Compared with the traditional heat conduction pipe installation mode, the installation mode saves the installation space and is convenient to install.
The working principle of the heat conduction pipe is as follows: the glass vacuum tube 7 absorbs solar energy and converts the solar energy into heat energy which is transmitted to the heat conduction tube through the heat absorption fin 6. The heat transfer medium is liquid in the initial state, absorbs heat in the heat absorption section 1 and is evaporated into gas, and the gas heat transfer medium rises to the condensation section 3 through the inclined section 2. The gaseous heat exchange medium releases heat in the condensation section 3 and condenses into a liquid state, and the released heat is used for heating cold water in the heat storage water tank 8. The liquid heat exchange medium flows through the inclined section 2, and gravitational potential energy generated by the height difference is converted into kinetic energy, so that the heat exchange medium flows back to the heat absorption section 1.
