US Patent 11252849 Cooling of electronic displays

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.
