Description

Technical Field

[0001] This application relates to the field of cooling technology, and in particular to an energy exchange device and cooling system for absorbing pulse loads. Background Technology

[0002] For intermittently operating cooling equipment, pulse loads (such as cooling or heating loads) are generated during its operation. To coordinate the connection between the pulse loads and the continuously operating cooling source, a device that absorbs the pulse loads is usually configured.

[0003] However, existing equipment for absorbing pulsed loads cannot respond quickly enough to absorb them. Summary of the Invention

[0004] This application provides an energy exchange device and a cooling system for absorbing pulse loads, so as to respond quickly to pulse loads.

[0005] This application provides an energy exchange device for absorbing pulsed loads, comprising:

[0006] The tank body is equipped with a fluid inlet and a fluid outlet, the fluid inlet and the fluid outlet being located at opposite ends of the tank body;

[0007] The impeller is rotatably mounted in the tank and positioned near the fluid inlet.

[0008] Based on the above technical solution, the fluid inlet of the tank can be connected to a pipeline carrying a relatively high-temperature fluid, and the fluid outlet can be connected to a pipeline carrying a relatively low-temperature fluid. When the relatively high-temperature fluid enters the tank through the fluid inlet, the conversion between static and dynamic pressure drives the impeller to rotate, thereby allowing the relatively high-temperature fluid to diffuse to all parts of the tank, mixing with the relatively low-temperature fluid to achieve the absorption of pulse loads. In other words, the energy exchange device for absorbing pulse loads provided in this application can mix the relatively high-temperature fluid with the relatively low-temperature fluid immediately after it enters the tank, enabling rapid absorption of pulse loads.

[0009] In some possible implementations, the fluid inlet is located below the fluid outlet in the direction of gravity.

[0010] In some possible implementations, the energy exchange device for absorbing pulsed loads further includes at least two rectifier orifice plates, which are arranged sequentially at intervals from the impeller to the fluid outlet, and each of the rectifier orifice plates is provided with a plurality of flow holes;

[0011] In two adjacent rectifier orifice plates, the diameter of the flow passage in the rectifier orifice plate closer to the impeller is larger than the diameter of the flow passage in the rectifier orifice plate farther from the impeller.

[0012] In some possible implementations, the energy exchange device for absorbing pulsed loads includes a first rectifier plate and a second rectifier plate, wherein the first rectifier plate is located on the side of the second rectifier plate closer to the impeller;

[0013] The first rectifier plate has multiple first flow holes, and the second rectifier plate has multiple second flow holes. The diameter of the first flow holes is larger than the diameter of the second flow holes.

[0014] In some possible implementations, the plurality of flow holes are evenly distributed in the same rectifier plate.

[0015] In some possible implementations, the energy exchange device for absorbing pulsed loads further includes a shunt pipe;

[0016] The diversion pipe is disposed in the tank and communicates with the fluid inlet. Multiple diversion holes are evenly opened on the periphery of the diversion pipe, and the multiple diversion holes are all communicated with the fluid inlet and the interior of the tank.

[0017] The impeller is rotatably mounted at the end of the distributor pipe away from the fluid inlet.

[0018] In some possible implementations, the impeller is coaxially arranged with the diverter.

[0019] In some possible implementations, the energy exchange device for absorbing pulsed loads further includes a flow guide ring, which is disposed around the periphery of the shunt tube and is spaced apart from the shunt tube.

[0020] In some possible implementations, the impeller is rotatably mounted on the diverter via a bearing, and the end of the diverter away from the fluid inlet is sealed.

[0021] In addition, this application also provides a cooling system, including the energy exchange device for absorbing pulse loads as described in the above embodiments. Attached Figure Description

[0038] The embodiment provides an energy exchange device for absorbing pulse loads, which can be connected to the piping of a cooling system to quickly absorb pulse loads.

[0039] like Figure 1 and Figure 2 As shown, the energy exchange device for absorbing pulsed loads includes a tank 100 and an impeller 200.

[0040] One end of the tank 100 may be provided with a fluid inlet 101, and the other end of the tank 100 may be provided with a fluid outlet 102. That is, the fluid inlet 101 and the fluid outlet 102 are respectively located at the two ends of the tank 100.

[0041] In this embodiment, the fluid inlet 101 can be used to connect a pipeline to a fluid with a relatively high temperature, and the fluid outlet 102 can be used to connect a pipeline to a fluid with a relatively low temperature.

[0042] It is understood that the fluid can flow inside the tank 100 and can flow from the fluid inlet 101 to the fluid outlet 102.

[0043] In this embodiment, the impeller 200 is rotatably mounted inside the tank 100. Furthermore, the impeller 200 can be positioned near the fluid inlet 101.

