DETAILED DESCRIPTION

[0018] The utility model will be further explained in detail in connection with the drawings and examples.

If it is in the north, the ice 9 can be the ice block collected from river or lake in winter, the ice 9 can also be the artificial broken ice of winter. The volume of ice storage 1 can be determined according to the mine cold quantity, the volume of ice storage 1 is large, and the larger the storage ice block quantity is, the more favorable for the low-temperature storage of ice block, can effectively reduce the energy consumption. Generally for medium and large mines, the ice storage with the length of 40 meters, the width of 50 meters and the depth of 20 meters can be designed, or be designed according to the requirement.

[0020] The cold exchange component 2 is composed of cold exchange chamber 2-1 and fan 2-2, the serpentine pipe 2-3 is arranged in the cold exchange chamber 2-1, and the heat exchange fin is arranged on the serpentine pipe 2-3; the air outlet of fan 2-2 is connected with the air inlet of cold exchange chamber 2-1, and the air outlet of cold exchange chamber 2-1 is connected with mine air inlet pipe 3. The serpentine pipe 2-3 is a water pipe that is coiled in the cold exchange chamber in a serpentine shape, and the purpose is to increase the length of the pipe to maximize the cold exchange. The heat exchange fin is a uniformly arranged metal sheet attached to the surface of the serpentine pipe 2-3, which can be arranged perpendicular to the axis of the serpentine pipe 2-3 to increase the cold exchange surface area and thus improve the heat transfer efficiency. The metal sheet can be annular.

[0021] The water inlet end of the serpentine pipe 2-3 is connected with the water outlet 1-5 through the first water pipe 4, the water outlet end of the serpentine pipe 2-3 is connected with the water inlet 1-4 through the second water pipe 5, the first water pump D1 is arranged on the first water pipe 4, the second water pipe 5 can be connected with a water diversion pipe, the water diversion pipe is connected with a water source, and can be used as a starting water source for melting when the ice in the ice storage starts to melt. Of course, it can also wait for the water naturally melted by the ice at the upper part of the ice storage to perform a cooling cycle. As the ice melts more and more during the cycle, the water quantity will become larger and larger. A water discharge pipe and a water inlet valve can also be connected to the second water pipe 5, and water can be discharged when needed. The water diversion pipe can also be separately arranged, that is, the water diversion pipe is directly connected with the water inlet 1-4.

[0022] After water is injected into the ice storage 1, the upper surface of the ice block and the water level gradually decrease as the water gradually circulates and melts the ice block. Therefore, the water outlet can be designed in the following way:
