HEAT TRANSFER PIPE OF EVAPORATOR

摘要

PURPOSE: A heat transfer pipe of evaporator is provided to minimize whole size of the evaporator and improve heat exchanging performance with air. CONSTITUTION: A heat transfer pipe(12) is formed to have various diameters according to flowing direction of air. The diameter of the heat transfer pipe gradually increases from an inlet side row(12a), which contacts with air most, to an outlet side row(12b) with respect to the flowing direction of air to make air flow smooth to reduce longitudinal length of an evaporator. Vortex or air passing the evaporator increases to improve contact between the air and the heat transfer pipe to improve heat exchanging performance of the evaporator.
