  • Patent number: 11940227
    Abstract: A cooling system includes a heat exchanger having one or more rows of multiple flat tubes, louvered fins disposed between pairs of flat tubes, and special header tube connections to form a counter flow heat exchanger. Heat exchangers having multiple rows may be placed near or close to the server racks and may be in fluid communication with an outdoor heat exchanger having one or more rows. A single-phase fluid is pumped through a fluid circuit or loop, which includes the heat exchangers at the server racks and the outdoor heat exchanger. The single-phase fluid circuit including the heat exchangers at the IT racks may alternatively be in thermal communication with a water circuit that includes an outdoor fluid cooler. The flat tubes can be formed tubes with one or more channels, or extruded tubes with multiple channels. The heat exchangers include header tubes/connections, which facilitate easy fabrication and connection between rows and inlet/outlet, and lower the pressure drop.

  • Patent number: 11927363
    Abstract: An air curtain containment system and assembly for data centers forms an air curtain over the server cabinets thereby separating hot air in a hot aisle from cool ambient air. The air curtain containment system includes ducts which include a hot air intake section that receives hot air discharged from servers, which are disposed in server cabinets. The ducts include heat exchangers for cooling the hot air and at least one air curtain discharge section. A housing is coupled to a wall of the ducts, and includes a cooling edge device fan. The cooling edge device fan is disposed along the ducts, and is configured to draw the hot air for cooling through the heat exchangers. An air curtain fan assembly is disposed along the ducts. The air curtain fan assembly expels cold air through the air curtain discharge section, and thereby forms an air curtain over the server cabinets.

  • Patent number: 11867426
    Abstract: The cooling systems and methods of the present disclosure involve modular fluid coolers and chillers configured for optimal power and water use based on environmental conditions and client requirements. The fluid coolers include wet media, a first fluid circuit for distributing fluid across wet media, an air to fluid heat exchanger, and an air to refrigerant heat exchanger. The chillers, which are fluidly coupled to the fluid coolers via pipe cages, include a second fluid circuit in fluid communication with the air to fluid heat exchanger and a refrigerant circuit in thermal communication with the second fluid circuit and in fluid communication with the air to refrigerant heat exchanger. Pipe cages are coupled together to allow for expansion of the cooling system when additional cooling capacity is needed. The fluid coolers and chillers are configured to selectively operate in wet or dry free cooling mode, partial free cooling mode, or mechanical cooling mode.

  • Publication number: 20210315757
    Abstract: Protective shield unit provides a portable and reusable method for protecting medical staff during patient interaction. The protective shield unit is light weight, easily deployable, simple to use and reduces the amount of PPE that is needed by each medical staff. The protective shield unit includes an overhead frame that can be collapsible and a removably attachable flexible shield wall suspended from the frame for enclosing the patient. The shield wall is attachable to the frame from the outer surface of the shield wall such that the frame does not contact the inner surface of the shield wall, thereby blocking patient particulate exposure to the frame and preventing contamination during use.

  • Publication number: 20200229323
    Abstract: Modular air cooling and distribution systems include a fan and heat exchanger cooling assembly and a controller which controls the fan speed based on temperature and velocity measurements. The cooling assembly includes a fluid-to-air heat exchanger and a variable speed fan. The fluid in the fluid-to-air heat exchanger may be propylene glycol or water. The heat exchanger minimizes pressure drop and maximizes heat transfer. The quantity of cooling assemblies is selected to match the indoor cooling requirements. The cooling assemblies are easily assembled together, stacked vertically, and/or connected horizontally, to match the cooling load. If additional cooling capacity is needed in the future, more cooling assemblies can easily be added, and the cooling assemblies may be expanded vertically and/or horizontally. The speed of the fans of the fan and heat exchanger assemblies are controlled based on fluid temperature and fluid velocity measurements, which may be obtained by an anemometer.

    Abstract: A system and method for processing electronic devices to determine removal of customer personal information (CPI). An electronic device is connected to a test device. A number of electronic devices including the electronic device are received for determining that the CPI is removed from a number of sources. The number of electronic devices include a number of makes and models of electronic devices. A determination of whether CPI is included on the electronic device is made. An identification of the electronic device is recorded in response to determining that CPI is included on the electronic device. The CPI is cleared form the electronic device in response to determining that the CPI is included on the electronic device. The identification of the electronic devices and metadata is reported in response to determining the CPI was included on the electronic device.
