[0019] In some embodiments, the wiring portion includes a first wiring port 6, a second wiring port 7, and a third wiring port 8, and the heat conductive portion includes a first heat conductive block 9 and a second heat conductive block 10. The first heat conductive block 9 is connected and arranged on one side of the first wiring port 6 and the second wiring port 7, and the second heat conductive block 10 is arranged on one side of the third wiring port 8. The first slot 2 is arranged on the outside of the first heat conductive block 9 and the second heat conductive block 10. A general optical machine 1 has three or more data interfaces. The present application transfers the generated heat to the heat conductive pipe body 3 by arranging the first heat conductive block 9 and the second heat conductive block 10 at the data interface (i.e., the first wiring port 6, the second wiring port 7, and the third wiring port 8).

[0020] In some embodiments, the heat-conducting pipe body 3 is a copper tube, and the heat-conducting liquid is diethylene glycol. The diethylene glycol is sealed in the copper tube. Copper has a high thermal conductivity, which accelerates the heat transfer rate. Diethylene glycol is another liquid with good thermal conductivity, and its thermal conductivity coefficient is about 0.27W / (m*K). In addition, diethylene glycol also has the advantages of good stability, fluidity and low cost.

[0021] In some embodiments, a plurality of heat dissipation fins are arranged on the outside of the heat dissipation channel 4, the second slot body 5 matches the shape of the heat conduction pipe body 3, the heat dissipation channel 4 and the heat dissipation fins are made of copper, and heat dissipation fins are arranged outside the heat dissipation channel 4 to accelerate the heat dissipation effect.

[0022] In some embodiments, two first grooves 2 are provided on the outside of the heat conduction part, and heat pipes 3 are provided in the two first grooves 2 respectively; two second grooves 5 are provided in the heat dissipation channel 4. The provision of two heat pipes 3 can improve the heat dissipation efficiency.

[0023] In some embodiments, the first heat-conducting block 9 and the second heat-conducting block 10 are made of copper, which has a high thermal conductivity and accelerates the heat transfer speed.

[0024] In some embodiments, a heat dissipation port 11 is provided on one side of the box body, and the heat dissipation channel 4 is disposed inside the heat dissipation port 11 , so that heat is radiated to the outside of the projector through the heat dissipation port 11 .

[0025] The specific heat dissipation principle of the present application is as follows: when the optical machine 1 works, a large amount of heat is generated at the wiring part, and the heat is conducted to the heat-conducting part, and then transferred to the heat-conducting pipe body 3. The heat-conducting liquid in the heat-conducting pipe body 3 exchanges heat, and one end absorbs the heat of the heat-conducting block, and the other end radiates the heat into the air through the heat dissipation channel 4.

[0026] The present application transfers the heat generated by the wiring part to the heat-conducting pipe body 3 through the heat-conducting part. The heat-conducting liquid in the heat-conducting pipe body 3 takes the heat away and dissipates it through the heat dissipation channel 4. The heat-conducting liquid exchanges heat in the heat-conducting pipe body 3 and can quickly take away the heat, ensuring that the mapping effect of the optical machine 1 is not affected, thereby extending the service life of the projector.
