Description

Assembly comprising a heat exchanger Technical Field The present invention relates to an assembly comprising a heat exchanger, in particular for a vehicle. Background The vehicle may be a land vehicle, an offshore vehicle or an aerial vehicle. In general, there is a desire to reduce the space occupied by components in a vehicle. This is a significant challenge. In the case of a vehicle heat pump, one approach is to make all its components, in particular the refrigerant circuit and the heat transfer fluid circuit, compact. There is also a need to improve the performance of various cooling functions on motor vehicles. The present invention is particularly directed to achieving such an objective. Disclosure of Invention The invention therefore relates to an assembly, in particular for a vehicle, comprising: A heat exchanger configured to allow heat exchange between a flow of a first heat transfer fluid, in particular water-based, inside the heat exchanger on the one hand and a flow of a second heat transfer fluid, in particular a refrigerant or a dielectric fluid, inside the heat exchanger on the other hand, In particular a support arranged to carry at least one component having a fluid function, in particular a plurality of components having a fluid function, -A container arranged to receive the heat exchanger, the container being configured such that, when the heat exchanger is placed in the container, a fluid path for a third heat transfer fluid is formed between a side wall of the container and a peripheral wall of the heat exchanger, the fluid path being configured to be fluidly connected to an external cooling circuit for cooling at least one auxiliary module, in particular an auxiliary electronic module, the operation of which is temperature sensitive. By means of the invention, the auxiliary module or modules can be cooled using a heat exchanger dedicated to, for example, a vehicle air conditioner (e.g. forming part of a heat pump). The assistance module is for example an electronic module forming part of a driver assistance system or an ADAS. The invention is particularly advantageous in that it provides synergy between the various cooling functions by using the same heat exchanger for the various functions. The present invention enables various cooling functions to be concentrated around the heat exchanger. In particular, the invention recommends the use of a heat exchanger, in particular of the "cooler" type, for exchanging heat with a third fluid circulating in a fluid path around the heat exchanger. This heat exchange pattern of the third fluid may be sufficient when the third fluid in the external cooling circuit is used for cooling an auxiliary module requiring a relatively low cooling power, e.g. a cooling power of less than 5 kW (kw), e.g. between 2 kW and 3 kW. The invention makes it possible to obtain improved performance when the cooling demand is relatively low, in particular compared to the cooling power obtained in the heat exchanger between the first heat transfer fluid and the second heat transfer fluid. For example, A Driver Assistance System (ADAS) requires only about 1 or 2 kW cooling power. The external cooling circuit may be separate from the flow of the first heat transfer fluid within the heat exchanger. Thus, for the first heat transfer fluid circulating in the heat exchanger, it is possible to have a flow value and a temperature value that are different from those of the third fluid circulating in the external cooling circuit. For example, where the first heat transfer fluid is used to cool a vehicle battery, the first heat transfer fluid circulated in the heat exchanger may have a temperature of about 25 degrees and a flow rate of about 1000 liters per hour. The third fluid circulating in the external cooling circuit may itself have a temperature of about 65 degrees and a flow rate of about 150 liters per hour in order to cool, for example, A Driver Assistance System (ADAS). Integrating this fluid path around the heat exchanger makes it possible to manage the cooling of the auxiliary electronic module without reducing the cooling capacity of the heat exchanger or "cooler". Another advantage that the invention may provide is the compactness of the assembly around the heat exchanger, since the container and the support carrying the component or components with fluid function may be manufactured as a single one-piece component. Thus, the present invention allows for greater integration of the various elements of the assembly. According to one aspect of the invention, the container and the support are manufactured as a single piece. According to one aspect of the invention, the container and the support are formed as a single one-piece part, in particular obtained by moulding, in particular from a plastic material. As a variant, the container and the support are produced as separate parts and then assembled to each other. In particular, the container and the support may be detach
