Horizontal Extraction and Return Extensions in liquid storage tanks

a liquid storage tank and horizontal extraction technology, applied in the direction of fluid heaters, lighting and heating apparatus, transportation and packaging, etc., can solve the problems of no practical limitation preventing incorporation, large liquid storage tanks are usually unpressurized, and high storage volume, so as to enhance thermal stratification within the tank, reduce or eliminate flow velocity, and facilitate connection

Abstract

This invention is an improvement to the shape of liquid storage tanks, in particular to unpressurized molded polymer tanks used for thermal storage in solar systems. All aspects of this invention are well suited to solar storage tanks, and individual aspects are suited to other liquid tank applications.This invention provides a formed horizontal extension at the bottom of the tank. From the top of this lower extension, a hollow vertical stub provides a reliable connection to a circulator pump. Thermal performance is enhanced by ensuring the lowest and coolest water is delivered to the array of rooftop solar collectors without entraining debris from the bottom of the tank.At the top of the tank, a similar horizontal extension is used to distribute hot water returning from the solar collectors. Flow velocity is eliminated and a curving lower edge allows return water to find the matching thermocline to avoid de-stratifying.

[0004] Not applicable.BACKGROUND OF THE INVENTION

[0005] There are three methods commonly used in the production of liquid storage tanks. Steel and stainless steel tanks are fabricated from sheet material that is cut and welded, either automated or by hand. Their resistance to elevated pressures and temperatures makes them popular for domestic water heaters an...
