That is, the color wheel substrate 100, the color wheel fluorescent part 200, the plurality of blades 300, and the current collecting plate 400 form a fixed whole. The color wheel heat dissipation device 10 further includes a driving assembly 500 disposed in the inner ring of the color wheel substrate 100 and connected to the color wheel substrate 100, and the driving assembly 500 may be configured to integrally drive the color wheel substrate 100, the color wheel fluorescent portion 200, the plurality of blades 300, and the current collecting plate 400 to rotate around the central axis of the color wheel substrate 100.

And the color wheel fluorescent portion 200 may be fixed to the color wheel substrate 100 by sintering, so that the heat conduction effect between the color wheel fluorescent portion 200 and the color wheel substrate 100 may be enhanced, and further, the heat dissipation effect of the color wheel fluorescent portion 200 may be enhanced.
As shown in fig. 5 and 6, the current collecting plate 400 is further provided with an annular groove 410, and the annular groove 410 is disposed around the central axis of the color wheel substrate 100.
As shown in fig. 7 and 8, during the rotation of the plurality of blades 300 driven by the driving assembly 500, the air flow in the air intake area enclosed by the inner sides of the plurality of blades 300 flows out through the air flow channel and through the outer sides of the plurality of blades 300, and at this time, the air intake area forms a low pressure area, and the air flow of the entire color wheel heat dissipation device 10 enters the low pressure area and continues to flow out through the air flow channel and through the outer sides of the plurality of blades 300.
As shown in fig. 8, the external air enters the air inlet area of the color wheel heat dissipation device 10, then the air flow in the air inlet area enters the inner sides of the plurality of blades 300, and then flows out from the outer sides of the blades 300 through the air flow channels formed by the plurality of blades 300, which is a movement from an axial movement to a radial movement, after the air flow enters the air flow channels formed by the plurality of blades 300, the axial movement cannot be quickly converted into a radial movement, so that a low-speed vortex occurs, and the air flow cannot quickly flow out from the outer sides of the plurality of blades 300, thereby affecting the heat dissipation effect. And further, by providing the annular groove 410 at the current collecting plate 400, the weight of the current collecting plate 400 can be reduced, thereby reducing the load of the driving assembly 500, reducing energy loss, and reducing heat dissipation requirements.
As shown in fig. 8, after the airflow enters the airflow channel formed by the plurality of blades 300, a low-speed vortex is formed near the inner side of the plurality of blades 300, and as shown in fig. 9, by providing the annular groove 410, the external airflow may go into the blades 300 through the annular groove 410, thereby disturbing the low-speed vortex.

In an alternative embodiment, the radial width of the annular groove 410 is less than or equal to one-quarter of the overall radial width of the collector plate 400. For example, the annular groove 410 may have an inner diameter of 76mm and an outer diameter of 82 mm. Alternatively, the inner diameter of the annular groove 410 may be 82mm, the outer diameter may be 88mm, etc., without limitation.
In an alternative embodiment, the radial spacing between the annular groove 410 and the inner annular surface of the collector plate 400 is less than the radial spacing between the annular groove 410 and the outer annular surface of the collector plate 400. I.e., the annular groove 410 is closer to the inner side of the collecting plate 400, so that it is possible to better break the low-speed vortex located at the inner side of the vane 300.
As shown in fig. 10, in an embodiment, the inner diameter of the collecting plate 400 is greater than or equal to the inner diameter of the plurality of blades 300, and the outer diameter of the collecting plate 400 is less than or equal to the outer diameter of the plurality of blades 300. The inner diameter of the plurality of blades 300 is the inner diameter of the entire plurality of blades 300, and the outer diameter of the plurality of blades 300 is the outer diameter of the entire plurality of blades. That is, the collector plate 400 covers only a portion of the blades 300 in the radial direction, so that the weight of the collector plate 400 can be reduced, thereby reducing the load of the driving assembly 500, reducing energy loss, and reducing heat dissipation requirements.
In an alternative embodiment, the radial width of the collecting plate 400 is greater than or equal to one-half of the radial width of the blade 300. For example, the blades 300 may have an inner diameter of 72mm, an outer diameter of 100mm, and a radial width of 28 mm; the collector plate 400 may have an inner diameter of 76mm, an outer diameter of 96mm, and a radial width of 22 mm.
In an alternative embodiment, the projection area of the orthogonal projection of the current collecting plate 400 on the color wheel substrate 100 is greater than or equal to one half of the maximum area enclosed by the projection of the blade 300 on the color wheel substrate 100. Specifically, since the plurality of blades 300 are arranged at intervals, that is, there is a gap area between the plurality of blades 300, the maximum area enclosed by the projection of the blades 300 on the color wheel substrate 100 is the sum of the areas of the plurality of blades 300 and the gap area between the blades 300.
The working principle is explained with respect to the above structure:
when the driving assembly 500 drives the plurality of blades 300 to rotate, due to the centrifugal action of the plurality of blades 300, the airflow between the blades 300 is accelerated and flows out from the outer side of the blades 300, the speed of the airflow is in an ascending gradient in the radial direction from inside to outside, and the pressure of the airflow is also in an ascending gradient, that is, the inner side area of the blade 300 is the area with the lowest pressure, that is, the air inlet area, due to the action of the collecting plate 400, the blade 300 does not work on the airflow away from the color wheel substrate 100, and further, a vortex low pressure is not generated, that is, the airflow of the area of the collecting plate 400 away from the color wheel substrate 100 is close to a standard atmospheric pressure, so as to generate a pressure difference with the air inlet area of the inner side of the blade 300, and the airflow of the area of the collecting plate 400 away from the color wheel substrate 100 rapidly moves axially under the pressure difference to enter the air inlet area of the blades 300, finally, a high-speed airflow is formed and flows out from the outer side of the blade 300, thereby driving the heat of the color wheel substrate 100 and the blade 300, and further dissipating the heat of the color wheel fluorescent part 200 and the driving assembly 500.
The present application further provides a projection device, which includes the color wheel heat dissipation apparatus 10 described in any of the above embodiments.
To sum up, this application covers the current collector through keeping away from one side of colour wheel base plate at a plurality of blades, on the one hand, can avoid the blade to produce the swirl low pressure flow in the direction of keeping away from the colour wheel base plate at the blade when carrying out high-speed rotation, and then reduce the regional influence of admitting air to the blade inboard for the inboard regional air velocity field and the pressure field of keeping uniform of admitting air of blade, thereby improve the air input, in order to improve the radiating effect. Meanwhile, the flow direction of the airflow can be well controlled by arranging the collector plate, and the backflow of the airflow is reduced, so that the airflow is prevented from directly entering the blade without being processed by a cooling area after flowing out of the blade, and the heat dissipation effect is prevented from being influenced. Furthermore, certain heat exchange can be carried out with air flow and blades through setting up the current collector to improve whole heat radiating area, and then improve the radiating effect. On the other hand, the end part of the blade is partially closed by the collecting plate, so that the noise generated by the impact of the airflow on the end part of the blade can be reduced. On the other hand, can also further set up the ring channel on the collector plate to thereby can make in the outside air current enters into the blade from the ring channel and disturb low-speed vortex, and then improve the homogeneity and the air input of air current, in order to improve the radiating effect.
