The utility model discloses a stable fixed-load hot air circulating fan. The stable fixed-load hot air circulating fan comprises a supporting bottom plate, a driving motor, a centrifugal machine shell, a cooler, an impeller mechanism, a transmission shaft, an air inlet connecting channel, an air inlet conical channel, a heat insulation plate, a shock absorption supporting base and two inclined strut mechanisms. According to the stable fixed-load type hot air circulating fan, the damping compressed springs are installed between the damping supporting base and the supporting bottom plate to achieve the elastic supporting effect, so that the whole fan has the damping performance; the heat insulation cotton layer is filled in the heat insulation plate, so that the driving motor can be effectively protected; the cooler can be used for effectively controlling the temperature of the two bearings mounted on the rotating shaft, so that the bearings are prevented from being seriously abraded athigh temperature, and the
