    • PURPOSE: A cooling airfoil with a spray mode, which is formed with concavities and convexities which are downwardly inclined, and a cooling device thereof are provided to efficiently perform cooling of a second fluid by forming concavities and convexities on the inner wall of the cooling airfoil. CONSTITUTION: A cooling airfoil with a spray mode, which is formed with concavities and convexities which are downwardly inclined, includes a case(100) and a spray(110). The case is formed with an inlet hole(101), an outlet hole(102), and an inner space(103) for a second fluid, which is cooled by exchanging heat with a first fluid with low temperature, to pass through. The spray is mounted on the inlet hole of the case, and sprays the second fluid into the inner space. Multiple concavities and convexities(120) are formed to be downwardly inclined on the inside of the case to extend a contact area which is contacted with the sprayed second fluid.
