GPU thermal management

Generally, the GPU(Graphic Processing Unit) system (we often call it graphic card) has heat sinks such as fins, cooling fan, and water cooler to decrease or maintain the their GPU chip temperature. However, as developing the technologies,  integrated circuit of GPU chip has been increased. As a results, the conventional heat transfer based on conduction and convection has been limited. To maintain the GPU chip temperature, many microelectronic industries are investigated the thermal management. Recently, the micro-heat spreader using phase change heat transfer takes center stage on thermal management on micro-electronic devices.

MEL develops the newest concept of micro-heat spreader using liquid supply layer to handle high heat fluxes, and the experimental set-up, which is imitated the micro-heat spreader.
