Description of the Invention: The present invention relates to a hybrid heat sink, a method of manufacturing the same, and an electronic component incorporating the heat sink thereof, especially a type It has the heat pipe and the heat dissipation effect of increasing the heat dissipation area, which not only can effectively improve the heat dissipation performance of electronic components, but also has a modular effect and is easy to quantify the manufacturing technology. [Prior Art] With the advancement of technology, electronic products are constantly being introduced. Most of the electronic products 'because of the emphasis on thin and light' and processing speed, the relative computing or processing components are mainly electronic components made of semiconductors, which are small in size and fast-moving environment. It is easy to generate a lot of heat, such as the central processing unit, 'the motherboard with various electronic chips' or the light-emitting diodes made of stupid crystals, which will generate a lot soon after starting up. Heat, if it is not effectively dissipated to reduce the temperature, working in a high temperature environment will reduce the speed of its processing or calculation, and even cause damage, and the heat is generally excluded by conduction, convection and radiation. The method discharges heat to the surrounding environment and reduces the operating temperature of the electronic product to maintain the stability and reliability of the system operation. In order to dissipate the heat generated by the operation of electronic components or semiconductor electronic components, to increase or transfer the speed of the processing operation, and to avoid damage, the central processing unit or the light-emitting diode in the electronic components In the polar body, there will be a heat sink or a heat sink module. By means of the scatter, the efficiencies are the most common. The heat sink is a heat sink fin. The heat sink is a heat sink fixed to the surface of the electronic component. Material 3 1^558^2, Supplementary revision date: November 11th, 100th, in order to bring the hot material generated by the electronic components to the environment, the structure is mostly composed of the bottom plate and the piece of the substrate. When the components are in contact, the main side is soaked, the heat is quickly conducted and diffused, and the function of the Korean part is heat dissipation. The heat generated by the bottom plate is transmitted by the increase of the surface area, and the air is heated from the surface of the fin. Scattered to the surrounding environment. When the surface area of the fin is larger, the better the heat dissipation effect, the more the 70 pieces of electrons can achieve the desired performance, and the more energy-saving effect. In the application of computer heat sinks, the factors affecting the heat dissipating components are as follows: 丨. The influence of the process: including material factors, stress concentration, contact surfaces and cracks, etc., will affect the heat transfer effect; 2. Environment Factors: Due to excessive internal obstruction of the computer, it is not conducive to airflow and ventilation, resulting in poor heat dissipation and reduced heat sink effect. The heat sink is the most widely used heat sink process. The manufacturing method is to heat the heat to about 52G~54 (rc, let the weave __ mold under high pressure, make the heat sink with continuous parallel grooves After secondary processing, the initial embryo is cut and grooved to form a heat sink. The commonly used transformation material is _63, which has good thermal conductivity (about 16H8G W/mK) and processability, which is the most common application. Due to the low capital investment and low production cost, and the low technical cost and short development period, the heat sink is generally used on the table (4) brain and sputum which is not limited by space. , _ type heat sink is limited by the process method, its shape is simple, lack of change, it is difficult to adapt to the new product shutdown, domain _ (10) (four) slender ratio has its off (about < 15), in the finite air town difficult to scream high dispersion With the heat transfer efficiency, the heat dissipation effect is poor. The working frequency of the desktop computer has reached 3 or more. The Razaki (4) Lang has been subject to shrinkage. It is necessary to seek technical and material advances. 1355882 Supplementary amendment date: 100 years November One step breakthrough on the 11th. In addition, 'aluminum extruded heat dissipation Due to the low technology and low price, the profit margin is limited, and the profit is not easy to be transferred.

