Heat storage unit
A heat storage unit, at least comprises one single-layer closed case (2) that has at least one heat exchange surface (8, 9) and a non-heat exchange surface; the internal space of the closed housing (2) is filled with a foam skeleton (4); the phase change medium (6) is homogeneous distributed in the voids of the foam skeleton (4), and forms a composite material (02) together with the foam skeleton (4), the composite material has a higher thermal conductivity coefficient than that of the pure phase transition medium (6); vibration particles (3) are made of shape memory alloy, pressed into strips and then filled into the voids of the foam copper frame (4) by filtration; the ultrasonic generator (05) emits ultrasonic to induce the vibration particles (3) to generate vibration, the vibration converts the liquid phase transition medium (6) from natural convection or pure heat conduction to forced convection.
