Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of manifold, in particular to a manifold drying device and a manifold drying method. BACKGROUND

[0002] The manifold is a device for uniformly distributing and conveying cooling liquid, which is provided with a main path and a plurality of branch paths, and the flow of the main path can be uniformly distributed to each branch path through structural design. The manifold is often used in the liquid cooling heat dissipation structure of a server cabinet to ensure that the required cooling liquid flow of each server inside the server cabinet is consistent. During the machining and manufacturing process of the manifold, there are residual cooling liquid on the inside and outer wall of the manifold during pressure testing and cleaning of the manifold. Therefore, after manufacturing is completed, the manifold needs to be dried to avoid rust and contamination caused by residual cooling liquid on the manifold.

[0047] The first valve is used to connect the exhaust with the inner cavity, and the second valve is used to connect the main path of the distribution header with the inner cavity.

At this time, the hot air in the air inlet system is introduced into the inner cavity through the first valve, the gas in the inner cavity flows and flows to the collection and exhaust system through the second valve, so that the gaseous cooling liquid in the inner cavity is exhausted, and the outer wall of the distribution header is dried.

DETAILED DESCRIPTION

[0062] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0063] The embodiments of the present application are described below in combination with Figures 1 to 10 .

[0064] According to the embodiments of the present application, in one aspect, a water collector drying device is provided, as shown in Figure 1 , comprising a box 1, an exhaust 24, an air inlet system 7, a first valve 2, a first heating device 3, a collection and discharge system 8 and a second valve 4.

[0065] The box 1 is provided with an inner cavity for placing the water collector 25. The exhaust 24 is arranged in the inner cavity, and the exhaust 24 is provided with a plurality of exhaust ports 83, each of which is used to communicate with each branch of the water collector 25 one by one.

[0066] The air inlet system 7 is used to generate hot air. The air inlet system 7, the exhaust 24 and the inner cavity are all in communication with the first valve 2, so that any two of the air inlet system 7, the exhaust 24 and the inner cavity can be selectively communicated through the first valve 2.

[0067] The first heating device 3 is arranged in the inner cavity and is used to heat the inner cavity. That is, after the water collector 25 is placed in the inner cavity, the first heating device 3 can heat the inner cavity to heat and dry the water collector 25.

[0068] The collection and discharge system 8 is used to collect and discharge fluid. The collection and discharge system 8, the inner cavity and the main path of the water collector 25 are all in communication with the second valve 4, so that any two of the collection and discharge system 8, the inner cavity and the main path of the water collector 25 can be selectively communicated through the second valve 4.

[0069] When the water collector 25 needs to be dried, the water collector 25 is placed in the inner cavity of the box 1, and the main path of the water collector 25 is communicated with the second valve 4, and the branch of the water collector 25 is communicated with the exhaust port on the exhaust 24 one by one.

[0070] First, the inside of the water collector 25 is dried, as shown in Figure 3As shown, the first valve 2 is used to connect the air inlet system 7 with the air exhaust 24, and the second valve 4 is used to connect the main path of the distribution header 25 with the collection and discharge system 8. At this time, the hot air in the air inlet system 7 is introduced into the air exhaust 24 through the first valve 2, and then the hot air is introduced into each branch path of the distribution header 25 through the air exhaust ports, and then the hot air is introduced into the main path of the distribution header 25 and is discharged through the second valve 4 to the collection and discharge system 8. When the hot air flows through the branch paths and the main path of the distribution header 25, the cooling liquid remaining in the branch paths and the main path of the distribution header 25 is removed, and the inside of the branch paths and the main path of the distribution header 25 is dried.

[0071] Then, the outside wall of the distribution header 25 is dried, as shown in Figure 5 The first valve 2 is used to connect the air exhaust 24 with the inner cavity, and the second valve 4 is used to connect the main path of the distribution header 25 with the inner cavity. The first heating device 3 is used to heat the inner cavity, so that the temperature in the inner cavity is increased, and the cooling liquid on the outside wall of the distribution header 25 and the cooling liquid remaining in the inside of the distribution header 25 is vaporized. Then, the first valve 2 is used to connect the air inlet system 7 with the inner cavity, and the second valve 4 is used to connect the inner cavity of the box body 1 with the collection and discharge system 8. At this time, the hot air in the air inlet system 7 is introduced into the inner cavity through the first valve 2, and the gas in the inner cavity is discharged through the second valve 4 to the collection and discharge system 8, so that the gaseous cooling liquid in the inner cavity is removed.

