The annular and separation device loop circuit heat pipe that spacing changes in a kind of short transverse
Technical field
The invention belongs to heat pipe field, more particularly to a kind of heat exchange heat pipe.
Background technology
Hot pipe technique is George Ge Luofo of U.S. Los Alamos (Los Alamos) National Laboratory in 1963 One kind of (George Grover) invention is referred to as the heat transfer element of " heat pipe ", and it takes full advantage of heat-conduction principle and is situated between with phase transformation The heat of thermal objects, is delivered to outside thermal source rapidly by the quick thermal transport property of matter through heat pipe, and its capacity of heat transmission, which exceedes, appoints The capacity of heat transmission of what known metal.
The industries such as aerospace, military project are widely used in before hot pipe technique, since being introduced into radiator manufacturing so that People change the mentality of designing of traditional heat sinks, have broken away from the high air quantity motor of simple dependence to obtain the list of more preferable radiating effect One radiating mode, using hot pipe technique so that radiator obtains satisfied heat transfer effect, opens radiating industry new world.At present Heat pipe is widely used in various heat transmission equipments, including nuclear power field, such as the UTILIZATION OF VESIDUAL HEAT IN of nuclear power.
On the one hand, heat pipe is in evaporation process, and inevitably carrying of liquids is in tedge, simultaneously as condensation end Exothermic condensation so that there is liquid in condensation end, liquid also inevitably enters tedge, so that tedge Interior fluid is liquid-vapor mixture, while the on-condensible gas that heat pipe can be produced because of aging in the process of running, on-condensible gas one As rise to the condensation end on heat pipe top, the presence of on-condensible gas causes the pressure in condensation end of heat pipe to increase, and pressure causes Liquid ramps up Bottomhole pressure.It greatly have impact on the efficiency of heat exchange.
