The mechanism comprises a baffle, a bearing piece and an elastic piece. The baffle is arranged on the bearing part in a sliding manner; the first end of the elastic piece is connected to the bearing piece, and the second end of the elastic piece abuts against the baffle. The target piece is located on the side, opposite to the elastic piece, of the baffle. The elastic piece is configured to make the baffle close to and contact with the target piece based on elastic deformation of the elastic piece; wherein under the condition that the baffle makes contact with the target piece, the baffle shields the side face, facing the baffle, of the target piece. According to the shielding mechanism, the target piece is shielded through the baffle in the shielding mechanism, and on the basis of the elastic piece arranged on the baffle and the slidable connection between the baffle and the bearing piece in the shielding mechanism, the target piece can be shielded by keeping the minimum gap between the baffle and the bearing piece on the basis of the elasticity of the elastic piece under the condition that the target piece stretches out, draws back and expands. Therefore, the protection effect on the target piece is improved.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical structures, in particular to a shielding mechanism and a cooling system. BACKGROUND

[0002] The shielding mechanism is generally used to shield the target piece to protect the target piece. For example, the temperature change of some target pieces is more obvious, and the working performance of these target pieces is greatly affected by thermal expansion and contraction. Therefore, shielding the target piece by the shielding mechanism can isolate the target piece from the external environment to some extent, thereby reducing the influence of temperature change of the external environment on the target piece.

[0003] It can be seen that in the way of shielding the target piece by the shielding mechanism to isolate the external environment to some extent, the main factor affecting the protection effect is the gap size between the target piece and the shielding mechanism (specifically the shielding plate in the shielding mechanism) when the target piece is shielded. However, there is currently no shielding mechanism that can shield the target piece with a smaller gap to better protect the target piece.

[0004] That is, the current shielding mechanism is not good enough to protect the target piece. SUMMARY

[0005] The purpose of the present application is to provide a shielding mechanism and a cooling system, which shields the target piece by the shielding plate in the shielding mechanism, and based on the elastic piece arranged on the shielding plate and the slidable connection between the shielding plate and the bearing piece in the shielding mechanism, the shielding plate can shield the target piece with the smallest gap based on the elasticity of the elastic piece when the target piece expands and contracts. Thus, the protection effect on the target piece can be improved.

[0006] In a first aspect, the present application provides a shielding mechanism for shielding a target piece; the mechanism includes a shielding plate, a bearing piece, and an elastic piece; the shielding plate is slidably arranged on the bearing piece; the first end of the elastic piece is connected to the bearing piece, and the second end of the elastic piece abuts the shielding plate; wherein the target piece is located on the side of the shielding plate away from the elastic piece; the elastic piece is configured to make the shielding plate close to and contact the target piece based on its elastic deformation; wherein in the case that the shielding plate contacts the target piece, the shielding plate shields the side of the target piece facing the shielding plate.

[0007] The shielding mechanism contacts the target member by the baffle and shields the target member, and based on the elasticity of the elastic member and the slidable connection between the baffle and the carrier, the baffle can always shield the target member with the smallest gap based on the elasticity of the elastic member when the target member expands or contracts, thereby better isolating the external environment of the target member and improving the protection effect of the target member.

[0008] With reference to the first aspect, optionally, the mechanism further comprises a guide column; the elastic member comprises a spring; a first end of the guide column is connected with the carrier, and a second end of the guide column faces the baffle; and the spring is sleeved on the guide column.

[0009] The shielding mechanism sleeves the spring on the guide column, so that the expansion and contraction of the spring is constrained in the length direction of the guide column, that is, the elastic force of the spring is constrained in the length direction of the guide column. To a great extent, the spring is prevented from expanding and contracting in other directions, thereby maximizing the elasticity of the spring, and ultimately further ensuring that the baffle always maintains a state of contacting the target member, and further improving the protection effect of the target member.

[0010] With reference to the first aspect, optionally, the carrier is provided with a connecting portion; the connecting portion extends outward from a first position of the carrier; the first position is located on a surface of the carrier carrying the baffle, on a side of the baffle facing away from the target member; and a first end of the guide column is connected with the connecting portion.

