Hvordan optimalisere design av kjøleribbe

      Heatsink  is a component that cools a device by dissipating heat. It can be used for both passive cooling and active cooling systems (e.g. combined with fans). When you optimize the design of the heatsink, you can turn to simulation. For the design of heatsink, the most important consideration is the heat dissipation performance of heatsink under a given configuration, including flow properties and geometric layout.

      A benchmark test of thermal performance is to place the heatsink in a rectangular channel equipped with thermal insulation wall, and then measure the temperature and pressure at the inlet and outlet of the channel. At the same time, it is also necessary to measure the power value required for the heat dissipation substrate to maintain a specific temperature. Finally, the benchmark results show the heat dissipated by the heatsink and the pressure drop of the channel.

     When running the thermal optimization simulation, we only need to input some basic information of the heatsink and it's working conditions. The thermal  simulation software will automatically calculate the detailed perfomance :

Bredde, dybde og tykkelse på radiatorbunnplaten

Antall finner

Finnehøyde og tykkelse

Driftsforhold:

innløpshastighet og temperatur

Varmekildens temperatur

            Ved ganske enkelt å endre inngangsparametrene, kan vi intuitivt observere hvordan endringen av finnetallet påvirker den tapte kraften og trykktapet. Selv uten profesjonell bakgrunn innen simulering, kan brukere bruke resultatene til å lage en ideell radiatordesign.
