Description

Technical Field

[0001] This application belongs to the technical field of flow guiding equipment, and particularly relates to an upper cold water flow guiding device and a strip steel cooling system. Background Technology

[0002] Steel strip is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Steel strip is also known as steel strip. According to the rolling method, steel strip can be divided into two types: hot-rolled and cold-rolled, which are respectively called hot-rolled steel strip and cold-rolled steel strip.

[0003] To reduce strip deformation and cracking, a layer cooling process is required during the production of hot-rolled strip.

[0004] In related technologies, after strip steel undergoes a layer cooling process, defects such as edge cracks and edge waviness often occur, which seriously affect the strip steel yield and downstream process production, becoming a problem that plagues the industry. Utility Model Content

[0007] A first flow guide has a converging channel and a diverting channel that are connected. The converging channel extends along a first direction and is located below one side of a plurality of the upper cooling manifolds along a second direction. The diverting channel extends along the second direction and is located below the spacer area between two adjacent upper cooling manifolds. The first direction and the second direction are perpendicular. The first outlet of the diverting channel is located at the end of the diverting channel away from the converging channel.

[0008] A connecting mechanism is connected to the upper cooling manifold and the first flow guide.

[0009] In some embodiments, the upper cold water guiding device further includes a second guiding member, which is connected to the connecting mechanism and disposed on the side of the diversion channel away from the aggregation channel. The second guiding member has a guiding channel, which is disposed below the upper cold water manifold on the other side along the second direction. The second liquid outlet of the guiding channel is disposed on the side of the guiding channel away from the aggregation channel.

[0010] In some embodiments, the second guide member further includes a receiving groove, which is disposed below the first liquid outlet, and a third liquid outlet of the receiving groove is disposed on the side of the receiving groove away from the converging groove.

[0011] In some embodiments, the connection mechanism includes:

[0012] The supporting body is connected to the upper cooling manifold;

[0013] A first connecting component is slidably connected to the support body along the second direction;

[0014] The second connecting component is slidably connected to the support body along the second direction.

[0015] In some embodiments, the upper cold water diversion device further includes a driving component, which is installed on the support body. The output end of the driving component is connected to the first connecting component and / or the second connecting component to drive the first connecting component and the second connecting component to slide along the second direction.

[0016] In some embodiments, the driving component includes:

[0017] The first gear and the second gear are spaced apart along the second direction and are both rotatably connected to the support body;

[0018] A chain, connected to the first gear and the second gear, and the chain connects the first connecting assembly and the second connecting assembly;

[0019] A drive element is installed on the support body, and the drive element drives the first gear and / or the second gear to rotate.

[0020] In some embodiments, the chain has a first straight segment and a second straight segment, the first connecting component is connected to one of the first straight segment and the second straight segment, and the second connecting component is connected to the other.

[0021] In some embodiments, the support body is provided with a guide portion extending in a second direction, and the first connecting component includes:

[0022] The first roller is located on the guide portion and makes rolling contact with the guide portion;

[0023] The first pull rod is located between the first roller and the first guide member, and is fixedly connected to the first guide member and rotatably connected to the first roller.

[0024] In some embodiments, the support body is provided with a guide portion extending in a second direction, and the second connecting component includes:

[0025] The second roller is located on the guide portion and makes rolling contact with the guide portion;

[0026] The second pull rod is located between the second roller and the second guide member, and is fixedly connected to the second guide member and rotatably connected to the second roller.

[0027] Secondly, an embodiment of this application provides a strip cooling system, comprising:

[0029] A cooling manifold is installed above the roller conveyor;

[0030] The upper cold water diversion device described in the first aspect is connected to the upper cold water manifold via a connecting mechanism.

[0031] This utility model has at least the following beneficial effects:

[0032] On the one hand, the upper layer of cold water discharged from the upper manifold of the laminar flow cooling system will fall into the flow collection channel and enter the flow diversion channel along the flow collection channel, and then be discharged to the outside of the strip steel along the flow diversion channel, thereby reducing the temperature drop at the edge of the strip steel. This solves the problems of edge cracks and edge waves caused by excessively fast and uneven cooling at the edge of the strip steel, and helps to improve the quality of the strip steel.

