Abstract: The present invention relates to a heat exchanger plate, more particularly, in which a number of beads for imparting turbulence to refrigerant flowing through a channel of a plate are formed streamlined and guide beads arre formed in refrigerant distributing sections in order to reduce the pressure drop of refrigerant while realizing uniform refrigerant distribution. In the heat exchanger plate of a tube including a tank communicating with a channel, a number of first beads so arrayed in the plate that opposed sides are coupled to each other to impart turbulence to refrigerant flowing through the channel and refrigerant distributing sections provided in inlet and outlet sides of the channel and divided by at least one second bead to have a plurality of paths, the first beads are formed streamlined and satisfy an equation of 0.35?W/L?0.75, wherein W is the width and L is the length.
