Abstract
La présente invention concerne un dispositif de dissipation de chaleur qui comprend un ventilateur thermoconducteur. Le ventilateur thermoconducteur comprend une base, un boîtier et des pales de ventilateur. Le boîtier est enserré par une surface supérieure et quatre surfaces latérales et est relié de manière fixe à la base pour former une cavité. Les pales de ventilateur sont installées rotatives dans la cavité. Une entrée d'air de ventilateur est formée au niveau de la surface supérieure du boîtier faisant face à la base. Une sortie d'air de ventilateur est formée au niveau de l'une des deux surfaces latérales du boîtier. La base est constituée d'un matériau thermoconducteur. Selon l'invention, la chaleur générée par une source de chaleur est directement guidée vers un ventilateur, de sorte que l'air produit par le ventilateur transfère la chaleur. Étant donné que l'invention utilise une conduction thermique directe, une zone d'un élément de dissipation de chaleur peut être réduite, ce qui permet d'obtenir un dispositif de dissipation de chaleur ayant une structure compacte et une petite masse. De plus, étant donné que l'air est directement dirigé vers une source de chaleur, un trajet d'air est plus simple, ce qui permet d'empêcher une conception de trajet d'air complexe, d'empêcher efficacement l'accumulation de chaleur et d'abaisser significativement une température.
