The invention relates to the field of refrigerator equipment, in particular to a fin evaporator leak detecting device. The fin evaporator leak detecting device comprises a leak detecting groove as well as an air inflation delayed control system, a sound-light alarm system and a pneumatic marking device which are arranged on the leak detecting grooves. A fin evaporator leak detecting method comprises the following steps of: firstly, clamping a quick joint; secondly, pressing down an air inflation button and introducing nitrogen into a fin evaporator tube by virtue of the air inflation delayed control system, and giving a sound-light alarm by the sound-light alarm system when pressure reaches a set value; thirdly, manually putting the fin evaporator and the quick joint into the leak detecting groove to be detected together; fourthly, after set leak detecting time is up, alarming and reminding by the sound-light alarm system, and manually taking out the fin evaporator from the leak detecting groove and then dismounting the quick joint clamped at a plugging end and an air inflation end of the fin evaporator for deflating and relieving pressure; and fifthly, marking. By virtue of the fin evaporator leak detecting device provided by the invention, product quality can be effectively guaranteed while efficient and quick production is realized.
Description
technical field [0001] The invention relates to the field of refrigerator equipment, and more specifically, to a leak detection device and a leak detection method for a finned evaporator. Background technique [0002] Common leak detection lines can be divided into two types, one is the air pressure leak detection line, and the other is the water bath leak detection line. Air pressure leak detection line is often used for leak detection of special items due to high sensitivity requirements and high cost. Water bath leak detection is not only intuitive, high-speed, and accurate detection of small product leakage, but also low cost. It is the main form of leak detection in today's industrial production. The traditional water-bath fin evaporator leak detection line has the following defects: first, the drainage efficiency is low, it is inconvenient to change the water, and it is easy to cause secondary pollution of the product; second, the leak detection time and inflation pre...
