Thermal Desktopde C&R Technologies
Thermal Desktop es un entorno de desarrollo basado en PC para la generación de modelos térmicos de vehículos y dispositivos electrónicos. Con Thermal Desktop, los ingenieros pueden usar sus diseños CAD directamente como un modelo térmico, o indirectamente como un esqueleto al que añadir elementos de Thermal Desktop, superficies y partes sólidas.
Thermal Desktop is a PC based design environment for generating thermal
models of electronics and vehicles. Using Thermal Desktop, engineers can use CAD
drawings either directly as a thermal model, or indirectly as scaffolding for
fast "snap on" attachment of Thermal Desktop elements, surfaces, and solids.
Thermal Desktop incorporates both familiar parameter based (TRASYS like)
finite difference surfaces with finite elements with CAD technology to model
thermal problems. Thermal Desktop develops the capacitance and conductance
network for input to SINDA/FLUINT. Thermal Desktop has thermal analysis specific
type of capabilities such as applying contact conductance, insulation, heat
loads, and heaters.
Thermal Desktop provides full design parameterization using spreadsheetlike
variables and arbitrarily complex expressions as input, rather than hardwired
numbers. This allows complex models to be rapidly manipulated using a few
keystrokes, meaning that updating or maintaining a model is trivially easy, as
is performing sensitivity studies and investigating whatif scenarios. This
provides access to SINDA/FLUINT's Optimization and Reliability Engineering
modules, which can be used to size components, maximize performance, find worstcase
operating conditions (design cases), correlate models to test data, and even
treat uncertainties statistically.
Thermal Desktop is available for PC as a standalone tool (no external CAD
package required) or as an AutoCAD extension module. The following addon
modules are available to expand the capabilities of Thermal Desktop:
 RadCAD® is an optional thermal radiation analysis module for high
temperature and/or vacuum applications.
 FloCAD? adds the capability of modeling flow circuits, including fans
and convective heat transfer, attached directly to the surfaces and solids.
