Description

Technical Field

[0001] The utility model relates to the technical field of air cooling unit protection, and more specifically, to an antifreeze device for an air cooling unit. Background Art

[0002] In colder areas, air-cooled units need to be antifreeze operated. During low-load operation in winter, people are arranged on site to continuously measure the temperature, and the remote (control room operator) continuously adjusts the frequency and forward and reverse rotation of the air-cooling fan to ensure the normal temperature of the heat sink. The antifreeze device for air-cooled units in high-cold areas described in the publication number (CN213543268U) is installed at each cooling unit, that is, at the air inlet of the wind tube at the bottom of the cooling triangle, and arranged horizontally. The arrangement should not affect the air flow in the unit, and the air supply resistance of the system should not be increased or added. The air flow characteristics of the ACC system should be fully considered in terms of selection and layout. While greatly increasing the antifreeze effect, the original air resistance should be reduced as much as possible, and the resistance of the air supply system should not be increased due to the influence of the antifreeze device. After the arrangement is completed, when antifreeze is needed, start the motor, the motor drives the rotating shaft and the drum to rotate, and then drives the wire transmission rope, the wire transmission rope drives the slide rail eye frame to slide, and then makes the transmission beam and tarpaulin slide, and covers the heat dissipation unit for antifreeze. After the antifreeze is completed, when the air-cooling unit needs to run, start the motor to reverse, the rotating shaft, the drum and the wire transmission rope drive the transmission beam and the tarpaulin to reverse, exposing the heat sink of the air-cooling unit.

[0003] When the above device is in use, the shutter structure composed of the transmission beam and the tarpaulin can be closed on the spot when the air-cooling unit needs to be protected from freezing, ensuring that cold air no longer enters the heat sink. The antifreeze efficiency is high and the effect is good. However, the louvered tarpaulin has poor sealing performance and is prone to damage and closing failures during use. In severe weather, the antifreeze effect of the air-cooling unit will be deteriorated. Utility Model Content
