Phase　change　cold　energy　storage　devices　(PCCESDs)　that　use　thermoelectric　coolers　(TEC)　as　cooling　sources　have　promising　application　prospects　for　alleviating　the　mismatch　between　energy　supply　and　demand.　Here,　a　new　type　of　PCCESD　based　on　flat　miniature　heat　pipe　arrays　(FMHPAs)　was　designed.　The　device　utilized　a　TEC　as　the　cooling　source　and　10#　paraffin　wax　as　the　phase　change　cold　energy　storage　material.　The　effects　of　the　operating　voltage　and　flow　rate　of　the　chilled　water　of　TEC　and　the　different　flow　rates　and　temperatures　of　heat　transfer　air　(HTA)　were　analyzed.　The　results　indicated　that　the　addition　of　FMHPA　could　effectively　enhance　the　performance　of　the　device.　Under　the　experimental　conditions　of　this　study,　when　the　chilled　water　flow　rate　was　fixed　at　1　m3/h,　the　cooling　power　of　the　TEC　peaked　at　14.94　W　as　the　operating　voltage　increased　to　6　V;　then,　the　cooling　power　tapered　off.　The　cooling　power　of　the　TEC　reached　15.97　W　at　an　operating　voltage　of　7　V　and　a　chilled　water　flow　rate　of　1.5　m3/h.　Under　this　condition,　the　charging　process　was　completed　in　the　shortest　time　(134　min).　Additionally,　when　the　flow　rate　and　temperature　of　the　HTA　were　2　m/s　and　33　degrees　C,　respectively,　the　discharging　process　was　completed　first　(62　min).
