Abstract

A heating device (1) comprises a burner (2) and a heat exchanger (3). In one part (4) the heat exchanger (3) is fed hot combustion gases which flow downwards in a meandering fashion through a system, connected by means of a wall (9), composed of parallel gills (lamellae) (8, 8', 8'',...) and horizontal guide (baffle) walls (11, 11', 11'',...) and heat up the wall (9) and, in a part (5) of the heat exchanger (3) adjoining the wall (9) produce an upwardly directed counterflow of a heat transporting medium through a system composed of parallel ribs (12, 12' 12'',...) which are provided with obliquely extending guide walls (13, 13', 13'',...). The parts (4, 5) which guide the combustion gas and the heat transporting medium are produced, as is the common boundary wall (9), by extrusion from aluminium in one piece or in segments which can be assembled. <IMAGE>

VERWARMINGSTOESTELHEATER

De uitvinding betreft een verwarmingstoestel zoals omschreven is in de aanhef van conclusie 1. De vervaardiging van een dergelijk verwarmingstoestel vergt met name voor het vervaardigen van de warmtewisselaar in de regel veel kosten 05 aangezien een groot aantal delen door lassen met elkaar bevestigd moet worden.The invention relates to a heating appliance as described in the preamble of claim 1. The manufacture of such a heating appliance generally requires a great deal of cost for the production of the heat exchanger, since a large number of parts have to be fastened together by welding.

De uitvinding beoogt dit bezwaar te ondervangen en nog verdere verbeteringen aan het verwarmingstoestel en met name de warmtewisselaar daarvan te verschaffen.The object of the invention is to overcome this drawback and to provide still further improvements to the heating appliance and in particular its heat exchanger.

10 Dit wordt volgens de uitvinding bereikt door middel van de maatregelen volgens het kenmerkende deel van conclusie 1.This is achieved according to the invention by means of the measures according to the characterizing part of claim 1.

Door het in één arbeidsgang vervaardigen van de warmtewisselaar wordt een aanzienlijke besparing van de pro-15 ductiekosten bereikt.By manufacturing the heat exchanger in one operation, a considerable saving of the production costs is achieved.

Bij voorkeur zijn tussen de extrusie lamellen losse verbindende geleidingsplaten aangebracht. Hierdoor wordt de gang van de hete gassen door de warmtewisselaar aanzienlijk verlengd hetgeen de warmteoverdracht naar het warmte-20 transportmedium voerende deel verbetert. Bij voorkeur verlopen de geleidingsplaten enigszins schuin naar beneden om eventueel condenswater af te voeren. De geleidingsplaten kunnen door lassen of dergelijke vast aangebracht worden of kunnen los worden ingelegd.Loose connecting guide plates are preferably arranged between the extrusion slats. As a result, the passage of the hot gases through the heat exchanger is considerably prolonged, which improves the heat transfer to the part carrying the heat transport medium. Preferably, the guide plates run down slightly at an angle to drain any condensation water. The guide plates can be fixed by welding or the like or can be inserted separately.

25 Het warmtetransportmedium voerende deel kan van langsribben zijn voorzien teneinde de warmteoverdracht naar het warmtetransportmedium te verbeteren. Het warmtetransportmedium voerende deel kan worden voorzien van dwars op de me-diumtransportrichting verlopende leischotten teneinde de weg-30 lengte van het mediumtransport door de warmtewisselaar te vergroten.The heat transporting medium carrying part may be provided with longitudinal ribs in order to improve the heat transfer to the heat transporting medium. The heat transporting medium carrying part can be provided with baffles running transversely to the medium transporting direction in order to increase the path length of the medium transporting through the heat exchanger.

De uitvinding wordt aan de hand van de figuren nader verduidelijkt.The invention is further elucidated with reference to the figures.

Figuur 1 is een doorsnede-aanzicht van een verwarmingstoestel volgens de uitvinding;Figure 1 is a cross-sectional view of a heating appliance according to the invention;

Figuur 2 is een doorsnede-aanzicht door het toestel 8702303 - < -2-uit figuur 1;Figure 2 is a cross-sectional view through the device 8702303 - <-2-of Figure 1;

Figuur 3 is een perspectivisch aanzicht van een alternatieve uitvoeringsvorm.Figure 3 is a perspective view of an alternative embodiment.

