Definitions

  • the invention relates to a thermoelectric flexible mat, which is provided in particular for temperature-controlling a vehicle seat of a motor vehicle.
  • thermoelectric mat can be employed for this purpose.
  • the dew point of the ambient air is lowered as a result of which the water contained in the ambient air can condense. If the condensate is not discharged from the thermoelectric mat, the same can be wet through.
  • the object of the invention therefore is to state an improved or at least alternative embodiment for a thermoelectric flexible mat of the generic type, in which the described disadvantages are overcome.
  • thermoelectric flexible mat is provided in particular for temperature-controlling a vehicle seat of a motor vehicle and has a first large surface and a second large surface located opposite the first large surface.
  • the mat comprises p-doped and n-doped elements, which, alternating with one another, are electrically interconnected via electrically conductive conductor bridges to form a series circuit.
  • the elements can consist for example of a semiconductor material.
  • the respective conductor bridges of the series circuit are assigned at least in regions to the first large surface of the mat and the second large surface of the mat, so that the first large surface of the mat represents a hot side and the second large surface a cold side or vice versa.
  • the mat has an absorptive absorption structure, which connects the hot side and the cold side of the mat.
  • a liquid condensed or present on the cold side can then be absorbed into the absorption structure and, via the absorption structure, transported to the hot side.
  • the heat is absorbed and on the hot side the absorbed heat, plus the consumed electric power, dissipated.
  • the absorptive absorption structure connects the cold side and the hot side and can transport the liquid, through the capillary effect or through the Marangoni effect or through the suction effect on the cold side and transport the same through the capillary force to the hot side.
  • the liquid for example condensate or perspiration
  • the same is absorbed by the absorption structure and transported to the hot side of the mat.
  • the liquid from the absorption structure can evaporate and the evaporated liquid passed on into the surroundings.
  • the local transport away of the evaporated liquid can be convectively supported—for example by means of a fan or however by means of any device for the convective heat dissipation.
  • the absorption structure is not saturated with the liquid so that the liquid can be continuously transported from the cold side to the hot side and dissipated into the surroundings.
  • the liquid present or condensed on the cold side can be transported to the hot side and passed on into the surrounding air.
  • a wetting-through of the mat that can occur in an extreme case can thereby be prevented and the comfort of the passengers significantly increased.
  • No further moving parts are present and necessary in the mat so that the mat remains maintenance-free.
  • the absorptive absorption structure is comparatively cost-effective, so that the costs of the mat are not increased or only insignificantly so.
  • the installation space required by the mat is not increased or only insignificantly so.
  • the efficiency of the mat can be increased through the evaporating of the liquid on the hot side.
  • the mat is a fabric.
  • the fabric comprises a plurality of first threads and a plurality of second threads.
  • the second threads are preferentially electrically insulating.
  • the first threads then form the weft threads and the second threads form the warp threads of the fabric, or vice versa.
  • the first threads are alternately formed by p-doped and n-doped thread portions and electrically conductive first and second thread portions arranged in between.
  • the p-doped first thread portions form the respective p-doped P-elements of the mat and the n-doped first thread portions form the respective n-doped N-elements of the mat.
  • the second thread portions arranged in between then form the respective conductor bridges of the mat.
  • the term “thread” is chosen merely to better understand the structure of the fabric.
  • the second threads can be formed by foam material blocks of an electrically insulating foam material.
  • the first threads can be formed by wide flexible webs, which comprise p-doped, n-doped and electrically conductive web portions.
  • the fabric can then be formed in that the flexible webs are guided about the non-deformed or only slightly deformed foam material blocks or intertwined with these.
  • the respective web portions are arranged corresponding to the cold side or the hot side on the foam material blocks and between the adjacent foam material blocks.
  • the absorptive absorption structure can be formed independently of the embodiment by a plurality of absorption threads.
  • at least some of the absorption threads can extend between the cold side and the hot side perpendicularly to these.
  • the cross section of at least some of the absorption threads can be round or oval or quadrangular.
  • differently shaped cross sections of the absorption threads are also conceivable.
  • the diameter of at least some of the absorption threads can be between 0.5 mm and 1.5 mm.
