[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The core of this application is to provide a chassis cover and chassis for a CDU system, which allows operators to easily pull the chassis forward.

[0044] A specific embodiment of the CDU system chassis cover provided in this application is shown in Figures 1 to 6. It includes a cover body 1, which, when actually applied to a chassis, is located at the front end of the chassis. The cover body 1 has a first end face 14 and a second end face 15 at its two ends in the first direction X. A handle through hole 11 is formed in the cover body 1 along the first direction X. In practical applications, the first direction X corresponds to the front-rear direction. The first end face 14 is the front surface of the cover body 1, and the second end face 15 is the back surface of the cover body 1. For ease of description, the front surface of the cover body 1 in the following text refers to the first end face 14, and the back surface of the cover body 1 refers to the second end face 15.

[0045] A handle through hole 11 is formed on the cover plate body 1 along the first direction X, that is, the handle through hole 11 extends along the first direction X, and the two ends are respectively on the front surface and the back surface of the cover plate body 1. Depending on the actual space, it can be set as a rectangle, or it can be set as a circle, square or other shapes.

[0046] The cover body 1 is movably connected to the handle 2, for example, by a rotatable connection or a sliding connection. The handle 2 can move through the handle through hole 11 to extend or retract relative to the first end face 14. Specifically, extending the handle 2 relative to the first end face 14 means extending it beyond the first end face 14 in the first direction X; retracting the handle 2 relative to the first end face 14 means that it no longer protrudes beyond the first end face 14 in the first direction X. When it is necessary to pull the case forward, the handle 2 is extended forward through the handle through hole 11 before the first end face 14, and the case is pulled using the handle 2. When it is not necessary to pull the case forward, the handle 2 is retracted back to its original position.

[0047] A tray 3 is provided on the back of the cover body 1. The tray 3 is positioned below the handle 2 to block the handle 2 from below.

[0048] On this type of chassis cover, a movable handle 2 is provided to offer a point of leverage for the operator. During use, the first end face 14 can be used as the front surface of the chassis, allowing the operator to directly pull the handle 2, which extends from the front surface of the cover body 1, to pull the chassis out. Simultaneously, the handle 2 can retract to a position where it does not protrude forward from the front surface of the cover body 1, thus maintaining the flatness of the front surface. Furthermore, since a tray 3 is provided on the back of the cover body 1, any liquids or impurities brought into the chassis by the handle 2 can fall onto the tray 3, providing a protective effect and ensuring safety during use.

[0049] As shown in Figures 4 to 6, the handle 2 is rotatably connected to the cover body 1, making it easy to operate. Specifically, the handle 2 includes a first plate 21 and a second plate 22 connected to the first plate 21. The middle part of the first plate 21 is rotatably connected to the handle through hole 11 via a rotating shaft 23. When the first plate 21 rotates around the rotating shaft 23, it can drive the second plate 22 to rotate through the handle through hole 11, so that the first plate 21 and the second plate 22 extend or retract relative to the first end face 14, ensuring the area on the handle 2 available for workers to contact.

[0050] The rotating shaft 23 extends along the vertical direction Z and is connected to the middle of the handle through hole 11 in the second direction Y. Alternatively, the rotating shaft 23 can also be connected to the edge of the handle through hole 11. In other embodiments, the rotating shaft 23 can also be installed at other angles. For example, the rotating shaft 23 extends along the second direction Y. Specifically, the rotating shaft 23 and the handle 2 in this embodiment can be rotated at a certain angle and installed on the cover plate body 1.

[0051] It should be noted that in this embodiment, the first direction X, the second direction Y, and the up-down direction Z are three different directions, which are perpendicular to each other. In this case, the second direction Y corresponds to the left-right direction in the orientation shown in Figure 1. Of course, in other embodiments, the first direction X, the second direction Y, and the up-down direction Z can also be set at other angles.

