The utility model provides a coil stock cooling device, it includes unwinding mechanism, cooling body and winding mechanism. It convolutes on unwinding mechanism to treat the refrigerated coil stock. It convolutes on winding mechanism with realization cooling, cooling back coil stock through the cooling body under winding mechanism's drive to treat the refrigerated coil stock. In the basis the utility model discloses an among the coil stock cooling device, treat that winding mechanism was being transferred to to the refrigerated coil stock by unwinding mechanism in -process expandes, the interior process of cooling body is followed to the coil stock of expansion, and consequently, the cooling body can cool off the coil stock of expansion fast, improves cooling efficiency and refrigerated homogeneity.
