Description

  The present invention relates to a heat sink module, and more particularly, to a heat sink module having an effect of reducing heat conduction resistance, effectively improving heat conduction efficiency, and effectively reducing cost.

With the progress of semiconductor technology, the volume of integrated circuits is gradually reduced, and in order to process more data in the integrated circuit, the integrated circuit of the same volume is equipped with several times more devices than the conventional one, As the number of devices in an integrated circuit increases, the thermal energy generated during operation of these device materials also increases. For example, when the CPU operates at the maximum operating rate, the CPU generates a considerably high amount of heat, so If the amount of heat cannot be released, abnormalities or damage (burnout) of the electronic member is likely to occur. For this reason, the heat sink module of an integrated circuit has already become an important issue.

The existing heat sink module generally adopts a conduction method, and dissipates the amount of heat generated by the CPU. As shown in FIG. 1, the conventional heat sink module includes a base 10, a heat pipe 12, and a heat sink fin assembly 14. The base 10 is made of a copper material, and includes a first end face 101 and the first heat sink module. A second end surface 102 opposite to the one end surface is provided, and a through hole 103 is provided between the first end surface 101 and the second end surface, and one end of the heat pipe 12 is installed and fixed. The second end face 102 is bonded onto the heat generating member 16 (CPU, north south bridge chip, etc.), absorbs the amount of heat generated by the heat generating member 16, and transmits it to the heat pipe 12 in the through hole 103.

The heat pipe 12 includes a heat absorbing portion 121 and a heat radiating portion 123, and the heat absorbing portion 121 (that is, one end of the heat pipe 12) is accommodated in the through-hole 103 and joined to the heat absorbing portion 121. The base 10 is integrally coupled, and the heat radiating portion 123 is butt-joined with the heat sink fin assembly 14. Accordingly, when the heat generating member 16 generates heat, the second end face 102 of the base 10 conducts the received heat to the heat absorbing portion 121 in the through hole 103, and the heat absorbing portion 121 radiates the heat of the base 10. The heat sink fin assembly 14 connected on the portion 123 is conducted to dissipate heat to the outside, and a heat dissipating effect can be achieved.

  However, the conventional heat sink module can achieve the purpose of heat dissipation with respect to the heat generating member 16, but the effect is not remarkable, and the details are as described below. When the conventional heat sink module dissipates heat to the heat generating member 16, it is necessary to transmit the amount of heat through the base 10, so the heat amount of the heat generating member 16 passes through the base 10 and further to the heat pipe 12. Since it is transmitted to the heat sink fin assembly 14 above, the heat conduction path is long, and thermal resistance is generated in the process, so the overall thermal efficiency is not good and the overall heat dissipation effect is relatively poor.

Further, in manufacturing a conventional heat sink module, it is necessary to use a large amount of tin solder material and fix the heat pipe 12 on the base 10, which increases the manufacturing process time and cost. Furthermore, in order to reduce the overall cost, the contractor changed the copper base to an aluminum base, covered the aluminum base with electroplating, and then welded the base. Although the heat pipe is fixed to the aluminum base, the conventional method reduces the cost by changing the base material, but the heat absorption effect of the aluminum base is better than the heat absorption effect of the copper base. However, there is a problem that the overall heat sink effect is reduced.

As mentioned above, the prior art has the following drawbacks:
1.
The heat conduction efficiency is not good.
2.
Manufacturing process time increases and costs increase.
3.
The heat dissipation effect is not good.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is a place where improvement of research by those skilled in the art is desired.
