BRAZED WICK FOR A HEAT TRANSFER DEVICE AND METHOD OF MAKING SAME

摘要

A capillary structure (25) for a heat transfer device (2), such as a heat pipe (2) is provided having a plurality of particles (27) joined together by a brazing compound (30) such that fillets (33) of the brazing compound (30) are formed between adjacent ones of the plurality of particles (27). In this way, a network of capillary passageways are formed between the particles (27) to aid in the transfer of working fluid by capillary action, while the plurality of fillets (33) provide enhanced thermal transfer properties between the plurality of particles (27) so as to greatly improve over all heat transfer efficiency of the device (2). A method of making the capillary structure (25) according to the invention is also presented.
