The present invention relates to a cooling device assembly for an LED lighting mechanism, which is configured to include: an LED lighting mechanism mounting plate (300); a heat pipe (400) fixed to the side opposite the surface in which the lighting mechanism mounting plate is fixed; and a radiation fin (500) mechanically compressed and fixed to the outside of the heat pipe (400). At least one fixing hole (320) is formed in the LED lighting mechanism mounting plate (300), and the heat pipe (400) is fixed vertically backward to the mounting plate using a fastening bolt (310). One side end of the heat pipe (400) is configured such that a close contact pipe (441) positioned inside the heat pipe is made to have a circle perimeter bent part (451), and an inside pipe (442) pressurized and inserted into the close contact pipe (441) and having a nut thread (410) so that the fastening bolt (310) can be fixed into the close contact pipe (441). The other side end of the heat pipe (400) is configured such that a close contact pipe (446) positioned inside the heat pipe is made to have a circle perimeter bent portion (452), and an inside pipe (445) pressurized and inserted into the close contact pipe (446) and having a nut thread (420) so that a cap bolt (430) can be fixed into the close contact pipe (446). The cooling device assembly for an LED lighting mechanism including a heat pipe and a radiation fin according to the present invention further includes: a peak cap bolt (447) which is inserted in advance into the nut thread in the inside pipe (445) and which is filled therein so that a working fluid filling the inner space of the heat pipe does not flow out; silicone (440) having high heat transmission efficiency as a safety device which blocks air from flowing into the inner space of the heat pipe (400) before the filling of the cap bolt; and a working fluid leak prevention cap bolt (430). |
