Abstract
(EN)
The present invention relates to a high-capacity ceramic heater for an electric car and a method for manufacturing same. The above-mentioned high-capacity ceramic heater for an electric car according to the present invention is a ceramic heater having silicon nitride as a main material thereof, the ceramic heater comprising: 90-95 parts by weight of Si3N4; 3-5 parts by weight of Y2O3; 2-5 parts by weight of Al2O3; and 1-3 parts by weight of Ti. The high-capacity ceramic heater for an electric car configured as described above and the method for manufacturing same provide industrially useful operational effects as follows: silicon nitride is used as a main component, a sub component is mixed therewith at a predetermined ratio, and a specific method is used for shaping, thereby manufacturing the ceramic heater. Accordingly, the heater has improved durability and reliability, and the car thus has excellent resistance to vibration and excellent high-temperature mechanical characteristics, such as thermal impact property, bending strength, Vickers hardness, fracture toughness, and the like, such that, even when driven at a full voltage of DC 360-600 V, same operates stably. The resistance value can be precisely controlled according to a specific driving voltage. Compared with conventional sheath heaters, a reduced number of heaters can be mounted, thereby reducing the weight of the car and the volume of the heating module. As a result of excellent heating characteristics and long lifespan, it is possible to accomplish higher efficiency, higher stability, and less weight compared with conventional heating modules. As such, the above-mentioned problem of the prior art is resolved, thereby improving the fuel efficiency and stability of hydrogen fuel electric cars.

La présente invention concerne un dispositif de chauffage en céramique à haute capacité pour une voiture électrique et son procédé de fabrication. Le dispositif de chauffage en céramique à haute capacité pour une voiture électrique mentionné ci-dessus selon la présente invention est un dispositif de chauffage en céramique ayant du nitrure de silicium en tant que matériau principal de celui-ci, le dispositif de chauffage en céramique comprenant : 90 à 95 parties en poids de Si3N4 ; 3 à 5 parties en poids d'Y2O3 ; 2 à 5 parties en poids d'Al2O3 ; et 1 à 3 parties en poids de Ti. Le dispositif de chauffage en céramique à haute capacité pour une voiture électrique configuré comme décrit ci-dessus et son procédé de fabrication fournissent des effets opérationnels utiles industriellement comme suit : du nitrure de silicium est utilisé en tant que composant principal, un sous-composant est mélangé avec celui-ci à un rapport prédéterminé, et un procédé spécifique est utilisé pour la mise en forme, ce qui permet de fabriquer le dispositif de chauffage en céramique. Par conséquent, le dispositif de chauffage présente une durabilité et une fiabilité améliorées, et la voiture présente ainsi une excellente résistance à la vibration et d'excellentes caractéristiques mécaniques à haute température, telles qu'une propriété d'impact thermique, la résistance à la flexion, la dureté Vickers, la ténacité, etc, de telle sorte que, même lorsqu'elle est entraînée à une tension complète de 360 à 600 V CC, celle-ci fonctionne de façon stable. La valeur de résistance peut être commandée avec précision en fonction d'une tension d'entraînement spécifique. Par rapport aux dispositifs de chauffage à gaine classiques, un nombre réduit de dispositifs de chauffage peuvent être montés, ce qui permet de réduire le poids de la voiture et le volume du module de chauffage. En conséquence d'excellentes caractéristiques de chauffage et une longue durée de vie, il est possible d'atteindre un rendement plus élevé, une stabilité plus élevée et moins de poids par rapport aux modules de chauffage classiques. Ainsi, le problème mentionné ci-dessus de l'état de la technique est résolu, ce qui permet d'améliorer l'efficacité et la stabilité du carburant des voitures électriques à combustible à hydrogène.
