PURPOSE: A condenser fan protection grille for heat exchanger is provided to achieve an improved condensation efficiency and heat exchange efficiency by improving the shape of blade of the grille to generate vortex flow. CONSTITUTION: A heat exchanger comprises a condenser(1), a condenser fan(2), a condenser protecting grille(3), an evaporator and a compressor. The condenser protecting grille has blades(4) each of which is formed to have a directivity to allow air to rise in a vertical direction. Each of blades of the grille allows the grille to have different angle at the central portion and end portion of the grille, respectively. The blade is formed into a curve having a predetermined inclination so as to allow the air flow generated from the condenser fan to be turned into a vortex flow when the air passes through the condenser protection grille. Thus, the air flow generated from the condenser fan is prevented from flowing out between the grille and condenser fan.
