Abstract: An evaporator with a heat transfer core having a number of pipes and fins, wherein a first fluid can flow through the pipes and a second fluid can flow around the pipes and the fins for heat transfer between the first fluid and the second fluid, with at least one collecting tank which is in fluid connection with the pipes, wherein at least two collecting chambers are formed by means of the at least one collecting tank, wherein one of the collecting chambers is equipped with a first fluid connection pipe which serves as an injection line for supplying the first fluid and the other collecting chamber is equipped with a second fluid connection pipe which serves as a suction line for discharging the first fluid, wherein for mounting an expansion valve on at least one of the fluid connection pipes a retaining element is fastened to at least one of the fluid connection pipes.

Abstract: An installation frame for a heat exchanger, in particular for a heat exchanger in particular for installation in an air-conditioning system for motor vehicles, having frame elements that encompass the heat exchanger at the short sides thereof arranged parallel to the air flow direction, whereby the frame elements are connected to one another, and whereby the installation frame is in the form of a sealing element.

Abstract: An air vent for a vehicle interior ventilation system including a diffuse air flow duct with a diffuse outlet opening for discharging the air as a diffuse or swirling jet, a movable connecting sleeve with an inflow opening and an outflow opening as a spot outlet opening, which forms a spot air flow duct at a spot outlet opening. Through movement of the connecting sleeve, different discharge directions of the spot jet from the spot outlet opening can be adjusted. The air discharged through the connecting sleeve is redirectable substantially completely in different discharge directions with pivoting of the connecting sleeve. The connecting sleeve has a greater cross-sectional area at the inflow opening than at the outflow opening and at least one air guiding wall is formed in the connecting sleeve.
