The invention discloses a phase-change
energy storage perforated plate and a preparation method. The phase-change
energy storage perforated plate consists of a phase-change unit, a core plate and a
surface plate, wherein the phase-change unit is made of a ternary
fatty acid eutectic mixture / expanded
graphite composite phase-change energy-
storage material; the core plate is of an aluminum perforated structure; the
surface plate is a medium-density
fiber plate or a real-wood
single plate; pores of the perforated plate are filled with the phase-change unit; an
epoxy resin is adopted as an
adhesive; and the perforated plate is prepared in a cold pressing mode. Due to adoption of a ternary
fatty acid eutectic mixture, the defects that a single organic phase-change material is low in heat
conductivity, low in
latent heat, improper in phase-
change temperature, easy to leak off and the like, are overcome; by adopting the phase-change
energy storage perforated plate prepared by using the method, key problems that a conventional phase-change energy
storage material generally has seepage, is low in
utilization rate, low in durability, and the like, can be solved; the heat storage time of thecomposite material is shortened by 58.3% and the heat
release time is shortened by 56.1% when being compared with those of the ternary
fatty acid eutectic mixture; and the phase-change energy storageperforated plate is stable in
mechanical property, the
static bending intensity of the perforated plate is 11.6-13.8 MPa, the elastic modus of the perforated plate is 2.3-2.6 MPa, the internal bondingstrength of the perforated plate is 0.32-0.43 MPa, and the heat
release time of the phase-change energy storage perforated plate is prolonged by 70-85% when being compared with that of a common perforated plate.
