Embodiment Construction

[0022] The housing 10 encloses a housing interior 11 , to which a device 20 for reducing humidity is coupled. The device 20 comprises an intermediate space 21 delimited by an intermediate space wall 22 and a first membrane 24 as an inlet 23 and a second membrane 26 as an outlet 25 . A cooling device 27 is located in the intermediate space 21 . The intermediate space wall 22 is interrupted by an outlet line 28 .

[0023]It can be seen that the first membrane 24 adjoins the ambient air, wherein the first membrane 24 allows gas, and thus external air, to pass into the intermediate space 21 due to its selective permeability, however, in contrast to the liquid The intermediate space 21 is sealed. The gas now contained in the intermediate space 21 is cooled by the operation of the cooling device 27 so that the water vapor fraction of the gas condenses into water, wherein the condensed water is discharged to the environment via the discharge line 28 . A non-return valve (not shown...

Abstract

The invention relates to a method and a device (20) for reducing the humidity of a gas in a housing interior (11), in particular in a battery housing interior, wherein a gas is led through a first selectively permeable membrane (24) into an intermediate space (21) having the first selectively permeable membrane (24) as an inlet (23) and a second selectively permeable membrane (26) as an outlet, and the gas is then cooled in the intermediate space (21) by a cooling unit (27) such that a water vapor portion of the gas is condensed into water and the gas having a reduced water vapor content is directed through the second selectively permeable membrane (26) into the housing interior (11).

Description

technical field [0001] The invention relates to a method and a device for reducing the humidity of a gas in a housing interior, in particular a battery housing interior. [0002] Preferably, the method and the device are used for reducing the humidity in the interior of a housing in which battery cells or batteries are arranged. The battery cells and the batteries assembled from the battery cells form, in a known manner, one or more accumulators, which can be charged and discharged again. A battery cell is here an individual galvanic cell which, depending on the combination of materials of the electrodes of the cell, provides a characteristic voltage. The battery cells can be connected in series or in parallel with each other to form a battery. Background technique [0003] Recently, lithium-ion batteries in particular are more widely used in mobile phones, notebook computers and other portable electronic devices. Furthermore, lithium-ion batteries are increasingly used a...
