Description of the Invention: [Technical Field] The present invention relates to a heat dissipation module, and more particularly to a heat dissipation module suitable for a portable electronic product such as a notebook computer. [Prior Art] § Shovel, with the rapid development of the computer industry, the heat generated by the heat-generating electronic components such as micro-processing wafers is increasing. In order to effectively superimpose these excess heat, the conventional method is on the surface of the heat-generating electronic components. A heat sink is attached to 'enforce the heat generated by the heat-generating electronic components with the aid of the heat pipe and the heat-dissipating fan. In order to fix the above heat sink, heat pipe and cooling fan, the book requires additional fixing components such as fasteners, and many components are required, which inevitably requires an increase in the space occupied by the heat dissipation module in the casing. However, portable electronic products such as notebook computers in the market generally tend to be light, thin, short, and small, so as to be convenient to carry and use, and conventional heat dissipation modules are obviously difficult to meet such requirements.

The heat sink 30 includes an upper contact surface 32 and a lower contact surface, for example, the contact surface 32 is for contact with a heat-generating electronic component (not shown), and the lower contact surface 34 is used. In contact with the casing 2〇. The lower contact surface 34 is provided with a receiving 曰 36. The four corners of the heat collecting seat 3 are outwardly projecting with four fixing arms. The cooling fan 40 includes an air outlet 42, and the cooling fan milk is connected to the heat collecting seat 30 and is located on one side of the heat collecting seat. The heat pipe 5 is substantially L-shaped and has an evaporation end 52 and a condensation end 54. Referring to FIG. 1 and FIG. 2, the heat sink 10 is located near the side of the casing 2, and each fixed arm 38 of the heat collecting block 30 is fixed to the casing 20 by a screw 60 and The lower surface of the heat collecting block 30 is in contact with the casing 20, and the heat dissipating fan 40 is positioned in the casing 20 adjacent to the heat sink 10, and the air outlet 42 of the heat dissipating fan 40 is radiating The device 10 is configured to perform forced heat dissipation on the heat sink 10. The evaporation end 52 of the heat pipe 5 is received in the receiving groove 36 of the heat collecting block 30. The condensation end 54 of the heat pipe 5 is flat on the upper surface of the heat sink 10. Of course, the condensation end 54 7 1289428 can also be combined with the heat sink 10 by means of the heat dissipation fins of the heat sink 10. In the manufacturing and assembly process, the heat sink 10 is directly bonded to the casing 20 by means of a die cast molding. During molding, the formed heat sink 10 is mounted into a die-casting mold, and after filling the mold, a liquid magnesium alloy (for example, a magnesium alloy) is injected to bring the bottom of the heat sink 10 into contact with the liquid magnesium alloy. The casing 20 formed by the alloy is joined to the bottom of the heat sink 1 so that the heat sink 10 is integrally embedded in the casing 2 and tightly coupled with the machine 20. By tungsten embedding, the heat sink and the machine 20 have the advantages of simple process, tight combination, low thermal resistance and no need to use components such as clips for fixing. In order to reduce the thermal contact resistance between the heat pipe 50 and the heat sink 1, a heat conductive paste may be applied between the heat pipe 5's and the heat sink 10 or the heat pipe 5'' may be welded to the heat sink 10 by solder paste. Similarly, in order to reduce the contact thermal resistance between the collector block 3 and the casing 2, a thermal paste may be applied between the collector block 30 and the casing 20. When the thermal module 100 is used, the heat collecting block 3 absorbing the heat generated by the heat generating electronic component and transmitting it to the casing 2 and the heat pipe 5〇 at the same time. The casing 20 directly dissipates heat, and the heat pipe 5 turns heat from the evaporation end 52 to the condensation end 54, and the condensation end 54 transfers heat to the radiator 1 and is further transmitted to the casing through the radiator 10. . Since the surface area of the casing 2 is large, it is advantageous for the heat dissipation module 100 to dissipate heat rapidly. At the same time, the airflow generated by the cooling fan 40 forcibly dissipates heat from the heat sink 10, and directly radiates the heat I transmitted to the heat sink 10 to the outside of the casing 20, which is beneficial to improving the overall heat dissipation efficiency of the heat dissipation module 100. 1289428

As can be seen from the above description, since the heat collecting block 3〇 and the heat sink (10) are in contact with the casing 20, the heat generated by the heat generating electronic component is transmitted to the casing 20, and at the same time, the heat radiating fan 4 The heat is directly dissipated and the outside of the housing 20 makes the heat dissipation module 100 more efficient in heat dissipation.
