  • Patent number: 10254022
    Abstract: A condenser for an air conditioning circuit is disclosed. The condenser has a housing which is connected to a refrigerating fluid reserve by a flange having cylinder shaped tubes, the housing receiving a first heat exchange portion between the refrigerating fluid and a cooling liquid, the first portion being configured to convey the refrigerating fluid to the refrigerating fluid reserve, and a second heat exchange portion which produces a heat exchange complement between the refrigerating fluid and the cooling liquid at the outlet of the refrigerating fluid reserve.

  • Patent number: 10197341
    Abstract: The invention relates to a heat exchanger (1), especially an exchanger for the air-conditioning system of a vehicle, allowing heat exchange between first (F1) and second (F2) fluids, said exchanger (1) comprising a plurality of tubes (3) for the circulation of the first fluid (F1), which are stacked one on top of the other, and at least one collector (5) comprising a collector plate (7), said collector plate (7) comprising openings (13) for inserting the ends (3a) of tubes (3), characterized in that said ends (3a) of said (3) are assembled at least two by two in the insertion openings of the collector plate (7).

  • Patent number: 10132573
    Abstract: The invention relates to a heat exchanger, said exchanger including a bundle of tubes (2), which enables an exchange of heat between a refrigerant circulating in said tubes (2) and an external airflow, and a first collector (4), said exchanger being configured so as to establish the serial circulation of the refrigerant among a first portion of said tubes (2) leading into a first portion (4a) of said first collector, said first collector (4), and a second portion of said tubes (2) leading into a second portion (4b) of said first collector (4). According to the invention, said first collector (4) includes a partition (12) configured to disrupt the circulation of the fluid between the first and second portions of said tubes (2). The invention is specifically for electric and/or hybrid motor vehicles.

  • Patent number: 9834061
    Abstract: 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.

  • Publication number: 20150096726
    Abstract: A spacer (7) for an air heater comprises a predefined number of planar walls (13; 113) that are substantially parallel and are connected two-by-two by folds (15). The planar walls (13; 113) include a plurality of louvers (171, 172) that are substantially inclined relative to the general plane (P) defined by the planar wall (13; 113). The planar wall (13; 113) further includes at least one strap (19; 1191, 1192, 1193, 1194) having longitudinal sides (21) that extend parallel to the planar wall (13; 113) and lateral sides (23) that are linked to the planar wall (13; 113) by means of at least one connecting rail (24). An air heater comprises a heat exchange bundle comprising a stack of parallel tubes (5) for the circulation of the fluid, the tubes having the width (l1) of a tube, and a plurality of such spacers (7) disposed respectively between two tubes (5).
