Embodiment Construction

[0033] The following examples are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference numeral refers to the same embodiment, or that a feature applies to only a single embodiment. Individual features of different embodiments can also be combined and / or interchanged to create other embodiments.

[0034] In this specification, certain elements or parameters may be provided with serial numbers, such as the first element or the second element, the first parameter and the second parameter, or the first criterion and the second criterion, etc. In this case, these sequential numbers are only used to distinguish and name similar but not identical elements, parameters or criteria. This sequential numbering does not imply any priority of one element, parameter or criterion over another element, parameter or criterion, and such numbering may be readily interchanged without departing from the scope of the present invent...

Abstract

The present invention relates to a circuit (1) for the thermal management of a hybrid or electric vehicle, the thermal management circuit (1) comprising a first reversible air conditioning loop (A) through which a refrigerant circulates and which comprises a two-fluid heat exchanger (19) arranged jointly on a second loop (B) in which a heat-transfer fluid circulates, the second, heat-transfer fluid, circulation loop (B) comprising: a first circulation leg (B1) comprising, in the direction in which the heat-transfer fluid circulates, a first pump (49), a first radiator (45) placed in an internal air flow (100), and a batteries heat exchanger (47), a second circulation leg (B2) connected in parallel to the second radiator (45) and comprising a second pump (41) and a device (43) for electrically heating the heat-transfer fluid, and a third circulation leg (B3) connected in parallel to the first pump (49) and to the batteries heat exchanger (47), the third circulation leg (B3) comprising the two-fluid heat exchanger (19).

Description

technical field [0001] The present invention relates to the field of motor vehicles, and more particularly to thermal management circuits for hybrid or electric vehicles. Background technique [0002] In electric and hybrid vehicles, thermal management of the passenger compartment is usually performed by a reversible air conditioning loop. Reversible means that the air conditioning loop can operate in cooling mode to cool the air sent to the passenger compartment, and in heat pump mode to heat the air sent to the passenger compartment. The reversible air conditioning loop may also include a spur in order to manage the temperature of the battery of the electric or hybrid vehicle. Thus, the battery can be heated or cooled by a reversible air conditioning loop. However, the temperature of the battery cannot be managed, at least in part, without the use of a reversible air conditioning loop. For example, when there is no need to heat or cool the passenger compartment, it is t...
