Abstract
The invention provides systems and devices for producing two-phase coolants such as an ice slurry. Also provided are methods for producing two-phase coolants, and methods for using the two-phase coolants to lower the temperature or maintain a low temperature in any subject, system, object, device, or application where particular low temperatures are desired. Also provided are systems for determining the cooling capacity of two-phase coolants.
Claims13
A device for producing an ice slurry, comprising:
- a housing comprising a heat exchanger, wherein the heat exchanger comprises at least one coolant and is configured to control the freezing temperature of a fluid;
- a driveshaft;
- at least one scraper blade coupled to the driveshaft, wherein the blade is configured to scrape ice from the side walls of the heat exchanger;
- an internal disk coupled to the distal end of the heat exchanger, wherein the internal disk is configured to hold a bearing positioned at a distal end of the driveshaft;
- a mixing vessel housing coupled to the housing comprising the heat exchanger, wherein the mixing vessel housing comprises a mixing vessel configured to receive ice slurry from the heat exchanger and to receive a high concentration saline solution, wherein the mixing vessel comprises a mixing blade.
2 more elements
A method for producing an ice slurry, comprising the steps of:
- contacting a low concentration saline solution with a heat exchanger, wherein the heat exchanger comprises at least one coolant and is configured to control the freezing temperature of the saline solution, and wherein a portion of the saline solution freezes within the heat exchanger and the remainder of the saline solution remains in the liquid state to form the ice slurry;
- and
- admixing a high concentration saline solution with the ice slurry.
