The metal plate body of the bottom plate of the computer casing has a receiving groove in the center of the top surface of the heat dissipating plate. A A plurality of radially extending extending grooves are arranged around the receiving groove, and the I-thermal heat conductor has a corresponding arrangement. a hollow body in the accommodating groove, wherein the periphery of the body has a plurality of heat dissipating pipes respectively disposed in the extending grooves, and one end of each of the heat dissipating pipes is closed, and the other end is connected with the body, and the heat conducting body is filled with a predetermined amount of liquid refrigerant . The design of the prior art solution of the present invention mainly transmits the high temperature generated by the operation of the central processing unit of the notebook computer to the body of the heat conductor, so that the refrigerant therein is heated and vaporized and then rapidly diffused and transmitted through the surrounding heat pipes. A large area of the heat dissipation plate emits a temperature drop, and the gaseous refrigerant is cooled into a liquid state and can be returned to the body of the heat conductor for heat absorption. Thus, the heat transfer efficiency of the present invention is rapidly diffused by the gaseous refrigerant, so that the heat sink has Excellent fast cooling performance. [Embodiment] For a specific embodiment of the heat sink of the notebook computer of the present invention, please refer to the first and second figures of the I334525. The heat sink mainly includes a heat sink (10) and a heat conductor (20). The heat dissipating plate (10) is a heat-conducting metal plate body which can be installed on the bottom of the body of the notebook computer. The receiving plate (11) is disposed at the center of the top surface of the heat dissipating plate (10), and the self-receiving groove (1 1) There are several extending grooves (i 2 ) extending radially in the periphery, and an array of holes (14) can be arranged on the top of the heat dissipation plate (1 〇) to provide circuit board assembly. The heat conductor (20) has a metal hollow body (21) correspondingly disposed in the accommodating groove. The periphery of the body (21) has a plurality of correspondingly disposed in the extending groove (12). The heat pipe (2 2 ), the end of each heat pipe (22) is connected to the body (21), and the other end is a closed end, so that the heat conductor (2 ◦) internally forms a closed space, and the heat conductor (2 〇) interior A predetermined amount of liquid refrigerant (3 Torr) is charged after evacuation. In the foregoing, the body (21) in the middle of the heat conductor (20) is slightly lower than the heat pipe (2 2), and the inner section of the heat pipe (2 2 ) connected to the body (2 1 ) is slightly inclined downward. 'The bottom edge of the outer section of the heat pipe (2 2 ) is slightly higher than the top surface of the body (2 1 ), so that the liquid refrigerant concentrates inside the body (2 1 ). In the foregoing, the depth of the receiving groove (1 1 ) of the heat dissipation plate (1 〇) is greater than the height of the body ( 2 1 ) of the heat conductor (20), and the depth of the extending groove (12) around the receiving groove (1 1) is approximately equivalent. The heat pipe (22) has a diameter of a heat pipe (22), whereby the body (21) of the heat conductor (2) is placed in the receiving groove (1 1 ) of the heat sink (10) to dissipate heat. The tube (2 2) is placed in the extending groove (1 2) of the heat dissipating plate (1 〇), and the body (21) and the heat dissipating tube (22) of the heat conduction 1334525 body (20) are respectively separated from the heat dissipating plate (1 〇) A thermal conductive paste (13) is disposed between the groove of the receiving groove (11) and the extending groove (12) for enhancing the thermal conductivity between each other. When the heat dissipating device of the present invention is applied to a notebook computer, it is installed at the bottom of the computer casing as a bottom plate, as shown in the third and the figure, and is received by the body (2 1 ) in the middle of the heat conductor (2 〇). A central processing unit (4〇) attached to the computer 'The central processing unit (40) and the top surface of the heat conductor (2〇) body (2 1 ) may be provided with a thermal paste (丄3) to increase the mutual Thermal conductivity. After the computer is started, the high temperature generated by the central processing unit (4 〇) is transferred to the body of the thermal conductor (20) (and then the body (2 1 )) The refrigerant (3 〇) absorbs heat and evaporates into a gaseous state. The heat medium (2 Q ) is vacuumed and then filled with refrigerant. Therefore, after the refrigerant is vaporized, the gas that has been heated and then expanded is rapidly rushed to the surrounding area. In the heat pipe (22), the heat pipes (22) are further transmitted to the heat sinks ("〇"), and the heat is dissipated by expanding the heat dissipating surface area. The fan inside the notebook case (not shown) can further utilize the airflow to help the heat efficiency of the gas, and the gaseous refrigerant (30) that flows into the heat pipe (2 2 ) is cooled by the heat. Condensed into a liquid state and then flows back to the body (2 internal heat absorption, dispersion heat dissipation cycle. As can be understood from the above description, the heat sink of the present invention can transfer the heat generated by the central processing unit of the notebook computer to the heat conductor. Heat absorption by refrigerant After that, it is radiated to the heat dissipating plate through the number of heat dissipating tubes to disperse 1334525. Since the inside of the heat conductor is vacuumed and then filled with the refrigerant, the diffusion rate of the refrigerant in the heat dissipating tube is extremely fast, thereby making it hot in the heat ^ The efficiency of the lead can be effectively and quickly improved, and thus it has better heat dissipation performance than the combination of the conventional heat sink and the fan. Therefore, the present invention has innovative technical features and obvious advancement, so the present invention conforms to the patent requirements of the invention.
