Abstract
(DE)
Es wird ein Durchlauferhitzer zum Erhitzen einer durchströmenden Flüssigkeit vorgeschlagen, der einen sich symmetrisch entlang einer Längsachse erstreckenden Innenkörper, der eine Heizung aufweist, und einen den Innenkörper umgebenden Außenhülle aufweist, wobei zwischen Innenkörper und Außenhülle ein wendelförmig um den Innenkörper umlaufender und von der Außenhülle begrenzter Strömungskanal für die durchströmende Flüssigkeit ausgebildet ist. Der Durchlauferhitzer ist dadurch gekennzeichnet, dass die Außenhülle aus wenigstens zwei in Richtung der Längsachse teilbaren Segmentschalen zusammengesetzt ist.
(EN)
The invention relates to an instantaneous water heater for heating a flowing liquid. Said instantaneous water heater comprises an inner body extending symmetrically along a longitudinal axis and which comprises a heating device, and an outer sleeve surrounding the inner body. A spiral-shaped flow channel for the flowing liquid, surrounding the inner body and defining the outer sleeve, is formed between the inner body and the outer sleeve. The instantaneous water heater is characterised in that the outer sleeve is made of at least two segment sections that can be divided in the direction of the longitudinal axis.
(FR)
L'invention concerne un chauffe-eau instantané destiné à chauffer un liquide en écoulement. Le chauffe-eau comprend un corps intérieur qui s'étend de manière symétrique le long d'un axe longitudinal et qui présente un dispositif de chauffage, et une enveloppe extérieure entourant le corps intérieur. Un canal d'écoulement pour le liquide en écoulement, faisant le tour du corps intérieur de manière hélicoïdale et délimité par l'enveloppe extérieure, est formé entre le corps intérieur et l'enveloppe extérieure. Le chauffe-eau instantané est caractérisé en ce que l'enveloppe extérieure est composée d'au moins deux coques segmentées pouvant être divisées en direction de l'axe longitudinal.