In recent years, researchers at home and abroad have done a lot of work, and most of them have not studied the actual vacuum pressure in the mold. In general, the cavity exhaust in the production is not sufficient, and the cavity pressure is generally higher than Pa. The effect of the vacuum die casting on reducing the gas content of the pound is not stable enough, and the vacuum system has the effect of diversion. And can do (four) and ==== two products' is commonly used on notebook computers subject to lang restrictions. The commonly used lining age gold is section 2, because of the good die-casting property, it is suitable for making thin scales. The implementation rate is poor (about 96 is now more than the use of Qingsaki as a die-casting material, ,, heat conduction The rate is up to 200 _, with good heat dissipation effect, but there are some problems as follows: AA1070 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Rate α < face / mK) 3. Die casting mold is easily corroded by aluminum liquid, mold life is too short 4. Formability is poor, not suitable for thin meat parts 5. The material is soft and prone to deformation. The main performance of the phantom guide alloy filling cavity can only be called "vacuum assisted die casting". Japan's die-casting industry has conducted long-term and in-depth research on vacuum lining, and first proposed the high-vacuum die-casting technology of cavity vacuum pressure < 5 kPa, which has further improved the performance of die-casting parts. A certain amount of research results have been published for the change of cavity vacuum pressure in the vacuum die casting process. There are two main types of high-vacuum pressure-pound technology; - a method jointly developed by MuHingarten and Vaw in Germany, and a supplementary amendment date: November 11, 100, the MFT method introduced by Alcan-BDW, Germany. The Vacural method is to directly connect the melting furnace through the riser tube and the injection chamber. When vacuuming, the metal aluminum liquid is first sucked into the injection chamber, and then the vacuum is continued to a predetermined degree of vacuum before being injection molded. The MFT (Minimum Fill Time) rule uses an ordinary die-casting machine. The process features a multi-washing and a large-area internal rinsing to ensure that the molten metal fills the cavity in a very short time. Since the Vacural method requires a dedicated die casting machine and the technology is patented, the die casting machine is expensive and costly. Relatively speaking, the MFT method uses a common die-casting machine, and the threshold of the equipment is low, and the wheel height is high, and the system has a good prospect. Shooting - the Vac_ Golve Box method developed by Yamaha Corporation of Japan, which is difficult to consider because it is considered that the ejector is not sealed at the core, the structure is to install the whole mold in a sealed hood and set several suction rafts to extract Sealing cover _ with air, interesting to the south vacuum in the cavity. In view of the many shortcomings of the existing conventional heat dissipation technology, the present invention is designed and developed for the heat dissipation structure, and is combined with the vacuum exposure process technology of self-exposure to manufacture the heat sink, and the shortcomings of the above-mentioned existing heat sink are improved and designed. A heat-dissipating / die-casting alloy 'has the thermal conductivity and castability of the material. Using the heat-dissipating structure of the scale-scale alloy, the thermal resistance value is better than that of the ADC12 or 1〇7〇. At the same time, the vacuum-assisted die-casting process can improve the casting age, and the mechanical properties and density of the parts are greatly changed. , Lin's process in the secret management process is much lower.

Ii. Application Principle of the Invention The general heat pipe is composed of the following three elements: a) a closed container (CQntainer); a wick structure; and c) a working fluid (w〇rking fluid). The heat pipe can be divided into three parts: a) an evaporation section (evaporat〇r secti〇n); b) an adiabatic section; and c) a condensation section (condenser secti〇n). The working principle of the secret is the thirteenth and fourteenth figures. After the heating element is in contact with the evaporation section, heat is transferred to the H-wall, capillary structure and working fluid. After the working fluid is heated, it sucks the thief to make money. Since the vapor pressure of the evaporation section is higher than that of the condensation section, the pressure difference is formed, and the flow section of the crane steam flows toward the condensation. When the steam condenses in the condensation section, the latent heat is released, and the heat is transferred to the heat pipe through the capillary structure and the pipe wall. [Because of the New Zealand's Lai, the working brittle surface in the new section forms different y-rate radii in the capillary structure, thus resulting in The capillary force will condense the condensate from the condensing section and complete the work--------------------------------------------------------------------------------------------------------------------------------------------- π·Specification of the Invention 1354882 Supplementary Amendment Date: 100 years 1 month 11th i.
