Refrigeration Device With A Heat Exchanger

Abstract

A refrigeration device has a refrigeration device container, a door for closing an opening of the refrigeration device container, and a coolant circuit arrangement. The coolant circuit arrangement includes a first heat exchanger, a second heat exchanger, and a heating section for heating the opening region of the refrigeration device container. The first heat exchanger and the second heat exchanger include a multi-port extruded fluid line and are designed to discharge heat from the coolant circuit arrangement. The multiport extruded fluid line is thermally coupled to the heating section, and the heating section is arranged between the first heat exchanger and the second heat exchanger and is configured to dispense heat from the coolant circuit arrangement to the opening region of the refrigeration device container.