[0072] Then, the gaseous cooling liquid in the distribution header 25 is removed, as shown in Figure 6 The first valve 2 is used to connect the air inlet system 7 with the air exhaust 24, and the second valve 4 is used to connect the main path of the distribution header 25 with the collection and discharge system 8. At this time, the hot air in the air inlet system 7 is introduced into the air exhaust 24 through the first valve 2, and then the hot air is introduced into each branch path of the distribution header 25 through the air exhaust ports, and then the hot air is introduced into the main path of the distribution header 25 and is discharged through the second valve 4 to the collection and discharge system 8, so that the gaseous cooling liquid in the distribution header 25 is removed.

[0073] In this way, not only the outside wall of the distribution header 25 is effectively dried, but also the inside of the distribution header 25 is effectively dried, so that the corrosion and the pollution caused by the remaining cooling liquid in the inside of the distribution header 25 are avoided.

[0074] The air exhaust 24 is provided with a main passage and a plurality of branch passages, each branch passage is in communication with the main passage, each air exhaust port 83 is in one-to-one correspondence with each branch passage, and the main passage is in communication with the first valve 2.

[0075] The first valve 2 and the second valve 4 are three-way valves.

[0076] In an embodiment, as shown in Figure 2As shown, the bottom of the box body 1 is provided with a drain 13 communicating with the inner cavity, and the drain 13 is provided with a drain valve. After the distribution header 25 is placed in the inner cavity of the box body 1, part of the cooling liquid flows out and falls to the bottom of the box body 1, and the cooling liquid can be discharged from the inner cavity and collected by opening the drain valve.

[0077] In some embodiments, as shown in Figure 2 As shown, the bottom of the inner cavity of the box body 1 is provided with an inclined surface 14, and the drain 13 is located at the bottom of the inclined surface 14, which facilitates the discharge of liquid.

[0078] In one embodiment, the first heating device 3 is provided as a heat exchanger, and a heat exchange medium is used to flow through the heat exchanger. When a heat exchange medium with a temperature higher than that of the inner cavity flows through the heat exchanger, the heat exchanger can heat the inner cavity.

[0079] Specifically, the heat exchanger is provided with a medium passage, and the heat exchange medium can be hot water. When the hot water flows through the medium passage, it exchanges heat with the air in the inner cavity, thereby heating the inner cavity.

[0080] In this way, compared with using hot air to directly blow the distribution header 25, the direct impact on the distribution header 25 is smaller, and the aging of non-metallic elements such as rubber of the distribution header 25 is avoided.

[0081] In one embodiment, as shown in Figure 1 As shown, the distribution header drying device further comprises a negative pressure generating assembly 9, which communicates with the inner cavity and is used to generate negative pressure in the inner cavity.

[0082] When drying the outer wall of the distribution header 25, the negative pressure generating assembly 9 is used to first draw air out of the inner cavity to reduce the pressure in the inner cavity. Thus, the boiling point of the cooling liquid is reduced, i.e., the vaporization temperature condition of the cooling liquid is lower. Thereafter, when the first heating device 3 is used to heat the inner cavity, it only needs to be heated to a relatively low temperature, so that the cooling liquid can be vaporized, thereby reducing the temperature cost and reducing the impact of temperature on the distribution header 25 itself.

[0083] In one embodiment, as shown in Figure 9 As shown, the negative pressure generating assembly 9 comprises a sixth valve 91 and a vacuum pump 92, and the vacuum pump 92 communicates with the inner cavity through the sixth valve 91. Thus, the vacuum pump 92 can be used to draw air out of the inner cavity to reduce the air pressure in the inner cavity. After the air is drawn out, the sixth valve 91 is closed to maintain the air pressure in the inner cavity.

