Esempio di applicazione (case study) sui radiatori per veicoli elettrici


A manufacturer of electric vehicles sought Aavid, Thermal division of BoydCorporation, in a thermal design challenge with cooling their radiator. Aavidwas tasked to develop a practical solution while meeting a strict cost per unitin production.



La sfida

The manufacturer of the Electric Vehicle needed thermal expert analysis to makea reliable product in a new overall product design feature. Focusing on the unit'sradiator and existing Folded Fin structure Aavid was tasked to simulate abaseline design and optimize fin spacing and thickness to meet the requirementsof the customer. Tra gli obiettivi vi erano:

• Studio sulla struttura delle feritoie di ventilazione delle alette.
• Ottimizzazione della distanza e dello spessore delle alette.
• Ottimizzazione dell'aletta più alta di 5 mm.
• Studio sullo spessore della piastra di supporto.
• Indagini comparative sull'uso dell'alluminio o del rame per le alette e la base di supporto.

La soluzione

Aavid’s lab tested the louver structures to examine the impeding airflowand increase the pressure drop across the heat sink and their thermalperformance.

Una volta tratte le conclusioni, Aavid ha creato un riepilogo sull'ottimizzazione delle alette. For theAluminum and Cooper bases, testing showed by using cooper performanceincreased by 5C.

It was discovered that the overall airflow management system needed to beoptimized in a way of minimizing flow turns and flow direction changes as well asflow sudden expansion and contraction.

Esito finale

Aavid presented the customer with a full presentation report which included:descriptions of the unit and components modeled, color temperature contourand flow field vector plots, key results, conclusions, and recommendations forimprovements.

The manufacture took this report and selected the proper thermal solution vs.cost. Oggi Aavid risponde alle sue esigenze produttive a livello internazionale.
