Title:
HEAT PIPE TEMPERATURE MEASURING SLEEVE TUBE
Document Type and Number:
WIPO Patent Application WO/2016/074410
Kind Code:
A1
Abstract:
A heat pipe temperature measuring sleeve tube (300), installed on an inner wall of a reactor heat pipe (200) and arranged perpendicular to an axial direction of the heat pipe (200); one end of the heat pipe temperature measuring sleeve tube (300) distal from the inner wall of the heat pipe (200)is close-ended, and a water-intake hole (320) is provided on one side of the heat pipe temperature measuring sleeve tube (300) facing the water-inflow direction of the heat pipe (200), the water-intake hole (320) being in fluid communication with an inner hole (310) of the heat pipe temperature measuring sleeve tube (300); several water-intake holes (320) are axially arranged along the heat pipe temperature measuring sleeve tube (300), and several water-intake holes (320) are symmetrically arranged with respect to the axial-wise central portion of the heat pipe temperature measuring sleeve tube (300), and at least two water-intake holes (320) incline towards the axial-wise central portion of the heat pipe temperature measuring sleeve tube (300) in the inner-hole (310) direction. The heat pipe temperature measuring sleeve tube reduces the impact of the coolant water on a temperature measuring device, thus extending service life of the temperature measuring device, and improving temperature measurement accuracy.
