摘要： There is a need for better cooling solutions for the ever-increasing thermal density of computing systems. This is solved by providing a radiator (100) for a liquid cooling system for cooling a computing unit, the radiator comprising:—a first manifold (101) and a second manifold (102) having among them two liquid openings (103, 104) for connecting the radiator in a liquid loop, —channels (110) extending between the first manifold (101) and the second manifold (102) and providing parallel liquid paths between the manifolds (101, 102), —fin layers (130) sandwiched between sets of neighbouring channels (110) and extending between the first manifold (101) and the second manifold (102), —fastening means (120) for attaching a fan (10) to the radiator (100) in a predetermined position, determining a ring-shaped high-pressure zone (142) corresponding to an outer area of a fan radius (122) of an attached fan, where—at least one fin layer has a low-density section placed away from the high-pressure zone, and a high-density section being located in the high-pressure zone and having a higher fin density than the low-density section, —the density of the group of fin layers thereby varies both along the channels but also transverse of each channel, resulting in two-dimensional density variations across the radiator surface, sections of fins to be positioned in front of the ring-shaped high-pressure zone has a higher density than the section of fins away from the ring-shaped high-pressure zone.

摘要： A tube for use in a heat exchanger includes an upper portion, a base portion spaced from the upper portion, and a partitioning wall depending from the upper portion. The partitioning wall is bent away and spaced from the base portion in a first section of the tube to form a single flow channel within the tube along the first section. The partitioning wall contacts the base portion in a second section of the tube to form a partition separating a first flow channel from a second flow channel along the second section. The first section of the tube is configured for reception into an opening of a header tank of the heat exchanger.

摘要： [Purpose] To provide is a method capable of producing a heat-dissipating unit easily and at low cost.
[Solution] The method of producing a heat-dissipating unit 12 includes: inserting pins 17 punched out of a second plate member 22 for pins into a plurality of through-holes 16 formed in a first plate member 20 for a substrate. In the first plate member 20, a plurality of substrate forming portions 25 is provided side by side in the longitudinal direction of the first plate member 20. In the second plate member 22, a plurality of pin punch-out portions 26 is provided side by side in the longitudinal direction of the second plate member 22. The method includes: a step A of forming the through-holes 16 in the substrate forming portion 25 of the first plate member 20; a step B of subjecting the pin punch-out portion 26 of the second plate member 22 to a half-punch out process to form half-punched-out pin forming portions 27 protruding from one surface side of the second plate member 22; a step C of forming the pins 17 by punching out the pin forming portions 27 from the second plate member 22 and simultaneously inserting the pins 17 into the through-holes 16 in the first plate member 20; and a step D of forming a substrate by cutting the substrate forming portion 25 with the pins 17 inserted in the through-holes 16 from the first plate member 20.-

摘要： 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.

摘要： A manufacturing method and structure of heat pipe with adjustable working temperature range are provided. The heat pipe includes a tube, a capillary structure and a working liquid. The tube includes a passage having a length direction and a diameter direction. Besides, a part of the tube has a pressed deformation zone in the pipe diameter direction, and the pressed cross-sectional area of the deformation zone in the diameter direction is reduced by a reduction ratio with respect to an original cross-sectional area before pressing, so that the deformation zone has a higher fluid resistance. Thereby, the heat pipe can be operated under a certain working temperature range, and the working object can achieve the working efficiency.
