Embodiment Construction

[0043] figure 1 An example of a thermoelectric textile 1 for a vehicle seat of a motor vehicle is shown in a plan view of the underside 22 of the textile 1 in viewing direction B1. The fabric 1 comprises: a conductive first thread 2 consisting of p-doped and n-doped thread portions 4N, 4P and a first thread portion 5a and a second thread portion 5b arranged therebetween (which are formed to be conductive) Alternately formed. The first thread portion 5 a forms the hot side 20 of the fabric 1 on the underside 22 of the fabric 1 . The second thread portion 5b is on the top side 23 (on the underside of the fabric 1 figure 1 The cold side 21 of the fabric 1 is formed on the plan view not visible).

[0044] In addition, the fabric 1 comprises electrically insulating second threads 3 . In the example in the figures, the first threads 2 form the warp threads 6 of the fabric 1 and the second threads 3 form the weft threads 7 of the fabric 1 . However, in a variant, the opposite sp...

Abstract

A thermoelectric fabric 1 may include a plurality of first threads 2 and second threads 3. The first threads 2 may be alternately formed by p-doped and n-doped thread portions 4N,4P and electrically conductive first thread portions and second thread portions 5a,5b arranged in between. The first thread portions 5a may form a hot side 20 of the fabric 1, and the second thread portions 5 may form a cold side 21. The first threads 2 may form the warp threads 6 of the fabric 1, and the second threads may form the weft threads 7 of the fabric 1. What is important for this fabric 1 for the present invention is a temperature control structure 8 having a plurality of temperature control elements 19. These temperature control elements 19 are arranged on the first wire portion 5a forming the hot side20.

Description

technical field [0001] The present invention relates to a thermoelectric fabric that can be used for temperature control of various components of a motor vehicle. The fabric is particularly suitable for temperature control of vehicle seats of motor vehicles. [0002] In addition, a thermoelectric device having such a thermoelectric fabric is included. The invention furthermore relates to a vehicle seat having such a thermoelectric device and to a motor vehicle having at least one such thermoelectric seat. Background technique [0003] A thermoelectric element of a thermoelectric device includes a thermoelectrically active semiconductor material that converts a temperature difference into a potential difference, ie, voltage, and vice versa. In this way, heat flow can be converted into electric current and vice versa. Thermoelectric elements are based on the Peltier effect when converting electrical energy into heat and the Seebeck effect when converting heat into electrica...