[0084] In some embodiments, the negative pressure generating assembly 9 further comprises a gas-liquid separation device 93, and the vacuum pump 92 communicates with the gas-liquid separation device 93. The gas discharged by the vacuum pump 92 can enter the gas-liquid separation device 93, and the gas-liquid separation device 93 can separate the liquid mixed in the gas. Thereafter, the gas is discharged, and the liquid is discharged and collected.

[0085] A first one-way valve 94 can be arranged on the pipeline between the vacuum pump 92 and the gas-liquid separation device 93, so that the gas can flow from the vacuum pump 92 to the gas-liquid separation device 93, and cannot flow from the gas-liquid separation device 93 to the vacuum pump 92, thereby avoiding backflow of the gas.

[0086] A first sound-damping filter element 95 can be arranged on the pipeline between the vacuum pump 92 and the gas-liquid separation device 93, so as to reduce noise and filter impurities.

[0087] In some embodiments, the box 1 is provided with a second temperature detection element 15 and a second pressure detection element 16. The second temperature detection element 15 is used to detect the temperature of the inner cavity, and the second pressure detection element 16 is used to detect the pressure of the inner cavity.

[0088] In some embodiments, a third temperature detection element 17, a third pressure detection element 18, and a second one-way valve 19 are arranged on the pipeline between the second valve 4 and the collection and discharge system 8. The third temperature detection element 17 is used to detect the temperature of the fluid, and the second pressure detection element 16 is used to detect the pressure of the fluid. The second one-way valve 19 allows the fluid to flow from the second valve 4 to the collection and discharge system 8, and cannot flow from the collection and discharge system 8 to the second valve 4, thereby avoiding backflow.

[0089] In one embodiment, as shown in Figure 2 The distribution water collector drying apparatus further comprises a weighing element 5. The weighing element 5 is arranged in the inner cavity, and the weighing element 5 is used to be connected with the distribution water collector 25 and can detect the weight of the distribution water collector 25.

[0090] When drying the inside of the distribution water collector 25, the weight of the distribution water collector 25 is detected in real time. As the hot air flows through the branch and main path of the distribution water collector 25, the residual coolant in the branch and main path of the distribution water collector 25 is carried out, and the inside of the branch and main path of the distribution water collector 25 is blown dry. When it is detected that the weight of the distribution water collector 25 does not change significantly, it can be judged that the inside of the distribution water collector 25 is dried.

[0091] When drying the outer wall of the distributor 25, the weight of the distributor 25 is detected in real time. As the first heating device 3 heats the inner cavity, the cooling liquid on the outer wall of the distributor 25 and the cooling liquid still remaining in the distributor 25 are vaporized. When it is detected that the weight of the distributor 25 does not change significantly, it is determined that the cooling liquid is completely vaporized. Then the first valve 2 is used to connect the air inlet system 7 to the inner cavity of the box 1, and the second valve 4 is used to connect the inner cavity of the box 1 to the collection and discharge system 8. At this time, the air inlet system 7 passes hot air into the inner cavity through the first valve 2, the gas in the inner cavity flows and flows to the collection and discharge system 8 through the second valve 4, so as to discharge the gaseous cooling liquid in the inner cavity. Then the first valve 2 is used to connect the air inlet system 7 to the exhaust 24, and the second valve 4 is used to connect the main path of the distributor 25 to the collection and discharge system 8. At this time, the air inlet system 7 passes hot air into the exhaust 24 through the first valve 2, and the hot air is correspondingly introduced into each branch of the distributor 25 through each exhaust port, and then the hot air is uniformly introduced into the main path of the distributor 25 and then flows to the collection and discharge system 8 through the second valve 4 to be collected and discharged, so as to discharge the gaseous cooling liquid in the distributor 25.

[0092] In this way, the drying condition of the distributor 25 is determined by detecting the weight of the distributor 25, which is more timely and accurate, avoids low efficiency caused by too long drying time, and also avoids incomplete drying caused by too short drying time.

[0093] In some embodiments, the weighing member 5 can be a weighing sensor, one end of the weighing sensor is connected to the inner wall of the inner cavity, and the other end of the weighing sensor is used to hoist the distributor 25.

