Cool Core Heat-pipes

CRS Cool Core Heat-pipes are used in moulding tool core pins to rapidly transport heat from the tip of the core pin back to the cooled tooling plates. Even when moulding engineering grade plastics, the Heat-pipe temperature rarely exceeds 100° C, the largest temperature gradients occuring through the soldifying plastic and wall of the steel core pin. The Heat-pipe is inserted into the core (drill size = Heat-pipe diameter) using CRS Coolflex 90 thermal compound to ensure a good thermal joint. Ideally, cooling water is passed over the exposed end which should be 50% the length of the length which is being heated at the core pin end. When using the Heat-pipes to disipate heat directly to the cooling water, it is preferable that the water flow be of a high velocity rather than of a high volumetric flow -rate.
