In order to make the present invention better understood by those skilled in the art, the following description of the present invention will be made in detail with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the invention. All other embodiments, based on the embodiments of the invention, which a person skilled in the art would obtain without making any inventive effort, are within the scope of the invention.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a heat exchange unit 10, where the heat exchange unit 10 may be a liquid cooling unit, an air conditioning unit, or others. The heat exchanger unit 10 includes a degasser 11 and a housing 12, the degasser 11 is provided in the housing 12, and the degasser 11 can discharge the gas of the circulating liquid. Housing 12 may provide some protection to degasser 11, thus helping to avoid damage to degasser 11. The heat exchanger unit 10 will be described below as an example of a liquid cooling unit.
Referring to fig. 2, in the present embodiment, the degasser 11 includes a water tank 111, a water inlet valve assembly 112, a water outlet pump assembly 113, and an exhaust valve 114, wherein the water inlet valve assembly 112, the water outlet pump assembly 113, and the exhaust valve 114 are connected to the water tank 111. The water tank 111 may be a closed tank, and when the water tank 111 is filled with liquid, the liquid in the water tank 111 is isolated from the outside. The water tank 111 is provided with a liquid inlet end 1111, a liquid outlet end 1112 and a gas exhaust end 1113, the degasser 11 can realize liquid inlet through the liquid inlet end 1111, the degasser 11 can realize liquid outlet through the liquid outlet end 1112, and the degasser 11 can realize gas exhaust through the gas exhaust end 1113.
Referring to fig. 2 and 3 together, in the present embodiment, the water tank 111 includes a water tank body 1114 and a liquid-equalizing member 1115, and the liquid-equalizing member 1115 is assembled in the water tank body 1114. The liquid-homogenizing member 1115 may be a thin plate or a coil, and the liquid-homogenizing member 1115 may be detachably assembled in the water tank body 1114 by means of clamping, fastening, etc., so as to facilitate the disassembly and cleaning of the liquid-homogenizing member 1115. The liquid-equalizing member 1115 is provided with a plurality of outlet holes 1116, and the outlet holes 1116 are located between the bottom and top of the tank body 1114.
Specifically, when the degasser 11 works, the liquid entering from the liquid inlet valve assembly 112 flows into the liquid homogenizing member 1115, and the liquid contacts with the liquid homogenizing member 1115, at this time, the liquid may be spread on the liquid homogenizing member 1115, and the liquid on the liquid homogenizing member 1115 finally flows into the water tank body 1114 through the water outlet holes 1116 because the liquid homogenizing member 1115 is provided with the water outlet holes 1116. In this way, the liquid homogenizing member 1115 contributes to increasing the contact area between the liquid and the deaerator 11, prolonging the contact time between the liquid and the air, and contributing to efficiently precipitating the air in the liquid.
In some embodiments, the liquid-homogenizing member 1115 can be directly placed in the water tank body 1114, so that when liquid flows into the water tank body 1114 through the liquid-homogenizing member 1115, the liquid-homogenizing member 1115 floats on the liquid surface along with the increase of the liquid, thereby helping to ensure that the liquid flows through the liquid-homogenizing member 1115 uniformly and efficiently separating out air from the liquid. The liquid homogenizing member 1115 is directly placed in the water tank body 1114, which helps to simplify the structure of the degassing device 11, thereby facilitating the manufacture of the degassing device 11.
In this embodiment, the liquid inlet 1111 is located at the liquid homogenizing member 1115, and the liquid outlet 1112 and the air outlet 1113 are located at the water tank body 1114. The liquid inlet valve assembly 112 is connected to the liquid inlet end 1111, and the liquid inlet valve assembly 112 can selectively open or close the liquid inlet end 1111, so that when the liquid inlet valve assembly 112 selectively opens the liquid inlet end 1111, liquid can flow from the liquid inlet valve assembly 112 into the water tank body 1114 through the liquid inlet end 1111 on the liquid equalizing member 1115. The water outlet pump assembly 113 is connected to the water outlet end 1112, so that when the water outlet pump assembly 113 is operated, the water outlet pump assembly 113 can pump the liquid out of the degassing device 11 from the water outlet end 1112. Vent valve 114 is coupled to vent end 1113, and vent valve 114 selectively communicates with or blocks vent end 1113, so that gas may exit degasser 11 from vent valve 114 when vent valve 114 selectively communicates with vent end 1113. In this way, the heat exchanger unit 10 does not need to be provided with a vacuum pump for pumping, which is helpful for saving the manufacturing cost of the heat exchanger unit 10.
