A heat conduction apparatus includes a first cover plate and a second cover plate. The first cover plate is hermetically connected to the second cover plate. The first cover plate is provided with a plurality of grooves. A supporting portion is formed between two adjacent grooves. A liquid circulation channel and a vapor circulation channel are formed in the groove. The liquid circulation channel is filled with a liquid working medium. The liquid circulation channel is communicated with the vapor circulation channel. The liquid working medium vaporizes into vapor. The vapor enters the vapor circulation channel and condenses into liquid. The liquid enters the liquid circulation channel.

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.

The first heat pipe includes first end part and second end part that are opposite to each other. The second end part includes inner peripheral wall and outer peripheral wall surrounding the inner peripheral wall. A vapor channel is formed between the outer peripheral wall and the inner peripheral wall. The inner peripheral wall forms insertion hole. A central line of the insertion hole is at first distance from the outer peripheral wall along first direction. The central line of the insertion hole is at second distance from the outer peripheral wall along second direction. The first direction is different from the second direction, and the first distance is different from the second distance.

A cooling device includes an evaporator configured to evaporate working fluid in a liquid phase due to a heat transferred from a cooling target, a condenser configured to condense the working fluid in the vapor phase, a vapor pipe through which the working fluid changed to the vapor phase in the evaporator flow into the condenser, and a liquid pipe through which the working fluid changed to the liquid phase in the condenser flow into the evaporator. The condenser has a phase change flow channel into which the working fluid in the vapor phase inflows via the vapor pipe, and through which the working fluid changed in phase from the vapor phase to the liquid phase flow out to the liquid pipe. The phase change flow channel has a reduced diameter part having a flow channel cross-sectional area decreasing in a direction from upstream toward downstream of the working fluid.
