Abstract:
There is described a boiler (1) including a burner (3), a heat exchanger (50) adapted to raise the temperature of a working fluid through heat exchange with an exchange fluid, including a plurality of heat exchanger modules (2) placed side by side in order to define a combustion chamber within which the burner (3) for the generation of exchange fluid is inserted, exchange walls (2C) for the passage of exchange fluid, an expulsion chamber (2D) for the exchange fluid fitted with a discharge flue (4) and a substantially parallelepiped casing (5) adapted to be filled with working fluid. The boiler includes side walls (5D) inter-connected by stay-plates (6) placed between the heat exchanger modules (2) and top and bottom walls (5B) and end walls (5C) fitted with reinforcing elements (8) which prevent their deformation due to the pressure of working fluid.

Abstract:
A heat exchanger (10) is manufactured from a single piece of heat-conducting material and comprises fins (20) for guiding a fluid and for transferring heat between the fluid and the heat exchanger, wherein between the fins are provided transverse fins (24) which extend in a direction substantially transversely of the fins over a distance which is less than the distance between the fins and in a direction substantially transversely of the flow direction of the fluid, wherein the transverse fins are arranged alternately close to or on mutually adjacent fins in order to cause a fluid flowing between the fins to follow a meandering path between the fins, wherein the lateral direction lies substantially perpendicularly of the fins.
Abstract:
A heat exchanger card (10) is made of a heat conductive material and is provided with an integral meandering conduit (12). The conduit (12) has an inlet (14) and an outlet (16) which each open at edge (18) of the card (10). Slots (20 and 22) are cut in the card (10) to form gaps (24 and 26) respectively which divide the card (10) into national sections (28, 30 and 32). The slots (20 and 22) extend between lengths of the conduit (12) which pass each other.
