Abstract: A radiator arrangement for a vehicle, including a radiator and an air guiding element for guiding an airflow towards the radiator. The air guiding element has an inlet for letting in the airflow and an outlet facing the radiator. The air guiding element includes a plurality of louvers which are configured to prevent stones of a predetermined size to hit the radiator. The louvers are fixed in position relative to a housing of the air guiding element. The housing is configured to guide the airflow towards the outlet. The outlet has a cross-sectional area at least encompassing an area of a front face of the radiator, and the front face of the radiator is exposed to the airflow.

Abstract: A module assembly for a refrigerant circuit of a motor vehicle. The module assembly includes an inner heat exchanger and a heat exchanger through which a coolant can flow. The inner heat exchanger is designed to transfer heat from a high-pressure side of the inner heat exchanger to a low-pressure side of the inner heat exchanger. The heat is introducible into a refrigerant compressible by the compressor by operating a compressor of the refrigerant circuit. The heat exchanger is subjected to refrigerant that can be supplied to the heat exchanger from the high-pressure side of the inner heat exchanger and can be expanded by an expansion device of the module assembly. The module assembly is formed separately from an evaporator of the refrigerant circuit and/or separately from a condenser of the refrigerant circuit. and includes a support device separate from the heat exchanger, on which the heat exchanger is held.
