Abstract: The present disclosure provides a wireless communication antenna structure for both heat dissipation and radiation which includes: an inside helical pattern including an inside start end and an inside tail end; an outside helical pattern including an outside start end and an outside tail end; a heat dissipating/radiating metal layer including one side metal region and the other side metal region; and a plurality of via holes respectively connecting, up and down, the inside tail end and the one side metal region, and the outside start end and the other side metal region, so that the inside helical pattern, the heat dissipating/radiating metal layer and the outside helical pattern are connected in sequence to be a helical type. The present disclosure also implements heat dissipation of various components inside a portable terminal while implementing better near field wireless communication.

Abstract: The present invention discloses a heat cooler including a lower member and an upper member attached to each other and a vacuum cavity interposed between the lower member and the upper member, wherein the working oil is filled within the vacuum cavity, and the working oil is phase-change circulated within the vacuum cavity according to an external temperature. The present invention implements minimization of an occupied space and implements a light and small device according to a simple constitution, thereby guaranteeing maximization of productivity and heat dissipation.
