  • a trained heat exchanger is designed as a helically bent tube, which may be smooth or ribbed executed.
  • Corresponding partitions enclose the heat exchanger. These partitions are heated and generate depending on the design and location of the heater corresponding heat losses.
  • a heating device with a heat exchanger cartridge is known, one of a heat transfer fluid has flowed through channel and encloses an inner space, which has on at least one side an opening which is surrounded by an edge, which leads along the outer diameter of the heat exchanger cartridge.
  • a burner unit is arranged, which has a burner body arranged in the interior with a plurality of burner openings and a flange whose diameter exceeds the diameter of the edge of the heat exchanger cartridge and the end faces the heat exchanger cartridge and has a seat for a blower unit and with a fastening device by means of which Flange is connected to the heat exchanger cartridge to attach the burner unit to the heat exchanger cartridge.
  • the space enclosed by the coiled tubing interior is divided into at least two subspaces, with a support tube which extends through one of the subspaces and which supports the insulator from the side.
  • the burner unit which extends through the other subspace of the interior, thereby supporting the insulating body from the other side.
  • EP 1 255 086 A2 discloses a heat exchanger unit for a heating device, in which the heating channel serving for heat exchange has, at least in sections, a wall made of aluminum or an aluminum alloy.
  • the invention is therefore based on the object to develop a heat cell, with a higher integration of different functional units is achieved.
  • the invention includes the technical teaching to provide a heat cell for a hot water generator with a support member having a housing shell within which are arranged with the ends by the housing shell outwardly guided coiled tubing for a heat transfer fluid as a heat exchanger and in this a burner unit, with a lid and bottom element closing off the housing jacket, wherein the holding element and at least a part of the housing jacket are formed in one piece.
  • the invention is based on the consideration that a high integration of several functional units is achieved by the one-piece design.
  • the support member is either fixed to a part of the housing shell, for example, on a wall surface, or even with little effort from a base carrier removably formed.
  • a basic carrier can serve a simple wall-side metal sheet.
  • the ends of the tube spiral guided outward through the housing jacket or the retaining element can be located in different planes and can be arranged offset relative to one another. Also, a non-linear connection of the two passage levels is being considered.
  • the advantages achieved by the invention by reducing the number of components in a device are, in particular, that the heat cell can be realized more efficiently, in terms of manufacturing technology, simpler and thus less expensive.
  • such heat cells can be adapted to the overall design with little design effort and into the plants be installed for hot water production.
  • Higher integration saves additional components and associated additional connections.
  • the attachment of the pipe ends of the helix can be carried out correspondingly inexpensively and the desired higher integration of various functional units in a housing part can be realized. This can also achieve an increase in the efficiency of these heaters.
  • the integrally formed part of the heat cell can be made of a press profile.
  • Such profiles can be manufactured particularly cost-effective in large quantities.
  • the integrally formed part may preferably be made of aluminum or of an aluminum alloy.
  • the housing shell may consist of two cylindrical half-shells, one of which is formed integrally with the support member. This too can be realized by means of pressing profiles due to the symmetry conditions.
  • the attachment of the tangential pipe ends of the helix should be carried out as inexpensively and be reduced by a high integration density as possible, the number of components in a device.
  • the ends of the coiled tubing may be passed through the holding element perpendicular to the surface thereof.
  • a pipe section of a running along the housing shell Exhaust pipe to be formed integrally with the support member and / or at least with a half-shell of the housing shell.
  • At least one of the pipe ends can each open into a flow channel formed in the support element or return side channel for the heat transfer fluid, wherein the flow or return end of the channel is configured connectable to the periphery.
  • the flow or return-side channel can extend through the cover element and / or at least along a section on the housing jacket.
  • the heat transfer fluid can be performed independently of the arrangement of the coiled tubing by the pipe ends are no longer led to the periphery itself, but open into an additional channel within the heat cell.
  • the heat cell is cooled on its outer wall and in the lid area.
  • the heat is selectively supplied to the heat transfer fluid and contributes to the increase in efficiency. In this case, if necessary, even the otherwise usual lid-side insulation can be saved.
  • the housing wall facing away from the rear wall of the support member may be formed substantially flat.
  • the resulting connection surface of the support member is formed in a simple manner on a wall surface or connectable to a base support. In the case of a press profile, however, uniformly flat surfaces will necessarily be present only in the pressing direction for constructional reasons.
  • the air outlet of the intake air from the cavity can advantageously be performed via a hose directly into the intake of the blower unit connected to the burner unit.
  • the air inlet of the intake air can be guided directly from the environment into the cavity via a hose line.
  • the air inlet into the cavity and the air outlet from the cavity can take place without positive guidance alternatively in a preferred embodiment.
  • longitudinal grooves for fixing peripheral parts can be arranged on the integrally formed part of the heat cell.
  • the longitudinal grooves for example on a press profile, also belong to the integral part of the one-piece support element and housing shell.
