Heat exchanger

摘要

Disclosed herein is a plate-type heat exchanger or chiller, with multiple stacking plates stacked one on top of the other such that a first fluid duct for a first fluid and a second fluid duct for a second fluid are formed between the stacking plates. A first inlet and outlet opening for conducting in and discharging the first fluid, and a second inlet and outlet opening for conducting in and discharging the second fluid is provided. The first inlet or outlet opening is formed by an immersion pipe and the first fluid can be conducted into the first fluid duct through the immersion pipe, such that the first inlet and outlet openings are formed on the same side of the heat exchanger.

主权项

1. A heat exchanger or chiller of plate-type construction, comprising:
a multiplicity of stacking plates stacked one on top of the other, such that between the stacking plates there is formed at least a portion of a first fluid duct for a first fluid and at least a portion of a second fluid duct for a second fluid; the stacking plates have first apertures forming an additional portion of the first fluid duct for the supply and discharge of the first fluid; the stacking plates have second apertures forming an additional portion of the second fluid duct for the supply and discharge of the second fluid; at least one diverting device that closes off at least one first aperture such that the first fluid is conducted in opposite directions through the heat exchanger in a meandering fashion through at least two portions of the first fluid duct between the stacking plates; a first inlet and outlet opening for conducting the first fluid in and out; a second inlet and outlet opening for conducting the second fluid in and out; wherein the first inlet or outlet opening is formed by an immersion tube, and the first fluid can be conducted into or out of the first fluid duct through the immersion tube such that the first inlet and outlet openings are formed on the same side of the heat exchanger; wherein the immersion tube has at least one flow opening for conducting the first fluid into or out of the first fluid duct at the first apertures and the at least one flow opening is formed radially and/or axially with respect to a longitudinal axis of the immersion tube; wherein the heat exchanger is in the form of an evaporator with a thermal expansion valve, and the first fluid is a refrigerant and the second fluid is a coolant.
