摘要： An indirect heat exchanger has two airflow paths and an airflow generator to draw air through the airflow paths. A fluid conduit passes through the heat exchanger such that a cooling region is positioned within each of the flow paths. A dispenser is positioned to dispense evaporative liquid on one of the cooling regions. The dispenser operates in a wet mode and a dry mode. A controller regulates airflow through the first flow path and the second flow path, and also controls the operation of the dispenser. In this way, the controller may operate the airflow paths independently such that the airflow through a flow path operating in the dry mode is greater than that of the flow path operating in the wet mode.

摘要： A cooling tower is provided having a heat exchange section, and a fan for moving air through the heat exchange section. A water distribution assembly provides water onto and through the heat exchange section. An air inlet section is provided through which air is drawn into the cooling tower and the heat exchange section. The air inlet section has outside edges and corners. A wall assembly is provided in the air inlet section, with the wall assembly extending from the corners of the air inlet section inwardly. The water passing through the heat exchange section enters the air inlet section, and exits to a sump beneath the air inlet section. The air inlet section is comprised of a structure having outside edges and corners, and the wall assembly is comprised of a plurality of wall panel sections. Each wall panel section has an outer edge at a corner of the air inlet section, and each wall panel section extends inwardly from the corner of the air inlet section.

摘要： In one aspect of the present disclosure, an indirect heat exchanger pressure vessel is provided that includes an inlet header to receive a pressurized working fluid, such as water, glycol, ammonia, and/or CO2. The indirect heat exchanger pressure vessel includes an outlet header to collect the pressurized working fluid and a serpentine circuit tube connecting the inlet and outlet headers. The serpentine circuit tube permits the pressurized working fluid to flow from the inlet header to the outlet header. The serpentine circuit tube includes runs and a return bend connecting the runs. The return bend has a controlled wrinkled portion comprising alternating ridges and grooves. The alternating ridges and grooves strengthen the return bend and permit the indirect heat exchanger pressure vessel to facilitate working fluid heat transfer at a high internal operating pressure.

摘要： FIG. 1 is a front perspective view of a heat exchanger tube in accordance with our new design;
FIG. 2 is a right side view thereof, the left side view being a mirror image thereof;
FIG. 3 is a front view thereof;
FIG. 4 is a rear view thereof;
FIG. 5 is a top view thereof; and,
FIG. 6 is a bottom view thereof.
The broken lines in the drawings illustrate portions of the heat exchanger tube that form no part of the claimed design.
The heat exchanger tube is shown with a symbolic break in its length. The break lines and the appearance of any portion of the heat exchanger tube between the break lines form no part of the claimed design.-

摘要： In one aspect, a cooling tower system is provided that includes an evaporative heat exchanger, a sensor configured to detect a parameter of evaporative liquid distributed onto the evaporative heat exchanger, and an evaporative liquid treatment system. The cooling tower system further includes a controller having a normal operating mode wherein the controller operates the evaporative liquid treatment system to treat the evaporative liquid upon a determination of inadequate evaporative liquid quality based at least in part on the parameter of the evaporative liquid. The controller has a failsafe operating mode wherein the controller changes operation of the cooling tower upon a determination that the operation of the evaporative liquid treatment system is unable to remedy the inadequate evaporative liquid quality.
