CoolMag Thermo Conductive: A new disruptive solution for thermal management in power electronics

Sponsored by Coolmag

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 materialsElectric isolationMechanical protectionFlame 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.

The Benefits?

No air, no plastics, no epoxies, no VOCSNo magnetic strictionNo saturation of core No reduction of copper conductivityThermal dissipation in 3DFire 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.
