Cleaning the inside surfaces of tubes in a cracking furnace, or other type of structure with tubes, is very difficult and time consuming. An acoustic energy cleaning apparatus is provided that is clamped onto a tube, and a liquid solvent is filled within the tube. The cleaning apparatus includes an ultrasonic transducer that causes cavitation of the liquid inside the tube, which dislodges material build-up. The apparatus also includes a rigid seal cover that encompasses a lower portion of a transducer housing, and an annular resilient seal positioned within and below the seal cover. The apparatus also includes an injection hole that fluidly connects a space, defined at least by the annular resilient seal and a bottom surface of the acoustic transducer, to an external environment. A user injects gel into the injection hole.

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.

An adiabatic cooling system includes a condenser coil and one or more adiabatic pads positioned such that intake air for the adiabatic cooling system passes through the pads prior to contacting the condenser coil. The adiabatic cooling system includes a vibration device attached to each adiabatic pad. A controller is communicatively coupled to the vibration device for each of the adiabatic pads. The controller determines that cleaning of the adiabatic pads is needed. In response to detecting cleaning is needed, the controller causes the vibration device attached to each adiabatic pad to vibrate.
