Cold storage heat exchanger

Abstract

Provided is a cold storage heat exchanger, and more particularly, a cold storage heat exchanger capable of increasing cooling comfort for a user and minimizing energy and time consumed upon performing a re-cooling by discharging cooled air stored in a cold storage tube upon operating an air conditioner of a vehicle even in the case in which an engine is stopped because the cold storage tube is provided between refrigerant tubes in an evaporator used in an air conditioner apparatus of the vehicle to thereby prevent a rapid increase in an interior temperature of the vehicle.
