Description

This block models a battery cooling plate with multiple channels and a pair of distributor channels for inlet and outlet flow. Use the buildBattery function to create a Simscape model of a battery and connect it to one or both sides of the cooling plate. You can cool any of the four edges of the cooling plate. The fluid_in and fluid_out ports are thermal fluid ports. The output ports are the plate temperature, Tp, the fluid pressure drop, dP, and the fluid temperature change, dT.

Ports

Output
