Description

Vehicle heating system

Technical Field

The present invention relates to a vehicle heating system that may be used to heat a parked vehicle.

Background

Such vehicle heating systems, which are also generally referred to as parking heaters, are designed in such a way that a fuel-operated heater which transfers heat to the medium to be heated is fixedly installed in the vehicle, usually in the region of the engine compartment. The heater is connected to a medium guide system of the vehicle, for example, in order to introduce air heated by the heater into the vehicle interior via the medium guide system or to introduce heated liquid into a coolant circuit of the vehicle internal combustion engine. The heater is also connected to the vehicle electrical system, on the one hand, in order to supply the heater, in particular the control device associated with the heater and/or the pump for delivering fuel to the vehicle heater, with electrical energy, and on the other hand, in order to transmit information about the operating state, in particular the thermal state, of the vehicle to the heater.

Disclosure of Invention

The object of the present invention is to provide a vehicle heating system which, with a simple design, has a high degree of flexibility in operation and nevertheless has a good heating capacity for the vehicle to be heated.

According to the invention, the object is achieved by a vehicle heating system comprising:

-a heating-receiving container mounted or mountable on a vehicle,

-a fuel-operated heater disposed in the heat receiving vessel,

-a fuel tank for a heater arranged in the heating-receiving container.

The vehicle heating system constructed according to the invention, together with its main system components, is designed as a system which is substantially independent of the vehicle construction. This means that the vehicle heating system can also be operated in principle independently of the vehicle. Since the vehicle heating system is structurally and functionally separate from the vehicle, it is on the one hand easy to implement to add such a vehicle heating system to any vehicle or to operate such a vehicle heating system in combination with a very different vehicle. The vehicle heating system does not need to be guided in a portable manner with the vehicle. When a vehicle to be heated by means of such a system is operated in driving mode, the heating system or at least parts of the heating system can be left in a garage, for example.

Since the vehicle heating system according to the invention or its main system region is arranged in a heating receptacle provided for this purpose, no significant installation space is required on or in the vehicle itself. Thus, not only the outlay for integrating the vehicle heating system into the vehicle, but also the outlay for this purpose for coupling the vehicle heating system to an electrical system of the vehicle (for example an on-board power supply system or a data transmission path) are not taken into account. A further advantage is that the volume formed inside the heating receiving container can also be used for receiving further objects to be transported, for example by means of a vehicle.

In order to make the vehicle heating system further independent of the system area of the vehicle, it is proposed that: the heater is provided with an operating device arranged in the heating receptacle or/and a fuel pump arranged in the heating receptacle or/and at least one electrical energy store. In particular, the provision of at least one vehicle-independent electrical energy store yields the following advantages: the vehicle's on-board power supply system is not loaded by the vehicle heating system. The same applies to the provision of fuel for operating the vehicle, since the heater is provided with a fuel tank which is independent of the vehicle. This allows the heater to be operated also with additional fuel, which, for example, in combustion mode, causes less harmful emissions than the internal combustion engine of the vehicle. By structurally and functionally decoupling the vehicle heating system from the vehicle, the vehicle heating system is also suitable, in particular, as a parking heating for electrically operated vehicles, which usually have no fuel tank.

For a space-saving design, it is proposed: at least one electrical energy store is arranged in the heating receiving container. In addition, provision can be made for: at least one electrical energy store is arranged in the vehicle carrying the heating receptacle, wherein an electrical connection to the heater can be established via a line to be led out of the vehicle. In order to be able to recharge such an electrical energy store independently of the operation of the vehicle, it is proposed that: at least one electrical energy store can be removed from the vehicle heating system and can be electrically connected to the vehicle heating system via an interface. Thus, an energy store which is removed from the vehicle heating system or vehicle can be connected for charging purposes, for example, to an electrical network which is present in a garage or a building during driving operation of the vehicle (i.e. when the vehicle heating system is not to be operated).

In one embodiment, provision can be made for: at least one electrical energy store is associated with a charging unit.