[0011] The shielding mechanism provides the connecting portion on the carrier for connecting with the spring, so that the expansion direction of the spring can be substantially parallel to the movable direction of the baffle, and the process of opening a receiving groove on the carrier for accommodating the spring is omitted, and based on the connecting portion extending outward from the carrier, the spring can be arranged more outwardly relative to the carrier, so that the space around the spring is more sufficient, thereby being applicable to more types of elastic members.

[0012] With reference to the first aspect, optionally, the carrier comprises a carrier plate, a bottom plate and a connecting plate; the baffle is arranged on the carrier plate; the carrier plate and the connecting plate are arranged opposite to each other; the connecting plate is located between the carrier plate and the bottom plate; a first edge of the connecting plate is connected with a middle portion of the carrier plate, and a second edge of the connecting plate is connected with a middle portion of the bottom plate; and the first edge and the second edge are arranged opposite to each other.

[0013] The aforementioned shielding mechanism, through the connection between the support plate, base plate, and connecting plate, allows the cross-section of the support component to have an "I"-like structure, thereby improving its bending resistance. By improving the bending resistance of the support component, the smooth sliding of the baffle is virtually eliminated due to bending of the support component. Ultimately, this ensures highly efficient protection of the target component.

[0014] In conjunction with the first aspect, the mechanism may optionally further include a sleeve; the sleeve is fitted onto the guide post; a first end of the sleeve is connected to the baffle, and a second end of the sleeve is connected to the second end of the spring.

[0015] The aforementioned shielding mechanism, by incorporating a sleeve on the baffle and connecting the baffle to the spring via the sleeve, redirects the stress generated by the spring onto the sleeve, reducing the risk of damage to the baffle caused by direct stress acting on it. Furthermore, by transmitting the spring force to the baffle through the sleeve, the maximum stroke of the spring is limited, thereby reducing the risk of spring failure due to overload. Ultimately, this further ensures that the baffle can move smoothly under the action of the spring to maintain contact with the target component, thus ensuring effective protection of the target component.

[0016] In conjunction with the first aspect, optionally, the baffle includes a blocking portion and a padding portion; the blocking portion is configured to block the side of the target member facing the baffle; the padding portion is attached to the side of the blocking portion facing the elastic member; and the first end of the sleeve is connected to the padding portion.

[0017] The aforementioned shielding mechanism, by providing a padding portion to the baffle, with the padding portion bearing the force transmitted by the spring through the sleeve, and when the padding portion applies this force to the shielding portion, the pressure corresponding to the force on the shielding portion is smaller due to the relatively large area of ​​the shielding portion, thus further protecting the baffle. Ultimately, this further ensures the effectiveness of protecting the target component.

[0018] In conjunction with the first aspect, optionally, the baffle further includes a sliding portion; the sliding portion is connected to the edge of the blocking portion near the carrier and is slidably connected to the carrier; wherein the surface friction coefficient of the sliding portion toward the carrier is less than the surface friction coefficient of the blocking portion toward the carrier.

[0019] The aforementioned shielding mechanism improves the smoothness of the baffle sliding on the support by equipping the baffle with a sliding part with a lower coefficient of friction, thereby further ensuring the protective effect of the baffle on the target component by maintaining contact with it.

[0020] In conjunction with the first aspect, optionally, the blocking portion is connected to the edge of the sliding portion; the sliding portion is located on the side of the blocking portion facing away from the target member.

[0021] The aforementioned shielding mechanism, through its structural design where the sliding part is located on the side of the shielding part facing away from the target part, avoids the sliding part occupying the space between the shielding part and the target part, thereby avoiding the impact on the travel of the baffle sliding on the support member. This further ensures the protective effect of the baffle on the target part by maintaining contact with it.

[0022] Secondly, this application provides a cooling system including a crossbar, a cooling tube bundle, and a shielding mechanism described in the first aspect; the cooling tube bundle includes a plurality of cooling tubes arranged along a first direction; wherein the first direction intersects the plane where the shielding portion of the shielding mechanism is located; the length direction of the cooling tubes is parallel to the plane where the shielding portion is located; the crossbar is connected to the end of the support member; one end of the cooling tube is hung on the crossbar; the elastic element of the shielding mechanism is configured to, based on its elastic deformation, bring the baffle close to and contact the cooling tube bundle; wherein, when the baffle contacts the cooling tube bundle, the baffle shields the side of the cooling tube bundle facing the baffle.

