The bidirectional wave water distribution packing features a sheet profile composed of staggered sinusoidal and trapezoidal waves forming straight wave segments. This design enhances turbulent flow and downward velocity of air-water interaction, improving heat dissipation characteristics. With increased open area, it ensures smooth passage of rubber balls and enhances resistance to fouling and clogging. Its thermal performance and resistance characteristics are comparable to imported composite wave designs, delivering effective cooling performance.