For example, such a charging unit may comprise a solar module, preferably carried in a positionally changeable manner on the heating receptacle, or/and a wind wheel unit, preferably carried in a positionally changeable manner on the heating receptacle. It is thus possible to recharge the at least one electrical energy store by means of the charging unit even during heating operation or during vehicle driving operation. In this case, it is particularly advantageous to arrange the solar modules or wind turbine units on the heating and receiving container in a positionally changeable manner, since this can ensure an optimum orientation with respect to the sun or the air flow, and thus an efficient charging operation, in particular by independent implementation of the respective charging unit.

In order to transfer the heat provided during the heating operation of the heater to the vehicle, it is proposed that: the heater is provided with a heating medium guide device for guiding the heating medium output from the heater into the vehicle.

It can be provided here that the heating medium guiding device comprises a preferably flexible guiding region for guiding the heating medium away from the heater, or/and that the heating medium guiding device comprises a heating medium discharge device for discharging the heating medium into the vehicle.

In an auxiliary configuration for the flexible use of the vehicle heating system according to the invention, it is proposed that: the heating medium discharge device is preferably detachably mounted or mountable on the vehicle in the region of the open window. Alternatively, the heating medium outlet device can be mounted fixedly on the vehicle and comprises an interface for connecting the guide region.

In a configuration which is particularly advantageous with regard to the protection of the vehicle to be heated and also with regard to the thermal efficiency, a flexible covering can be provided which at least partially covers the vehicle. Such a cover ensures that the heated medium which is discharged from the heater efficiently transfers the heat which is transported therein to the vehicle and avoids heat losses to the outside as much as possible, and in particular also prevents ice from forming on the outside of the vehicle in the winter season.

It is proposed that the medium discharged from the heater is discharged into an interior space covered by the housing and/or that the medium discharged from the heater is discharged into a medium guide channel arranged in the housing.

In order to discharge the medium discharged from the heater into the inner space covered by the housing through the medium guide passage, it is proposed that: an opening is provided in the medium guide channel for discharging the medium flowing through the medium guide channel into the interior covered by the cover.

The housing may comprise at least one air-fillable housing shaping cavity. In this case, a blower for conveying air into the at least one housing shaping chamber and/or at least one valve for retaining air in the at least one housing shaping chamber are preferably provided.

In order to distribute the heat transferred to the vehicle by the medium heated in the heater uniformly in the interior of the vehicle, it is proposed: an air supply unit which is or can be arranged in the interior of the vehicle to be heated is provided with at least one electrically operable blower.

In order to provide the air supply unit with electrical energy, the air supply unit can be connected or can be connected to at least one electrical energy accumulator associated with the heater.

In particular, when such an electrical energy store is provided, for example, in a heating receptacle, i.e. outside the vehicle to be heated, a wireless coupling path device can be provided for coupling to the at least one electrical energy store.

The heating-receiving vessel is preferably configured for mounting on:

on vehicle roofs, i.e. as roof boxes, or/and

on the trailer coupling, or/and

in the region of an open vehicle window, or/and

-in the rear region of the vehicle.

In order to be able to ensure suitable thermal conditions for efficient operation of the heater or/and the transported object, the heater can be configured for warming the interior space of the heating receiving container.

Detailed Description

Fig. 1 shows a vehicle 10 in a schematic representation, which has a vehicle heating system 12 arranged thereon. The vehicle heating system 12 is constructed or operable in a substantially self-sufficient manner from the vehicle 10 and has a heat receiving container 14 that is externally mounted or mountable on the vehicle 10. The heating receptacle is configured as a roof box in the exemplary embodiment shown in fig. 1 and is mounted on a roof 16 of the vehicle 10 (e.g., on a roof rack).

