  • Patent number: 10905036
    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.
