Publication number: 20250113467Abstract: An electronic display includes a housing, display panels within the housing, and a heat exchange unit within the housing adjacent to the display panels. The display panels have a display surface visible through the housing. Each display panel is in a first substantially sealed enclosure through which internal air is circulated to cool the display panel. The heat exchange unit includes a plurality of tubes in a second substantially sealed enclosure. First fans are arranged to circulate the internal air through or around the plurality of tubes to cool the internal air, the air flowing in a first direction. Second fans are arranged to pass external air around or through the plurality of tubes to cool them, the air flowing in a second direction that is substantially opposite to or the same as the first direction.Type: ApplicationFiled: January 17, 2023Publication date: April 3, 2025Inventors: Stephen Whitehead, Jonathan Shires, Gary Greenwood

Patent number: 11624520Abstract: An electronic apparatus includes a housing with a power supply unit that receives external electrical power and supplies it to the apparatus using a power controller. The housing includes a heater; temperature and humidity sensors; and an electronic processor that receives power from the power supply unit and controls functions of the electronic apparatus. Upon startup, the power controller receives data from the temperature and humidity sensors; processes the received temperature and humidity data to indicate a current dew point within the housing; and compares the current dew point with a current location temperature at a location within the housing. If the current location temperature is at or below the current dew point, the heater is activated to raise the temperature within the housing. If the current location temperature is above the current dew point, electrical power supplied from the power supply unit to the electronic processor.Type: GrantFiled: April 30, 2018Date of Patent: April 11, 2023Assignee: AMSCREEN GROUP LIMITEDInventors: Stephen Whitehead, Jonathan Shires, Gary Greenwood, Peter Francis

Patent number: 11252849Abstract: An electronic display has a housing with different regions and a display panel with a display surface. A cooling module flows internal coolant through the cooling module and the regions. The cooling module has a crossflow heat-exchanger and side walls. The regions and cooling module have an coolant inlet and outlet. The coolant inlets of the regions communicate with the coolant outlet of the cooling module. The coolant outlets of the regions communicate with the coolant inlet of the cooling module. The regions have their own circulating loop of coolant, with flow of coolant being deflected from the outlet of the cooling module towards the coolant inlets of the regions, and flow of coolant from the coolant outlets of the regions being deflected towards the coolant inlet of the cooling module. The coolant flows in parallel over both front and back of the display panel.Type: GrantFiled: April 30, 2018Date of Patent: February 15, 2022Assignee: Amscreen Group LimitedInventors: Stephen Whitehead, Jonathan Shires, Gary Greenwood, Peter Francis

Patent number: 11071231Abstract: An electronic apparatus has a heat-exchanger within a housing exchanges heat between internal and external fluids without direct contact between the fluids. The internal fluid circulates within the housing and the external fluid is received external from the housing and output external from the housing 120. The housing includes is a heater; impellers; a controller for controlling the heater and the flow of fluids through the heat-exchanger; and temperature and humidity sensors. The controller receives temperature and humidity data from the sensors; processes the data to indicate a current dew point within the housing; and compares the current dew point with a current location temperature at or adjacent the heat-exchanger. If the current location temperature is at or below the current dew point, the controller raises the temperature at at least one location on the heat-exchanger and/or activates the heat source to raise the temperature.Type: GrantFiled: April 30, 2018Date of Patent: July 20, 2021Assignee: AMSCREEN GROUP LIMITEDInventors: Stephen Whitehead, Jonathan Shires, Gary Greenwood, Peter Francis

Patent number: 11016547Abstract: An electronic display has a display panel with a display surface visible through a housing. A processor controls functions of the display and operating conditions within the housing. Input sensors are disposed within the housing and sense operating conditions within the housing. Output components respond to control signals. Modules have a unique address identifier and a connection to one of the input sensors and output components. A CAN bus communicates between the modules and electronic processor. Processing of signals received from the input sensors and control signals is distributed amongst microcontrollers on the modules. The processor uses a unique address identifier to receive a temperature reading from a module connected to a temperature sensor; process the temperature reading to determine one or more new fan speed setting; and send data via the bus to a module to a fan speed to the new setting.Type: GrantFiled: April 30, 2018Date of Patent: May 25, 2021Assignee: AMSCREEN GROUP LIMITEDInventors: Stephen Whitehead, Jonathan Shires, Gary Greenwood, Peter Francis

Patent number: 10905035Abstract: A crossflow heat-exchanger has first and second sets of fluid-flow channels arranged such that each set crosses the other to afford heat-exchange between cooling air in the first set and hot air in the second set, without the cooling air and the hot air contacting one another. A first series of fans causes flow of the external cooling air through the rows. A second series of fans causes flow of the internal hot air through the columns. External and internal fan controllers control the speed of each fan independently such that external cooling air flows through different rows at different rates and internal hot air flows through different columns at different rates.Type: GrantFiled: April 30, 2018Date of Patent: January 26, 2021Assignee: AMSCREEN GROUP LIMITEDInventors: Stephen Whitehead, Jonathan Shires, Gary Greenwood, Peter Francis