  • Such longitudinal grooves can serve, for example, for receiving and fixing sensors for the housing temperature or as guide slots for electrical lines.
  • a groove results in an increase in the wall thickness, which as a whole contributes to a stiffening of the overall structure.
  • the schematic representation of the heat cell 1 according to FIG. 1 consists of a double-walled housing jacket 3 and 9 for the supply air of the burner unit.
  • the support member 2 is formed integrally with the half-shell 32 of the cylindrical housing shell 3.
  • Particularly cost-effective proves for the one-piece component is a press profile made of aluminum or an aluminum alloy.
  • the second half-shell can be made of a press profile.
  • the rear wall 23 of the support member forms a flat surface for easy mounting on a wall-side base support.
  • longitudinal grooves 24 are arranged for attachment of peripheral parts. Each longitudinal groove 24 reinforces the wall thickness locally and causes a stiffening of the overall structure, which can be configured with a smaller wall thickness.
  • the pipe ends 41 and 42 thereby form an angle of 90 ° with the plane of the press profile, whereby a simple round weld is applied to seal the passage point.
  • Due to the planar design of the respective housing wall segment thus a simplified two-dimensional, lying in a plane mounting the helix with the profile is possible.
  • a seal by means of an O-ring is conceivable.
  • the solution envisaged in the prior art is not a plane, the opening through the jacket for the ends of the coiled tube forms an elliptical shape.
  • the sealing of the pipe ends relative to the housing shell is correspondingly more expensive.
  • the second half-shell 31 is detachably connected by means of a screw connection, however, both half-shells can also be joined by a welded connection, for example.
  • the spirally extending coiled tubing 4 is arranged for heat exchange, the tube ends 41 and 42 are guided through the housing shell 3 and in this case by the support member 2 to the outside.
  • the burner unit not shown here, is arranged in the operating state.
  • the housing jacket 3 enclosing the heat cell 1 is surrounded by a further outer housing jacket 9, whereby the cavity 91 is formed between the housing envelopes 3 and 9, through which the supply air for the burner unit is guided during operation.
  • the supply air is collected via the hose 11 and fed to a blower.
  • the schematic representation of the heat cell 1 according to FIG. 2 consists of a double-walled housing jacket 3 and 9 for the supply air of the burner unit, in which a part of the exhaust pipe 8 is also integrally formed on the support member 3.
  • a correspondingly high integration of various functional units in a housing part is realized.
  • the integration of other brackets for cover, floor and wall mounting in the housing parts is conceivable.
  • Fig. 3 shows a longitudinal section of a heat cell 1 with double-walled housing shell for air preheating with hose connections for guiding the supply air.
  • the enclosing housing shell 3 is surrounded by a further outer housing shell 9 only partially.
  • the supply air for the burner unit 5 flows through a hose 11 into the air inlet 92 along the housing shell.
  • the heated air is collected at the air outlet 93 by a further hose 11 and forwarded to the fan unit 10 to the burner unit 5.
  • the blower unit 10 is connected to the burner unit via the cover element 6, which closes off the housing jacket 3. Boden note the housing shell is closed by a bottom element 7.
  • a feature of this design is the closed unit of inner and outer shell casing, i. the air can only flow in a defined channel.
  • the supply air for the burner unit 5 without forced guidance from the housing environment in the open air inlet 92 between the housing shell 3 and the outer housing shell 9 and is again collected at the air outlet 93 through the hose 11 and the Blower unit 10 to the burner unit 5 forwarded.
  • the heated air is fed to the fan without targeted flow guidance.
  • the passing past the hot housing jacket air is heated.
  • ribs or webs can be mounted either directly on the hot metallic housing shell 3 or on the outer housing shell 9. When mounted directly on the hot housing shell 3, the heat transfer is improved.
  • the air inlet is preferably at the bottom of the housing to enhance the cooling effect.
  • Fig. 5 shows the execution of different rear walls of the support member.
  • the pressing profile in the region of the continuous pipe ends is designed substantially flat so that the pipe ends and the plane of the press profile are at an angle of 90 ° zueinender.
  • alternative embodiments may provide significant freedom in the structural design of the support member 2.
  • the profile is continuous by pressing only in the flow direction of the material, other directions are largely freely designable.
  • FIG. 5C shows, the ends do not necessarily have to emerge parallel to each other, but also can also be arranged offset. It is also conceivable that an outlet is housed in each press profile half shell.
  • the channels produced integrally in the profile may alternatively be water-carrying as an alternative to the air guide and then serve primarily to cool the housing wall.
  • the water supply in the one-piece press profile can be done via connecting pieces (fittings) via the pipe ends to the pressing profile directly, or via the housing cover.
  • Another possibility of Wasserzuund-removal is the confluence of at least one of the pipe ends 41, 42 within the profile channel.
  • Fig. 6 shows a cross section of the heat cell 1 with channels 21 and 22 for water as a heat transfer fluid in the support member 2 and the housing shell 3.
