Abstract: A two-phase heat exchanger is disclosed. The heat exchanger includes at least one inlet collector and at least one outlet collector, which are arranged spaced apart with respect to one another in a first direction. A matrix is arranged between and fluidly connected to the inlet collector and the outlet collector. In at least one of the inlet collector and the outlet collector, at least one aperture is arranged, which is spaced apart with respect to an associated collector opening in a second direction running transversely to the first direction. The at least one aperture has aperture openings, which are open in the second direction and through which a flow path of a temperature control medium leads.

Abstract: The present invention relates to a heat exchanger module having a collector and a heat exchanger. It is substantial for the invention that on a connecting flange of the collector at least one groove equipped for conducting refrigerant is provided. Further, the invention relates to a motor vehicle having at least one such heat exchanger module.

Abstract: An intermediate refrigerant store of a refrigerant system may include a storage container delimiting a refrigerant storage space, a first feed, and a second feed separate from the first feed. The first feed and the second feed may be fluidically connected with the refrigerant storage space for feeding of a refrigerant. At least one discharge may be fluidically connected to the refrigerant storage space and may be configured to discharge the refrigerant from the refrigerant storage space. At least one valve arrangement may be disposed in an associated feed of the first feed and the second feed via which the associated feed may be fluidically closable and openable.
