In the projection field, the light transmission efficiency is greatly enhanced due to the appearance of solid-state light sources such as laser light sources, and the projector is also developed towards more miniaturization. While the main heat generating devices in the projection apparatus are light sources, light modulators, etc.
In the prior art, the optical engine is an important component in the projection device, including a light source, an illumination lens, a reflector, a light modulator, a projection lens, an optical engine housing, and the like. The illumination light emitted by the light source reaches the light modulator through a lens and the like to form projection image light, and the projection image light is processed by the projection lens to form a projection pattern and is projected on a projection surface. In a conventional light machine, a light source is a part of the light machine, one or more light sources are fixedly arranged in a light path housing of the light machine, when the light source radiates heat, a heat pipe is directly connected with the light source or is in thermal connection with the light source through a heat radiation plate, heat generated by the light source is transmitted to one or more heat radiation fins by the heat pipe, the heat radiation fins or aluminum extrusion are generally adopted by the heat radiation fins, and then a cooling fan arranged in the housing of the projection equipment is used for cooling the heat radiation fins or the aluminum extrusion in an air cooling manner so as to achieve a cooling effect.
The heat pipe technology conducts the heat of the light source to the radiator, and then the heat is discharged to the external space of the projector through the fan. Because the light sources are distributed on different surfaces of the optical machine body, a plurality of heat pipes are needed to respectively dissipate heat of the light sources. The heat pipes are required to be bent for a plurality of times and then are connected to the radiator together, so that the length of the heat pipes is also increased, and the heat conduction efficiency of the heat pipes is greatly affected; meanwhile, the layout of a plurality of heat pipes occupies larger space, so that the stacking of the whole structure is influenced, and the requirement of smaller volume is not facilitated; the two ends of the heat pipe are respectively connected with the light source and the radiator, so that the heat pipe is complex to install, and large contact thermal resistance is easily caused by poor lamination, and the heat radiation efficiency is affected; the heat absorbed by the heat pipe is in direct proportion to the diameter of the heat pipe, and the larger the power consumption is, the larger the heat pipe is needed, the high cost is, and the space is occupied; the heat pipe and the radiator are integrally locked and attached on the optical machine, so that the installation and the disassembly are inconvenient.
Thus, the disclosed embodiments provide a heat dissipation system, see fig. 1, comprising an optical bench 5, a light source 2, a heat dissipation substrate 3, a light transmission device 4, etc. Referring to fig. 2, the optical engine 5 is provided with a plurality of light transmission device mounting portions 8, the number of which corresponds to the number of light sources required by the optical engine 5, for example, one light transmission device mounting portion 8 is provided for a single laser light source, three light transmission device mounting portions 8 are provided for three RGB light sources, and four light transmission device mounting portions 8 are provided for four RGB-BP light sources. The light transmission device mounting part 8 is an opening suitable for docking with the light transmission device 4, and the structure of an illumination light path inside the light machine is consistent with the conventional structure. When the optical transmission device mounting portion 8 is butt-mounted with the optical transmission device 4, a good optical sealing effect can be achieved, for example, the optical transmission device mounting portion may be in the form of screw butt-joint, sealing glue joint, or the like, which is not limited herein. In this form, the light source 2 is mounted separately from the light engine and is detachably or fixedly connected to the light source by the high-efficiency light transmission device 4. On the one hand, the light source 2 or the light transmission device 4 can be conveniently replaced under the condition of being detachable, and on the other hand, the heat of the light source 2 is far away from each lens in the optical machine 5, so that the working efficiency of the lens can be obviously improved, and the heat distortion effect is reduced.
The heat dissipation substrate 3 is provided with light source mounting parts 7 corresponding to the number of the light sources 2, and the light sources may be laser light sources or LED light sources, for example, the light source mounting parts 7 are grooves adapted to fix the light sources 2 thereon. Referring to fig. 3-4, the plurality of light source mounting portions 7 are arranged on the heat dissipation substrate 3 at intervals in a straight line or in a staggered manner, the intervals are equal or unequal, and the interval adjustment is aimed at adjusting the interval according to the heat dissipation amounts of different light sources, for example, the unit heat generation amount of the red light source is larger than that of the blue or green light source, and at this time, the interval between the red light source and other light sources can be properly increased, so that the heat can be more efficiently transferred to the heat dissipation substrate 3; the heat dissipation substrate 3 is thermally connected with the heat dissipation plate 1, and the heat dissipated by the light source can be transferred to the heat dissipation substrate 3 and then transferred to the heat dissipation plate 1, and the heat dissipation plate can be a heat dissipation fin or a heat dissipation aluminum extrusion. By adopting the mode, a plurality of different light sources are directly concentrated together to radiate, so that the radiating efficiency of the light sources can be remarkably improved.
Returning again to fig. 1, the light source 2 on the heat dissipating substrate 2 is optically connected to the optical engine 5 by an optical transmission device 4, and the optical transmission device 4 may be an optical fiber or a light pipe with high light guiding rate. To this end, in the overall design, the heat generating component light source 2 is separated from the optical engine 5, all of the light sources are disposed on one heat dissipating substrate 2, and then the heat dissipating substrate is cooled by a cooling member such as a fan or a water/liquid cooling mechanism. Of course, as required, the number of the heat dissipation substrates 2 may be two or more, specifically, two heat dissipation substrates 2 may be provided according to the number of light sources and the heat dissipation requirement, for example, at least one light source mounting portion 7 may be provided on each heat dissipation substrate 2, the number of the light sources 2 is still the same as that of the light source mounting portion 7 as a whole, the number of the light transmission devices 4 is also the same as that of the light sources 2, and the two heat dissipation substrates 2 may be respectively provided at different positions in the projection device, so as to further improve the heat dissipation efficiency.
In application, the light transmission device 4 can be made of flexible materials, and the diameter of the light transmission device is smaller than that of a heat pipe which needs to be adopted, so that the volume of an internal device of the projection device can be reduced, and support is provided for miniaturization of the projection device. On the other hand, the heat pipe is adopted to connect the two ends of the heat pipe to the light source 2 and the radiating fin 1 on the optical machine respectively, so that the heat resistance is reduced due to higher requirements on installation and assembly, dust is accumulated on the heat pipe along with the increase of the service time, the radiating efficiency is reduced, and when the two ends of the heat pipe are in poor contact with the light source 2 or the radiating fin 1, the radiating efficiency is obviously reduced.
According to another embodiment of the present disclosure, there is provided a projection device having the above heat dissipation system, the projection device further comprising a housing, a sound box system, various sensors, a light modulator heat sink, and the like. The optical machine 5 and the heat dissipation substrate 3 can be respectively and fixedly connected to the casing of the projection device, so that the fault tolerance is higher when the optical machine and the heat dissipation sheet 1 are integrated during assembly, and the influence of low assembly yield is reduced.
In the projection device, a cooling member that meets the requirement may be further disposed to cool at least one heat sink 1, for example, a fan may be disposed at a suitable position to cool the heat sink, or a liquid cooling assembly may be disposed around the heat sink 1. The fan can be arranged at an air inlet or an air outlet arranged on the projection equipment shell, and the purpose of air cooling is achieved by accelerating the air circulation of the shell. The liquid cooling assembly may comprise a cooling liquid, a condenser, cooling ducts etc. which are arranged around the cooling fin 1, thereby achieving a liquid cooling effect.

Accordingly, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present application are intended to be included within the scope of the present application.
