[0001] The object of the present invention is a fin plates heat exchanger, the most beneficial
used in the condensation gas furnaces, as a heat exchanger with closed combustion
chamber.
[0002] In the state of the art engineering, were known exchanger's solutions joining, in
one construction, functions of primary heat exchanger and economizer.
[0003] The example of such solution is design of the German Viessman Company exchanger of
plate construction, where two agents flow through the exchanger in parallel layers,
divided by corrugated walls.
[0004] The second example could be the tube exchangers produced by Buderus Company. Tubes
have enlarged heat exchange surface by application of the fins. In that solution,
each tube with its fins is a separate element. Those tubes are joined in the separate
process, creating the heat exchanger.
[0005] The essence of the solution according to the present invention is design of the fin
plates heat exchanger in which internal edges of the fin plates define the space of
heat exchanger combustion chamber. Formed in the fin plates neck holes create, after
tight joining, flow channels of heated liquid agent and create the spaces between
individual fin plates, of gas flow of heating agent, created in the combustion chamber.
[0006] In the solution according to the present invention, the design of the fin plates
heat exchanger provide obtaining of the high heat exchange surface to the mass ratio
and also highly profitable working parameters and high thermal efficiency.
[0007] The fin plates heat exchanger according to the present invention is characterized
by simplified manufacturing technology with possibility of full automation of production
process. Additionally it has a simple, light and compact design and ergonomic ratings,
visible especially during conducting of montage and maintenance operations.
[0008] In the exchanger according to the present invention taking place the full integration
of the combustion chamber with heat exchange surface. The important advantage is the
low exhaust and liquid agent flow resistances. Heat exchange developed surface creates
possibility of combustion products condensation, which increase the heat efficiency
of the exchanger and its service life.
[0009] The subject of the present invention is presented on an execution example, on the
enclosed figure on which fig. 1 presents the head view of fin plate, fig.2 presents
the side view of the fin plate, fig.3 - the axonometric view of lower part of the
heat exchanger packet.
[0010] The fin plates heat exchanger according to the present invention is made of the fin
plates
1, creating after joining the heat exchanger packet. Internal edges of the fin plates
1 define the heat exchanger combustion chamber space. Formed in the fin plates
1, the neck holes
3, after tight joining creates flow channels
4 of heated liquid agent and simultaneously creates the spaces
5, between individual fin plates
1, of flow of gaseous heating medium arising in the combustion chamber
2.
1. Fin plates heat exchanger made of fin plates creating the heat exchanger packet, being
integrated heat exchange surface, characterised in that the internal edges of the fin plates define the combustion chamber (2) of exchanger,
and formed in the fin plates (1) neck holes (3), creates after tight joining flow
channels (4) of heated liquid agent and creates flow spaces (5) between individual
fin plates (1) of gaseous heating agent arising in the combustion chamber (2).
