Description

Technical Field

[0001] The invention relates to the field of waterproof stage lamps, and in particular to the field of a heat dissipation module and a heat dissipation device. Background Art

[0002] The heat dissipation of waterproof lamps is mainly divided into heat dissipation at the light source position and heat dissipation of the air inside the lamp head. At present, stage lamps generally use fin heat sinks to dissipate heat at the light source position. This method has a relatively good heat dissipation effect on the light source position. However, for the heat dissipation of the air inside the lamp head, the air convection inside and outside the lamp head is generally used to achieve rapid heat dissipation. For stage lights with high requirements for waterproof performance, it is usually simply to set multiple fans at different positions inside the lamp head to form an internal circulation, so as to guide the heat inside the lamp head to the shell of the lamp head, and use the heat exchange between the shell and the outside world to dissipate heat, which is inefficient. Alternatively, an insulation layer is established inside the lamp head to isolate the light source component with high heat generation from other components of the lamp head, forming two relatively independent cavities in the light source area and the non-light source area, but it still cannot solve the problem of high air temperature in the non-light source area inside the lamp head, and high temperature will cause the service life of various components inside the lamp head to be seriously reduced. Summary of the invention

[0003] The purpose of the present invention is to provide a heat dissipation module and a heat dissipation device to solve the problem of low heat dissipation efficiency of internal air circulation in the lamp holder faced by current lamps, and to quickly reduce the air problem inside the lamp holder cavity.

[0004] The technical solution of the present invention is as follows: On the one hand, a heat dissipation module includes a heat dissipation plate for installing a light source assembly, a heat sink located directly below the heat dissipation plate and connected thereto, the heat sink including a middle heat sink, side heat sinks located on both sides of the middle heat sink and arranged at intervals with the middle heat sink and symmetrically arranged with each other; and also includes a hollow metal tube with openings at both ends that is embedded in the middle of the side heat sink, and the openings at both ends of the hollow metal tube are facing the light emitting direction.

[0005] Furthermore, the side radiator is a fin radiator; and the middle radiator is a radiator composed of a plurality of fins and a plurality of heat pipes.

[0006] Furthermore, the interval between the side radiator and the middle radiator is a reserved space for installing a fan of a heat dissipation fan.

[0007] Furthermore, the hollow metal tube includes a middle portion transversely embedded in the side radiator and end portions respectively extending outside the side radiator.

[0008] Furthermore, the tip of the end portion is oriented perpendicular to the heat sink.

[0009] Furthermore, it also includes a wind speed damping component, which is arranged inside the hollow metal tube and penetrates therein.

[0010] Furthermore, the wind speed damping component is provided with a plurality of wind speed damping units, and the wind speed damping units include a wind shielding portion and a plurality of air leakage holes.

[0011] On the other hand, a heat dissipation device includes a heat dissipation module as described above, and also includes a heat dissipation module fixing plate located directly above the heat dissipation module and fixed thereto, a heat dissipation fan assembly located in a fan reserved position, a light source assembly and an internal circulation boost assembly located on one side of the radiator fixing plate.

[0012] Furthermore, the radiator fixing plate is provided with ventilation holes corresponding to the openings at both ends of the hollow metal tube, wherein the ventilation holes on one side are air inlet holes, and the ventilation holes on the other side are air outlet holes.

[0013] Specifically, the internal circulation boost component includes a boost fan, a fan mounting plate and an air guide nozzle. The boost fan is fixed to the radiator fixing plate through the fan mounting plate. One end of the air guide nozzle is connected to the air outlet of the boost fan, and the other end is connected to the air inlet.

[0014] In more detail, the boost fan is a blower, and the air outlet of the blower is perpendicular to the radiator fixing plate.

[0015] Furthermore, the heat dissipation fan assembly includes a fan fixing frame and a heat dissipation fan mounted on the fan fixing frame, and the fan fixing frame is adapted to the fan reserved position.

