2364179 TITLE: AN IMPROVED STRUCTURE FOR A HEAT DISSIPATION DEVICE

BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention relates to a heat dissipation device, and in particular, to an improved structure for a heat dissipation device which is mounted close to the CPU of a PC to dissipate heat energy produced therefrom.

(b) Description of the Prior Art

When a PC is in operation, due to heat energy produced by the PC, the temperature within the computer increases If the CPU is overheated, the entire computer will not function normally Therefore, heat dissipation device is installed to the CPU to dissipate heat Referring to Fig 1, there is shown a conventional heat dissipation device 1 comprising a base seat 11, and a heat conductive tube 13, and the device 1 is used to dissipate heat A fan 15 is mounted to withdraw hot air, but if the heat energy cannot be collected at a specific location the fan 15 cannot be effectively performed its function In the conventional structure, the heat energy at the base seat 11 is collected but the heat conductive tube 13 is mounted onto the base seat 11 with a plastic body 12 The heat conduction of plastic body 12 is poor, and the plastic body 12 may be dislocated after a period of time As a result, the heat energy of the base seat 11 cannot be effectively transmitted to the heat conductive tube 13 Due to collection of excessive heat within the computer, the CPU may be malfunctioned or damaged.

Referring to Fig 2, there is shown a CPU 9 being slotted onto a mother board 7 The heat dissipation device 14 has a heat dissipation fin 16 having the size of the CPU 9 The top of the fin 16 is mounted with a fan 15.

However, such heat dissipation device 14 does not have a heat collection system and the heat energy cannot be collected As a result, the efficiency of heat dissipation is poor, and the heat energy will remain at the fin 16 and flow back to the CPU 9 The excessive heat at the CPU 9 will damage the CPU 9 and cause a malfunction to the CPU 9.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings Specific language will be used to describe same It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

Referring to Figs 3 and 4, there is shown an improved structure for a heat dissipation device comprising a heat-conductive heat collection seat 2, a finned heat dissipation sleeve 3, a hood 4, a fan 5, and a plurality of screws 6.

The heat-conductive heat collection seat 2 comprises a one-piece heatconductive tube 22 and a base seat 21 having a plurality of fixing holes 211.

The plurality of screws 6 are used to secure the heat dissipation device of the present invention onto the top of the CPU of a computer The center of the finned heat dissipation sleeve 3 is provided with an elongated hollow slot 32 such that the heat-conductive tube 22 can be inserted within the slot 32 as a shaft center of the dissipation device A plurality of heat dissipation plates 31 are provided to the sleeve 32 in such a way that the dissipation plates 31 are extended outward The external shape of the finned heat dissipation sleeve 3 is substantially a square shape, and a fan-like gap 33 is formed between a pair of individual heat dissipation plate 31 The hood 4 being substantially a box- like structure comprises four blocking plates 43 mounted perpendicularly to each other along their side edges The top of the four blocking plates 43 is covered with a top blocking plate 44 with a center cavity 41 forming into a square-shaped body The center cavity slot 41 is formed within the square- shaped body, and the capacity of the cavity slot 4 is slightly larger than the size of the finned heat dissipation sleeve 3, such that the hood 4 can be mounted onto the top of the finned heat dissipation sleeve 3 The surroundings of the top blocking plate 44 are provided with a plurality of bottom screw holes 42 such that the fan 5 can be mounted onto the top screw holes 51 provided on the edge of fan 15 by screws 6 and the fan is secured at the bottom screw holes 42 of the hood 4 The center of the top blocking plate 44 is provided with a circular opening allowing the air to be withdrawn by the fan 5.

Referring to Fig 5, a plurality of screws 6 are used to mount at the fixing holes 211 of the base seat 21 and the heat dissipation device is fixed to the top of the CPU 8 located on the mother board 7.

Referring to Fig 6, the heat dissipation device of the present invention can be applied to another type of CPU 9 which is inserted into slots on a mother board 7 A plurality of screws 6 pass through a plurality of fixing holes 21 on the base plate 21 and then the heat dissipation device of the present invention is mounted to the CPU 9.

Referring to Figs 7,8 and 9, the arrow indicates the directions of heat flow.

As shown in Fig 7, the heat from the CPU 8 is transmitted via the base seat 21 of the heat-conductive heat collection seat 2 and collected at the heat conductive tube 22 The heat-conductive heat collection seat 2 comprises a one-piece heat dissipation tube 22 and the base seat 21 such that the heat energy is effectively collected at the heat conductive tube 22.

Referring to Fig 8, the heat energy of the heat-conductive tube 22 is dissipated out via the heat dissipation plates 31, and the remaining heat energy which cannot be self-dissipated is collected at the fan-like gaps 33 formed between two individual heat dissipation plates 31.

As shown in Fig 9, the rest of the heat energy, and the heat energy collected at the gap 33 are gathered within the hood 4 The convection current by the fan 5 draws away the heat Thus, the CPU 8 at the mother board 7 will not be overheated but can operate normally to provide effective working condition.
