[0022] In order to increase the heat exchange and dehumidification effect, fins 4 for enhancing heat exchange are installed in the interval between two adjacent parallel heat pipes 2.

[0023] In the present invention, a water pan 5 is installed outside the energy storage module 1, and the water pan 5 is located at the downstream end of the bottom of the casing 3 in the wind direction. The water pan 5 is connected to the drain pipe 8.

[0024] The utility model provides a ventilation and dehumidification device for effectively utilizing natural cold energy based on a heat pipe energy storage module, comprising an energy storage module 1, a heat pipe 2, a casing 3, an upper air valve 6 and a lower air valve 7; wherein the energy storage module 1 is used to store the coldness of cold air at night; the heat pipe 2 is used for heat transfer between cold air and the energy storage module and heat exchange between hot air and the energy storage module to achieve dehumidification of the air; the casing 3 is used to fix the relevant modules; the upper air valve 6 is used to control the on and off of cold air at night; the lower air valve 7 is used to control the on and off of hot air during the day; a motor transmission device can be further provided to control the on and off of the upper air valve 6 and the lower air valve 7; a water tray 5 can be further provided to receive and discharge condensed water generated by the hot air.

[0025] The utility model provides a ventilation and dehumidification device based on a heat pipe energy storage module that effectively utilizes natural cold energy. A specific use method is:

[0026] The dehumidification device provided by the utility model is placed in the main ventilation channel such as the ventilation tunnel or traffic tunnel of the pumped storage power station. When the temperature difference between day and night is large in summer, the hydropower station continues to ventilate through the main ventilation channel, and the temperature and humidity sensor is used to judge the temperature of the night ventilation. When the cold air temperature is lower than the average dew point temperature at 11 o'clock in the daytime of the previous three days, the upper air valve 6 is opened, and the lower air valve 7 is kept closed. The cold air enters the upper cavity of the casing of the dehumidification device and exchanges heat with the upper part of the heat pipe. At this time, the upper part of the heat pipe is the condensation section, and the middle part of the heat pipe, that is, the part that directly contacts the heat pipe perforation 9 of the energy storage module 1, is the evaporation section. That is, the heat of the energy storage material inside the energy storage module 1 causes the working fluid inside the heat pipe to evaporate and absorb heat in the evaporation section, and the working fluid inside the heat pipe releases heat to the cold air in the condensation section, thereby realizing the storage of cold energy of the energy storage module 1. When any temperature of the energy storage module 1 temperature or the cold air temperature is higher than the average dew point temperature at 11 o'clock in the daytime of the previous three days, the upper air valve 6 is closed to complete the cold storage process of the energy storage module 1.

[0027] Dehumidification process: The temperature and humidity sensor determines that the dew point temperature of daytime ventilation is higher than the temperature of the energy storage material of the energy storage module 1, opens the lower air valve 7, and maintains the upper air valve 6 in a closed state. The high-humidity hot air passes through the lower air valve 7 of the dehumidifier and enters the lower cavity of the casing inside the dehumidifier, and exchanges heat with the heat pipe. At this time, the lower part of the heat pipe is the evaporation section, and the middle part of the heat pipe, that is, the part that is in direct contact with the heat pipe perforation 9 of the energy storage module 1, is the condensation section. The high-humidity hot air exchanges heat with the evaporation section at the bottom of the heat pipe, and is evaporated by the working fluid in the heat pipe to absorb heat, cool down and dehumidify. The working fluid in the heat pipe exchanges heat with the energy storage material of the energy storage module 1 in the condensation section, condenses and releases heat, and then flows back to the evaporation section.

[0028] In this way, the cold energy of the cold air at night is used to dehumidify the hot and humid air during the day. The dehumidification device has low energy consumption and only requires a small amount of electricity to drive the air valve switch.

[0029] The utility model provides a ventilation and dehumidification device which effectively utilizes natural cold energy based on a heat pipe energy storage module. It utilizes the large temperature difference between day and night in cold areas in summer, uses energy storage materials to store cold energy at night, and is used to dehumidify air with high temperature and high humidity content during the day, which has the advantage of low energy consumption.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention.
