Vortex structure behind highly heated two cylinders with different heat flux in parallel arrangements has been studied experimentally. The surface temperature of the cylinders are set up to 600℃ while the Reynolds number based on the cylinder diameter is 250. The clearance of two cylinders plays a key parameter for the vortex interactions. For the vortex non-interacting regime, the Strouhal numbers (St) of both wake flows are almost same on equal heating condition. However, the Sts of both wakes are dividing with the increasing in the imbalanced cylinder heating. For the vortex interacting regime, the St of the heating side is not affect by the imbalanced heating. On the other hand, the St of non-heating cylinder is slightly increased with increasing the other cylinder heating.
