FIELD: machine building. ^ SUBSTANCE: utilising water heater (UWH) is made with packages of heat exchanging tube panels wherein flat pipes are bent along Archimedean spiral, while in adjacent panels spiral tubes are oppositely twisted. Distance between panels is equal to external diametre of tubes. The panels have a shape of a truncated cone, smaller base of which is below a bigger base. The tubes are embedded in a ferrule of a water collector positioned in the central part of the UWH along its lengthwise axis. In an internal cavity of the collector there are made lengthwise and cross partitions dividing this cavity into a row of water chambers facilitating multi-path motion of water in this circuit of the UWH. ^ EFFECT: increased reliability and compactness of utilising water heaters at their operation, when non-combustible particles of lubricant are found in composition of exhaust gases of diesel. ^ 7 cl, 4 dwg |
