Embodiment Construction

[0054] The heat exchanger 1 shown in the figure comprises a shell or shell 10 defining a closed space, inside which a double tubular tube bundle 2 is fixedly mounted, the double tubular tube bundle 2 consisting of two bundles of coaxial tubes arranged end to end, One of them acts as the primary heat exchanger for the primary tube bundle 2a and the other acts as a secondary heat exchanger for the secondary tube bundle 2b.

[0055] The enclosed space is approximately cylindrical in shape with a horizontal axis X-X'.

[0056] exist figure 1 and figure 2 In the embodiment shown in , the primary bundle 2a consists of a set of five adjoining tubes forming a helically wound member with axis XX', while the other secondary bundle 2b consists of the same helically wound with axis XX' composed of two adjacent tubes.

[0057] The five tubes forming the primary bundle 2a and the two tubes forming the secondary bundle 2b are identical, having the same length and the same diameter. Ther...

Abstract

The invention relates to a device that includes means for conveying or producing hot gases and a condensing heat exchanger including: an bundle of helical tubes serving as primary exchanger, mounted within a gas-impermeable housing and equipped with a gas discharge trunk, means for circulating a primary fluid in the primary exchanger, two deflector plates and a deflecting ring arranged so as to circulate the hot gasses through the coils of the primary exchanger. Said device is characterized in that it includes a second tube bundle serving as a secondary exchanger, means for circulating therein a secondary fluid separate from the primary fluid and in that the second deflector plate is inserted between the primary exchanger and the secondary exchanger. The invention can be used in the production of heating water and of hot water for sanitation.

Description

technical field [0001] The invention relates to a plant for the production of hot fluids, comprising in particular a condensing heat exchanger for heating several fluids and means for the production of hot gases or for the introduction of hot gases previously produced by an external source Components for producing hot gases are for example burners, in particular gas burners or oil burners. [0002] The device is especially intended to equip gas boilers for domestic or industrial applications, for example with a view to feeding central heating circuits and / or supplying water to sanitary facilities. Background technique [0003] The heat exchanger of the device is of the type comprising an enclosure delimiting a closed space inside which is accommodated at least one bundle of tubes such as described in document EP-B-0 678 186, which can be modified if necessary quote. [0004] In document EP-B-0 678 186 a heat exchanger element is described which consists of tubes of a mater...