Het verwarmingstoestel 1 vertoont een brander 2, 05 een warmtewisselaar 3 bestaande uit een hete gassen voerend deel 4 en een warmtetransportmedium voerend deel 5. Op het toestel is een aanvoerleiding 7 voor het verwarmingsstelsel en een retourleiding 6 aangesloten. Het hete gassen voerende deel bestaat uit evenwijdige lamellen 8, 8', 8'*... die door 10 de wand 9 met elkander zijn verbonden, volgens de uitvinding zijn de wand 9 en de lamellen 8, 8', 8''... alsmede de be-grenzingswanden van het warmtetransportmedium voerende deel 5 als één geheel door extrusie uit aluminium vervaardigd of uit meerdere extrusiedelen samengesteld. Op de gebruikelijke wij-15 ze wordt door de brandstofleiding, bijv. gas 10 brandstof aangevoerd en in de brander 2 verbrand. De hete gassen bewegen daarna verticaal omlaag langs de lamellen 8, 8', 8''... en verwarmen daarbij de wand 9, die tevens een begrenzings-wand vormt van het warmtetransportmedium voerende deel 5.The heating appliance 1 has a burner 2, 05, a heat exchanger 3 consisting of a part carrying a hot gas 4 and a part transporting a heat transport medium 5. A supply line 7 for the heating system and a return line 6 are connected to the appliance. The hot gas-carrying part consists of parallel fins 8, 8 ', 8' * ... which are connected to each other by the wall 9, according to the invention the wall 9 and the fins are 8, 8 ', 8' '. .. as well as the boundary walls of the heat transport medium carrying part 5 as a whole made of aluminum by extrusion or composed of several extrusion parts. In the usual manner, fuel is supplied through the fuel line, e.g. gas 10, and burned in burner 2. The hot gases then move vertically downwards along the fins 8, 8 ', 8' '... and thereby heat the wall 9, which also forms a boundary wall of the part 5 carrying heat transfer medium.

20 Volgens het tegenstroomprincipe wordt het warmtetransportmedium in opwaartse richting door het deel 5 getransporteerd. Omdat de verbrandingsgassen neerwaarts stromen kan condensaat eenvoudig worden afgevoerd.According to the counter-flow principle, the heat transport medium is transported upwards through the part 5. Because the combustion gases flow downwards, condensate can be easily removed.

Volgens de uitvinding zijn voorts in het hete gas-25 sen voerende deel 3;horizontale geleidingsschotten 11, 11', 11''... aangebracht zodat de hete gassen een meandervormige weg door de warmtewisselaar moeten volgen. Dankzij deze maatregel is de weglengte voor de hete gassen aanzienlijk vergroot en wordt derhalve de warmteoverdracht verbeterd. Met 30 een overeenkomstig doel kunnen in het warmtetransportmedium voerende deel 5 verticaal verlopende evenwijdige ribben 12, 12', 12''... zijn aangebracht, welke eveneens voorzien kunnen zijn van enigszins hellende geleidingsschotten 13, 13', iqi i IJ · · · · 35 De verbrandingsgassen treden uit door een uitlaat 20 terwijl condens via een condensafvoer 21 wordt afgevoerd.According to the invention, horizontal guiding partitions 11, 11 ', 11' '... are also arranged in the hot gas-carrying part 3, so that the hot gases must follow a meandering path through the heat exchanger. Thanks to this measure, the path length for the hot gases is considerably increased and, therefore, the heat transfer is improved. For a corresponding purpose, vertically extending parallel ribs 12, 12 ', 12' '... can be arranged in the heat transport medium 5, which may also be provided with slightly inclined baffles 13, 13', iqi i IJ · · · The combustion gases exit through an outlet 20 while condensation is discharged through a condensation drain 21.

De constructie van deze warmtewisselaar is zowel op condenserende als niet-condenserende ketels van toepassing.The construction of this heat exchanger applies to both condensing and non-condensing boilers.
