Title: Rody El Chammas: Thermal Management Innovations for Electrified Vehicles.
Introduction
Rody El Chammas is an inventor based in La Verrière, France, whose patent work focuses on thermal management and conditioning systems for hybrid and electric vehicles. He is associated with Valeo Systèmes Thermiques and holds 3 patents.
Latest Patents
El Chammas’s listed patents address ways to manage heat and refrigerant flow in vehicle climate-control systems.
- **Thermal management system for a hybrid or electric vehicle.** This invention describes an air-conditioning circuit with a two-fluid heat exchanger integrated into a heat-transfer-fluid circuit. The circuit includes a first branch with a pump and a heating device, as well as a second branch connected directly to the first. In heating mode, the system directs all heat-transfer fluid leaving the heating device through the two-fluid heat exchanger before it returns to the pump through the second branch.
- **Thermal conditioning circuit.** This invention describes a refrigerant circuit with a main loop containing a compression device, a condenser, an expansion device, and an evaporator. A bypass branch includes a second evaporator and a thermostatic expansion valve that varies the refrigerant flow area. A flow-restriction device limits that area to less than the valve’s maximum, helping regulate refrigerant flow through the bypass.
Career Highlights
El Chammas’s patent portfolio reflects work on vehicle thermal systems, including heat-transfer-fluid routing and refrigerant-flow control. These technologies are relevant to the thermal-conditioning challenges of hybrid and electric vehicles.
