Enhanced heat transfer structure with heat transfer members of variable density

A method for transferring heat from a localized heat source, comprising the steps of:

• attaching at least one localized heat source at a predetermined location on a first wall of a heat transfer module, said heat transfer module further having a second wall thereof secured to said first wall and forming a duct chamber therebetween;
• installing a plurality of heat transfer members in said duct chamber having a variable density concentration, positioning said heat transfer members with the density concentration thereof increased in the direction of a flow of a coolant media in said duct chamber, and aligning one of said heat transfer members with greatest density concentration with said predetermined location of said at least one localized heat source;
• installing flow restriction members in said duct chamber to increase velocity of a coolant media flow adjacent said predetermined location and to at least partially block said coolant media flow around said at least one localized heat source;
• and
• supplying the coolant media into said heat transfer module.
