Title:
HOT PLATE AND DESICCATOR
Document Type and Number:
WIPO Patent Application WO/2010/024122
Kind Code:
A1
Abstract:
Disclosed are a hot plate that maintains a uniform temperature on a flat surface, and a desiccator and vacuum desiccator that use this hot plate.
Multiple heating elements (13) and the same number of temperature sensors (14) as heating elements (13), which are adjacent to the heating elements (13), are provided in a plate (11), which is made from a metal with relatively good thermal conduction, and a temperature control circuit, which compares the plate temperature data from the temperature sensors (14) with a desired set temperature and controls the amount of heat generated by the heating elements (13), is disposed on each heating element (13), making it possible to set the surface temperature of the hot plate to a desired temperature distribution. Power transistors are used as the heating elements (13) and are arrayed in a grid.
