step C-C: when the shot picture is inconsistent with the picture input in advance, the air tightness of the surfaces of the hot fluid cavity 19 and the heat exchanger 15 is poor, air leakage occurs, and at the moment, a signal is transmitted to the warning sub-module to inform workers that the air tightness effect of the surface of the heat exchanger 15 is poor, so that the workers can repair the air tightness conveniently;

step D-b: at the moment, the state of the heat inlet fluid port 14 is shot in real time through the camera 26, the shot picture is transmitted to the receiving submodule in real time, and the shot picture is compared with a picture input in advance in a comparison unit in the analysis submodule;
step D-c: when the compared photos are consistent, the bundle tube 18 is in a sealed state, and when the compared photos are inconsistent, the analysis submodule judges that bubbles in the heat inlet fluid port 14 indicate that the air tightness of the bundle tube 18 is poor, and then a signal is transmitted to the warning submodule to inform workers that the air tightness effect of the surface of the bundle tube 18 is poor, so that the workers can conveniently repair the bundle tube;
the air tightness of the outer surface of the heat exchanger 15 and the inner beam tube 18 can be detected through the steps, when the air tightness of the outer surface of the heat exchanger 15 and the inner beam tube 18 is good, the air tightness of the heat exchanger 15 is detected to be qualified, the heat exchanger can be moved out of the detection pool 1, when one of the air tightness of the outer surface of the heat exchanger 15 and the inner beam tube 18 is not good, a warning submodule can give an alarm to a worker, the air tightness of the part of the heat exchanger 15 can be known to be poor, the worker can conveniently find the corresponding part for repair, meanwhile, the air tightness inside and outside the heat exchanger 15 is detected, and the working efficiency of detecting the air tightness can be improved;
example three:
when the heat exchanger 15 is detected, the heat exchanger 15 is moved out of the detection pool 1, the heat exchanger 15 is further clamped and enters the detection pool 1 for detection, and the operation is repeated, so that the liquid in the detection pool 1 becomes turbid gradually, and the judgment of air tightness in the second embodiment is influenced;
therefore, the basic structure of the present embodiment is the same as that of the second embodiment, and the following contents are added:

step two: judging the brightness of the illumination received by the illumination receiving plate through the judgment sub-module so as to judge the turbidity in the liquid;
the second step comprises the following specific operation steps:
step two-a: setting the illumination brightness to be a first level, a second level and a third level according to the requirements of workers in the judgment sub-module, wherein the brightness of the first level is high brightness, the brightness of the second level is medium brightness, and the brightness of the third level is low brightness;
step two-b: the illumination receiving plate transmits the signal to the judging submodule to be compared with the set illumination brightness, when the brightness received by the illumination receiving plate corresponds to the first-level brightness, the fact that the turbidity of the liquid in the detection pool 1 is not high is represented, and the airtightness of the heat exchanger 15 can be continuously detected;
step three-c: when the brightness received by the illumination receiving plate corresponds to the secondary brightness, the turbidity of the liquid in the detection pool 1 is indicated to be a medium level, and due to the influence of the turbidity of the liquid, bubbles generated on the surface of the heat exchanger 15 cannot be completely shot by the camera 26, and at the moment, the adjusting unit in the judgment submodule transmits a signal to the first pump body 32 to increase the air pressure pumped out by the first pump body 32;
if the air tightness of the heat exchanger 15 is low, bubbles are generated on the surface of the heat exchanger 15, and the air pressure entering the heat exchanger 15 or the air pressure in the bundle tube 18 is increased due to the increase of the air pressure pumped out by the first pump body 32, so that the speed of the bubbles generated on the surface of the heat exchanger 15 is increased, the bubbles generated in the liquid are obvious, the bubbles in the liquid are easily shot by the camera 26, and therefore, the step D can be repeated to continuously judge the air tightness of the heat exchanger;
step three-d: when the brightness received by the illumination receiving plate corresponds to the three-level brightness, the turbidity of the liquid in the detection pool 1 is high, the work of detecting the air tightness of the heat exchanger 15 cannot be carried out, and the liquid in the detection pool 1 needs to be replaced, so that the mobile control system is suspended, and the heat exchanger 15 is stopped being clamped to enter the detection pool 1;
the judgment sub-module transmits the signal to the second switch sub-module, the water suction pump 35 is turned on, liquid in the detection pool 1 is discharged through the water outlet pipe 3, when the liquid is completely discharged, the second switch sub-module is controlled to be turned off, the first switch sub-module is controlled to be turned on at the moment, the liquid pump is started to be turned on, external liquid is pumped into the detection pool 1 through the water inlet pipe 34, and when the liquid level reaches a specified position, the first switch sub-module is controlled to turn off the liquid pump;
