According to an aspect of the present application, there is provided an in-cooler leak detection apparatus, and fig. 1 is a block diagram showing an in-cooler leak detection apparatus according to an embodiment of the present application, and is described in detail as follows:
Referring to fig. 1, according to an aspect of the embodiment of the present application, there is provided an in-cooler leakage detection apparatus, which includes a flow cell 20, a first humidity probe 31, a second humidity probe 41, a first hygrometer 30, a second hygrometer 40, and a PLC controller 50.
And a flow cell 20, one end of which is connected to the outlet of the cooler 10 by a pipe, and the other end of which is provided with an exhaust valve 21, wherein the gas flowing out from the outlet of the cooler flows into the flow cell 20, and the gas is discharged through the exhaust valve 21 after filling the flow cell 20.
The first humidity probe 31 is externally arranged in the outside air, and is used for detecting the humidity information of the air and sending out detection information.
The second humidity probe 41 is built in the flow cell 20, and detects humidity information of the gas in the flow cell 20, and transmits the detected information.
The first hygrometer 30 is electrically connected to the first humidity probe 31, and is configured to receive detection information of the first humidity probe 31 and output environmental humidity information.
The second hygrometer 40 is electrically connected to the second humidity probe 41, and is configured to receive the detection information of the second humidity probe 41 and output the test humidity information.
The PLC controller 50 is electrically connected to the first hygrometer 30 and the second hygrometer 40, and is configured to receive the environmental humidity information and the test humidity information, and determine that the cooler 10 leaks if the real-time difference between the test humidity and the environmental humidity is greater than a preset value.
In the present application, the flow cell 20 serves to temporarily store the gas discharged from the cooler 10, and after the flow cell 20 is filled with the gas, the gas is discharged through the gas discharge valve 21, so that the gas in the flow cell 20 is kept filled and in circulation, that is, the gas in the flow cell 20 can reflect the physical characteristics of the gas discharged from the cooler 10 in real time.
The first hygrometer 30 detects the humidity in the outside air by the first humidity probe 31 and stores the humidity as the ambient humidity, and the air flowing in the cooler 10 is also introduced by the air, and the ambient temperature detected by the first humidity probe 31 can reflect the humidity of the air introduced into the cooler 10.
The second hygrometer 40 detects the humidity of the gas in the flow cell 20 by means of the second humidity probe 41 and stores it as a test humidity.
After receiving the information of the environmental humidity and the test humidity sent by the first hygrometer 30 and the second hygrometer 40, the PLC controller 50 calculates and stores the difference between the test humidity and the environmental humidity as a real-time difference value, compares the real-time difference value with a preset value, determines that the cooler 10 has no internal leakage if the real-time difference value is smaller than the preset value, determines that the cooler 10 has internal leakage if the real-time difference value is larger than the preset value, stops and maintains in time, thereby improving the cooling efficiency of the cooler 10, avoiding excessive moisture in gas, corroding the cooler 10 and other equipment of the unit, and improving the service lives of the cooler and the whole unit.
It should be emphasized that the preset value varies according to factors such as the use environment and season, and can be obtained according to a limited number of tests by taking a test difference value from no internal leakage to internal leakage of the present cooler 10 as a budget value.
In one embodiment of the application, the device further comprises a filter 60, the filter 60 being arranged between the flow cell 20 and the outlet of the cooler 10, the filter 60 and the flow cell 20 being in fluid communication via a conduit for filtering impurities in the gas.
In the present application, the impurities such as dust and gravel are filtered by the filter 60 before the gas discharged from the cooler 10 enters the flow cell 20, so that the impurities are prevented from adhering to the second humidity probe 41, and the detection efficiency and the accuracy of the detection data of the second humidity probe 41 are improved.
In one embodiment of the present application, the apparatus further comprises a flow meter 70, the flow meter 70 being disposed between the flow cell 20 and the outlet of the cooler 10, the flow meter 70 and the flow cell 20 being in fluid communication via a conduit for indicating the flow rate of the gas exiting the cooler 10 into the flow cell 20.
In the present application, the flow meter 70 visually checks the flow rate of the gas entering the flow cell 20 from the outlet of the cooler 10, and a smooth flow rate of the gas is advantageous for ensuring the stability of the detection by the second humidity probe 41.
In one embodiment of the application, the filter 60 is disposed at the forward end of the flow meter 70.
In the present application, after the gas comes out from the outlet of the cooler 10, the impurity is removed from the gas through the filter 60, and then the gas passes through the flowmeter 70, so that the service life of the flowmeter 70 can be improved.
In one embodiment of the present application, the flow meter 70 is a floating ball flow meter 70.
In the present application, the flow rate of the gas from the outlet of the cooler 10 to the flow cell 20 does not need to be precisely controlled, and only the smooth flow state of the gas in the flow cell 20 is ensured, so that the floating ball type flowmeter 70 can intuitively judge whether the flow rate of the gas is smooth.
In one embodiment of the present application, the PLC controller 50 is connected to an audible and visual device, and if the PLC controller 50 determines that the cooler 10 is leaking, a signal is output to the audible and visual device, and the audible and visual device outputs an alarm sound and illumination.
In the present application, if the PLC controller 50 determines that the cooler 10 is leaking, the acousto-optic device sounds an alarm and illuminates in time, so that an operator can find and process in time, and the working efficiency is improved.
In one embodiment of the present application, the PLC controller 50 is connected to a host computer, which displays the test humidity, the ambient humidity, and the real-time difference value in real time.
In the application, the upper computer can change the preset value according to the use environment, seasons and other factors of the cooler 10, and operators can check the test humidity, the environment humidity and the real-time difference value in real time, so that the working efficiency is improved.

The first humidity probe 31 detects the ambient humidity in the outside air, and the second hygrometer 40 bronze drum European first humidity probe 31 obtains the ambient humidity in the outside air. The PLC controller 50 receives the real-time difference between the test humidity and the ambient humidity from the first hygrometer 30 and the second hygrometer 40, and determines the magnitude of the real-time difference and the preset value, if the real-time difference is greater than the preset value, it indicates that the test humidity is too high, and internal leakage is generated in the cooler 10, so that the internal leakage is timely processed, and the influence on the service efficiency of the cooler 10 and the service life of the unit are avoided.