[0023] The cooling system described above has the same beneficial effects as the first aspect or any alternative implementation thereof, which will not be repeated here.

[0024] In summary, the shielding mechanism and cooling system provided in this application, through the elasticity of the elastic element and the slidable connection between the baffle and the carrier, can ensure that the baffle maintains a minimum gap to shield the target component even when it expands or contracts, thereby better isolating the target component from the external environment and improving its protection. By sleeved on the guide post, the elasticity of the spring is maximized, further ensuring that the baffle remains in contact with the target component, further enhancing its protection. The connection between the carrier plate, base plate, and connecting plate allows the carrier component to have an "I"-shaped cross-section, improving its bending resistance. By providing a sleeve on the baffle and connecting it to the spring through the sleeve, the maximum stroke of the spring is limited, reducing the risk of spring failure due to overload. By providing a padding portion to the baffle, which bears the force transmitted by the spring through the sleeve, the baffle is further protected. By equipping the baffle with a sliding part that has a lower coefficient of friction, the smoothness of the baffle sliding on the load-bearing component is improved, thereby further ensuring the protective effect of the baffle on the target component by maintaining contact with it.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0034] It should be noted that similar reference numerals and letters refer to similar items throughout the accompanying drawings, and once an item is defined in one drawing, it is not necessary to further define and explain it in subsequent drawings.

[0035] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed during use, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] In addition, the terms "horizontal", "vertical" and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0037] In the description of the present application, it should also be noted that unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between the two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] Taking the cooling tube bundle in the air cooling island as an example, in the process of changing the environment temperature with or without steam in the tube, the tube bundle will appear thermal expansion and contraction. Thermal expansion and contraction can easily cause the tube bundle to expand and crack, thereby reducing the heat exchange capacity of the air cooling island. Therefore, it is necessary to avoid the damage of thermal expansion and contraction to the tube bundle to ensure the heat exchange capacity of the air cooling island.

[0039] Further, to achieve the above-mentioned purpose, the baffle can be used to shield the tube bundle to reduce the influence of the environment temperature on the tube bundle to a certain extent. However, if the baffle is fixedly installed on the edge or frame of the tube bundle, since the tube bundle will still have the phenomenon of thermal expansion and contraction, the gap between the baffle and the tube bundle will become larger, or the fixed connection between the baffle and the frame will be damaged due to the expansion of the tube bundle, thereby affecting the effect of the baffle on the external environment temperature isolation of the tube bundle. Ultimately, the protection of the tube bundle is reduced, and the heat exchange performance of the air cooling island is affected.

[0040] Therefore, the application provides a shielding mechanism and a cooling system to solve the above technical problems. Specifically, please refer to the embodiments and drawings provided by the application.

[0041] Please refer to Figure 1 , Figure 1 is a first perspective view of the shielding mechanism 100 provided by the embodiments of the application. The shielding mechanism 100 provided by the embodiments of the application can be used to shield the target piece 20. The shielding mechanism 100 can include a baffle 110, a carrier 120, and an elastic piece 130. The baffle 110 can be slidably arranged on the carrier 120. The first end of the elastic piece 130 can be connected to the carrier 120, and the second end of the elastic piece 130 can abut against the baffle 110. The target piece 20 can be located on the side of the baffle 110 away from the elastic piece 130. The elastic piece 130 can be configured to cause the baffle 110 to approach and contact the target piece 20 based on the elastic deformation thereof. When the baffle 110 contacts the target piece 20, the baffle 110 can shield the side of the target piece 20 facing the baffle 110.

[0042] The target piece 20 can be a component with a large thermal expansion and contraction performance, such as a cooling tube bundle 300 in an air cooling island or a heat collecting pipe on a solar water heater.