[0094] In one embodiment, as shown in Figure 2 The distributor drying device also includes a first humidity detection element 11 and a second humidity detection element 12. The first humidity detection element 11 is arranged on the box 1 and is used to detect the humidity in the inner cavity.

[0095] When drying the outer wall of the distributor 25, the first heating device 3 is used to heat the inner cavity, so that the temperature in the inner cavity rises, so that the cooling liquid on the outer wall of the distributor 25 and the cooling liquid on the inner wall of the distributor 25 are vaporized. Then the first valve 2 is used to connect the air inlet system 7 to the inner cavity of the box 1, and the second valve 4 is used to connect the inner cavity of the box 1 to the collection and discharge system 8. At this time, the air inlet system 7 passes hot air into the inner cavity through the first valve 2, the gas in the inner cavity flows and flows to the collection and discharge system 8 through the second valve 4, so as to discharge the gaseous cooling liquid in the inner cavity. At this time, the first humidity detection element 11 is used to detect the humidity in the inner cavity in real time, and when it is detected that the humidity in the inner cavity reaches a specified value and does not change significantly, it is determined that the gaseous cooling liquid in the inner cavity is completely discharged.

[0096] The second humidity detection element 12 is arranged between the collecting exhaust system 8 and the second valve 4, and is used to detect the humidity of the fluid flowing to the collecting exhaust system 8.

[0097] When the gaseous cooling liquid in the water collector 25 is to be discharged, the first valve 2 is used to communicate the air inlet system 7 with the exhaust 24, and the second valve 4 is used to communicate the main path of the water collector 25 with the collecting exhaust system 8. At this time, the hot air in the air inlet system 7 is introduced into the exhaust 24 through the first valve 2, and then the hot air is introduced into each branch path of the water collector 25 through each exhaust port, and then the hot air is introduced into the main path of the water collector 25 and then flows to the collecting exhaust system 8 through the second valve 4, so as to be collected and discharged, thereby discharging the gaseous cooling liquid in the water collector 25. At this time, the second humidity detection element 12 is used to detect the humidity of the fluid flowing to the collecting exhaust system 8 in real time, and when the humidity of the fluid flowing to the collecting exhaust system 8 reaches a specified value and does not change significantly, it is judged that the gaseous cooling liquid in the water collector 25 is discharged.

[0098] In this way, the humidity of the inner cavity is detected by the first humidity sensor, and the humidity of the fluid flowing to the collecting exhaust system 8 is detected by the second humidity sensor, so that the discharge of the gaseous cooling liquid is judged, which is more timely and accurate, avoids low efficiency caused by too long discharge time, and also avoids incomplete discharge of the gaseous cooling liquid caused by too short discharge time.

[0099] The first humidity detection element 11 and the second humidity detection element 12 can be a temperature and humidity sensor.

[0100] In some embodiments, the weighing element 5, the first humidity detection element 11 and the second humidity detection element 12 can be used in cooperation to more accurately control the drying condition of the water collector 25.

[0101] In one embodiment, as shown in Figure 2 The seventh valve 20 is in communication with the second valve 4, and the seventh valve 20 is in communication with the collecting exhaust system 8 through the first pipeline 21 and the second pipeline 22 respectively, so that the second valve 4 can be selectively communicated with the first pipeline 21 or the second pipeline 22 through the seventh valve 20. The second humidity detection element 12 is arranged on the first pipeline 21.

[0102] As shown in Figure 5As shown, when the first valve 2 connects the air intake system 7 to the inner cavity of the housing 1, and the second valve 4 connects the inner cavity of the housing 1 to the collection and discharge system 8, the seventh valve 20 connects the second valve 4 to the second pipeline 22. The gas inside the inner cavity can flow sequentially through the second valve 4, the seventh valve 20, and the second pipeline 22 to the collection and discharge system 8. At this time, the gas flow does not pass through the second humidity detection element 12. This reduces the frequency of use of the second humidity detection element 12 and increases its service life.

