Abstract
Description
Technical Field
[0001] The invention relates to a heat dissipation element combination structure, in particular to a heat dissipation element combination structure which improves the two-phase flow circulation between a heat pipe and a temperature equalizing plate by combination. Background Art
[0002] Heat pipes and vapor chambers are the most commonly used heat conduction elements in the field of heat dissipation. Although heat pipes and vapor chambers use the same technical principles, their heat conduction characteristics are different. Heat pipes are far-end axial heat conduction, while vapor chambers are large-area surface-to-surface heat conduction. Therefore, if only heat pipes or vapor chambers are used, both far-end axial heat conduction and large-area surface-to-surface heat conduction cannot be achieved simultaneously.
[0003] Currently, some manufacturers combine heat pipes with temperature-averaging plates to connect the airtight chambers of the two. Figure 1 As shown in the figure, the temperature equalizing plate 4 is provided with a hole 42 on the upper plate body 41 for the heat pipe 5 to be plugged in, and the open end of the heat pipe 5 is abutted against the lower plate body 43 of the temperature equalizing plate 4, and the heat pipe 5 is accommodated in the portion of the chamber 44 of the temperature equalizing plate 4. In order to make the chamber 51 of the heat pipe 5 and the chamber 44 of the temperature equalizing plate 4 communicate with each other for vapor-liquid circulation, a slot 52 is radially opened in the portion, so that the heat pipe 5 and the capillary structures 53, 45 in the chamber 44 of the temperature equalizing plate 4 and the chamber 44 can be communicated with each other for vapor-liquid circulation.
[0004] Although the above-mentioned prior art has the heat conduction characteristics of both the temperature equalizing plate 4 and the heat pipe 5, it is not without disadvantages. When the open end of the heat pipe 5 extends to the lower plate 43 of the temperature equalizing plate 4, it will occupy the space of the chamber 44 of the temperature equalizing plate 4, increasing the resistance to the flow of steam. Moreover, if the heat pipe 5 is not extended to abut the lower plate 43 of the temperature equalizing plate 4, in addition to making it impossible for the capillary structures 53 and 45 inside the heat pipe 5 and the temperature equalizing plate 4 to be connected, thereby making it impossible for the condensed working liquid to flow back, the heat pipe 5 has no support and is prone to deflection and detachment. Therefore, how to improve the existing deficiencies has become the primary goal of people in this field. Summary of the invention
