A fan assembly is supported in the main housing assembly near the front housing end. A solid coolant retaining assembly, for retaining a block of water ice, is supported in the main housing assembly and is located between the fan assembly and the rear housing end. The solid coolant retaining assembly includes a plurality of retainer air channels, and an access door is connected to the main housing assembly for allowing access to the solid coolant retaining assembly through the main housing assembly. Preferably, the main housing assembly further includes housing air channels located on side portions of the main housing assembly. A drainage receptacle is connected to the solid coolant retaining assembly for receiving the liquid melt from the ice.
