    Abstract: An adiabatic cooling system including a controller is operable to determine a time period between a first cycle in a recovery mode and a second cycle in the recovery mode. If the time period is less than a first preset time period, then there is a first time lapse before the controller enters the fluid supply mode, and if the time period is greater than a second preset time period, then there is a second time lapse before the controller enters the fluid supply mode, and the first time lapse is greater than the second time lapse.

    Abstract: A plate heat exchanger includes a stack of plate pairs with gaps between adjacent pairs, arranged to provide flow paths for a first fluid to pass through inner volumes of the plate pairs while simultaneously allowing a second fluid to flow over the outer surfaces of the plate pairs. At least one cylindrical fluid manifold for the first fluid extends through the plate pairs. A non-planar cap is arranged at one end of the plate heat exchanger to close off the cylindrical fluid manifold. A reinforcement plate is arranged at that end between the non-planar cap and an end plate of the plate heat exchanger. The position of the non-planar cap relative to a central axis of the cylindrical fluid manifold is maintained in order to prevent failure of the plate heat exchanger due to internal pressurization.

    Abstract: An air fin for a heat exchanger has air channels defined by corrugations, the corrugations having generally planar flanks joined by alternating crests and troughs. Perforations extend through portions of at least some of the flanks and are aligned within two spaced apart planes. A rectangular aperture extends through at least two consecutive ones of the corrugations, and is bounded by the two planes. A method of making the air fin includes forming perforations into a continuous strip of metal sheet at regular intervals, corrugating the strip to form crests and troughs between the perforations, and punching out a portion of the strip at regular intervals. The punching out includes shearing webs between the perforations, and results in the formation of the rectangular aperture.
