Heat exchanger with thermal inertia for a heat transfer fluid circuit, particularly of a motor vehicle A heat exchanger for a heat transfer fluid circuit comprising ducts for the circulation of the heat transfer fluid, which are inserted between an inlet and an outlet, is described. Cavities designed to contain a heat storage fluid adjacent to the cooling fluid circulation ducts and associated with heat-exchange surfaces, so that heat storage fluid is capable of exchanging heat with the air flow, if the circulation of the heat transfer fluid is stopped, are also described.

The invention relates to an air conditioning device for the passenger compartment of a vehicle, said device comprising a first closed loop (BF) which contains an evaporator (BF5), through which an air stream (F) may flow, and in which a first coolant may flow such as to transfer cold to said air stream in the evaporator. According to said invention, the device comprises a second closed loop (BS) in which a second coolant may flow between the evaporator (BF5) and a tank (BS2), such as to receive cold from the first coolant in the evaporator for storing the same in the tank and returning to the air stream in the evaporator, according to the cooling capacity, produced by the first loop and to the air conditioning needs.

A motor-vehicle heating and/or air conditioning device has a cold-air duct, a hot-air duct housing a heating radiator, a mixing chamber communicating with respective air outlets of the ducts and a mixing means. The mixing means has at least one flap of drum type which, in the “hot” position, closes off the outlet of the cold-air duct, and, in the “cold” position, closes off the outlet of the hot-air duct. The shutter wall of the flap includes at least one recess such that, when the flap is shifted from the “hot” position to the “cold” position, a cold airflow can pass through the recess so as to encounter a hot airflow.

The subject of the invention is a motor vehicle heating, ventilation and/or air conditioning installation (1). Said installation (1) comprises a unit (3) housing at least one blower (15) interposed between an upstream volume (16) and a downstream volume (17) which volumes are delimited by the unit (3). The upstream volume (16) houses a mixing chamber (18) provided with a mixing flap (20). The upstream volume (16) houses a filter (23). Said installation (1) is fitted with means (27, 20, 24, 25) for regenerating the filter (23). The means (27, 20, 24, 25, 14) for regenerating the filter (23) comprise an interstitial space (27) linking the upstream volume (16) and the downstream volume (17) which is created between the unit (3) and the blower (15).
摘要:
The engine cooling radiator and the evaporator of the air conditioning system for a vehicle are combined in a single triple heat exchanger, in which the refrigerant fluid and the engine coolant fluid flow respectively in two sets of flat pockets which are stacked alternately with gaps in which the air to be treated flows. A pocket of one set is directly juxtaposed to a pocket of the other set, to form a pair of pockets, between each gap and the next, to give direct heat transfer between the refrigerant and engine coolant fluids.

The invention relates to heating and/or air conditioning apparatus for the cabin of a motor vehicle, of a kind in which two separate fans deliver air into a common housing through which the air is passed to a heat exchanger. The object of the invention is to obtain even distribution of the air delivered through the heat exchanger, despite any differences in the flow rates of air delivered by one fan as compared with the other. The apparatus includes a housing having two inlet sections which are arranged facing each other and which are connected to the two respective fans for introducing the two air streams into the housing in parallel and opposed inlet directions. These directions are parallel to a base wall of the housing, and this base wall is provided with a separating bulkhead which projects from it into the interior of the housing. The bulkhead extends in a direction close to the inlet direction, which is substantially diagonal so as to define two chambers within the housing and extending over substantially the same width in the inlet direction. The two chambers exhaust into an outlet section which leads to the heat exchanger.

The invention relates to a diffusion device (1) for an automotive vehicle. The diffusion device (1) comprises a housing (2) with an ambient air inlet (3), a treated air outlet (3), a diffusion chamber (4) and an insert (7). The insert (7) is located inside the diffusion chamber (4) and contains at least one volatile agent (AV1). The insert (7) can rotate via an electric motor (12) for selectively diffusing or not the volatile agent (AV1). The diffusion device (1) also comprises a blower (13) fixed on the housing (2). The insert (7) comprises a member (15) which carries two cartridges (8, 9) containing volatile agent. The member (15) rotates with the insert (7) and can be axially displaced by extraction means. These extraction means expels the member (15) out of the housing (2) when the user pushes on the cap (14).
