All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

As shown in fig. 1 and 2, the embodiment of the present application provides a top-mounted water chiller, which is installed on an indoor roof in a hanging manner, that is, the roof is an installation position of the top-mounted water chiller, and the top-mounted water chiller can be suitable for various places with cooling requirements, for example, can be installed at a power exchange station of a new energy automobile to cool a battery pack, or can be installed at a factory workshop to cool manufacturing equipment, etc. The top-mounted water chilling unit mainly comprises a shell and a liquid cooling component, wherein the liquid cooling component is used for realizing heat dissipation, the liquid cooling component is arranged in the shell, the shell is an appearance component of the whole top-mounted water chilling unit, the top-mounted water chilling unit not only plays a role in protection and attractiveness, but also is used for realizing top-mounted installation through connection of the shell and the roof, namely, the top-mounted water chilling unit is in a specific connection mode, for example, as shown in fig. 1 and 2, a hanging piece 11 with a through hole is arranged on the shell, after penetrating through the through hole, connecting pieces such as an expansion bolt and a hook are connected to a roof (or firstly connected to the roof and then hooked with the hanging piece 11) so as to realize installation, the shell comprises a top wall (not shown in the figure), a side wall and a bottom wall, and the hanging piece 11 is arranged on the top wall or on the side wall, and is close to the top wall, so that the top wall is close to and is not towards the roof, in a mounting state, for example, when the shell is in a cuboid shape, the side wall faces the wall, the bottom wall faces the bottom wall and faces the bottom wall and a window, so that the liquid cooling component can be normally cooled and a liquid cooling window can be formed, and a overhauling component can also be arranged on the side wall and a overhauling window or a overhauling window. In the concrete installation, since the top-mounted water chiller is suspended on the roof, a larger operation space is generally provided below the bottom wall of the housing, so that in most cases, an access window is provided on the bottom wall, or when the top-mounted water chiller is installed close to the wall, if the space between the side wall and the wall is smaller, the access window can be provided on the bottom wall or other side wall facing the wall, or when other components (such as a charging device for charging a battery pack) are provided on the ground below the bottom wall, the lower space is caused, and the access window can be provided on the side wall not adjacent to the wall.

On one hand, the top-mounted water chilling unit with the structure is characterized in that an overhaul window is formed in the side wall or the bottom wall which is not adjacent to the roof, so that maintainers can directly overhaul the liquid cooling assembly in a hanging state in an indoor space without dismantling the shell; on the other hand, the liquid cooling assembly is arranged around the overhaul window, so that maintenance personnel can smoothly touch the liquid cooling assembly to maintain the liquid cooling assembly when the maintenance personnel are in an indoor space outside the overhaul window. Therefore, an maintainer can directly utilize the indoor space and maintain the liquid cooling assembly in the shell through the overhaul window, the whole top-mounted water chilling unit is not required to be detached from the roof, additional disassembly and assembly operations are saved, the overhaul operation on the liquid cooling assembly is only required, the complexity of the whole maintenance operation is greatly reduced, the maintenance operation can be realized more simply and conveniently, and the maintenance process is time-saving and labor-saving. In addition, the liquid cooling components are distributed around the overhaul window, so that the liquid cooling components can be arranged more reasonably, the pipes are arranged more regularly and orderly, and the structural performance and the working performance of the top-mounted water chilling unit are improved while the overhaul operation is realized smoothly and conveniently.

In an alternative embodiment, as shown in fig. 1 and 2, the housing may include a first housing 1 and a second housing 2 that are tiled, and different components of the liquid cooling assembly are disposed in the first housing 1 and the second housing 2, respectively. By adopting the arrangement mode, on one hand, the liquid cooling assembly is divided into a plurality of shells such as the first shell 1, the second shell 2 and the like, the volume of each shell can be reduced, the problem that the sizes of the shells and the unit are overlong and difficult to process is solved, and the equivalent effect that the whole liquid cooling assembly is arranged in a larger shell is achieved by splicing the plurality of shells, so that the production and the installation of the top-mounted water chilling unit are facilitated; on the other hand, on the basis of setting up a plurality of casings, make these casings tiling set up (tiling set up refers to the projection of first casing 1 and second casing 2 on the roof does not have the coincidence portion, i.e. in the direction perpendicular to roof, first casing 1 and second casing 2 do not have the range upon range of parts) to can further make the diapire of first casing 1 and second casing 2 all be located on being on a parallel with the coplanar on roof, so just can reduce the top-mounted cooling water set and occupy too much indoor space in the vertical direction, that is, can make the top-mounted cooling water set up in the room higher, i.e. lateral dimension span increases, the height dimension reduces, thereby reserve bigger space for the below of top-mounted cooling water set in the room, make the room can install bigger equipment, make top-mounted cooling water set can be applicable to more places. In addition, a single housing having a large height dimension may be used to house the entire liquid cooling assembly without consideration of the above factors.

