    BACKGROUND OF THE PRESENT INVENTION
  • 1. Field of Invention
  • The present invention relates to a radiator fin for conducting heat, and more particularly to a radiator fin which is used in the fields of chips, semiconductors, and other electric elements for cooling. Further, the present invention also includes a radiator fin component which comprises the radiator fins and a base.
  • 2. Description of Related Arts
  • The heat conducting methods of conventional heat elimination devices which are used in the fields of chips, semiconductors, and other electric elements for cooling are many, and the heat conductors are often made of aluminum by extrusion forming methods or joints composed of aluminum vanes and copper vanes, so the areas and strength of the conventional heat elimination devices for cooling are limited. On the other hand, the interfaces in contact with air are quite small, so the conventional heat elimination devices are high-priced, while the effect of heat elimination of the conventional heat elimination devices is not good.
  • When the heat elimination component which is composed of the conventional metal radiator fins and the base is used for cooling, the joint method between the metal radiator fins and the base is often a “pinching method,” i.e., the radiator fins are pushed into corresponding grooves in the base, and suitable pressure is exerted on both sides of the corresponding heat elimination component to fix the radiator in the base. However, the pinching method of the conventional component increases the possibility of radiator fins falling off from the base, and the small cooling interface between radiator fins and the base greatly decreases the cooling effect. Furthermore, the construction of the conventional heat elimination component is complicated and inconvenient to operate.
    • SUMMARY OF THE PRESENT INVENTION

  • The strengthen vanes are longitudinally or laterally provided between the two heat conducting vanes. The two heat conducting vanes are joined end-to-end and top-to-top by welding. Further, the two heat conducting vanes can be provided into closed bodies.
  • The heat conducting vanes and the strength vanes are in porous structure.
  • The two heat conducting vanes in the present invention, which are in porous structure, replace the conventional conducting vanes made of aluminum plates, and the heat conducting vanes of the present invention can bear high-pressure. Further, the two heat conducting vanes are face to face, allowing ventilation regions with multiple heat conducting paths, thereby providing a good cooling effect.
