The tube cleaning device has a frame having a plurality of top and bottom vertical slots and a first and second upper slotted bracket, each bracket being located above an upper and lower window. First and second lower brackets are located below the windows forming a ledge. First and second riggings engage the slots and releasably connect the frame to a tube bank. A spreader bar is inserted through a window. A releasable connector secures the spreader bar to the frame. A vibrating motor is releasably secured to the frame. Vibration of the motor is passed through the frame to the spreader bar, which vibrates the tubes to effectuate cleaning.

A heatsink comprising a heat exchange device having a plurality of heat exchange elements each having a surface boundary with respect to a heat transfer fluid, having successive elements or regions having varying size scales. According to one embodiment, an accumulation of dust or particles on a surface of the heatsink is reduced by a removal mechanism. The mechanism can be thermal pyrolysis, vibration, blowing, etc. In the case of vibration, adverse effects on the system to be cooled may be minimized by an active or passive vibration suppression system.
