Description
- (a) Field of the Invention
- The present invention relates to a heat sink fin and a heat sink device, and more particularly to a heat sink fin having an extension portion which is integrally formed with a lower end of the heat sink fin. The extension portion is folded to form a compressed block. The bottom of the compressed block is formed with at least one an engaging recess by stamping. The compressed blocks of a plurality of heat sink fins are connected with each other to form a block member as a base to couple a heat conduction pipe so as to constitute the heat sink device having the heat conduction pipe.
- (b) Description of the Prior Art
- A conventional heat sink device having a heat conduction pipe comprises a heat sink module, a metallic base and at least one heat conduction pipe. The heat sink module is composed of a plurality of heat sink fins which are connected one by one and coupled to the metallic base. The metallic base is a solid block. The heat conduction pipe is inserted into or coupled to the bottom of the metallic base. The base or the heat conduction pipe is attached to a heat source, such as a CPU or a memory or other electronic components, so that the heat can be conducted to the heat sink module through the heat conduction pipe and the base to enhance the heat dissipation efficiency.
- It is necessary to use solder paste for soldering the heat sink module, the base and the heat conduction pipe of the conventional heat sink device. Besides, the components are made by different metallic materials, so they must be electroplated before soldering. This complicates the processing and increases the cost. It is inconvenient to assemble the conventional heat sink device and it is not environment-friendly. The base of the heat sink device is solid, which is heavy and large in size and uses more metallic material to increase the manufacture cost. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
- The primary object of the present invention is to provide a heat sink fin and a heat sink device. The heat sink device comprises a heat sink module which is composed by a plurality of heat sink fins and at least one heat conduction pipe. The heat sink fin has an extension portion which is integrally formed with a lower end of the heat sink fin. The extension portion is folded or curled to form a semi-finished compressed block. The semi-finished compressed block has a bottom formed with at least one an engaging recess by stamping to constitute a compressed block. The compressed blocks of the heat sink fins are connected with each other to form a block member as a base. The engaging recesses of the heat sink fins are to form an engaging passage for engagement of the heat conduction pipe to constitute the heat sink device having the heat conduction pipe. The block member formed by the compressed blocks of the extension portions of the heat sink fins is to replace the conventional solid metallic base so as to simplify the configuration of the heat sink device without welding. The present invention can save the material, lower the cost and ensure the connection of the heat sink module and the heat conduction pipe. The heat generated by the electronic component can be immediately dissipated through the heat conduction pipe and the heat sink fins. The present invention provides a better heat dissipation efficiency.
- Another object of the present invention is to provide a heat sink fin and a heat sink device, wherein the heat sink fin can be in any shape and the length of the extension portion of the heat sink fin can be changed as desired.
- A further object of the present invention is to provide a heat sink fin and a heat sink device, wherein the extension portion of the heat sink fin is folded up in sequence to form the compressed block, or the extension portion is folded face-to-face more than once to form the compressed block, or the extension portion is curled to form the compressed block.
- A further object of the present invention is to provide a heat sink fin and a heat sink device, wherein the bottom of the compressed block of the heat sink fin has a support rib formed between two adjacent engaging recesses. The support rib has a height equal to the depth of the engaging recesses, so that there is an interval between two adjacent heat conduction pipes after assembled.
- A further object of the present invention is to provide a heat sink fin and a heat sink device, wherein the bottom of the compressed block of the heat sink fin has a support rib formed between two adjacent engaging recesses. The support rib has a height smaller than the depth of the engaging recesses to form a height difference between the support rib and the engaging recess. There is no interval between two adjacent heat conduction pipes after assembled.
- A further object of the present invention is to provide a heat sink fin and a heat sink device, wherein the compressed block of the heat sink fin is further formed with a connecting portion by stamping, so that the adjacent heat sink fins can be connected by the connecting portion to enhance the connection of the heat sink fins.
- A further object of the present invention is to provide a heat sink fin and a heat sink device, wherein the compressed block of the heat sink fin is further formed with a rivet hole by stamping for insertion of a rivet to firm the configuration of the block member.
- A further object of the present invention is to provide a heat sink fin and a heat sink device, wherein the heat sink module further comprises a pair of retaining blocks at two sides of the block member. Each retaining block is riveted with a threaded post to be coupled to a circuit board.
