferably ammonia.

[0056] Reference Figure 6 and Figure 7 At the same time, in order to increase the heat dissipation efficiency of the heat transfer tube 12 , the heat transfer tube 12 is provided with a control component 4 for driving the working medium to flow in a unidirectional rotation in the heat transfer tube 12 .

[0057] A connecting pipe 122 is provided in the installation chamber 112. The connecting pipe 122 has an annular structure and is fixedly connected to the end of the heat transfer tube 12 located in the installation chamber 112. The light can pass through the middle part of the connecting pipe 122, so that the working fluid can flow to dissipate heat.

[0058] Reference Figure 7 and Figure 8 Specifically, the control component 4 includes a pressure valve 41 and a driving member 42. The pressure valve 41 is installed on one of the mounting portions 121 of the heat transfer tube 12, that is, the pressure valve 41 is arranged one-to-one corresponding to the heat transfer tubes 12 of the same group. The pressure valve 41 is installed on one of the mounting portions 121 formed by the heat transfer tubes 12 of the same group to limit the flow of the working medium.

[0059] The driving member 42 is arranged at the other mounting portion 121 of the two mounting portions 121 formed by the same group of heat transfer tubes 12, and is used to drive the working fluid to flow toward the pressure valve 41. Since the pressure valve 41 will restrict the flow of the working fluid, the working fluid that evaporates after absorbing heat will be compressed, so as to significantly increase the heat release rate of the working fluid. After reaching a certain pressure, the working fluid will be quickly released by the pressure valve 41, and the compressed working fluid will flow into the portion of the heat transfer tube 12 located in the mounting chamber 112 during the release process, and can accelerate the speed of absorbing heat, so as to achieve the purpose of optimizing the efficiency of absorbing heat in the mounting chamber 112 and releasing heat in the heat dissipation chamber 113.

[0060] Specifically, the driving member 42 includes a screw 421 and an impeller 422. The screw 421 is rotatably connected to the inner wall of the mounting portion 121 through a bearing and a rod frame. The screw 421 is coaxially arranged with the mounting portion 121, and the mounting portion 121 where the screw 421 is located is arranged opposite to the mounting portion 121 where the pressure valve 41 is located. The impeller 422 is externally mounted and rotatably connected to the mounting portion 121 where the screw 421 is located, and the rotation axis of the impeller 422 is parallel to the air flow direction in the middle of the heat dissipation chamber 113, so that the impeller 422 can be driven to rotate by the flowing air when the external fan 31 is working.

[0061] At the same time, the portion of the heat transfer tube 12 where the screw 421 is provided is provided with a transmission member 43 for transmitting the power of the impeller 422 to the screw 421. The transmission member 43 includes an outer magnetic ring 431 and an inner magnetic ring 432, the magnet working surfaces of the inner magnetic ring 432 and the outer magnetic ring 431 are aligned and coupled, the inner magnetic ring 432 is coaxially fixed to the screw 421, and the outer magnetic ring 431 is coaxially fixed to the impeller 422, so that the inner magnetic ring 432 can be driven to rotate when the impeller 422 rotates. That is, a plurality of circumferentially distributed magnets are embedded on the inner magnetic ring 432 and the outer magnetic ring 431, and the working surfaces of the magnets on the inner magnetic ring 432 and the outer magnetic ring 431 are aligned, so that the magnets of the inner magnetic ring 432 can be coupled to the magnets of the outer magnetic ring 431, so that when the outer magnetic ring 431 rotates with the impeller 422, it can drive the inner magnetic ring 432 to rotate, so as to drive the screw 421 to rotate, drive the working fluid to flow toward the pressure valve 41 and compress the working fluid. Of course, in other embodiments, the driving member 42 can also be driven by gear transmission, or directly drive the screw 421 to rotate by a motor.

[0062] The implementation principle of Example 2 is as follows: when in use, the heat transfer tube 12 located in the installation chamber 112 will absorb heat and increase the temperature of the working fluid, or even evaporate. At this time, the external fan 31 will drive the impeller 422 to rotate and drive the outer magnetic ring 431 to rotate. The outer magnetic ring 431 drives the inner magnetic ring 432 to rotate through magnetic force, thereby causing the screw 421 to rotate. On the one hand, the working fluid in the installation chamber 112 of the heat transfer tube 12 can be extracted and driven to flow toward the pressure valve 41. Due to the restriction of the pressure valve 41, the working fluid will be compressed, thereby increasing the heat release rate of the working fluid in the heat dissipation chamber 113. When the pressure increases to the threshold of the pressure valve 41, the working fluid will be released toward the installation chamber 112. During the release process, the heat transfer tube 12 fully absorbs the heat in the air in the installation chamber 112 and the heat of the inner fins 21, thereby optimizing the heat dissipation efficiency while reducing the possibility of external leakage.

Figure 1 The stage lamp is applied with the dispersed circulation heat dissipation structure in the above-mentioned embodiment 1 or embodiment 2. The lamp is fixedly installed in the space between the two groups of inner fins 21 and fixed to the inner fins 21 through the frame.

[0065] At the same time, the head of the shell 1 is provided with an opening and a lamp lens 13 is sealed and fixed by a sealing ring for providing light illumination; at the same time, the shell 1 is provided with a plurality of inspection ports 14 corresponding to the heat dissipation chamber 113, and the inspection ports 14 are covered and fixed with a cover body 141, and the cover body 141 and the edge of the inspection port 14 are sealed by a sealing ring to facilitate maintenance.
