Description

technical field [0001] The invention relates to a heating device, in particular to a heat transfer mechanism of an internally separated gravity heat pipe. Background technique [0002] The heat pipe is a heat transfer element with high thermal conductivity, which transfers heat through the phase change of the working medium in the pipe. A typical heat pipe is composed of a tube shell, a liquid-absorbing core and an end cap. After the heat pipe is pumped into a high vacuum, it is filled with an appropriate amount of working fluid. One end of the tube is the evaporating section, and the other end is the condensing section, and an adiabatic section can be arranged between the two sections according to application requirements. When one section of the heat pipe is heated, the working fluid absorbs the latent heat of vaporization and evaporates, and the steam flows to the other end through the capillary wick under a small pressure difference, releasing the latent heat of vapori...

Problems solved by technology

The disadvantage of gravity heat pipes in plate shape or shapes other than tubes is that since the heat pipe cavity is integrated, the working medium at the evaporating end absorbs external heat energy, and at the same time it is in contact with the evaporating end of the device and passes through it. Dissipate heat to the material in the equipment, making it difficult for the working medium to quickly reach the evaporation temperature and evaporate. The start-up time of the heat pipe is very slow, and the material heating time is long, which prolongs the processing time

[0005] There is also a separate heat pipe, which is characterized by separating the evaporating end and the condensing end of the heat pipe, and connecting the upper part of the condensing end through the steam pipe on the upper part of the evaporating end, and the lower part of the condensing end The reflux pipe is connected to the lower part of the evaporating end, and the whole system is evacuated into a high vacuum and filled with working fluid, thus forming a separate heat pipe, which greatly improves the start-up time of the heat pipe, but its structure is relatively complicated, and the evaporating end needs to occupy additional space, and the equipment volume increase, making it more difficult
