Abstract

A related adjustable and controllable apparatus for measuring heat transfer efficiency of a gravity heat pipe is characterized in that in the structure, an upper temperature-control barrel and a lower temperature-control barrel are both connected with a cold bath and performs independent temperature control respectively on a condensing segment and an evaporation segment of the gravity heat pipe; through cooperation of a support of the support, a hand-operated winch with a brake, a hoisting frame, a steel strand and a clinometer, accurate control on the inclined angle of the gravity heat pipe is realized; temperature sensors are arranged on the surfaces, in the upper and the lower temperature-control barrels, of the gravity heat pipe and in a cold bath solution, and hot-fluid sensors are distributed on the surface of the gravity heat pipe; and measuring data of the temperature sensors and the hot-fluid sensors are automatically acquired through a data collector and a computer. The apparatus is capable of freely adjusting the inclined angle of the gravity heat pipe in the scope of 0 DEG-90 DEG, thereby realizing accurate measuring of the heat transfer efficiency of the gravity heat pipe at different inclined angles, and providing test basis and technology parameters for fully giving play the engineering efficiency of the gravity heat pipe.

Description

technical field [0001] The invention relates to an experiment testing device, in particular to an adjustable gravity heat pipe heat transfer efficiency testing device. It can effectively measure the heat transfer efficiency of gravity heat pipes under different working conditions such as structure, working fluid, liquid filling amount and inclination angle, and provide test basis and technical parameters for fully exerting the engineering performance of gravity heat pipes. Background technique [0002] A heat pipe is an efficient heat transfer element, and its working principle is mainly to use the evaporation and condensation of its internal working fluid to realize heat transfer. Heat pipe technology has a wide range of applications in space exploration, cold area engineering, industrial engineering, and medical treatment. Surgical instruments and many other aspects. [0003] Gravity heat pipe, also known as two-phase closed thermosiphon, is a kind of heat pipe widely us...
