Definitions
- Encapsulated phase change material thermal battery and method of manufacturing the same are Encapsulated phase change material thermal battery and method of manufacturing the same.
- the present invention relates to the field of thermal batteries and more specifically the thermal batteries comprising a phase change material.
- Thermal batteries are generally used for heating the passenger compartment, in particular in electric and hybrid vehicles or for preheating a heat transfer fluid in a thermal management circuit. Thermal batteries can also be used for preheating engine oil or automatic gearbox oil of internal combustion engine vehicles.
- a thermal battery with phase-change materials generally comprises an enclosure forming a tank inside which is placed the phase-change material generally in encapsulated form.
- the performance of the thermal battery is thus dependent on the amount of phase change material that it can contain coupled with the requirement of a circulation of fluid within the tank with the lowest possible pressure drops.
- An object of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide an improved thermal battery.
- the present invention therefore relates to a thermal battery comprising an enclosure comprising an inlet and a fluid outlet and comprising within it tubes of material with a change of encapsulated phase, said tubes being arranged parallel to the flow of fluid flow, said thermal battery further comprising a device for holding and spacing the tubes of encapsulated phase change material, said holding and spacer device being disposed between the tubes themselves and between the tubes and the enclosure, said holding and spacer device being porous.
- the holding device and spacing is porous and is disposed between the tubes themselves and between the tubes and the enclosure allows optimum retention of said tubes within the enclosure and also allows circulation fluid in the thermal battery with limited pressure losses.
- the holding device and spacer comprises at least one rigid grid, the tubes passing through the mesh of said grid.
- the holding and spacer device comprises at least two grids and that said grids are kept at a distance from each other by means of fixing or locking said grids against the enclosure.
- the holding device and spacing comprises at least two grids and said grids are kept at a distance from one another by means of spacers.
- the holding device and spacer comprises a foam placed within the enclosure and surrounding the tubes.
- the foam has a porosity of between 50 to 95%.
- the present invention also relates to a method of manufacturing a thermal battery comprising encapsulated phase change material tubes, said method comprising a step of placing the encapsulated phase change material tubes within a device. maintaining and spacing porous.
- the step of placing the tubes consists of inserting said tubes in the meshes of at least one rigid grid.
- the step of inserting the tubes in the meshes of at least one rigid grid is preceded by a step of placing the at least one rigid grid within the enclosure of the thermal battery.
- the step of inserting the tubes in the meshes of at least one rigid grid is carried out outside the enclosure and that the method comprises an additional step of setting up the together formed by said tubes and the at least one rigid grid within the enclosure of the thermal battery.
- the step of placing the tubes consists of placing said tubes in a foam.
- the step of placing the tubes in a foam comprises a first stage of installation of the foam within the enclosure of the thermal battery and a second stage of insertion of the tubes within said foam.
- the step of placing the tubes in a foam comprises a first stage of installation of the tubes in the enclosure of the thermal battery and a second stage of installation of the foam at within the enclosure so as to surround said tubes.
- FIG. 1 shows a schematic representation in perspective of a section of a thermal battery according to a first embodiment
- FIG. 2 shows a schematic representation in perspective of the internal elements of a thermal battery according to a second embodiment.
- FIG. 1 shows a diagrammatic representation in section of a thermal battery 1 comprising an enclosure 3 comprising an inlet and a fluid outlet (not shown).
- the chamber 3 comprises within it tubes 5 of encapsulated phase change material.
- the tubes 5 are preferably arranged parallel to the flow flow of the fluid (represented by arrows).
- the thermal battery 1 further comprises a device for holding and spacing the tubes 7 of encapsulated phase change material.
- the holding and spacer device 7 is disposed between the tubes 5 themselves and between the tubes 5 and the enclosure 3. In order to allow the circulation of the fluid through the thermal battery 1, the holding device and the Spacer 7 is porous.
- the holding and spacer device 7 comprises a foam placed inside the enclosure and surrounding the tubes 5. It is an expanded foam of the polyurethane type, Low density polyethylene or metal with open cells to allow fluid flow. In order to have a circulation of the fluid through the thermal battery with the least possible loss of charge, the porosity of the foam is preferably between 50 and 95%.
- the foam preferably completely fills the enclosure 3 in order to obtain a good hold of the tubes 5.
- the holding device and spacing 7 comprises at least one rigid grid, the tubes 5 then pass through the mesh of said rigid grid to be maintained.
- the holding and spacer device 7 comprises at least two grids each placed at one end of said tubes 5. These grids are kept at a distance from each other by means of fixing or locking said grids against the enclosure 3. These means are for example a bonding, soldering or the presence of stops on the inner wall of the enclosure 3 so that the grids are not displaced during the circulation of the fluid within the thermal battery.
- the grids can also be kept at a distance from one another by means of spacers placed between them.
- the present invention also relates to the method of manufacturing the thermal battery 1 comprising tubes 5 of encapsulated phase change material. This method then comprises a step of placing the tubes 5 of encapsulated phase change material in a porous holding and spacer device 7.
- this step of placing the tubes 5 within the porous holding and spacer device 7 consists of placing said tubes 5 in a foam.
- the step of placing the tubes 5 in the foam may comprise a first step of installing the foam within the chamber 3 of the thermal battery 1 and a second step of insertion of the tubes (5) within of said foam.
- the step of placing the tubes 5 in the foam comprises a first step of installing the tubes 5 in the enclosure of the thermal battery and a second stage of installation of the foam within the enclosure 3 so as to surround said tubes 5.
- the installation of the foam within the chamber 3 can be carried out by injecting and expanding said foam directly into the chamber 3 or by introducing a preformed foam into the chamber 3 .
- the step of placing the tubes 5 inside the porous holding and spacer device 7 consists of inserting said tubes 5 into the meshes of at least one rigid grid .
- This step of insertion of the tubes 5 into the meshes of at least one rigid grid may be preceded by a step of placing the at least one rigid grid within the enclosure 3 of the thermal battery 1. tubes 5 are then inserted into the meshes of at least one grid inside the chamber 3.
- the step of insertion of the tubes 5 in the meshes of at least one rigid grid is performed outside the chamber 3.
- the method then comprises an additional step of setting up the assembly formed by said tubes 5 and the at least one rigid grid within the enclosure 3 of the thermal battery 1.
