Abstract
Resistor bank cooling apparatus 1 has an enclosure 2 surrounding a resistor bank 4. At least one first vane 6 directs into the enclosure 2 air flowing past an open side 12 thereof, which open side 12 is not a side facing the direction from which the air flowing past the enclosure 2 flows. The resistor bank 4 has a resistor element 22 which functions as at least one airflow directing baffle. The or each first vane 6 and the or each baffle are each disposed thereby to create an air flow through the enclosure 2 which achieves a sufficiently even cooling of the resistor bank 4. At least one second vane 60 to the side of the or each first vane 6 remote from the open side 12 captures and deflects into the enclosure 2 air which ‘bounces off’ the closed facing sides.
Claims17
Resistor bank cooling apparatus comprising an enclosure surrounding a resistor bank, air deflecting means for deflecting into the enclosure air flowing past an open side thereof, which open side is not a side facing the direction from which the air flowing past the enclosure flows, wherein the resistor bank has a resistor element which functions as at least one air flow directing baffle and wherein the air deflecting means and the or each baffle are each disposed thereby to create an air flow through the enclosure which achieves a sufficiently even cooling of the resistor bank.
