An integral heat exchanger with a condenser and an oil cooler is provided to reduce a pressure drop and to increase heat exchange efficiency by varying the hydraulic diameter of each tube of a condensing section, a supercooling section and an oil cooler section. An integral heat exchanger(100) with a condenser and an oil cooler comprises a pair of header tanks(110) arranged at regular intervals and placed parallel to each other, a condensing section(103) coupled to a pair of the header tanks to condense refrigerants, a supercooling section(104) supercooling the condensed refrigerants, plural tubes(113,114,115) forming an oil cooler section(105) cooling down oil, and heat radiating fins(116) placed among the tubes to facilitate heat exchange. The integral heat exchanger reduces a pressure drop and increases heat exchange efficiency by varying the hydraulic diameter of each tube forming the condensing section, the supercooling section and the oil cooler section. |
