A radiator core leak detection tool

Abstract

The invention is applicable to the field of air tightness detection devices, and provides a leak detection tool for radiator cores, which includes an air charging port on the periphery of the rotating core pipe, first threads on the upper and lower sides of the air charging port; one end of the rotating core pipe The ring is provided with a number of core tube positioning blocks; the inner wall of the rotating sealing sleeve is provided with threads; the rotating sealing sleeve is screwed outside the rotating core tube, and the periphery of the rotating sealing sleeve is provided with a first air guide port; the airbag support sleeve is sleeved outside the rotating sealing sleeve, and the airbag supports The outer wall of the sleeve is provided with a second air guide port; the outer wall of the airbag support sleeve is provided with an airbag installation groove; The tightening effect is good, and the inlet of the radiator core pipe with a small diameter can be sealed. By putting the dry air bag deep into the pipe inlet, and then inflating the air bag and the inside of the radiator core in turn, the sealing effect of the device is good at the same time. Compact structure.

Description

technical field [0001] The invention relates to the field of air tightness detection devices, in particular to a radiator core leak detection tool. Background technique [0002] The radiator core is the main part of the radiator. The radiator core is generally assembled by fins, partitions and seals. The partitions and fins are arranged in sequence, and the fluid passes through the fins to dissipate heat. After the radiator core is assembled, the airtightness of the radiator core needs to be tested. [0003] In the prior art, when the radiator core is tested, a certain pressure of gas is usually passed into the radiator core, and then the radiator core is put into the water, and the leakage of the radiator core will generate air bubbles in the water , use air bubbles to judge the location of the leak of the radiator core. [0004] In the prior art, the clamping effect of the tooling used for water inspection is poor; [0005] At the same time, the plugging method used in ...

AI Technical Summary

Problems solved by technology

[0006] However, due to the small diameter of the inlet of the radiator core pipe, the inflated air bag cannot be inserted into the inlet of the radiator core pipe. If the air bag is deflated, the amount of gas in the air bag cannot be adjusted. Control, too much air release may affect the sealing effect of the plug

[0007] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
