Abstract
An electronic apparatus has a heat-exchanger within a housing exchanges heat between internal and external fluids without direct contact between the fluids. The internal fluid circulates within the housing and the external fluid is received external from the housing and output external from the housing 120. The housing includes is a heater; impellers; a controller for controlling the heater and the flow of fluids through the heat-exchanger; and temperature and humidity sensors. The controller receives temperature and humidity data from the sensors; processes the data to indicate a current dew point within the housing; and compares the current dew point with a current location temperature at or adjacent the heat-exchanger. If the current location temperature is at or below the current dew point, the controller raises the temperature at at least one location on the heat-exchanger and/or activates the heat source to raise the temperature.
