Example Embodiment
[0021] Specific implementation mode 1: Combination Figure 1 to Figure 4 To illustrate this embodiment, a high temperature heat pipe with an internal spring and spiral fins described in this embodiment, the high temperature heat pipe includes a tube shell 1;
[0022] The tube shell 1 is a cylindrical structure with closed ends;
[0023] The high temperature heat pipe also includes a capillary core 2, an internal spring 3 and a fin 4;
[0024] One end of the tube shell 1 is an evaporation section, and the other end of the tube shell 1 is a condensation section. Between the evaporation section and the condensation section of the tube shell 1 is an adiabatic section; wherein the heat source acts on the evaporation section of the tube shell 1, and the tube The condensation section of the shell 1 dissipates heat from the cold source;
[0025] The capillary core 2 is arranged on the inner side wall of the tube shell 1;
[0026] The interposing spring 3 has a helical structure and is arrange...
Example Embodiment
[0029] Embodiment 2: This embodiment further defines the high-temperature heat pipe with the helical fins of the interpolated spring described in Embodiment 1. In this embodiment, the interpolated spring 3 is made of high-temperature ceramic.
[0030] In this embodiment, the insert spring 3 is made of high-temperature ceramic. The high-temperature ceramic material has a high melting point and has the characteristics of high temperature resistance. It can adapt to the high temperature of the evaporation section of the shell 1 and the high-temperature ceramic material has good stability and is difficult to interact with the working fluid. The occurrence of chemical reaction or physical change ensures that the high-temperature heat pipe has stable heat transfer performance, so that the high-temperature heat pipe described in this embodiment has a long working life and the possibility of industrial application.
Example Embodiment
[0031] Embodiment 3: This embodiment further defines the high-temperature heat pipe with an internal spring and spiral fins described in Embodiment 1. In this embodiment, the fin 4 has a spiral structure.
[0032] In this embodiment, the helical structure of the fin 4 can strengthen the convection heat dissipation process of the condensation section of the tube shell 1 and reduce the flow resistance of the fluid during the heat dissipation process.
