Embodiment Construction

[0052] FIG. 1 shows an air conditioning device of a motor vehicle. The unit generally comprises a refrigerant circuit BF in which the fluid flows sequentially through a compressor BF1, a condenser BF2, a tank or "bottle" BF3, a pressure reducer BF4 and an evaporator BF5 before being returned to the compressor. The device also includes a heating circuit BC. In this circuit BC the cooling fluid of the engine M of the vehicle flows under the action of the pump BC1 driven by the engine M. Circuit BC also includes a radiator BC2 and a solenoid valve BC3 for controlling the flow of fluid in this radiator. The air flow indicated by arrow F passes sequentially through evaporator BF5 and radiator BC2 to reach the desired temperature before it is introduced into the passenger compartment of the vehicle.

[0053] According to one embodiment of the invention, the evaporator BF5 is also part of the circuit BS, which also includes the electric circulation pump BS1 and the fluid storage ta...

Abstract

The invention relates to a heat exchanger, in particular for an air conditioning, ventilation and / or heating system of a motor vehicle. The heat exchanger comprises a plurality of stacked modules (100). The modules define two sets of distinct channels for the circulation of the first heat transfer fluid and the second heat transfer fluid and are connected to inlet and outlet conduits (101, 102, 104, 105) for the two heat transfer fluids.

Description

technical field [0001] The present invention relates to a heat exchanger. The heat exchanger is suitable as part of a heating, ventilation and / or air conditioning system, in particular of a motor vehicle. The heat exchanger includes a plurality of modules stacked in a first direction. The module is connected to inlet and outlet pipes for a first fluid and is adapted to circulate said first fluid. Background technique [0002] In the particular case of a motor vehicle, the heat exchanger may be, for example, an air-conditioning evaporator delivering refrigerant to cool the air flow and generate chilled air for the passenger compartment of the vehicle. The heat exchanger may also be a radiator that delivers hot fluid to heat the air flow and generate hot air that is sent to the passenger compartment. This thermal fluid is usually the cooling fluid of the vehicle engine. [0003] In a traditional air conditioning circuit, the refrigerant passes through the compressor, conde...
