  Trihex (tm) heat exchangerUSPTO Application #: 20070079958Title: Trihex (tm) heat exchanger Abstract: A device for the exchange of heat between one or more fluids. This invention has three side walls (10) and two end flanges (12) forming the main body of the invention. An inlet conduit (22) brings a fluid to the inlet port (20) situated on the invention. An outlet port (24) allows the fluid to pass out of the invention and into an outlet conduit (26). Fins (16) increase the surface area and partitions (18), as well as adding surface area, provide a means of directing the flow of fluid through the invention. The invention may be enclosed by exterior walls (14) to form auxiliary heat transfer areas (28).

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of provisional patent application Ser. No. 60/725,755, filed Oct. 11, 2005 by the inventors. FEDERALLY SPONSORED RESEARCH [0002] Not Applicable SEQUENCE LISTING OR PROGRAM [0003] Not Applicable BACKGROUND OF THE INVENTION [0004] 1. Field of Invention [0005] This invention relates to heat exchangers, devices that transfer heat between fluids without the fluids coming into direct contact with each other. [0006] 2. Prior Art [0007] A heat exchanger must have a maximum surface area to transfer the maximum amount of heat from one substance to another. Conventional heat exchangers, such as U.S. Pat. No. 7,111,671 Heat Exchanger Having Air Drying Device to Symonds (2006), have surfaces that are smooth, limiting the amount of surface area from which heat can be transferred. [0008] Flat plate heat exchangers such as U.S. Pat. No. 7,108,054 Heat Exchanger to Dilly, Beldam, and Ayers (2006), have a plurality of plates. This increases the surface area due to the number of plates contained in this invention but the plates still have smooth surfaces. Again, this limits the amount of heat that can be exchanged. [0009] U.S. Pat. No. 6,488,078 Heat Exchanger Tube Structured on Both Sides and a Method For Its Manufacture to Beutler, et al. (2002) attempts to increase surface area by producing grooves on the inside and outside of the heat exchanger tube. This approach does increase surface area but only marginally. [0010] U.S. Pat. No. 7,096,932 Multi-Fluid Heat Exchanger and Method of Making Same to Scoville et al. (2006) uses a number of slots, headers and baffles to increase the surface area of said heat exchanger. Whereas this method does indeed increase the surface area, it is also complex and tedious to build. [0011] An attempt to increase surface area by forcing a fluid through an enclosed tube that has been bent into several curves received U.S. Pat. No. 7,096,933 Furnace Heat Exchanger to Zia et al. (2006). This increased the surface are heat exchanger to a minimum. This embodiment increases surface area and serves to keep the heat exchanger in a relatively compact design. It still suffers from limited surface for transfer of heat since its surface is smooth. OBJECTS AND ADVANTAGES [0012] Several objects and advantages of this invention are: [0013] (a) to provide a heat exchanger that has the flexibility to be of any size desired; [0014] (b) to provide a heat exchanger that has a significantly increased surface area for greatly improved heat transfer capability between fluids; [0015] (c) to provide a versatile heat exchanger to fulfill a vast array of applications and configurations; [0016] (d) to provide a heat exchanger that can be used for extremely high fluid temperatures and fluid pressures, and a multitude of fluids; [0017] (e) to provide a heat exchanger that can be used as a stand alone heat exchanger or used in a plethora of combinations such as, but not limited to: [0018] (1) connected end to end; [0019] (2) connected side by side; [0020] (3) connected one on top of the other; or [0021] (4) connected from the outlet of one heat exchanger to the inlet of another heat exchanger; [0022] (f) to provide a heat exchanger that can also serve as a fluid mixer; [0023] (g) to provide a heat exchanger that can be used to transfer heat from one fluid to another or plurality of other fluids; [0024] (h) to provide a heat exchanger that can be used to transfer heat from a plurality of fluids to another single fluid; [0025] (i) to provide a heat exchanger that can be used to transfer heat from a plurality of fluids to a plurality of fluids; and [0026] (j)to provide a heat exchanger that can be easily built. SUMMARY [0027] In accordance with the present invention a heat transfer device having three side walls 10, two end flanges 12, an inlet port 20 and outlet port 26 or a plurality thereof and an inlet conduit 22 and outlet conduit 24 or a plurality thereof. The invention may also consist of one fin 16 or a plurality thereof, one partition 18 or a plurality thereof, and/or one or a plurality of exterior walls 14 attached to the exterior of invention. The figures listed below may or may not be included in each embodiment of the heat transfer device. DRAWINGS--FIGURES [0028] In the drawings, figures may be defined by a number or a number with an alphabetical suffix or several alphabetical suffixes to help clarify the construction of said invention. [0029] FIGS. 10, 10A and 10B show a Side Wall with each edge delineated for easy reference during explanation of construction of the invention. The Side Walls form the main body of the invention. [0030] FIG. 12 and 12A, and show an End Flange with each edge delineated for easy reference during explanation of construction of the invention. The End Flanges are used to enclose the Side Walls. [0031] FIGS. 14A, 14B, 14C, 14D and 14E show an Exterior Wall with each edge delineated for easy reference during explanation of construction of invention. The Exterior Walls may be used to contain fluid outside the main body if desired but not mandatory for this invention. Continue reading...
