Title:
HEATING BODY, AND VACUUM FURNACE WITH MULTI-REGION TEMPERATURE CONTROL
Document Type and Number:
WIPO Patent Application WO/2021/227126
Kind Code:
A1
Abstract:
Disclosed are a heating body and a vacuum furnace with multi-region temperature control. In the heating body, first ends of a plurality of first heating sheets in a first heating unit are connected to a first connecting sheet in parallel, and second ends thereof are connected to a first corner connecting sheet in parallel; first ends of a plurality of second heating sheets in a second heating unit are connected to the first corner connecting sheet in parallel, and second ends thereof are connected to a second corner connecting sheet in parallel; and first ends of a plurality of third heating sheets in a third heating unit are connected to the second corner connecting sheet in parallel, and second ends thereof are connected to a second connecting sheet in parallel. A first electrode bar is fixed to the first connecting sheet, and the first electrode bar is configured to be connected to a first terminal of a single-phase transformer; and a second electrode bar is fixed to the second connecting sheet, and the second electrode bar is configured to be connected to a second terminal of the single-phase transformer. A radial cross section of the heating body is U-shaped, and the first connecting sheet and the second connecting sheet are not coplanar. The present invention can reduce the difficulty of regulating the temperature of a vacuum furnace and improve the temperature uniformity of the vacuum furnace.
