The present invention relates to a kind of integrated heat pipe and a method of heat exchange. The heat pipe includs a tank(1-2) as a heating potion and a lot of heat carriers(1-4) as a radiating portion. The tank(1-2) and the heat carriers(1-4) have same cavity in which a coolant(1-3) is partially filled. The tank(1-2) is held in close contact with a heat source(such as electronic elements). The heat carriers(1-4) are arranged at an interval so that radiating channls(1-4a) are formed between them. The coolant(1-3) in the tank(1-2) is heated by the heat source, voporized coolant moves to the heat carriers(1-4) and condenses in there. According to the invention, the heat pipe can be increased its radiating surface signaficantly with the varied arrangement of the heat carriers(1-4).

L'invention concerne un caloduc intégré et un procédé d'échange de chaleur. Ce caloduc comprend un réservoir (1-2), servant de partie chauffante et une pluralité de supports thermiques (1-4) servant de partie radiante. Le réservoir (1-2) et les supports thermiques (1-4) présentent une cavité commune remplie partiellement d'un caloporteur (1-3). Le réservoir (1-2) est maintenu en contact étroit avec une source de chaleur (par exemple avec des éléments électroniques). Les supports thermiques (1-4) sont espacés de manière à permettre la formation de canaux radiants (1-4a) entre eux. Le caloporteur (1-3) se trouvant dans le réservoir (1-2) est chauffé par la source de chaleur. Une fois à l'état de vapeur, il est dirigé vers les supports thermiques (1-4) où il se condense. Selon l'invention, on peut agrandir la surface radiante de ce caloduc de manière importante en faisant varier la disposition des supports thermiques (1-4).
