Description

Technical Field

[0001] The utility model relates to the field of cooling structures, in particular to a drainage device. Background Art

[0002] In the design of air-cooled energy storage liquid cooling units, the selection of air inlet and outlet air patterns is a key factor in optimizing the heat exchange process. This design directly determines the energy efficiency and operational stability of the entire system. The design and optimization of the air inlet and outlet patterns play a vital role in the condenser's heat dissipation process. Common air inlet and outlet patterns for air-cooled liquid cooling units include rear-inlet, front-outlet, side-inlet, top-outlet, and same-side-inlet and outlet. Each air inlet and outlet pattern has its own unique characteristics and applicable scenarios.

[0003] Currently, energy storage systems are mainly based on container-type layouts. Since the sides and top are closed, only one surface is left to provide air inlet and outlet conditions for the unit. Therefore, same-side air inlet and outlet can be used as the optimal choice for the air inlet and outlet method of energy storage liquid-cooled units.

[0004] While the same-side air inlet and outlet design reduces space requirements and system size, making it ideal for containerized energy storage systems with only one open side, it can also easily cause system overheating and short circuiting. This problem arises because the air inlet and outlet are arranged on the same side. The cold air drawn in by the inlet and the hot air discharged by the outlet easily mix with each other, causing the temperature of the cold air at the inlet to rise, which in turn reduces the cooling effect of the unit and ultimately causes the system to overheat and short circuit. This problem not only affects the cooling effect of the condenser, but also reduces the energy efficiency and stability of the system due to the continuous increase in unit temperature. Utility Model Content

[0005] The purpose of the present utility model is to provide a drainage device in order to overcome the defect of the above-mentioned prior art that the air inlet and the air outlet are arranged on the same side, the cold air sucked in by the air inlet and the hot air discharged by the air outlet are easily mixed with each other, resulting in the temperature of the cold air at the air inlet rising and the heat dissipation effect of the unit being deteriorated.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A drainage device, comprising a drainage structure, for an air-cooled energy storage liquid cooling unit, wherein the air inlet and the air outlet of the air-cooled energy storage liquid cooling unit are located on the same side, the drainage structure is located outside the air outlet, and the drainage structure comprises a fixed outer frame and a plurality of drainage blades, each of the drainage blades being fixed in parallel within the fixed outer frame;

[0008] The length of the drainage path on the upper edge of the drainage blade is smaller than the drainage path on the lower edge. The lower edge of the drainage blade away from one end of the air-cooled energy storage liquid cooling unit is bent toward the side away from the air inlet, and the drainage blade is inclined toward the side away from the air inlet.

[0009] Preferably, the guide blade comprises a straight segment, an arc segment and a curved segment connected in sequence, and the sum of the lengths of the arc segment and the curved segment is greater than the length of the straight segment.

[0010] Preferably, the guide blades are distributed at equal intervals within the fixed outer frame.

[0011] Preferably, the distance between adjacent guide blades is 45-55 mm.

[0012] Preferably, the angle between the guide blades and the horizontal direction is 19-21 degrees.

[0013] Preferably, the guide blade is an airfoil, and the blade attack angle of the guide blade is 19-21 degrees.

[0014] Preferably, the angle between the guide blade and the horizontal direction is equal to the blade attack angle of the guide blade.

[0015] Preferably, the fixed outer frame is of a step-type, and the large port of the fixed outer frame is connected to an air-cooled energy storage liquid cooling unit.

[0016] Preferably, the fixed outer frame is bolted to the air-cooled energy storage liquid cooling unit.

[0017] Preferably, the guide blades are welded inside a fixed outer frame.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] (1) The guide blades of this solution are arranged slightly upwardly as a whole, which can guide the hot air at the outlet upward. The lower edge of the guide blade is bent toward the side away from the air inlet, so that the hot air flowing through the lower edge of the blade has a longer airflow path and its own flow speed increases. The airflow path at the upper edge of the blade is short, and the hot air flow speed is relatively slow. When the wind speed at the curved lower edge increases, the pressure drops, thus forming a small low-pressure area. Under the action of the pressure difference, the hot air at the upper edge flows upward, ensuring that the hot air at the end of the blade is blown out obliquely upward along the curved surface, further ensuring the separation of hot and cold air.

[0020] The airflow path of the air outlet is optimized by the guide vanes, which effectively alleviates the system overheating and short-circuit problem existing in the liquid-cooled units with air inlet and outlet on the same side, reduces the mixing of cold and hot air, ensures the heat dissipation efficiency of the condenser, reduces overheating, and improves the performance of the liquid-cooled units with air inlet and outlet on the same side.

[0021] (2) This solution optimizes the structure of the guide blades and sets them slightly tilted. Under the premise of ensuring the air intake of the guide structure, the hot air is guided upward. In addition, combined with the fixed outer frame of the step-type structure, it can play an auxiliary role in guiding the hot air at the air outlet, further improving the upward guidance effect of the guide blades. This guide structure improves the heat dissipation effect of the condenser of the air-cooled energy storage liquid cooling unit, enhances the system stability, extends the life of the unit, and improves the operating efficiency of the unit.