On the basis of a plurality of shells, the specific setting modes can be as follows: as shown in fig. 1 and 2, the liquid cooling assembly comprises a partial cooling circuit 5 for guiding a cooling liquid and a refrigerating circuit 6 for cooling the cooling liquid; the first shell 1 is provided with a first overhaul window 3, and a part of cooling circuit 5 is arranged in the first shell 1 and surrounds the first overhaul window 3; the second housing 2 is provided with a second access window 4, and at least part of components of the refrigeration circuit 6 are disposed in the second housing 2 (i.e., all components of the refrigeration circuit 6 may be disposed in the second housing 2, or a part of components may be disposed in the second housing 2, and another part of components may be disposed in the first housing 1, such as a second condenser 605 described later). As shown in fig. 1 and 2, the partial cooling circuit 5 refers to a part of the entire cooling circuit for cooling the battery pack, in which the components and the pipes for cooling the battery pack are disposed outside the top-mounted water chiller, that is, outside the first housing 1, while the rest of the cooling circuit (the rest is the partial cooling circuit 5, which includes components and connection relationships of the components will be described in the following description) is disposed in the first housing 1, and the refrigeration circuit 6 (the refrigeration circuit 6 may be understood as an air conditioning system) for cooling the cooling liquid is disposed in the second housing 2, so that different functional components of the liquid cooling assembly are disposed in different housings, so that mutual interference in the working process is avoided, and respective pipe layouts can be more reasonably optimized, so that the working performance and the structural performance are improved. In order to ensure that the two-part structure can be smoothly and conveniently maintained, the first shell 1 and the second shell 2 are provided with overhaul windows, and the partial cooling circuit 5 and the refrigeration circuit 6 are arranged around the overhaul windows on the respective shells, so that when entering the overhaul windows, an overhaul worker can conveniently contact each part by changing the facing direction, and all the parts can be inspected, maintained or replaced.

In an alternative embodiment, as shown in fig. 1 and 2, an electric control box for controlling the operation of the cooling circuit and the refrigerating circuit 6 is arranged in the second housing 2, and the electric control box and the refrigerating circuit 6 are arranged together around the second access window 4. The arrangement of the electric control box in the second housing 2 is made possible in that by optimizing the distribution of the components in the refrigeration circuit 6 in the second housing 2, a relatively large space can be reserved in the second housing 2, which space is able to accommodate the electric control box, whereas in the first housing 1, even if the distribution of the components of the partial cooling circuit 5 has been optimized, the remaining space in the first housing 1 is not sufficient to accommodate the electric control box, on the basis of which the electric control box is arranged in the second housing 2. Moreover, in order to ensure that the service personnel can maintain the electric control box through the second service window 4, the electric control box needs to be also arranged near the second service window 4, so that the electric control box and the refrigeration circuit 6 are commonly arranged around the second service window 4, specifically, the refrigeration circuit 6 may be arranged on one side or two adjacent sides of the second service window 4, while the electric control box is arranged on the other sides of the second service window 4, for example, the main component parts of the refrigeration circuit 6 (such main component parts refer to other components of the refrigeration circuit 6 except for a condenser described later) and the electric control box are respectively located on opposite sides of the second service window 4, such as the left side and the right side of the second service window 4. Therefore, the structural layout of the top-mounted water chilling unit can be further optimized.

As shown in fig. 1 and 2, the bottom wall of the second housing 2 includes a rotating portion that can rotate to the outside of the housing; the electronic control box comprises a first electronic control box 7 which is positioned at one side of the second access window 4 and is vertically arranged relative to the bottom wall of the second shell 2, and a second electronic control box 8 which is arranged on the rotating part and is parallel relative to the bottom wall of the second shell 2, wherein the second electronic control box 8 can rotate to the outside of the shell along with the rotating part. In the application, the electric control box with relatively large volume is split into two small-volume electric control boxes, namely a first electric control box 7 and a second electric control box 8, and the two electric control boxes can be used for respectively controlling different components, for example, the first electric control box 7 is used for controlling the refrigeration circuit 6 to work, and the second electric control box 8 is used for controlling part of the cooling circuit 5 to work and the like. When specifically setting up, the first automatically controlled box 7 of cuboid shape is fixed to be set up in one side of second access window 4, for example the right side, and make first automatically controlled box 7 set up perpendicularly for the diapire, and can laminate and connect on the right side wall of second casing 2, can make the overall arrangement of each part in the second casing 2 more reasonable like this, and the automatically controlled box 8 of cuboid shape then is on a parallel with the diapire setting, and fix on rotating portion, this rotating portion can be the part of diapire, it can rotate for other parts of diapire, the rotation mode can be the upset mode of edge pivoted around one side, also can be the autorotation mode of rotation around the central line, through the rotation of rotating portion, can shift second automatically controlled box 8 outside second casing 2 from second casing 2, thereby make the maintenance personnel's hand need not reentrant in second access window 4, the maintenance to second automatically controlled box 8 just can be realized in the outside of casing, the operating space is bigger, it is more convenient to operate. The preferred rotating part of the application transfers the second electric control box 8 to the outside of the second shell 2 by turning around one side edge, so that the second electric control box 8 can be switched to a vertical placing state by rotating 90 degrees from a horizontal placing state by means of self gravity, as shown in fig. 2, not only the height of the second electric control box 8 can be reduced, but also an operator can directly face the second electric control box 8, and further maintenance operation can be more conveniently and comfortably performed.

Preferably, the first access window 3 and the second access window 4 are both provided with an access door 9 for opening and closing the access windows, and the rotating part is rotatably connected with the access door 9 on the second access window 4. The access door 9 which can be opened and closed is arranged on the access window in a rotating mode, the access window can be blocked when the access is not needed, so that protection is formed on the liquid cooling component in the shell, the influence of the external environment on the work of the liquid cooling component is reduced, and when the liquid cooling component is required to be overhauled, an operator only needs to open the access door 9 to expose the liquid cooling component, and maintenance operation can be normally carried out. In addition, the access door 9 is used as the rotating part, so that the structure can be simplified, in this case, the second electric control box 8 is arranged on the inner wall surface of the access door 9, and the second electric control box 8 can be synchronously moved outwards along with the opening of the access door 9, so that the operation steps are reduced. Of course, the rotating portion may be a separate structure provided on the bottom wall instead of the access door 9, and when there is a maintenance need for the second electronic control box 8, the operator performs an operation of rotating the rotating portion separately to expose the second electronic control box 8.
