摘要： Dehumidifying cooling apparatus and method are provided for an electronics rack. The apparatus includes an air-to-liquid heat exchanger disposed at an air inlet or outlet side of the rack, wherein air flows through the rack from the air inlet to the air outlet side. The heat exchanger is positioned for air passing through the electronics rack to pass across the heat exchanger, and is in fluid communication with a coolant loop for passing coolant therethrough at a temperature below a dew point temperature of the air passing across the heat exchanger so that air passing across the heat exchanger is dehumidified and cooled. A condensate collector, disposed below the heat exchanger, collects liquid condensate from the dehumidifying of air passing through the electronics rack, wherein the heat exchanger includes a plurality of sloped surfaces configured to facilitate drainage of liquid condensate from the heat exchanger to the condensate collector.

摘要： The current invention provides a tube-grasping body for grasping an insert tube in a heat exchanger, and heat exchanger production methods and apparatuses utilizing the tube-grasping body, wherein said tube-grasping body enables to enlarge and connect an insert tube to a heat radiating fin for producing a heat exchanger, still keeping the total length of insert tubes at an almost same level even after the enlargement; and said tube-grasping body is connected at its exterior to the guide-pipe.For example, the current invention can be used for producing any of following heat exchangers: a downsized heat exchanger where the gap (pitch) between each of the tube-grasping bodies is minimized, still avoiding contact with neighboring guide-pipes by allocating a tube-grasping body which is connected at its exterior to the guide-pipe, to each of straight tubes or hairpin tubes; and a heat exchanger where the gap between various types of insert tubes with different diameters and/or the gap between insert tubes is significantly reduced, for any of the following example cases: the case where the gap between straight tubes or hairpin tubes inserted into a heat radiating fin is reduced, in a heat exchanger downsized for savings in energy or cost, and/or the case where said gap between tubes being inserted in a zigzag pattern into a heat radiating fin is reduced, and/or the case where said gap is reduced, due to insertion of tubes in multiple columns such as columns of 3, 4, or etc. This can be connected externally to the tube-enlarging mandrel 2 from one end of the tube-grasping body 3 having a total length of the predetermined order positioned at the other end of the opening 7b of the tube 7, and a tube-grasping body 3 at one end near the inner tube-grasping body 3, which is cut by cutting with the prescribed depth inside the said tube-grasping body 3 at one end, forming a swelling part 3z that bulges to the axial direction of the tube-grasping body 3 to form a smaller inner diameter. After the site swelling part 3z, in order to form a tube-contacting part 3f with a plurality of tube-contacting parts 3f having bumps 3e that can freely compress and expand radially in the longitudinal direction of the tube 7 tube-grasping body 3, multiple slits 3a of prescribed length and width 3u along the longitudinal direction of the tube-grasping body 3, and from one end to the other end of the tube-grasping body 3, are formed in the axial direction of the tube-grasping body 3 by dividing the number of slits 3a and swelling parts 3z by the multiple slits 3a of the formed tube-contacting part 3f. A characteristic of this method is that each of the slits 3a, at a prescribed point, in the direction of the opening 7b of the tube 7, spreads so as to have an expanded width 3x which is gradually curved larger the prescribed width 3u, thereby providing the tube-contacting part 3f on the exterior surface. Moreover, the degree of inclination of the slope 3b in a direction that extends toward the opening 7b of the tube 7, from the formation process of the predetermined position on the tube-contacting part 3f that is greater than the degree of inclination when the slits 3a are formed, the tube-grasping body 3 having a plurality of tube-contacting parts 3f with bumps 3e that protrude into the axial direction of the tube-grasping body 3 can be produced.
