  • Patent number: 11659693
    Abstract: As air inside a building (e.g., a data center or any building that generates heat) becomes heated, it rises and is received or captured by a heat containment and then expelled from the building. The hot air is not recycle, recirculated, or re-cooled. Hot air being expelled from the building creates a pressure differential in which the pressure at the hot side of the building (where the heat containment is located) is lower than the cool side of the building. To this end, a chilling unit is installed at an opening of a building to supply cooled air at a constant rate. The chilling unit does not have an internal controller. Rather, an air conditioning (AC) unit of the building acts as an external controller. The AC unit is be set to maintain a target temperature and only runs when the temperature inside the building is above the target temperature.

  • Patent number: 11596084
    Abstract: A thermal module with a heat pipe configured with a first portion configured for contact with an edge of a plurality of fins in a fin stack, a second portion configured for contact with a side of one fin in the fin stack and a sharp angled bend is formed between the first portion and the second portion to fluidly isolate the first portion from the second portion. The first portion comprises a usable length of the heat pipe that efficiently transfers heat based on phase transitioning by the fluid. The second portion is formed from at least some of the unusable length of the heat pipe. By configuring the heat pipe such that more fins contact the usable length of the heat pipe, heat transfer from the heat pipe to the fin stack is increased.

    Abstract: Systems, apparatuses, and methods for efficiently performing active thermal control during device testing are disclosed. A device testing system includes a device under test, a thermal structure on top of the device under test, and a controller configured to determine when to apply and remove thermal energy to the device under test through the thermal structure. The thermal structure includes a thermal transfer block that transfers thermal energy to and from the device under test below the thermal transfer block. The thermal structure also includes a coolant block above the thermal transfer block that removes thermal energy from the thermal transfer block. There is no heating element between the coolant block and the thermal transfer block. Rather, the thermal structure includes a heating element in a wall of the thermal transfer block. Therefore, an unobstructed thermal path exists from the device under test to the coolant block.
