<p>PROBLEM TO BE SOLVED: To provide a membrane body in which the development of crack due to fatigue breakage caused by heat stress can be restrained, and to provide a skirt cooler in which the service life of the equipment can be improved by providing this membrane body. SOLUTION: In the membrane body welding many tubes for cooling water in almost parallel state through fins, in the case of using D (mm) for outer diameter of the tube, T (mm) for thickness of the fin and L (mm) for width of the fin, a shape parameter D.T/L is 20-30. Then, the D.T/L is desirable to be 23-27.</p> |