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0034] Example 1

[0035] like Figure 1 As shown, this embodiment provides a drainage device, including a drainage structure 2, for an air-cooled energy storage liquid cooling unit 1. The air inlet and air outlet of the air-cooled energy storage liquid cooling unit 1 are located on the same side, and the drainage structure 2 is located outside the air outlet. The drainage structure 2 includes a fixed outer frame 21 and a plurality of drainage blades 22. Each drainage blade 22 is fixed in parallel in the fixed outer frame 21.

[0036] The length of the drainage path on the upper edge of the drainage blade 22 is shorter than the drainage path on the lower edge. The lower edge of the drainage blade 22 away from the air-cooled energy storage liquid cooling unit 1 is bent toward the side away from the air inlet, and the drainage blade 22 is inclined toward the side away from the air inlet.

[0037] The guide vanes are arranged at a slight upward angle to direct hot air from the outlet upward. The lower edge of the guide vane is curved away from the air inlet, causing the hot air flowing through the lower edge of the vane to have a longer airflow path and accelerate its velocity. The airflow path at the upper edge of the vane is shorter, and the hot air velocity is relatively slow. As the air velocity at the curved lower edge increases, the pressure drops, forming a small low-pressure area. This pressure differential forces the hot air at the upper edge to flow upward, ensuring that the hot air at the end of the vane is blown diagonally upward along the curved surface, further ensuring the separation of hot and cold air.

[0038] The airflow path of the air outlet is optimized through the guide blades, which effectively alleviates the overheating and short-circuit problem of the liquid-cooled unit with air inlet and outlet on the same side, reduces the mixing of cold and hot air, ensures the heat dissipation efficiency of the condenser, reduces overheating, and improves the performance of the liquid-cooled unit with air inlet and outlet on the same side.

[0039] Optionally, the guide blade 22 includes a straight segment 23 , an arc segment 24 and a curved segment 25 that are sequentially connected to each other, and the sum of the lengths of the arc segment 24 and the curved segment 25 is greater than the length of the straight segment 23 .

[0040] In a preferred embodiment, the fixed outer frame 21 is of a step-type, and a large port of the fixed outer frame 21 is connected to the air-cooled energy storage liquid cooling unit 1 .

[0041] By optimizing the structure of the guide blades and setting them slightly tilted, the hot air can be guided upward while ensuring the air intake of the guide structure. In addition, combined with the fixed outer frame of the terraced structure, it can play an auxiliary role in guiding the hot air at the air outlet, further improving the upward guidance effect of the guide blades. This guide structure improves the heat dissipation effect of the condenser of the air-cooled energy storage liquid cooling unit, enhances the system stability, extends the life of the unit, and improves the operating efficiency of the unit.

[0042] Specifically, if Figures 3 to 5 As shown, the guide blades 22 are connected to the metal fixed outer frame 21 by welding. During welding, the leading edge of the blade faces outward and the trailing edge faces inward. The blade attack angle is selected to be 20°, taking into account the aerodynamic characteristics to ensure the guide effect of the blade; the guide blades 22 are tilted upward, and the angle between the blades and the horizontal direction is selected to be 20°, so that the blades can guide air upward while taking into account the air intake effect of the guide structure to ensure the overall heat dissipation effect of the guide structure. The guide blades 22 are arranged at equal intervals of 50 mm. The fixed outer frame 21 of the guide device is connected to the box outside the air outlet of the liquid cooling unit by bolts.

[0043] like Figure 4As shown, cold air enters the unit's "U-shaped" circulation airflow path from the air inlet 3 at the unit's bottom. It first passes through the refrigeration unit 5 at the bottom, then flows through the middle partition into the upper layer of the unit, sweeping across the heat exchange tubes of the "V-shaped" condenser 6 to exchange heat with the condenser. After the heat exchange is completed, the hot air is blown by the fan to the air outlet 4, and then the flow direction is changed by the diversion structure 2. Because the air pressure is higher near the windward side of the diversion blades and lower near the leeward side, the air is ultimately blown out at an upward angle, reducing mixing with the cold air from the air inlet, reducing performance degradation caused by the mixing of cold and hot air, and alleviating the problem of overheating and short circuiting of the unit.

[0044] In summary, this technical implementation scheme, through the design of a novel airflow device, optimizes the airflow path at the air outlet, effectively alleviating the system overheating and short-circuiting issues that often occur in liquid-cooled units with same-side air inlet and outlet. This improves the performance of these units. By optimizing the airflow path, mixing of hot and cold air is reduced, ensuring efficient condenser heat dissipation, reducing overheating, enhancing system stability, extending unit life, and improving unit operating efficiency.

[0045] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
