As shown in Figure 1 and 2, the communication device enclosure cooling apparatus by a separate heat pipe according to the present invention is provided inside the housing 10 equipped with a communication device or an electronic device, the liquid main body in the horizontal direction ( 13) and a plurality of vertical pipes (12) having a heat dissipation fin (121) and branched vertically from the liquid main pipe (13) and the steam pipe connected in the horizontal direction to the top of the vertical pipes (12) It is provided on the evaporation unit (1) and the outer housing 10, which is composed of (11), branched from the liquid main pipe 33 and the liquid main pipe 33 in the horizontal direction on one side, standing vertically and radiate heat (fin) At least one heat dissipation part (3) consisting of a plurality of vertical pipe (32) having a 321 and the steam main pipe 31 connected to the upper end of the vertical pipe 32 in the horizontal direction, and the steam main pipe ( 11) and one or more ramps connecting the steam main part 31 of the heat dissipation part. It consists of a connecting pipe (5), at least one liquid connecting pipe (7) connecting the liquid main pipe (13) of the evaporator and the liquid main pipe (33) of the heat dissipation unit.

As described above, the evaporator 1 composed of the liquid main body 13, the plurality of vertical tubes 12, and the steam main body 11 includes a fan 2 inside the enclosure 10 in which a communication device or an electronic device is embedded. And heat generated from the communication device is in contact with the evaporator 1 by the fan 2 inside the enclosure and exchanges heat to evaporate the working fluid contained in the vertical pipe 12 to the interior of the enclosure.
