Document Type and Number:
WIPO Patent Application WO/2017/078333
Kind Code:
A1
Abstract:
Disclosed is a pipe freezing apparatus which, when a pipe leaks or is damaged, shuts off a flow of liquid by freezing a part of a pipe in order to repair or replace piping at a point where the leakage occurs. The pipe freezing apparatus comprises: a refrigerant inlet, formed on at least one of the first cover and the second cover, for introducing a refrigerant from the outside to the internal space thereof; and a refrigerant outlet for discharging the refrigerant from the inner space to the outside. The refrigerant flows into the internal space in a liquid state through the refrigerant inlet, is vaporized while exchanging heat with a fluid in the pipe in the internal space, and is discharged from the internal space through the refrigerant outlet. The present invention reduces the time and costs for maintaining or repairing pipes.
