A heat exchanger may include a first container having a gas inlet, a liquid inlet, a gas outlet, and a liquid outlet. The gas inlet may flow a gas at a first temperature into the container while the liquid inlet introduces droplets of a liquid into the container at a second temperature. In the container, the liquid droplets may fall under the force of gravity while the gas flows through the container in a direction that is different from a direction of the spray of the liquid through the container. Accordingly, the liquid and the gas may come into direct contact within the first container and exchange heat. After the liquid and gas exchange heat, the liquid may leave the container through the liquid outlet and the gas may leave the container through the gas outlet.

A system and method for installing a water diversion system to a cooling tower flume and distribution basin to dam a section of the basin includes installing first and second basin dams extending radially from respective first and second parapets of the flume wall to the basin wall in sealing contact with a basin floor, blocking water from flowing from the undammed section of the basin into the dammed section using the basin dams, and installing a flume dam to each notch of one or more notches distributed peripherally along the flume wall between the first and second parapets, blocking water from flowing from the flume into the distribution basin through the one or more notches using the flume dam, and such that the flume dams installed to the one or more notches in combination with the first and second basin dams define a dammed section of the basin.

A cooling apparatus for cooling a waterflow is provided. Cooling apparatus includes a first evaporative cooler adapted to cool the waterflow therethrough, a second evaporative cooler adapted to receive and cool the waterflow from the first evaporative cooler therethrough, wherein the second evaporative cooler is adapted to receive an airflow therethrough to cool the waterflow therethrough and the first evaporative cooler is adapted to receive the airflow therethrough from the second evaporative cooler to cool the waterflow therethrough, and a deflector adapted to deflect the waterflow from the first evaporative cooler to the second evaporative cooler and allow the airflow from the second evaporative cooler to the first evaporative cooler therethrough. A cooling method for cooling a waterflow is also provided.

A heat exchange system for a surgical instrument includes a valve, a load, and a load conduit extending between the valve and the load. The load conduit delivers fluid from the valve to the load. The heat exchange system also includes an exhaust conduit that directs the fluid away from the valve. A portion of the load conduit is positioned so as to thermally transfer heat to a portion of the exhaust conduit.

A method for regulating climate, comprising: 1) allowing the formation of a relatively high temperature zone and a low temperature zone in the air above the ground; 2) allowing the formation of air convection between the high temperature zone and the low temperature zone as the cold air in the low temperature zone has a greater density than the hot air in the high temperature zone. A device for regulating climate is, i.e. an automatic air tower. The automatic air tower comprises a column (1) with an air inlet (12) at the bottom, wherein the column comprises a startup unit (13) and a shutdown unit (14) inside and has an air outlet (15) at the top. The aforesaid method and tower can prevent and eliminate the formation of haze and cool the earth's ground.
