AI Technical Summary

Technical Problem

The flow channel design of existing server heat sinks cannot take into account both efficient heat dissipation under high load conditions and normal energy saving requirements, resulting in uneven energy consumption. In addition, existing technologies cannot flexibly adjust the flow channel structure to adapt to different load conditions.

Method used

A multifunctional liquid-cooled heat sink is designed. Through the combination of a separating liquid sac, a blocking liquid sac and a thermal conduction plate, flexible switching and adjustment of the flow channel can be achieved. It can switch between the high heat dissipation state of the parallel flow channel and the low energy consumption state of the series flow channel. The flow resistance can be dynamically adjusted by combining the regulating liquid sac and the solenoid valve group to adapt to the heat dissipation requirements of different load states.

Benefits of technology

It achieves a balance between efficient heat dissipation under high load conditions and energy-saving heat dissipation under normal conditions, improves heat dissipation uniformity and energy efficiency, reduces energy consumption, and adapts to different server load requirements.

Abstract

The present invention relates to the technical field of server liquid cooling systems, and in particular to a multifunctional liquid cooling heat sink for a liquid cooling system. It comprises a mounting plate, the mounting plate being fixedly connected to a sealing bottom plate, two flow cavities being symmetrically distributed and interconnected on only one side being provided between the mounting plate and the sealing bottom plate, the mounting plate being fixedly connected to a partitioning liquid capsule and a shielding portion distributed at intervals within the flow cavity, the partitioning liquid capsule and the shielding portion being used together to divide the flow cavity into a plurality of flow channels, the mounting plate being fixedly connected to a symmetrically distributed first blocking liquid capsule and a symmetrically distributed second blocking liquid capsule. The present invention changes the flow path of the coolant within the flow cavity by means of the partitioning liquid capsule, the first blocking liquid capsule and the second blocking liquid capsule, so that the device can switch between a high heat dissipation working state of a parallel flow channel and a low energy consumption working state of a series flow channel according to the server load conditions, so that one heat sink can achieve two different heat dissipation functions.