[0016] Compared with traditional technical solutions, the advantages of this technical solution are: By directly adding a hollow metal tube with openings at both ends to the radiator and combining it with a booster fan, the internal hot air of the lamp holder can transfer the heat directly to the radiator through the metal hollow tube for heat dissipation. The heat dissipation efficiency is much higher than the conventional heat dissipation of the air inside the lamp holder by heat exchange between the shell and the outside world.

[0017] The wind speed damping member arranged in the hollow metal tube enables the hot air entering the hollow metal tube to exchange heat with the radiator for a longer time, thereby more efficiently dissipating the heat of the internal circulating hot air entering the hollow metal tube.

Implementation

[0024] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0027] On the one hand, as attached Figure 1-4 As shown, a heat dissipation module includes a heat dissipation plate 11 for mounting a light source assembly 4, a heat sink 12 located directly below the heat dissipation plate 11 and connected to the heat dissipation plate 11, and the heat sink 12 includes a middle heat sink 121, and side heat sinks 122 located on both sides of the middle heat sink 121 and arranged in parallel with the middle heat sink 121; the two side heat sinks 122 are symmetrically arranged. It also includes a hollow metal tube 13 with two ends opened and embedded in the middle of the side heat sink 122, and the two ends of the hollow metal tube 13 are opened toward the light emitting direction.

[0028] In this embodiment, there are two hollow metal tubes 13, which correspond to two side radiators 122 respectively. The beneficial effect of this embodiment is that the arrangement of the hollow metal tube 13 can enable the internal circulating hot air inside the lamp holder to transfer heat to the side radiator 122 through the hollow metal tube 13, thereby achieving heat dissipation of the internal circulating air inside the lamp holder. This heat dissipation method for the internal circulating hot air inside the lamp holder has a much higher heat dissipation efficiency than the traditional heat dissipation through the outer shell of the lamp holder. At the same time, the heat dissipation module after adding the hollow metal tube 13 and the heat dissipation module before adding the hollow metal tube 13 occupy almost the same space inside the lamp.

[0029] As one of the implementations, the side radiator 122 is a fin radiator; the middle radiator 121 is a radiator composed of a plurality of fins and a plurality of heat pipes. The effective effect of this implementation is that, through the matching arrangement of the side radiator 122 and the middle radiator 121, a mounting position for the heat dissipation fan assembly is reserved, making the overall volume smaller.

[0030] As one embodiment, the interval between the side radiator 122 and the middle radiator 121 is a fan reserved position 123 for installing a heat dissipation fan. The beneficial effect of this embodiment is that the two fan reserved positions 123 can accommodate four heat dissipation fans, which is more conducive to heat dissipation.

[0031] As one embodiment, the hollow metal tube 13 includes a middle portion 131 transversely embedded in the side radiator and end portions 132 extending outside the side radiator. The tip of the end portion 132 is oriented perpendicular to the heat sink 11. This embodiment has the beneficial effect of being easily connected to the air outlet of the booster fan 51 to form a smoother air path.

[0032] As one embodiment, a wind speed damping member 14 is further included, and the wind speed damping member 14 is arranged inside and penetrates the hollow metal tube 13. The beneficial effect of this embodiment is that, by increasing the flow speed of the hot air entering the hollow metal tube 13, more heat of the hot air is transferred to the wind speed damping member 14, thereby increasing the heat dissipation efficiency of the hot air.

[0033] like Figure 5 As shown, as one embodiment, the wind speed damping member 14 is provided with a plurality of wind speed damping units 141, and the wind speed damping unit 141 includes a wind shielding portion 1411 and a plurality of air leakage holes 1412. The beneficial effect of this embodiment is that the damping of air flow is increased and the speed of air flow is reduced.

