Abstract:
A method of manufacturing a heat pipe construction, comprising the steps of:providing an injection mold apparatus having a cavity; providing an input gate; providing a bleed off overflow gate in communication with said cavity; providing a tubular heat pipe charged with phase change media which is capable of being collapsed by imparting an external collapsing pressure; placing said tubular heat pipe into said cavity in said injection mold apparatus; introducing, via said input gate, a net shape moldable thermally conductive material into said cavity and around said tubular pipe; setting said bleed off overflow gate to open at a predetermined pressure which less than said external collapsing pressure; and relieving pressure in said cavity of said mold apparatus through said bleed off overflow gate when pressure in said bleed off overflow gate reaches said predetermined pressure.
