摘要： Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes through which refrigerant flows, a fin disposed between adjacent refrigerant tubes to conduct heat, and a sacrificial sheet configured such that a first surface thereof contacts the refrigerant tube and a second surface thereof contacts the fin. A corrosion potential of the sacrificial sheet is lower than a corrosion potential of the refrigerant tube.

摘要： A reinforcing insert (100) for a heat exchanger tube (102) is disclosed. The reinforcing insert (100) includes at least two spaced legs (104) adapted to be received in the heat exchanger tube (102) through an open end (106a, 106b) of said tube (102), each of the at least two legs (104) being configured such that at least two side surfaces (108a, 108b) of each of the legs (104) are abutted with at least two inner side surfaces of the heat exchanger tube (102), and an outer connector (112) adapted for connecting outer ends of the at least two legs (104) and positioned outside of said tube (102). In addition, at least a portion (114a, 114b) of the outer connector (112) is bent at a predefined angle with respect to adjacent connecting portions (116) coupled to the at least two legs (104).

摘要： The present invention relates to a heat exchange fin, with a tube hole formed thereon for a heat exchange tube to be inserted into, and with a corrugated structure arranged near the tube hole, wherein the corrugated structure comprises a wave section arranged along a flow direction of fluid medium, where a distance between two adjacent wave crests or wave troughs of the wave section is one wavelength, and the total length of the wave section is 1-1.5 times the wavelength, wherein, a bridge plate is further arranged at the wave crests and wave troughs of the wave section, respectively, where the bridge plate deflects relative to the wave crests and wave troughs by a preset distance. The present invention also proposes a heat exchanger configured with the heat exchange fins, and a heat pump system configured with the heat exchanger. The heat exchange fins according to the present invention can significantly improve the heat transfer efficiency of the heat exchange fins, thereby greatly enhancing the heat exchange effect.

摘要： A cooling system includes a heat exchanger having one or more rows of multiple flat tubes, louvered fins disposed between pairs of flat tubes, and special header tube connections to form a counter flow heat exchanger. Heat exchangers having multiple rows may be placed near or close to the server racks and may be in fluid communication with an outdoor heat exchanger having one or more rows. A single-phase fluid is pumped through the fluid circuit or loop, which includes the heat exchangers at the server racks and the outdoor heat exchanger. The single-phase fluid circuit including the heat exchangers at the IT racks may alternatively be in thermal communication with a water circuit that includes an outdoor fluid cooler. The flat tubes can be formed tubes with one or more channels, or extruded tubes with multiple channels. The heat exchangers include header tubes/connections, which facilitate easy fabrication and connection between rows and inlet/outlet, and lower the pressure drop.
