Electrical Device for Use in an Automotive Vehicle and Method for Cooling Same

摘要

An electrical device is described for use in an automotive vehicle. The device includes a printed circuit board (PCB) having first and second sides. The PCB is adapted for multiple electronic components to be mounted to the first side, including a first component at a first position and a second component at a second position. The second component is capable of substantially blocking airflow directed substantially across the first side from at least one direction toward the first component. The PCB defines a plurality of apertures formed in a region of the PCB including the first position such that airflow directed substantially across the second side of the PCB flows through the apertures, under the first component at the first position on the first side of the PCB, and on a portion of the first side of the PCB beyond the region of the PCB including the first position.

1. An electrical device for use in an automotive vehicle, the device comprising:
a printed circuit board (PCB) having a first side and a second side; and a plurality of electronic components mounted to the first side of the PCB, the components comprising a first component located at a first position on the first side of the PCB and a second component located at a second position on the first side of the PCB, the second component located at the second position capable of at least partially blocking airflow directed substantially across the first side of the PCB in at least one direction toward the first component; wherein the PCB defines a plurality of apertures therethrough, the apertures formed in a region of the PCB comprising the first position such that airflow directed substantially across the second side of the PCB flows through the apertures, under the first component at the first position on the first side of the PCB, and on at least a portion of the first side of the PCB beyond the region of the PCB comprising the first position.
