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 , a brief introduction to the casing of the present application is given.
[0034] like Figure 1 and Figure 2 As shown, in order to solve the problem of poor waterproofness of the existing chiller, the casing of the present application includes a frame 1 and a first top plate 2 and a second top plate 3 arranged on the top of the frame 1, and the first top plate 2 and the second top plate 3 are arranged along a first direction ( Figure 1 The first top plate 2 and the second top plate 3 are arranged side by side (in the middle X direction), wherein the side of the first top plate 2 adjacent to the second top plate 3 is provided with a first waterproof structure 21, and the side of the second top plate 3 adjacent to the first top plate 2 is provided with a second waterproof structure 31, and the projection of the first waterproof structure 21 along the vertical direction covers the projection of the second waterproof structure 31 along the vertical direction.
[0035] When installed, the first waterproof structure 21 and the second waterproof structure 31 cooperate with each other to block the gap between the first top plate 2 and the second top plate 3, so that on rainy days, rainwater is blocked by the first waterproof structure 21 and the second waterproof structure 31 and cannot enter the interior of the casing through the gap between the two.
[0036] For the casing of the present application, by providing a first waterproof structure 21 on the first top plate 2 and a second waterproof structure 31 on the second top plate 3, and the projection of the first waterproof structure 21 in the vertical direction covering the projection of the second waterproof structure 31 in the vertical direction, the cooperation relationship between the first waterproof structure 21 and the second waterproof structure 31 can be utilized to prevent rainwater from entering the interior of the casing, thereby improving the waterproof performance of the casing.
[0037] The following combines Figures 1 to 3 to introduce a preferred embodiment of the present application.
[0038] As Figures 1 to 3 shown, in a preferred embodiment, the casing includes a frame 1 and a first top plate 2 and a second top plate 3 provided on the top of the frame 1. There are two first top plates 2 and two second top plates 3 each, and the two first top plates 2 and the two second top plates 3 are arranged in a "field" shape. Among them, the two first top plates 2 are arranged side by side in the second direction ( Figure 1 the Y direction in
[0039] ), and the two second top plates 3 are arranged side by side in the second direction. Each first top plate 2 is adjacent to a second top plate 3 in the first direction.
[0040] Refer to Figure 2 . In the installed state, the second vertical plate 311 is adjacent to the first vertical plate 211 and the second vertical plate 311 is substantially parallel to the first vertical plate 211. The first horizontal plate 212 covers above the second vertical plate 311. Thus, the first vertical plate 211 and the second vertical plate 311 can respectively block rainwater on both sides from entering the casing through the gap between the first vertical plate 211 and the second vertical plate 311, and the first horizontal plate 212 can block rainwater above from entering the casing through the gap between the first vertical plate 211 and the second vertical plate 311.
[0041] The arrangement of the first vertical plate 211 and the first horizontal plate 212 forms an effective waterproof structure, which can prevent rainwater from entering the housing from one side of the first vertical plate 211 and the upper side of the first horizontal plate 212. The first waterproof structure 21 is formed by an integral bending, and the structure is stable and leak-free, which can improve the waterproof effect. The arrangement of the second vertical plate 311 can form an effective waterproof structure, which prevents rainwater from entering the housing from one side of the second vertical plate 311. The second waterproof structure 31 is formed by an integral bending, and the structure is stable and leak-free, which can improve the waterproof effect.
[0042] See also Figure 3 A support beam 11 is provided on the top of the frame 1 extending in the first direction, and the two ends of the support beam 11 extend to the two sides of the frame 1. Preferably, the support beam 11 is formed by bending a sheet metal with a U-shaped cross section. After forming, a drainage groove 111 is formed inside the U-shaped support beam 11. A first gap is formed between two adjacent first top plates 2, and a second gap is formed between two adjacent second top plates 3. After installation, the first gap and the second gap are located above the drainage groove 111.
[0043] Furthermore, a first drainage structure 22 is provided on the side of the first top plate 2 where the first slit is formed. In the present application, the first drainage structure 22 is a lower flange formed by folding the side of the first top plate 2 downward. In the installed state, the two lower flanges extend downward into the drainage groove 111. A second drainage structure 32 is provided on the side of the second top plate 3 where the second slit is formed. In the present application, the second drainage structure 32 is a lower flange formed by folding the side of the second top plate 3 downward. In the installed state, the two lower flanges extend downward into the drainage groove 111.
