Embodiment 1
[0037] Refer to the attached Figure 1-3 Hereinafter, the anti-pressure and torsion protection support frame of the gravity type heat pipe according to the embodiment of the present invention will be described. It includes a one-way heat-conducting rubber sleeve 8, a protective steel plate 5, a spring 7, a heat-conducting rubber 6 and a fixing piece.
[0038] The one-way heat-conducting rubber sleeve 8 is used to tightly fit the heat dissipation section of the gravity heat pipe 9. The upper section of the wrapping sleeve is made of heat-conducting rubber, and the lower half section is made of heat-insulating rubber. Thermally conductive rubber6. The one-way heat-conducting rubber sleeve 8 puts half of the heat-conducting rubber close to the pavement layer 10 , so that the heat of the heat pipe can be gathered and conducted to the pavement layer 10 . At the same time, the one-way heat-conducting rubber sleeve 8 wraps the heat pipe cooling section tightly, so that more heat fr...
Embodiment 2
[0044] Refer to the attached Figure 1-3 The snowmelting system for the anti-pressure and twist protection support of the gravity heat pipe according to the embodiment of the present invention will be described, including the highway, the gravity heat pipe 9, and the support frame for the anti-pressure and twist protection of the gravity heat pipe in Embodiment 1.
[0045] Wherein, the expressway includes a pavement layer 10 , a road base layer 11 and a soil layer 12 sequentially from top to bottom.
[0046] The gravity heat pipe 9 (or ground temperature heat pipe) includes an evaporation section, an adiabatic section and a heat dissipation section. The heat pipe is vacuum-sealed for low-boiling liquids such as liquid ammonia and freon. The evaporation section heats the working medium to evaporate into gas by absorbing heat. The gas rises along the tube to the heat dissipation section. Heat exchange occurs on the tube wall.

[0053] This embodiment also discloses the construction method of the gravity heat pipe anti-pressure torsion protection support road snow melting system described in embodiment 2, wherein the gravity heat pipe 9 includes a vertical section and a horizontal section, the evaporation section is located below the vertical section, and the heat dissipation section is located at For the upper part of the vertical section and the horizontal section, the construction steps are as follows:
[0054] (1) by the heat dissipation effective area of the heating heat pipe (gravity heat pipe 9), calculate the effective snow-melting working area of the gravity heat pipe 9 (relying on field test data calculation), and determine the distance between two adjacent rows of gravity heat pipes 9;
[0055] (2) boreholes are carried out on the road at the vertical section of the designated gravity heat pipe 9, and the hole is deep to the constant temperature layer of the earth;
[0056] (3) Set the ...
