Leak detection tooling case and leak detection method thereof

Abstract

The invention provides a leak detection tooling case used for detecting the leak of a heat exchanger. The leak detection tooling case comprises a case body used for accommodating the heat exchanger; the side of the case body is provided with a movable door used for sealing the case body, the movable door is provided with a first detection hole used for allowing a detection probe to penetrate and a detection hole opening device used for opening the detection hole, and the case body is provided with a connecting device communicating the interior and exterior of the case body. The invention further provides a leak detection method. The leak detection tooling case has the advantages that the generality is high, cost is low, operation is simple, and maintenance is facilitated; the leak detection method has the advantages that the producing efficiency is high, and the safety and reliability are provided; the leak detection rate and alarm point meet the accuracy required by a helium detection machine.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a leak detection tool box and a leak detection method thereof. Background technique [0002] Microchannel heat exchanger is a new type of high-efficiency heat exchanger, which has the advantages of high heat transfer efficiency, small size, light weight, and less charge. It has been widely used in household and commercial refrigeration equipment, but there are also welding positions More often, the product welding process needs to be carried out in a brazing furnace, and the intermediate process cannot be monitored throughout. The only way to reduce leakage is through production assembly and adjustment of welding parameters, and inspection control is carried out through helium detection. At present, the helium inspection machine is used for production inspection, and the inspection is carried out by vacuumizing the whole box. As the size of the product increases, the volume of the...

AI Technical Summary

Problems solved by technology

As the size of the product increases, the volume of the leak detection box and the evacuation time increase significantly, which seriously affects the efficiency of product leak detection

Moreover, the purchase cost of the helium detector is relatively high. When the product leaks, it is impossible to determine the specific location of the leak, and corresponding measures cannot be taken to improve it.
