Description

Beschreibung. Zu den Elektro-Speicherheizgeräten gehören die, die Wärme durch natürliche Konvektion abgeben (Geräte mit Wä.rmluft-E.tladeklappen) und solche die Wärme durch erzwungene Konvektion abgeben (Geräte mit Ventilator). Die ersteren haben den Vorteil, daß sie keinen Ventilator benötigen und dadurch dessen Geräusch nicht haben. Ihr Nachteil ist der geringe Luftdurchsatz. Der Durchsatz der Luft ist abhängig von ihrer Auftriebskraft im Gerät, die sie durch die Aufheizung erhält. Man kann davon ausgehen, daß, die an der Speicherkern-"masse vorbeiströmende Luft, auf ihrem Weg gleichmäßig aufgeheizt wird. Das hat den Nachteil, daß z.B.. am oberen Ende des Speicherkerns die Luft eine dem Weg entsprechende Wärmemenge erhält, aber die Aufheizung der Luft an dieser Stelle keine nennenswerte, für die Größe des Luftdurchsatzes nützliche, Auftriebskraft liefert. Eine Verbesserung ist anzustreben. Dadurch, daß der durch das Gerät strömende Luft die gesamte Wärme - außer die durch die Isolierung abgeleitet wird -, an einer möglichst tiefen Stelle zugeführt wird, um sie optimal, zur Erreichung einer möglichst großen Auftriebskraft im Gerät, zu nutzen. Die benötigten, an die Luft wärmeabgebende, Oberflächen, sind räumlich zusammengezogen und bilden einen Wärmeaustauscher. Der Wärmetransport zu diesen erfolgt durch Wärmeleitung, z.B. unter Verwendung von Metall. Abb. A und B zeigen ein, im Querschnitt bzw. Längsschnitt dargestelltes, Gerät mit diesen Verbesserungen. Hierin ist: 1 Gehäuse, 2 Luftaustritt, 3 Kühlluftkanal, 4 Warmluftkanal, 5 Lufteintritt, 6 Wärmeentladeklappe, 7 Wärmeaustauscher, 8 Isolierung, 9 Speicherkernsteinplatten, 10 Speicherkerngußplatten. Vorteile.Description. Electric storage heaters include those that Giving off heat through natural convection (devices with warm air discharge flaps) and those that give off heat through forced convection (devices with a fan). The former have the advantage of not requiring a fan and thereby not have its sound. Their disadvantage is the low air flow. The throughput The air is dependent on its buoyancy in the device, which it heats up receives. It can be assumed that the mass flowing past the storage core Air, is heated evenly on its way. This has the disadvantage that e.g. At the upper end of the storage core, the air receives an amount of heat corresponding to the path receives, but the heating of the air at this point is not worth mentioning for the Size of air flow useful, provides buoyancy. One improvement is to strive for. Because the air flowing through the device absorbs all of the heat - except that is diverted through the insulation - at as deep a point as possible is fed to it optimally, to achieve the greatest possible buoyancy in the device. The surfaces required to give off heat to the air are spatially contracted and form a heat exchanger. The heat transport too this takes place through thermal conduction, e.g. using metal. Fig. A and B show a device with these improvements, shown in cross-section or longitudinal section. Here is: 1 housing, 2 air outlet, 3 cooling air duct, 4 warm air duct, 5 air inlet, 6 heat discharge flap, 7 heat exchanger, 8 insulation, 9 storage core stone plates, 10 memory core cast plates. Advantages.

1. Eine hohe Auftriebskraft innerhalb des Gerätes.1. A high buoyancy within the device.

2. Die Zuführung kalter Mischluft erfolgt an günstiger, weil tiefer Stelle.2. The supply of cold mixed air is cheaper because it is deeper Job.

3. Hoher Luftdurchsatz.3. High air flow.

4. Geringe Luftaustrittstemperatur.4. Low air outlet temperature.

5. Bedingt durch die hohe Auftriebskraft und durch die Konstruktion, kann der Luftaustritt tiefer erfolgen, z.B. in Höhe a; die Bedingungen sind dann beim Anordnen des Gerätes unter einem Fenster, wegen dem geforderten Vorhang-Ausblass-Abstand günstiger.5. Due to the high buoyancy and the construction, the air outlet can be deeper, e.g. at height a; the conditions are then when arranging the device under a window, because of the required curtain blow-out distance cheaper.
