Definitions
- 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 a phase change material generally comprises an enclosure inside which is placed the phase-change material generally in encapsulated form and inside which circulates a coolant.
- the performance of the thermal battery is dependent on several parameters, in particular the quantity of phase-change material that it can contain, as well as the requirement for circulation of the fluid within the tank with the lowest pressure drops. possible.
- Another parameter may be the amount of exchange surface between the heat transfer fluid and the encapsulated phase change material and the exchange time during which they remain in contact.
- 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 at least one inlet and at least one fluid outlet and comprising within it a phase-change material encapsulated in the form of tubes, said tubes being arranged parallel to one another, said thermal battery comprising at least one spacer of at least a portion of the tubes, said at least one spacer which divides the inside of the thermal battery into at least two fluid circulation zones, a first circulation zone comprising the fluid inlet and a second circulation zone comprising the fluid outlet, said thermal battery further comprising a passage of the fluid between two successive zones of culation at each spacer.
- the spacers thus form obstacles to the flow of fluid in the enclosure. Thanks to the fluid passages, said spacers form baffles of a circulation circuit which increases the distance traveled during which the fluid is in contact with the tubes and therefore where the fluid can exchange heat energy with the phase change material. . In addition, the spacers allow the maintenance and constant spacing of the tubes in the enclosure.
- said at least one spacer is made of a material impermeable to fluid.
- said thermal battery comprises at least two spacers and the fluid passages at two successive spacers are arranged opposite to each other.
- the spacer or spacers are truncated plates of complementary shape to the inner shape of the enclosure and whose truncation forms the passage of the fluid, said truncated plates having tube orifices inside. of which tubes are inserted.
- the truncated plates are in one piece.
- the truncated plates comprise a stack of cylinder doors, said cylinder doors having semicircular notches on an upper face and a lower face, the semicircular notches on the underside of a door. cylinder completing the semi-circular notches of the upper face of the adjacent cylinder door so as to form the tube orifices once said cylinder gates are stacked.
- the spacer comprises a stack of cylinder doors, makes it easy to modulate the height of the truncation and therefore the size of the fluid passage by stacking more or less cylinder doors.
- the tube orifices are aligned as well in abscissa as in ordinate according to a reference in two dimensions.
- the semicircular notches of the lower and upper faces of the same cylinder door are arranged in alignment with each other.
- the tube orifices are aligned on the abscissa and arranged in staggered rows along the ordinate in a two-dimensional reference.
- the semi-circular notches of the lower and upper faces of the same cylinder door are arranged in staggered rows.
- the cylinder gates are assembled together by a tongue-and-groove connection.
- the inner wall of the enclosure comprises at least one fixing groove, each spacer being fitted into a dedicated fixing groove.
- FIG. 1 shows a schematic representation in side section of a thermal battery
- FIG. 2 shows a diagrammatic representation in front section of a thermal battery according to one embodiment of the invention
- FIG. 3 shows a diagrammatic representation in front section of a thermal battery according to another embodiment of the invention
- FIG. 4 shows a schematic front view of a truncated plate
- FIG. 5 shows a diagrammatic representation in front section of a thermal battery according to yet another embodiment of the invention
- FIG. 6 shows a schematic front view of a section of a cylinder door according to a first embodiment. realization
- Figure 7 shows a schematic front view of a section of a cylinder door according to a second embodiment.
- FIG. 1 shows a thermal battery 1 comprising an enclosure 100 in which a fluid circulates between at least one inlet 3a and at least one outlet 3b of fluid.
- the thermal battery 1 comprises within it an encapsulated phase-change material 5, the fluid passing between the different capsules.
- the material to Encapsulated phase change can for example be implemented in the form of tubes. It is also possible to use tubes filled with phase change material.
- Said tubes 5 are in particular arranged parallel to each other in the enclosure 100.
- the thermal battery 1 comprises at least one spacer 7 disposed in the enclosure 1 00, in order to separate and maintain at least the tubes 5. Said at least one spacer 7 divides the inside of the thermal battery 1 into at least two fluid circulation zones 9a, 9b.
- a first circulation zone 9a comprises the fluid inlet 3a and a second circulation zone 9b comprises the fluid outlet 3b.
- Said spacer 7 can also be considered as a separation and holding device. Indeed, it separates and defines the circulation zones 9a, 9b and holds the tubes 5 in place at a constant distance from one another.
- the spacer or spacers 7 are preferably made of an impervious material, for example of metal material, polymer or plastic. So that the fluid can pass from one circulation zone 9a, 9b to another, the thermal battery 1 comprises a passage 11 of the fluid between two successive circulation zones 9a, 9b at each spacer 7, for example an opening made in the spacer 7.