[0052] In this design, the first plate 21 and the second plate 22 are connected to form a ring structure. Specifically, the two ends of the second plate 22 are respectively connected to the two ends of the first plate 21, or one or both ends of the second plate 22 are connected to the middle of the first plate 21. Furthermore, the first plate 21 is a flat plate, and the second plate 22 is an arc-shaped plate or a folded plate. In addition to the ring structure, the handle 2 can also be a hook structure, etc.

[0053] In the second direction Y, the handle 2 can be rotated out from both sides of the pivot 23; or, it can only be rotated out from one side, while the other side is limited by the cover body 1 and cannot be rotated out.

[0054] In order to prevent the handle 2 from moving freely when not in use, the handle 2 and the pivot 23 can also be damped; or, an elastic element can be provided between the handle 2 and the pivot 23, so that the handle 2 will automatically retract with the restoring force of the elastic element after it is no longer subjected to external force.

[0055] Alternatively, in other embodiments, the handle 2 can also be slidably connected to the handle through hole 11. In this case, a groove can be provided on the handle 2 to allow a finger to be inserted to pull the handle 2 out of the handle through hole 11, or a rebound device can be provided on the handle 2 so that the handle 2 can be pushed out of the handle through hole 11 by pressing the handle 2. In addition, a limit can be formed between the handle 2 and the cover plate body 1 to limit the maximum distance the handle 2 can move forward and prevent the handle 2 from disengaging from the cover plate body 1.

[0056] As shown in Figure 1, after the handle 2 retracts to the front surface of the cover body 1 and does not protrude forward, the handle through hole 11 can be sealed to prevent liquids, impurities, etc. from entering the chassis through the handle through hole 11 when the handle 2 is not in use.

[0057] To ensure a good seal, the handle 2 and the handle through hole 11 can be made to be the same size, and the seal is achieved by fitting the handle 2 and the handle through hole 11 together; or, a sealing ring can be provided on the handle 2 or the handle through hole 11 to ensure a good seal. In this case, the sealing ring can also provide a certain amount of damping to prevent the handle 2 from extending out accidentally.

[0058] As shown in Figure 1, the two handles 2 are located at both ends of the cover body 1 along the second direction Y, providing different points of force application and allowing for a smoother pulling of the case. Of course, in other embodiments, the number of handles 2 can also be different, such as one or three.

[0059] As shown in Figure 1, the handle 2 is located at the top of the cover body 1. The chassis is formed by the cover body 1 and the rear main housing 8. Since the equipment inside the chassis may need to be placed on the bottom of the chassis for support, placing the handle 2 at the top can avoid interference with other equipment inside the chassis. Of course, in other embodiments, when space permits, the handle 2 and the tray 3 can also be located in the middle or below the cover body 1.

[0060] The top of the tray 3 also has a tray cover to cover the handle 2, preferably sealing the top opening of the tray 3, forming a single-opening chamber with only the handle through hole 1, achieving complete isolation from the inside of the chassis, further preventing liquid from entering the chassis and improving electrical isolation. Of course, in other embodiments, the tray cover may also partially cover the top opening of the tray 3.

[0061] The tray 3 can be fixed to the cover body 1 by welding, bolting, or other methods. In addition, the tray 3 can be made of metal or insulating material.

[0062] The tray 3 includes a base plate and a first side plate 32 disposed above the edge of the base plate 31. During installation, it is necessary to ensure that the base plate 31 is directly below the handle 2 and the first side plate 32 is located outside the projection of the handle 2 onto the base plate 31 in the vertical direction, so as to ensure the load-bearing capacity of the tray 3.

[0063] To ensure the normal movement of the handle 2, there is a certain gap between the base plate 31, the first side plate 32 and the handle 2.

[0064] The first side plate 32 can be completely offset from the handle 2 in the vertical direction, that is, the bottom of the handle 2 is higher than the first side plate 32, or it can be partially offset, or the top of the first side plate 32 is not lower than the top of the handle 2, so as to achieve full lateral coverage of the handle 2.