[0044] During use, a portion of the fluid with a relatively low temperature may exist inside the tank 100. A relatively high-temperature fluid may enter the tank 100 through the fluid inlet 101. When the relatively high-temperature fluid enters the tank 100, it pushes the fluid flow within the pipe, thereby driving the impeller 200 to rotate under the action of static and dynamic pressure conversion. Thus, under the rotation of the impeller 200, the relatively high-temperature fluid can flow within the tank 100, allowing it to mix with the relatively low-temperature fluid in the tank 100, thus absorbing pulse loads.

[0045] In this application, when a relatively high-temperature fluid enters the tank 100, it can mix with a relatively low-temperature fluid inside the tank 100 to absorb pulse loads, thus achieving rapid response absorption of pulse loads.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the tank 100 may further include a tank body 110, a first transfer pipe 120, and a second transfer pipe 130.

[0047] The first adapter pipe 120 may be disposed at one end of the tank body 110 and may communicate with the interior of the tank body 110. The fluid inlet 101 may be formed at the end of the first adapter pipe 120 away from the tank body 110. The second adapter pipe 130 may be disposed at the end of the tank body 110 away from the first adapter pipe 120 and may communicate with the interior of the tank body 110. The fluid outlet 102 may be formed at the end of the second adapter pipe 130 away from the tank body 110.

[0048] In some embodiments, the first transfer pipe 120 and the second transfer pipe 130 can both be fixedly connected to the tank body 110 by welding.

[0049] In other embodiments, the first transfer pipe 120, the second transfer pipe 130, and the tank body 110 may also be an integral structure.

[0050] In some embodiments, the fluid inlet 101 may be located below the fluid outlet 102 in the direction of gravity. When a relatively hot fluid enters the tank body 110 through the fluid inlet 101, its density will be less than the density of the relatively cool fluid in the tank body 110. As a result, the relatively hot fluid can generate buoyancy and move upward toward the fluid outlet 102.

[0051] In this embodiment, the impeller 200 may be disposed in the tank body 110.

[0052] Combined again Figure 3 The energy exchange device for absorbing pulsed loads also includes a diverter pipe 300. The diverter pipe 300 can be disposed within the tank body 110 and can be located at one end of the tank body 110 near the first transfer pipe 120. In some embodiments, one end of the diverter pipe 300 can be in communication with the first transfer pipe 120. In some embodiments, the diverter pipe 300 and the first transfer pipe 120 can be an integral structure.

[0053] In other embodiments, the diversion pipe 300 may also be fixedly connected to the first transfer pipe 120 by means of welding or other methods.

[0054] In this embodiment, the impeller 200 can be rotatably mounted on the end of the diversion pipe 300 away from the first transfer pipe 120 via the bearing 400, and can close the end of the diversion pipe 300 away from the first transfer pipe 120. Furthermore, the rotation axis of the impeller 200 can coincide with the axis of the diversion pipe 300, and the impeller 200 can be coaxially arranged with the diversion pipe 300.

[0055] In some embodiments, a plurality of diversion holes 310 may be formed on the periphery of the diversion pipe 300, and the plurality of diversion holes 310 may be evenly distributed at intervals along the periphery of the diversion pipe 300. It is understood that the diversion holes 310 may communicate with the interior of the tank body 110. The first adapter pipe 120 may communicate with the interior of the tank body 110 through the diversion holes 310, allowing fluid to pass through. The fluid in the diversion pipe 300 may flow out through the diversion holes 310 on the periphery of the diversion pipe 300.

[0056] In this embodiment, when fluid enters the internal space of the tank body 110 through the diversion pipe 300, the multiple diversion holes 310 can divert the fluid, so that the fluid is evenly distributed to various positions on the periphery of the tank body 110, thereby improving the diffusion effect.

[0057] It is understandable that the impeller 200 and the diverter pipe 300 are coaxially arranged so that the fluid output from the diverter pipe 300 is evenly distributed relative to the periphery of the impeller 200, and also ensures that the force on each part of the impeller 200 is uniform, thus ensuring that the impeller 200 rotates smoothly.

[0058] like Figure 2 and Figure 3 As shown, the energy exchange device for absorbing pulsed loads also includes a flow guide ring 500. The flow guide ring 500 can be disposed inside the tank body 110 and located at one end of the tank body 110 near the diversion pipe 300. In the embodiment, the flow guide ring 500 can be disposed around the periphery of the diversion pipe 300, and the flow guide ring 500 can be disposed at intervals from the diversion pipe 300.

[0059] When fluid flows into the internal space of the tank body 110 through the diversion hole 310 of the diversion pipe 300, the guide ring 500 can guide the fluid, changing the flow direction of the fluid so that the flow direction is towards the impeller 200. At the same time, the guide ring 500 can also make the fluid more evenly dispersed around the diversion pipe 300, thereby making the fluid pressure distribution around the diversion pipe 300 more uniform, and also ensuring that the force on each part of the impeller 200 is more uniform, so that the impeller 200 can rotate smoothly.

