Innovative heating module

Ref-Nr: TDO0160

Technology abstract

Based on innovative materials structure and smart use of opposing magnetic fields, this technology has been developed as part of a thesis in order to provide heating energy to satellite components located in shadow zones. It consists of a module composed of many layers of specific materials (complex mineral materials and some metals).

Technology Description

The method uses low electric current (0.5A to 2A) and delivers powerful opposing magnetic fields inside a module using the ?Coronal Architecture?. The Coronal Architecture is an innovative materials architecture that optimizes and controls the electromagnetic induction and avoids the use of a winding.

The technology is composed of many layers of specific materials (complex mineral materials and some metals) and the high-power electromagnetic field produced by the coronal architecture creates electromagnetic disturbances in the materials inside the module. The thermal motion is then directed through these dipoles in random directions.

The electronic movements of the electrons in the material (called SNM and composed in part of (Mg,Fe)2 (SiO), (Mg,Fe)7 (SiO3)2) are disturbed, which modifies the magnetic moment of the electron.

The high heating crosses the magnetic fields in the different layers of the module and creates intense thermal motions inside the module. Comparable to a micro power plant, it begins to warm in the middle of the module and the heat moves progressively through the different layers to warm the whole material.

These ecological SNM Materials have been chosen for this application because of their exceptional inertia, and magnetic/thermal performance.

Tests have shown that this abundant natural material doesn?t oxidize, doesn?t explode and stays stable at more than 1000�C.

Further Information

ome experiments have been conducted to measure the performance of each material selected, specifically: melting point, resistance, thermal inertia. One aim of the experiments was to increase the speed of heating and to reduce the speed of cooling, with minimal use of power. However, the materials have their own mechanical and physical limits, and it was thus necessary to find an innovative induction technology. The Coronal Architecture was created to answer these challenges.
The curves show that, with 3V (volt), three products: Copper, Neodymium/iron/Boron, and ferrite struggle to exceed a temperature of 80�C. The two strategic natural materials, ?Sab. Blanc? and ?Sab. Noir? are more sensitive to the inductive electromagnetic field. With the same current (3V and 1 A), the sab. noir reaches 140�C.
After some physical transformations of the natural materials, the performance has been improved, for example to reduce the delay in warming.
Electromagnetic fields produced with (3Volts) by the ?Coronal Architecture? are concentrated in the center of the triangle. Compared to three laser rays concentrated in one point, the heat caused by the coronal architecture moves to the center of the module, which become warmer than the rest. With this module we experimented with the possibilities to modulate the temperature in some parts of the module, depending on the need.
 

Current and Potential Domains of Application

Relevant non-space applications could be hand and clothes warmers after the miniaturization of the module and components.

Medical applications:

  • Glove and slipper warmers for peoples suffering from some diseases such as ?Raynaud?s phenomenon? which causes excessively reduced blood flow in response to cold or emotional stress, causing discoloration of the fingers, toes, and occasionally other areas.

Industrial applications:

  • Warm vest for fishermen
  • Seat Heaters in the automotive industry
  • In Microelectronics to make one device to welded, etc.
  • Warm clothes for operators on oil rigs, for servicemen
  • Sports and hobbies: ski suits, sleeping bags.
