Le corps chauffant est utilisé pour chauffer l'air s'écoulant dans le conducteur de chaleur par l'intermédiaire des extrémités d'entrée d'air, et l'air chauffé s'écoule hors des extrémités de sortie d'air du conducteur de chaleur. L'augmentation de la surface de contact entre le corps chauffant et le conducteur de chaleur améliore l'efficacité de transfert de chaleur entre le corps chauffant et le conducteur de chaleur. Le ménagement de la pluralité de structures de pores dans le conducteur de chaleur forme une pluralité de canaux d'écoulement d'air ayant des formes irrégulières, de façon à augmenter le débit d'air et à étendre des chemins d'écoulement d'air, ce qui permet de prolonger le temps de chauffage, et d'obtenir les effets d'amélioration de l'efficacité d'échange de chaleur et de réduction de la consommation d'énergie.
