Abstract

A heat exchanger for exchanging heat between two fluids comprises a first chamber 10 through which a first fluid X flows, a second chamber 20 through which a second fluid Y flows, and a graphene foam structure 40 extending from the inside of the first chamber to the inside of the second chamber to conduct heat from the first fluid to the second fluid. Each chamber may comprise an inlet 11, 21 and an outlet 12, 22. A plastics or rubber common wall 30 may separate the chambers. The chambers may be side by side or one inside the other, i.e. coaxially (Fig 2). The graphene structure may be rings.

Description

Title: Heat Exchanger The present invention relates to a heat exchanger.
According to the present invention there is provided a heat exchanger for exchanging heat between two fluids comprising: a) a first chamber through which flows a first fluid, b) a second chamber through which flows a second fluid, c) a graphene foam structure extending from the inside of the first chamber to the inside of the second chamber to conduct heat from one fluid in the first chamber to a second fluid in the second chamber.
Preferably the first and second chambers have fluid inlet and outlet pipes.
The first and second chambers may be separated by a common wall through which the graphene foam extends. The common wall may be plastic or rubber.
In one embodiment the chambers are in side by side relationship.
In another embodiment the one chamber is inside another chamber.
Embodiments of the invention will now be described with reference to the accompanying drawings.
Referring to Figure 1 there is shown a heat exchanger 1 for exchanging heat between two fluids, which could be gas or liquids or combinations thereof.
A first chamber 10 is provided with an inlet pipe 11 and an outlet pipe 12 through which flows a first fluid X. A second chamber 20 is provided with and inlet pipe 21 and an outlet pipe 22 through which flows a second fluid Y The first and second chambers are in side by side relationship and separated by a common wall (e.g. of rubber or plastics) through which a graphene foam structure in the form of rings 40 extend. The graphene foam rings 40 thus extending from the inside of the first chamber 10 to the inside of the second chamber 20; In use the rings 40 conduct heat from one fluid X in the first chamber 10 to a second fluid Y in the second chamber 20 (or vice versa depending on which fluid is honest) so heat is exchanged between the fluids.
Structures other than foam rings may be used.
Referring now to Figure 2, there is shown a heat exchanger 50 for exchanging heat between two fluids, which could be gas or liquids or combinations thereof.
A first chamber 60 is provided with an inlet pipe 61 and an outlet pipe 62 through which flows a first fluid X. A second chamber 70 is provided with and inlet pipe 71 and an outlet pipe 72 through which flows a second fluid Y The first and second chambers are co-axially aligned with chamber 60 inside chamber 70. The chambers are separated by a common wall fonned by the wall of chamber 60 (e.g. of rubber or plastics) through which a graphene foam structure in the form of rings 80 extend. The graphene foam rings 80 thus extending from the inside of the first chamber 60 to the inside of the second chamber 70.
In use the rings 80 conduct heat from one fluid X in the first chamber 60 to a second fluid Y in the second chamber 70 (or vice versa depending On which fluid is hottest) so heat is exchanged between the fluids.
Structures other than foam rings may be used.
The graphene conducts heat rapidly so making the heat exchanger of the invention very efficient.
The heat exchanger may be made of any suitable material, such as plastic or rubber.
The inventiOn may take a form different to that specifically described above.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