[0033] On the other hand, the flow collection tank can collect the upper chilled water discharged from one side of multiple upper chilled manifolds at the same time, without having to install an upper chilled water guide device on each upper chilled manifold. This will help reduce the number of upper chilled water guide devices and save production costs for enterprises.

[0034] On the other hand, the upper cold water collected from one side of the upper cooling manifold by the first guide component will be discharged from the first liquid outlet located on the other side of the upper cooling manifold. This will help to allow the water flow on both sides of the upper cooling manifold to be discharged from one side at the same time. With this design, devices such as motors that cannot come into contact with water can be placed below the flow collection tank on one side to prevent water from falling on them. This will effectively protect these devices from water damage and ensure the stable operation of the strip steel production line. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0044] The inventors discovered that the main reason for edge cracking and edge waviness in strip steel is that, in related technologies, in order to adapt the laminar cooling device to strip steel of different widths, the upper layer of cold water sprayed from the upper manifold of the laminar cooling device covers a wide range. This results in the upper layer of cold water sprayed on both sides of the upper manifold along the 400mm width direction of the strip steel when producing strip steel with a smaller width, causing the temperature of the 400mm edge of the strip steel to drop rapidly. The excessively low temperature of the 400mm edge of the strip steel causes a phase transformation in the strip steel structure, thus leading to frequent edge cracking and edge waviness.

[0045] Therefore, in related technologies, strip steel often suffers from defects such as edge cracks and edge waviness after layer cooling. This application provides an upper-layer cold water guiding device and a strip steel cooling system, which can at least partially solve the technical problem of edge cracks and edge waviness frequently occurring in strip steel after layer cooling.

[0046] The upper cold water guiding device 100 of this application guides the upper cold water discharged from both sides of the upper cold manifold 200 to the outside of the strip steel through the first guiding element 110 and the second guiding element 140, so as to prevent the upper cold water discharged from both sides of the upper cold manifold 200 from falling on the edge of the strip steel 400, reduce the temperature drop at the edge of the strip steel, and thus improve the problems of edge cracking and edge waviness of the strip steel.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] like Figure 1As shown, the upper cold water guiding device 100 is used to guide the upper cold water on both sides of the upper cooling manifold 200. The upper cold water guiding device 100 includes a first guiding member 110 and a connecting mechanism 120. The first guiding member 110 has a converging channel 110a and a guiding channel 110b that are connected. The converging channel 110a extends along a first direction and is located below one side of multiple upper cooling manifolds 200 along a second direction. The guiding channel 110b extends along the second direction and is located below the interval area between two adjacent upper cooling manifolds 200. The first direction and the second direction are perpendicular. The first outlet 110b1 of the guiding channel 110b is located at the end of the guiding channel 110b away from the converging channel 110a. The connecting mechanism 120 connects the upper cooling manifold 200 and the first guiding member 110.

[0049] like Figure 2 As shown, during the laminar cooling of the strip 400, the strip 400 is located below the laminar cooling upper manifold 200 and is conveyed through the lower roller conveyor 300. The laminar cooling upper manifold 200 sprays upper-layer cold water downwards, which is sprayed onto the upper surface of the strip 400. Multiple laminar cooling upper manifolds 200 are spaced apart above the roller conveyor 300 along its length direction, and the laminar cooling upper manifolds 200 extend along the width direction of the roller conveyor 300. In use, the connecting mechanism 120 is connected to both the laminar cooling upper manifold 200 and the first guide member 110. The first direction is parallel to the length direction of the roller conveyor 300, and the second direction is parallel to the width direction of the roller conveyor 300, that is, parallel to the extension direction of the laminar cooling upper manifold 200.

