Driven by the drive motor 2, the conveying roller 3 rotates at a constant speed, driving the sheet material to move in a directional manner. When the conveying roller 3 rotates, the upper part of the conveying roller 3 contacts the sheet material to absorb heat, while the lower part of the conveying roller 3 contacts the liquid water to form a thin film on the surface and conduct heat for cooling. The densely arranged conveying rollers 3 at the front can improve the heat dissipation process. The support contact area at the bottom of the plate reduces contact pressure and prevents deformation damage to the plate. It also achieves rapid cooling of the lower part of the plate through conduction. During conveying, when the plate tends to deviate, the side of the deviated plate contacts the inclined side of the limiting side seat 4. The inclined side of the limiting side seat 4 guides the plate back to its original position, ensuring stable conveying of the plate. The plate is stably conveyed and discharged by the conveying roller 3. During operation, the water pump 9 works to transport the water in the guide conveying seat 1 into the interior of the heat dissipation plate seat structure. The water flows through the U-shaped liquid guide groove 13 and conducts heat to the heat dissipation base plate 11 through contact conduction. The heat is then efficiently dissipated through the heat dissipation fins 14 at the bottom of the heat dissipation base plate 11, completing the heat dissipation and cooling of the water.
