Description
- This application is a divisional application of prior U.S. application Ser. No. 11/530,149, filed Sep. 8, 2006, which is now pending. The entirety of the prior application is incorporated by reference herein.
- (a) Field of the Invention
- The present invention relates to a cooler device and more particularly to the mounting arrangement of the metal base member and metal radiation fins of a cooler device, which greatly increases the contact surface area between the metal base member and the metal radiation fins and is environmentally friendly.
- (b) Description of the Prior Art
- Conventional heat sinks are commonly comprised of a base member and a plurality of radiation fins arranged in parallel on the metal base member. The base member and the radiation fins are generally extruded from aluminum or copper. Therefore, the base member of a conventional heat sink is called the aluminum base or copper base. Further, regular heat sinks include heat sinks with heat tubes and heat sinks without heat tube. In a heat sink without heat tube, the radiation fins are arranged in parallel and fastened to one another by respective hooked portions thereof. In a heat sink with heat tubes, heat tubes are fastened to the radiation fins to secure the radiation fins together. Further, a heat sink may be provided with an electric fan to enhance heat dissipation.
- Further, the radiation fins of a conventional heat sink are soldered to the base member with the application of a solder paste or bonding agent. Further, when fastening copper heat tubes to an aluminum base member, a nickel-plating procedure is necessary. The use of a solder paste or bonding agent or the application of a nickel-plating procedure greatly increases the manufacturing cost of the heat sink. Further, the application of a nickel-plating procedure is not environmentally friendly.
- There are heat sinks in which the base member is secondarily processed to provide parallel mounting grooves and then the base member is compacted to secure the radiation fins in place after insertion of the radiation fins into the mounting grooves. However, the secondary processing of the base member greatly increases the cost. Further, the limited contact surface area between the base member and the radiation fins does not allow quick transmission of heat energy from the base member to the radiation fins for quick dissipation.
- The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the cooler device comprises a metal base member, and a plurality of metal radiation fins mounted on the metal base member. The metal radiation fins each have at least one backwardly curved and crimped bottom mounting portion. The metal base member has a plurality of deep locating grooves, which receive the backwardly curved and crimped bottom mounting portions of the radiation fins; the metal base member is compressed to fixedly secure the backwardly curved and crimped bottom mounting portions of the radiation fins to the metal base member. Therefore, the radiation fins are quickly and easily affixed to the base member without electroplating or the use of solder paste or bonding means, i.e., the mounting procedure of the present invention is environmentally friendly.
- According to another aspect of the present invention, each radiation fin has a plurality of backwardly curved and crimped bottom mounting portions respectively fastened to the base member. Therefore, the thickness of the bottom side of each radiation fin is relatively increased, i.e., the contact surface area between the radiation fins and the base member is relatively increased for quick transmission of heat energy from the base member to the radiation fins.
- According to still another aspect of the present invention, the backwardly curved and crimped bottom mounting portions of said metal radiation fins can be made to show a U-shaped profile, a L-shaped profile, a triangular profile, an inverted T-shaped profile, or a scroll-shaped profile.
- According to still another aspect of the present invention, each radiation fin has the bottom side turned backwards and crimped, therefore the bottom mounting side of each radiation fin has a certain wall thickness, and the base member can be directly extruded from aluminum or copper to provide the matching locating grooves for the mounting of the backwardly curved and crimped mounting portions of the radiation fins quickly and efficiently without a secondary processing.
