The invention relates to a heat-exchanger for an air-conditioning circuit that includes a first pipe () defining a path for a flow of fluid, the first pipe being spirally wound about a so-called exchanger axis (A). According to the invention, the heat exchanger () further includes at least one second pipe () defining a path for a flow of a second fluid, said second pipe being provided against a surface of the first pipe () and spirally wound together with said first pipe () about said axis (A). The invention can be used in air-conditioning circuits operating with a super-critical coolant, in particular carbon dioxide (CO2).

Heat exchanger and integrated air-conditioning assembly including such exchanger

A device () is for connection between a component () of an air-conditioning loop () and a heat exchanger (), including at least one channel () through which a fluid () can flow. The device includes an inner part () having at least one collar () at least partially defining a channel () and capable of engaging with an opening () of the exchanger (), and an outer part () mounted against the inner part (), having at least one end piece () at least partially defining the channel () and capable of engaging with an opening of the component (). The invention also relates to a heat exchanger provided with the connection device ().

Device for connection between a component of an air-conditioning loop and a heat exchanger

The invention relates to a heat exchanger for exchanging heat between a first (HP) and a second (BP) fluids. According to the invention, said exchanger comprises a plurality of modules () respectively including an upper plate () and a lower plate () assembled so as to define, between said plates (), an inner cavity () forming a first circulating channel for the first fluid (HP), wherein said exchanger further comprises a housing () in which said modules () are assembled in order to form said exchanger while defining spaces () between said modules, said spaces forming second circulation channels for the second fluid (BP).

Heat exchanger

The invention relates to a combined device () comprising a casing () made of an upper wall (), a down wall () and a lateral wall (). The said casing () accommodates an internal heat exchanger (), a separation area () and an accumulation area (). The casing () accommodates an internal component () which is made of:
