L'invention concerne un générateur de froid, comportant un circuit de réfrigération. Selon l'invention, le générateur de froid comporte une unité formant échangeur de chaleur, dans laquelle un échangeur de chaleur dissipant la chaleur et un échangeur de chaleur absorbant la chaleur sont intégrés, l'unité échangeur de chaleur comportant une pile de couches de trajets d'écoulement à structure empilée. Selon l'invention, pour former l'échangeur de chaleur dissipant la chaleur, au moins un trajet d'écoulement de réfrigérant dissipant la chaleur et au moins un deuxième trajet d'écoulement de transport de chaleur absorbant la chaleur sont situés dans la pile de couches de trajets d'écoulement. Selon l'invention, le deuxième trajet d'écoulement de transport de chaleur peut être traversé ou est traversé par un deuxième milieu de transport de chaleur guidé dans un deuxième circuit de transport de chaleur. Selon l'invention, pour former l'échangeur de chaleur absorbant la chaleur, au moins un trajet d'écoulement de réfrigérant absorbant la chaleur et au moins un premier trajet d'écoulement de transport de chaleur dissipant la chaleur sont situés dans la pile de couches de trajets d'écoulement. Selon l'invention, le premier trajet d'écoulement de transport de chaleur peut être traversé ou est traversé par un premier milieu de transport de chaleur guidé dans un premier circuit de transport de chaleur.
