Abstract: A watch type mobile terminal includes a main body configured to include an electric apparatus unit in which an electronic part is mounted, a band configured to be worn on a wrist of a user in a manner of being combined with the main body, a heat pipe configured to include a first pipe positioned at the main body and a second pipe positioned at the band wherein the first pipe and the second pipe forms a loop in a manner of being connected with each other, a first working fluid injected into the heat pipe and a second working fluid different from the first working fluid in density. The watch type mobile terminal can emit heat of the main body at the band using the heat pipe.

Abstract: A mobile terminal having a structure increasing heat dissipation efficiency, including a printed circuit board (PCB) disposed within a terminal body and having a heating element which generates heat mounted thereon, a frame having a space formed on one surface thereof and allowing the PCB to be installed therein, and a heat pipe supported by the frame, disposed on one surface of the frame, and connected to the PCB to dissipate heat generated by the heating element outwardly from the terminal body, wherein the frame includes a hold portion extending from an end portion thereof to cover at least a portion of the heat pipe in order to prevent the heat pipe from being released from the frame by external force applied to the terminal body.

Abstract: There is disclosed a mobile terminal including a case comprising a control portion provided therein, a display coupled to the case, a main circuit board mounted in a predetermined portion of the control portion, a heat exchanger having a portion arranged adjacent to the main circuit board, with a plurality of micro-paths extended from the portion to the other portion, each of the micro-paths connected to a neighboring one to form a closed loop, and a working fluid configured to absorb heat in the portion and emit the heat in the other portion, to be liquefied, the working fluid configured to vibrate along the micro-paths, wherein a gaseous state working fluid and a liquid state working fluid are mixed intermittently.
