For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0033] First refer to Figure 1 and Figure 2 , the casing of the present application is described.

[0034] like Figure 1 and Figure 2 As shown, in order to solve the problem that the lifting belt of the chiller will squeeze the sheet metal parts near the spray pipe and cause the sheet metal parts to deform during the lifting process, the casing of the present application includes a main casing 1 and a cover casing 2. The top surface of the main casing 1 is provided with an opening 11, and the opening 11 has an inner edge adjacent to the outer edge of the top surface of the main casing 1. The cover casing 2 is arranged on the top surface of the main casing 1 and covers the opening 11, wherein the first side wall of the cover casing 2 corresponding to the inner edge is arranged obliquely.

[0035] In a possible hoisting process, the hoisting belt extends upward from the bottom of the main housing 1 through the opposite sides of the main housing 1, and after passing through the two outer sides of the top of the main housing 1, the two ends of the hoisting belt are gathered inward and hung on the hook. When passing through one outer side, the hoisting belt extends upward roughly along the inclined direction of the first side wall of the cover 2 without contacting the first side wall.

[0036] The casing of the present application can avoid squeezing of the cover shell 2 by the lifting belt during lifting by tilting the first side wall of the cover shell 2 close to the outer edge of the main shell 1 and extending along the first direction, thereby ensuring the installation effect and user experience.

[0037] Combine the following Figures 1 to 3 , a preferred implementation of the present application is introduced.

[0038] like Figures 1 to 3 As shown, in a preferred embodiment, the housing includes a main housing 1 and a cover 2. The main housing 1 is a hollow cuboid, and an opening 11 is provided on the top thereof for a spray pipe 3 to spray cooling water downward. The opening 11 is rectangular, and the two inner edges of the rectangular opening are respectively adjacent to the two outer edges at the corners of the top surface of the main housing 1.

[0039] Reference Figure 1 and Figure 3, the cover shell 2 is formed by connecting a plurality of sheet metal parts. Specifically, the cover shell 2 includes a top plate 21, a first side plate 22, a second side plate 23, a third side plate 24, a fourth side plate 25 and a support beam 26, wherein the first side plate 22, the second side plate 23, the third side plate 24 and the fourth side plate 25 are all connected to the lower side of the top plate 21, and the first side plate 22, the second side plate 23, the third side plate 24 and the fourth side plate 25 are connected end to end in sequence. Among them, two first side plates 22 and three side plates 24 are respectively provided, and one second side plate 23 and four side plates 25 are provided, and the two first side plates 22 are adjacent to each other on one side butt joint, and the two first side plates 22 are away from each other on one side respectively connected to one end of the second side plate 23 and one end of the fourth side plate 25. The two third side plates 24 are adjacent to each other on one side butt joint, and the two third side plates 24 are away from each other on one side respectively connected to the other end of the second side plate 23 and the other end of the fourth side plate 25. Two top plates 21 are provided, and the two top plates 21 are butt-jointed at one side close to each other, and the other three side edges of one top plate 21 are respectively connected to a first side plate 22, a second side plate 23 and a third side plate 24, and the other three side edges of the other top plate 21 are respectively connected to another first side plate 22, a fourth side plate 25 and another third side plate 24.

[0040] The connection method between the above-mentioned side panels and the top panel 21 is not limited in this application, and those skilled in the art can choose it based on different application scenarios. For example, the top panel 21 and the side panels, and the side panels and the side panels can be connected by welding, screwing, bonding, etc., or the above-mentioned methods can be mixed to achieve the connection. For example, when screw connection is adopted, the ends and the top of each side panel can be provided with flanges inward or outward, and then connection holes are opened on the flanges, and the side panels and the side panels or the side panels and the top panel 21 are fixedly connected by passing threaded fasteners through the connection holes.

[0041] Preferably, a first folded edge 221 is formed on the upper side of the first side panel 22, a second folded edge 222 is formed on the lower side of the first side panel 22, the first side panel 22 is connected to the lower side of the top panel 21 through the first folded edge 221, and the first side panel 22 is connected to the upper side of the top surface of the main housing 1 through the second folded edge 222. The second side panel 23 and the fourth side panel 25 are arranged as inclined surfaces at one end close to the first side panel 22, and the plate surface between the first folded edge 221 and the second folded edge 222 of the first side panel 22 is inclinedly abutted against the inclined surfaces of the second side panel 23 and the fourth side panel 25. In this way, the plate surfaces of the two first side panels 22 are arranged obliquely and constitute the first side wall of the above-mentioned cover shell 2.

[0042] In one embodiment, the inclination angle of the first side wall is any value between 30° and 60°, and more preferably, the inclination angle of the first side wall is 45°. After repeated tests, verifications, analyses and comparisons by the inventors, when the inclination angle of the first side wall is set between 30° and 60°, especially when it is set at about 45°, the hoisting belt can effectively avoid squeezing the cover 2 during the hoisting process.

