Capillary copper tubes are copper tubes with extremely thin inner and outer diameters. They are widely used in household refrigerators, electric freezers, high-precision instruments, electronic equipment and instruments, etc. The material commonly used is high-quality copper such as TP2 and TU1, which has excellent thermal conductivity and corrosion resistance.
Application Scenarios
① Refrigeration system: Capillary copper tubes are widely used in small-sized Freon refrigeration devices with a capacity of less than 10KW. By changing the length and diameter, they can meet different working conditions and cooling capacity requirements;
② Gas transportation: Applicable to water cooling projects and environmental protection projects, etc.;
③ Daily life: In building water supply systems, capillary copper tubes are widely used due to their good thermal conductivity and high low-temperature strength.
