Abstract

The invention discloses a high-temperature heat pipe wick heat transfer limit experiment device and method. The device comprises an upper sealing plate, a heating plate, a lower sealing plate, a left liquid sealing plate, a left gas sealing plate, a right liquid sealing plate, a right gas sealing plate, a pressing plate, a wick sample, a gas preheater, a first gas storage chamber, a first servo pump, a second gas storage chamber, a second servo pump, a working medium storage chamber, a vacuum pump unit, a pressure difference transmitter, a valve and the like. According to the invention, experimental research on the heat transfer limit of the wick of a high-temperature heat pipe can be realized, and visual research on the heat transfer limits such as capillary limit, entrainment limit and boiling limit of the high-temperature heat pipe can be obtained.

Description

technical field [0001] The invention relates to the technical field of phase-change heat equipment, in particular to a heat transfer limit experimental device and method for a liquid-absorbing core of a high-temperature heat pipe. Background technique [0002] The heat pipe is a passive heat transfer device that utilizes the phase change of the working fluid to transfer heat. It has the advantages of simple structure and passive. The working medium in the heat pipe works in the sealed shell cavity, which is difficult to observe through visual means, especially the high-temperature heat pipe uses liquid metal as the working medium, which is even more difficult to observe directly. The heat transfer limit puts restrictions on the heat transfer capacity of the heat pipe, such as capillary limit, entrainment limit, boiling limit, etc., which greatly limit the heat transfer power of the heat pipe, and may even lead to the failure of the heat pipe.
