The CTRC is a graduated National Science Foundation Industry/University Cooperative Research Center, and addresses pre-competitive, longer-term research and development issues in the area of high-performance heat removal from compact spaces. The agenda for the Center is set on a yearly basis with research projects identified through a ranking by all members. Regular updates on the work are made available to members through a restricted-access web page. The Center meets twice a year to review progress and choose upcoming projects.

One of the distinctive features of CTRC is that the research agenda is set by the members—each member has a strong input in the research directions adopted. Since members are from diverse industries, beneficial cross-industry interactions are common. A product-oriented focus is maintained. Equipment manufacturers are included amongst the participants, and this facilitates a translation of research ideas and prototypes into products.