[0103] like Figure 6 As shown, when the first valve 2 connects the air intake system 7 to the exhaust component 24, and the second valve 4 connects the main line of the manifold 25 to the collection and discharge system 8, the seventh valve 20 connects the second valve 4 to the first pipeline 21. At this time, the gas in the manifold 25 flows sequentially through the second valve 4, the seventh valve 20, and the first pipeline 21 to the collection and discharge system 8. The second temperature detection element 15 installed on the first pipeline 21 can normally detect the humidity of the gas in the manifold 25.

[0104] In some embodiments, such as Figure 6 As shown, a third check valve 23 is provided on the first pipeline 21, which allows fluid to flow from the second humidity detection element 12 to the collection and discharge system 8, but not from the collection and discharge system 8 to the second humidity detection element 12, thus avoiding backflow.

[0105] In one embodiment, such as Figure 2 As shown, the water manifold drying equipment also includes a third valve 6 and a fourth valve 10.

[0106] The air intake system 7, the first valve 2, and the second valve 4 are all connected to the third valve 6, so that the air intake system 7 can be selectively connected to one of the first valve 2 and the second valve 4 through the third valve 6.

[0107] The collection and discharge system 8, the first valve 2, and the second valve 4 are all connected to the fourth valve 10, so that the collection and discharge system 8 can be selectively connected to one of the first valve 2 and the second valve 4 through the fourth valve 10.

[0108] When drying the inside of the water distributor 25, such as Figure 3 As shown, the air intake system 7 is connected to the first valve 2 using the third valve 6, and the third valve 6 is connected to the exhaust component 24 using the first valve 2, thereby connecting the air intake system 7 and the exhaust component 24. Simultaneously, the fourth valve 10 is connected to the collection and discharge system 8 and the second valve 4, and the second valve 4 is used to connect the fourth valve 10 to the main line of the manifold 25, thereby connecting the collection and discharge system 8 to the main line of the manifold 25.

[0109] The air inlet system 7 is connected to the main path of the water collector 25 through the third valve 6 and the second valve 4, and the hot air is introduced into the water collector 25 through the branch paths of the water collector 25 corresponding to each air outlet of the air exhaust 24, and then the hot air is introduced into the air exhaust 24. The air exhaust 24 is connected to the collection and discharge system 8 through the first valve 2 and the fourth valve 10, and the hot air is collected and discharged by the collection and discharge system 8. When the hot air flows through the main path and the branch paths of the water collector 25, the residual cooling liquid in the main path and the branch paths of the water collector 25 is carried out, and the inside of the main path and the branch paths of the water collector 25 is dried, realizing forward drying.

[0110] As shown in Figure 4 , the third valve 6 is used to connect the air inlet system 7 to the second valve 4, and the second valve 4 is used to connect the third valve 6 to the main path of the water collector 25, so that the air inlet system 7 is connected to the main path of the water collector 25. At the same time, the fourth valve 10 is used to connect the collection and discharge system 8 to the first valve 2, so that the first valve 2 connects the fourth valve 10 to the air exhaust 24, and the collection and discharge system 8 is connected to the air exhaust 24.

[0111] The air inlet system 7 is connected to the main path of the water collector 25 through the third valve 6 and the second valve 4, and the hot air is introduced into the water collector 25 through the branch paths of the water collector 25 corresponding to each air outlet of the air exhaust 24, and then the hot air is introduced into the air exhaust 24. The air exhaust 24 is connected to the collection and discharge system 8 through the first valve 2 and the fourth valve 10, and the hot air is collected and discharged by the collection and discharge system 8. When the hot air flows through the main path and the branch paths of the water collector 25, the residual cooling liquid in the main path and the branch paths of the water collector 25 is carried out, and the inside of the main path and the branch paths of the water collector 25 is dried, realizing forward drying.

[0112] In this way, the inside of the water collector 25 is dried twice in forward and reverse directions, and the drying effect of the inside of the water collector 25 is better.

[0113] The third valve 6 and the fourth valve 10 can be three-way valves.

[0114] In an embodiment, as shown in Figure 8 , the collection and discharge system 8 includes a collection tank 81, a fifth valve 82, an exhaust port 83, a first liquid level detection element 84, a second liquid level detection element 85, and a control module. The collection tank 81 is connected to the second valve 4, and the fifth valve 82 is connected to the collection tank 81 and is used to discharge liquid. The exhaust port 83 is arranged on the collection tank 81 and is connected to the inside of the collection tank 81, and the exhaust port 83 is used to discharge gas.

