Abstract
A liner tube for an inlet channel of a plate heat exchanger may include an open front side for supplying a refrigerant mass flow, an at least partially closed rear side, and at least two bag-like chambers running in a longitudinal direction of the liner tube. Each chamber may communicate with the open front side, and may have openings at chamber-dependent different positions for distributing the refrigerant mass flow in plate stacks of the plate heat exchanger.
Claims17
A liner tube for an inlet channel of a plate heat exchanger, comprising:
- an open front side for supplying a refrigerant mass flow;
- an at least partially closed rear side;
- and
- at least two bag-like chambers running in a longitudinal direction of the liner tube, each chamber communicating with the open front side and having openings at chamber-dependent different positions for distributing the refrigerant mass flow in plate stacks of the plate heat exchanger;
- wherein the openings are embodied in a slit-shaped manner;
- and
- wherein the at least two chambers are formed by secant partition walls running in the longitudinal direction and arranged parallel to one another.
A plate heat exchanger comprising:
- an inlet channel;
- a plurality of plate stacks;
- and
- a liner tube having:
- an open front side for supplying a refrigerant mass flow;
- an at least partially closed rear side;
- and
- at least two bag-like chambers running in a longitudinal direction of the liner tube, each chamber communicating with the open front side and having openings at chamber-dependent different positions for distributing the refrigerant mass flow in the plate stacks;
- wherein the liner tube is arranged in the inlet channel in such a way that the openings are each oriented in a respective one of the plate stacks, and the refrigerant mass flow is a two-phase mixture;
- and
- wherein the at least two chambers are formed by secant partition walls running in the longitudinal direction and arranged parallel to one another.

- wherein at least one of the chambers has at least one drainage opening arranged on the rear side for discharging oil;
- wherein the openings are embodied in a slit-shaped manner;
- and
- wherein the at least two chambers are formed by secant partition walls running in the longitudinal direction and arranged parallel to one another.
