Abstract
Abstract A closed heating system in which a silicone fluid having a high specific heat is pumped through an element formed of tetrafluoroethylene. The element is provided with a plurality of small openings through which the fluid is forced. The fluid is heated and the heated fluid is forced to blow through one or more heat transfer units through which heat is transferred to the ambient atmosphere.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
203 words
A closed heating system comprising: a liquid storage tank; a liquid in the liquid storage tank; a pump connected to the liquid storage tank to pump liquid therefrom; means for operating the pump; at least one heat transfer means; a heat generating unit; a first liquid distribution line connected from the pump to the heat generating unit; a second liquid distribution line connected from the heat generating unit to the heat transfer means; a third liquid distribution line connected from the heat transfer means to the pump to thereby form a closed system; the liquid being somewhat compressible and having a specific heat in the order of 0.86; the heat generating unit being formed of a synthetic resin material having a melting point above 300° F and having a plurality of small holes therein through which the liquid is forced, the holes being of such size that a back compressional force is developed in the liquid not flowing through the openings thereby causing the temperature of the liquid to rise and deliver heat to the heat transfer means; the thermal integrity of the heat generating unit being such that the back compressional force is maintained over the operating temperature range of the liquid.

Claim 10
Dependent Claim
145 words
In a closed heating system utilizing a liquid having a high specific heat as the heat transfer medium and having storage means for storing the liquid, pump means for pumping the liquid through the system, a heat generating unit to which the liquid is pumped to thereby heat the liquid, heat transfer means for transferring heat from the liquid to the ambient atmosphere, the heat generating unit comprising: a block of synthetic resin material having a melting point above 300° F; the block having a plurality of small longitudinal openings through which a small quantity of the liquid is forced to thereby develop a back compressional force in the liquid not flowing through the openings which causes the liquid temperature to rise; the thermal integrity of the block being such that the back compressional force is maintained over the operating temperature range of the liquid.
