Abstract

A heat exchanger comprises a casing 20 having an inlet 21 and an outlet disposed at opposite ends, a helical member 30 for producing a spiral flow path 31 of a fluid and extends around an energy source 10 which is sealed against the casing by a seal member 40. The helical member 30 may be a spiral spring member. The energy source 10 may be electrical energy and may be made to discharge a high voltage for generating ozone, anions or electrolyte, or made of permeable material and adapted to transmit infrared or ultraviolet light to sterilize the fluid. The casing 20 and helical member 30 may have fins (22, 32, fig 4) which generate turbulent flow disposed on the inside of the casing 20 and on the periphery of the helical member 30 respectively. The helical member 30 may be integrally formed with the casing 20 and have fins (32, fig 5) disposed in the spiral flow path 31, and may be formed as two separate members (fig 6).

Description

ENERGY EXCHANGING APPARATUS
The present invention relates to an energy exchanging 5 apparatus and, more particularly, to a high performance energy exchanging apparatus.
FIG. 1 shows an energy exchanging apparatus according to the prior art. According to this design, the energy exchanging
10 apparatus comprises a cylindrical energy source 10a adapted for providing/delivering cold/hot energy, a conduit 20a provided around the cylindrical energy source 10a and adapted for delivering a fluid to make energy exchange with the cylindrical energysource 10a,and a inlet 21a disposed on one end of the conduit 20a, the 15 inlet 21a is used for transporting fluids. This design of energy exchanging apparatus is not satisfactory in function. Because the conduit 20a has a circular crosssection, the contact between the periphery of the cylindrical energy source lea and the periphery of the conduit 20a is a line contact, the fluid passing through the 20 conduit 20a absorbs less energy from the cylindrical energy source lea. Further, because the conduit 20a has a circular cross-section, the flow passes through the conduit 20a rapidly and straightly forwards without causing turbulence. Therefore, the heat exchange
performance is less efficient.
The present invention has been accomplished to provide an energy exchanging apparatus, which eliminates the aforesaid 5 drawbacks. It is therefore the main object of the present invention to provide an energy exchanging apparatus which preferably causes a turbulent flow when a fluid passing through the conduit around the energy source, enhancing the action of energy exchange. To achieve these and other objects of the present invention, the energy 10 exchanging apparatus comprises an energy source adapted for providing/delivering energy (heat energy, electric energy, energy of infrared or ultraviolet light, etc.), a shell provided around the energy source and adapted for delivering a fluid to make an energy exchanging action with the energy source, and a spiral member 15 provided inside the shell and spirally extended around the periphery of the energy source and defirung a helical flow path for guiding the fluid helically over the periphery of the energy source.
Preferred embodiments of the invention are described below by way of example only win reference to FIGS. 1 to 6 of the accompanying drawings, 20 wherein FIG. 1 is a side view in section of an energy exchanging apparatus according to the prior art.
FIG. 2 is an exploded view of an energy exchanging apparatus according to the first embodiment of the present invention.
( FIG. 3 is a side view in section of the energy exchanging apparatus according to the first embodiment of the present invention. FIG. 4 is a side view in section of an energy exchanging 5 apparatus according to the second embodiment of the present invention. FIG. 5 is a side plain view of an energy exchanging apparatus according to the third embodiment of the present invention. 10 FIG. 6 is a side plain view of an energy exchanging apparatus according to the fourth embodiment of the present invention. Referring to FIGS. 2 and 3, an energy exchanging apparatus 15 according to the first embodiment of the present invention is shown comprised of a energy source 1O, a shell 20, a spiral member 30, and a seal member 40. According to the present invention, the energy source 10 provides/delivers heat or electric energy, or energy of light. The shell 20 according to this embodiment is a 20 conduit holding the energy source 10 on the inside and, adapted for delivering a fluid over the periphery of the energy source 10. The seal member 40 is fastened to the periphery of the energy source 10 and one end of the conduit 20 to seal the gap. The conduit 20 has an
inlet 21 extended from one end thereof for the input of a fluid, and an outlet (not shown) extended from the other end thereof. The spiral member 30 is a spiral spring member mounted within the conduit 20 and spirally extended around the periphery of the 5 energy source JO, defining a spiral flow path 31 around the periphery of the energy source 10.
When a fluid delivered through the conduit 20, the fluid absorbs energy from the energy source JO, making an energy exchanging action. When the fluid delivered into the conduit 2O, it ID flows spirally along the spiral flow path 31, increasing energy exchanging time.
The aforesaid energy exchanging apparatus is practical for use in a heat exchanger, electric water heater, electric steam generator, and etc. The energy source 10 can be made of light 15 permeable material, and adapted to emit infrared light or ultraviolet light. When a fluid passing through the conduit 20, the radiation of infrared or ultraviolet light sterilize the fluid. Alternatively, the l energy source 10 can be made to discharge high voltage for generating ozone, anions or electrolyte.
20 FIG. 4 shows an energy exchanging apparatus according to the second embodiment of the present invention. This embodiment is similar to the aforesaid first embodiment of the present invention with the exception of the arrangement of fins 22 around the inside
wall of the conduit 2Q and fins 32 around the periphery of the spiral member 30. The fins 32 of the spiral member 30 are suspended in the spiral flow path 31. The fins 32 disturb the fluid passing through the spiral flow path 31, causing a turbulent flow.
5 FIG. 5 shows an energy exchanging apparatus according to the third embodiment of the present invention. According to this embodiment, a spiral member 30 is formed integral with the inside wall of the conduit 20, having fins 32 suspended in the spiral flow path 31.
10 FIG.6 shows an energy exchanging apparatus according to the fourth embodiment of the present invention. This embodiment is similar to the aforesaid third embodiment of the present invention with the exception that the spiral member 30 is formed of at least two sub-spiral member.
15 A prototype of energy exchanging apparatus has been constructed with the features of the annexed drawings of FIGS 26 The energy exchanging apparatus functions smoothly to provide all of the features discussed earlier.
Although particular embodiments of the invention have 20 been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
