Abstract
A heat exchanger coil for a heat exchanger assembly that has a housing defining at least one airflow path and that is adapted to receive an airflow for heating or cooling refrigerant in the heat exchanger coil. The heat exchanger coil includes a substantially cylindrical tube for receiving the refrigerant, and at least one plate coupled to the tube and oriented so that the direction of the airflow adapted to enter the housing is non-orthogonal relative to the orientation of the plate.
Claims37
A heat exchanger coil for a heat exchanger assembly having a housing defining at least one airflow path and adapted to receive an airflow for heating or cooling refrigerant in the heat exchanger coil, the heat exchanger coil comprising:
- a substantially cylindrical tube for receiving the refrigerant;
- and
- at least one plate coupled to and extending along a substantial length of the tube, the plate oriented so that the direction of the airflow adapted to enter the housing is non-orthogonal relative to the orientation of the plate.
A heat exchanger assembly comprising:
- a housing adapted to receive an airflow and defining at least one airflow path therethrough;
- an inlet manifold including an inlet port for receiving refrigerant;
- an outlet manifold including an outlet port for discharging the refrigerant;
- and
- a heat exchanger coil coupled to and extending between the inlet manifold and the outlet manifold, the heat exchanger coil including a plurality of coil sections spaced apart from each other, each of the coil sections having a substantially cylindrical tube and at least one plate coupled to and extending along a substantial length of the tube, each plate oriented so that the direction of the airflow adapted to enter the housing is non-orthogonal relative to the orientation of the plate.
A refrigerated merchandiser comprising:
- a case defining a product display area and including a rear wall partially defining a rear passageway, the case further including an accessible refrigeration compartment;
- a fan assembly including a fan positioned in at least one of the rear passageway and the refrigeration compartment for generating an airflow;
- and
- a heat exchanger assembly defining at least one airflow path and including a housing positioned to receive the airflow generated by the fan, an inlet manifold for receiving refrigerant, an outlet manifold for discharging the refrigerant, and a heat exchanger coil coupled to and extending between the inlet manifold and the outlet manifold and having a plurality of coil sections spaced apart from each other, each of the coil sections having a substantially cylindrical tube and at least one plate coupled to and extending along a substantial length of the tube, each plate oriented so that the direction of the airflow adapted to enter the housing is non-orthogonal relative to the orientation of the plate.
