Q F Calculating Heat Dissipation Overview s must be mound in a proctive enclosure. The enclosure should be capab of properly dissipating the heat produced by all of the devices mound inside it. This appendix describes how calcula heat dissipation for a . The stragy is calcula a heat dissipation lue in for ea individual in the . obtain a tal heat dissipation figure for the add the individual lues gether. The procedure consists of the following sps: Sp : Basic Method Calcula Dissipation F Sp : Calculation for Power Supplies F Sp : Calculations for Discre s F Sp : Input Calculations for Discre Input s F Sp : Fil Calculation F Infortion Required In addition the infortion in this you will need Specifications . You will need operating current lues for the discre devices connecd the ’s discre s. These include control relays mor starrs soids pilot lights etc. Ea device nufacturer publishes these lues. If an exact lue is t ailab for a device you can ke a close esti by obtaining the lue for a similar device from a catalog. These lues are also needed for secting s during the design process in order ensure that the s’ ratings are t exceeded. F Appendix F Installation and Hardware August Q F Procedure Sp : Basic Method Calcula Dissipation that this sp does t apply Power Supply s whi are covered in Sp . The lues needed for this calculation are found in the Load Requirements tab in apr . Use the following ectrical power formula in these calculations Power in Voltage in volts x Current in . Assume that all input power these s is eventually dissipad as heat. The procedure is: Look up the in the Load Requirements for Hardware ponents tab apr and obtain the current lues for ea of the three power supply voltages lisd. The voltage is prind at the head of ea column. All s use the supply and a relatively few s also use one or both of the two supplies. For a given calcula the power dissipation for ea column in the tab that contains a current lue by multiplying the current lue in times the voltage for that column. For s using more than one voltage add the calculad power lues arrive at the tal for the . Examp : The Load Requirements tab shows that the IC draws: from the + supply. current from either of the two supplies calcula power dissipation multiply . times volts. The answer is: . of heat dissipad by this Examp : The Load Requirements tab shows that the draws: from the + supply from the + Isolad supply calcula power dissipation from the + supply: Multiply . times volts arrive at a lue of . . calcula power dissipation from the + supply: Multiply . times volts arrive at a lue of . . Adding the two gether yields a tal heat dissipation by this of .
