This utility model relates to the field of sand cooling technology, specifically a vertical pipe sand cooling system using Freon refrigerant. It includes an installation plate with a cooling box fixedly mounted on it. Several sets of lower installation pipes are fixedly connected to the top of the cooling box, and several sets of cooling pipes are fixedly connected to the bottom of each lower installation pipe. A compressor is fixedly mounted on the top of the installation plate, and the compressor contains Freon refrigerant gas. By using Freon refrigerant circulation, combined with copper alloy cooling pipes that ensure full contact with the sand aggregate, the system solves the problem of low efficiency in traditional cold air cooling, significantly improving the cooling efficiency of the sand aggregate.
