Heat pipe structure based on solar thermochemical adsorption refrigeration and frozen soil protection method
The invention provides a heat pipe structure based on solar thermochemical adsorption refrigeration and a frozen soil protection method, the heat pipe structure comprises a heat pipe, the heat pipe is of an internally sealed U-shaped hollow structure, and a refrigeration working medium is arranged in the heat pipe; the heat pipe comprises a high-temperature adsorption bed, a condensation section, an evaporation section and a low-temperature adsorption bed which are communicated in sequence; the high-temperature adsorption bed is filled with a high-temperature adsorbent and is used for desorbing the refrigerant under the heating action of solar energy to obtain a high-temperature refrigerant; the condensation section is vertically arranged and is used for condensing the high-temperature refrigeration working medium to obtain a condensed refrigeration working medium and enabling the condensed refrigeration working medium to enter the evaporation section under the action of gravity; the evaporation section is transversely arranged and is used for evaporating the condensed refrigerant under the heating action of the frozen soil temperature and the adsorption action of the low-temperature adsorbent to obtain the evaporated refrigerant; and the low-temperature adsorption bed is filled with a low-temperature adsorbent for adsorbing the evaporated refrigerant. According to the scheme, the cooling effect of the heat pipe on frozen soil and the heat stability of the heat pipe are improved.
