[0033] Please refer to Figure 1 and Figure 2 , this embodiment provides a pipeline air tightness detection device 100, the pipeline air tightness detection device 100 includes a pressurized air pump 110, a first connecting component 120, a second connecting component 130 and an air pressure detection component 140;

[0034] The first connection assembly 120 is configured with at least one first pipe joint 121, and the second connection assembly 130 is configured with at least one second pipe joint 131, and the first pipe joint 121 and the second pipe joint 131 are respectively used to connect with the coolant pipeline 10 to be tested;

[0035] One of the first pipe joint 121 and the second pipe joint 131 is connected to the pressurized air pump 110 , and the air pressure detection component 140 is connected to the first pipe joint 121 or the second pipe joint 131 to detect the pressure in the coolant pipeline 10 to be tested.

[0036] Please refer to Figure 1 and Figure 2 The working principle of the pipeline air tightness detection device 100 is:

[0037] The function of the pipeline air tightness detection device 100 is to perform air tightness detection on the relevant pipelines constituting the fan cooling system before assembling the fan cooling system, so as to avoid the situation that the air tightness of the relationship to be assembled does not meet the requirements, thereby effectively reducing the situation that the cooling system of the fan leaks coolant due to the relationship air tightness not meeting the requirements, thereby effectively exposing the probability of the fan leaking coolant to leakage, thereby effectively ensuring the cleanliness of the fan during operation, preventing it from being contaminated by the leaked coolant, and thereby extending the cleaning cycle of the fan to ensure the normal operation of the fan;

[0038] Specifically, when the pipeline air tightness detection device 100 is used to perform air tightness detection on the relationship, the two ends of the coolant pipeline 10 to be tested are respectively connected to the first pipe joint 121 and the second pipe joint 131, and then, pressurized gas is injected into the coolant pipeline 10 to be tested through the first pipe joint 121 or the second pipe joint 131 connected to the pressurized air pump 110, and then after the air pressure in the coolant pipeline 10 to be tested reaches the test air pressure, it is subjected to pressure maintenance detection. Thus, it can be judged whether the air tightness of the coolant pipeline 10 to be tested meets the use requirements according to the situation of injecting pressurized gas into the coolant pipeline 10 to be tested and the pressure maintenance situation after the air pressure in the coolant pipeline reaches the test air pressure;

[0039] In summary, the pipeline air tightness detection device 100 can perform air tightness detection on the pipeline of the cooling system, thereby reducing the probability of coolant leakage in the cooling system of the fan due to the air tightness of the pipeline not meeting the requirements, thereby avoiding the need to clean the fan or shut down the fan due to coolant leakage. Therefore, it can ensure that the cooling system of the fan can operate normally and stably, thereby providing guarantee for the normal operation of the fan.

[0040] For further information, please refer to Figure 1 and Figure 2In this embodiment, a large number of pipelines are needed when assembling the cooling system of the fan, and multiple fans may be assembled at the same time at the assembly site. Based on this, when performing air tightness detection of the pipeline, the detection efficiency needs to be improved. Based on this, this embodiment adopts a first connecting component 120 connected to the pressurized air pump 110, and the first connecting component 120 is configured with multiple first pipe joints 121, and the multiple first pipe joints 121 are all connected to the pressurized air pump 110; the second connecting component 130 is configured with multiple second pipe joints 131; wherein the multiple first pipe joints 121 correspond one to one with the multiple second pipe joints 131.

[0041] Thus, in this way, multiple groups can be formed by one-to-one correspondence between multiple first pipe joints 121 and multiple second pipe joints 131, so that the detection work of multiple coolant pipelines 10 to be tested can be performed simultaneously, thereby improving the detection efficiency.

