Cooling control methods and systems include measuring a temperature of air provided to one or more nodes by an air-to-liquid heat exchanger; measuring a temperature of at least one component of the one or more nodes and finding a maximum component temperature across all such nodes; comparing the maximum component temperature to a first and second component threshold and comparing the air temperature to a first and second air threshold; and controlling a proportion of coolant flow and a coolant flow rate to the air-to-liquid heat exchanger and the one or more nodes based on the comparisons.

The present invention is a complete solution for mission critical facilities to create a safe environment and energy efficient CRAC system. The invented system collects mission critical facility volume environmental and energy data in real time, and uses big data analytics to provide adaptive group control to CRACs. The data is visualized in 2D and 3D graphs, dashboard, history curves and reports locally and through the cloud. The present invention also provides user management to allow authorized users to view and control the racks/servers owned or rented by these users. The present invention is comprised of four companion patents: 1) A Battery-powered Wireless Long Life Temperature and Humidity Sensor Module, 2) An Intelligent Multi-channel Wireless Data Acquisition Gateway, 3) Mission critical facility Three Dimension Temperature Contour Generator, and 4) An Adaptive Automatic CRAC Master Control Method.

Intelligent mission critical environmental monitoring and energy management system

A monitoring system can receive sensor measurements from a select sensor of a group of sensors. The sensor measurements are compared to group alert condition or an individual alert condition. Based on the comparison, an alert state can be identified and a user notified of the alert state. The system can automatically determine the individual alert condition, which can be uniquely associated with the select sensor and can be associated with a domain of time.

Climate regulation within an enclosure (e.g., a case of a workstation or a rack or cabinet of servers) may be achieved through a climate regulator featuring several selectable climate regulator settings (e.g., a variable-speed fan array). Controllers of such climate regulators often select climate regulator settings based on current conditions inside the enclosure, such as the temperature of one or more processors operating within the enclosure. However, such control fails to account for the climate of air outside the enclosure that is drawn in to provide climate regulation, even though the climate properties of inlet air may significantly affect the effectiveness of climate regulation. Accordingly, a controller of a climate regulator may be configured to detect inlet climate properties of air directed into the enclosure, and to map the inlet climate properties (alone or in combination with other factors) to a selected climate regulator setting for the climate regulator.

A method and/or computer program product automatically adjusts room temperature in a data center room A processor in a heating, ventilation and air conditioning (HVAC) system receives a throttle threshold temperature for each of multiple computing devices that are within a data center room, which is climate-controlled by the HVAC system The processor in the HVAC system monitors a real-time temperature of at least one of the multiple computing devices In response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature, an ambient air temperature in the data center room is decreased by adjusting a hardware thermostat in the HVAC system

A computer program product including computer usable program code embodied on a computer usable medium for controlling a temperature within a computer system using a fan. The computer program product includes computer usable program code for monitoring the temperature within the computer system; dynamically selecting a fan speed step in response to the temperature, wherein the fan speed step is selected from a fan speed table defining a finite number of fan speed steps each having an associated fan speed; operating a fan at the dynamically selected fan speed step; measuring a fan output variation is measured over a prescribed time interval; and automatically modifying the fan speed table to change the fan speeds associated with each fan speed step, wherein the fan speeds are changed as a function of the measured fan output variation while continuing to drive the fan.

A heat sink comprises a plurality of fins that may be positioned in a plurality of orientations relative to a heat-generating electronic component to which the heat sink is thermally coupled. A controller may be used to detect an elevated processor temperature and to activate a drive member to automatically adjust the orientation of fins on the heat sink. The fins may be moved and aligned with an air flow made over the heat sink. The adjustable-fin heat sink affords added flexibility in arranging a processor or other heat-generating electronic component on a circuit board. The orientation or position of the heat sink fins may also be automatically changed in response to a change in the air flow direction as manifested by a rise in the temperature of the heat sink or the heat-generating member.

A computer system has a plurality of heat-generating computer devices arranged in a data center, a cooling system in the data center, and a real-time cooling controller. The cooling system is configured for directing a cooling fluid to a plurality of different zones of the computer system, where each zone is occupied by a different subset of the heat-generating devices. The real-time cooling controller is configured for monitoring a power consumption of the heat-generating devices at each zone, independently controlling a cooling fluid flow rate to each zone, targeting one of the zones for increased cooling in response to a detected increase in the power consumption at the targeted zone, and increasing the cooling fluid flow rate to the targeted zone in immediate response to the power consumption increase.

One embodiment provides a vapor chamber having an outwardly protruding boss. A frame surrounds a perimeter of the vapor chamber. A plurality of heat sink fins extend from the frame. A cross-member spans the frame across the vapor chamber wall and defines an opening through which the boss protrudes at least slightly beyond the cross-member. The heat sink may be secured to a socket on a circuit board, with the boss engaging a processor positioned in the socket. In response to securing the heat sink, the boss compresses flush with the cross-member and the cross-member engages the processor to seat the processor in the socket. The opening in the cross-member reinforces the boss against outward deformation.

An electronic system comprises: at least one electronic component; a cooling system condition receiver, wherein the cooling system condition receiver is capable of receiving a condition signal, and wherein the condition signal describes a current condition of a cooling system that provides conditioned air to an ambient environment of the electronic system; and a throttle, wherein the throttle, in response to the cooling system condition receiver receiving the condition signal that describes the current condition of the cooling system, adjusts an amount of heat generated by said at least one electronic component by throttling back operations of said at least one electronic component.
