Cooling Roller Product Brief

Current heat transfer cooling rollers are categorized by two inner structural forms: double-layer single-flow and double-layer dual-flow constructions. The internal circulating medium options are industrial water and thermal transfer oil. Significant differences exist between the two types in internal design and processing technology, generating large discrepancies in manufacturing expenses.

1. Inner Construction of Single-flow Expanded Heat Transfer Roller This cooling roller unit comprises outer housing, inner cylinder and spiral baffles attached to the inner cylinder. Cooling water or thermal oil flows through connecting tubes into the single internal circulation channel, traveling toward the opposite wall to absorb heat and realize stable cooling performance.

2. Inner Construction of Double-layer Dual-flow Heat Transfer Roller While equipped with outer shell, inner shell and spiral baffles like the single-flow roller, this variant adopts a special double-layer dual-flow circulation system matched with aluminum alloy circulation modules. Water and thermal oil pass through pipeline joints into dual heat exchange passages for two-way cycling. It achieves remarkable heat exchange efficiency, yet complicated manufacturing procedures result in relatively high overall costs.
