Description

This invention relates generally to an auxiliary heating system, and more particularly to an improved auxiliary heating system for heating coolant, and having easily removable and replaceable heating elements that can be installed or removed easily from the auxiliary heating system. The auxiliary heating system is also preferably arranged as a continuous, interconnected flow circuit, therefore warming the coolant in a faster and more efficient manner.

DESCRIPTION OF THE PRIOR ART

It is well known that certain types of heating systems have utilized electrical elements internally positioned within a pre-heater, whereby coolant can be heated by the electrical element so as to heat an area. U.S. Pat. No. 5,408,960 (Woytowich) and U.S. Pat. No. 4,770,134 (Foreman et al) are examples of such devices. However, these arrangements feature electrical heating elements that are internally positioned and firmly set within a tank or chamber, and do not allow for easy removal of the electrical element from the pre-heater without complete disassembly, or destruction, of the pre-heater, should maintenance or replacement of the electrical element be required. In such maintenance or replacement situations, the entire pre-heater would be required to be removed from the heating system to access the internal electrical heating element, thereby making maintenance and replacement of such components difficult and complicated.

What is required is an auxiliary heating system which is very economical, possesses a minimal footprint, and which can generate substantial amounts of heat to heat larger spaces, such as in a home or business, and which can be utilized in various implementations and configurations, such as in a home, vehicle, radiant floor heating or various other uses. Thus, there is a need for an improved environmentally friendly heating system for heating a space which has a generally uncomplicated and simple design, which may be installed easily, and is durable and reliable, and which possesses easily removable or replaceable heating elements. In this regard, the present invention substantially fulfills this need.

FIG. 1 is a perspective view of one embodiment of the auxiliary heating system of the present invention;

FIG. 2 is an exploded view of an embodiment of the heating elements arranged to be positioned to reside within the formed chambers of the piping of the auxiliary heating system of the present invention; and

FIG. 3 is an exploded view of an embodiment of at least some of the various components of the auxiliary heating system of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

In the preferred embodiment, and with reference to FIG. 1, the heating system comprises various components, as hereinafter described, and which can include a power source 1, all of which may optionally be contained in a portable case 9 for ease of transport. Further, by virtue of the system having such a minimal footprint, the system can be interconnected for use with existing systems and hardware already present in, for example, a home, vehicle, radiant floor heating or various other uses, which would be readily understood by one skilled in the art. Such existing piping 11, as an example, can be seen in FIG. 1, and could be interconnected with first flow pipe 7 and a second flow pipe 8 shown in FIGS. 1 and 2.

The system comprises a first flow pipe 7 and a second flow pipe 8 which are interconnected to form a closed fluid flow circuit, through which coolant may flow. The closed fluid flow circuit will preferably be in a vacuum environment. A pump 3 is also utilized in the system to continuously circulate the coolant through the fluid flow circuit.

As can also be readily seen in FIG. 2, heating elements 5 are inserted through at least one integrally formed chamber opening 15 positioned along the length of interconnected piping, it being understood, of course, that such positioning can occur anywhere along a length of the interconnected piping, so that a lower end of the heating element 5 projects from the formed chamber opening 15 into the closed fluid flow circuit to be in direct contact with the coolant.

As can be seen in FIGS. 2 and 3, the interconnected piping extends substantially horizontally, and comprises at least one formed chamber opening 15, but more preferably, a plurality of formed chamber openings 15 defined thereon, each of which are separate from the separate from the first flow pipe 7 and the second flow pipe 8.

Preferably, the heating elements are DC electrical heating elements, though it is conceivable that other heating elements, such as glow plugs, could be utilized. These can be easily removable and replaceable if required. In a preferred embodiment, each of the formed chamber openings 15 will have an associated heating element 5 inserted therein. FIG. 1 illustrates 3 such removable heating elements 5 being utilized, though it will, of course, be understood that numerous variations to this number are possible.

