HEAT ACCUMULATOR

[Category : - MECHANICAL ENGINEERING- CHEMISTRY]
[Viewed 243 times]



This invention can be used in many fields in wich a very fast transistion fase from liquid to gas or from gas to liquid is required.

A obvious fluidum is water to steam/steam to water but also other fluidums can be used.

In many cased the traditional use of a boiler can be replaced by this patented technology in order to heat/cool a fluidum past it's transistion stage.


CLAIMS(14)
A heat accumulator (1) for vaporizing fog liquid in a fog generator, characterised in that the heat accumulator comprises multiple closely contiguous, parallel oriented rods (2) with a diameter between 0.2 mm and 15 mm.
The heat accumulator according to claim 1 wherein the rods comprise a massive metal core.
The heat accumulator according to claim 1 further comprising inert beads around and/or between the rods.
The heat accumulator according to claim 3 wherein the average diameter of the beads is larger than 0.16 times the diameter of the rods.
The heat accumulator according to one of the previous claims, wherein the rods have a diameter of between 0.5 mm and 5 mm, in particular between 0.5 mm and 3.0 mm.
The heat accumulator according to one of the previous claims, wherein the rods at least partially comprise of corrosion-resistant material.
The heat accumulator according to one of the previous claims, wherein the rods are located in a container (9) and wherein the internal volume of the container is filled for more than 70% by the rods.
The heat accumulator according to claim 7, wherein the internal volume of the container, measured at the rods, is filled for more than 75% by the rods.
The heat accumulator according to one of the previous claims, wherein the rods are stacked hexagonally.
The heat accumulator according to one of the previous claims, comprising at least 7 rods, preferably at least 20 rods.
The heat accumulator according to one of the previous claims, further comprising a distribution agent (5)
A method to generate dense, opaque fog, the method comprising the following steps:
- heating the heat accumulator (1) according to any one of the previous claims;
- introducing a fog generating liquid into the heat accumulator via an inlet (3) in the heat accumulator, whereby the fog generating liquid is converted into a gaseous form; and
- letting the gas obtained flow out via an outlet (4) of the heat accumulator through which it generates a dense, opaque fog as soon as it gets in the atmospheric environment.
A fog generator comprising of a reservoir that comprises a fog generating liquid and a heat accumulator according to one of the claims 1 to 10.
The fog generator according to claim 13, wherein the reservoir comprising the fog generating liquid comprises a movable wall with the fog generating liquid on a first side of the wall and a propellant on a second side of the movable wall.
