Heat Sink heatsink.pngQfin is the ultimate tool for designing and optimizing heat sinks. Heat sinks can be obtained from libraries, created through wizards or by importing it as CAD objects. Heat sinks can be converted to compact models or combined with other components such as heat pipes, fans and openings. Results can be obtained with the system CFD solver within minutes, while the detailed CFD solver provides the option of detailed system level solutions. 'Surface to surface' and 'surface to ambient' radiation is included with the click of a button and stability with natural convection applications is a key feature. More details... Cold Plate coldplate_0.pngQfin allows the user to design basic serial and parallel configurations through a easy to use module. More complex configurations can be created from the user interface or simply imported as CAD objects from STEP files. Non CAD geometries can be solved in minutes using the system CFD solver, while complex CAD configurations can be solved using the detailed CFD solver. Detailed inlet effect can therefore be included in the designs. More details... LED Applications led.pngQfin is the ideal platform to design complex LED assemblies. The new LED module assists the user, through a step by step process, in defining a dynamically coupled LED module. This information is linked to the specific LED and saved in a database. The LED can therefore be added to any new project and the characteristic information of the LED will be used to ensure optimal thermal results. Heat sinks can be designed through the user interface or imported as CAD objects and the detailed report shows LED efficiency. More details... TEC/TEG Applications tec_teg.pngThe TEC module in Qfin is simple to use and allow the user to specify different levels of detail. The thermal model is based on a full 3D discretization of both the fluid and solid parts and account for nonlinear Joule and Thomson effects, radiation as well as electrical and thermal resistances. Fully integrated with the fast System CFD solver or the Detailed CFD solver this module can beused to design or analyse any TEC or TEG application. More details... Heat Pipes heatpipes.pngHeat pipes can be designed or added to any system from either the user interface or by importing the heat pipes as CAD objects. Board level analysis boardlevel.pngPC boards and attached components can be modelled efficiently in Qfin using a basic or compact model for the PCB or simply creating any layered board from the user interface. Components can be added with interface resistances to different layers of the board and solved as a conduction application only, or coupled to convection boundaries. System Level Modeling systemlevel.pngComplex systems can be designed by using basic components from the user interface. The systems can be solved and optimized in minutes using the system CFD solver and all results can be validated at any point by using the detailed CFD solver. Enclosures enclosures.pngBy using local boundaries, Qfin can simulate the flow and heat transfer in detail inside any enclosure, while the heat transfer to the environment is dynamically updated, between iterations, based on the surface temperature of the enclosure. Range Solve Option rangesolve.pngThe range solver allows the user to investigate the effect of single parameters on the solution. The user can for instance investigate the effect of the position of the a fan on the solution. Mathematical Optimization mathematical_optimization.pngMathematical optimization allows the user to optimize designs in terms of geometry, location or operating condition to optimize the design and thereby minimize the manufacturing cost of the component or assembly. Transient simulations The system CFD solver in Qfin allows the user to simulate transient applications very efficiently. In particular systems exposed to natural convection.
