Description

Technical Field

[0001] The utility model belongs to the technical field of heat sinks, and more specifically, particularly relates to a copper-aluminum composite heat sink provided with a capillary plate. Background Art

[0002] Most electronic devices use copper-aluminum composite heat sinks to dissipate heat from electronic components (such as chassis). The inner side of the copper-aluminum composite heat sink is usually provided with a capillary plate to conduct heat from the electronic components through the copper-aluminum composite heat sink, and then the copper-aluminum composite heat sink is cooled by a fan to dissipate heat from the electronic device.

[0003] For example, CN212109686U discloses a vapor-liquid diversion capillary core heat exchanger and a preparation method, which belongs to the field of electronic device heat dissipation technology and is composed of a steam chamber, fins and a heat dissipation fan. The present invention has a simple structure, and the steam chamber is filled with an integrally sintered capillary core, which is divided into an upper capillary core and a lower capillary core, wherein the upper capillary core is processed with a tree-like steam channel; the phase change medium filled in the steam chamber absorbs heat and then boils and evaporates, and flows to the side wall and upper wall of the steam chamber in the tree-like steam channel in the steam chamber and condenses for heat exchange; other capillary core structures except the steam flow channel are used to draw the condensate back to the heated area to form a working cycle, and the gas phase medium and liquid phase medium in the steam chamber flow in the steam channel and the capillary core respectively, reducing the mutual influence during the flow of the two-phase medium, which is conducive to the rapid diffusion of steam to the condensation surface for heat exchange, and the timely return of the condensate to the hot end of the heat exchanger; the heat exchange performance of the heat exchanger can be effectively improved.

[0004] Based on the above, since the installation space inside electronic devices is usually small, the heat sink fins of the copper-aluminum composite heat sink are easily squeezed during installation, causing deformation or wear of the heat sink fins, affecting the use effect of the heat sink, and further affecting the heat dissipation effect of the electronic components.