[0034] On the other hand, a heat dissipation device includes a heat dissipation module 1 as described above, and also includes a heat dissipation module fixing plate 2 located directly above the heat dissipation module 1 and fixed to the heat dissipation module 1, a heat dissipation fan assembly 3 located at the fan reserved position 123, a light source assembly 4 and an internal circulation boost assembly 5 located on one side of the heat dissipation fixing plate 2. The beneficial effect of this embodiment is that the heat dissipation fan assembly 3 is used to assist the heat dissipation of the light source assembly 4, and the internal circulation boost assembly 5 is used to assist the internal circulation heat dissipation of the hot air inside the lamp holder. Through the heat dissipation fan assembly 3 and the internal circulation boost assembly 5, the heat dissipation device not only achieves the heat dissipation effect at the conventional light source assembly 4, but also achieves the internal circulation heat dissipation effect inside the lamp holder.

[0035] As one of the embodiments, the radiator fixing plate 2 is provided with ventilation holes corresponding to the openings at both ends of the hollow metal tube 13, wherein the ventilation holes on one side are air inlet holes 21, and the ventilation holes on the other side are air outlet holes 22. The beneficial effect of this embodiment is that, through the arrangement of the air inlet holes 21 and the air outlet holes 22, in conjunction with the internal circulation booster assembly 5, the hot air inside the lamp holder can form an air path in the hollow metal tube 13, and at the same time, the hot air inside the lamp holder can achieve internal circulation.

[0036] As one of the embodiments, the internal circulation boosting assembly 5 includes a boosting fan 51, a fan mounting plate 53 and an air guide nozzle 52. The boosting fan 51 is fixed on the radiator fixing plate 2 through the fan mounting plate 53. One end of the air guide nozzle 52 is connected to the air outlet of the boosting fan 51, and the other end is connected to the air inlet 21. The boosting fan 51 sucks the hot air inside the lamp holder and blows it out from its air outlet, thereby entering one end of the hollow metal tube 13 through the air inlet 21. After the heat is dissipated inside the hollow metal tube 13, it goes out from the other end of the hollow metal tube 13, thereby returning to the inside of the lamp holder through the air outlet 22 again, thus forming an internal circulation heat dissipation of the hot air inside the lamp holder. The specific shapes of the two ends of the air guide nozzle are adapted to the connection point, that is, the shape of one end of the air guide nozzle 52 connected to the air outlet of the boosting fan 51 is adapted to the shape of the air outlet, and the shape of the other end connected to the air inlet 21 is adapted to the air inlet 21.

[0037] In this embodiment, the hollow metal tube 13 is a circular tube, the air outlet of the booster fan 51 is rectangular, and there are two of them, which are arranged adjacent to each other. One end of the air guide nozzle 52 is rectangular, and the other end is a circular hole.

[0038] As one embodiment, the booster fan 51 is a blower, and the air outlet of the blower 51 is perpendicular to the radiator fixing plate 2. The beneficial effect of this embodiment is that it is more convenient to form an air path channel, so that the hot air inside the lamp holder can be sucked in and flows.

[0039] As one implementation manner, the heat dissipation fan assembly 3 includes a fan fixing frame 32 and a heat dissipation fan 31 installed on the fan fixing frame 32 , and the fan fixing frame 32 is adapted to the fan reserved position 123 .

[0040] In the heat dissipation device of this embodiment, the hot air inside the lamp holder is sucked in from the air inlet by the booster fan 51 in the internal circulation booster assembly 5, and then blown out from its air outlet, and enters the hollow metal tube 13 through the air guide nozzle 52 and the air inlet hole 21; because the hollow metal tube 13 is located on the side radiator 122, the heat conducted to the hollow metal tube 13 by the hot air can be quickly conducted to the side radiator 122 and released to the outside, so that the hot air entering the hollow metal tube 13 can be greatly cooled when it comes out of the air outlet 22. At the same time, by adding the wind speed damper 14, the flow rate of the hot air in the hollow metal tube 13 is reduced, so that the hot air can be cooled more fully.
