Probe type die cooling arrangement
Abstract
Abstract A cooling arrangement for cooling, with liquid carbon dioxide or the like, a die formed with a coolant receiving passage in which a probe structure is mounted in the passage in sealed relation thereto adjacent the outer end of the passage, with the probe comprising an elongate tubular member formed at one end to receive the coolant fluid and at the other end to discharge the fluid into the die passage, and an annular heated coolant receiving chamber formed about the tubular member adjacent its outer end and formed with a heated coolant discharge port adjacent the outer end of the passage and a heated coolant receiving port adjacent the other end thereof and short of the inner end of the tubular member. The coolant receiving end of the tubular member and the coolant discharge end of the chamber are connected into a closed circuit refrigeration system for supplying liquified gas to the probe and reliquifying the heated gas after it leaves the probe for resupply to the probe.