Wherein, the exhaust valve 114 may be an exhaust valve with a check function, or the degassing device 11 further comprises a one-way valve, and the exhaust valve 114 may be a common exhaust valve, which is connected to the exhaust end 1113 together with the one-way valve. In this way, it is helpful to avoid that ambient air enters the water tank 111 when the exhaust valve 114 is exhausted, thereby affecting the normal operation of the deaerator 11.
In the present embodiment, the liquid inlet valve assembly 112 includes a liquid inlet pipe 1121 and an electric valve 1122, the liquid inlet pipe 1121 is connected to the liquid inlet end 1111, the electric valve 1122 is provided in the liquid inlet pipe 1121, the liquid inlet pipe 1121 is provided with a liquid inlet port 1123, and the electric valve 1122 is located between the liquid inlet port 1123 and the liquid inlet end 1111 and selectively opens or closes the liquid inlet pipe 1121. Thus, when the electric valve 1122 is turned on to the liquid inlet pipe 1121, the liquid of the heat exchanger unit 10 can flow into the liquid inlet pipe 1121 through the liquid inlet port 1123, and at this time, the liquid inlet pipe 1121 supplies water to the water tank body 1114; when the electric valve 1122 closes the liquid inlet pipe 1121, the liquid in the heat exchanger unit 10 is blocked in the liquid inlet pipe 1121, and the liquid inlet pipe 1121 stops supplying water to the water tank body 1114.
The liquid inlet valve assembly 112 further includes a first switch valve 1124 and a first check valve 1125, where the first switch valve 1124 and the first check valve 1125 are both disposed on the liquid inlet pipe 1121, and the first switch valve 1124 is disposed between the liquid inlet 1123 and the electric valve 1122, and the first switch valve 1124 can selectively open or close the liquid inlet pipe 1121. Thus, when the first switching valve 1124 turns on the liquid inlet pipe 1121, the liquid of the heat exchanger unit 10 may flow into the liquid inlet pipe 1121 through the liquid inlet port 1123, and at this time, the liquid inlet pipe 1121 supplies water to the water tank body 1114; when the first on-off valve 1124 closes the liquid inlet pipe 1121, the liquid of the heat exchanger unit 10 is blocked in the liquid inlet pipe 1121, and the liquid inlet pipe 1121 stops supplying water to the water tank body 1114.
The first switch valve 1124 may maintain the state of opening the inlet conduit 1121, and selectively closes the inlet conduit 1121 when the degassing device 11 needs maintenance, thus helping to avoid leakage of the liquid in the heat exchanger unit 10. In addition, when the motor valve 1122 malfunctions, the deaerator 11 may maintain the normal operation of the deaerator 11 through the first switching valve 1124.
The first check valve 1125 is located between the electric valve 1122 and the fluid intake 1111, and the first check valve 1125 is configured to open the fluid intake conduit 1121 from the fluid intake 1123 toward the fluid intake 1111. In this way, the first check valve 1125 helps to ensure the flow direction of the liquid, and helps to avoid the reverse flow of the liquid, which would affect the normal operation of the motor-operated valve 1122.
In this embodiment, the water outlet pump assembly 113 includes a first water outlet pipe 1131 and a water outlet pump 1132, the first water outlet pipe 1131 is connected to the water outlet end 1112, the water outlet pump 1132 is disposed on the first water outlet pipe 1131, the first water outlet pipe 1131 is provided with a water outlet 1133, and the water outlet pump 1132 is disposed between the water outlet end 1112 and the water outlet 1133. The outlet pump 1132 has a pressurizing function that pumps the liquid such that the outlet pump 1132 pumps the liquid out of the outlet 1112 and into the heat exchanger unit 10 through the outlet 1133.
It should be noted that, when the water outlet pump assembly 113 is operated, the intake valve assembly 112 and the exhaust valve 114 stop operating, which helps to ensure that the water tank body 1114 is in a vacuum state.
The water outlet pump assembly 113 further includes a second switch valve 1134 and a second check valve 1135, where the second switch valve 1134 and the second check valve 1135 are both disposed on the first water outlet pipe 1131, the second switch valve 1134 is located between the water outlet pump 1132 and the water outlet end 1112, and the second switch valve 1134 can selectively communicate with or cut off the first water outlet pipe 1131. Thus, when the second switching valve 1134 is connected to the first water outlet pipeline 1131, the liquid in the water tank body 1134 can flow into the first water outlet pipeline 1131 from the liquid outlet end 1112 under the action of the water outlet pump 1132, and finally flows into the heat exchange unit 10 through the liquid outlet 1133; when the second switching valve 1134 closes the first water outlet pipe 1131, the water outlet pump assembly 113 operates, and the water inlet pipe 1121 supplies water to the water tank body 1114.
