A INTEGRATED-TYPE HEAT EXCHANGER

摘要

An integrated heat exchanger is provided to reduce difference of cooling efficiency or mechanical efficiency caused by difference of characteristics(viscosity, temperature, pressure, and others) between refrigerant and oil by adjusting size of a tube. An integrated heat exchanger comprises a first core and a second core. The first core is located in an upper side and has a portion for allowing first heat exchanger fluid to be flown. The second core is located in a lower side and has a portion for allowing second heat exchanger fluid to be flown. Ventilation resistance of the second core is formed to be less than or the same as that of the ventilation resistance of the first core.
