The bidirectional wave water filling material features a sheet structure composed of sine waves and trapezoidal waves with staggered straight wave segments, which enhances the turbulence and downward flow velocity of air and water, improving the heat dissipation characteristics of the material. By increasing the open area, it ensures the smooth passage of rubber balls and enhances resistance to mud and scale blockage. Its thermal performance and resistance characteristics are comparable to imported composite waves, providing excellent cooling efficiency.
