    Fantastic video, just what i needed

    Wait a minute. One of the major points of using a computer to do thermal calculations is for the software to 'figure' out the heat transfer coefficients (natural, forced, radiation view). Faster would be a hand calculation or spreadsheet for this sort of problem. Also what is the cooling fluid and how do you change its properties?

    • @AvivMakesRobots
      @AvivMakesRobots  2 роки тому +1

      Yes, but hand calculations are not going to give you values for every single little crevice of a particular geometry. Think about how much more information you can glean from a gradient map such as this.

    How to consider height of fins in calculation if there height is different? ,as in your case the fins are of different size

    • @AvivMakesRobots
      @AvivMakesRobots  2 роки тому +1

      The main consideration stems from how they break out from the main CPU heatpoint. For this design, I would make the ribs right in the center higher since they are more intimately connected to the CPU and the outer fins shorter to save on size and material.

    I didn't get what is the airflow direction?
    Your heatsink was plaсed with edges parallel to X-Y with Z pointed to the top. If Fusion asumes that your CPU placed at the bottom - ribs will not work as expected.

    • @AvivMakesRobots
      @AvivMakesRobots  4 роки тому +1

      Unfortunately, Fusion does not yet have airflow direction settings. This is a "static" thermal intro in that regard.

    • @AvivMakesRobots
      @AvivMakesRobots  4 роки тому

      The convection value is correct, it just doesn't have a specific direction. Solidworks and Inventor let you dial in more values for these.

    • @DidiWidyaUtama
      @DidiWidyaUtama 4 роки тому

      I think the value for convective coefficient in Fusion is Average value, so doesn’t account the airflow direction. If you want to consider airflow direction, you have to use cfd analysis.

    how can i simulate the greenhouse effect. ii would like to simulate a closed case with a raspberry pi in.

    • @AvivMakesRobots
      @AvivMakesRobots  2 роки тому

      You would set the pi CPU as the main heat source and select the walls of the housing as the containers of the heat.

    Is a simulation like this possible when you have just a sink and no cpu heat source, and no given wattage? Just a temperature from the base, and natural convection

    • @AvivMakesRobots
      @AvivMakesRobots  4 роки тому

      Yes, an implied heat source, but remember that there is no air flow simulation in this study (at least not yet). So your results will be limited.
