Abstract

The present disclosure provides a condensing plate. The condensing plate comprises a body. The body comprises a first face and a second face opposite to the first face. The first face is provided with a condensing part and a solvent storage structure. The solvent storage structure is configured to store a solvent and release, along a direction away from the second face, gas formed by the solvent after evaporation.

First claim

I claim:

1. A condensing plate, comprising:
a body comprising a first face, a second face opposite to the first face, and a cooling channel configured to accommodate a coolant,
wherein the first face comprises a condensing part and a solvent storage structure,
wherein the solvent storage structure is configured to
store a solvent, evaporate the solvent, and release gas formed by the solvent after evaporation, wherein the gas is released along a direction from the second face to the first face.

2. The condensing plate of claim 1 ,
wherein the first face comprises a middle region and an edge region surrounding the middle region, and
wherein the solvent storage structure is in the edge region.

3. The condensing plate of claim 2 , wherein an orthographic projection of the solvent storage structure on a plane of the first face or the second face comprises an annular projection.

4. The condensing plate of claim 3 , wherein an outer ring and an inner ring of the annular projection are rectangles.

5. The condensing plate of claim 3 , wherein a ring width of the annular projection is in a range of 1 mm to 100 mm.

6. The condensing plate of claim 1 , wherein the solvent storage structure comprises a film layer comprising a plurality of adsorption pores.

7. The condensing plate of claim 6 , wherein a material of the film layer comprises one of silicone, polypropylene or fluorine-containing material.

8. A vacuum drying device, comprising:
a chamber configured to provide a vacuum environment,
a base platform, and
the condensing plate according to claim 1 ,
wherein the condensing plate is opposite the base platform in the chamber, and
wherein the base platform is configured to carry a substrate to be dried.

9. The vacuum drying device of claim 8 , wherein the base platform is further configured to heat the substrate for drying.

10. The vacuum drying device of claim 8 , wherein the first face faces the substrate for drying.

11. The vacuum drying device of claim 8 , wherein an orthographic projection of the solvent storage structure on a plane of the substrate comprises an annular projection.

12. The vacuum drying device of claim 11 ,
wherein an outer ring of the annular projection comprises a rectangle,
wherein a length of the outer ring is greater than a length of a region for drying of the substrate, and
wherein a width of the outer ring is greater than a width of the region for drying.

13. The vacuum drying device of claim 11 ,
wherein an inner ring of the annular projection comprises a rectangle,
wherein a length of the inner ring is less than a length of a region for drying of the substrate, and
wherein a width of the inner ring is less than a width of the region for drying.

14. The vacuum drying device of claim 8 , further comprising:
a solvent supply device,
wherein the solvent supply device is configured to supply the solvent to the solvent storage structure.

15. The vacuum drying device of claim 14 , further comprising:
a detection device configured to detect a solvent amount in a unit area of the condensing part; and
a control device configured to adjust a solvent supply amount of the solvent supply device based on a detection result.

16. The vacuum drying device of claim 15 , wherein the solvent supply device comprises:
a storage container configured to store the solvent;
a supply pipeline interconnecting with the storage container and configured to supply the solvent in the storage container to the solvent storage structure; and
an adjusting valve on the supply pipeline and configured to adjust a supply flow of the supply pipeline under control of the control device.
