Abstract

A system including: a temperature responsive polymer configured to expand to a cross-sectional area of a fluid channel when a temperature of the fluid in the fluid channel is greater than or equal to a temperature threshold T, and to retract to less than the cross-sectional area when the temperature of the fluid in the fluid channel is less than T, an expandable material layer surrounding the temperature responsive polymer and configured to expand and retract with the expansion and retraction of the temperature responsive polymer, and a sieve housing encasing the expandable material and being configured to be disposed in the fluid channel, wherein when the temperature of the fluid in the fluid channel is greater than or equal to T, the temperature responsive polymer expands to the cross-sectional area such that the expandable material layer prevents the fluid in the fluid channel from passing through the sieve housing.
