A heat transfer device for cooling a fluid has powered means for moving the fluid to create a primary fluid flow, a heat exchanger, and direction controlling surfaces for directing the primary fluid flow toward and through a first portion of the heat exchanger, thereby cooling the fluid flow. The direction controlling surfaces then split the primary fluid flow into a first and second subsidiary fluid flow, and direct the second subsidiary fluid flow through a second portion of the heat exchanger, thereby cooling it to a second temperature which is lower than the first temperature.

A refrigerated cooler for containing a product, comprising: a cabinet having a partition defining a heat transfer chamber and a thermally insulated product storage chamber having an access opening providing fluid communication between said product storage chamber and ambient air; powered means mounted near an inlet opening defined by said partition for moving air to create a primary fluid flow from said product storage chamber into said heat transfer chamber; a heat exchanger disposed in said heat transfer chamber; direction controlling means for directing said primary fluid flow toward and through a first portion of said heat exchanger, thereby cooling said primary fluid flow to a first temperature, said direction controlling means adapted to split said primary fluid flow into first and second subsidiary fluid flows, and to direct said first subsidiary fluid flow through a first outlet defined by said partition into said product storage chamber, and to direct said second subsidiary fluid flow through a second portion of said heat exchanger, thereby cooling said second subsidiary fluid flow to a second temperature, said direction controlling means adapted to direct said second subsidiary fluid flow through a second outlet defined by said partition into said product storage chamber; baffle means in said heat transfer chamber for maintaining said primary fluid flow and said second subsidiary fluid flow separate; and flow means for directing said second subsidiary fluid flow in an air curtain across said access opening; wherein said first temperature is greater than said second temperature, thereby more evenly cooling said chamber.
