The technical scheme of the utility model is further described in detail below with reference to the accompanying drawings and examples.

As shown in fig. 1 to 4, an efficient fluorescent wheel motor heat dissipation device comprises a fluorescent wheel 1, a heat dissipation device support 3, an internal circulation fan 4 and a heat dissipation device 6, wherein the fluorescent wheel 1 is installed at the top of the heat dissipation device support 3 through the fluorescent wheel support 2, and the heat dissipation device support 3 is of a U-shaped frame structure. The fluorescent wheel 1 comprises a fluorescent wheel motor 11 and a fluorescent wheel aluminum disc 14, the fluorescent wheel motor 11 is arranged at the top of the radiator support 3 through the fluorescent wheel support 2, the output end of the fluorescent wheel motor 11 is rotationally connected with the fluorescent wheel aluminum disc 14 through a motor rotating shaft 12, and a ceramic plate 13 is arranged on the outer side face of the disc of the fluorescent wheel aluminum disc 14. The fluorescent wheel motor 11 which generates heat in the fluorescent wheel 1 is subjected to efficient heat dissipation, so that the fluorescent wheel motor meets the high-brightness requirement of a projector.

The inner circulation fan 4 and the radiator 6 are both arranged in the radiator support 3, wherein the inner circulation fan 4 is arranged in the radiator support 3 through the fan support 5, and the radiator 6 is mainly fixed through the radiator support 3. The air outlet of the inner circulation fan 4 faces the motor rotating shaft 12 of the fluorescent wheel 1, performs convection heat dissipation on the fluorescent wheel motor 11, and the heat absorption end of the radiator 6 faces the air inlet of the inner circulation fan 4, and performs conduction heat dissipation on the rest of heat in the radiator support 3. Therefore, the scheme organically combines two heat dissipation paths of conduction and convection together, complements each other, and has higher heat dissipation efficiency and higher efficiency. The heat on the rotating shaft of the fluorescent wheel motor can be quickly taken away, so that the volatilization of lubricating oil is prevented, and the motor is prevented from stalling and being damaged.

In the above-mentioned scheme, radiator 6 includes interior fin module 61, heat dissipation copper pipe 62, outer fin module 63, interior fin module 61 installs in the inside of radiator support 3, the bottom of interior fin module 61 is equipped with radiator support 7, outer fin module 63 installs in the bottom of radiator support 7, the heat absorption end of interior fin module 61 is towards the air intake of inner circulating fan 4 for form convection current heat dissipation, radiator support 7 is fixed mutually with the bottom of radiator support 3, radiator support 7 is platelike structure, can carry out bottom screw fixation with U type frame-like structure's radiator support 3. One side of the inner radiating fin module 61 is connected with the outer radiating fin module 63 through the radiating copper pipe 62, and is used for transferring heat absorbed by the inner radiating fin module 61 to the outer radiating fin module 63 through the radiating copper pipe 62 and discharging the radiator support 3, so that the normal operation of the fluorescent wheel 1 is not affected, and the high-brightness requirement of a projector is met.

The bottom of the radiator fixing support 7 is also provided with an outer circulation fan 8, and an air inlet of the outer circulation fan 8 is attached to the outer radiating fin module 63. The external circulation fan 8 can improve the heat conduction efficiency of the radiator 6, thereby further accelerating the heat dissipation efficiency and improving the heat dissipation effect. When the inner circulation fan 4 and the outer circulation fan 8 are implemented, fans with the same specification can be adopted, and a large flow fan is used, so that heat exchange is more sufficient, the heat dissipation wind flow is larger, and the heat dissipation points are directly aligned.
