APPARATUS FOR MANUFACTURING AN HEAT SHRINKABLE TUBE BY USING THERMOELECTRIC ELEMENT

摘要

An expanding apparatus of manufacturing a heat shrinkable tube using a thermoelectric element is provided to improve the cooling efficiency thereof by using a cooling unit including the thermoelectric element. An expanding apparatus(100) of manufacturing a heat shrinkable tube suing a thermoelectric element comprises an expansion pipe unit(110) and a cooling unit(120). A heated tube wire rod is expanded by negative pressure while passing through a pipe in the expansion pipe unit. The cooling unit includes the thermoelectric element and is disposed around the expansion pipe unit to cool off the expansion pipe. The expansion pipe unit includes a vacuum hole formed along a length direction of the expansion pipe unit.
