Annular air-cooled radiator for PVC (polyvinyl chloride) heat stabilizer

The utility model relates to the technical field of radiators, in particular to an annular air-cooled radiator of a PVC (polyvinyl chloride) heat stabilizer, which comprises a first radiator body and a second radiator body, first connecting pipes are connected to two ends of the top surface of the first radiator body, a first air inlet pipe is connected to the front end of the first radiator body, and a second air inlet pipe is connected to the rear end of the second radiator body. The two ends of the bottom face of the first radiator body are connected with first connecting pipes, the two ends of the bottom face of the second radiator body are connected with second connecting pipes, the front end of the second radiator body is connected with a second air inlet pipe, and densely-distributed air outlet holes are formed in the inner side of the first radiator body and the inner side of the second radiator body. Uniform air outlet can be formed, effective heat dissipation can be achieved through a single fan, th