[0043] Continue to see Figure 3 , three support beams 26 are provided in the present application, and the two ends of each support beam 26 are respectively connected to the first side plate 22 and the third side plate 24. Among the three support beams 26 of the present application, one end of the support beam 26 located in the middle is simultaneously connected to the two first side plates 22, and the other end is simultaneously connected to the two third side plates 24, and the remaining two support beams 26 are respectively connected between a pair of first side plates 22 and the third side plates 24. The present application does not limit the connection method, and those skilled in the art can freely choose, such as welding, bonding, screwing, etc. to achieve the connection between the support beam 26 and the first side plate 22 and the third side plate 24.

[0044] The configuration of the cover 2 formed by connecting a plurality of sheet metal parts is conducive to reducing the manufacturing difficulty of the cover 2 and reducing the replacement and maintenance costs of the cover 2. The configuration of the first folded edge 221 facilitates the connection between the first side plate 22 and the top plate 21. The configuration of the second folded edge 222 facilitates the connection between the first side plate 22 and the main housing 1. The configuration of the support beam 26 can enhance the connection strength of the first side plate 22 and improve the overall stability of the cover 2.

[0045] It should be noted that the above preferred implementations are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may adjust the above settings so that the present application can be applied to more specific application scenarios.

[0046] For example, in an alternative embodiment, although the above embodiment is described in combination with the example that the opening 11 is a rectangular opening and the rectangular opening has two inner edges that are adjacent to the outer edges of the top of the main shell 1, the specific shape and setting position of the opening 11 are not fixed, and those skilled in the art can adjust it based on specific needs. For example, the opening 11 can also be a square or other polygon; the opening 11 only needs to have one inner edge adjacent to the outer edge of the top of the main shell 1. Of course, the inner edge is preferably the inner edge that the hoisting belt passes through during the hoisting process. In other words, the inner edge is usually selected from the long side of the rectangular opening, which is more in line with the hoisting requirements.

[0047] For another example, although the above embodiment is introduced in combination with the inclination angle of the first side wall being between 30°-60°, the specific inclination angle of the first side wall is not restrictive, and technicians in this field can adjust it based on specific design requirements, as long as the adjusted angle can prevent the cover 2 from being squeezed and deformed by the lifting belt during the lifting process, even if the lifting belt may be in contact with the cover 2 during the lifting process.

[0048] For another example, in another alternative embodiment, although the above embodiment is described in conjunction with the case 2 being formed by connecting a plurality of sheet metal parts, the specific formation method of the case 2 is not unique, and those skilled in the art can make adjustments based on specific application scenarios. For example, the case 2 can also be integrally formed, or the case 2 can also be made of non-metallic materials, etc.

[0049] For another example, in another alternative embodiment, the specific composition of the housing 2 is not unique, and those skilled in the art can adjust it based on the specific application scenario. For example, the number of the first side panel 22 and the third side panel 24 can be set to one, or more. For another example, the second side panel 23 and the fourth side panel 25 can also be set to multiple. For another example, the top panel 21 is described by taking two as an example, but the number of the top panels 21 can also be one, three, four, etc.

[0050] For another example, in another alternative embodiment, the specific structure of the first side plate 22 is not fixed, and those skilled in the art may adjust its structure under the premise of satisfying its inclined setting. For example, at least one of the first folded edge 221 and the second folded edge 222 may be omitted, or the first folded edge 221 may be connected to the upper side of the top plate 21, and the second folded edge 222 may be connected to the lower side of the top surface of the main housing 1.

[0051] For example, in another alternative embodiment, the support beam 26 is not required, and those skilled in the art can choose whether to set the support beam 26 based on the specific application scenario. Under the premise of setting the support beam 26, the number and setting position of the support beam 26 can be adjusted, and such adjustment does not deviate from the principle of the present application.

[0052] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0053] The present application also provides an evaporative cooling unit, which includes a casing according to any one of the above-mentioned preferred technical solutions.

[0054] In a possible embodiment, the evaporative cooling unit of the present application is an integrated evaporative condensing chiller, which includes a main unit and an evaporative cooling heat exchange unit, wherein the casing in the above embodiment is applied to the evaporative cooling heat exchange unit, and a accommodating cavity is formed between the main shell 1 and the cover shell 2 of the casing, and a spray pipe 3 is arranged in the accommodating cavity to spray cooling water on the evaporative cooling heat exchanger arranged inside the casing and located below the spray pipe 3.

[0055] The evaporative cooling unit of the present application can avoid squeezing of the cover 2 by the lifting belt during the lifting process by tilting the first side wall of the cover 2 close to the outer edge of the main shell 1 and extending along the first direction, thereby ensuring the installation effect and user experience.

[0056] Of course, the evaporative cooling unit is an integrated evaporative condensing chiller for exemplary purposes only, and those skilled in the art may apply the present application to other application scenarios without departing from the principles of the present application. For example, the present application may also be applied to a split evaporative condensing chiller, an integrated evaporative condensing heat pump unit, a split evaporative condensing heat pump unit, and the like.

For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0058] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
