Drawing preview
Lo scenario

A hybrid vehicle test bench requires separate engine and inverter coolant loops with expansion tanks, heat exchangers, filters, and flow control.

Cosa contiene questo disegno

Leggi le decisioni che ne stanno alla base.

01

Used two independent closed loops with expansion tanks and inline filters

02

Selected motor-actuated fail-closed valve for engine loop and diaphragm fail-open valve for inverter loop

03

Added electric flow transmitters to shared controllers for both loops, plus local temperature indicators

When designing or documenting automotive coolant test rigs that need separate heat-rejection circuits for engine and power electronics.
