Problems solved by technology

[0009] However, this type of heat exchanger is not optimized for "heating" mode
The result of this lack of optimization is that, for a heat exchanger, the entire surface for exchange with the air flow is used for heat exchange in "cooling" mode, but almost 30% of this surface is not used for "heating" " mode
Moreover, internal pressure losses are not suitable for the mode of operation in "heating" mode, these pressure losses involve mechanical forces that are too great for the compressor

Embodiment Construction

[0031] figure 1 The air conditioning loop 1 of a vehicle according to the invention is shown operating in cooling mode. Such a loop 1 comprises conduits 10 defining a circuit within which a coolant fluid, also referred to as refrigerant fluid, circulates. The circuit 1 comprises a compressor 2, in particular an electric compressor, whose function is to circulate a coolant fluid in the circuit. The compressor 2 compresses and raises the temperature of the coolant fluid, which is then in gaseous form.

[0032] The outlet 3 of the compressor is connected to the inlet 6 of the first heat exchanger 5 . Such a heat exchanger 5 is an interior exchanger in the sense that the first heat exchanger 5 changes the temperature of the air flow 31 sent into the passenger compartment of the vehicle. In cooling mode, the first exchanger 5 does not exchange heat with other fluids and is only used as a conduit for circulating coolant fluid. It is thus isolated from the air flow 31 by means of...

Abstract

The invention relates to an assembly including a heat exchanger (12) and a mounting (70) on which said exchanger (12) is mounted, said exchanger (12) including a first channel (52) for circulating a coolant supplied by a first collector (50) provided with a first pipe (51) in which the coolant can circulate, and a second channel (54) for circulating the coolant supplied by a second collector (55)provided with a second pipe (56) in which the coolant can circulate, the first and second channels (52, 54) defining a heat-exchange surface (58) that extends in a substantially vertical plane. According to the invention, the first pipe (51) is located in the lower half of the first collector (50) along a first axis (80) parallel to the plane of the heat-exchange surface (58), the second pipe (56)being located above the first pipe (51) along the first axis (80). The invention further relates to an air-conditioning loop including the above-described assembly.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201380010809.6, the application date is January 29, 2013, and the invention title is "assembly including a heat exchanger and a mounting part on which the exchanger is installed". technical field [0002] The invention relates to the field of heat exchangers, for example suitable for operation by reversible air conditioning circuits, in particular for heating or cooling the passenger compartment of a vehicle. Background technique [0003] In vehicles comprising a combustion engine, a comfortable heat is ensured by using the heat of the engine for heating needs on the one hand and by an air conditioning system (operated by a mechanical compressor) for cooling needs on the other hand. [0004] With electric vehicles, on the other hand, it is not feasible to use the heat released by the heat engine, and the only available source of energy within the vehicle is elec...
