A heat pipe type circular radiator includes a plurality of sector cooling fins and a heat pipe. Each of the sector cooling fins has a main fin member with a through hole and has a big sector folded side and a small sector folded side at two lateral sides of the main fin member, respectively. The heat pipe passes through the sector cooling fins via the through hole respectively. Because the folded sides are designed has a shape of sector, the heat pipe with the cooling fins can be bent circularly and attached with a cooling base to form the circular radiator.
