Abstract

L'invention concerne un échangeur de chaleur et un dispositif de production d’eau chaude l’utilisant, capables d’empêcher efficacement l’accumulation de tartre d’entraver la circulation, sans que toutes leurs canalisations extérieures, ou à défaut seulement celles situées du côté aval, soient formées de canalisations de gros diamètre. Comme il est possible de maintenir une plus importante section droite de circulation entre une première canalisation extérieure (53) et diverses premières canalisations intérieures (51) qu’entre une deuxième canalisation extérieure (54) et diverses deuxièmes canalisations intérieures (52) en faisant en sorte que le nombre de premières canalisations intérieures (51) constituant le côté aval du dispositif de production d’eau chaude inférieur au nombre de deuxièmes canalisations intérieures (52) constituant le côté amont, il est possible d’empêcher efficacement le tartre d’entraver la circulation dans la canalisation extérieure (53) du côté aval, sans canalisations extérieures (53, 54), ou à défaut avec uniquement les canalisations extérieures (53) situées du côté aval, formées de canalisations de gros diamètre. Dans le cas présent, l’eau destinée à la production d’eau chaude peut être suffisamment chauffée par les diverses deuxièmes canalisations intérieures (52), car il existe un plus grand nombre de deuxièmes canalisations intérieures (52) du côté amont du dispositif de production d’eau chaude qu’il n’existe de premières canalisations intérieures (51) du côté aval.
