Problems solved by technology

Operating the transformer at saturation results in increased eddy current and hysteresis losses
The combination of excessive heat generation and operation at magnetic saturation significantly reduces efficiency and negatively affects transformer life
[0006] Although the '600 and '267 patents also describe the use of full wave rectifiers to power the coils, this setup is also problematic
With full wave rectification, the coil loop is limited by the other half of the AC cycle

Embodiment Construction

[0018] The present invention relates to fluid handling devices that can be used in a wide variety of applications. In an embodiment, the fluid handling device can be used in an environment such as a vapor cooler where water is repeatedly circulated through the cooler and scale and microbes can be generated. It is also contemplated to use this device in other types of environments, such as heating systems. In order to provide a description of embodiments of the present invention, fluid handling devices are discussed in terms of use with one or more fluid conduits, it being understood that the conduits can be used to carry heated or cooled water, or other fluids, as desired.

[0019] like figure 1 As schematically illustrated in , a fluid treatment device 20 is provided for connection to an AC power source 24 having a maximum voltage via a plug 22 or other electrical connection such as a direct hardwired connection. The AC power source may typically be a power line supplied by...

Abstract

A fluid treatment device includes an AC power source connected to first, second and third conductors. A electromagnetic field generating device is positioned adjacent to a fluid conduit, electrically connected to the first and third conductors to form a first circuit. A second electromagnetic field generating device is positioned adjacent to a second fluid conduit, electrically connected to the second and third electrical conductors to form a second circuit. A circuit element in the first circuit initiates a high frequency electromagnetic field at said first electromagnetic field generating device during a first half of the AC wave form in the first circuit, and a circuit element in the second circuit initiates a high frequency electromagnetic field at said first electromagnetic field generating device during a second half of the AC wave form in the second circuit.

Description

technical field [0001] The present invention relates to devices for treating fluids, such as water, and in particular to fluid treatment devices powered to provide electric and magnetic fields in the fluid. Background technique [0002] Fluid handling utilizing DC powered solenoid coils has been used for many years. This arrangement is shown in US Patent No. 4,938,875. DC power can be provided by a DC source (battery) or a rectified AC source. For example, US Patent Nos. 5,702,600, 6,063,267, and 6,146,526 have modified the AC method by using only the rectified half-wave to generate DC power (no smoothing power capacitors) and turning off the coil loop with current for the second half-wave. During periods of no current, the coils will ring at their resonant frequency (which can be modified by adding a small capacitance) and emit a high frequency field into the fluid to be treated. In the '600 patent, diodes are used to rectify the wave, while in the '267 patent, triodes a...
