Description

Thermal conditioning system comprising two plates forming two fluid circuits Technical Field The present invention relates to a thermal conditioning system for heating and/or cooling electrical and/or electronic components of an electric or hybrid motor vehicle, and preferably for heating and/or cooling the passenger compartment of said vehicle. The invention also relates to a method for assembling the thermal conditioning system. The present invention relates to the field of thermal conditioning systems. These systems can be provided in particular on motor vehicles. Such a system allows for thermal conditioning of various components of the vehicle, such as the passenger compartment or the electric energy storage battery in the case of an electric vehicle. Heat exchange is primarily managed by evaporation and condensation of refrigerant within the various heat exchangers, allowing for heating or cooling of the various components. Background Thermal conditioning systems typically utilize a refrigerant circuit and a heat transfer fluid circuit that exchanges heat with the refrigerant. Such a system is therefore referred to as indirect. The refrigerant circuit is formed such that the refrigerant rejects heat to the heat transfer fluid in the first heat exchanger. The heat released to the heat transfer fluid may then be dissipated into the air flow for the passenger compartment to heat the passenger compartment. The heat transfer fluid circuit also makes it possible to cool a heat-radiating element of the drive train of the vehicle, such as the electric drive motor of the vehicle or the power electronics controlling the electric motor. To this end, another heat exchanger makes it possible to exchange heat between the heat transfer fluid and the refrigerant in order to cool the heat transfer fluid. Therefore, it is desirable to arrange a thermal conditioning system that is capable of providing various modes of cooling and/or heating various elements of the battery or the drive train of the vehicle as compactly as possible. The thermal conditioning system comprises, inter alia, thermal management components, such as pumps, valves, heat exchangers, in particular condenser and/or plate cooler heat exchangers, accumulators or desiccant tanks, and components for temperature conditioning, in particular temperature and/or pressure sensors. Also provided are components such as pipes that direct fluids and fluidly connect thermal management components to one another. The development of electric vehicles has increased the need for an optimized thermal conditioning system with a simplified and economical manufacturing method, while creating a need for a system with a reduced footprint. Optimal management of space under the hood or more generally in vehicles remains necessary, including for electric vehicles where new components (as compared to conventional automobiles) are necessary. There is also a great advantage in reducing the number of these components or their associated connections. The present invention aims mainly at proposing a solution to improve this situation. Disclosure of Invention The present invention therefore relates to a thermal conditioning system for heating and/or cooling electric and/or electronic components and/or passenger compartments of an electric or hybrid motor vehicle, using two plates for supporting said components and a single intermediate plate for forming a fluid circulation channel, said support plates being configured such that their association with the intermediate plate/their fastening with the intermediate plate forms a flat closing portion for closing/defining each of said channels. The present invention therefore relates to a thermal conditioning system for heating and/or cooling electrical and/or electronic components, in particular batteries, of an electric or hybrid motor vehicle, and preferably for heating and/or cooling the passenger compartment of said vehicle, comprising: -a heat transfer fluid circuit for heating and/or cooling electrical and/or electronic components, and preferably for heating and/or cooling a passenger compartment of a vehicle, said circuit comprising a first plate extending along a plane P1, said first plate forming a first channel by a protrusion with respect to said plane P1, said first channel defining a collector for heat transfer fluid; -a refrigerant circuit comprising: an o-condenser for the heat-transfer fluid, An o-type compressor, which is provided with a compressor, A first evaporator, preferably for cooling the passenger compartment of the vehicle, The refrigerant circuit comprises a second plate extending along the plane P2, which second plate forms a second channel by means of a projection with respect to the plane P2, which second channel defines a collector for the refrigerant. The thermal conditioning system according to the invention is characterized in that it further comprises an intermediate plate located between the first plate an
