Definitions

the present invention relates to a heat exchanger arrangement for a Heating device, in particular a motor vehicle heating device, comprising a pot-like housing with a bottom area and a wall area, being on a side facing the housing interior of the A floor protrusion arrangement is provided;
DE 196 13 760 A1 discloses a heat exchanger arrangement for a Heater, wherein this heat exchanger arrangement is pot-shaped and surrounds a combustion chamber with its wall area. The one from the Hot exhaust gases emerging from the combustion chamber hit the floor area, are deflected axially there and then flow along the wall area to the axially open end of the heat exchanger housing.
a Heat exchanger arrangement for a heating device in particular a Motor vehicle heater, comprising a pot-like housing with a Bottom area and a wall area, one of which is the interior of the housing facing side of the floor area a floor protrusion arrangement is provided.
the floor protrusion arrangement at least one in the direction of the wall area includes extending rib-like bottom projection.
the heat exchanger housing Due to the inventive design of the heat exchanger housing on the one hand it ensures that by increasing the surface area good heat transfer capacity by enlarging the heat transfer surface provided. Provision is essential for this at least one rib-like projection on the bottom area.
the orientation of this rib-like projection namely in Direction away from the wall, for example approximately with radial orientation in relation to a longitudinal central axis of the housing, for the fact that in the floor area hitting the housing and there in the Generally heated gas radially outward and then axially redirected when flowing along a comparatively large surface experiences significantly lower gas flow resistance than when providing a variety of pin-like projections is the case.
the bottom projection arrangement a plurality of has base projections arranged in a star-like configuration. Due to the star-like configuration, as already mentioned, at Enlarged overall surface for the lowest possible flow resistance taken care of. It can be provided, for example, that the Floor protrusions extend from a central area of the floor area Extend towards the wall area. To flow around the rib-like To hinder protrusions as little as possible, it is suggested that the floor protrusions are in their closer to each other End areas are not connected.
the Bottom projections are curved, preferably opposite the swirl direction of a fluid flow flowing towards the bottom region is curved is trained. Enable by the curved design the bottom projections a better entry of the incoming fluid or the incoming gas in the space between the individual floor protrusions and thus reduce the flow resistance.
a wall projection arrangement is provided, comprising at least one bottom projection of the bottom projection arrangement assigned one adjoining this and moving towards wall projection extending away from the floor area. Also at Flow along the wall area is thus for the heated gas an enlarged surface is provided.
the flow resistance can already be provided in the floor area can be further reduced.
This can be further preferred be provided that in a transition area between the Floor area and the wall area at least one floor projection merges into a wall projection essentially without interruption.
the wall projection arrangement at least has a wall protrusion on which no base protrusion followed.
a wall projection can then, for example, in the Be provided between two wall projections connect an assigned floor protrusion.
the one or more wall projections can be designed such that they approximately in the direction of a longitudinal central axis of the housing extend.
the present invention further relates to a heating device, which a Has heat exchanger assembly according to the invention.
Fig. 1 is a general view of the essential components shown with 10 heater, such as as Auxiliary heating or auxiliary heater can be used in a motor vehicle can.
the heating device 10 includes one generally designated 12 Combustion chamber, from which a flame shield 14 is used during combustion resulting heated gases in the flame tube 16 enclosed space extending along a longitudinal axis L. 18 occur.
the flame tube 16 is at its from the combustion chamber 12 distant end portion 20 axially open.
An essentially pot-shaped housing 22 of a heat exchanger arrangement 24 surrounds the flame tube 16 radially on the outside and lies with its bottom region 26 the axially open end region 20 of the flame tube 16 opposite.
One at the bottom area 26 in a connection area 28 adjoining wall area 30 of the housing 22 extends approximately parallel to the flame tube 16 and approximately also along the longitudinal axis L, which is also a longitudinal center line for the flame tube 16 and the housing 22 forms.
annular space area 32 is formed between the flame tube 16 and the wall area 30 of the housing 22 . That from the axially open end area 20 of the flame tube 16 escaping heated gases meet the Bottom area 26 and are there, as shown in Fig. 1 by arrows, first deflected radially outwards and then in the axial direction, see above that they are along the flame tube 16 and the wall region 30 again towards the combustion chamber 14 and radially outside of it be given outside.
Housing 22 of the heat exchanger assembly 24 on its outside surround another housing 36, commonly referred to as a water jacket is.
a water jacket is another housing 36, commonly referred to as a water jacket.
rib-like elevations 38 are provided, which ensure that the to warming liquid in the best possible heat transfer contact with can enter the housing 22.
the housing 22 instructs its bottom region 26 on the inside of the housing, that is to say Flame tube 16 facing side 40 a generally designated 42 Floor protrusion arrangement on.
the bottom projections end in their radially inner region 46 44 near the central region 48 of the base region 26 there, however, not in mutual connection. It will be close to that central area 48 is essentially enclosed by end areas 46 Space area 50 is formed, in which the central area of the flame tube 16 flowing gases can occur. At the redirection these gases then pass radially outward through the spaces 52 between two bottom projections 44 and radially outwards In this way it is ensured that at the bottom area 16 no room or shielded or blocked against flow Volume areas arise.
an inner side 31 recognizable wall projection arrangement 54 is also provided in the figures.
This comprises a plurality of wall projections 56, which extend along the housing 22 or the wall region 30 extend approximately in the direction of the longitudinal axis L. It can be seen that in the transition region 28 each of the bottom projections 44 merges into a wall projection 56 assigned to this, this transition is preferably designed without interruption. Furthermore, between each two wall projections 56 to which one Bottom projection 44 connects, a wall projection 56 'is provided in each case, to which no bottom projection 44 connects. One recognizes before all in the top view of FIG.
An essential characteristic of the configuration according to the invention of the housing 22 is that at a comparatively large for heat transfer contributing inner surface the flow resistance for that Flame tube 16 leaving heated gases kept comparatively low is because of the different protrusions which increase the overall surface contribute in the direction of flow, which for the heated gases is predetermined or provided. This will the total flow resistance for those generated during combustion heated gases are kept small, which is a very efficient operation of the Heating device allowed.
FIG. 4 shows a view of a bottom region 26 of an alternative embodiment Housing 22. It can be seen here that the bottom projections 44 are curved from radially outside to radially inside, so that in the area of radially inner free end portions 46 of these one extension directional component have in the circumferential direction. That from the combustion chamber 14 has heated gas flowing along the flame tube 16 Due to the conveying effect of a blower used, which is indicated by the arrows in Fig. 4. By the opposite configuration of the floor protrusions curved in this swirl direction 44 becomes in the axial direction and with a twist towards the bottom region 26 flowing heated gas an easier entry into between each allows two of the bottom projections 44 formed space and thus a reduction in flow resistance is achieved.
