Heat exchanger

Abstract

A heat exchanger comprising a chamber other than a coil is provided. The heat exchanger withstands high operating pressures and allows a reduction of fuel, avoiding the excessive generation of pollutants.

Claims

1. A heat exchanger that withstands 3000 psi of hot water pressure at 180 F. (82.2 C.), the heat exchanger comprising: an outer tube having a water inlet for receiving cold water therein and a hot water outlet for producing hot water therefrom; an intermediate tube inserted into the outer tube to form a chamber therebetween; an inner tube inserted into the intermediate tube and having a heat inlet therein; a transition section having a tubular cylindrical portion positioned at one end of the outer tube, the intermediate tube, and the inner tube and a domed portion positioned on the tubular cylindrical portion with the tubular cylindrical portion and the domed portion having an interior in fluid communication with the chamber; an insulator covering the transition section domed portion, at least partially; an interior sheet positioned around the outer tube for sealing gases therein; an exterior sheet positioned around the interior sheet that includes insulating material therein; wherein a plurality of dividers is positioned between the outer tube and the intermediate tube, so that the chamber is divided into at least two divisions with each division being in fluid communication with the transition section interior, so that cold water flows into the water inlet, circulates from one of the divisions to the second division through the transition section interior, receives heat from the inner tube to transform the cold water into hot water, flows from the second division and out of the hot water outlet.

DETAILED DESCRIPTION OF THE INVENTION

(8) The present disclosure provides a heat exchanger which differs from those described in the prior art by its design. Particularly, the heat exchanger of the present disclosure comprises a chamber other than a coil, which withstands 3000 psi of hot water pressure to 180 F. (82.2 C.). The present heat exchanger invention withstands steam at temperatures of 392 F. (200 C.).

(9) Referring now to the drawings and, in particular, to FIG. 1, the heat exchanger includes a heat inlet 1, a cold-water inlet 2, a hot water outlet 3, and an insulator A. The heat exchanger is defined by a tube inside another tube wherein there is a chamber containing water.

(10) Water is passed in a certain direction to receive the increased heat exchange that is generated by a burner that uses diesel fuel. The combustion gases are also directed in one direction so that they have the longest contact surface with the exchanger, thus achieving a double passage of the combustion gases, which increases its efficiency and reduces diesel consumption by approximately 40%.

(11) The heat exchanger is also comprised of an internal sheet (IS) that functions as a seal to benefit the appropriate circulation of gases. Furthermore, this exchanger is also comprised of an exterior sheet (ES) that provides a proper seal, and also functions as insulation against burns.

(12) FIG. 2 has an insulator illustrated with the reference (IS); this insulator can be of mineral wood. Moreover, the function of the exterior sheet (ES) is to avoid people burning themselves when they come into contact with this part.

(13) FIG. 3 discloses an exterior sheet 3 that is used within the heat exchanger.

(14) FIG. 4 shows a heat inlet 1, and the internal circulation of gases through the heat exchanger structure. This is a double circulation, which means that it emits double the heat.

(15) FIG. 4 shows how the heat enters through the internal part and exits through the external part. That is, heat enters through the heat inlet 1 and returns at the top, coating the 1.8-inch diameter and passes into an 8-inch diameter tube.

(16) Gases can escape from an outlet 4. The outlet 4 can include an exhaust gas outlet hatch that can be manufactured from metal, such as A 36 steel.

(17) As shown in FIG. 5, the insulation provided by the two sheets (IS) and (ES) can be perfectly observed through the present indentation.

(18) As shown in FIGS. 6-7 with continuing reference to the foregoing figures, the heat exchanger comprises a cold-water inlet 2, a hot water outlet 3, and an insulator A.

(19) FIG. 6 shows a division, which makes it a double circulation and all the heat that is generated is used at the bottom and at the top, and the heat is used again when the currents collide, that is to say, there is a double circulation in the gases and in the water.

(20) As shown in FIG. 7, a cold water section 5 holds cold water. A hot water section 6 holds hot water. A transition section 7 provides for the transformation of the cold water into hot water with the water circulating through the heat exchanger along a flow path 8.