[0060] It is understandable that there is a gap between the end face of the guide ring 500 away from the first transfer tube 120 and the impeller 200, which can avoid interfering with the rotation of the impeller 200.

[0061] like Figure 2 As shown, the energy exchange device for absorbing pulsed loads further includes at least two rectifier orifice plates 600. These at least two rectifier orifice plates 600 can be disposed within the tank body 110 and can be sequentially arranged from the end near the impeller 200 to the end near the fluid outlet 102. Furthermore, adjacent rectifier orifice plates 600 can be spaced apart.

[0062] In some embodiments, the energy exchange device for absorbing pulsed loads further includes two rectifier orifice plates 600, namely a first rectifier orifice plate 610 and a second rectifier orifice plate 620. The first rectifier orifice plate 610 may be located on the side of the second rectifier orifice plate 620 closer to the impeller 200. Furthermore, the first rectifier orifice plate 610 is spaced apart from the impeller 200.

[0063] In addition, the first rectifier orifice plate 610 may have a plurality of first flow passages 611, which may be evenly distributed on the first rectifier orifice plate 610. The second rectifier orifice plate 620 may include a plurality of second flow passages 621, which may be evenly distributed on the second rectifier orifice plate 620.

[0064] In this embodiment, the diameter of the first flow-through orifice 611 may be larger than the diameter of the second flow-through orifice 621. In some embodiments, for example, the diameter of the first flow-through orifice 611 may be set to 7 mm, and the diameter of the second flow-through orifice 621 may be set to 5 mm.

[0065] Of course, in other embodiments, the diameter of the first flow hole 611 can also be set to 6mm or the diameter of the second flow hole 621 can be set to 4mm or the diameter of the second flow hole 621.

[0066] In other embodiments, the energy exchange device for absorbing pulsed loads may also include three or four equal numbers of rectifier orifice plates 600. The plurality of rectifier orifice plates 600 may be arranged sequentially along the direction from the impeller 200 to the fluid outlet 102. Furthermore, in adjacent pairs of rectifier orifice plates 600, the diameter of the flow-through orifice 601 on the rectifier orifice plate 600 closer to the impeller 200 may be larger than the diameter of the flow-through orifice 601 on the rectifier orifice plate 600 farther from the impeller 200.

[0067] During operation, a relatively high-temperature fluid is input through the first transfer pipe 120 and dispersed to various parts around the tank body 110 via the distribution pipe 300. After the fluid exits through the distribution pipe 300, it is guided by the flow guide ring 500, thereby changing the flow direction of this portion of the fluid and directing it towards the impeller 200. Simultaneously, the fluid is further dispersed by the flow guide ring 500, achieving a more uniform distribution around the distribution pipe 300. Consequently, the fluid pressure distribution around the distribution pipe 300 becomes more uniform, resulting in more even force distribution across the impeller 200 and ensuring smooth rotation of the impeller 200.

[0068] Furthermore, when a relatively high-temperature fluid enters the tank body 110, it can drive the flow of a relatively low-temperature fluid within the tank body 110. During the conversion between static and dynamic pressure, this drives the impeller 200 to rotate. Thus, during the rotation of the impeller 200, the relatively high-temperature fluid and the relatively low-temperature fluid can be mixed, thereby achieving the absorption of pulse loads.

[0069] Furthermore, due to the centrifugal force from the rotating impeller 200 and the buoyancy generated by the density difference, the fluid's trajectory within the tank body 110 generally exhibits a spiral upward motion. It is understood that the fluid temperature near the fluid inlet 101 will be relatively higher, while the temperature further away from the inlet 101 will be relatively lower, and the density of the hotter fluid is less than that of the colder fluid. Therefore, the relatively hotter fluid will experience buoyancy upon entering the tank body 110, causing it to rise.

[0070] In this embodiment, during the spiral ascent of the fluid, the fluid density near the center of the vortex is lower than that at the edge, creating a density difference. In this embodiment, the first rectifier plate 610 can perform primary rectification of the rising fluid, reducing the density difference between different parts of the rising fluid and balancing the density difference between the center and edge positions within the tank body 110.

[0071] In this embodiment, the second rectifier plate 620 can perform secondary rectification of the rising fluid, further equalize the density difference between the center and edge positions within the tank body 110, and enable the fluid output through the fluid outlet 102 to be converted from dynamic pressure to static pressure as much as possible, so that it can enter the downstream pipe of the cooling system to continue to provide cooling function.

[0072] The embodiment also provides a cooling system, which may include the energy exchange device for absorbing pulse loads provided in the embodiment.
