FR2493498A1 - Unit for recovering energy from fluid - circulating into and out of container filled with numerous spheres - Google Patents

Abstract

The energy recovering unit has a receptacle in which is sent a fluid. This circulates between spheres and leaves having given heat or cold. The receptacle acts as the accumulator and the spheres create many thermal bridges. The arrangement uses less energy than normal and is based on the better relationship surface/vol/wet. of a sphere. The fluid has better circulation in the paths between the spheres and heat exchange between fluid and spheres is good. Filling the receptacle with spheres is a simple matter.

Description

 The present invention relates to "an energy recuperator by fluid circulation".

 The Recuperator allows, thanks to a core composed of spheres accumulating energy inside a container, to transmit and restore a heat or refrigeration exchange to a fluid.

Known devices of this kind in which a fluid circulates are
- simple empty bins or containers.

 - horizontal, vertical or spiral coils.

 These simple systems, large consumers of energy, have very little inertia of restitution.

 Variants have been made, either by creating artificial baffles or by inserting a solid cylindrical core in a tube, in order to provide more restitution inertia.

 Such devices do not allow stretching used in all systems and do not draw the quintessence of the energy to be restored.

 The recuperator according to the invention makes it possible to transmit and restore an exchange, either heat or refrigeration, using less energy.

 Knowing that the best surface / volume / mass ratio is the sphere, it is therefore a question of filling a container of any shape and material, having an inlet and an outlet for the fluid, with empty or full spheres. of any shape and material.

The spheres, in contact with the interior walls of the container will thus create
- a maximum of thermal bridges between the spheres and between the container and the spheres.

 - better circulation of the fluid in natural baffles allowing maximum friction.

 - greater and better thermal distribution between the material and the fluid.

 - a greater and better heat or refrigeration accumulation thanks to the inertia of the mass of the spheres.

 - greater ease of implementation by filling a ball container.

 - great ease of repair.

 - energy saving.

 The accompanying drawings represent the choice of one of the many possible containers.

 A portion of cylindrical tube in cross section and in longitudinal section.

 As shown, the recuperator comprises a hollow cylindrical tube (1) filled with spherical balls (2) in which and around which circulates a fluid entering through an orifice and leaving through another orifice.

 The recuperator object of the invention can be used in all cases where there is a need to save energy to transmit and restore a heat or refrigeration exchange.

 Interesting applications can be used in the fields of heating, filters, natural baffles and refrigeration.

Claims (1)
