Abstract
The disclosed technology includes an evaporator having a plurality of sidewalls arranged to define an internal cavity and a top plate covering the internal cavity. At least one of the sidewalls can include a plurality of refrigerant channels such that at least one of the sidewalls can function as a heat exchanger. Each of the refrigerant channels can be attached to a refrigerant inlet and a refrigerant outlet at an angle, such that each refrigerant channel is angled. The angled refrigerant channels can facilitate directing ambient air across the refrigerant channels and fins and to the internal cavity. The angled refrigerant channels can further provide a flow path for accumulated moisture and/or condensate on the exterior surfaces of the refrigerant channels and/or fins to shed, thereby minimizing the potential for freezing.
