Embodiment Construction

[0031] Table 1 shows the material specifications of an exemplary planar evaporator according to the invention. Accordingly, the planar evaporator is formed from six layers, namely: a metal film and five wire fabrics sintered thereon. The metal consists in this example of the heat-conducting alloy NiCr8020, DIN material number 2.4869. Of course, other thermally conductive alloys can also be used. Thermally conductive alloys are available as prefabricated materials from ThyssenKrupp VDM GmbH, www.thyssenkruppvdm.de, which can then be processed into films, ultrafine wires and wire fabrics. The company ThyssenKrupp VDM GmbH offers the aforementioned material NiCr8020 under the trade name "Cronix 80", DIN material number 2.4869, which can also be smelted in very pure grades with a carbon content of The company KG www.spoerl.de routinely interweaves wire fabrics.

[0032] The metal foil and the wire fabric layers are bonded to each other by sintering. Sintering is preferably per...

Abstract

The invention relates to a planar evaporator, comprising a planar electrical resistance heating element for heating and evaporating a substance, which is or can be distributed on the heating element surface and which can be taken by inhalation, in a pulsed manner by means of an electrical heating current that flows or can flow in a planar manner through the resistance heating element, the resistance heating element having at least two electrical contacts or poles (2, 3) for introducing the heating current into the resistance heating element, wherein the resistance heating element has at least one slotted recess (5), which constricts the field lines (4) of the original electrical field that is or can be formed between the poles (2, 3), and is connected in a planar manner to an open-cell pore structure that accommodates or can accommodate the substance.

Description

technical field [0001] The invention relates to a planar evaporator comprising planar resistive heating elements for pulse-like heating and evaporating distributed in or can be A substance distributed on the surface of the heating element and respirably received has at least two electrical contacts or poles for conducting a heating current into the resistive heating element. Background technique [0002] Concept definition: [0003] The term "inhalably receivable substance" includes in principle every substance which can be inhaled by a person or user. The vaporized substance can be provided to the user in the form of a vapor-air mixture and / or a condensed aerosol. The substance may contain a drug, or consist of a pharmaceutical preparation, but the substance may also contain only components not declared to be a drug. [0004] "Pulse heating and vaporization" means that the substance is heated and vaporized within the time period of inhalation, ie within seconds or fracti...
