OBC & Inverter Test Cooling System
Product Description
OBC (onboard charger) and DCDC (DC-DC converter) are the core components of electric vehicles, and the functional quality of DCDC and OBC is critical to the performance and safety of the entire vehicle. During the development and testing of OBC and DCDC, as well as the entire vehicle, a comprehensive test of the functions and performance of OBC and DCDC is required.

| Closed circulation system |
The whole system is a fully enclosed system. There is no oil mist at high temperature, and low temperature does not absorb moisture in the air. The system does not increase the pressure due to high temperature during operation, and the heat medium is automatically replenished at low temperature. | ||||||
