Abstract: A fluid pressurizing structure and fan using same are disclosed. The fluid pressurizing structure includes a hub having a plate portion located therearound. The plate portion has a first and a second surface provided with a plurality of first and second hollow protrusions, respectively. Each of the first hollow protrusions has a first fluid inlet and a first fluid outlet, and each of the second hollow protrusions has a second fluid inlet and a second fluid outlet.
