ABSTRACT:
A portable cooling chest having a durable outer shell and an inner liner, each with bottom and side wall members, includes a unitary middle liner arranged in proximity to the bottom and side wall members of the outer shell to define an insulating compartment and in proximity to the bottom and side wall members of the inner liner to define a sealed cavity circumscribing the inner liner and containing eutectic fluid and immersed heat exchange coils. The heat exchange coils, coupled through a quick connect/disconnect means to the refrigerant of an automobile refrigeration system, circulate chilled refrigerant to chill and freeze the eutectic fluid within the sealed cavity and cool the interior space of the cooling chest.
