Abstract
The cooling apparatus comprises an air-cooled heat exchanger, a number of louvres to control a cooling air flow passing the heat exchanger, a mechanism for operating the louvres and an actuator for actuating the operating mechanism according to the temperature of the heat exchanger. The actuator comprises a bar(26) having a first end (26A) and a second end(26B) and is of a material having a considerably lower thermal expansion coefficient than that of the heat exchanger(1). The heat exchanger comprises upward finned tubes(2). The bar is attached by its first end substantially at the first end(1A) of the heat exchanger. There is a member for controlling the position of the operating mechanism(13,14) in dependence on a difference in displacements of the second end of the bar and the second end(1B) of the heat exchanger due to the thermal expansion of the bar and that of the heat exchanger.