The heating elements 5 are supplied with power from a power source 1 for enabling the heating elements 5 to heat the coolant within the fluid flow circuit. For example, some heating elements can be heated to 3500 degrees, or temperatures in varying other degrees, and this amounts to a considerable temperature which can be generated to heat the coolant flowing in the fluid flow circuit. In one embodiment, the power source 1 is an electrical type power source, or a power pack that can be plugged in by means of a power cord outlet 13, shown in FIG. 1, though it is conceivable that, alternatively, other types of power sources could be utilized, such as solar power cells, NC power, DC power pack, wind generated power sources or the like, as would be apparent to one skilled in the art. Of course, it would be readily apparent that such a power cell could also be re-energized or re-charged also, as is also known in the art. The power from the power source 1 is connected to the heating elements 5, along with the pump 3 and the flow switch 17 (as hereinafter described) by conventional means such as wiring.

With reference to FIG. 3, the heating system further includes a flow switch 17 for monitoring flow of the coolant through the closed fluid flow circuit, wherein, if the flow has ceased through the closed fluid flow circuit, the flow switch 17 instructs the system to deactivate the heating elements to prevent damage to the heating elements 5.

In a further optional embodiment, the flow switch 17 may instruct, as an example, a thermostatic safety control (not shown) in association with the heating elements 5 and the other components therein, in a conventional known manner, and which would be adapted to turn the heating elements 5 off when a temperature of the coolant within the fluid flow exceeds a pre-determined level, or when it is detected that a component has failed. For example, if the pump malfunctions and is no longer circulating the coolant, or if there is insufficient coolant in the system, the thermostatic safety controls activates to shut down each of the heating elements 5. Additionally, the thermostatic control can be adapted to turn the heating elements on when a temperature of the coolant falls below a pre-determined level.

In an exemplary embodiment, radiator panels (not shown) can be connected to the fluid flow circuit, to radiate the heat from the heated coolant flowing in the fluid flow circuit to a space (not shown) to be heated by the heating system. Such a space could be, for example, a home, a room, radiant floor heating, an office or building, or the like.

It is conceivable that the present invention could be utilized, but not limited to, such applications as heating a greenhouse, use in vehicles, radiant flooring, heating an office or the like, or a home or building. In addition, it is also conceivable that a water source could also be interconnected with the closed fluid flow circuit of the present invention. Such a water source could be, as an example only, a water heater, which could be deactivated from operation, but which would provide sufficient quantities of water for the system. Other variations to this are possible also, as would be apparent to one skilled in the art. In another embodiment of the present invention, the heating system of the present invention can be a stand alone heating unit.

The heating system of the present invention could also be selectively activated (or deactivated) by a remote device (not shown) by a user, whereby the power source 1, activates the heating elements 5 from a distance. Of course, the system can also contain thereon a conventional on/off switch (not shown), as would be apparent to one skilled in the art.

The present invention has been described herein with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein. Such variations can include, but is not limited to, Homes and cottages—in-floor and in-wall heating assembly systems, and in terms protecting water supply from freezing; Radiated heating assembly mounted to aluminum or cast iron radiators;

Radiated heating assembly in-floor heating and cement slabs; Heating homes on separate zones between floor and wall; Forced air systems, featuring uilt auxiliary heating assemblies in natural gas, oil or propane furnaces operating on solar, wind, lithium batteries and a generator; Heating assemblies in a free standing portable system which are easily transferrable from one application to another, and having snap on connections in various sizes; Railway switches, oil well heads, natural gas heads, mining applications, operations, and those using solar energy, wind energy, lithium batteries and a generator as power sources; Use in land vehicles such as heavy trucking, earth movers, transport trucks, buses, and light vehicles, for transferring the heat through the entire engine, inside the cab and to keep batteries completely charged; Marine Vessels—where the heating system generates heat through the entire vessel preventing mildew, mold and weakening of the inner structure; Industrial applications where the heating system is scalable to heat an industrial building, using solar, wind, lithium batteries and a generator, with zero emissions to exhaust; Applications such as heating hot tubs, swimming pools, tents, mobile homes, and trailers; Aviation applications, where the heating system is also designed to create heat on small engines; and use in operations at extremely cold temperatures of −40 and under.
