CPC classification number: F25B41/062 , B60H1/00485 , B60H1/00907 , B60H2001/3286 , F25B2341/061 , F25B2341/0653 , F25B2500/18
Abstract: An expansion and isolation valve, specifically an electric expansion and isolation valve for operation with the coolant R744, featuring a valve body arranged in a valve body chamber, a seal seat, and a seal, which are arranged along an axial movement direction of the valve body in the expansion valve. The expansion valve is further designed such that in a closed state of the expansion valves, there is a pressure bypass to the valve body chamber, and preferentially, that a valve body diameter at the positions of the seal seat and the seal corresponds with the respective seal diameters.

Abstract: A heat exchanger with at least one plate includes main dimples between which secondary dimples are formed which are flatter and/or smaller with respect to their dimensions as seen in a plan view. A depth of the secondary dimples may be at most 0.5 times a channel height and/or at most 0.5 times the depth of the main dimples.

Abstract: In a heat exchanger for use with a refrigerant under a pressure of 140 bar or more, channels for the refrigerant and another fluid are formed directly two or more plates, and at least one manifold for the refrigerant is formed outside the plates, which is connected to the channels by openings.
