  • the humidifier proposed therein has a humidifier block with a plurality of moisture-permeable membranes.
  • the humidifier block is traversed within the membrane by a first gas and outside the membrane by a second gas, wherein the moisture-permeable design of the membranes allows a moisture exchange between the gases.
  • a spacer is provided which completely fills the humidifier block outside the membranes or is arranged between the membranes in layers or layers.
  • a disadvantage of such a realization of the humidifier is in particular the complex production of the humidifier.
  • the humidifier block layer by layer must be piled up in order to realize the desired arrangement of the membranes in the humidifier. Furthermore, both the filling and the layer-shaped configuration of the spacer reduce the permeability of the humidifier block, in particular gas flowing outside of the membrane, resulting in a correspondingly reduced exchange of moisture between the gases.
  • the present invention therefore deals with the problem of providing for a method for producing a humidifier block of the aforementioned type and for such a humidifier block and an associated humidifier improved or at least other embodiments, in particular by a simple and / or cost-effective production and / or characterized by increased efficiency.
  • the present invention is based on the idea of using a quasi-endless, belt-like carrier to make a humidifier block, which is equipped with membranes and then shaped to form the humidifier block. This eliminates in particular a stacking of the membranes and the use of appropriate spacers, which makes the production of the humidifier faster and / or cheaper.

  • the jacket of the membranes is moisture permeable to moisture exchange.
  • at least one of the carriers of the humidifier block is equipped with a plurality of membranes. The loading of the carrier takes place in such a way that the membranes are arranged in a longitudinal direction substantially parallel to each other and on the carrier side by side. Thereafter, the carrier with the membranes, that is, the carrier equipped with the membranes, molded to the humidifier block.
  • At least one such humidifier block is produced by molding such a membrane-mounted carrier according to the concept of the invention.
  • the carrier has a corresponding size, in particular a length extending transversely to the longitudinal direction. This can be realized, for example, by cutting the carrier to the desired length before molding. It is conceivable It also means to separate or cut the carrier after molding upon reaching a desired size of the humidifier block.
  • the membranes are fixed on the associated carrier.
  • a fixation of the membranes is realized, for example, in that the carrier is adhesive.
  • the carrier may have a corresponding adhesive layer.
  • the at least one carrier is formed like a strip. That is, the carrier may be configured as a strip. In an adhesive embodiment of the carrier, the carrier can thus be realized as an adhesive strip.
  • the shaping of the carrier with the membranes to the humidifier block is in principle conceivable in any way, provided that the membranes are then arranged side by side in the transverse direction and in the height direction.
