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).
Claims5
A heat sink for an electronic board of a motor-driven fan unit of a motor vehicle, comprising
- an exchange surface configured for exchange of heat with an air flow set in motion by the motor-driven fan unit, said exchange surface comprising:
- a planar portion configured such 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;
- and
- a set of blind cavities flush with said planar portion,
- wherein each blind cavity comprises a part in a form of a truncated pyramid on a polygonal base and/or a part of constant cross section, and
- wherein the polygonal base is a hexagonal base.
