CoolMag TC is a young customer-centric organization that offers passive solutions in thermal management for EV Power Electronics. Manufacturing resins and thermoplastic compounds that offer the following advantages:
- Thermally conductive materials
- Electric isolation
- Mechanical protection
- Flame and fire protection (retardant and extinction)
Top applications for CoolMag Thermo Conductive are power transformers and semiconductors, on-board chargers (OBC), inverters and DC/DC converters, high-reliability power electronics, inter-cell coating and protection in batteries and gap filler to interface with liquid cooling in battery packs.
The above pictures represent (1) a Common Choke for an OBC’s (On Board Charger).
(2) The steady state temperature is so high (over 183ºC) that materials cannot support it. So, a thermal mechanism to sink the generated heat is needed.
(3) After a Coolmag 29LV (Silicone based compound) injection process, the whole CMC is encapsulated, so 100% of the empty gaps within the choke are filled with Coolmag. Thereby, air within the CMC is replaced by a thermally conductive material.
Temperature drops dramatically up to 80ºC, as Coolmag provides a great thermal coupling to sink the heat at the cooling plate.
- No air, no plastics, no epoxies, no VOCS
- No magnetic striction
- No saturation of core
- No reduction of copper conductivity
- Thermal dissipation in 3D
- Fire and mechanical protection(UL 94 V0)
- High thermal diffusivity
Now, Coolmag offers an all-in-one solution called Coolmag-as-a-Service. From prototype encapsulation process to production, with final customized dispensing machines for the best product potting.