[0115] The first liquid level detecting element 84 and the second liquid level detecting element 85 are arranged in the collecting tank 81. The first liquid level detecting element 84 is used to detect the liquid in the collecting tank 81 is at a first liquid level, and the second liquid level detecting element 85 is used to detect the liquid in the collecting tank 81 is at a second liquid level. The first liquid level is higher than the second liquid level.

[0116] The control module is in communication connection with the first liquid level detecting element 84, the second liquid level detecting element 85 and the fifth valve 82 respectively. Thus, the control module can control the fifth valve 82 to open when the liquid in the collecting tank 81 is at the first liquid level. The control module can also control the fifth valve 82 to close when the liquid in the collecting tank 81 is at the second liquid level.

[0117] In this way, the gas and the liquid flow out of the second valve 4 and then flow to the collecting tank 81 for collection. The gas is discharged from the exhaust port 83. The liquid accumulates in the collecting tank 81. When the first liquid level detecting element 84 detects that the liquid in the collecting tank 81 is at the first liquid level, the control module controls the fifth valve 82 to open to discharge the liquid. When the first liquid level detecting element 84 detects that the liquid in the collecting tank 81 is at the first liquid level, the control module controls the fifth valve 82 to open to discharge the liquid. With the discharge of the liquid, the liquid level drops. When the second liquid level detecting element 85 detects that the liquid in the collecting tank 81 is at the second liquid level, the control module controls the fifth valve 82 to close to stop discharging the liquid.

[0118] In some embodiments, the collecting and discharging system 8 further comprises a third liquid level detecting element 89 and an alarm module. The third liquid level detecting element 89 is used to detect the liquid in the collecting tank 81 is at a third liquid level. The third liquid level is higher than the first liquid level. The third liquid level detecting element 89 and the alarm module are in communication connection with the control module respectively. The control module can control the alarm module to alarm when the liquid in the collecting tank 81 is at the third liquid level.

[0119] When the fifth valve 82 is damaged, or the liquid accumulates too fast, the liquid level continues to rise. When the third liquid level detecting element 89 detects that the liquid in the collecting tank 81 is at the third liquid level. The control module controls the alarm module to alarm to alert the operator to handle in time.

[0120] The control module can be a PLC, i.e. a programmable logic controller.

[0121] In one embodiment, the collecting and discharging system 8 further comprises a first manual valve 86, a first automatic valve 87 and a liquid discharging pump 88. The first manual valve 86 is in communication with the fifth valve 82. After the fifth valve 82 is opened, opening the first manual valve 86 can discharge the liquid.

[0122] The first automatic valve 87 is connected to the fifth valve 82, and the drain pump 88 is connected to the first automatic valve 87. The control module is connected to both the drain pump 88 and the first automatic valve 87. The control module is used to control the first automatic valve 87 and the drain pump 88 to open when the liquid in the collection tank 81 is at the first liquid level. The control module is also used to control the first automatic valve 87 and the drain pump 88 to close when the liquid in the collection tank 81 is at the second liquid level.

[0123] When the first liquid level detection element 84 detects that the liquid in the collection tank 81 is at the first liquid level, it controls the fifth valve 82 and the first automatic valve 87 to open, and controls the drain pump 88 to start. Under the suction action of the drain pump 88, the liquid in the collection tank 81 is discharged sequentially through the fifth valve 82 and the first automatic valve 87. As the liquid is discharged, the liquid level drops. When the second liquid level detection element 85 detects that the liquid in the collection tank 81 is at the second liquid level, the control module controls the fifth valve 82 and the first automatic valve 87 to close, and controls the drain pump 88 to shut down, so as to stop the discharge of liquid.

[0124] This setting allows for selective manual or automatic drainage.

[0125] In some embodiments, the collection and discharge system 8 also includes a flow switch 810, which is disposed between the fifth valve 82 and the first automatic valve 87. When the flow rate between the fifth valve 82 and the first automatic valve 87 is lower than a preset value, the flow switch 810 automatically closes.

