To design a sealed thin-sheet BAKSA steel box<\/strong> for a 150W PC<\/strong> with the given ambient temperatures, we need to ensure the box is large enough to dissipate heat purely through conduction and natural convection<\/strong> without exceeding safe internal temperatures.<\/p>\n\n\n\n

\n\n\n\n

Key Parameters:<\/strong><\/h3>\n\n\n\n
    \n
  • PC Heat Output (Q):<\/strong> 150W<\/li>\n\n\n\n
  • Max Internal Ambient (T_internal):<\/strong> 55\u00b0C<\/li>\n\n\n\n
  • Max External Ambient (T_external):<\/strong> 45\u00b0C<\/li>\n\n\n\n
  • Material:<\/strong> BAKSA steel (assuming similar to mild steel, thermal conductivity ~50 W\/m\u00b7K<\/strong>)<\/li>\n\n\n\n
  • No fans\/vents<\/strong> \u2192 Only passive cooling<\/li>\n<\/ul>\n\n\n\n

    Step 1: Calculate Required Surface Area for Heat Dissipation<\/strong><\/h3>\n\n\n\n

    The heat must escape through the steel walls via conduction + convection<\/strong>.<\/p>\n\n\n\n

    Formula:<\/strong><\/h4>\n\n\n\n

    Q=h\u22c5A\u22c5\u0394TQ=h\u22c5A\u22c5\u0394T<\/p>\n\n\n\n

    Where:<\/p>\n\n\n\n

      \n
    • Q<\/strong> = Heat to dissipate (150W)<\/li>\n\n\n\n
    • h<\/strong> = Effective heat transfer coefficient (estimated ~10 W\/m\u00b2\u00b7K<\/strong> for passive steel)<\/li>\n\n\n\n
    • A<\/strong> = Surface area needed (m\u00b2)<\/li>\n\n\n\n
    • \u0394T<\/strong> = Temperature difference (55\u00b0C – 45\u00b0C = 10K<\/strong>)<\/li>\n<\/ul>\n\n\n\n

      Solving for A:<\/strong><\/h4>\n\n\n\n

      A=Qh\u22c5\u0394T=15010\u00d710=1.5\u2009m\u00b2A=h\u22c5\u0394TQ\u200b=10\u00d710150\u200b=1.5m\u00b2<\/p>\n\n\n\n

      Required Surface Area \u2248 1.5 m\u00b2<\/strong><\/p>\n\n\n\n

      <\/p>\n\n\n\n

      Step 2: Determine Box Dimensions<\/strong><\/h3>\n\n\n\n

      We need a box with at least 1.5 m\u00b2 of external surface area<\/strong>.<\/p>\n\n\n\n

      Assuming a Cuboid Shape (L \u00d7 W \u00d7 H):<\/strong><\/h4>\n\n\n\n

      A=2(LW+LH+WH)A=2(LW+LH+WH)<\/p>\n\n\n\n

      To minimize size, let\u2019s assume a cube-like shape<\/strong> (L \u2248 W \u2248 H):A=6L2\u2192L=A6=1.56\u22480.5\u2009m (50 cm)A=6L2\u2192L=6A\u200b\u200b=61.5\u200b\u200b\u22480.5m (50 cm)<\/p>\n\n\n\n

      Minimum Internal Dimensions:<\/strong><\/p>\n\n\n\n

        \n
      • 50 cm \u00d7 50 cm \u00d7 50 cm<\/strong> (if perfectly cubic)<\/li>\n<\/ul>\n\n\n\n

        <\/p>\n\n\n\n

        \"\"<\/figure>\n\n\n\n

        <\/p>\n\n\n\n

        But PCs are Rectangular \u2192 Optimize Shape<\/strong><\/h4>\n\n\n\n

        If the PC is 30cm \u00d7 30cm \u00d7 15cm<\/strong>, we can adjust:<\/p>\n\n\n\n

          \n
        • Add 10cm clearance<\/strong> \u2192 Internal box = 40cm \u00d7 40cm \u00d7 25cm<\/strong><\/li>\n\n\n\n
        • External Surface Area<\/strong> = 2(0.4\u00d70.4 + 0.4\u00d70.25 + 0.4\u00d70.25) = 0.92 m\u00b2<\/strong> (Still too small!)<\/li>\n<\/ul>\n\n\n\n

          \u2192 Must increase size further.<\/strong><\/p>\n\n\n\n

            • Surface Area = 2(0.6\u00d70.6 + 0.6\u00d70.3 + 0.6\u00d70.3) = 1.44 m\u00b2 (~1.5 m\u00b2 achieved)<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

              Step 3: Enhance Cooling (If Box Must Be Smaller)<\/strong><\/h3>\n\n\n\n

              If a 60\u00d760\u00d730cm box is too large<\/strong>, consider:<\/p>\n\n\n\n

                \n
