[0048] The surfaces of the feed port 143 and the discharge port 147 are slidably connected with a cover plate 140, and the cover plate 140 can completely cover the feed port 143 and the discharge port 147 to prevent cooling air from flowing out; the surface of the outer frame 141 is provided with a limiting groove 148, and the limiting groove 148 is slidably connected with the cover plate 140; a spring 149 is arranged in the limiting groove 148; the top end of the outer shield 12 is provided with a feed port 124, and the bottom end of the outer shield 12 is provided with a discharge port 121; the feed port 124 and the feed port 143 are on the same horizontal line, and the discharge port 147 and the discharge port 121 are on the same horizontal line;

[0050] The filtering assembly 14 and the pushing assembly 11 can be provided in one or more groups according to the requirements. For example, two groups are provided in the embodiment of the present invention.

[0051] When in use, the cooling air drawn in by the fan 4 enters the filter assembly 14 through the air inlet 123 to complete filtering, then enters the surface cooler body 13 to be cooled, and then is output through the air outlet 122 to cool the glass substrate 8; wherein when entering the filter assembly 14, the drawn air is filtered by the filter plate 142, and as time goes by, when the filter plate 142 is gradually blocked, the pressure on the filter plate 142 becomes greater, and the filter plate 142 compression spring 146 is gradually pushed to move in the limit groove 144, and as the use time of the filter plate 142 increases, the dust on its surface is more blocked, and the pressure on the filter plate 142 is also greater when the air is continuously blown, and when the filter plate 142 continues to move, the cover plate 140 adapted to the feed port 2 143 is first pushed to move, and then Push the cover plate 140 matched with the discharge port 147 to move. After the cover plate 140 matched with the feed port 143 is completely pushed open, the new filter plate 142 in the container 112 falls from the feed port 1 124 under the action of gravity. At this time, the new filter plate 142 and the old filter plate 142 exist at the same time. The two filter plates 142 still bear huge pressure and move toward the discharge port 147. At this time, the old filter plate 142 containing dust can fall from the discharge port 147 and the discharge port 1 121 under the action of gravity. After the old filter plate 142 containing dust falls, the newly entered filter plate 142 and the cover plate 140 are reset under the action of the spring (because the new filter plate 142 has good penetrability and withstands less pressure); then the new filter plate 142 can be used for filtering.

[0052] In the device of the present invention, the air inlet end of the surface cooler 1 can filter the input air to prevent dust contained in the input air from covering the heat exchange tubes of the surface cooler and affecting the heat exchange efficiency; at the same time, when the filter plate 142 of the filter assembly 14 is blocked due to dust accumulation, it will gradually move under the push of the incoming air to complete the replacement of the new filter plate 142. The whole process does not require shutdown, and can achieve automatic replacement when the filter plate 142 is blocked and affects the filtration efficiency, with high efficiency and low replacement cost.
