Title:
PHASE-CHANGE MECHANICALLY DEFORMABLE COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/225844
Kind Code:
A1
Abstract:
The present invention comprises: a base provided so as to receive heat from a heat source; a hollow cylinder-shaped fixed cylinder fixedly provided so as to receive the heat from the base, and provided such that an opening thereof is closed by means of the base; fixed fins fixedly provided at the fixed cylinder so as to receive the heat from the fixed cylinder; a piston blocking, in a watertight or airtight manner, the inside of the fixed cylinder in the direction vertical with respect to an axial direction, and fitted to be slidable in the axial direction so as to form an accommodation chamber for accommodating a phase change material; and an elastic member for applying an elastic restoring force toward the base with respect to the piston, wherein, when the heat from the heat source is low temperature, the phase change material changes phase in the direction in which the volume thereof is reduced, and the piston is returned to a backward position at the base side by means of the elastic restoring force of the elastic member and, when the heat from the heat source is high temperature, the phase change material changes phase in the direction in which the volume thereof is increased, and the piston is operated so as to move from the backward position to a forward position at the opposite side of the base against the elastic restoring force of the elastic member.
