Title:
RECORDING MEDIUM, AND THERMAL ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/044878
Kind Code:
A1
Abstract:
The computer-readable recording medium has recorded thereon a thermal analysis program for causing a computer that analyzes the temperature of a resistor provided with an intermediate portion which is separated from a base board, and, on both sides thereof, terminal portions which are connected to wiring on the base board, to execute: a procedure for preparing a thermal analysis model; a procedure for setting a predetermined amount as the amount of heat generated by an intermediate node that simulates the intermediate portion in the thermal analysis program; and a procedure for analyzing the temperature of the resistor using the thermal analysis model. The thermal analysis model includes: the intermediate node; a terminal node which simulates at least one of the terminal portions on both sides, and which serves as a starting point of a first pathway that transfers heat from said one terminal portion toward the base board that is in contact with the wiring; and a thermal resistance connecting the terminal node to the intermediate node. The thermal analysis model includes a split node that simulates a boundary splitting the wiring into a joined part to which said one of the terminal portions is joined, and another wiring part, and that serves as the end point of a second pathway conducting heat from said one terminal portion to the wiring boundary, wherein the second pathway connects the terminal node and the split node.
