Embodiment one：
As shown in Fig. 2 a kind of colour wheel radiator structure, including housing 1, colour wheel 2 and two air exhausting devices 3,
In housing 1, housing 1 includes two pairs of frames to colour wheel 2, and each pair frame is oppositely arranged, two air draft dresses
Put 3 to be separately positioned on the one pair of which frame of housing 1, and mutually stagger.It is provided with the two of air exhausting device 3
Two openings 101 are each provided with frame, four openings form two couples opening 101 of relative and interlaced arrangement,
An air exhausting device 3 is each provided with one pair of which opening 101, opening 101 on a two frames wherein frame,
The air exhausting device 3 arranged on another frame and space between the two respectively form an air channel.
Specifically, housing 1 includes four frames facing each other, on one pair of which two frames parallel to each other
Each to arrange two openings 101, another is to close frame 102 to two frames parallel to each other, four openings 101
Two couples opening 101 of relative and interlaced arrangement is formed, an air exhausting device is respectively set at one pair of which opening 101
3, on the opening 101, another frame on a two frames wherein frame arrange air exhausting device 3 and both with
Space between corresponding closing frame 102 respectively forms an air channel, i.e., the air channel of the left and right in figure two.
In the presence of corresponding air exhausting device 3, air-flow flows to the opening 101 of the other end from the opening 101 of air channel one end
And colour wheel 2 is exchanged heat.
Because two air exhausting devices 3 of the colour wheel radiator structure are separately positioned on housing one pair of which frame,
And be staggeredly arranged, therefore, will not interfere, good radiating effect can not only be realized, and
Can flexible arrangement air exhausting device, be conducive to adapting to less dimensional requirement.
In the present embodiment, colour wheel 2 is rotated counterclockwise, and two air exhausting devices 3 are towards the outside air draft of housing 1.
As shown in Fig. 2 using the figure direction as shown as standard, air flows into shell by the opening 101 of lower right side
In body 1 and flow out the airflow direction and right air channel airflow direction in (i.e. right air channel) from the opening 101 of upper right side
With linear velocity direction (i.e. tangential direction of the linear velocity in circumferential direction at the A) phase at points of tangency A of colour wheel 2
Together, air is flowed in housing 1 by the opening 101 of upper left side and flowed out from the opening 101 of lower left side (i.e. left
Air channel) airflow direction and left air channel airflow direction it is also identical with the linear velocity direction at points of tangency B of colour wheel 2,
The hot-air discharged from the opening 101 of upper right side due to preparation some follow the rotation of colour wheel 2 to go to a left side
The opening 101 of upside, due to the air exhausting device 3 connected at the rotation of colour wheel 2 and the opening 101 of lower left side,
The part hot-air is entered behind the air channel of the opening 101 of correspondence upper left side, with original air-flow side in the air channel
To being consistent, that is to say, that the airflow direction in two air channels with the linear velocity side of the circular motion of colour wheel 2
To identical, so as to the effect of this kind of arrangement is equivalent to air channel is separated, not only ensure radiating effect, and
Can flexible arrangement air exhausting device 3.
Above-mentioned colour wheel 2 can also be to rotate clockwise, and two air exhausting devices 3 are then towards the inside of housing 1
Air draft, can equally realize the airflow direction reality identical with the linear velocity direction of colour wheel circular motion in two air channels
Apply the technique effect of scheme.
Embodiment two：
As shown in figure 3, the present embodiment is with the difference of embodiment one, two air exhausting devices 3 are towards housing 1
Inside air draft, be provided with housing 1 for separate two air channels separation structure 4.
The embodiment is the preferred version of this specific embodiment, specifically, is found out by Fig. 3, and air is by the right side
The opening 101 of upside is flowed in housing 1 and flows out the air-flow in (i.e. right air channel) from the opening 101 of lower right side
Direction and right air channel airflow direction are in opposite direction with the linear velocity at the points of tangency A ˊ of colour wheel 2, and air is by lower left side
Opening 101 flow into housing 1 in and flow out the airflow direction in (i.e. left air channel) from the opening 101 of upper left side
It is also contrary with the linear velocity direction at the points of tangency B ˊ of colour wheel 2 with left air channel airflow direction.Due in two air channels
Airflow direction is in opposite direction with the linear velocity of the circular motion of colour wheel 2, is originally embodied as so as to colour wheel 2 has
Optimum convection transfer rate in mode.
This programme not only can greatly avoid enter into cold air in housing 1 still by arranging separation structure 4
Do not exchange heat and just overflow from adjacent opening 101, can also be avoided as much as by colour wheel 2 from an air channel
In the part hot-air taken away can liquidate with the original airflow direction in this air channel when into another air channel.
In the present embodiment, separation structure 4 is connected in for one end and is provided with the other end on the frame of opening 101
Near the demarcation strip of colour wheel 2, simple structure, segregation are good.
Demarcation strip need to be positioned as close to colour wheel 2, to ensure preferable segregation.
In the same manner, above-mentioned colour wheel 2 can also be to rotate clockwise, and two air exhausting devices 3 are then towards housing 1
Outside air draft, can equally realize the airflow direction in two air channels and the linear velocity direction of colour wheel circular motion
The technique effect of contrary embodiment.
Embodiment three：
As shown in figure 4, the present embodiment is with the difference of embodiment one, two air exhausting devices 3 are respectively towards shell
The outwardly and inwardly air draft of body 1, is provided with the separation structure 4 for separating two air channels in housing 1.
In the present embodiment, air channel needs to separate by separation structure 4, because two air channel airflow directions one
Cause, the part hot-air taken away from an air channel by colour wheel 2 can be former with this air channel when into another air channel
Some airflow directions liquidate.That is, the wherein airflow direction in an air channel in two air channels and should
Bar air channel airflow direction is identical with the linear velocity direction at the points of tangency of colour wheel 2, the airflow direction in another air channel
It is in opposite direction with the linear velocity at the points of tangency of colour wheel 2 with the air channel airflow direction.
In the present embodiment, separation structure 4 is connected in for one end and is provided with the other end on the frame of opening 101
Near the demarcation strip of colour wheel 2, simple structure, segregation are good.
Due to the rotation and the air draft of air exhausting device 3 of colour wheel 2, according to the direction of rotation of colour wheel 2 by reasonable
The air draft direction of air exhausting device 3 is set to realize separating air channel, so as to both ensure radiating, and can flexible arrangement
Air exhausting device 3 is adapting to less dimensional requirement.
When colour wheel 2 is changed to rotate clockwise, the exhaust way of two air exhausting devices 3 can respectively do adaptability
Change, equally can also realize the linear velocity side of the wherein airflow direction in an air channel and the circular motion of colour wheel 2
To identical, the airflow direction in another air channel and the linear velocity embodiment in opposite direction of the circular motion of colour wheel 2
Technique effect.
