Title: DEVICE FOR DISTRIBUTING A REFRIGERANT FLUID INSIDE A COLLECTOR BOX OF A HEAT EXCHANGER
Abstract:
The invention concerns a device (18a) for distributing a refrigerant fluid (FR) configured to be housed inside a collector box (7) of a heat exchanger (5). The distribution device (18a) extends along a longitudinal direction (D2) and comprises at least one duct (14) extended along a longitudinal axis (A1). The duct (14) comprises, at a first of its longitudinal ends (15), an intake orifice (10) for admitting the refrigerant fluid (FR) into the duct (14) and is closed at a second longitudinal end (16). The duct (14) comprises, along at least one part of its length, at least one orifice (17) for discharging the refrigerant fluid (FR) from the duct (14). The distribution device (18a, 18b) comprises at least one mixer (19) surrounding the duct (14), at least in part, and which is configured to mix a liquid phase and a gas phase of the refrigerant fluid (FR) discharged from the duct (14).
