Definitions
- the invention relates to a heat exchanger for an air heater for integration into an air-conducting housing, which has a heat exchanger body with a longitudinal axis auf ⁇ .
- the invention further relates to various methods for producing a heat exchanger for an air heater for integration into an air-conducting housing, in particular a housing of a vehicle air conditioner, wherein the heat exchanger has a heat exchanger body with a longitudinal axis aufwei ⁇ send heat exchanger core and heat transfer surfaces up.
- auxiliary heaters for vehicles are mainly installed separately from the vehicle's own heating / air-conditioning unit, also referred to herein as a vehicle air-conditioning unit.
- Der ⁇ like additional heaters are, for example, realized as Heilmorege ⁇ devices that are used as auxiliary heater and / or as StandMapun ⁇ conditions.
- One problem is related to the high weight of the heat exchanger body, which is generally produced by a pressure casting technique. Due to the high weight, in particular, the housing carrying the vehicle heater must be designed to be correspondingly stable.
- the heat transfer from the combustion gases to the heat exchanger furthermore plays an important role.
- This heat transfer should also be improved, in order to be able to thereby provide, in particular, greater freedom in the construction of the heat exchanger.
- an air heater Another important requirement for an air heater is to arrange it so that a passage of combustion gases is excluded in the air flowing around the air heater. Furthermore, it is to be ensured that the air used for the combustion is taken from the outer region of the motor vehicle, that is to say, in particular, not from the interior. An improvement with regard to the location of the various connecting pieces of the air heater is also desirable.
- the invention is based, at least in part, to overcome the abovementioned problems by appropriate solutions, in particular with regard to the flow behavior and the heat transfer.
- the invention builds on the generic heat exchanger in that the heat exchanger body on its outer side has a plurality of substantially along the circumference extending corrugated fins that provide heat transfer surfaces available.
- the corrugated shape of the ribs improves the heat transfer from the heat exchanger to the air to be heated, which flows through the spaces between the ribs, in particular due to the enlargement of the surface area available for the heat transfer. Furthermore, the ribs obtained by the corrugated shape increased stability.
- the heat exchanger body has a heat exchanger core and that the plurality of corrugated fins is at least partially applied to the heat exchanger core by means of a separate component or as separate components.
- This separate production possibility is considered to be advantageous against the background of a possible weight reduction and a higher variability with regard to the design of the components and the production methods.
- the crabtau ⁇ shear body has a heat exchanger core and that the plurality of corrugated fins is at least partially einstü ⁇ ckig formed with the heat exchanger core.
- the plurality of corrugated fins shrunk onto the heat exchanger core and / or pressed on. It makes sense not to fasten such heat transfer surfaces to the heat transfer core via screw connections or similar connections, but rather by welding, soldering, shrinking or pressing on one or more pushed-on surface parts or entire packages.
- the invention is based on the generic method da ⁇ by the fact that the politicians (2004)leyerAveman on its outer side has a plurality of substantially along the circumference extending corrugated fins, which provide kilometers await ⁇ ⁇ geropter available, the kilometersleyer ⁇ core and the corrugated fins at least partially be made separately.
- the advantages and particularities of the heat exchanger according to the invention are also realized in the context of a method.
- the invention also builds on the generic method in that the heat exchanger body on its outer side a plurality of essentially along the circumference extending corrugated fins auf ⁇ has, provide the heat exchanger surfaces available, the heat exchanger core and the heat exchanger surfaces are made in one piece.
- the cherrieshielleyerk ⁇ rper and the heat exchanger bottom are made separately.
- Such a multi-part design of the heat exchanger body increases the variability with regard to possible structural variants as well as with regard to possible production methods.
- by manufacturing the heat exchanger bottom separately from the heat exchanger core it is possible to use additional manufacturing methods for the heat exchanger core. With a suitable choice of the manufacturing process can thereby reduce the weight of the heat exchanger.
- heat exchanger head is provided. If such a heat exchanger head is present, the separate production makes sense. Depending on the geometric design of the burner head or the burner unit, however, it is also possible to completely dispense with the heat exchanger head. It is possible that the heat exchanger core is manufactured as diecasting part. Although such a die-cast part is comparatively heavy, it is comparatively inexpensive to manufacture on the other hand.
- the heat exchanger core has an inner profile.
- the heat-transmitting inner surface of the heat exchanger can be increased, so that in turn the total space can be reduced in total.
- the heat exchanger core is manufactured in an extrusion molding process.
- the wall thicknesses of the heat exchanger can be selected to be lower in comparison to diecasting processes, in particular due to non-demanding draft angles, so that the total weight can be reduced.
- Thinner internal ribbing can also be provided in comparison to diecasting, so that in turn an enlarged heat-transmitting inner surface is provided.
- the extrusion process it is possible to integrate in the extruded profile, the geometry for Be ⁇ consolidation of heat exchanger head, burner, (2004)erbo ⁇ the etc., for example in the form of core holes for holes.
- cross-sectional geometry is oval.
- cross-sectional geometry of the cross-sectional geometry of an aircraft wing is similar.
- cross-sectional geometry may be spindle-shaped.
- the heat exchanger body has on its outer side a plurality of rods which provide heat transfer surfaces available. By means of such a multiplicity of bars, a very large surface can be made available for heat transfer to the air to be heated.
- the heat exchanger body may have a heat exchanger core and for the plurality of rods to be applied at least partially to the heat exchanger core by means of a separate component.
- the heat exchanger body prefferably has a heat exchanger core and for the plurality of rods to be formed at least partially in one piece with the heat exchanger core.
- the rods on a separate component or in one piece with the heat exchanger core, different advantages can be recognized, for example on the one hand with regard to variability and on the other hand with regard to the simplicity of the overall manufacturing process.
- the heat exchanger body is constructed from a plurality of heat exchanger body modules. Also this in turn increases the variability, since differently structured and, in particular, different sized heat exchangers can be produced from individual heat exchanger body modules.
- the heat exchanger body modules are manufactured in a die casting process. If you do not want to deviate from the production of the heat exchanger in the conventional die-casting process, the modular production offers advantages, since only short and thereby less demanding draft angles are erforder ⁇ Lich.
- the heat exchanger body modules are at least partially identical. There are then, especially in the case of the die-casting process, no different tools required.
- the heat exchanger body is at least partially manufactured in a pressure casting process using two cores, the cores being removed in opposite demolding directions. As a result, the maximum thickness of the Entformungsschrägen can be reduced, resulting in a weight saving.
- the flow guide elements are designed in the manner of a screw thread, as blades, meander-shaped components, baffles and / or perforated tubes. These and many other possibilities improve the overall heat transfer.
- a flange plate is provided by means of sealing elements between a Montagestel ⁇ le for the air heater and the flange plate and zwi ⁇ tween the air heater and the Flange plate at least ei ⁇ ne exhaust discharge seals against the vehicle interior.
- a flange plate ensures that the exhaust gas can be conducted to the outside air as short a path as possible, whereby there is no danger of exhaust gases entering the interior of the vehicle.
- the flange plate seals a combustion air supply against the Anlagenin ⁇ nenraum.
- the combustion air is taken from the exterior of the vehicle.
- the flange plate has a passage for a fuel supply.
- all connections through which gases and liquids are transported are located in the area of the flange plate.
- the invention is based on the finding that an air heater can be integrated into a heating air conditioning system of a motor vehicle, in particular of a commercial vehicle, in an economical manner which is suitable with regard to functionality. This can be attributed in particular to the positive properties of the heat exchanger with regard to the flow and heat transfer behavior.