A heater, which is operated with a fuel, generally indicated at 18, is arranged in the interior of the heating receiver vessel. The heater has a combustion air blower that supplies air required for combustion to the combustion chamber structure assembly of the heater 18. Furthermore, a fuel tank 20 associated with the heater 18 is provided in the interior of the heating-receiving container 14, in which fuel required for combustion with the combustion air can be stored. The fuel may be supplied to the combustion chamber assembly of the heater 18 by a fuel pump 22, such as a metering pump, to form a mixture of combustion air and fuel therein. Exhaust gas generated at the time of combustion may be output outward from the heater 18 and the heater receiving container through an exhaust gas guide system not shown.

It is to be noted in this connection that such a heater 18 usually also comprises a heat exchanger in which the medium to be heated, i.e. for example the air to be introduced into the vehicle interior, receives heat from the combustion exhaust gases. Such a heat exchanger can have a heat exchanger housing, which can be flowed around or through by the combustion exhaust gas on its inside and can be flowed around or through by the medium to be heated on its outside or by the heat carrier medium flow volume formed therein. The line open to the surroundings can lead the air conveyed by the blower to a heater 18 arranged inside the heat receiving container in the case that air is used as the medium to be heated.

Furthermore, the heater 18 is assigned an actuating device which can be integrated, for example, in the heater 18 and controls or regulates (open-loop or closed-loop control) the operation of the different system regions of the heater 18. These system areas can include, for example, a metering pump 22, an ignition mechanism (i.e., a glow head, for example), a blower for combustion air, and also a blower for delivering heated or to-be-heated air if the heater 18 is used for heating air.

In order to supply these electrically operable system regions with electrical energy, the vehicle heating system 12 also has at least one electrical energy store 24, i.e. for example a battery or the like. In the exemplary embodiment shown in fig. 1, the electrical energy store 24 may be situated in the interior of the vehicle 10 and be electrically connected to the system region of the vehicle heating system 12 situated in the interior of the heating receptacle 14 and intended to be operated electrically via electrical lines 26 which are to be routed out of the vehicle 10. It is to be noted in this connection that, of course, the electrical energy store or, if appropriate, a further electrical energy store 24 can be arranged inside the heating receiver container 14, so that, if appropriate, electrical line connections to the interior of the vehicle 10 can be dispensed with.

The electrical energy store 24 can be fixedly installed in the vehicle heating system 12. Preferably, however, the electrical energy store 24 is designed in such a way that it can in principle be detached from the vehicle heating system 12 and can be electrically coupled via an interface to the system region of the vehicle heating system 12 to be operated electrically. This allows: for charging, the electrical energy store is removed from the vehicle heating system 12 or the vehicle 10 and is charged in the building by a corresponding charging station.

For charging the electrical energy store 24, it may alternatively or additionally also be provided that: the vehicle heating system 12 has a charging unit, generally indicated at 28. By means of the charging unit 28, electrical energy can also be supplied to the electrical energy store 24 for storage during a heating operation of the vehicle heating system 12 or during a driving operation of the vehicle 10.

The charging unit 28 can have, for example, a solar module 30. The solar module 30 is preferably carried on the heat receiving container 14. For example, the solar module 30 can be assigned a drive by means of which the solar module can be moved out of and into and can be automatically oriented according to the position of the sun, so that an efficient charging operation is ensured.

Alternatively or additionally, the charging unit 28 may have a wind wheel unit 32. The wind wheel unit is also preferably mounted on the heat receiver container 14 in such a way that, by means of a drive assigned to the wind wheel unit, it can be oriented in such a way with respect to the air flow circulating around the heat receiver container 14 that an efficient charging operation is ensured.

FIG. 1 also shows that the vehicle heating system includes a housing 34 that substantially completely encloses the vehicle 10 in the illustrated embodiment. The cover can be attached to the heat receiver 14, for example, and has such a shape that it extends as far as into the lower edge region of the body of the vehicle 10. The cover 34 on the one hand prevents the formation of an ice layer on the outside of the vehicle 10 when the vehicle is parked open and the ambient temperature is low. On the other hand, this cover 34 forms a heat insulation which, in a manner which will be described in more detail below, ensures that the heated medium (i.e. for example heated air) output from the heater 18 can be used efficiently for heating the vehicle 10.

