Abstract
A cooling system is provided for compartments containing a heat generating apparatus, such as solid state variable speed constant frequency system, whose functionality is essential and whose cooling needs vary significantly during use. A main coolant channel is used to provide cooling to the heat generating apparatus under normal operating conditions. During an overtemperature condition; an auxiliary coolant channel provides additional coolant to the heat generating apparatus. Both of the channels are partially disposed within the heat generating apparatus, and they are both completely separate and free of fluid communication with each other. Each channel also contains a pump, such as a fan, for applying a motive force necessary to deliver the coolant to the heat generating apparatus. The pump contained in the main coolant channel is operated constantly, while the pump contained in the auxiliary coolant channel is selectively introduced by a cooling system controller which is responsive to the temperature conditions of the heat generating apparatus.