[0050] The connecting mechanism 120 carries the first flow guide 110, enabling the first flow guide 110 to be stably positioned below the laminar cooling upper manifold 200. The connection mechanism 120 to the laminar cooling upper manifold 200 and the first flow guide 110 can be made in various ways, such as snap-fit, bolt connection, or binding connection, and is not limited in this application. In some embodiments, the connecting mechanism 120 is connected to the laminar cooling water beam of the laminar cooling upper manifold 200.

[0051] The collecting tank 110a is connected to the diversion tank 110b, and the first outlet 110b1 of the diversion tank 110b is located at the end of the diversion tank 110b away from the collecting tank 110a. This allows the water collected in the collecting tank 110a to enter the diversion tank 110b and flow along the diversion tank 110b, and be discharged from the end of the diversion tank 110b away from the collecting tank 110a.

[0052] The flow collection tank 110a extends along the first direction and is located below one side of the multiple chilled manifolds 200 along the second direction, so that the flow collection tank 110a can simultaneously collect the upper chilled water discharged from one side of the multiple chilled manifolds 200.

[0053] The drainage channel 110b extends along the second direction and is located below the interval area between two adjacent upper cooling manifolds 200, so that the drainage channel 110b is not located below the upper cooling manifold 200, so as to avoid the drainage channel 110b interfering with the upper cooling water discharged from the middle area of ​​each upper cooling manifold 200 falling onto the strip 400, ensuring that the upper cooling water discharged from the middle area of ​​the upper cooling manifold 200 can fall onto the surface of the strip 400 to cool the strip.

[0054] The flow-gathering channel 110a is located below one side of the upper cooling manifold 200 along the second direction, and the flow-guiding channel 110b is located below the interval area between two adjacent upper cooling manifolds 200. The first liquid outlet 110b1 of the flow-guiding channel 110b is located at the end of the flow-guiding channel 110b away from the flow-gathering channel 110a. This will cause the upper layer of cold water discharged from one side of the upper cooling manifold 200 to enter the first guide member 110 and then be discharged from the first liquid outlet 110b1 located on the other side of the upper cooling manifold 200.

[0055] The upper cold water diversion device 100 is designed as described above:

[0056] On the one hand, the upper layer of cold water discharged from one side of the upper cooling manifold 200 will fall into the gathering groove 110a, and enter the guiding groove 110b along the gathering groove 110a, and then be discharged to the outside of the strip 400 along the guiding groove 110b, thereby reducing the temperature drop at the edge of the strip 400. This solves the problems of edge cracks and edge waves caused by the excessively fast and uneven cooling at the edge of the strip 400, and helps to improve the quality of the strip.

[0057] On the other hand, the collecting tank 110a can collect the upper cold water discharged from one side of multiple upper cooling manifolds 200 at the same time, without having to install an upper cold water guiding device 100 on each upper cooling manifold 200. This will help reduce the number of upper cold water guiding devices 100 and save the company's production costs.

[0058] On the other hand, the upper cold water collected by the first guide element 110 from one side of the upper cooling manifold 200 will be discharged from the first outlet 110b1 located on the other side of the upper cooling manifold 200. This will help to allow the water flow on both sides of the upper cooling manifold 200 to be discharged from one side at the same time. With this design, devices such as motors that cannot come into contact with water can be placed below the side of the flow collection tank 110a to prevent water from falling on them. This will effectively protect these devices from water damage and ensure the stable operation of the strip steel production line.

[0059] In order to improve the flow rate of water in the first guide member 110, in some embodiments, both the gathering channel 110a and the diversion channel 110b are inclined. The side of the gathering channel 110a away from the diversion channel 110b is higher and the side of the diversion channel 110b is lower. The side of the diversion channel 110b near the gathering channel 110a is higher and the side away from the gathering channel 110a is lower.

[0060] In some embodiments, the upper cold water guiding device 100 further includes a second guiding member 140, which is connected to the connecting mechanism 120 and is disposed on the side of the guiding channel 110b away from the gathering channel 110a. The second guiding member 140 has a guiding channel 140a, which is disposed below the other side of the upper cooling manifold 200 along the second direction. The second outlet 140b of the guiding channel 140a is disposed on the side of the guiding channel 140a away from the gathering channel 110a.

