Embodiment Construction

[0031] The invention relates to a heat sink for an electronic board of a motor-driven fan unit of a motor vehicle. The radiator is indicated with 1 in the figure.

[0032] The motor-driven fan unit preferably forms part of a heating, ventilation and / or air-conditioning arrangement of the motor vehicle.

[0033] The motor-driven fan unit is designed to initiate an air flow, which is preferably destined to the interior of the motor vehicle. air flow in Figure 4 Expressed in F. Figure 4 An electronic board 50 and high power electronic components 51 are also depicted. This component may be a power transistor for controlling the electric motor of the motor driven fan unit. For example, the transistor may be an Insulated Gate Field Effect Transistor, whose acronym is "MOSFET."

[0034] From Figures 1 to 5 It can be clearly seen that the heat sink 1 comprises a surface 2 for heat exchange with the air flow F, referred to as the exchange surface 2 . The air flow F exchanges ...

Abstract

The invention relates to a heat sink for an electronic board of a motor vehicle motor-driven fan unit. The heat sink comprises 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), the exchange surface (2) comprises a planar portion (3) arranged so that, at 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), and the exchange surface (2) also comprises a set of blind recesses (4) flush with the planar portion (3).

Description

technical field [0001] The invention relates to a heat sink for an electronic board of a motor-driven fan unit of a motor vehicle. Background technique [0002] Preferably, such a motor-driven fan unit forms part of a heating, ventilation and / or air-conditioning arrangement of a motor vehicle, which regulates the temperature of an air flow intended to supply the vehicle interior. [0003] The motor drives the fan unit itself for causing the air flow to enter and circulate in the heating, ventilation and / or air conditioning unit until the air enters an outlet opening in the vehicle interior. [0004] A motor-driven fan unit in a known manner comprises an electric motor, eg with brushes, on which an impeller is mounted to move the air, and means for controlling the electric motor, the electric motor control comprising an electronic board. [0005] In a motor driven fan unit, the purpose of the heat sink is to cool the components of the motor control electronics board, especia...
