Description

Technical Field

[0001] The utility model relates to the technical field of processing air-conditioning condenser pipes, in particular to a clamping tool for the elbow of an air-conditioning condenser pipe. Background Art

[0002] When the air conditioner is cooling, the heat exchanger (also called a heat exchanger) in the outdoor unit is called the condenser, while the heat exchanger in the indoor unit is called the evaporator. The condenser releases heat, exchanging heat with the outdoor air to convert high-temperature, high-pressure gaseous Freon into low-temperature, high-pressure liquid Freon.
