Description of the invention: [Technical field to which the invention pertains] The present invention relates to a heat dissipation module, and more particularly to a heat dissipation module for dissipating heat from a heating element. [Prior Art] As the power of electronic components such as a central processing unit (CPU) continues to increase, the problem of heat dissipation has received more and more attention, especially in computers. In order to efficiently remove the heat generated by the system in a limited space, a finned heat sink or a heat pipe heat sink is generally placed on the electronic component to dissipate heat from the electronic component. In order to quickly transfer the heat generated by the electronic component to the heat sink, a heat collecting block is generally disposed between the heat sink and the electronic component, and the heat collecting block is made of a highly thermally conductive material such as copper, and the high thermal conductivity is utilized rapidly. The heat generated by the electronic components is evenly transferred to the heat pipes. The contact between the heat collecting block and the electronic component directly affects the speed of heat dissipation of the electronic component. Since the electronic component has a small volume, and the heat collecting block forms a surface contact between the flat structure and the electronic component, the contact area between the heat collecting block and the electronic component is basically determined by the surface area of the electronic component, and thus the contact The area is limited, which in turn affects its heat dissipation performance. Therefore, how to improve the structure of the heat collecting block and increase the contact area with the electronic component, thereby improving the heat dissipation performance, has become an urgent problem for designers. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a heat dissipation module that improves the contact area with a heat-generating electronic component. The heat dissipation module is used for dissipating heat from the heat-generating electronic component, including the heat collecting block, and the heat-receiving block has an upper surface and a surface opposite thereto, and the heat pipe-end and the Korean film are more than The other end is thermally connected to the surface, and the upper surface of the heat collecting block is provided with a groove, and the component receives the concave. The heat medium is used to dissipate heat from the heat-generating electronic components, including the heat collecting block, the base, the heat pipe and the fins, and the heat collecting block is disposed on the base, and the heat pipe is connected to the heat collecting block and the fin Between the groups, the surface of the heat collecting block forms a groove, and the groove has a bottom surface and a plurality of side surfaces, wherein the groove receives the heating electronic component therein, and the bottom surface and the side surface of the groove cover the heat The outer surface of the electronic component. Compared with the prior art, the groove on the heat collecting block can be in solid contact with the heat generating electron element, thereby increasing the contact area therebetween and reducing the thermal resistance therebetween, thereby improving the heat conduction efficiency of the entire heat dissipation module. [Embodiment] Referring to FIG. 1 to FIG. 3 simultaneously, the heat dissipation module includes a base 1 〇, a \ 4 \\\ tube 30, a fin set 9 〇, and a heat collecting block 50. A receiving groove 14 is disposed at a substantially central position of the base 10 for receiving the heat collecting block 50. A mounting hole 16 is formed around the accommodating groove 14 for accommodating the spring screw 40' to lock the base to the main board (not shown). A curved groove 12 is bent on the bottom surface of the base 10 for accommodating the heat pipe 3〇. The accommodating groove 14 of the base 10 communicates with the curved groove 12, so that the heat pipe 30 placed in the curved groove 12 can be directly connected to the heat collecting block placed in the accommodating groove 14. The fin set 90 is formed by a plurality of fin fins 92 arranged in parallel, and a phase 94 is formed between the phases 7 200816908 " for forced airflow (wind direction as indicated by the arrow in Fig. 3). The bottom edge of each of the fins 92 forms a square notch %, which is integrally formed to form a D-receiving space. The heat pipe 30 includes an evaporation end 31 disposed in the 3U^12 and a condensation end extending from the evaporation end 31. The condensation end is also formed in a west shape to correspond to the curved groove 12, and the cold mushroom 32 is accommodated in each of the (10) 92. The accommodating space formed is connected to the fin group 9 at a thermal speed. The heat pipe 3〇, and the contact area of the heat collecting block 5G and the fin group 9G. ',,, ' to increase the square 2 = medium 1 = heat block: full: structure diagram. The heat collecting block 50 50 is placed in the accommodating groove 14 and has a lower surface. The upper surface 54 of the heat collecting block, the lower surface 52 and the heat pipe 3 and the lower surface 52 are opposite to each other. The lower surface 52 and the heat pipe 30 are also filled and suspended in the heat collecting block to make the heat collecting block 50 and the heat pipe 3G contact. For the tightness, the interface material 2〇' is provided with a recess 5/, a small thermal resistance between the upper surface 54 of the heat collecting block 50. The heat-generating electronic component 80, such as the hard recess 56 at the center of the computer, has a side surface 57 and a bottom plate 57 (Fig. 5). The groove is chamfered in a circle. The side surfaces 57 and the bottom surface 58 are suspended: the bottom surface 58 between the two side surfaces 57 encloses a space of a substantially rectangular growth body, and the height of the side surface 57 and the side surface 57 is substantially determined by the size 2 of the heat generating electron element only surface 58 and The groove 56 can be sufficiently accommodating the surface area and height of the heat generating surface. Usually, the heat generating electronic component 8A and the inner surface 80 are also filled with a layer of thermal interface material 70, and the contacts of the groove 56 are contacted. When assembled, 'the evaporation end of the heat pipe 30 = the transfer of heat. Placed in the curved shape 8 200816908 of the base 10, the condensation end 32 is connected to the fin set 3〇. The heat collecting block 5 is placed in the cavity 14 of the base 10, and the heat-generating electronic component 80 is received in the recess 56 of the upper surface 54. The evaporation end 31 of the heat pipe 3 is disposed in the receiving groove ★ 14 The portion is thermally coupled to the lower surface 52 of the heat collecting block 50 via a thermal interface material 2, which reduces the contact thermal resistance. A thermal interface material 20a is further disposed on the top surface of the base 1 at a position corresponding to the end of the evaporation end 31 of the heat pipe 30 for use with another heat-generating electronic component (not shown) such as a south bridge chipset of the computer, the north bridge. The wafer set is in contact with it to dissipate heat. Finally, the base 1b can be locked to the main board by the mounting holes 16 by the spring screws 40. The heat generated by the heat-generating electronic component 80 is transferred to the heat pipe 30 through the heat collecting block 5, and then transferred to the fin group 9 through the heat pipe 30, and the fin group 90 is blown by the forced air flow, so that the heat-generating electronic component 8 is generated. The heat is discharged in time to ensure that the heat-generating electronic component 8 is operated at a normal temperature. Moreover, since the heat generating electronic component 80 is buried in the heat collecting block 50 due to the structure of the recess 56 formed on the heat collecting block 50, not only the bottom surface 58 of the recess 56 is in contact with the heat generating electronic component 80, but also the respective side surfaces 57 are also associated with the heat generating electrons. The element 8 is in contact with each other to form a three-dimensional, two-dimensional coating contact mode, which increases the contact area with the heat-generating electronic component 80, thereby enabling the heat generation and the heat generation to be transmitted more quickly, so that the entire heat dissipation module The heat dissipation performance has been improved.