[0065] The shape of the base plate 31 can be adapted to the handle 2, such as a rectangle, a semicircle, etc.

[0066] The tray cover can be integrally formed or fixed to the tray 3 by means of bolt connection, or the tray cover can be movably connected to the cover body 1 or the tray 3 to realize the opening and closing of the top of the tray 3, which facilitates the maintenance of the handle.

[0067] As shown in Figures 5 and 6, an electrical control box 4 is also provided on the back of the cover body 1. The electrical control box 4 contains electrical control components, specifically including a display module 9, whose front end is located on the middle through hole of the cover body 1 and whose rear end extends into the electrical control box 4. The electrical control box 4 has a top opening 41, which can be covered by the tray cover of the top plate 81 of the main chassis 8.

[0068] Specifically, the tray 3 and the handle 2 are located at the top opening 41, which avoids occupying the main space of the electrical control box 4.

[0069] Specifically, a first through hole 12 for installing a fluid connector 5 is provided on the cover body 1. The first through hole 12 is located on one side of the electrical control box 4 in the second direction Y. A baffle plate 7 is also fixedly provided on the back of the cover body 1 above the first through hole 12 to block the liquid between the top of the first through hole 12 and the top opening 41, so as to prevent the liquid from splashing upward into the electrical control box 4 in the event of an accidental liquid splash at the fluid connector 5.

[0070] Multiple first through holes 12 are provided in the vertical direction Z, which can be used for liquid replenishment or drainage. In cases of limited space, only one baffle 7 can be provided above the topmost first through hole 12. One end of the baffle 7 in the second direction Y can extend to the electrical control box 4 to ensure waterproofing, and the other end can extend to the inner wall of the main housing 8, which can be bolted to the main housing 8.

[0071] The water baffle 7 can be in the shape of a flat plate, an L-shaped plate, a U-shaped plate with an upward convexity, or an arc-shaped plate with an upward convexity.

[0072] Specifically, the cover plate body 1 also has a second through hole 13 for installing an electrical connector 6. The electrical connector 6 includes a connection structure for connecting electrical appliances, wires, and network cables. The second through hole 13 is located at the front of the electrical control box 4 and connects to the electrical control box 4. A mounting plate 10 is provided on the back of the cover plate body 1, around the second through hole 13, for installing a temperature and humidity sensor. At this time, the temperature and humidity sensor is located in the electrical control box 4, which can monitor the temperature and humidity inside the electrical control box 4 in a timely manner.

[0073] Multiple second through holes 13 can be provided in the vertical direction Z. In the second direction Y, the first through holes 12 and the second through holes 13 can be distributed at both ends of the cover plate body 1. A mounting plate 10 can be provided below the second through hole 13 and on the side of the second through hole 13 in the second direction Y that is close to the first through hole 12.

[0074] In addition to the aforementioned chassis cover, this application also provides a chassis for a CDU system, which includes a chassis cover. The chassis cover can specifically be the chassis cover provided in any of the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly.

[0075] The chassis also includes a main housing 8 fixed to the rear side of the cover body 1. The main housing 8 has a top cover 811, which covers the top opening of the tray 3 and covers the handle 2. At this time, the top cover 811 and the tray 3 form a cavity with only one opening, the handle through hole 11, which has a better electrical isolation effect and completely isolates the handle 2 from the space inside the chassis.

[0076] Specifically, the tray 3 includes a bottom plate and a first side plate 32 disposed above the edge of the bottom plate 31, and the top cover 811 includes a top plate and a second side plate 812 disposed below the edge of the top plate. The top surface of the first side plate 32 and the bottom surface of the second side plate 812 are fastened together to achieve a seal.

[0077] Specifically, the tray 3 and handle 2 are located on the top of the main body 8. At this time, the top cover 811 can be integrally formed on the top plate 81 of the body 8. In addition, the tray cover on the top of the tray 3 mentioned in the above embodiment and the top cover 811 in this embodiment can be the same structure, or they can be set at the same time and separately, or one of them can be set.
