That is, when the fastening bolt 4252 is installed in place, the nut of the fastening bolt 4252 does not abut against the rear sealing plate 43, but abuts against the reinforcing rib 425. In this way, after the laser device 200 is connected with the machining platform, the rear sealing plate 43 cannot be directly opened, which affects the replacement efficiency of the laser module 100 and the heating module. Alternatively, the rear sealing plate 43 is also provided with a positioning pin, and the reinforcing rib 425 is provided with a rear sealing plate 43 adjusting hole 4112 corresponding to the positioning pin.

[0081] As can be understood, when the fan 53 is running, air flows along the gap between two adjacent heat dissipation fins 511. The plurality of heat dissipation fins 511 are arranged at intervals along the extension direction of the outer air duct 42, so that the air inlet 4211 and the air outlet 4231 on the outer air duct 42 can be opposite to the gap between two adjacent heat dissipation fins 511, reducing the resistance of air flow, enhancing the wind speed, and improving the heat dissipation effect.

[0084] As can be understood, in order to increase the contact area of the heat dissipation fins 511 with air, the side surface of the heat dissipation fins 511 forms the outer surface of the first heat dissipation member 51 and the second heat dissipation member 52, and the first sealing plate 56 and the second sealing plate 57 are respectively adhered to the surfaces of the first heat dissipation member 51 and the second heat dissipation member 52 which are not opposite to the air inlet 4211 or the air outlet 4231, so as to close the gap between two adjacent heat dissipation fins 511 which is not opposite to the air inlet 4211 or the air outlet 4231, and form the heat dissipation channel 58.
