Abstract
The invention relates to a heat sink for an electronic board of a motor vehicle motor-driven fan unit, comprising a surface (2) intended for exchanging heat with an air flow set in motion by the motor-driven fan unit, referred to as exchange surface (2), said exchange surface (2) comprising a planar portion (3) arranged so that, in a position installed in the motor-driven fan unit, the air flow set in motion by the motor-driven fan unit flows substantially parallel to said planar portion (3), the exchange surface (2) also comprising a set of blind recesses (4) flush with said planar portion (3).
