As shown in fig. 1, when an optical lens with poor heat resistance is heated, in order to avoid the situation that the lens is softened or damaged due to an excessively high air temperature, the heating temperature of the optical lens needs to be regulated and controlled, a horizontal and fixed connection at the top inside the box 10 is used for separating a partition plate 12 and a heat exchange plate 13 inside the box 10, the partition plate 12 is located below the heat exchange plate 13, heat exchange tubes 14 are uniformly connected between the partition plate 12 and the heat exchange plate 13, two ends of each heat exchange tube 14 respectively penetrate through the partition plate 12 and the heat exchange plate 13, each heat exchange tube 14 is hollow, heat conduction liquid is contained between the partition plate 12 and the heat exchange plate 13, the heating rod 15 is soaked in the heat conduction liquid, and a liquid filling opening 17 is formed in the outer wall of the box 10.

When the optical lens is a resin lens, the thermal deformation temperature of the resin lens is 140 ℃, the heat conducting liquid is water, the boiling point is 100 ℃, and the heating temperature of the resin lens is limited to be lower than the deformation temperature by the water, so that the optical lens is prevented from being heated to cause deformation; air blown out by a fan 11 flows below a partition plate 12 through a heat exchange tube 14 to dry an optical lens, a heating rod 15 heats water between the partition plate 12 and a heat exchange plate 13, when the air flows through the heat exchange tube 14, the water conducts heat to the air through the heat exchange tube 14, so that the temperature of the air is increased, and meanwhile, the temperature of the air heated to the optical lens can be controlled because the boiling point of the water is 100 ℃; meanwhile, the heat exchange plate 13 preheats the air input by the fan 11, and the air is reheated through the heat exchange tube 14, so that the heat utilization rate is improved.

After the water between the partition plate 12 and the heat exchange plate 13 is heated to cause evaporation, the water vapor is discharged from the liquid filling port 17, and the liquid filling port 17 is used for replenishing the heat transfer liquid between the partition plate 12 and the heat exchange plate 13.

As shown in fig. 1, in order to improve the heat utilization rate, since the hot air is lighter than the cold air, the water is heated and gasified and then flows to the heat exchange plate 13, and the heat exchange plate 13 is a corrugated plate which is continuously bent; by increasing the area of the heat exchange plate 13, the contact area between the gas above the heat exchange plate 13 and the heat exchange plate 13 is increased, and the heat exchange efficiency of the heat exchange plate 13 is improved.
