[0001] The utility model relates to the technical field related to projectors, in particular to a projector optical machine radiator, and also provides a projector optical machine. Background Art

[0002] With the popularization of electronic devices, projectors have gradually come into the public eye. Projectors have advantages such as large display area and easy portability. They are often used in conferences, teaching, presentations and other occasions. At the same time, they have gradually begun to enter private homes. More and more people intend to use projectors to replace TVs as home audio and video equipment. However, traditional projectors currently have the following disadvantages:

[0003] At present, traditional projector optical machine radiators are generally designed and assembled with a radiator and a cooling fan as separate parts. However, such a design scheme cannot ensure the heat dissipation effect, and the radiator and the cooling fan cannot be designed to be too small, which will lead to poor heat dissipation effect. On the other hand, the radiator and the cooling fan still need to be assembled, which not only reduces the assembly efficiency of the entire optical machine, but also increases the cost. Utility Model Content

[0004] In view of the above problems existing in the prior art, the projector optical engine heat sink and the projector optical engine provided by the present invention are used to overcome the above defects in the prior art.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present utility model is as follows:

[0006] The projector optical radiator includes a radiator shell made of aluminum alloy material, a circular first groove is provided on one side of the radiator shell, a fan blade is rotatably provided inside the first groove, and a plurality of through holes are provided on the bottom wall of the first groove.

[0007] In one embodiment, a portion of the bottom wall of the first groove protrudes outward to form a second groove, the top of the second groove is a plane, and a plurality of through holes are respectively provided on the bottom wall of the second groove and the side wall below the top thereof.

[0008] In one embodiment, the through hole on the bottom wall of the second groove is circular, and the through holes on the bottom wall of the first groove and the side wall of the second groove are rectangular.

[0009] In one embodiment, a plurality of through holes located on the bottom wall of the first groove and the side walls of the second groove are respectively distributed in a circular array about the center point of the first groove.

[0010] In one embodiment, a plurality of first vertical plates are provided on the inner side wall of the bottom of the second groove, and the plurality of first vertical plates are distributed in a circular array about the center point of the first groove.

[0011] In one embodiment, a plurality of second vertical plates are respectively provided on the outer walls around the first groove and on the outer walls below the top of the second groove, and the plurality of second vertical plates on the outer walls of the first groove and the plurality of second vertical plates on the outer walls of the second groove are respectively distributed in a circular array about the center point of the first groove.

[0012] In one embodiment, a plurality of second vertical plates located on the outer side wall of the second groove are connected to a portion of the second vertical plates located on the outer side wall of the first groove in a one-to-one correspondence and are integrated into one body.

[0013] In one embodiment, lower surfaces of a plurality of second vertical plates located below the outer side wall of the second groove are located on the same plane.

[0014] In one embodiment, a fan blade mounting plate is provided inside the first groove, and the outer side wall of the fan blade mounting plate is flush with the outer side wall of the radiator shell. Several connecting rods are provided around the fan blade mounting plate, and one end of the several connecting rods away from the fan blade mounting plate is connected to the radiator shell, and the fan blades are rotatably mounted on the inner side wall of the fan blade mounting plate.

[0015] The present invention also provides a projector optical engine, comprising a projector optical engine main body, characterized in that a projector optical engine radiator as described above is provided on one end of the projector optical engine main body.

[0016] Compared with the prior art, the projector optical engine heat sink provided by the present invention includes a heat sink housing made of an aluminum alloy material, a circular first groove is provided on one side of the heat sink housing, a fan blade is rotatably provided inside the first groove, and a plurality of through holes are provided on the bottom wall of the first groove. In this way, the heat sink and the heat dissipation fan are combined into one. The heat generated by the projector optical engine can be directly transferred to the heat sink housing and then directly dissipated by the fan blades. Compared with the traditional combination of a heat sink and a heat dissipation fan, the heat transfer distance is shorter, and the fan blades can more directly dissipate heat from the heat sink housing, thereby improving the heat dissipation efficiency. At the same time, due to the reduction of parts and the simplification of the assembly process, the production efficiency can be greatly improved and the cost can be reduced.

[0017] Secondly, the integrated design of the radiator and cooling fan greatly reduces the volume of the entire optical machine, which is more conducive to the miniaturization design of the entire projector. BRIEF DESCRIPTION OF THE DRAWINGS