[0044] The support beam 11 is provided with a drainage groove 111, which can effectively receive rainwater leaking from the first gap between two adjacent first top plates 2 or rainwater leaking between two adjacent second top plates 3, thereby further improving the waterproof performance of the housing. The first drainage structure 22 and the second drainage structure 32 are provided to effectively drain rainwater and prevent splashing when rainwater falls into the drainage groove 111, thereby affecting the waterproof effect.
[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 by combining the first waterproof structure 21 including the first vertical plate 211 and the first horizontal plate 212, and the second waterproof structure 31 including the second vertical plate 311 as an example, the specific forms of the first waterproof structure 21 and the second waterproof structure 31 are not unique, and those skilled in the art can adjust them as long as they can meet the condition that the vertical projection of the first waterproof structure 21 covers the vertical projection of the second waterproof structure 31. For example, the first waterproof structure 21 can also be an inclined sheet metal, which extends obliquely and covers the second waterproof structure 31 below it. For another example, the first vertical plate 211 in the first waterproof structure 21 has a certain angle with the vertical direction, and the first horizontal plate 212 has a certain angle with the first horizontal direction, as long as the extension direction of the first vertical plate 211 and the second horizontal plate is roughly along the vertical and horizontal directions. For another example, the first waterproof structure 21 can also be in a curved form, such as an arc, and the arc covers the second waterproof structure 31 below it. For another example, the second vertical plate 311 may also form a certain angle with the vertical direction, or the second waterproof structure 31 may further include a second transverse plate in addition to the second vertical plate 311 , and the second transverse plate extends in the horizontal direction and is located below the first transverse plate 212 .
[0047] For example, in another replaceable embodiment, although the first waterproof structure 21 and the second waterproof structure 31 are both formed by integral bending, this forming method is not necessary. In other embodiments, at least one of the two can also be formed by screwing, welding, etc. Of course, such a forming method will reduce the waterproof performance compared to the integral bending method.
[0048] For example, in another replaceable embodiment, although the above embodiment is introduced in conjunction with the example in which two first top plates 2 and two second top plates 3 are provided, the number of the first top plates 2 and the second top plates 3 is not restrictive. In other embodiments, one first top plate 2 and one second top plate 3 can also be provided, or three or more can be provided at the same time. Of course, the number of the first top plates 2 and the second top plates 3 can also be different.
[0049] For example, in another replaceable embodiment, the provision of the support beam 11 is only preferred and may not be provided. Of course, if the support beam 11 is not provided when multiple first top plates 2 and multiple second top plates 3 are provided, the waterproof performance of the casing will be reduced.
[0050] For another example, the U-shaped cross section of the support beam 11 is only a possible implementation method. On the premise that the drainage groove 111 can be formed, those skilled in the art can adjust the specific cross-sectional shape of the support beam 11 so that the present application is applicable to more specific application scenarios. For example, the cross section of the support beam 11 can also be "N" shaped or "mountain" shaped.
[0051] For another example, the provision of the first drainage structure 22 and the second drainage structure 32 is not necessary. In other embodiments, those skilled in the art may selectively omit at least one of the two so that the present application is applicable to more specific application scenarios.
[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 implementation, the evaporative cooling unit of the present application is an integrated evaporative condensing chiller, which includes a host unit and an evaporative cooling heat exchange unit, wherein the housing in the above implementation is applied to the host unit. In this way, in rainy days and other conditions, the housing can effectively prevent rainwater from entering, preventing the host and electronic control components from being damp or flooded.
[0055] The evaporative cooling unit of the present application, by setting a first waterproof structure 21 on the first top plate 2 and a second waterproof structure 31 on the second top plate 3, and the projection of the first waterproof structure 21 in the vertical direction covers the projection of the second waterproof structure 31 in the vertical direction, can utilize the matching relationship between the first waterproof structure 21 and the second waterproof structure 31 to prevent rainwater from entering the interior of the casing, thereby improving the waterproof performance of the casing.
[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.
[0057] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. 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.