[0043] The baffle 110 can have a shielding surface, which can be directed towards the target piece 20 and substantially parallel to one of the expansion and contraction directions of the target piece 20, or substantially parallel to the direction in which the target piece 20 expands most obviously. The slidable connection between the baffle 110 and the carrier 120 can be that the baffle 110 is directly movably arranged on the carrier surface of the carrier 120, or that the carrier 120 is provided with a sliding groove or sliding rail matched with the baffle 110, and the baffle 110 is slidable connected with the carrier 120 through the sliding groove or sliding rail. The initial state of the baffle 110 just installed on the carrier 120 can be that the baffle 110 is in contact with the target piece 20 in the state that the target piece 20 has the largest size based on the thermal expansion and contraction effect. The elastic member 130 can be a spring, a metal spring, a bellows, etc. The second end of the elastic member 130 can only be in contact with the baffle 110, or can be connected together, for example, welded, clamped, etc. When the baffle 110 is in contact with the target piece 20 and the target piece 20 is in the state of the largest size, the elastic member 130 can be in a compressed state. During the contraction of the target piece 20 based on the thermal expansion and contraction effect, the elastic member 130 can recover to the initial state based on the compression state and elasticity of the elastic member 130. Accordingly, by pushing the baffle 110 to make the baffle 110 close to the target piece 20 and always keep in contact with the target piece 20, the shielding of the target piece 20 is realized. Conversely, during the expansion of the target piece 20, the target piece 20 pushes the baffle 110 to move towards the elastic member 130, and due to the elasticity of the elastic member 130, the movement trend of the baffle 110 can be released by the compression of the elastic member 130.

[0044] During the above implementation process, by contacting the target piece 20 with the baffle 110 and shielding the target piece 20, and based on the elasticity of the elastic member 130 and the slidable connection between the baffle 110 and the carrier 120, the baffle 110 can always shield the target piece 20 with the smallest gap based on the elasticity of the elastic member 130 when the target piece 20 expands and contracts, so that the external environment of the target piece 20 is better isolated, and the protection effect of the target piece 20 is improved.

[0045] Please refer to Figure 2 , Figure 2 is Figure 1 the enlarged view of part A in FIG. 1. In some optional embodiments, the mechanism provided by the embodiments of the present application can further include a guide column 140. The elastic member 130 can include a spring. The first end of the guide column 140 can be connected with the carrier 120, and the second end of the guide column 140 can be directed towards the baffle 110. The spring can be sleeved on the guide column 140.

[0046] In combination with the foregoing description, the length direction of the guide column 140 can be substantially parallel to the orientation of the shielding surface of the baffle 110. The guide column 140 can be cylindrical or other prism-shaped, such as a quadrangular prism, a hexagonal prism, etc.

[0047] In the above implementation process, by sleeving the spring on the guide column 140, the expansion and contraction of the spring is constrained in the length direction of the guide column 140, that is, the elastic force of the spring is constrained in the length direction of the guide column 140. To a great extent, the spring is prevented from expanding and contracting in other directions, thereby maximizing the use of the elasticity of the spring, and ultimately further ensuring that the baffle 110 always maintains a state of contacting the target piece 20, thereby further improving the protection effect on the target piece 20.

[0048] Please refer to Figure 3 , Figure 3 is a second perspective view of the shielding mechanism 100 provided by the embodiments of the present application. In some optional embodiments, the carrier 120 can be provided with a connecting portion 121. The connecting portion 121 can extend outwardly from a first position of the carrier 120. The first position can be located on the surface of the carrier 120 carrying the baffle 110, on the side of the baffle 110 facing away from the target piece 20. The first end of the guide column 140 can be connected with the connecting portion 121.

[0049] In combination with the foregoing description of the shielding surface of the baffle 110, that is, the orientation of the shielding surface is away from the first position and the connecting portion 121. The first end of the guide column 140 can be connected with the carrier 120 through the connecting portion 121.

[0050] In the above implementation process, by providing the connecting portion 121 for connecting with the spring on the carrier 120, the process of opening a receiving groove for accommodating the spring on the carrier 120 is omitted while ensuring that the expansion and contraction direction of the spring is substantially parallel to the movable direction of the baffle 110. Based on the connecting portion 121 extending outwardly from the carrier 120, the setting position of the spring can be more outward relative to the carrier 120, so that the space around the spring is more sufficient, thereby being applicable to more types of elastic members 130.

[0051] Please continue to refer to Figure 3 In some optional embodiments, the carrier 120 can include a carrier plate 122, a bottom plate 123, and a connecting plate 124. The baffle 110 can be arranged on the carrier plate 122. The carrier plate 122 and the connecting plate 124 can be oppositely arranged. The connecting plate 124 can be located between the carrier plate 122 and the bottom plate 123. The first edge of the connecting plate 124 can be connected with the middle portion of the carrier plate 122, and the second edge of the connecting plate 124 can be connected with the middle portion of the bottom plate 123. The first edge can be oppositely arranged with the second edge.

