  Heat exchange systemUSPTO Application #: 20080101779Title: Heat exchange system Abstract: A heat exchange system providing a heat medium in a loop circuit circulating heat exchanger to transfer heat, which mainly uses a water as base material, and the liquid state heat medium is formed by mixing the water with an improving agent or heat carrying particles. The heat medium is filled in a loop circuit heat exchange circulating path having an internal pressure space, and the internal pressure space is used to raise the boiling point and reduce freezing point phase transition temperatures of the water to comply with implementation needs. Hence, the present invention is able to achieve satisfactory strength of heat transfer and unequivocally resolve environmental issues.

BACKGROUND OF THE INVENTION [0001](a) Field of the Invention [0002]The present invention relates to a heat exchange system, and more particularly to a heat exchange system that uses a water (H.sub.2O) as base material, which functions in coordination with a heat exchange circulating path having internal pressure to satisfy heat transfer strength, and unequivocally resolving environmental issues. [0003](b) Description of the Prior Art [0004]In general, heat exchange devices are industrial constant temperature thermostat devices or circulating vane-type electric heaters for indoor heating, wherein mineral oil is used as the interior heat exchange medium. Although specific heat of mineral is relatively low and easily absorbs heat, however, viscosity of the oil itself is relatively high and thus difficult to flow. Moreover, the oil material is heated by the high temperature of the electric heater, which often forms a carbonizing effect, and a coke layer forms on a surface of the heater that affects heating power, and the oil material easily degrades and loses effective heat carrying effect. In general, the oil material must be replaced every three years, and industrial users must replace the oil material every six months. After replacing with new oil, the waste oil then forms a substantial pollution problem, which is not generally accepted, especially in Japan, where it is resold. [0005]Furthermore, over-temperature working of the electric heater results in accumulation of excess internal pressure that affects structural strength, which causes the piping joints to crack, and easily leads to the mineral oil igniting due to electric short circuiting form oil leakage, thereby resulting in fire causing injury to persons and damage to property. [0006]The aforementioned pollution amount produced from the waste oil can be determined if volume of heat conducting oil required by each electric heater is approximately 5 liters, from current global annual production of more than thirty million electric heaters, after multiplication, we arrive at production of more than a hundred million liters of waste oil, which is a pollution hazard that cannot be overlooked. Moreover, low economic value and difficulty in establishing machine-processing recovery of the waste oil creates an obvious source of environmental contamination. SUMMARY OF THE INVENTION [0007]A primary objective of the present invention is to provide a heat exchange system that uses a water (H.sub.2O) as a base material, which is mixed with an improving agent to serve as a heat medium. Physical properties of the heat medium improves heat carrying conditions and phase transition temperatures, and is implemented within a loop circuit type heat exchange path having an internal pressure to broaden the scope of the water phase transition temperatures, thereby meeting the functional requirements for heat exchange, and achieving satisfactory strength of heat transfer. [0008]Another objective of the present invention is to fill the water with high heat conducting heat carrying particles, thereby achieving effectiveness of rapid heat delivery. [0009]A second objective of the present invention is to enable a path space of the loop circuit heat exchange system to accept pressure, thereby producing a relatively high internal pressure, and increasing water boiling point temperature. [0010]A third objective of the present invention is to fill the path space of the loop circuit heat exchange system with the heat medium, wherein volumetric percentage of the heat medium is approximately between 70 and 85%, thereby retaining a space to assimilate expansion. [0011]A fourth objective of the present invention is to add an antifreeze to the water to resist low temperatures by reducing coagulation temperature of the water. [0012]Accordingly, embodiments of the present invention have the following advantages: [0013]1. Provided with non-polluting and noninflammable safety characteristics. [0014]2. No environmental recovery problems when discarded. [0015]3. No environmental pollution problems if there is system leakage. [0016]4. Because noninflammable, household objects, such as carpets, and so on, will not be contaminated or form a combustion supporting action after leakage.
