A heat transferring device having an adiabatic unit is provided. The heat transferring device includes a lower plate including an evaporator which contacts a heating element and allows a liquid refrigerant to absorb heat transferred from the heating element to thus evaporate, a condenser in which gas flowing from the evaporator is condensed, a gas passage through which the gas flowing from the evaporator into condenser, a liquid refrigerant passage through which the liquid refrigerant flows from the condenser into the evaporator and which includes a portion used as a channel region bordering the evaporator, and an adiabatic unit provided between the liquid refrigerant passage and the gas passage so that elements hindering the flow of the liquid refrigerant can be prevented from being introduced from the gas passage into the liquid refrigerant passage; and an upper plate which contacts some members of the lower plate including the adiabatic unit.

A flat evaporator is provided. In the evaporator, a common chamber formed on a substrate with a predetermined diameter and depth for containing a coolant is divided into a vaporization cavity region, a capillary region surrounding the vaporization cavity region, and a manifold region surrounding the capillary region. The capillary region has a capillarity generator capable of generating capillary action, and a top plate is configured to include an exhaust unit including a gas collector to exhaust a gas coolant generated in the vaporization cavity region. The evaporator can be implemented as a small and thin cooling device for performing cooling without external power. Furthermore, the evaporator can effectively prevent degradation of fluid flow force due to coexistence of gas and liquid by isolating a liquid coolant from a vaporized coolant by a capillary region, thereby significantly improving heat exchange characteristics.
