Design and analysis of heat sinks kraus pdf

  • How are heat sinks designed?

    The most efficient heat sink design from a geometrical standpoint is one that contains fins or pins to increase the surface area for heat transfer.
    Copper is one of the best materials to choose for heat sinks as it has a high thermal conductivity..

  • How do I choose a heatsink for a Mosfet?

    Assuming a 3 mm spacing between MOSFETs, the minimum length of the heat sink required is: 13 mm for a single phase, 29 mm for a two phase circuit and 45 mm for a three phase circuit.
    Minimum width of the heat sink is 15 mm..

  • How is heat sink measured?

    The heat source is assumed to cover the entire base of the heat sink.
    The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling.
    The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink..

  • What are the methods of manufacturing heat sinks?

    Depending on their shapes and materials, heat sinks can be made by many manufacturing methods.
    The most common and cost effective methods include extrusion, forging, casting and stamping.
    Other higher-cost methods include CNC machining, skiving and swaging..

  • What is a heat sink architecture?

    A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature..

  • What is the equation for heatsink design?

    Heatsink design
    We will be using the equation: Tj = Pd (Rjc +Rcs + Rsa) +Ta, where Ta = 2.

    1. C, Tj = 10
    2. C and the values of Rjc and Rcs come from the device data sheets

  • What is the formula for heat sink design?

    Heatsink design
    We will be using the equation: Tj = Pd (Rjc +Rcs + Rsa) +Ta, where Ta = 2.

  • Heat Sink Types

    Passive Heat Sink.
    Passive heat sinks are those that don't rely on forced air flow (fans) and are considered more reliable than active solutions. Active Heat Sink. Aluminum Heat Sink. Copper Heat Sink. Solid Metal Heat Sink. Pumped Liquid Heat Sink. Two-Phase Heat Sink. CNC Machined Heat Sink.
  • Depending on their shapes and materials, heat sinks can be made by many manufacturing methods.
    The most common and cost effective methods include extrusion, forging, casting and stamping.
    Other higher-cost methods include CNC machining, skiving and swaging.
  • Fin shapes.
    Different kinds of heat sink geometries are possible.
    Pin fins, straight fins, fluted fins, wavy fins and fins with non-standard geometry are possible.
    The most common ones are pin fins whose cross section can be round, square, elliptical, hexagonal or any other suitable geometry.

How can a heat sink design improve efficiency?

Using a material that has a higher thermal conductivity and decreasing the aspect ratio of the fins help to boost the fins’ overall efficiency

The following image is part of the results of a simulation investigating the temperature characteristics of a heat sink design

What factors should be considered in heat sink design?

Some of the key factors that should be considered in heat sink design include thermal resistance, material, fin configuration, fin size and shape, fin efficiency, heat sink attachment method, and thermal interface material

Geometries and parameters that provide maximum heat dissipation are obtained by analyzing different heat sink models
