Combination method of heat dissipation aluminum box and heat sink

The present invention relates to a method for combining a heat-dissipating aluminum box and a heat-dissipating member, and more particularly to a method for combining a stamping and spot-welding process into a stamping and a combined process to reduce the number of processes and reduce the manufacturing cost of the heat-dissipating aluminum case and the heat sink. .

Generally, a portable electronic device, such as but not limited to a notebook computer, has a power converter for converting the streaming power source into a DC power source for use by the portable electronic device. The electronic components in the power converter generate heat. For heat dissipation, a heat-dissipating aluminum box is usually placed under the printed circuit board inside the power converter to assist in heat dissipation.

Referring to FIG. 1a to FIG. 1b, FIG. 1a is a schematic diagram of a conventional aluminum tape of a power converter; FIG. 1b is a schematic view of a patch tape of a conventional power converter. As shown in the figure, the heat-dissipating aluminum case of the conventional power converter respectively places an aluminum box tape 100 in a first mold (not shown), and the aluminum box tape 100 has a plurality of aluminum boxes 101 thereon. A patch tape 110 is placed in a second mold (not shown). The patch tape 110 has a plurality of patches 111, and the aluminum cassette tape 100 is punched by a punching machine (not shown). After the patch tape 110 is punched into half of the finished product, the patch 111 is spot-welded to the bottom of the aluminum case 101, and the heat generated by the aluminum case 101 is led out by the patch 111.

However, the above-mentioned conventional technology requires the aluminum box tape 100 and the patch tape 110 respectively. A set of molds is stamped and formed, and after the molding, the patch 111 is spot-welded to the bottom of the aluminum case 101. If there are four solder joints, spot welding is required four times, which will cost a lot. Manpower, increasing manufacturing costs, is a flaw in the United States.

In view of the shortcomings of the above-mentioned combination method of the heat dissipating aluminum case and the heat dissipating member, the present invention provides a method for combining the heat dissipating aluminum case and the heat dissipating member to improve the above disadvantages.

One of the objectives of the present invention is to provide a method for combining a heat-dissipating aluminum case and a heat-dissipating member, which can simplify the two processes of stamping and spot-welding into a stamping and simultaneous bonding process to reduce the number of processes and reduce the manufacturing cost.

One of the objectives of the present invention is to provide a method for combining a heat-dissipating aluminum case and a heat-dissipating member, which simultaneously places a metal box tape and a patch tape in a set of molds, and then placed in a punching machine for stamping and simultaneous bonding, thereby reducing the mold The number and reduction in manufacturing costs.

For the above purpose, a method for combining a heat dissipating aluminum case and a heat dissipating member of the present invention comprises the steps of: placing a metal box tape on a first stage of a punching machine; On the second stage of one of the punching machines; and punching the strip of the strip and the strip of the metal box with a die of the punching machine, so that a patch on the strip of the patch is bonded to the metal box Bring it on one of the metal boxes.

The detailed description of the drawings and the preferred embodiments are set forth in the accompanying drawings.

Referring to FIG. 2 to FIG. 4 , FIG. 2 is a schematic flow chart of a method for combining a heat dissipating aluminum case and a heat dissipating member according to a preferred embodiment of the present invention; FIG. 3 is a view showing a metal case tape according to a preferred embodiment of the present invention; And the schematic view of the upper side of the finished product manufactured by the method according to a preferred embodiment of the present invention.

As shown in the figure, a method for combining a heat dissipating aluminum case and a heat dissipating member according to a preferred embodiment of the present invention includes the following steps: placing a metal box tape 10 on a first stage 50 of a punching machine (step 1) a patch tape 20 is placed on the second stage 60 of the press (step 2); and the patch tape 20 and the metal box tape 10 are stamped by one of the punches, A patch 21 on the patch tape 20 is bonded to a metal case 11 on the metal tape strip 10 (step 3).