[0061] The connecting mechanism 120 is also connected to the second guide member 140 so that the second guide member 140 can be stably positioned below the laminar cooling upper manifold 200. The connection between the connecting mechanism 120 and the second guide member 140 can be a snap-fit ​​connection, a bolt connection, a binding connection, etc., which is not limited in this application. The function of the guide channel 140a is to receive the upper layer of cold water discharged from the other side of the laminar cooling upper manifold 200 and guide the upper layer of cold water to be discharged outside the strip 400. Specifically, the guide channel 140a has a second outlet 140a1, and the upper layer of cold water that falls into the guide channel 140a from the laminar cooling upper manifold 200 will be discharged outside the strip through the second outlet 140a1. With this design, the flow-gathering channel 110a and the flow-guiding channel 140a are respectively located on both sides of the upper cooling manifold 200 along the second direction. The flow-gathering channel 110a collects the upper cooling water on one side of the upper cooling manifold 200 along the second direction, and the flow-guiding channel 140a collects the upper cooling water on the other side of the upper cooling manifold 200 along the second direction. The upper cooling water on both sides of the upper cooling manifold 200 is collected and guided to the outside of the strip 400 at the same time. This also improves the problems of edge cracks and edge waves caused by excessively fast cooling and uneven cooling on both sides of the strip 400, which helps to improve the quality of the strip.

[0062] The number of guide channels 140a can be one or more, and is not limited in this application. When one guide channel 140a is provided, the guide channel 140b can extend along the first direction to simultaneously guide the upper cold water discharged from one side of multiple upper cold water guide devices 100. When multiple guide channels 140a are provided, the multiple guide channels 140b can be arranged at intervals along the first direction and located below each upper cold water guide device 100 to guide the upper cold water discharged from one side of multiple upper cold water guide devices 100 respectively.

[0063] In order to increase the flow rate of water in the second guide member 140, in some embodiments, the guide channel 140a is inclined, with the side of the guide channel 140a away from the diversion channel 110b being lower and the side closer to the diversion channel 110b being higher.

[0064] In some embodiments, the diversion channel 110b is disposed in the middle of the convergence channel 110a, and the second guide member 140 is T-shaped.

[0065] In some embodiments, the second guide member 140 further includes a receiving groove 140b, which is disposed below the first liquid outlet 110b1, and the third liquid outlet 140b1 of the receiving groove 140b is disposed on the side of the receiving groove 140b away from the converging groove 110a.

[0066] The receiving channel 140b is located below the first outlet 110b1, allowing the water discharged from the first outlet 110b1 to enter the receiving channel 140b and flow along it before finally exiting from the third outlet 140b1. This design ensures that all water is ultimately discharged through the second guide member 140, facilitating the installation of drainage channels below the second guide member 140. Furthermore, this design allows the first outlet 110b1 to remain above the receiving channel 140b within a certain range of movement, even when the first guide member 110 is adjusted away from the second guide member 140, ensuring the water can be smoothly discharged to the outside of the strip.

[0067] In some embodiments, two flow guide channels 140a and one flow receiving channel 140b are provided, with the flow receiving channel 140b located between the two flow guide channels 140a.

[0068] In some embodiments, the connecting mechanism 120 includes a support body 121, a first connecting component 122, and a second connecting component 123. A first guide member 110 is connected to the first connecting component 122, and the first connecting component 122 is slidably connected to the support body 121 along a second direction. A second guide member 140 is connected to the second connecting component 123, and the second connecting component 123 is slidably connected to the support body 121 along a second direction.

[0069] The first connecting component 122 is connected to both the support body 121 and the first flow guide 110; the second connecting component 123 is connected to both the support body 121 and the second flow guide 140; the support body 121 is connected to the upper cooling manifold 200. The connection methods are varied, such as bonding, welding, and snap-fitting. With this design, the first connecting component 122 and the second connecting component 123 can move along the second direction, thereby driving the first flow guide 110 and the second flow guide 140 to move along the second direction. This allows the positions of the flow collection channel 110a and the flow guide channel 140a to be adaptively changed according to the location of the edge of the strip steel 400, facilitating the use of the upper cooling water flow guide device 100.

