EXOTHERMAL HEATER Russian patent published in 2010 - IPC F24J1/00 

FIELD: power engineering.

SUBSTANCE: exothermal heater comprises flat thermal module installed in cavity of outer jacket. Body of thermal module is made of two sheets of gas and water impermeable material, which are connected to each other along closed circuit by means of tight seam with provision of closed cavity, where a homogeneous mixture of calcium oxide and waterless silica gel is located, as well as closed chamber of elastic material with water. Closed circuit of tight seam includes two oppositely installed side sections, upper and lower ends of which are pairwise coupled to each other by means of upper and lower sections accordingly, and one of side sections of tight seam is arranged with groove located on inner side of its middle part, which produces zone with lowered mechanical strength in tight seam in the form of link, width of which is less than width of tight seam on according side section. Area of tight seam side section adjacent to at least one of end in each link is arranged in direction towards according link that monotonously expands inside above mentioned closed cavity.

EFFECT: improved efficiency of application of thermal energy released in process of exothermal chemical reaction with simultaneous provision of multifunctionality.
