Abstract

On décrit un caloduc qui peut être posé horizontalement, un procédé de fabrication du caloduc et un procédé qui permet d'utiliser efficacement ce dernier, tel que par exemple un procédé permettant de désinfecter des sols à un faible coût. Un tuyau d'alimentation (2) en chaleur est inséré dans une conduite à vide (1) remplie d'un fluide (F) de milieu chauffant de manière à se trouver adjacent à une surface périphérique interne de la conduite à vide (1) pour constituer un caloduc (A). Le caloduc (A) est placé horizontalement dans le sol, dans une serre agricole, dans un bac de culture, dans le sol d'une maison ou sous la terre de manière à ce que le tuyau d'alimentation (2) en chaleur soit placé sur un côté inférieur de la conduite à vide (1). Ainsi ledit caloduc est utile pour effectuer la désinfection du sol par la chaleur ou pour chauffer des serres agricoles, pour chauffer la terre dans des bacs de culture, pour chauffer le sol d'une maison et pour faire fondre la neige.