The second on-off valve 1134 may maintain the state of conducting the first water outlet conduit 1131, and when the degassing device 11 needs to be overhauled, the second on-off valve 1134 selectively cuts off the first water outlet conduit 1131, so as to help avoid leakage of the liquid in the heat exchange unit 10.
The second check valve 1135 is disposed between the water outlet pump 1132 and the liquid outlet 1133, and the second check valve 1135 is configured to conduct the first water outlet conduit 1131 from the liquid outlet end 1112 to the liquid outlet 1133. In this way, the second check valve 1135 helps to ensure the flow direction of the liquid, and helps to avoid the reverse flow of the liquid, which would affect the normal operation of the water pump 1132.
The water tank body 1114 is still equipped with body and goes out liquid end 1117, body goes out liquid end 1117 locates the top of water tank body 1114, go out water pump assembly 113 still includes second outlet conduit 1136 and third check valve 1137, second outlet conduit 1136 is connected in body and goes out liquid end 1117 and first outlet conduit 1131, third check valve 1137 locates second outlet conduit 1136, third check valve 1137 is located between body and goes out liquid end 1117 and the first outlet conduit 1131, third check valve 1137 is configured to switch on second outlet conduit 1136 from body play liquid end 1117 to the direction of first outlet conduit 1131, third check valve 1137 helps guaranteeing the flow direction of liquid, help avoiding liquid refluence and influencing degassing unit 11's normal work.
In this way, the deaerator 11 is provided with two water outlet pipes, when the water outlet pump 1132 or a device on the first water outlet pipe 1131 fails, the water outlet pump 1132 cannot pump the liquid in the water tank 1114 normally, and when the water tank 1114 is filled with the liquid, the second water outlet pipe 1136 can discharge the liquid through the liquid outlet 1133, so that the deaerator 11 can work normally.
In this embodiment, the exhaust end 1113 may be located at the top of the tank body 1114, and the liquid outlet end 1112 is located below the exhaust end 1113, for example, the liquid outlet end 1112 may be located at a side of the tank body 1114, so as to help maintain the normal operation of the degassing device 11.
The degasser 11 further includes a level sensor 115, the level sensor 115 being disposed on the tank body 1114, the level sensor 115 being capable of detecting the level of liquid in the tank body 1114. Illustratively, the liquid level sensor 115 is disposed on a side of the tank body 1114 facing away from the outlet end 1112, which helps to avoid large fluctuations in the liquid at the outlet end 1112 from affecting the accuracy of the liquid level sensor 115. The liquid level sensor 115 includes a first sensor 1151 and a second sensor 1152, the first sensor 1151 is disposed near a top of the tank body 1114 relative to a bottom of the tank body 1114, the second sensor 1152 is disposed near the bottom of the tank body 1114 relative to the top of the tank body 1114, and the first sensor 1151 and the second sensor 1152 cooperate to detect a height of liquid in the tank body 1114.
The water tank body 1114 is provided with a first preset water level and a second preset water level, and the second preset water level is the water level of the full water of the water tank body 1114. When the liquid level sensor 115 detects that the liquid in the water tank body 1114 is lower than a first preset water level, the liquid level sensor 115 displays a low liquid level and gives an alarm; when the liquid level sensor 115 detects that the liquid in the tank body 1114 reaches a second preset level, the liquid level sensor 115 will display a high liquid level and alarm. In this manner, monitoring the level of liquid in tank body 1114 by level sensor 115 helps ensure proper operation of deaerator 11.
In the present embodiment, the liquid level sensor 115 is linked to the electric valve 1122 and the water outlet pump 1132. For example, the fluid level sensor 115 may be in signal connection with the electrically operated valve 1122 and the water outlet pump 1132. When the liquid in the water tank body 1114 is lower than a first preset water level, the liquid level sensor 115 displays a low liquid level and gives an alarm, and at the moment, the liquid level sensor 115 sends a first signal, the electric valve 1122 receives the first signal and conducts the liquid inlet pipe 1121, and the liquid inlet pipe 1121 supplies water to the water tank body 1114; the water outlet pump 1132 receives the first signal, the water outlet pump 1132 stops working, the first water outlet pipe 1131 is cut off, and the water tank body 1114 starts storing water.
