An object of the invention is to provide a heat exchanger (radiator) or a cooling module having the radiator and a condenser, which has a higher rigidity against vibration in the vertical direction. To the end, the radiator or the cooling module is mounted to a vehicle by mounting brackets, which are fixed to the radiator tanks at their vertical ends. The mounting brackets have mounting pins, with which the radiator or the cooling module is mounted to the vehicle.

An attachment portion between an upper member () and a radiator () is constructed so as to be displaced in a longitudinal direction of the upper member () when an impact force is applied to the upper member () by constructing a mount cushion () so as to be deformed easily in a longer diameter direction thereof. By this structure, when an impact force is applied to the upper member () from a front side of a vehicle, as it is not that the radiator () and the upper member () are deformed together but that the upper member () is deformed prior to the radiator (), a bending rigidity to an impact force becomes smaller than a conventional case. Consequently, since the upper member is allowed to be deformed easily at the time of collision without largely reducing the mechanical strength of the upper member (), compatibility between the requirements of protection of pedestrians and sufficient strength of the upper member () can be ensured.

Front-end structure of vehicle

A carrier () is secured to a vehicle front end portion via a bracket () secured to side members () and a bumper reinforcement (). The connecting portions of the carrier () to the bracket () are deviated from the side members () when viewed from the front side of a vehicle. The bracket () is provided with a reinforcing member portion () to connect the left and right side members (). Accordingly, the action of a large impact force on the carrier () can be prevented because only a collision force from the bumper reinforcement () acts on the carrier () and no reaction force, from the side members, acts on the carrier, when a collision occurs. Therefore, the carrier () can be prevented from being broken when a light collision occurs because the attaching portions of the carrier () are seldom broken. The rigidity of a vehicle body can be increased by the reinforcing member portion (), and the necessary rigidity of the carrier () can be reduced. Thus, the weight of the carrier () can be reduced.

Vehicle front end structure

A front-end structure comprising a panel body ( ) to which a center member ( ), being fixed to a body of a vehicle at a front end of the vehicle and supporting, at least, a driving engine (E/G), is joined, wherein the panel body ( ) is molded out of aluminum by die-casting and a joining section ( ) of the panel body ( ) to which the center member ( ) is joined has a mechanical strength higher than that of any other sections of the panel body ( ) near the joining section ( ) except the joining section ( ).

Front-end structure of a vehicle

A vent line ( ) for establishing communication between the interior of headlamps ( ) and at least a blower ( ) is formed integrally with a front end panel ( ). The vent line ( ) makes up a duct member ( ) leading from each of the headlamps ( ) to the blower ( ). A light controller ( ) is assembled by being fixed on the panel ( ) in such a manner as to be located at the air inlet ( ) of the duct member ( ) (vent line ( )).

When a load given to the engine is less than a predetermined value, the outside air suction port is closed and only inside air is supplied to the engine , and the valve is opened so as to supply warm water to the heater . When the load given to the engine is not less than the predetermined value and the temperature of air outside the engine compartment is lower than a predetermined value, the inside air suction port is closed and only outside air is supplied to the engine , and the valve is closed so that the supply of warm water to the heater is stopped.

Internal combustion engine device

The radiating section ( ) of the control unit ( ) is exposed to air flowing in the intake path ( ) formed in the panel body ( ). Due to the foregoing, it is possible to cool the control unit ( ) by air (about 35&deg; C.), the temperature of which is lower than the temperature of air (about 60&deg; C.) which has passed through the condenser ( ) and the radiator ( ). Accordingly, the cooling effect (cooling capacity) can be enhanced. Therefore, the size of the radiating section ( ) can be reduced, and the structure of the control unit ( ) (the mounting structure of the electronic parts ( )) can be simplified. As a result, the manufacturing cost of the control unit ( ) can be reduced.
