Abstract

The engine (6) of a motor vehicle is enclosed at least partially in a compartment (1) including a bonnet (2). The front grille (3) of the vehicle body is disposed ahead of a heat exchanger in the form of a radiator (4) disposed ahead of the engine (6) and a cooling fan (5) is disposed between the radiator (4) and the engine (6). The space between the radiator (4) and the fan (5) is defined by a frame (12) connected to a fan shroud (10) by a bellows (11) and a baffle plate (8) is disposed between the fan (5) and the engine (6). The baffle plate (8) is connected to the fan shroud (10) at the top and on each side by a turned-over portion (9) and a venturi-shaped outlet is provided at the bottom of the shroud through which cooling air can flow out and over the walls of the engine oil sump. Means may be provided by which the rotation of the fan (5) and hence the cooling effect can be controlled. The arrangement according to the invention suppresses engine noise. <IMAGE>

Description

SPECIFICATION A cooling arrangement for the engine compartment of a motor vehicle having a partially enclosed engine The invention relates to a cooling arrangement for the engine compartment of a motor vehicle having a partially enclosed engine and a heat exchanger or radiator, which is mounted in front of the engine and through which cooling air flows when the vehicle is in motion, and having a cooling air fan a arranged between the said radiator and the engine.
An engine compartment having a cooling fan with an enclosing frame connected by a bellows to the radiator has been proposed in German PatentApplication 29 24 568.9. In view of existing or proposed statutory regulations it is necessary for engine noises to be increasingly damped and consequently for the engine situated in the engine compartment of a motor vehicle to be increasingly enclosed.
Hitherto, engines had only been enclosed to such an extent that a stream of cooling air around the engine was still possible. However, it has been found that with this type of enclosure there is still a tendency to allow too much engine noise to be transmitted to the outside from the engine compartment.
The invention seeks to provide an improved enclosure of the engine and the further suppression of engine noise.
According to the invention, there is provided a cooling arrangement for the engine compartment of a motor vehicle having a partially enclosed engine and a heat exchanger which is mounted in front of the engine and through which a motion - induced air stream flows, and including a fan enclosed by a shroud disposed between the radiator and the engine, the fan shroud being connected to the heat exchanger by a flexible bellows and a frame, wherein a baffle plate which is connected to and supported by only the fan shroud by means of a turned-over portion, is arranged between the fan and the engine.
The turned-over portion of the baffle extends along three sides of the baffle plate and leaves a clear gap at the bottom which widens like a venturi and through which the air flowing past the fan can flow downwards and then rearwards. The air, after emerging from the gap, steams rearwards and will then flow around the oil sump and, consequently, still also serve to cool the outer walls thereof.
The proportion of engine cooling which was hitherto undertaken by air still able to flowthrough the engine enclosure must now be effected in a different manner, i.e. the dissipation of heat which was hitherto effected by air streaming through the enclosure must now be ensured in a different manner. For this purpose it is provided that the cooling of the engine is transferred substantially from the enclosure into the radiator and the cooling power or capacity is regulated by a temperature sensor which is mounted on the engine and which can control the rotational speed of the fan for example by a coupling and thus increases the efficiency of the radiator.
Moreover, it can also be provided that the cooling capacity of the actual radiator and fan be increased in order to enable heat to be dissipated to a greater extent in this manner.
An embodiment of the invention will now be described by way of example and with reference to the accompanying drawing which shows a diagrammatic view of the engine compartment 1 of a motor vehicle having a bonnet 2 and a radiator grille 3. The radiator4 is arranged behind the radiator grille 3 in the conventional manner. The radiator is followed in the known manner by the fan 5 which is situated in front of the engine 6 and is driven thereby through a V-belt arrangement 7.
For the purpose of sound damping, a baffle plate 8 which supports the fan-enclosing shroud 10 by way of a turned-over portion 9 is now arranged in front of the engine 6 in the manner according to the invention. The fan shroud 10 is connected by a flexible bellows 11 to a radiator frame 12 which is in turn attached to the radiator 4.
The turned-over portion 9 surrounds the baffle plate on three sides, i.e. it is connected thereto at the top and on each side and, accordingly, leaves a clear gap 13 at the bottom the cross-section of which widens like a venturi and through which the air can flow downwards. After being deflected by the headwind, this air stream also flows rearwards. The baffle plate 8 is extended downwards into a part 14 of the engine enclosure which extends closely past the oil sump 15 so that the air stream also flows around and thus cools the exterior of the sump.
In contrast to the previous system of cooling the engine by means of an air stream flowing directly around the engine, the cooling of the substatially enclosed engine 6 is transferred to a greater degree from the engine enclosure 14 to the radiator 4 which must produce a greater cooling capacity than before.
The cooling capacity is regulated by a temperature sensor (not show) which is mounted on the engine 6 and which can also control the rotational speed or the cut-in or cut-out of a drive means for the fan 5.
