Typically, friction welding is used to produce pistons, however the resulting material build-up in the cooling channel
hinders controlled guidance of the cooling oil flow.
Experiments have shown that a laser diode stack can be operated without further cooling channel
optimisation at the same target temperature, with about 20 per cent higher output power,' reports Laufs.
This work proposes a new design of conformal cooling channel
, which mixing series and parallel pattern.
An appropriate design of cooling channel
reduces cooling time, increases the productivity, and minimizes undesired defects such as sink marks, differential shrinkage, thermal residual stress and warpage.
It consists of a carbon steel body, a sacrificial material layer, and an inclined cooling channel
. The carbon steel body is a place where discharged corium from the reactor vessel is rearranged and stabilized.
Advances in local heating and cooling include new induction heaters and zoning and wildly imaginative conformal cooling channel
shapes that are much more efficient than round channels.
A patented fluid flow path round the bushing dissipates heat and allows the process fluid to cool the bushing of the impeller from the outside, while still providing an internal spiral cooling channel
and is said to allow for dry running conditions.
It describes the transient, three-dimensional energy exchange processes in built-in motorized spindles--especially in a cooling sleeve with a single helical rectangular water- cooling channel
.  A similar approach is used by Institute of Machine Tools and Manufacturing (IWF), at ETH Zurich (the Swiss Federal Institute of Technology in Zurich).
The Gerlach equipment consists of an in-feed conveyor, preshock unit, shock channel with microwave support, hot air channel to uphold temperature until curing is reached, cooling channel
with air blow-off and caterpillar.
Water cooling reaches its limits where the space for cooling channel
bores is restricted.
Its diverting plug Z9675 enables the mould designer to intentionally design for a collision of this kind and thus optimise the position of the cooling channel
and the ejector.
