Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning condensers, and more specifically relates to an air-conditioning condenser cooling device. Background Art

[0002] The air conditioner condenser is a household air conditioner that is used for cooling. The heat exchanger (also called a heat exchanger) in the outdoor unit is called a condenser, while the heat exchanger in the indoor unit is called an evaporator. The heat release process of the condenser converts high-temperature and high-pressure gaseous Freon into low-temperature and high-pressure liquid Freon through heat exchange with the air outdoors. The air conditioner condenser consists of a fixed plate, fins, a U-shaped tube and a connecting U-tube. When assembling the air conditioner condenser, the U-shaped tube is inserted into the fin on the fixed plate and fixed. The connecting U-tube is welded between the two U-shaped tubes through welding technology to connect the two U-shaped tubes. The tube is then installed on the outdoor unit of the air conditioner. The Freon is cooled with the cooperation of the fan.

[0003] The inventor discovered in his daily work that when the air-conditioning condenser is being repaired, since the copper tubes are connected by welding, when the air-conditioning outdoor unit is working normally, the internal fan generates vibrations, which drive the copper tubes to vibrate, making the copper tube welding points easy to loosen and break. As a result, the maintenance workers need to find the broken points of the copper tubes, but usually they put the condenser tubes in water to find the broken points. The whole process is very cumbersome and affects the maintenance efficiency. Utility Model Content

When the fixing ring is further fixed, the No. 1 threaded block and the No. 2 threaded block are brought close together, and the No. 1 threaded block and the No. 2 threaded block are fixed by the fixing mechanism, thereby fixing the fixing ring to prevent the fixing ring from being offset due to the vibration of the fan in the air conditioner outdoor unit.

[0012] According to the air conditioner condenser cooling device described in the first embodiment of the utility model, the surfaces of the first thread block and the second thread block are both provided with threads, and the arc surface of the connecting U-tube is slidably connected with a thread cover. The thread cover is rotated so that the thread cover is rotated to the first thread block and the second thread block, thereby fixing the fixing ring.
