摘要： 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.

摘要： A method of cleaning an HVAC coil unit located above a drain basin. One step of the method involves providing a supply and collection assembly having a reservoir containing liquid cleaning solution, a pump operative to output the liquid cleaning solution through a supply outlet, and a vacuum source operative to draw in used liquid cleaning solution through a collection inlet. According to another step, a nozzle device in fluid communication with the supply outlet is also provided, the nozzle device having a delivery face. A further step involves providing a fluid return tool in fluid communication with the collection inlet, and positioning the fluid return tool in the drain basin. According to a further step, the delivery face of the nozzle device is moved across a surface of the HVAC coil unit to deliver the cleaning solution into areas between fins thereof.

摘要： The present disclosure relates generally to water jet equipment. Specifically, water jet equipment that includes a support frame comprised of a plurality of stackable trollies that support a plurality of lances as those lances are inserted into and withdrawn from heat exchanger tubes during a cleaning operation of the same. A method of cleaning elongated tubes by positioning and rotating the lances while moving in a first direction is further provided.

摘要： A process for removing or reducing the accumulation of foulant within furnaces and heat exchangers in industrial systems such as an oil refinery by introducing a periodic steam blast. The steam blast is directed into the fluid stream from which the foulants form on to the heat exchanger surfaces. The steam blast increases the flow rates, creates turbulence and increases the temperature within the heat exchanger to dislodge foulant in both a soft and hardened states from internal surfaces upon which foulants have adhered and accumulated.

摘要： Systems and methods for cleaning a heat recovery steam generator system including tubes and fins associated therewith using deep cleaning alignment equipment are described. The deep cleaning alignment equipment primarily includes at least one wedge and at least one wand. The wedge may be an elongate wedge configured to maximize the surface area that contacts the tubes and fins, which in turn minimizes the amount of stress about any specific point of the tubes or the fins. Additionally, the wedge may be made of a soft, composite material, such as a high strength carbon fiber nylon. The composite material is softer than the material that makes the tubes and fins. As a result, when the wedge contacts the tubes and fins, the tubes and fins will not sustain damage. Instead, any damage that may occur would be to the wedge.
