DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention pertains to an arrangement of a heater in a vehicle.
BACKGROUND OF THE INVENTION
Heaters in a motor vehicle are known to be accommodated protected in the engine compartment or the interior space and require a relatively large space for installation, which could be used for other purposes.
SUMMARY AND OBJECTS OF THE INVENTION
The primary object of the present invention is to provide a heater arrangement in a vehicle, which saves installation space in the interior area of a vehicle with comparatively simple means without compromising the heat output.
According to the invention, an arrangement of a heater in a vehicle is provided with a heater provided with a water protection device. The heater is fastened on the underside of the vehicle bottom.
The essence of the present invention is to fasten the heater arrangement on the underside of the vehicle bottom, wherein the heater has a water protection device. A previously unused installation site is thus utilized on the vehicle. More installation space is correspondingly left for other assembly units of the vehicle in the engine compartment or the interior space. One particular advantage of the present invention is that the present invention makes it possible to retrofit a vehicle with a heater in a simple manner. This also applies, in particular, to the later installation of the heater in a vehicle, which cannot be retrofitted according to the state of the art, namely, in the case of a vehicle that inherently has no more place for an additional heater in the engine compartment or in the interior space of the vehicle. The new installation area under the bottom of the vehicle, mostly between the vehicle axles, is also largely protected from damage by these axles.
According to one advantageous variant of the present invention, the water protection device is a solid protective container, which can be fastened to the underside of the vehicle bottom, wherein the heater is accommodated in the protective container. A solid protective container offers protection not only against water, but also against mechanical effects, e.g., falling, thrown or flying rocks.
The solid protective container may be a sheet-metal part, a plastic part or a casting, especially a diecast aluminum part, and it can be manufactured in a simple manner.
The heater is preferably accommodated in the protective container in a positive-locking manner, and the protective container may have inner guide ribs.
The heater may be fastened in the protective container by fastening elements, especially clamps or thumb screws or be additionally secured in the case of positive-locking mounting.
The protective container preferably has integrated fastening support points for fastening to the underside of the vehicle bottom. In the case of a diecast aluminum container, the support points, of which there are preferably three, are cast integrally. The mounting of the container on the vehicle is simplified by the integrated support points.
The protective container preferably has a lateral sealing cover, which can be detachably fastened, especially screwed, to a preferably trough-shaped base part of the protective container. With the lateral sealing cover removed, a heater can consequently be introduced into and removed from the interior of the container and maintenance can be performed on it from the vehicle side in a simple manner.
The cover is advantageously designed as a flat cover for reasons of manufacturing and handling.
The cover preferably has a circumferential edge for better sealing of the container against dirt and water.
Connecting branches or passage openings for connection lines of the heater, e.g., for the heater/cooling medium circuit to an internal combustion engine, for fuel supply to the heater and/or the electrical operation of the heater during the start-up phase of a motor vehicle and for an electrical control of the heater are preferably provided in the cover.
The base part of the protective container may also have connecting branches or passag
