Title (EN) HEAT EXCHANGER FOR HEATING WATER
(FR) ÉCHANGEUR DE CHALEUR DE CHAUFFAGE D'EAU
Abstract:
(EN) Aspects of the invention provide a heat exchanger that includes a shell coupled to a top tube sheet and a bottom tube sheet. The shell at least partially defines an interior region. The heat exchanger also includes a burner positioned to deliver combustion gases into the interior region. A plurality of tubes, configured to circulate a fluid therein, extend through the interior region around the burner. The heat exchanger further includes a divider that extends within the interior region from the top tube sheet to the bottom tube sheet and between one of the plurality of tubes and another non-adjacent tube of the plurality of tubes. The divider and the plurality of tubes define a receiving section of the interior region for receiving combustion gases from the burner and an exhaust section of the interior region in fluid communication with a combustion gas vent.
(FR) L'invention concerne, selon certains aspects, un échangeur de chaleur comprenant une coque accouplée à une plaque tubulaire supérieure et à une plaque tubulaire inférieure. La coque définit, au moins partiellement, une région intérieure. L'échangeur de chaleur comprend également un brûleur placé de manière à distribuer des gaz de combustion dans la région intérieure. Une pluralité de tubes, conçus pour faire circuler un fluide à leur intérieur, s'étendent à travers la région intérieure autour du brûleur. L'échangeur de chaleur comprend en outre un séparateur s'étendant à l'intérieur de la région intérieure, de la plaque tubulaire supérieure à la plaque tubulaire inférieure, et entre un tube parmi la pluralité de tubes et un autre tube non adjacent parmi la pluralité de tubes. Le séparateur et la pluralité de tubes délimitent une section de réception de la région intérieure destinée à recevoir des gaz de combustion en provenance du brûleur et une section d'échappement de la région intérieure en communication fluidique avec un évent des gaz de combustion.
