PURPOSE: A blower used in a refrigerator van is provided to improve cooling efficiency by blowing air through simultaneously rotating two dual centrifugal fans using one motor. CONSTITUTION: A blower includes a pair of scroll cases(100) formed at both sides thereof with an air suction hole(140). An air exhaust hole(130) is formed at the front of the scroll cases(100). A pair of dual centrifugal fans(200) is rotatably installed in each scroll case(100). The center of the dual centrifugal fan(200) is divided by a hub plate. A driving motor(300) is positioned between the scroll cases(100) so as to simultaneously rotate the pair of dual centrifugal fans(200). A supporting plate(400) is provided to support the driving motor(300) and the scroll cases(100). The supporting plate(400) is formed with a pair of air guiding holes(410).
