Software analyserer køling af elektronik

Mentor Graphics har præsenteret FloEFD værktøjet til simulering bl.a. af kølingssystemer i elektronikkonstruktioner.

Mentor Graphics has announced the FloEFD [Engineering Fluid Dynamics] v9.0 product suite from the company’s Mechanical Analysis Division (formerly known as Flomerics), with functionality specifically targeted for simulation and analysis of electronics cooling applications.

As a 'CAD-Embedded' application, the FloEFD suite tightly integrates with all popular MCAD design solutions to enable mechanical designers to easily analyze sophisticated electronic products including those with complex geometries.

The FloEFD suite now complements Mentor’s FloTHERM product line to cover analysis by both the mechanical designer as well as the thermal analysis specialist. With FloEFD, the simulation models are easily and directly generated from the design database while in the MCAD environment, thus enabling a seamless, streamlined design flow for optimum designer productivity and accuracy.

Moreover, with analysis capabilities readily available to the designer, more simulations will result in higher product reliability and fewer prototypes/manufacturing re-spins.

- With the addition of FloEFD to our family of electronics cooling simulation tools, we now offer a complete solution for the thermal analysis of complex electronic products, says Roland Feldhinkel, product line director for the Mentor Graphics Mechanical Analysis Division.

- Based on our powerful EFD analysis engine, FloEFD is able to quickly and accurately analyze thermal effects in designs including those with complex geometries and curved surfaces. And, by embedding this functionality directly into the MCAD environment, we have improved the productivity of the designer, made easy-to-use analysis available to the entire design team, and enabled our customers to improve the reliability of their products by managing thermal effects, he says.

Developed by the same team behind the FloTHERM product, the FloEFD suite offers a single environment to develop, analyze, and modify a complex electronic product design based on the original mechanical CAD model. Changes to the design are made directly and simply thereby enabling users to conduct 'what-if' analysis effortlessly. Products can be easily optimized for electronics cooling due to the availability of several key features:

Joule heating allows for accurate modeling of the physics in applications where heat is an unwanted by-product of current use; for example, load losses in electrical transformers

Heat pipe compact models offer a simple and pragmatic method for modelling a predominant cooling approach in space-constrained or conduction cooled designs

Access to wide range of engineering databases and libraries for fans, thermoelectric coolers, two-resistor components and IC packages enable users to create accurate models quickly.