[0070] In some embodiments, the upper cold water diversion device 100 further includes a drive component 130, which is mounted on the support body 121. The output end of the drive component 130 is connected to the first connection component 122 and / or the second connection component 123 to drive the first connection component 122 and the second connection component 123 to slide along the second direction.

[0071] The output terminal of the drive component 130 can be connected to the first connecting component 122, the second connecting component 123, or both simultaneously. When the drive component 130 is connected to both the first and second connecting components 122 and 123, it can drive them to move in the same direction (i.e., simultaneously along one side of a first direction); or it can drive them to move in opposite directions (i.e., towards or away from each other). With the drive component 130 installed, the positions of the first and / or second connecting components 122 and 123 can be adjusted by controlling the operation of the drive component 130, facilitating the use of the upper cold water diversion device 100.

[0072] The structure of the drive assembly 130 is varied and is not limited in this application. It can be a hydraulic cylinder, with the lever as the output end. The hydraulic cylinder is arranged along the second direction, and the lever head is connected to the first connecting assembly 122 and / or the second connecting assembly 123, thereby driving the first connecting assembly 122 and / or the second connecting assembly 123 to slide in the second direction. The drive assembly 130 may also include a motor and a lead screw and nut pair. The nut is slidably connected to the support body 121 along the second direction, the motor is mounted on the support body 121, and the lead screw is rotatably connected to the support body 121. The lead screw is arranged along the second direction, and the first connecting assembly 122 and / or the second connecting assembly 123 is connected to the lead screw. The motor drives the lead screw to rotate, thereby driving the nut to move along the second direction, and thus driving the first connecting assembly 122 and / or the second connecting assembly 123 to move along the second direction.

[0073] In some embodiments, the drive assembly 130 includes a first gear 131, a second gear 132, a chain 133, and a drive element 134. The first gear 131 and the second gear 132 are spaced apart along a second direction and are both rotatably connected to the support body 121. The chain 133 is connected to the first gear 131 and the second gear 132, and the chain 133 is connected to the first connecting assembly 122 and the second connecting assembly 123. The drive element 134 is mounted on the support body 121 and drives the first gear 131 and / or the second gear 132 to rotate.

[0074] The driving element 134 can be a motor. The driving element 134 can drive the first gear 131 to rotate, drive the second gear 132 to rotate, or drive both gears simultaneously. It should be noted that when the driving assembly 130 simultaneously drives the first gear 131 and the second gear 132, the driving assembly 130 drives both gears to rotate in the same direction. In some embodiments, the driving element 134 drives the first gear 131 to rotate; for ease of description below, the following description uses the example of the driving element 134 driving the first gear 131 to rotate. The chain 133 is sleeved around the first gear 131 and the second gear 132. The chain 133, fitted around the first gear 131 and the second gear 132, is racetrack-shaped, with two straight segments (the first straight segment 1331 and the second straight segment 1332) and two arc segments. The two arc segments are located on the first gear 131 and the second gear 132, respectively, and the two straight segments are located between the first gear 131 and the second gear 132, with the straight segments arranged along a second direction. The first connecting assembly 122 and the second connecting assembly 123 are both connected to the straight segments of the chain 133. The drive element 134 rotates, causing the first gear 131 to rotate, which in turn causes the chain 133 to rotate, and the chain 133 causes the second gear 132 to rotate. The first connecting assembly 122 and the second connecting assembly 123 are both connected to the chain 133, and the rotation of the chain 133 causes the first connecting assembly 122 and the second connecting assembly 123 to move along the first direction.

[0075] In some embodiments, a hand crank 150 is provided on the second gear 131. Rotating the hand crank 150 can drive the second gear 131 to rotate, thereby driving the chain 133 to rotate, so as to facilitate manual control in case of damage to the drive element 134 or power supply.

