Abstract


Heat pipe heat exchangers (HPHE) can be used to enhance dehumidification and increase the cooling capabilities of heating, ventilation and air conditioning (HVAC) systems. A C-shape HPHE is a passive system consisting of an array of heat pipes. This paper investigates the thermal performance of a R410A-filled C-shape thermosyphon under various operating conditions. The effects of the angles of slope and power inputs are reported with no difference between slope angles of 60-90˚ and a decrease in performance at 30˚. A model based on the vertical thermosyphon showed that the thermal resistances of the C-shape and vertical thermosyphon were comparable.
