Abstract
A two-phase immersion cooling apparatus may include an immersion tank with a primary condenser in thermal communication with an interior volume of the immersion tank and a vapor management system fluidically connected to the immersion tank. The vapor management system may enable the apparatus to effectively manage periods of high vapor production by removing vapor and other gases from a headspace of the immersion tank, condensing the vapor to liquid, and returning the liquid to the immersion tank.
Claims20
A two-phase immersion cooling apparatus comprising:
- an immersion tank comprising an upper portion, a lower portion, and a primary condenser in thermal communication with an interior volume of the immersion tank;
- and
- a vapor management system fluidly connected to the immersion tank, the vapor management system comprising:
- a condensing chamber having an inlet, an outlet, and an auxiliary condenser in thermal communication with an interior volume of the condensing chamber;
- a vapor supply passage fluidly connecting the upper portion of the immersion tank to the inlet of the condensing chamber;
- a valve in the vapor supply passage between the upper portion of the immersion tank and the inlet of the condensing chamber;
- and
- a liquid return passage fluidly connecting the outlet of the condensing chamber to the immersion tank.
A two-phase immersion cooling apparatus comprising:
- an immersion tank comprising an upper portion, a lower portion, and a primary condenser in thermal communication with an interior volume of the immersion tank;
- and
- a vapor management system fluidly connected to the immersion tank, the vapor management system comprising:
- a condensing chamber having an inlet, an outlet, and an auxiliary condenser in thermal communication with an interior volume of the condensing chamber;
- a vapor supply passage fluidly connecting the upper portion of the immersion tank to the inlet of the condensing chamber;
- a solenoid valve in the vapor supply passage between the upper portion of the immersion tank and the inlet of the condensing chamber;
- a liquid return passage fluidly connecting the outlet of the condensing chamber to the immersion tank;
- a pressure sensor configured to detect pressure in the immersion tank;
- and
- an electronic control unit configured to receive a pressure signal from the pressure sensor and send a command signal to the solenoid valve.
A method comprising:
- providing a two-phase immersion cooling apparatus comprising:
- an immersion tank comprising an upper portion, a lower portion, and a primary condenser in thermal communication with an interior volume of the immersion tank;
- and
- a vapor management system comprising:
- a condensing chamber having an inlet, an outlet, and an auxiliary condenser in thermal communication with an interior volume of the condensing chamber;
- a vapor supply passage fluidly connecting the upper portion of the immersion tank to the inlet of the condensing chamber;
- a valve in the vapor supply passage between the upper portion of the immersion tank and the inlet of the condensing chamber;
- and
- a liquid return passage fluidly connecting the outlet of the condensing chamber to the immersion tank;
- detecting a pressure within the immersion tank;
- opening the valve when the pressure is greater than a predetermined threshold setting and admitting dielectric vapor from the immersion tank into the condensing chamber;
- closing the valve when the pressure in the immersion tank is less than the predetermined threshold setting;
- condensing the dielectric vapor to a liquid in the condensing chamber;
- and
- returning the liquid to the immersion tank through the liquid return passage.
