1. A light detection and ranging (LIDAR) system for a vehicle, the LIDAR system comprising:
a lid defining an internal volume;
one or more circuit modules disposed within the internal volume;
a cold plate including a heat treatable metal alloy, the cold plate further including:
a first side coupled to the lid to enclose the one or more circuit modules within the internal volume defined by the lid, and
a second side that is different from the first side and defines a fluid channel through which a liquid coolant flows; and
a cover including a magnesium free metal alloy or a low magnesium content metal alloy, the cover being coupled to the cold plate to cover the fluid channel defined in the second side of the cold plate.
