Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a heat dissipator as an accessory of a notebook computer, and more particularly, to an external heat dissipator that is inserted into an expansion slot of the notebook computer and effectively dissipates heat generated by the computer.

[0002]

[Prior art]

 In general, in a computer, the higher the processing speed of the CPU, the higher the operating temperature (heat generation temperature) of the CPU. Therefore, regardless of the type of the computer, an independent radiator is installed in the central processing unit (CPU) of the computer host. ) Is necessary. However, other elements of the computer host other than the CPU generate heat during operation. In a desktop personal computer, heat generated by each element of the computer host is naturally dissipated in a large internal space. However, in a portable notebook computer, the heat from the notebook computer is not sufficiently dissipated to a small internal space because of the dense arrangement of these elements. To ensure that computers operate at the right temperature, it is necessary to develop radiators that effectively dissipate the heat generated by notebook computers without taking up significant internal space. It is.

[Embodiment of the invention]

 Referring to FIG. 1, a heat dissipation accessory or external heatsink in accordance with the present invention includes a cooling module 200 that is inserted into an expansion slot 11 pre-formed in a notebook computer 10. The cooler module 200 solves the problem of heat dissipation of the components located within the notebook computer 10 while not changing the appearance and increasing the volume of the notebook computer 10.

Referring to FIG. 2, the cooling module 200 includes a shallow flat flat body 20, a cover 30, and an air duct 40 assembled to the cover 30. The flat body 20 has at one end a connector 21 that is electrically connected to a signal socket 12 (see FIG. 4) disposed in an expansion slot 11 of the notebook computer 10. Therefore, the cooling module 200 can use the power from the notebook computer 10. The periphery of the cooling module 200 is formed by the outer peripheral wall 22 except for the connector 21. The outer peripheral wall 22 has a chamber 23 in which a fan 25 is disposed and an air passage 24 communicated with the chamber 23 inside the outer peripheral wall 22. The plurality of boards 26 are spaced apart in the horizontal direction (width direction) between the chamber 23 and the air passage 24 so as to direct air from the chamber 23 to one end of the air passage 24 in the vertical direction (longitudinal direction). It is arranged so that it extends. As shown in FIG. 3, the air deflector 27 has an inclined curved surface 270 that obliquely changes the direction of the horizontal air flow upward. The flat body 20 further includes an outer flange 201 for holding the cover 30, and a pair of opposing recesses 202 provided inside the flange 201 so as to engage with the air duct 40.

Still referring to FIG. 2, the cover 30 has a shape that matches the flat body 20 and is held by the outer flange 201 of the flat body 20. The hole 31 formed in the cover 30 is aligned with the chamber 23 so as to exhaust air from the chamber 23 of the flat body 20. A pair of cutouts 34 formed on both sides of the cover 30 are aligned with the opposite recesses 202 of the flat body 20. The cover 30 has an inclined portion 32 corresponding to the air deflector 27. A plurality of openings 33 are formed in the inclined portion 32 of the cover 30, and the openings 33 are aligned with the inclined curved surface 270 of the air deflector 27 so as to direct air from the flat body 20 to the outside.

The air duct 40 is attached to an end of the cover 30. The air duct 40 has a plurality of slits 41 extending from its ends at locations corresponding to the holes 31 of the cover 30, whereby cold air is introduced into the chamber 23 through the holes 31. The air duct 40 has a pair of ribs 42 on both sides corresponding to the notches 34 of the cover 30. Ribs 42 are received in a pair of recesses in flat body 20. The flat body 20 has a shallow depression or recess 29 (see FIG. 4). Substrate 28 is received in a shallow slot or recess 29 surrounding one or more wires (not shown) coupled to flat body 20 to supply power to fan 25.

The cooling module 200 is inserted into the expansion slot 11 of the notebook computer 10 and concealed (see FIG. 5). Therefore, the volume of the computer 10 does not increase. The electric power of the fan 25 is provided by the connector 21 connected to the signal socket 12. When the notebook computer 10 is operated, the connector 21 obtains electric power from the signal socket 12 and supplies it to the fan 25, and the fan 25 introduces cool air into the chamber 23 through the slit 41 of the air duct 40. The cool air flow introduced by the fan 25 is directed to the air passage 24 through the space between the boards 26. When the cool air flow reaches the air deflector 27, the cool air flow is guided by the inclined curved surface 27 and sent out from the opening 33 of the cover 30 into the computer 10. Since the slit 41 is arranged near the end of the cover 30, only the cool air from the outside is introduced, and the heated air from the computer 10 is not introduced. Due to the nature of the openings 33, the cool airflow is concentrated and strengthened. Therefore, an excellent heat dissipation effect is obtained.

The heat dissipation of the notebook computer 10 in the above embodiment is achieved by a method in which the fan 25 introduces cool air from outside the computer 10 and sends it into the computer 10. In addition to the first embodiment, the heat dissipation of the notebook computer 10 can also be achieved by forcibly discharging the heated air generated by the computer 10 to the outside of the computer 10 by the fan 25. it can.

FIG. 6 and FIG. 7 show an accessory or external heat sink according to a second embodiment of the present invention. The second embodiment has the same basic configuration as the first embodiment except that the structure is simplified by integrally disposing the air duct 40 at one end of the cover 30. Also, the lower surface of the flat body 20 is shaped to have a wire case (not shown) for receiving a plurality of wires without providing the substrate 28. In this way, the components of the external heatsink are reduced and the overall structure is simplified.

Although various features and advantages of the present invention have been set forth in the foregoing description, such description and description are for the purpose of example, and in particular, the arrangement, shape, and specifics of the components may be varied. Various changes can be made.
