Abstract
A valve unit and an apparatus having the same include a plug which includes a phase change material in a solid state at a room temperature and a plurality of fine heat-dissipating particles dispersed in the phase change material. The fine heat-dissipating particles dispersed in the phase change material dissipate heat by absorbing an electromagnetic wave energy generated by electromagnetic wave radiation from the outside and block fluid flow in a path formed by a channel. As an external energy source irradiates an electromagnetic wave on the plug, the plurality of fine heat-dissipating particles dissipate heat and the phase change material becomes molten, thus opening the path to allow the fluid to flow.
