An automotive heat exchanging system has a heat exchanger comprising a condenser and a radiator, an electric fan located in the front of an engine and an automatic transmission. A shroud is attached to and covers peripheral portions of the electric fan and the heat exchanger to prevent air from bypassing the shutter. The shroud forms an air passage inside of it for allowing airflow through the heat exchanger to flow toward the automatic transmission. A shutter is disposed in the shroud and attached at a periphery of the shroud. The shutter is controlled to open and close the air passage by a controller based on oil temperature.

In a cooling system for a water-cooled internal combustion engine and a control method applicable to the control system, a pump to circulate a coolant to the water-cooled engine and a heat exchanger is drivingly controlled in such a manner that, when a temperature of the coolant detected by a temperature detector indicates a value higher than a predetermined target temperature, a flow state of the coolant circulated within a plurality of tubes arranged within the heat exchanger falls within a predetermined range including at least one of a transition range between a laminar flow range and a turbulence flow range and a part of the turbulence flow range which is placed in vicinity to the transition range (corresponding to 1800 through 6000 in Reynolds number) and the coolant is circulated through the pump into the water-cooled engine and the heat exchanger by a predetermined flow quantity.

A connecting structure for connecting a radiator having a reinforcement member and a condenser having a bracket is provided. The structure includes a connecting member having a spacer portion and a holding portion integrally formed on opposite sides of a notch. The spacer portion is fittingly inserted into the reinforcement member, and a folded portion of the reinforcement member and the condenser bracket are inserted into the notch. A bolt is inserted through the reinforcement member, the spacer portion, the bracket and the holding portion and a nut is screwed onto a tip of the bolt for clamping the radiator and the condenser together.
