A method for assembling a fuel cell humidifier can include steps of providing a first humidifier plate and a humidifier membrane. The first humidifier plate can have a first top plate surface. The humidifier membrane can have a bottom membrane surface. The bottom membrane surface of the humidifier membrane can be disposed on the first top plate surface of the first humidifier plate. The first humidifier plate can be partially melted. This can permit the first top plate surface of the first humidifier plate to permeate into the bottom membrane surface of the humidifier membrane. The first humidifier plate can be cooled, which can fuse the first top plate surface of the first humidifier plate with the bottom membrane surface of the humidifier membrane.

An outer finned tube includes a tube body, an outer wall of the tube body is provided with outer tins spirally arranged in an extension direction of the tube body; grid fins are arranged between two adjacent spiral parts of the outer fins correspondingly; two ends of each grid fin are connected to the two adjacent spiral parts of the corresponding outer fin respectively; a gap is kept between each grid fin and the outer wall of the tube body; and the plurality of grid fins are spaced in the extension direction of the tube body. An enhancing cavity is formed in an area defined by the outer wall of the tube body, inner walls of the grid fins and the outer tins in an encircling way, which can form a larger degree of superheat, provides a nucleation point for a boiling/condensation process and improves a heat exchange performance.

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.

Pierced thermal interface constructions including a thermal interface material (TIM) structure comprising: a TIM sheet comprising a plurality of piercings, where each of the plurality of piercings comprises a cavity and displaced material, and where the displaced material from each of the plurality of piercings protrudes away from the TIM sheet.
