Description

Technical Field

[0001] The utility model relates to the field of heat dissipation devices, in particular to an alloy base. Background Art

[0002] In the heat dissipation device, water cooling is generally used to dissipate the heat of the computer structure. However, with the development of heat pipes, the heat dissipation base and the heat pipe are combined, and the base and the heating element (such as a graphics card or a CPU) are connected. However, after the heat pipe passes through the indirect heat dissipation of the alloy base, the heat exchange of the heat pipe is performed through the heat dissipation fins, so its heat dissipation effect is affected. In addition, the existing heat pipe is generally U-shaped, so its stroke is relatively long, which also affects the heat dissipation effect of the heat dissipation base.

[0003] Among them, a typical heat pipe consists of a tube shell, a liquid wick and an end cap. After the tube is evacuated to a negative pressure, it is filled with an appropriate amount of working liquid, so that the capillary porous material of the liquid wick close to the inner wall of the tube is filled with liquid and then sealed. One end of the tube is the evaporation section (heating section), and the other end is the condensation section (cooling section). According to application needs, an insulation section can be arranged between the two sections. Utility Model Content

[0004] The main purpose of the utility model is to propose an alloy base, aiming to improve the structure of the existing heat dissipation base, and to improve the heat dissipation effect of the base through different metal materials and the structure of the base and the heat pipe.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an alloy base, comprising:

[0006] A base, wherein the base is provided with positioning grooves arranged at intervals, and a limiting portion is provided between two positioning grooves;

[0007] A heat pipe, wherein a plurality of heat pipes are provided, and the heat pipe comprises an evaporation section and a vertically arranged condensation section, wherein the evaporation section is installed in the positioning groove, and a flat fitting portion is provided on the lower wall of the evaporation section, and the fitting portion is flush with the limiting portion;

[0008] The condensing section is provided with heat dissipation fins, which are formed by stacking adjacent aluminum sheets and copper sheets.

[0009] A plurality of evaporation sections are arranged in parallel, and condensation sections of adjacent heat pipes are staggeredly arranged on opposite sides of the base.

[0010] In the actual design, a simple structure of the heat pipe, i.e., L-type, is used to facilitate the processing of the heat pipe, making its processing cost lower. At the same time, the fitting portion of the heat pipe is set to a structure flush with the limiting portion, so that the heat pipe and the base are in direct contact with the heating element, thereby improving the heat exchange efficiency and effectively improving the heat dissipation effect. Adjacent aluminum sheets and copper sheets are stacked as heat dissipation fins to achieve heat exchange differences in the condensation section, thereby improving the heat exchange efficiency. That is, there is a specific heat difference between the copper sheet and the aluminum sheet, so the gas flow rate in the heat pipe will be faster, that is, the fluid pressure difference is differentiated.