Fig. 2 shows an alternative embodiment of the vehicle heating system 10. In the embodiment shown in fig. 2, the heating receptacle 14 is carried in the rear region 36 of the vehicle (for example on a trailer coupling, not shown, or on a tailgate or a trunk lid of the vehicle 10) together with the system region (in particular the heater 18) arranged therein. In this version of the configuration, the vehicle 10 may also be concealed by the cover 34.

Fig. 3 shows how the medium heated by the heater 18 (in the illustrated embodiment heated air) can be introduced into the interior 38 of the vehicle 10. For this purpose, a heating medium guide, generally designated 40, is provided. The heating medium guide has a preferably flexible guide region 42 which leads away from the heater 18 and out of the heat receiving container 14 and which guides the air heated by the heater 18 in the direction of a heating medium outlet 44. In the exemplary embodiment shown in fig. 3, the heating medium discharge device 44 is designed in such a way that it is basically designed separately from the vehicle 10 and can be arranged, for example, in the region of an open window 46 of the vehicle 10. The heating medium outlet device 44 may have, for example, a box-shaped container which receives the heated air conveyed via the guide region 42 and outputs it into the vehicle interior 38 via a plurality of openings located toward the vehicle interior 38. In this case, the heating medium discharge 44 can be clamped, for example, by a window 46 and thus fixed, for example, in the region of a door 48 of the vehicle 10.

Fig. 4 shows a further alternative embodiment of the vehicle heating system 12. In the illustrated embodiment, the heating receptacle 14 is configured or dimensioned in such a way that it can be mounted analogously (as described above with reference to fig. 3) in the region of an open window of the vehicle 10 and can be clamped, for example, by the window. The heater 18 is arranged inside the heating receiver container 14 together with the system regions also described above and assigned to it, in particular the fuel tank 20 and the fuel pump 22. For the purpose of discharging the heated medium (i.e. air in the illustrated embodiment) into the interior 38 of the vehicle 10, the heat receiver container may have one or more openings on its side facing the interior 38, through which the heated air can be conducted out of the heat receiver container. Alternatively or additionally, the guide region leading away from the heater can be guided through the heating-receiving container 14 to an opening formed therein, so that in said region the heated air can then be output into the vehicle interior 38.

Fig. 5 shows another alternative embodiment. Here, the heating reception vessel is also arranged in the rear region 36 of the vehicle 10. In the illustrated exemplary embodiment, the heating medium outlet 44 is mounted fixedly on the vehicle and can be coupled via an interface to the guide region 42, which guides the heated air or the heated medium out of the heating receptacle 14. In particular, the form factor may be such that, when the heating receiver 14 is mounted on the vehicle 10, a connection is automatically produced between the guide region 42 and the heating medium discharge device 44.

Fig. 6 and 7 show a configuration pattern of the vehicle heating system 10 with the cover 34 substantially completely covering the vehicle 10. For example, in the embodiment shown in fig. 1, the cover 34 is designed such that, due to its flexibility, it rests against the outside of the vehicle 10 or lies there, whereas the cover 34 shown in fig. 6 and 7 is designed such that its shape, in particular the shape assumed during operation of the vehicle heating system 12, is essentially independent of the vehicle shape. For this purpose, the casing 34, which is attached to the heating receiver container 14, for example in the upper region, can have a plurality of casing shaping chambers 50 into which air is conveyed, for example by a blower which is arranged in the heating receiver container 14 and which is constructed separately from the heater and which can also be supplied with electrical energy, for example by an electrical energy store assigned to the heater 18. By means of the air pressure thus established (which can be maintained, for example, by means of a blower which is continuously operated during the heating operation), the housing shaping chamber assumes a defined contour which, for example, ensures that an air cushion is produced between the inside of the housing 34 and the outside of the vehicle 10.

