Portable heating systems and methods

Abstract

The present invention relates to portable heating systems for generating heat through various exothermic reactions excluding combustion of inflammable gases and liquids and carbon-containing fossil fuels. More particularly, the present invention relates to portable air heating systems generating heat by the exothermic chemical reactions and delivering heat to a target by conduction or convection. The present invention also relates to various portable heating systems supplying reactants, air, and / or heated air into and / out of such by a driving force generated by ordinary bodily movement of an user. Thus, the present invention relates to gloves, shoes, and cloths incorporated with the portable heating systems to keeping the user warm in cold weather. The present invention also relates to methods of generating heat by the portable heating systems and methods of applying such systems to the gloves, shoes, and cloths. The present invention also relates to processes for making such portable heating systems and processes of fabricating gloves, shoes, and cloths incorporated with such systems.

AI Technical Summary

Benefits of technology

"The present invention relates to a portable heating system that can generate heat through exothermic chemical reactions without burning inflammable gases or liquids, or producing toxic or harmful substances. The system can be designed to deliver heat to a user through direct thermal conduction or forced convection. The reactants used in the system can be in various shapes and arrangements to maximize heat generation and can be easily replaced when consumed. The system can also incorporate into various articles such as gloves, shoes, and cloths. The invention aims to provide a safe, slow, and controllable mode of heat generation for portable use."

Problems solved by technology

Thus, modifications of such devices into portable articles have not yet been successful.

Although the portable electric heaters may be useful in some occasions, their applications are limited in that the batteries tend to be heavy and bulky, such batteries may last only several hours, and the like.

It is cumbersome to carry tens of extra batteries to replace the used ones and to recharge the rechargeable batteries whenever such heaters are to be used in the future.

Although the energy source of the portable burners such as the fuel tanks and canisters of inflammable gas are generally less cumbersome to carry, flame temperature of such heaters may be relatively high, and no suitable methods have been developed to control the flame temperature at a range not detrimental to a skin of an user.

Although this heating device may generate heat at a low temperature, it is typically difficult to control heat generation once the powder begins to burn.

In addition, this device does not have enough heating capacity to last more than a few hours.
