As described in Figure 2, first face (towards right face in Fig. 2) of housing 101 of receiving thermal source has air outlet 101a, with
The second adjacent face of first face (face directed downwardly in Fig. 2) has air inlet 101b.As shown in figure 1, the housing 101 accommodating thermal source wraps
Include the first housing 101c and the second housing 101d, the first housing 101c is the top half housing of the housing 101 accommodating thermal source, the
Two housing 101d are the latter half housing of the housing 101 accommodating thermal source, and the inside accommodating the housing 101 of thermal source is provided with dividing plate
106, the first housing 101c and the second housing 101d with dividing plate 106 as line of demarcation, in dividing plate 106 and the first housing 101c enclose
Put air channel 105, dividing plate 106 and the second housing 101d enclose the cavity accommodating colour wheel.The one end in built-in air channel 105 and air inlet
101b connects, and dividing plate 103 is provided with air port away from one end of air inlet 101b, and built-in air channel 105 is led to the housing 101 accommodating thermal source
Cross air port UNICOM, the cold air entering from air inlet 101b can be caused the diagonally opposing corner air port of air outlet 101a by built-in air channel 105
Place, then import in the cavity accommodate colour wheel so that cold air diagonally flows in receiving colour wheel cavity from air port, have more
Good radiating effect.
The thickness of the first housing 101c is more than the thickness of the second housing 101d, and the wall thickness in built-in air channel 105 can be according to reality
Demand is arranged, and the duct cross-section in built-in air channel 105 amass constant it is ensured that air-flow in built-in air channel 105 steadily simultaneously
So that the overall dimensions accommodating the housing of thermal source reach minimum, in addition, the appearance of the housing 101 of receiving thermal source being thusly-formed
The structure that face fills for ladder, has reserved space outside the second housing 101d for installing the optics of colour wheel, has effectively saved
Space is so that structure is compacter.
Heat exchanger 104 has air inlet and air outlet, and the air outlet of heat exchanger 104 is entered with the housing 101 accommodating thermal source
Air port 101b UNICOM.
External air channel 103 includes the first air channel 103a and the second air channel 103b, the first air channel 103a and the second air channel 103b
Become " 7 " font connect, the first air channel 103a with accommodate thermal source housing 101 air outlet 101a UNICOM, the second air channel 103b with
The air inlet UNICOM of heat exchanger 104.Fan 102 is arranged on the second air channel 103b, and fan 102 includes driving means and blade,
The output end of driving means is connected with blade, and the blade of fan 102 is arranged in the second air channel 103b, and fan 102 drives external
Air flow heat exchanger 104 in air channel 103, that is, drive and for the hot-air in the housing 101 accommodating thermal source to be extracted into heat exchanger 104
In carry out heat exchange.
The height of heat exchanger 104 is higher than the height of the first air channel 103a, and this highly refers to heat exchanger 104 or the first air channel
The bottom surface of 103a to top surface ultimate range, and the height ratio of the height of heat exchanger 104 and the first air channel 103a be more than etc.
In 1.1, that is, the height of the first air channel 103a is less than the height of heat exchanger 104 so that the first air channel 103a upper end forms certain sky
Between radiated by heat exchanger 104 for system wind.In order to improve the radiating effect of system wind heat exchanger 104, first
The top of air channel 103a or bottom are in curved surface, the portion smooth transition arranging chamfering or connecting two faces in edges and corners,
The system wind energy of making enough more smoothly passes over the first air channel 103a.Or the first air channel 103a is in concave structure, middle sinking, give
System wind provides bigger airspace.The curved-surface structure of the first air channel 103a or concave structure all improve the exchange of system wind
The radiating effect of hot device 104.
The length of heat exchanger 104 is equal to or approximately equal to the length of the first air channel 103a it is commonly known that heat exchanger 104 face
Amass more big more be beneficial to radiating, but be as the miniaturization of equipment it is desirable to heat exchanger 104 will to the greatest extent may be used in the case of as little as possible
The big performance heat dispersion of energy, for this reason, the length of heat exchanger 104 is arranged to air channel equal length, the height of heat exchanger 104
More than the height of the first air channel 103a, preferably serve the purpose that thermolysis has also reached compact conformation simultaneously.
By the spacing between the long-term research discovery heat exchanger 104 of inventor and the first air channel 103a to projector equipment
The setting of integral heat sink runner has material impact, and the minimum spacing between heat exchanger 104 and the first air channel 103a is more than or equal to
20mm, holds and so both can guarantee that projector equipment radiating flow passage overall flow resistance was minimum, also can make the miniaturization of heat abstractor and dissipate
The high efficiency of heat.
Heat exchanger 104 and the first air channel 103a upper surface are below accommodating housing 101 upper surface of thermal source, heat exchanger 104
Concordant with the upper surface of the second air channel 103b with the upper surface of the first air channel 103a.Heat exchanger 104 and the first air channel 103a reserve
The space of one projector equipment heat dissipation wind channel.
The heat abstractor that the present embodiment provides, is provided with built-in air channel 105, built-in wind due to accommodating in the housing 101 of thermal source
Road 105 will be arranged on the first face of the housing accommodating thermal source with air outlet 101a, and air inlet 101b is arranged on and accommodates thermal source
The second adjacent face of housing 101, the outlet in built-in air channel 105 is guided to the position at this air outlet 101a diagonal so that holding
Receive thermal source housing 101 internal gas flow from diagonal flow, diagonal form flowing air can avoid outlet and inlet short circuit,
Inside cavity is not in cold wind dead angle, therefore good heat dissipation effect, and air inlet 101b and air outlet 101a is arranged on the same side,
Air inlet 101b can directly be docked with the air outlet of heat exchanger 104, eliminates an external channel, reduces colour wheel heat-exchanger rig
External structure volume, finally makes whole colour wheel heat-exchanger rig compact conformation, has saved and used space, little beneficial to whole device
Type.
