Problems solved by technology

[0004] Alkali metal heat pipes, AMTEC and other devices have internal circulating fluids that are chemically extremely active alkali metals. Therefore, for such devices, not only the materials used for each component of the device are required to have strong corrosion resistance, but also the inside of the device must be high vacuum, which is harmful to the working environment. The purity of the working medium is very high, and the filling of the working medium must be successful once, otherwise it may lead to the scrapping of the whole part of the device

Abstract

The invention aims at providing an alkali metal vacuum injecting device. The alkali metal vacuum injecting device comprises a mechanical pump, a molecular pump, a gas charging valve, a cylinder, a storage tank, a heating device, a measuring section and a tester, wherein the mechanical pump is connected with the molecular pump, the molecular pump is provided with the cylinder, the gas charging valve is arranged on the cylinder, the storage tank is connected with the cylinder, the heating device is arranged on the storage tank, the tester is connected with the cylinder by virtue of a pipe, and the tester is also connected with the storage tank by virtue of the measuring section. By adopting the alkali metal vacuum injecting device provided by the invention, the characteristic that alkali metal is active is overcome, the alkali metal injected into a device is guaranteed to be pure, and the requirement of the interior of the device to vacuum degree is met, thus the operating requirements of the device are met and the device is ensured to operate normally.

Description

technical field [0001] The invention relates to a device for active metal injection. Background technique [0002] The heat pipe is a high-efficiency heat transfer element that transfers heat by repeated phase changes (evaporation and condensation) of the working medium in the closed tube. It has small temperature difference between the evaporation section and the condensation section, large phase change latent heat, simple structure, and no moving parts. It is a promising new heat transfer technology at present. According to the working temperature of the heat pipe, the heat pipe can be divided into low temperature heat pipe (-273-0°C), normal temperature heat pipe (0-250°C), medium temperature heat pipe (250-450°C), high temperature heat pipe (450-1000°C), etc. . Alkali metal heat pipes are high-temperature heat pipes, which can withstand very high temperatures, but the internal pressure is very low, but the production conditions are relatively harsh. The pipes must be m...
