摘要:
An immersion cooled electronic arrangement (100; 200; 300) includes a sealed housing (102; 202), a coolant (C) contained within the housing (102; 202), and an electronic device (104; 204; 304) submerged within the coolant (C). An agitator (106; 206) is disposed within the housing (102; 202) to control passive heat transfer between the electronic device (104; 204; 304) and the coolant (C). An immersion cooling system and related method are also described.
摘要:
Computer thermal regulation (CTR) systems and methods for thermal energy (TE) regulation of vehicle computers designed to operate within a target temperature range (TTR). A vehicle HVAC system includes a computer heat exchanger in the computer including a phase change material (PCM) with a phase change temperature (PCT). When the computer is below a TTR lower limit, the CTR system causes the HVAC system to run a heating cycle, heating the PCM to and above the PCT. The PCM releases stored TE to the computer. When the CTR system is above a TTR upper limit, the CTR system causes the HVAC system to run a cooling cycle, cooling the PCM to and below the TTR. The PCM then absorbs heat from the computer. TE storage and release processes during phase changes enable the PCM to operate as a buffer between the HVAC system and the computer to allow finer control over the computer temperature with an otherwise overpowered HVAC system for the vehicle.

The invention relates to a device comprising an electronic housing (10) and a tubular cooler (65) with a tube (70) made as a single piece and of a single material. The tube (70) comprises a tube coil (85) and a first tube section (90, 95), between which the electronic housing (10) is arranged, and a first connection section (100, 105). The first connection section (100, 105) fluidically connects the first tube section (90, 95) to a first side (155) of the tube coil (85). The first tube section (90, 95) can be connected to a coolant supply and is arranged such that it is laterally offset in relation to the tube coil (85). The tube coil (85) and the first tube section (90, 95) extend on the same side of the first connection section (100). The first connection section (100) runs in an inclined manner in relation to the tube coil (85) and the first tube section (90, 95) and/or in a curved manner from the tube coil (85) to the first tube section (90, 95).

An automated vehicle (AV) can include a data processing system housed in a cooling rack, and a thermal reduction system to provide cooling for the data processing system. The thermal reduction system can include a fluid pump to pump cooling fluid through the cooling rack, a cabin radiator to receive the cooling fluid and pump cabin air from the interior cabin of the AV to cool the cooling fluid, and a main radiator to receive the cooling fluid and pump outside air to further cool the cooling fluid. Additionally, the thermal reduction system can include a secondary cooling unit that includes a condenser, evaporator, and compressor pump to further cool the cooling fluid.

摘要:
The invention relates to a cooling system for a power electronic unit for operating at least one electrical group of a motor vehicle, especially of a starter/generator comprising a pressure-sealed receptacle (2) for accommodating an electronic arrangement (1) and a bath (3) which covers the same and which is comprised of an electrically insulating first cooling fluid. At an operating pressure, the boiling temperature of said cooling fluid does not exceed the still permissible operating temperature of the electronic arrangement (1). The inventive cooling system also comprises a heat exchanger (5) which is arranged above the level of the first cooling fluid or which is connected to the same via a line configuration (9). In the electronic arrangement (1), vaporized first cooling fluid arrives in the heat exchanger (5) as vapor, is condensed there and returns to the bath again (3), whereby a first cooling fluid circuit is produced. The invention is characterized in that a second cooling fluid circuit having a second cooling fluid is provided which comprises a cooler (8) and which cools the heat exchanger (5). Said second cooling fluid circuit (6) comprises at least one cooling fluid low point which is located under the heat exchanger (5). In addition, the second cooling fluid circuit (6) comprises a pump (7) for forcing a circulating flow of the second cooling fluid.
