High-Performance Heater

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention is a compact, high-power heater capable of raising the temperature of solid materials or samples above 1800 K (up to 2500 K surface temperature). It achieves this through a stacked arrangement of two or more heating layers containing wound heating wires (coils). Each layer's wire pattern is offset with respect to its neighbor, maximizing heat output and uniformity. The heater is designed for high performance and can operate in vacuum environments, making it suitable for applications requiring intense localized heating.

Use CasesContent extracted from patent full text and abstract with AI.

• Testing material samples under high temperature conditions, including fusion reactor wall materials.
• Heating solid samples for research or analysis in vacuum chambers.
• Simulating extreme thermal stress for turbine coatings or other advanced materials.
• Providing a controlled, high-temperature environment for studies of plasma-material interactions.
• Use in laboratory or industrial processes where compact, high-performance heating is needed and space is limited.

BenefitsContent extracted from patent full text and abstract with AI.

• Delivers extremely high surface power density (up to 1 MW/m²), enabling very high temperature generation in a compact device.
• Suitable for vacuum operation, which traditional heaters often cannot achieve due to oxidation or other thermal limitations.
• Provides uniform heating, minimizing local overheating and ensuring sample integrity during testing or analysis.
• Highly compact and can be integrated into setups with limited available space.
• Flexible design allows adaptation to different sample geometries or specific research needs.

Patent Abstract

The invention relates to a compact high-power heater for heating material objects to temperatures above 1800 K. The heater has at least two or more heating layers which are arranged adjacent to one another and have at least one wound heating wire in a specific arrangement. The arrangement of the wound heating wire in a first heating layer is offset in relation to the arrangement in said adjacent heating layer in such a way that the intermediate spaces in the wound heating wire in the first heating layer are predominantly covered by said arrangement in an adjacent heating layer. The form of a worm running in opposite directions is advantageously provided as the arrangement for the wound heating wires. The heater according to the invention has an area output of more than 500 kW/m2, and in particular up to 1 MW/m2, owing to its highly compact construction, and is therefore advantageously suitable for carrying out investigations on material samples which are subjected to high temperatures, in particular even under vacuum.