- the thermal battery 1 comprises three spacers 7 in its enclosure 100.
- the thermal battery 1 then comprises four fluid circulation zones, a first circulation zone 9a through which the fluid arrives, two zones intermediate circulation 9c and a second circulation zone 9b through which the fluid is evacuated.
- a thermal battery comprising more or less four fluid circulation zones, the number of said fluid circulation zones depending on the number of separation and holding means 7 in the enclosure 100 of the thermal battery 1.
- the spacers 7 thus form obstacles to the flow of fluid in the chamber 100.
- said spacers 7 form baffles of a circulation circuit which increases the distance traveled during which the fluid is in contact with the tubes 5 and so where the fluid can exchange energy heat with the phase change material. Furthermore the spacers 7 allow the maintenance and constant spacing of the tubes 5 in the enclosure 100.
- the fluid passages 11 at two successive spacers 7 are preferably arranged opposite to each other. This configuration allows a maximum elongation of the fluid path within the thermal battery 1.
- the spacer (s) 7 may be truncated plates.
- truncated plate is meant that the spacers 7 are formed of a plate of complementary shape to the inner shape of the enclosure 100 and is disposed within said enclosure 100 perpendicular to its inner wall.
- This plate is truncated and this truncation 70 forms the passage 11 of fluid which allows the circulation of said fluid between two successive circulation zones.
- said truncated plates comprise tube orifices 71 (visible in FIG. 4) inside which tubes 5 are inserted.
- the height at which the truncation is located makes it possible to modulate the length of circulation of the fluid in the thermal battery 1 and also makes it possible to apply a greater or lesser amount of pressure drop to said fluid. It is thus necessary to determine a compromise between the length of circulation within the thermal battery 1, which must be as long as possible, and the pressure drops, which must be as low as possible.
- the inner wall of the enclosure 1 00 may comprise at least one fixing groove (not shown in the various figures), each spacer 7 being fitted into a dedicated fixing groove in order to be fixed and held in the enclosure 100.
- the spacer or spacer 7 can also be fixed by gluing or welding whether there is a fixing groove or not.
- a seal can be implemented.
- the tube orifices 71 can be aligned as well in abscissa as in ordinate according to a reference in two dimensions.
- the orifices 7 1 of tube may be aligned on the abscissa and arranged in staggered rows along the ordinate in a two-dimensional reference.
- this marker may for example be an orthogonal reference.
- the separation and holding means 7, illustrated in Figures 2 to 4 are truncated plates in one piece.
- the truncated plate is formed by a plain plate and in one piece, said plate having orifices 71 of tube for holding the tubes 5.
- this plate truncated in one piece may have semicircular notches 72 at its truncation 70 to support and maintain the spacing between the tubes 5 of a last alignment.
- the latter comprise a stack of cylinder doors 73
- These cylinder doors 73 are shown in more detail in Figures 6 and 7.
- These cylinder doors 73 are strips of which stacking allows the formation of a truncated plate.
- the length of the cylinder doors 73 is chosen such that their stack allows the formation of a truncated plate whose shape is complementary to the enclosure 100.
- These cylinder doors 73 comprise semicircular notches 72 on an upper face and a face lower.
- the semicircular slots 72 on the underside of a cylinder door 73 complete the semicircular slots 72 of the upper face of the adjacent cylinder door 73 to form the tube orifices 71 once said cylinder doors 73 are stacked. .
- FIG. 7 thus shows a cylinder door 73 in a case where the tube orifices 71 of a spacer 7 are aligned as well on the abscissa as on the ordinate according to a two-dimensional mark.
- the semicircular notches 72 of the lower and upper faces of the same cylinder holder 73 are disposed plumb with each other.
- FIG. 6 thus shows a cylinder door 73 in a case where the tube orifices 71 of a spacer 7 are aligned on the abscissa and arranged in staggered rows along the ordinate in a two-dimensional reference.
- the semi-circular notches 72 of the lower and upper faces of the same cylinder holder 73 are arranged in staggered rows.
- said cylinder doors 73 can be assembled together by a tongue-and-groove connection.
- the cylinder doors 73 can also be fixed together by gluing or welding and a seal can also be placed to seal.
- spacers 7 allows the formation of baffles in the circulation of the fluid passing through the thermal battery 1 and thus lengthens the distance where said fluid is in contact with the phase change material.
- spacers 7 allow a maintenance and a constant spacing of the tubes 5 in the enclosure 100.
