Abstract: A refrigerated merchandiser including a case defining a product display area and including an air inlet and an air outlet in communication with the product display area to form an air curtain across a front of the product display area. The refrigerated merchandiser also includes a shelf that is coupled to the case within the product display area. The shelf includes insulation between a top and a bottom of the shelf, and a passive heat exchanger that has a heat pipe embedded in the shelf within the insulation and that extends from a front of the shelf to a back of the shelf. Ambient air infiltrating the air curtain initiates passive heat transfer within the plurality of heat tubes.
