Embodiment Construction

[0031] The invention relates to an evaporator 1, as schematically shown in Figure 9 shown in . The evaporator 1 shown has a heat transfer core 2 with a plurality of tubes 3 and a plurality of fins 4 . Tubes 3 and fins 4 are preferably arranged alternately here, but they can also be arranged in other arrangements.

[0032] The tubes 3 are flowed through by a first fluid 5 , wherein the tubes 3 and the fins 4 are flowed around by a second fluid 6 for heat transfer between the first fluid 5 and the second fluid 6 .

[0033] The evaporator 1 has at least one collecting tank 7 which is in fluid connection with the pipes 3 , wherein at least two collecting chambers 8 are formed by the at least one collecting tank 7 . it's here, Figure 9 The embodiment of the present invention has two collecting tanks 7 , wherein one of the two collecting tanks 7 is divided into at least two collecting chambers 8 by at least one inner partition wall, not shown. The other collecting box 7 can ha...

Abstract

The invention relates to an evaporator with a heat transfer core. The heat transfer core has 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.

Description

technical field [0001] The invention relates to an evaporator for a refrigerant cycle, in particular for a motor vehicle refrigerant cycle. Background technique [0002] Evaporators of air conditioning systems with a refrigerant circuit are usually designed such that the evaporator has two evaporator connecting lines, namely an injection line and a suction line. Here, the injection pipe is used to supply the refrigerant and the suction pipe is used to discharge the refrigerant. [0003] Here, an expansion valve is fixed on the evaporator in order to reduce the pressure of the injected refrigerant before the inlet of the evaporator. Accordingly, the expansion valve is mounted on the injection line and on the suction line and is at least fluidly connected to the injection line. Here, the mounting takes place at least via a carrier plate, which is fastened to the injection pipe and to the suction pipe. If the expansion valve is mounted on the injection line and optionally on...
