A COOLING CHANNEL SYSTEM WITH A SURFACE CONTACT PORTION

摘要

PURPOSE: A cooling channel for conveniently forming the cooling channel of a three dimensional form is provided to reduce a manufacturing time comparing with a cooling channel using a laminate fabrication method. CONSTITUTION: A cooling channel for conveniently forming the cooling channel of a three dimensional form includes a channel-forming space unit(3), a cooling water inlet unit(5), a cooling water outlet unit, and a channel wall unit(7). The channel-forming space unit is formed in the lower part of the opposing part. The cooling water inlet unit is formed in one or more inlet port. The channel wall unit is parallel formed from the cooling water inlet portion along the cooling water outlet unit.
