Abstract
A heat exchanger having a heat exchanger core which is configured as a plate stack has a flange plate including at least one upper partial plate facing the heat exchanger core and at least one lower partial plate facing away from the heat exchanger core. The flange plate can include a supercooling passage which is bounded by at least one partial plate in the stacking direction of the partial plates and which receives a flow of refrigerant during the operation of the heat exchanger. A high variability can be provided thanks to the compact and flexible design, by means of which the most diverse of requirements can be achieved with no major design changes.

1-4. (canceled)
A heat exchanger comprising:
- a heat exchanger core configured as a stack of plates, alternating ducts for a flow of refrigerant and a flow of a liquid coolant defined between adjacent ones of the plates;
- a flange plate joined to a lowermost plate of the stack of plates, the flange plate comprising an upper plate facing the heat exchanger core to which the lowermost plate of the stack of plates is joined, and a lower plate facing away from the heat exchanger core;
- and
- a supercooling passage for the flow of refrigerant arranged within the flange plate and bounded by at least one of the upper and lower plates of the flange plate, the supercooling passage extending directly below the heat exchanger core to allow for the transfer of heat between refrigerant passing through the supercooling passage and liquid coolant passing through that duct of the heat exchanger core bounded by said lowermost plate of the stack of plates, wherein the flange plate further comprises:
- a first refrigerant inlet, arranged in the upper plate within the connection region by which the heat exchanger core is joined to the flange plate;
- a first refrigerant outlet arranged outside of the connection region;
- a fluid transfer line extending between the first refrigerant inlet and the first refrigerant outlet;
- a second refrigerant inlet arranged outside of the connection region and fluidly connected to the supercooling passage;
- and a second refrigerant outlet arranged outside of the connection region and fluidly connected to the supercooling passage.