[0126] In one embodiment, such as Figure 7 As shown, the air intake system 7 includes an air intake interface 71, a second heating device 72, a pressure regulating element 73, a first temperature detection element 74, and a temperature and humidity detection element 75. The air intake interface 71 is used to connect to an external air source. The air intake interface 71 is connected to the first valve 2 through the second heating device 72, which is used to heat the gas flowing from the air intake interface 71 to the first valve 2.

[0127] The pressure regulating element 73 is connected to the pipeline between the air inlet 71 and the second heating device 72, and is used to regulate the gas pressure entering the second heating device 72. The first temperature sensing element 74 is connected to the pipeline between the second heating device 72 and the first valve 2, and is used to detect the temperature of the gas heated by the second heating device 72, so as to control the temperature of the gas entering through the first valve 2.

[0128] The temperature and humidity detection element 75 is installed on the pipeline between the air inlet 71 and the second heating device 72, and is used to detect the temperature and humidity of the gas entering the air inlet 71.

[0129] The gas from the external gas source enters the air inlet interface 71, is heated by the second heating device 72, and then flows to the first valve 2 to realize the input of hot air. The pressure adjusting element 73 can adjust the pressure of the gas to make the pressure of the gas flowing into the first valve 2 meet the requirements. The temperature detecting element can detect the pressure of the gas to make the temperature of the gas flowing into the first valve 2 meet the requirements. The temperature and humidity detecting element 75 can detect the temperature and humidity of the gas from the external gas source to avoid that the temperature and humidity of the gas from the external gas source are too high.

[0130] In some embodiments, the air inlet system 7 further comprises an eighth valve 76 and a discharge pipeline 77, the discharge pipeline 77 communicates with the air inlet interface 71 through the eighth valve 76, and the temperature and humidity detecting element 75 is arranged on the discharge pipeline 77, so that the temperature and humidity of the gas entering the air inlet interface 71 can be detected by opening the eighth valve 76. The eighth valve 76 can be closed in normal state to reduce the frequency of use of the temperature and humidity detecting element 75.

[0131] In some embodiments, the air inlet system 7 further comprises a second sound-attenuating filtering element 78, which is arranged on the discharge pipeline 77 to reduce the noise of the gas flow.

[0132] In some embodiments, the air inlet system 7 further comprises a fourth one-way valve 79, which is arranged on the discharge pipeline 77 to enable the gas flow to be discharged outwardly and unable to flow back through the discharge pipeline 77.

[0133] In some embodiments, the air inlet system 7 further comprises a second manual valve 710, which is arranged between the air inlet interface 71 and the second heating device 72. When the first manual valve 86 is opened, the gas from the external gas source can flow to the second heating device 72. When the first manual valve 86 is closed, the gas from the external gas source cannot flow to the second heating device 72.

[0134] In some embodiments, the air inlet system 7 further comprises a fourth pressure detecting element 711, which is arranged between the air inlet interface 71 and the first manual valve 86, and can detect the pressure of the gas from the external gas source.

[0135] In some embodiments, the air inlet system 7 further comprises a filtering device 712, which is arranged between the air inlet interface 71 and the second heating device 72 to filter the gas flowing from the air inlet interface 71 to the second heating device 72.

[0136] In some embodiments, the air inlet system 7 further comprises a fifth pressure detecting element 713 and a flow detecting element 714, both of which are arranged between the air inlet interface 71 and the second heating device 72 to detect the pressure and flow of the gas flowing from the air inlet interface 71 to the second heating device 72.

[0137] In some embodiments, the air inlet system 7 further comprises a fifth one-way valve 715 arranged between the second heating device 72 and the first valve 2 to allow the gas to flow from the second heating device 72 to the first valve 2 but not vice versa, thereby preventing backflow.

[0138] In some embodiments, the air inlet system 7 further comprises a second automatic valve 716 arranged between the air inlet interface 71 and the second heating device 72. When the second automatic valve 716 is opened, the gas from the external gas source can flow to the second heating device 72. When the second automatic valve 716 is closed, the gas from the external gas source cannot flow to the second heating device 72.

