Abstract: A support structure of heat dissipation unit is applicable in a heat dissipation unit. Two sides of the heat dissipation unit are respectively formed with a condensation side and an evaporation side. Two ends of the support structure respectively abut against and connect with the condensation side and the evaporation side. The support structure includes a base section and a thorny section. The base section has a contact face and a support face. The thorny section is composed of multiple thorny columns arranged on the support face of the base section in an array. The thorny columns are arranged at intervals, whereby a passage is defined between each two adjacent thorny columns. The support structure with the thorny section serves to speed vapor-liquid circulation in the heat dissipation unit and increase flowing speed of the working fluid so as to greatly enhance heat dissipation performance.
