Abstract: Hindered cyclic polyamines and their salts are absorbents useful in acid gas treatment processes.

Abstract: A heatsink module for electronic device includes a heatpipe, a board, a heatsink and at least a resilient plate. The board is mounted on one end of the heatpipe, and formed with at least a fixing hole. The heatsink is mounted on the other end of the heatpipe. The resilient plate fastens the board onto the electronic component of the electronic device. The resilient force of the resilient plate helps the board accommodated to the height of the electronic component and well contact with the electronic component. The board is made by stamping; therefore, the manufacture cost is lower. Also, the board and the resilient plate are thinner so as to reduce the height of the installation and help the thinness of electronic device.

Abstract: Disclosed is a heat sink module for an electronic device, comprising a substrate having at least a fixed hole, at least a heat sink fin set disposed on the substrate and having a plurality of heat sink fins and at least a resilient plate disposed on the substrate and having at least a mount hole mounting the substrate on an electronic device component in the electronic device in coordination with the fixed hole so that the substrate can be closely bonded to a surface of the electronic component. Further, since the heat sink fin set is formed on the substrate by punching method, an advantage of low cost of the heat sink module is provided.

Abstract: The present invention provides a heatsink structure with an air duct, which is utilized to dissipate heat from heat-generating elements. The heatsink structure comprises a heatsink module, an air duct, and a fan module, wherein the cooling wind generated by the fan module is guided through the air duct toward the heatsink module to dissipate the heat therefrom. Via the design of the air duct of the present invention, not only the fast assembling and disassembling of the heatsink module can be achieved, but the efficiency or the cost of the installing, maintaining and changing for upgrade of the CPU and the video chipset can also be promoted or reduced.
