A reliable, leak-tolerant liquid cooling system with a backup air-cooling system for computers is provided. The system may use a vacuum pump and a liquid pump and/or an air compressor in combination to provide negative fluid pressure so that liquid does not leak out of the system near electrical components. Alternatively, the system can use a single vacuum pump and a valve assembly to circulate coolant. The system distributes flow and pressure with a series of pressure regulating valves so that an array of computers can be serviced by a single cooling system. A connector system is provided to automatically evacuate the liquid from the heat exchangers before they are disconnected. Leah detection and mitigation structures are also disclosed. Various turbulators are also provided, as well as a system and method for optimizing the heat transfer characteristics of a heat exchanger to minimize total energy requirements.

Cooling towers and cooling tower fill configured for the cooling of process water with air by indirect heat exchange, in which the fill is configured with a first set of channels and a second set of channels, said first and second set of channels interleaved with one-another so that heat exchange occurs across material separating said channels from one-another.

A cooling recover system and method are disclosed. A fluid, such as water, is chilled and provided to a cooling coil to cool and dehumidify air passing over the cooling coil. The fluid is output from the cooling coil through an outlet, and at least a portion of the fluid from the outlet of the cooling coil is provided to an inlet of a heat transfer coil to reheat air passing over the heat transfer coil. The fluid is warmed as it passes through the cooling coil, which warmer temperature serves to reheat the air passing over the heat transfer coil.

A heat transfer process focused for heating or cooling an aggressive liquid employing direct contact through an immiscible fluid film of differing density. The fluid film adheres to a solid wall heat transfer surface purveying both transference of heat therein as well as isolation protection of the heat transfer surface from damage, coating or scaling from the adjacent aggressive liquid.

The portable evaporative cooler for vehicles includes a housing with a hanging hook and suction cups for selective mounting to a side window of a vehicle. The housing is divided into various interior compartments for an airflow manifold, a misting assembly, and a heat exchange system. The airflow manifold includes a fan that positively feeds ambient air through a first heat exchanger to pre-cool the air prior to subjecting the same to a moisture mist from the misting assembly for further cooling. The cooled air flows through a second heat exchanger for final cooling prior to exiting the housing and into the interior of the vehicle. The fan forces airflow in one direction to recycle the ambient air through the housing. A controller is coupled to a temperature sensor and a humidity sensor to monitor the air and control the components to cool the air to desired or predetermined levels.

The system comprises a plurality of first fluidic flow channels and a distribution device fed by a flow of a first fluid, notably a liquid, and injecting the flow of first fluid into the plurality of first channels at an output of the distribution device. The output of the distribution device consists of an distribution element for the first fluid, notably formed in a porous material, configured in such a way as to be passed through by the first fluid with a pressure drop such that the first fluid leaves from the distribution element with a uniform surface distribution at an output surface of the distribution element, in a way that ensures a uniform feed of first fluid for the first channels.