[0139] According to the embodiments of the present application, in another aspect, a water collector drying method is also provided, as shown in the following. Figure 10

[0140] Place the water collector 25 into the inner cavity of the box 1, and connect the main path of the water collector 25 with the second valve 4 and connect the branch path of the water collector 25 with the exhaust ports on the exhaust member 24 one by one;

[0141] Control the first valve 2 to connect the air inlet system 7 with the exhaust member 24, control the second valve 4 to connect the main path of the water collector 25 with the collection and discharge system 8, and control the air inlet system 7 to introduce hot air into the exhaust member 24;

[0142] Control the first valve 2 to connect the exhaust member 24 with the inner cavity, control the second valve 4 to connect the main path of the water collector 25 with the inner cavity, and control the first heating device 3 to heat the inner cavity;

[0143] Control the first valve 2 to connect the air inlet system 7 with the inner cavity of the box 1, control the second valve 4 to connect the inner cavity of the box 1 with the collection and discharge system 8, and control the air inlet system 7 to introduce hot air into the inner cavity of the box 1;

[0144] Control the first valve 2 to connect the air inlet system 7 with the exhaust member 24, control the second valve 4 to connect the main path of the water collector 25 with the collection and discharge system 8, and control the air inlet system 7 to introduce hot air into the exhaust member 24.

[0145] ​Specifically, when the distributor 25 needs to be dried, the distributor 25 is placed in the inner cavity of the box 1, the main path of the distributor 25 is communicated with the second valve 4, and the branch paths of the distributor 25 are communicated with the exhaust ports on the exhaust member 24 one by one.

[0146] First, the interior of the distributor 25 is dried, the first valve 2 is controlled to communicate the air inlet system 7 with the exhaust member 24, and the second valve 4 is controlled to communicate the main path of the distributor 25 with the collection and discharge system 8. At this time, the air inlet system 7 passes hot air into the exhaust member 24 through the first valve 2, the hot air is correspondingly passed into each branch path of the distributor 25 through each exhaust port, and then the hot air is uniformly passed into the main path of the distributor 25 and flows to the collection and discharge system 8 through the second valve 4 to be collected and discharged. When the hot air flows through the branch paths and the main path of the distributor 25, the cooling liquid remaining in the branch paths and the main path of the distributor 25 is carried out, and the interior of the branch paths and the main path of the distributor 25 is blown dry.

[0147] Then, the outer wall of the distributor 25 is dried, the first valve 2 is controlled to communicate the exhaust member 24 with the inner cavity, and the second valve 4 is controlled to communicate the main path of the distributor 25 with the inner cavity. The first heating device 3 is controlled to heat the inner cavity, so that the temperature in the inner cavity is increased, and the cooling liquid on the outer wall of the distributor 25 and the cooling liquid still remaining in the interior of the distributor 25 are vaporized. Then, the first valve 2 is controlled to communicate the air inlet system 7 with the inner cavity of the box 1, and the second valve 4 is controlled to communicate the inner cavity of the box 1 with the collection and discharge system 8. At this time, the air inlet system 7 passes hot air into the inner cavity through the first valve 2, the gas in the inner cavity flows and flows to the collection and discharge system 8 through the second valve 4, so that the gaseous cooling liquid in the inner cavity is discharged.

[0148] Then, the gaseous cooling liquid in the distributor 25 is discharged, the first valve 2 is controlled to communicate the air inlet system 7 with the exhaust member 24 again, and the second valve 4 is controlled to communicate the main path of the distributor 25 with the collection and discharge system 8 again. At this time, the air inlet system 7 passes hot air into the exhaust member 24 through the first valve 2, the hot air is correspondingly passed into each branch path of the distributor 25 through each exhaust port, and then the hot air is uniformly passed into the main path of the distributor 25 and flows to the collection and discharge system 8 through the second valve 4 to be collected and discharged, so that the gaseous cooling liquid in the distributor 25 is discharged.

[0149] In this way, not only the outer wall of the distributor 25 is effectively dried, but also the interior of the distributor 25 is effectively dried, so that rusting and deterioration and pollution of the cooling liquid caused by the remaining cooling liquid in the interior of the distributor 25 are avoided.

[0150] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
