Disclose in graphic, be a kind of radiating module structure of projection arrangement, it comprises:

One projection arrangement 100 is optical engine module 1 of being located in the projection arrangement 100 by one;

One is located at the projection module 2 of these optical engine module 1 one sides; And

One is located at 3 compositions of radiating module between optical engine module 1 and the projection module 2;

Wherein, said radiating module 3, it is the fan of being located between optical engine module 1 and the projection module 2 by one 31; One is located at the heat conductor 32 at these fan 31 1 side places; And one be located at these heat conductor 32 1 ends and with corresponding each other 33 compositions of heat-conducting block that also can absorb thermal source of optical engine module 1.

Wherein, cold air is imported, in order to increase the air mass flow in the projection arrangement 100 and to reduce the temperature of projection arrangement 100 built-in systems through fan 31.

Secondly,, make the utility model can reach better heat radiating effect, and effectively promote the System Operation in the projection arrangement 100 through the enforcement that cooperates of heat conductor 32 with heat-conducting block 33.

In above-mentioned, said heat conductor 32 is by an elongated conduit 321; And one be sheathed on these conduit 321 1 ends 322 compositions of sheet fin.

Wherein, said fin 322 is for one of following: ㄈ shape fin, degree of lip-rounding fin, straight shape fin.

Wherein, through the cooperate enforcement of fin 322, can projection arrangement 100 inner heats be discarded to the outside with conduit 321.

In above-mentioned, a side of said heat-conducting block 33 is provided with a groove 331, in being sheathed on for the conduit 321 of the strip of heat conductor 32 1 ends.This side of heat-conducting block 33 combines with the side plate 11 of optical engine module 1 side again, and the conduit 321 of strip that makes heat-conducting block 33 is by sheathed fixing and movability not.