In a variant which is particularly advantageous for energy-saving operation, it can be provided that: the blower for building up pressure in the housing shaping chamber or chambers is/are operated only for conveying air and for building up pressure. In order to maintain air pressure in the one or more housing shaping chambers, at least one valve may be provided to prevent air from escaping. To build up air pressure, a blower may deliver air through the valve. The valve can be automatically switched into the closed position when air pressure builds up in one or more housing shaping chambers and when no delivery pressure is present after the blower has been deactivated. In order to evacuate air from the housing shaping chamber or chambers, such a valve can be brought into a release state, in which air can escape from the housing shaping chamber or chambers, for example by manual actuation or by activating an actuator assigned to the valve. A plurality of valves may also be provided, wherein air may be conveyed into the housing shaping chamber through one or more of said valves and air may be discharged from said housing shaping chamber through one or more further valves.

In the embodiment of the configuration shown in fig. 6 and 7, the interior 52 covered by the covering 34 substantially completely accommodates the vehicle 10, whereas in the embodiment of the configuration shown in fig. 8, the covering 34 is designed such that only the upper region, which in particular also includes the vehicle window, is accommodated in said interior 52 and covered by the covering 34.

Fig. 9 shows a part of the casing 34 with a casing shaping cavity 50 formed therein, into which air is conveyed by the already mentioned blower in order to give the casing 34 the desired shape. Furthermore, a medium guide channel 54 extends in the housing 34, into which medium heated by the heater 18 (in particular, heated air) is guided. The medium flowing through the medium guide channel 54 can transfer the heat transported therein via the housing 34 towards the air present in the concealed interior 52, so that the vehicle positioned in said interior 52 is in turn heated. For example, it can be provided that: the medium exits the medium guide channel 54 in the lower region of the housing 34.

Fig. 10 and 11 show an opening 56 assigned to the medium guide channel 54, through which the medium (i.e. for example heated air) can flow out into the interior 52 covered by the outer cover 34. Direct thermal contact between the heated medium entering the interior 52 and the region of the vehicle 10 covered by the hood 34 can thus be achieved, as is shown in fig. 12.

To ensure that the heat transferred to the vehicle 10 is evenly distributed in the vehicle interior space 38, the vehicle heating system 12 may also include an air delivery unit 58 positioned or positionable in the vehicle interior space 38. The air supply unit can be positioned, for example, in the region of a vehicle windshield 60 and has one or more electrically operable fans 62 which supply heated air to further regions of the vehicle interior 38 from the region of the vehicle 10 or of the vehicle interior 38 in which the air present therein is primarily heated.

In order to supply the air supply unit 58 with electrical energy, it can be connected to an electrical energy store associated with the vehicle heater 18. If the electrical energy store (as shown in fig. 1) is arranged in the interior of the vehicle 10, the electrical coupling of the air delivery unit 58 to the electrical energy store takes place directly via the electrical lines to be connected to the electrical energy store. As shown in fig. 12, if such an electrical energy store is arranged in the heating receiving container 14, i.e. outside the vehicle 10, the electrical connection between the electrical energy store and the air conveying unit 58 may comprise a wireless coupling path device 64, for example positioned in the region of the windshield. Electrical energy may be transmitted, for example, via the wireless link path device 64 via electromagnetic interaction between a wiring region located outside the vehicle interior 38 and a wiring region located inside the vehicle interior 38.

The vehicle heating system described above allows operation substantially independently of the vehicle to be heated or of the system region of such a vehicle. The vehicle heating system or the system region thereof is substantially independent of the system region of the vehicle, for example in order to supply the vehicle heating system with electrical energy or fuel or to supply information about the thermal state of the vehicle from the electrical system of the vehicle to the vehicle heating system. This allows the use of such a vehicle heating system in combination with different vehicles. Furthermore, a loading of an energy store provided in the vehicle and a consumption of fuel provided for the operation of the vehicle are avoided. Due to the vehicle-independent ensured operability of the vehicle heating system, the latter can be used not only in different vehicles, but in particular also in conjunction with vehicles which are to be operated electrically (which generally have no fuel tank).