Along with the inflow of the liquid, when the liquid in the water tank body 1114 reaches a second preset water level, the liquid level sensor 115 displays a high liquid level and gives an alarm, at this time, the water tank body 1114 is filled with water, the liquid level sensor 115 sends a second signal, the electric valve 1122 receives the second signal and cuts off the liquid inlet pipe 1121, and the liquid inlet pipe 1121 stops supplying water to the water tank body 1114; the water outlet pump 1132 receives the second signal, the water outlet pump 1132 works, and the liquid in the water tank body 1134 can flow into the first water outlet pipeline 1131 from the liquid outlet end 1112 under the action of the water outlet pump 1132, and finally flows into the heat exchanger unit 10 through the liquid outlet 1133.
As the liquid in the tank body 1114 is gradually pumped away, the space in the upper portion of the tank body 1114 gradually increases, forming a vacuum environment. When the liquid in the water tank body 1114 is lower than the first preset water level, the liquid level sensor 115 re-sends the first signal, the electric valve 1122 receives the first signal and conducts the liquid inlet pipe 1121, the water outlet pump 1132 receives the first signal and stops working, the liquid flowing into the water tank body 1114 enters a negative pressure environment, the pressure is lower, the solubility of the gas can be reduced, free and dissolved gas in the liquid can be automatically separated out, the vacuum degassing process is completed, and a cycle is formed. After the liquid is circulated repeatedly through the heat exchanger unit 10 and the deaerator 11 for a plurality of times, the liquid entering the water tank body 1114 gradually precipitates air therein in the negative pressure vacuum environment, and when the air precipitated in the deaerator 11 is accumulated to a certain extent, the exhaust valve 114 is automatically opened, and then the air in the deaerator 11 is discharged.
In this embodiment, the degasser 11 further comprises a differential pressure sensor 116, the differential pressure sensor 116 being connected between the top of the tank body 1114 and the inlet 1123. The differential pressure sensor 116 may detect a pressure differential between the water tank body 1114 and the inlet conduit 1121, and the differential pressure sensor 116 may be a micro-differential pressure sensor, a pressure sensor, or others. When the differential pressure sensor 116 shows that the differential pressure is 0, the water tank body 1114 is filled with water, so that the water tank body 1114 is filled with liquid in the liquid feeding process, the residual gas in the top space of the water tank body 1114 is avoided, and the total discharge of the gas in the water tank body 1114 is ensured. In this manner, the differential pressure sensor 116 may assist the liquid level sensor 115 in detecting whether the tank body 1114 is full of water, thereby maintaining efficient operation of the degasser 11.
In summary, according to the deaerator 11 and the heat exchanger unit 10 provided by the invention, the water tank 111 is provided with the liquid inlet end 1111, the liquid outlet end 1112 and the air exhaust end 1113, so that the deaerator 11 can realize liquid inlet through the liquid inlet end 1111, the deaerator 11 can realize liquid outlet through the liquid outlet end 1112, and the deaerator 11 can realize air exhaust through the air exhaust end 1113. The water tank 111 includes water tank body 1114 and equal liquid spare 1115, and equal liquid spare 1115 assembles in water tank body 1114, and equal liquid spare 1115 is equipped with a plurality of apopores 1116, and apopores 1116 are located between the bottom and the top of water tank body 1114, then equal liquid spare 1115 helps increasing the area of contact of liquid and degasser 11, prolongs the contact time of liquid and air, helps the air in the high-efficient precipitation liquid. The liquid inlet 1111 is located at the liquid equalizing member 1115, the liquid outlet 1112 and the air outlet 1113 are located at the water tank body 1114, the liquid inlet valve assembly 112 is connected to the liquid inlet 1111, and the liquid inlet valve assembly 112 can selectively open or close the liquid inlet 1111, so that when the liquid inlet valve assembly 112 selectively opens the liquid inlet 1111, liquid can flow from the liquid inlet valve assembly 112 into the water tank body 1114 through the liquid inlet 1111 of the liquid equalizing member 1115. The water outlet pump assembly 113 is connected to the water outlet end 1112, so that when the water outlet pump assembly 113 is operated, the water outlet pump assembly 113 can pump the liquid out of the degassing device 11 from the water outlet end 1112. Vent valve 114 is coupled to vent end 1113, and vent valve 114 selectively communicates with or blocks vent end 1113, so that gas may exit degasser 11 from vent valve 114 when vent valve 114 selectively communicates with vent end 1113. In this way, the heat exchanger unit 10 does not need to be provided with a vacuum pump for pumping, which contributes to saving the manufacturing cost.
