Boiling refrigerant‐type panel cooler (refrigerant circulation and cooling performance)

We have developed a new compact boiling refrigerant type panel cooler. It is a closed two-phase loop thermosiphon constructed with heat exchanger cores for an automobile air conditioning system. We confirmed higher performance of the natural refrigerant circulation type and tried to optimize the size of the refrigerant path in the boiling core by observing the internal refrigerant flow and successfully achieved much higher cooling performance. © 2004 Wiley Periodicals, Inc.