[0042] When the multiple first pipe joints 121 and the multiple second pipe joints 131 are used to test the multiple coolant pipelines 10 to be tested, in order to facilitate the injection of pressurized gas into the multiple coolant pipelines 10 to be tested, the pipeline airtightness detection device 100 also includes a main pipeline 151 and multiple branch pipelines 152; the main pipeline 151 is connected to the pressurized air pump 110, one end of the multiple branch pipelines 152 is connected to the main pipeline 151, and the other end of the multiple branch pipelines 152 is connected to the multiple first pipe joints 121 in a one-to-one correspondence; thus, the step of injecting pressurized gas can be completed by a pressurized air pump 110, thereby improving the efficiency of the test. Under this condition, since the progress of the test work of the multiple coolant pipelines 10 to be tested may be inconsistent, in order to independently control the step of injecting pressurized gas into the multiple coolant pipelines 10 to be tested, a first on-off valve 153 is provided on each branch pipeline 152.

[0043] Based on the above content, in order to accurately perform air tightness detection, the air pressure detection component 140 is required to detect the pressure change of the coolant pipeline 10 to be tested during the stage of injecting pressurized air and after the air pressure reaches the test air pressure. Therefore, the air pressure detection component 140 includes multiple first air pressure detectors 141 and multiple second air pressure detectors 142; the multiple first air pressure detectors 141 are connected to multiple branch pipes 152 or multiple first pipe joints 121 in a one-to-one manner; and the multiple second air pressure detectors 142 are connected to multiple second pipe joints 131 in a one-to-one manner.

[0044] By setting up multiple first air pressure detectors 141, the pressure change of the coolant pipeline 10 to be tested during the stage of injecting pressurized air can be detected, and by using multiple second air pressure detectors 142, the pressure change of the coolant pipeline 10 to be tested after the air pressure reaches the test air pressure can be detected, so that the air tightness of each coolant pipeline 10 to be tested can be accurately judged.

[0045] It should be noted that, in this embodiment, when multiple first air pressure detectors 141 are configured, a method is adopted in which multiple first air pressure detectors 141 are connected to multiple branch pipes 152 in a one-to-one correspondence, and the connection between the first air pressure detector 141 and the branch pipe 152 is located on the side of the first on-off valve 153 close to the second pipe joint 131. In addition, when the first air pressure detector 141 and the second air pressure detector 142 are configured, the first air pressure detector 141 and the second air pressure detector 142 are both electronic barometers or pressure gauges.

[0046] For further information, please refer to Figure 1 and Figure 2 In this embodiment, since the pressure in the coolant pipeline 10 to be tested is relatively high after the air tightness test is completed, in order to ensure the safety of the site, the pipeline air tightness test device 100 further includes a pressure relief component 160; the pressure relief component 160 is connected to the first connection component 120 or the second connection component 130. The pressure relief component 160 can be used to relieve the pressure of the coolant pipeline 10 to be tested that has completed the air tightness test, so that the coolant pipeline 10 to be tested can be removed from the first pipe joint 121 and the second pipe joint 131 after the pressure relief is completed, thereby improving the safety of the test.

[0047] Specifically, when configuring the pressure relief assembly 160, the present embodiment adopts that the pressure relief assembly 160 includes a main pressure relief valve 161 and a plurality of air guide pipes 162, the plurality of air guide pipes 162 are all connected to the main pressure relief valve 161, and the plurality of air guide pipes 162 are connected to the plurality of first pipe joints 121 in a one-to-one correspondence; wherein the plurality of air guide pipes 162 are all provided with a second on-off valve 163. That is, in this way, the pressure relief can be performed through the main pressure relief valve 161, and the pressure relief state of each coolant pipeline 10 to be tested can be controlled by the corresponding second on-off valve 163. In other embodiments of the present utility model, the pressure relief assembly 160 can also include a plurality of pressure relief valves, and the plurality of pressure relief valves are connected to the plurality of second pipe joints 131 in a one-to-one correspondence, that is, each second pipe joint 131 can also be connected to a corresponding pressure relief valve, so that the pressure relief state of each coolant pipeline 10 to be tested can be independently controlled by the corresponding pressure relief valve.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