  • At least some of the absorption threads can be braided of multiple individual threads.
  • at least some of the absorption threads can follow adjacent to the first threads of the fabric. It is also conceivable that at least some of the absorption threads are embedded into the second threads at least in regions. It is conceivable, furthermore, that at least some of the absorption threads are arranged between the adjacent second threads.
  • the same consists of hydrophilic fibres or of hydrophilic particles or of hydrophilic moulding compounds.
  • the absorptive absorption structure can be formed of conjugate fibres or of mixed spinning fibres or of staple fibres. It is conceivable that the absorptive absorption structure is formed of a non-woven fabric or of a fabric or of a knitted fabric or of a twisted cloth.
  • the absorptive absorption structure can be formed of hollow fibres or of solid fibres.
  • the absorptive absorption structure can consist of synthetic or natural organic materials or of inorganic materials or of a combination of these materials.
  • Possible synthetic organic materials are for example a viscose base, a cellulose base, polyolefin and a polyolefin base—in particular polyethylene, polypropylene, polybutene-1, polypentene-1 as well as statistical copolymers or block copolymers thereof, —polyester and a polyester base.
  • the natural organic materials cotton or hemp are conceivable for example.
  • ceramic can be employed for example.
  • the absorptive absorption structure can consist of two-part fibres having a core and a sheathing.
  • the core and/or the sheathing can consist of polyethylene or of polypropylene or of polyethylene-vinyl-acetate copolymerisate or of polyester in particular polyethylene terephthalate, polybutene terephthalate or polyethylene terephthalate isophthalate-copolymerisate or of polyamide, in particular of polyhexamethylene adipic acid amine.
  • Polyhexamethylene adipic acid amine is also known under the trademark nylon®. The hydrophilic nature depends on the mixing ratio between for example polyethylene and the phthalates and can thus be adjusted.
  • the absorptive absorption structure can consist of coated fibres. At least some components of the thermoelectric mat can be formed of a metal foam.
  • FIGS. 1 and 2 show sectional views of a thermoelectric material according to the invention with in each case a differently configured absorptive absorption structure.
  • FIGS. 1 and 2 show sectional views of a thermoelectric mat 12 according to the invention, in particular for temperature-controlling a vehicle seat of a motor vehicle.
  • the mat 12 is a thermoelectric fabric 1 .
  • the fabric 1 has a first large surface 13 a and a second large surface 13 b, which are arranged opposite one another.
  • the fabric 1 furthermore, comprises a plurality of first threads 2 —only one visible here—and a plurality of second threads 3 .
  • the first threads 2 form the warp threads 2 a and the second threads 3 the weft threads 3 a of the fabric 1 .
  • the first threads 2 are alternately formed by p-doped thread portions 4 and n-doped thread portions 5 as well as electrically conductive first thread portions 6 and electrically conductive second thread portions 7 arranged in between.
  • the first threads 2 of the fabric 1 thus constitute a series circuit.
  • the individual threads 2 can be electrically interconnected.
  • the first thread portions 6 are assigned to the first large surface 13 a and then form a hot side 8 of the fabric 1 and the second thread portions 7 are assigned to the second large surface 13 b of the fabric 1 and then form a cold side 9 of the fabric 1 .
  • the second threads 3 are preferentially electrically insulating.
  • the fabric 1 comprises an absorptive absorption structure 10 , which connects the hot side 8 and the cold side 9 .
  • the absorption structure 10 is formed of multiple absorption threads 11 .
  • the absorption threads 11 are orientated perpendicularly to the cold side 9 and to the hot side 8 and lie between the adjacent second threads 3 .
  • the heat is absorbed on the cold side 9 and on the hot side 8 , the absorbed heat plus the consumed electric power is then dissipated.
  • the absorptive absorption structure 10 connects the hot side 8 and the cold side 9 and can absorb the liquid—for example condensate or perspiration—present on the cold side 9 by way of the capillary effect or by way of the Marangoni effect or by way of the suction effect.
  • the absorbed liquid can be transported via the absorption threads 11 to the hot side 8 and evaporate there. Because of this, any wetting-through of the fabric 1 that can occur in an extreme case can be prevented.
