Abstract

The present invention provides an energy-saving plate and a method for manufacturing the same. The energy-saving plate of the present invention includes: at least one upper plate, at least one lower plate, at least one inner plate, and a plurality of support structures; a top edge of the upper plate and a bottom edge of the lower plate appear as a straight line; the inner plate is provided between the upper plate and the lower plate, and adjacent plates are separated by the plurality of support structures; an exhausting opening is provided at a lateral side of the inner plate, which is a through-groove inter-penetrating upper and lower surfaces of the inner plate; the periphery of the upper plate, the lower plate, and the inner plate are sealed via a sealing material, so as to form vacuum layers between the plate layers; an exhausting pipe is arranged in the exhausting opening, with which the exhausting opening is sealed together via the sealing material, an open-end of the exhausting pipe is located inside the exhausting opening, and a closed-end of the exhausting pipe is located outside the exhausting opening and is located in the space formed between the upper plate and the lower plate. In the present invention, a total flat surface of the energy-saving plate is achieved without structure defects, thus enhancing the strength of the energy-saving plate.

Claims

1. A panel comprising:

a first plate comprising glass;

a second plate comprising glass;

a third plate between the first and second plates, the third plate comprising a flexible material;

a first plurality of support structures sandwiched between the first plate and the third plate;

a second plurality of support structures sandwiched between the second plate and the third plate, wherein

peripheries of the first, second and third plates are aligned and sealed to form a first vacuum chamber between the first and third plates and a second vacuum chamber between the second and third plates,

the third plate comprises a notch at an edge of the third plate and formed between the first plate and the second plate, the notch providing a fluid channel connecting the first and second vacuum chambers such that the first and second vacuum chambers are in fluid communication and under a same vacuum pressure,

the second plurality of support structures are off-set from the first plurality of support structures such that the support structures and the third plate form non-linear thermal pathways from the first plate to the second plate, and

a pumping pipe enclosed within the notch and between the first plate and the second plate, the pumping pipe having an open end in fluid communication with the fluid channel and a terminal closed end,

wherein the first and second plates have straight peripheral edges.

2. The panel of claim 1, wherein the notch is U-shaped.

3. The panel of claim 1, wherein the peripheries of the plates are sealed with a sealing material.

4. The panel of claim 1, wherein each one of the plates has a flatness of larger than 10 nm/m.

5. The panel of claim 1, wherein the third plate comprises a central plate body and a frame around the central body, and a portion of the fluid channel is formed between the central plate body and the frame.

6. The panel of claim 5, wherein the frame is generally C-shaped.

7. The panel of claim 1, wherein at least one of the first and second plates comprises a groove or recess on an inner side of the at least one plate aligned with the fluid channel.

8. The panel of claim 1, further comprising a getter in the fluid channel.

9. The panel of claim 1, wherein the vacuum pressure is 10⁻

6 Pa to 10 Pa.

10. The panel of claim 1, wherein the panel is a glass panel.

11. The panel of claim 1, wherein the third plate is deformable to increase the uniformity of the forces distributed to the support structures through the third plate.

12. The panel of claim 3, wherein the fluid channel is sealed by the sealing material and the pumping pipe sealingly extends through the sealing material.
