Abstract: The present disclosure relates to a cooler and to a display device having the same, where a heat-exchanger of the cooler is arranged on a side surface of a display unit in order to simplify the structure and to make a slimmer display device. The cooler includes a closed air circulation pathway circulating between the front, rear and sides of the display unit; an open air flow pathway that flows in the length direction of the side of the display unit; and a cooling module that is installed on the side of the display along the length direction of the display, and that includes the heat-exchanger, where the closed air circulation path and the open air flow part are adjacent, thereby causing heat-exchange.

Abstract: The present invention relates to: a cooler capable of simplifying a structure, increasing heat exchange efficiency, and slimming a display device; and a display device using the same. A cooler structure applied to the display device uses a heat pipe allowing a refrigerant, which is a volatile liquid, to flow therein and a fin structure expanding a heat transfer cross section, so as to rapidly absorb, through evaporation of the refrigerant, heat from the air in a closed air circulation path circulating around a display unit, and quickly dissipate heat from an outside space (an open air circulation path) of the closed air circulation path through condensation of the refrigerant, thereby enabling heat exchange to occur very efficiently while occupying less volume. Additionally, the present invention provides the cooler structure in which the heat pipe is made in a circular fashion such that the refrigerant efficiently flows therein. Particularly, when a section in which the heat pipe generates heat is disposed on the side of the display unit, the display device can be formed to be just as slim.
