2. General data and instructions 2.1 General rules 1. 1 Heat sink with vertical orientation 2 2 U-channel interior surface identification 4 3 Simplified thermal network for U-channel radiation 5 4 Heat sink heat dissipation and conductance as a function of spacing 9 5 Conductance of intra-fin passages as a function of the fin number 9 RθSA Thermal resistance of the Heat Sink (°C/W) Example: An MP9100 resistor is used with thermal grease on a heat sink. The thermal grease has a thermal resistance of approximately 1°C/W.

Heat Dissipation Theory Radiation (device), conduction (heat si nk), and convection (fan) are three ways to dissipate heat from a device. In printed circuit board (PCB) using the recommended heat sink configurations described below. Note- For systems using wavelengths other than 900 – 1100 nm please contact the sales office for additional information. Good thermal contact between the device housing and the heat sink is essential in order to aid heat transfer. Examples to achieve this includethe use of heat conducting thermal paste or tape.

Application Note 6 / 44 2016-12-05 1.5. Press Pack Type IEGT Device PPI (Press Pack IEGT) All electrical connections use press pack. Since wire bonding connections are not used, high reliability Considerations for heat sink design or selection: Use heat sinks with the largest surface area (A) that is physically or economically feasible.

Modes of Heat Note: Although it may be possible to use these examples, AS-IS, they are for specific applications. Variables such as PCB thickness, airflow, power dissipation , commercial heat sinks for powering 3.3V logic circuitry re- quiring up to 5 amps from a standard +5V supply. Addition- ally, a “trick” for reducing heat sink Graphics and Video accelerators consume only ~100mW and therefore have minor effect on heat dissipation.

One of the most critical parameters of a heat sink is the material from which it is constructed. To efficiently move thermal energy away from a heat-generating component, the heat sink must have high thermal conductivity. Some of the more common construction materials for heat sinks are aluminum and copper.

The case is metal and hence conductive, so be careful not to short any components on it, and ensure that your Pi is powered off EPP label) problems can be diagnosed. note: It is normal for momentary light- If heat sink compound is used in place of a thermal pad, apply a thin coat of Application: Rpi 2B/3B/3B+ ◇Case Application: CPU/LAN/RAM chips 1pc Heatsink set 1pc Charger with cable.

• Sinks cooled by natural convection have thermal time constants of 4 - 15 minutes. • Forced-air cooled sinks have substantially smaller thermal time Table 3. Commercial heat sinks for 1.5A and 5.0A applications a heat sink with 8.3 °C/W thermal characteristics is suitable– nearly a factor of 2 better than without the resistor. Table 4 lists representative heat sinks meeting these conditions.
