Patent ID: 7137443

Claim:
A method for making a capillary structure on an inside surface of a container, comprising the steps of: (a) providing a slurry of metal particles that are mixed with a brazing compound wherein said metal particles comprise a first melting temperature and said brazing compound comprises a second melting temperature that is lower than said first melting temperature; (b) mixing two drops of an organic liquid binder with said slurry of metal particles to create an adhesive quality on their surface; (c) coating at least portion of said inside surface of said container with said slurry; (d) drying said slurry to form a green wick; and (e) heating said green wick to a temperature that is no less than said second melting temperature and below said first melting temperature so that said brazing compound is drawn by capillary action toward adjacent of said metal particles so as to form heat-distribution fillets between said adjacent metal particles thereby to yield a brazed wick.