[0052] In other words, the cross-section of the bearing member 120 can be I-shaped. The connection between the bearing plate 122, the base plate 123, and the connecting plate 124 can be welded or integrally formed.

[0053] In the above implementation process, by connecting the bearing plate 122, the base plate 123, and the connecting plate 124, the cross-section of the bearing member 120 can be shaped like an "I," thereby improving the bending resistance of the bearing member 120. Based on this improved bending resistance, the impact of bending of the bearing member 120 on the smooth sliding of the baffle 110 is almost completely avoided. Ultimately, this ensures efficient protection of the target component 20.

[0054] Please refer to this again. Figure 2 In some optional embodiments, the shielding mechanism 100 provided in this application may further include a sleeve. The sleeve may be fitted onto the guide post 140. The first end of the sleeve may be connected to the baffle 110, and the second end of the sleeve may be connected to the second end of the spring.

[0055] The aforementioned sleeve and guide post 140 can be manufactured separately, with the sleeve 150 placed on top of the guide post 140, or they can be integrally formed, having annular steps of varying thicknesses. Specifically, the second end of the spring can be connected to the end face of the sleeve facing the connecting portion 121. Alternatively, if the sleeve and guide post are integrally formed, the second end of the spring can be connected to the annular step.

[0056] In the above implementation process, by setting a sleeve on the baffle 110 and connecting the baffle 110 to the spring through the sleeve, the stress generated by the spring is transferred to the sleeve, reducing the risk of damage to the baffle 110 caused by the stress acting directly on it. Furthermore, by transmitting the spring force to the baffle 110 through the sleeve, the maximum stroke of the spring is limited, thereby reducing the risk of spring failure due to overload. Finally, this further ensures that the baffle 110 can move smoothly under the action of the spring to maintain contact with the target component 20, thus ensuring the effective protection of the target component 20.

[0057] Please refer to Figure 4 , Figure 4 This is a perspective view of the baffle 110 in the shielding mechanism 100 provided in this application embodiment. In some optional embodiments, the baffle 110 may include a shielding portion 111 and a padding portion 112. The shielding portion 111 may be configured to shield the side of the target member 20 facing the baffle 110. The padding portion 112 may be attached to the side of the shielding portion 111 facing the elastic member 130. The first end of the sleeve may be connected to the padding portion 112.

[0058] The shielding part 111 can be a part of the baffle 110 directly shielding the target piece 20, and the gasket part 112 can be a part attached to the shielding part 111. The gasket part 112 can be square or circular in shape. The area size thereof can be slightly larger than the cross-sectional area of the sleeve. The thickness thereof can be substantially equal to the thickness of the shielding part 111, or can be thicker or thinner than the shielding part 111. The shielding part 111 and the gasket part 112 can be separately manufactured and assembled together by welding or screwing, or can be integrally formed. The sleeve is connected to the baffle 110 through the gasket part 112.

[0059] In the above implementation process, the gasket part 112 is configured for the baffle 110, and the gasket part 112 bears the force transmitted by the spring through the sleeve. When the gasket part 112 acts the force on the shielding part 111, the shielding part 111 has a relatively large area, so the pressure corresponding to the force acting on the shielding part 111 is smaller, thereby further protecting the baffle 110. The effect of protecting the target piece 20 is further ensured.

[0060] Please continue to refer to Figure 4 In some optional embodiments, the baffle 110 can further include a sliding part 113. The sliding part 113 can be connected to the edge of the shielding part 111 close to the carrier 120, and can be in sliding connection with the carrier 120.

[0061] The surface of the sliding part 113 facing the carrier 120 has a smaller friction coefficient than the surface of the shielding part 111 facing the carrier 120. For example, the sliding part 113 can be a plate shape and fit the surface of the carrier 120 facing the baffle 110.

[0062] In the above implementation process, the baffle 110 is configured with the sliding part 113 having a smaller friction coefficient, which improves the smoothness of the sliding of the baffle 110 on the carrier 120, thereby further ensuring the protection effect of the baffle 110 on the target piece 20 by maintaining contact with the target piece 20.

