The invention relates to a heat exchanger plate (10) of a heat exchanger, the heat exchanger plate (10) comprising two faces (12, 13) extending between two lateral edges and two longitudinal edges (15) of said heat exchanger plate (10). The heat exchanger plate (10) comprises at least an opening (16) extending from a first face (12) to a second face (13) of the heat exchanger plate (10). The opening (16) is delimited by a collar (17) that is arranged around the opening (16). The heat exchanger plate (10) comprises at least a dimple (18) protruding above at least one of the faces (12, 13). Said dimple (18) comprises at least a flat area (19) and a sloped area (20), said sloped area (20) being interposed between the collar (17) and the flat area (19).

In a heat exchanger, each of a plurality of heat exchange members includes: a flat pipe; and a heat transfer plate integrated with the flat pipe along a longitudinal direction of the flat pipe. A width direction of each of the flat pipes intersects with a direction in which the plurality of heat exchange members are arranged side by side. Each of the heat transfer plates includes an extending portion extending outward in the width direction of each of the flat pipes from at least one of one end of a corresponding one of the flat pipes in the width direction and another end of the corresponding one of the flat pipes in the width direction. Each of the flat pipes has one or more flat pipe bent portions, each forming a groove extending along the longitudinal direction of the flat pipes.

The present disclosure provides a liquid-cooling type double-sided cooler, including a first cooling portion and a second cooling portion. In the liquid-cooling type double-sided cooler, another end of the first cooling portion is formed with a first communication hole that is configured to penetrate the first cooling liquid path and an outside of the first cooling portion, another end of the second cooling portion is formed with a second communication hole that is configured to penetrate the second cooling liquid path and an outside of the second cooling portion; and the first cooling portion and the second cooling portion are positioned such that the first communication hole and the second communication hole face each other, and the first cooling liquid path and the second cooling liquid path are connected with each other.

A water block assembly includes first and second water block units having respective first and second fluid conduits. The second water block unit is stacked on the first water block unit. The second fluid conduit operates either in parallel with the first fluid conduit or fluidly independent therefrom, such that cooled fluid is fed to the first and second fluid conduits. The first water block unit includes a first base portion and a first cover portion disposed on and affixed to the first base portion. The first cover portion defines a first fluid inlet and a first fluid outlet of the first fluid conduit. The second water block unit includes a second base portion and a second cover portion disposed on and affixed to the second base portion. The second cover portion defines a second fluid inlet and a second fluid outlet of the second fluid conduit.

The present disclosure is directed to devices, systems, and products for attracting, capturing and converting atmospheric water vapor into useful liquid water utilizing the thermal dynamic processes of deposition, phase change states and fusion.
