Definitions
- the invention is based on a gas-heated water heater according to the preamble of the main claim.
- a known water heater of this type both end lamella parts of an end lamella are provided on the upstream side with an angled edge strip and are firmly connected to one another by welding.
- a sufficiently dimensioned space must be provided between the end fins and the adjacent water chambers so that the edges of the base parts and cover parts of the water chambers to be soldered or welded remain easily accessible by the soldering or welding device and by the angled edge strips of the end fins not be covered. This increased space requires a broadening of the heat exchanger, which affects the
- the arrangement according to the invention with the characterizing features of the main claim has the advantage that the two Parts of a water chamber, connection and deflection chamber can be connected to each other without hindrance by the angled edge strips of the end lamellae, so that the water chambers move closer to the end lamellae and as a result the heat exchanger can be made shorter overall with the same output than in the known devices of the generic type.
- the second end lamella part is simply pushed onto the first end lamella part from below until the latching means engage and connect the two end lamella parts with the necessary strength.
- the end plates according to the invention are also more elastic due to the locking connection of their two parts than the known end plates with welded plate parts, so that the forces exerted by the end plates designed according to the invention on the water chambers due to different thermal expansions are lower than the forces exerted by the end plates of the known type.
- the latching means for connecting the first and second endiamella part between the passages or recesses for the water pipes are provided on the two end lamella parts, the latching means can be dimensioned sufficiently large without additional space requirement for proper functioning.
- the second end lamella part is provided with tabs which reach between the water pipes and cover the slots on the first end lamella part, from which locking tabs are brought out, which are located behind locking shoulders on the first end lamella part grip, which are formed on the edge edges of the tabs of the first end lamella part leading without play.
- the end lamellae of which are provided on the outflow side with an edge leg emerging from the lamella plane, which serves as a support or guide for flow protection or the like, it is proposed that the upper edge leg be formed on a third end lamella part, which is also only formed by Locking means is connected to the first end plate part.
- edge leg of an end lamella provided on the outflow side does not hinder the production of the adjacent water chamber and, moreover, does not adversely affect the thermal expansion capacity or the "softness" of the end lamella.
- FIG. 1 shows a partial area of a heat exchanger and a connecting shaft of a gas-heated water heater, partly in side view and partly in section
- FIG. 2 shows a section of a first end lamella part of the heat exchanger according to FIG. 1 in side view
- FIGS. 3 and 4 show sections along lines III-III and IV-IV in Figure 2
- Figures 5 and 6 sections of a second and a third end lamella part in side view
- a water heater has a combustion shaft 10, on which a heat exchanger, designated as a whole with reference number 12, is placed and held in place by means not visible in the drawing.
- the heat exchanger 12 has a lamella block consisting of individual fins 14, through which a plurality of water tubes 16 arranged parallel to one another are passed.
- the individual fins 14 can consist of copper or stainless steel and are between the through Were provided for the water pipes 16 with pleats to increase the thermal expansion or "softness".
- the water pipes 16 open out on both sides in water chambers 18, which are each formed from a base part 20 and a cover part 22.
- the two parts 20, 22 are connected to one another at their flat edges 20a, 22a by soldering or welding.
- the heat exchanger 12 is provided with end fins 24 which are made of stainless steel and are composed of three individual parts as described in more detail below, which are provided at the bottom with an edge strip 26 angled from the lamella plane and at the top with an obliquely angled edge leg 28. With the edge strip 26, the heat exchanger 12 is centered on the combustion shaft 10.
- the edge leg 28 forms a guide and a support for a flow safety device, which can be pushed onto the heat exchanger 12 from the front.
- the end fins 24 have in addition to these load-bearing and centering functions to seal the path of the combustion gases to the sides and must also be designed so that they do not exert unacceptably high thermal expansion forces on the adjacent water chambers 18 despite the required mechanical strength.
- Each end lamella 24 consists of a first end lamella part 30 (FIG. 2) which is provided with openings 34 for the water pipes 16 which are surrounded by collars 32 and is welded to them.
- the end lamella part 30 is also between the openings 34 Provided from the lower edge 36 slots 38, which result in the required "softness" of the end lamella 24.
- two tabs 40 are protruded from the end lamella part 30, which lie opposite one another in pairs and form an insertion channel 42 between them and the adjacent, undeformed lamella areas.
- further insertion channels 44 are provided in the upper region of the end lamella part 30, which are formed by webs 46 made out of the flat lamella material.
- the first end lamella part 30 is completely flat, so that after completion of the entire end lamella parts 30 with extensive lamella blocks, the parts 20, 22 forming the water chambers 16 can be soldered or welded to one another without hindrance.
- the lower edge strip 26 of an end lamella 24 is formed on a second end lamella part 50 (FIG. 5) which is provided with cutouts 52 open at the top for the water pipes 16. Between the cutouts 52, alternately and at the same pitch as the slots 38 on the first end lamella part 30, narrower tabs 54 and wider tabs 56 are formed. From the narrower tabs 54 downward facing latching tongues 58 are highlighted. The tabs 54 are dimensioned such that they can be inserted in a suitable manner into the insertion channels 42 of the first end lamella part 30.
- the second end lamella parts 50 are simply pushed onto the first end lamella parts 30 from below in such a way that the tabs 54 enter the insertion channels 42 and the tabs 58 finally engage behind the upper edge edges 59 of the tabs 40. Then the second lamella parts 50 are firmly attached to the first end lamella parts 30, the tabs 54 and 56 covering their slots 38 from the inside except for a short upper area in the manner of a labyrinth seal.
- the upper edge leg 28 of an end plate 24 is formed on a third end plate part 60 (FIG. 6).
- this is provided with recesses 62 which are open at the bottom for the water pipe 16 and with tabs 64, 66.
- the narrower tabs 64 have tongues 68 pointing upward and are dimensioned such that they can be inserted in a suitable manner into the insertion channels 44 of the first lamella part 30.
- the third end lamella parts 60 are simply pushed onto the first end lamella parts 30 from above such that the tabs 64 enter the insertion channels 44 and the tongues 68 finally engage behind the lower edge edges 69 of the webs 46. Thereafter, the third end lamella parts 60 are also firmly attached to the first end lamella parts 30, the tabs 64, 66 covering the upper regions of the slots 38 from the outside in the manner of a labyrinth seal.
