A conduction cooled power supply is designed with a flat baseplate, through which any heat generated by the components of the power supply can be conducted away, as opposed to a convection cooled power supply, where the heat radiates into the air around the power supply. Efficient conduction cooling is usually achieved by mounting the power supply inside the outer wall of a metal equipment case, in a position that allows heat transfer through the case to the surroundings, this may be enhanced by ribs or a heatsink on the outside of the case.The advantages are that it allows the case to be sealed to prevent ingress of contaminants, also it eliminates the need for fan assisted cooling with its noise, energy consumption and servicing requirements.Conduction cooled DC-DC converters and AC-DC power supplies are available from XP Power to suit a multitude of applications.
