10. An active heat dissipation method for a 5G communication network base station, comprising the apparatus of any one of claims 1 to 9, characterized by the following steps:
s1, cooling the installation chamber (3) by the refrigerating end of the refrigerating sheet (2); the refrigerating fluid absorbs the heat of the heating end of the refrigerating sheet (2) to form a certain evaporation capacity; the pressure sensor monitors the evaporation capacity, the temperature sensor monitors the working temperature of the base station, and the monitoring result is sent to the controller;
s2, when the pressure value exceeds the set threshold value, the controller sends a signal to the air compressor (6) to start the air compressor, and the air compressor supplies air to the liquid storage space through the air pipe (5), mixes the air with steam to form air flow, passes through the air channel, enters the condensation pipe (9) and moves upwards; steam is condensed and falls down in the moving process, returns to the liquid storage space through the return pipe (10), and hot air flows out of the top of the condensing pipe (9);
s3, the air circulation piece (11) is matched with the adjusting piece in the condensation process, the lead screw (15) rotates to drive the mounting seat (16) to move up and down, the gear (19) is meshed with the rack (20), the fan (17) moves up and down and moves horizontally at the same time to dissipate heat of the condensation pipe (9) and the mounting box (1), and hot air flows out of the first heat dissipation port (13);
s4, when the temperature value exceeds the set threshold value, the controller controls the opening and closing piece, the electromagnet (28) is electrified, the metal block (24) is adsorbed, the moving frame (25) and the sealing plate (23) synchronously move upwards, the second heat dissipation opening (12) is opened, and hot air in the mounting chamber (3) overflows from the top.
