Then it is necessarily required to the plug division 422 of second connecting portion 421 and second being vertically arranged.
It should be noted that the above-mentioned plug division 422 of second connecting portion 421 and second is vertically arranged only a kind of preferred reality
Mode is applied, the plug division 422 of second connecting portion 421 and second is in addition to being set to mode connected vertically, or other
The connection of angle, user can set both connection angles according to specific use, as long as enabling to the second radiation
Baffle 410 can absorb heat produced on colour wheel 500.
Please continue to refer to Fig. 2, specifically, the first radiation absorption plate 210 includes the first copper coin and is coated in described the
The first radiation absorption layer 211 on one copper coin, the second radiation absorption plate 410 includes the second copper coin and is coated in described second
The second radiation absorption layer 411 on copper coin.
The above-mentioned radiation absorption layer 411 of first radiation absorption layer 211 and second is set, is to improve the first radiation absorption plate
210 and second radiation absorption plate 410 absorptive thermal radiation ability, and then improve colour wheel 500 provided by the present invention radiating dress
The radiating efficiency put.
Preferably, first radiation absorption layer 211 and second radiation absorption layer 411 are polymer composite
Layer.
The material of first radiation absorption layer 211 and the second radiation absorption layer 411 is set to polymer composite, be because
Ability for its absorption radiation is preferable, and polymer composite can select graphite powder or nanometer carbon coating, then by graphite
Powder or nanometer carbon coating are coated on the first radiation absorption plate 210 and the second radiation absorption plate 410, and polymer composite is removed
Beyond above two selection, can also for other raising thermal radiation effects material layer, such as black nickel dam, pitch-dark layer, as long as
The absorptive thermal radiation ability of the first radiation absorption plate 210 and the second radiation absorption plate 410 can be improved.
It should be noted that the radiating effect in order to improve the colour wheel heat abstractor that the embodiment of the present invention is provided, is used
Person can install ventilating fan or extraction fan in the running space of colour wheel 500, also can be in the outside of whole colour wheel heat abstractor
Ventilating fan or extraction fan are installed, entered to enable the heat produced by colour wheel 500 to form convection current by the ventilating fan of setting,
Further improve rate of heat dispation.
Further, the embodiment of the present invention also provides a kind of cooling system, including colour wheel heat abstractor as described above.
The cooling system compared to prior art beneficial effect, with above-mentioned colour wheel heat abstractor compared to prior art
Beneficial effect it is identical, here is omitted.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
