ABSTRACT:
A cooler chest has an open top which may be covered or uncovered by removable doors. A plurality of downwardly directed jets around the upper periphery of the chest forces cold air into the bottom of the chest, thereby displacing warm air from the chest and into the ambient atmosphere. The cold air in the chest is drawn through an evaporator coil for further cooling and then returned to the jets at the upper periphery for a continued cooling of the chest.
