PURPOSE: A tritube heat exchange for an evaporator is provided to improve the efficiency of heat transmission by increasing passage of air passing through refrigerant tubes. CONSTITUTION: In a tritube heat exchange for an evaporator including three tubes of a right refrigerant tube(1b') and a left refrigerant tube(1a') wherein a refrigerant flows, and a defrosting tube(1c) for defrosting, and pins(2) for connecting respective tubes, the pins includes a plurality of louvers formed at a right angle to flow direction of air, and the refrigerant tubes are elliptically formed to have large contacting area with air. The refrigerant tubes are longitudinally formed based on the arrangement direction of the tubes, and the ration of long shaft to short shaft is 1.5 to 1.
