Abstract
In an apparatus for enhancing convection of air at a working element of a heat exchanger, a main flow of air is directed toward the working element. A priming flow of pressurized air is provided to impinge upon the working element, to disrupt a stagnant boundary layer adjacent the working element, and to thereby enhance the main flow of air.
Claims16
An apparatus for enhancing convection of air at a working element of a heat exchanger, comprising:
- means for providing a main flow of air directed toward the working element;
- and
- means for producing a priming flow of pressurized air that impinges upon the working element to disrupt a stagnant boundary layer adjacent the working element.
An apparatus for enhancing natural convection of ambient air at a working element of a heat exchanger, comprising:
- a substantially closed and elongated plenum extending generally parallel to and proximate the working element, the plenum being filled with pressurized air and having at least one opening disposed such that a first quantity of the pressurized air exits the opening as a priming air flow and induces a second quantity of ambient air to flow as a main air flow onto and across a surface of the working element.
A method for enhancing convection at working element of a heat exchanger, comprising:
- supplying at least one pressurized priming air flow onto the working element, substantially without obstructing access of a main air flow to the working element, whereby the priming air flow induces an increase of the main air flow adjacent to the working element.