[0076] In some embodiments, the chain 133 has a first straight segment 1331 and a second straight segment 1332. A first connecting component 122 is connected to one of the first straight segment 1331 and the second straight segment 1332, and a second connecting component 123 is connected to the other. The first straight segment 1331 and the second straight segment 1332 move in opposite directions. When the chain 133 rotates, the first connecting component 122 and the second connecting component 123 move towards each other or away from each other. This design allows the first connecting component 122 and the second connecting component 123 to move closer or further away synchronously, which helps to ensure that the first connecting component 122 and the second connecting component 123 are respectively located above the two edges of the strip 400, facilitating the use of the upper cold water guiding device 100.

[0077] In some embodiments, the support body 121 is provided with a guide portion 1211 extending in a second direction, and the first connecting assembly 122 includes a first roller 1221 and a first pull rod 1222. The first roller 1221 is located on the guide portion 1211 and is in rolling contact with the guide portion 1211. The first pull rod 1222 is located between the first roller 1221 and the first guide member 110, is fixedly connected to the first guide member 110, and is rotatably connected to the first roller 1221.

[0078] With this design, the first connecting component 122 rolls in contact with the support body 121 via the first roller 1221, which helps reduce the friction between the first connecting component 122 and the support body 121, ensuring smooth movement of the first connecting component 122.

[0085] The following is Figure 1The working principle of the upper cold water diversion device 100 is introduced by taking the structure shown as an example:

[0086] When the connecting mechanism 120 of the upper cold water guiding device 100 is connected to the upper cold water manifold 200, the gathering channel 110a is located below the two adjacent upper cold water manifolds 200 along the second direction; the two guiding channels 140a are respectively located below the two adjacent upper cold water manifolds 200 along the other side of the second direction; the guiding channel 110b is located below the interval area between the two adjacent upper cold water manifolds 200; and the receiving channel 140b is located below the first liquid outlet 110b1. The upper cold water from the two upper cold water manifolds 200 along the second direction will fall into the gathering channel 110a, enter the guiding channel 110b along the gathering channel 110a, and enter the receiving channel 140b along the guiding channel 110b, and finally be discharged to the outside of the strip through the third liquid outlet 140b1 of the receiving channel 140b. The upper chilled water from the two upper cooling manifolds 200 along the second direction will fall into the two guide channels 140a respectively, and finally be discharged to the outside of the strip from the second outlet 140a1 of the guide channel 140a. When the width of the processed strip changes, the output shaft of the control drive element 134 rotates clockwise or counterclockwise to make the first guide element 110 and the second guide element 140 move closer or further apart to adapt to the change in strip width. When the drive element 134 is damaged or energized, the hand crank 150 can be manually turned to drive the second gear 131 to rotate, thereby driving the chain 133 to rotate, making the first guide element 110 and the second guide element 140 move closer or further apart to adapt to the change in strip width.

[0087] Based on the same inventive concept, this application also provides a strip cold zone system, including a roller conveyor 300, a layer cooling upper manifold 200, and the aforementioned upper cooling water guiding device 100. The roller conveyor 300 is used to transport strip steel 400; the layer cooling upper manifold 200 is disposed above the roller conveyor 300; the connecting mechanism 120 of the upper cooling water guiding device 100 is connected to the layer cooling upper manifold 200.

[0088] It should be noted that, as Figure 2 As shown, multiple cooling manifolds 200 are typically spaced apart above the roller conveyor 300 along its length, and the cooling manifolds 200 extend along the width of the roller conveyor 300. A connecting mechanism 120 is fixedly connected to the cooling manifolds 200. After the fixed connection, a first direction is parallel to the length of the roller conveyor 300, and a second direction is parallel to the width of the roller conveyor 300. The flow-gathering groove 110a is simultaneously located below one side of the multiple cooling manifolds 200 along the second direction.

[0089] Since the strip cooling system includes the aforementioned upper cold water guiding device 100, it naturally possesses all the beneficial effects of the upper cold water guiding device 100, which will not be elaborated here.
