A method for controlling a thermal conditioning system is disclosed. The thermal conditioning system includes a refrigerant unit configured to circulate a refrigerant. The refrigerant circuit includes a main loop and a first bypass branch. The main loop includes a compression device, a first heat exchanger configured to exchange heat with a first heat transfer fluid, a first expansion device, and a first evaporator configured to exchange heat with an element of a powertrain of a motor vehicle via a second heat transfer fluid. The method includes determining a pressure of the refrigerant at the outlet of the first evaporator and controlling, depending on the determined pressure, at least one parameter so that the pressure of the refrigerant at the outlet of the first evaporator is below a predetermined pressure threshold.

Thermal conditioning system for a motor vehicle

The invention relates to a heat exchanger, said exchanger including a bundle of tubes (), which enables an exchange of heat between a refrigerant circulating in said tubes () and an external airflow, and a first collector (), said exchanger being configured so as to establish the serial circulation of the refrigerant among a first portion of said tubes () leading into a first portion () of said first collector, said first collector (), and a second portion of said tubes () leading into a second portion () of said first collector (). According to the invention, said first collector () includes a partition () configured to disrupt the circulation of the fluid between the first and second portions of said tubes (). The invention is specifically for electric and/or hybrid motor vehicles.

Heat exchanger, in particular for a vehicle

The invention relates to an assembly including a heat exchanger and a mounting on which the heat exchanger is mounted. The heat exchanger including a first channel for circulating a coolant supplied by a first collector provided with a first pipe in which the coolant can circulate. The heat exchanger also including a second channel for circulating the coolant supplied by a second collector provided with a second pipe in which the coolant can circulate. The first and second channels define a heat-exchange surface that extends in a substantially vertical plane. The first pipe is located in a lower half of the first collector along a first axis parallel to the plane of the heat-exchange surface, with the second pipe located above the first pipe along the first axis. The invention further relates to an air-conditioning loop including the above-described assembly.
