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. CRS-MST series +
