Abstract

A radiator 1 comprises a radiator block 2 and water tanks 3, at least one of the tanks 3 having a round or oval cutout 5 which serves as an inlet opening for combustion air. A connector 6 attaches the cutout 5 to an intake line for feeding the combustion air to an engine. This arrangement results in a simpler construction and fitting and reduces problems of space which allows a larger area for the fitting of attachment elements 7, thereby providing stable fixing of the radiator 1. The attachment elements also enables the radiator to serve, at the same time, as a supporting part for an air-conditioning condenser, a charge-air heat exchanger and/or an extractor fan. The water tank 3 is provided with connection 8 for cooling the transmission oil and connection 9 for venting the radiator 1.

Description

r c eh 1 2319758 Device for feeding combustion air to the engine of a
motor vehicle The invention relates to a device for feeding combustion air to the engine of a motor vehicle having a radiator which has a radiator block and water tanks provided with cooling-water connections.
Radiators of this type are generally known. The front area of a motor vehicle is often sealed off to prevent the entry of the airstream. Only the radiator is exposed to the air flow. Furthermore, an intake opening is left exposed for the feeding of combustion air to the internal combustion engine. From the intake opening, a cooling-air scoop or an intake duct leads to the engine (see DE 41 23 038 A l and DE 39 30 076 Cl). In this case, the intake duct is located to the side of the radiator and has a separate attachment.
Owing to the arrangement of the intake duct or ducts to the side of the radiator, there is only limited space available for its/their attachment. This space limitation also has a negative effect on the size of the water tanks. Furthermore, owing to the separate attachment of the radiator and the intake duct, a correspondingly great outlay for fitting and a correspondingly great outlay for removal in order to carry out repairs are also required.
The present invention therefore seeks to provide a device of the type mentioned at the beginning, which is simple in terms of construction and fitting and reduces problems of space.
According to the invention, there is provided a device for feeding combustion air to the engine of a motor vehicle having a radiator which has a radiator block and water tanks provided with cooling-water connections, and having an intake line for the combustion air, wherein at least one of the water tanks is provided with an inlet opening for the intake line.
According to the invention, the inlet opening for the intake line is now integrated in one or both water tanks, which are generally arranged to the side of the radiator block. To achieve this, it is merely necessary to provide the water tank or each of the water tanks with an appropriate cutout, e.g. in the form of a round or oval opening. The opening, which may be provided with a connector on the rear side of the 2 water tank, is then adjoined in a simple manner by the intake line for the combustion air. This means that, according to the invention, not only are there now fewer parts, for instance the air scoop and attachment material for it are no longer required, but the outlay for fitting and removal purposes is also less.
Moreover, the surrounding seal around the device can be of a far simpler design. To attach the radiator by means of the water tanks, because there is a larger attachment area, the said water tanks can likewise be configured to be larger and thus more stable. This means that a far larger and thus more secure basis is provided for the attachment of the device. Furthermore, with the same construction space, there is a far larger cross-sectional area for the intake because of the intake line no longer being arranged to the side as in the prior art in conjunction with no safety distance being required between the radiator and the known air scoop or intake line. The same also applies to the dimensions of the water tanks.
Advantageous further developments and refinements of the invention emerge from the exemplary embodiment described below with reference to the drawing, in which:
Figure 1 shows a partial front view of the device according to the invention in a perspective illustration; Figure 2 shows a partial rear view of the device in a perspective illustration.
The device for cooling and for feeding combustion air to the engine (not illustrated) of a motor vehicle has a radiator 1 with a radiator block 2 and two water tanks 3, attached laterally, with cooling-water connections (not illustrated). In each case between the radiator block 2 and the water tanks 3 there is also a tube plate 4, in which the tubes of the radiator system are attached and onto which the water tanks 3 are flanged. In the upper region of one or both water tanks 3 there is a cutout in the form of an oval opening 5. The opening 5 serves as an inlet opening for combustion air. The opening 5 is configured as a through-bore and is provided on its rear side, that is to say on the side facing into the vehicle, with a connector 6 for connection to an intake line (not illustrated) for feeding combustion air to the engine.
As can be seen from the two figures, the integration of the inlet opening into the upper region of the water tank 3 results in the further advantage of a far larger area for mounting attachment elements 7 which are illustrated only in principle in the 3 drawing. On the rear side, the water tank 3 is provided with connections 8 for cooling the transmission oil and 9 for venting the radiator.
The possibility of stable attachment of the radiator 1 by means of the attachment elements 7 enables the device also to serve, at the same time, as a supporting part for an air-conditioning condenser, a charge-air heat exchanger andlor an extractor fan (not illustrated).
As can be seen from the drawing, a very simple surrounding seal can also be achieved, by virtue of the shape of the radiator with the integrated cold-air scoop or inlet opening.
