Creation Instructions (1) [Technical Field of New Type] This creation is about a heat sink, especially a heat sink that uses the phase change principle to dissipate heat generated by electronic components. [Previous technology] With the rapid development of the electronics industry, the computing speed of electronic components such as central processing units (CPUs) has greatly increased, and the heat generated by them has also increased dramatically. How to radiate the heat of electronic components to ensure Its normal operation has always been a problem for industry research. The traditional heat dissipation method is to set a heat sink made of metal material above the heating electronic component. The heat sink has a base, the lower surface of the base is in contact with the electronic components, and the upper surface is provided with a plurality of fins, and the base absorbs the electronic components. The generated heat is radiated to the surrounding air through the fins. To enhance the heat exchange speed between the fins and the surrounding air, a fan is usually added above the fins to enhance gas convection. Although the above-mentioned heat dissipation device can dissipate part of the heat generated by the electronic components, it simply conducts heat through a metal heat sink, and the thermal conductivity of the metal is limited, which results in a limited heat conduction amount of the heat sink per unit time and unit volume. The traditional pure metal radiator underheating method can no longer meet the south heat generation. At present, the industry uses heat pipe conduction heat pipes to seal the metal pipe with knots, groove structures, wire mesh structures, etc.) and evacuate to vacuum. The state absorbs and releases heat through the process of industrial changes. The heat sink has the heat dissipation requirements of electronic components which are arranged on top of each other and are flat to each other. There are more and more heat dissipation devices. Capillary structures (such as metal powders) and working liquids (such as water and alcohol) are used as liquids to perform liquid-gas two-phase heating. Commonly used heat pipe cooling devices include two metal flat plates, one of which is flat.

Creation instructions (2) The board and the heating electron tube are roughly “Un” shape; the inner side of the plate is soldered from pure gold to one of the plates. In terms of thermal performance, there is a kind of heat dissipation sub-element when the heat pipe is produced. [Content] The heat generated by the invention is warmer at the flat part, but the heat of the electric part is changed due to the hot metal level in the larger device. In this creative phase change, there is one tube. Each inner wall is provided with a capillary tube flow channel at both ends and at least one tube flow channel. The thin structure is attached to the pieces. The two flat plates are provided with a plurality of fins to heat the two parallel sections. The two flat plates of the heat sink are respectively inserted and fixed to the heat sink. Because the heat sink is made of two materials, although the heat generated by the electronic components is conducted, but due to the limited thermal conductivity of the metal, most of the center of the board and the electronics Where the components are in contact, and the plate has a low distance, although the heat distribution to the plate is not uniformly distributed through the heat pipe with a high thermal conductivity, the heat distribution is not uniform, and it is quickly dissipated, which affects Thermal effect; the other is to connect the panel and the board by soldering. The 'different thermal property' of the solder paste guide plate causes the thermal resistance caused by the heat transfer from the panel to further affect the heat dissipation effect. How to provide f can use the phase change principle to quickly Efficiently dissipating electricity ΐ is the problem to be solved by the author. The purpose is to provide a heat dissipation device that can quickly and effectively dissipate electronic components. The heat dissipation device includes two parallel plates and the plate is hollow.
