Description

Field of the invention

The present invention relates to the field of heat dissipation, and more particularly, to a two-phase heat transfer structure which can reduce the heat exchange area and shorten the heat transfer path and improve heat transfer efficiency.

State of the art

Frequently used cooling techniques for electronic products are fans and cooling fins. As the performance of current electronic devices increases, electronic components used for signal processing and computation generate ever-increasing heat as compared to previous electronic components. Two-phase heat transfer technology is used for heat dissipation of products or in high heat flow environments. Based on the theory of phase change, the heat flux can reach more than 50 W / cm ² and does not require additional electricity. The two-phase heat transfer technology thus has the properties of good heat transfer and energy saving.

In the two-phase heat transfer technique, there are loop heat pipes (LHP), capillary pumped loops (CPL), gas-liquid two-phase loop thermosiphons (LTS), etc. The device of the two Phase heat transfer technology typically includes an evaporator connected to a radiator, the two being interconnected by a steam tube and a liquid tube to form a closed loop, the heat being transferred through the vapor tube from the evaporator to the distal radiator, so as to ensure heat dissipation.

However, in condensers used in the two-phase heat transfer technology, the temperature and heat are lowered by means of fans. The cooling of the fan requires in addition to the larger heat exchange surface a larger footprint in the system. In addition, the heat transfer path of conventional steam pipes and liquid pipes is longer, so that working medium in the steam pipe and liquid pipe can not quickly flow back, resulting in poor heat transfer efficiency. How the system space can be used to meet the requirements of heat exchanger replacement or how the heat transfer efficiency of the fan can be surpassed is therefore of great importance to the related industry and represents an important research direction.
