Abstract
A coolant distribution system uses two premixed streams of coolant at either extreme of a concentration range, and mixes these two streams in the correct percentage to obtain the desired concentration. Mixing the two streams follows a pulse width approach, and the system may use a manifold to deliver fluid to multiple machines.
Claims8
A coolant delivery system, comprising:
- a first mixing valve connected to a source of a first fluid and a source of a second fluid and having a first output of a first concentration of the first fluid and the second fluid;
- a second mixing valve connected to the source of the first fluid and the source of the second fluid and having a second output of a second concentration of the first fluid and the second fluid, the first concentration being different from the second concentration;
- and
- a valve arrangement connected to receive the first output and the second output and selectively deliver the first output or the second output to a manifold, the valve arrangement being operable under control of a controller to select one of the first output and the second output sequentially to produce a desired concentration of the first fluid and the second fluid in the manifold.
