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： The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

摘要： A method for removing a surface foulant is disclosed. An operating heat exchanger is provided. A carrier liquid that contains potential fouling agents is provided to the heat exchanger. The potential fouling agents foul at least a portion of the heat exchanger. The exchanger is operated such that the carrier liquid is at a vapor pressure equal to the operating pressure. Cavitation inducing devices are provided to the exchanger. A condition indicating fouling is detected. The cavitation inducing devices are operated on a portion of the exchanger to cause a localized pressure change, vaporizing a portion of the carrier liquid and forming a transient bubble or bubbles which collapse by cavitation, producing a localized shockwave, a re-entrant microjet, and extreme transient pressures and temperatures. These steps are repeated as necessary to remove the surface foulant. In this manner, the surface foulant is removed from the operating heat exchanger.

摘要： A steam generator for generating steam by boiling water, or other hot water heating device, in either case such as for use in a steam cooker or warewasher, includes a tank structure providing a heating chamber for holding water and including a water inlet, a steam outlet and a water drain outlet. A heating element is located for heating water within the heating chamber so as to generate steam. At least one transducer is located on or within the tank structure to cause water within the heating chamber to vibrate so as to reduce scale build-up on one or more surfaces within the heating chamber.
