Compact Cooling System and Method for Accurate Temperature Control

摘要

In an integrated two-phase accumulator controlled loop cooling system, the pumped refrigerant is employed to cool the supply of refrigerant in the accumulator vessel. No external cooling of the accumulator vessel is required, and a standard heater in the accumulator is sufficient to regulate the boiling pressure. This allows to provide a cooling system in which sub-cooling in the pump is guaranteed by the laws of nature, and which is hence more reliable, structurally simpler, better to control and cheaper.

1. A cooling system comprising:
a liquid pump having an inlet and an outlet, said liquid pump adapted for pumping a liquid refrigerant; an inlet fluid path for said refrigerant, said inlet fluid path connected to said inlet of said liquid pump; an accumulator adapted for storing a supply of said refrigerant, said accumulator being in fluid communication with said inlet fluid path; a condenser adapted for cooling said refrigerant, said condenser arranged in said inlet fluid path between said accumulator and said inlet of said liquid pump; and an outlet fluid path for said refrigerant, said outlet fluid path connected to said outlet of said liquid pump; wherein said outlet fluid path is in thermal contact with said accumulator so to allow said refrigerant flowing through said outlet fluid path to exchange heat with said accumulator.