[0063] Please continue to refer to Figure 4 In some optional embodiments, the shielding part 111 can be connected to the edge of the sliding part 113. The sliding part 113 can be located on the side of the shielding part 111 away from the target piece 20.

[0064] On the basis of the foregoing example, the cross-sectional shape of the combination of the sliding part 113 and the shielding part 111 can be in the shape of an "L".

[0065] In the implementation process, the sliding portion 113 is arranged on the side of the shielding portion 111 away from the target piece 20, which avoids the occupation of the space between the shielding portion 111 and the target piece 20 by the sliding portion 113, avoids the influence on the stroke of the baffle 110 sliding on the bearing piece 120, and further ensures the protection effect of the baffle 110 on the target piece 20 by keeping contact with the target piece 20.

[0066] Please refer to Figure 5 , Figure 5 is a partial structure perspective view of the cooling system 10 provided by the embodiment of the present application. Based on the same concept, the embodiment of the present application provides a cooling system 10, which can include a crossbar 200, a cooling tube bundle 300, and the shielding mechanism 100 described above. The cooling tube bundle 300 can include a plurality of cooling tubes arranged along a first direction. The first direction can intersect the plane where the shielding portion 111 of the shielding mechanism 100 is located. The length direction of the cooling tubes can be parallel to the plane where the shielding portion 111 is located. The crossbar 200 can be connected to the end of the bearing piece 120. One end of the cooling tube can be hung on the crossbar 200. The elastic member 130 of the shielding mechanism 100 can be configured to make the baffle 110 close to and contact the cooling tube bundle 300 based on the elastic deformation thereof. In the case where the baffle 110 contacts the cooling tube bundle 300, the baffle 110 can shield the side of the cooling tube bundle 300 facing the baffle 110.

[0067] The cooling system 10 described above can be the air cooling island mentioned above. Among the plurality of cooling tubes, a part can be used as a parallel flow tube bundle, and another part can be used as a counter flow tube bundle. The first direction can be approximately perpendicular to the plane where the shielding portion 111 is located, in other words, the first direction can be approximately parallel to the movable direction of the baffle 110.

[0068] One end of the cooling tube is hung on the crossbar 200, and the other end can be in a free state. In this case, both ends of the cooling tube are in a free state in the arrangement direction thereof, so that the thickness of the cooling tube will change accordingly in the case where the cooling tube is subjected to thermal expansion and contraction. Accordingly, the size of the cooling tube bundle 300 in the arrangement direction will change. In addition, the arrangement direction is approximately parallel to the movable direction of the baffle 110, so that the baffle 110 will keep contact with the cooling tube closest to the baffle 110 based on the elasticity of the elastic member 130 when the size of the cooling tube bundle 300 in the arrangement direction changes due to thermal expansion and contraction.

[0069] The implementation process described above can be the same as the shielding mechanism 100 described above, which will not be described herein again.

[0070] In summary, the shielding mechanism 100 and cooling system 10 provided in the various embodiments of this application, through the elasticity of the elastic member 130 and the slidable connection between the baffle 110 and the support member 120, can ensure that the baffle 110 always maintains a minimum gap to shield the target member 20 when the target member 20 expands or contracts, thereby better isolating the target member 20 from the external environment and improving the protection effect of the target member 20. By sleeved the spring on the guide post 140, the elasticity of the spring is utilized to the maximum extent, further ensuring that the baffle 110 always maintains contact with the target member 20, further improving the protection effect of the target member 20. Through the connection between the support plate 122, the base plate 123 and the connecting plate 124, the cross-section of the support member 120 can be in the shape of an "I" shape, thereby improving the bending resistance of the support member 120. By providing a sleeve on the baffle 110 and connecting the baffle 110 to the spring through the sleeve, the maximum stroke of the spring is limited, thereby reducing the risk of spring failure due to overload. By providing a pad 112 to the baffle 110, and having the pad 112 bear the force transmitted by the spring through the sleeve, the baffle 110 is further protected. By providing a sliding part 113 with a lower coefficient of friction to the baffle 110, the smoothness of the baffle 110 sliding on the bearing member 120 is improved, thereby further ensuring the protective effect of the baffle 110 on the target member 20 by maintaining contact with it.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
