Description

Technical Field

[0001] The utility model relates to the technical field of louvers, and in particular to a large-air-volume waterproof upper air-outlet louver and an energy storage inverter-boosting integrated machine. Background Art

[0002] The electronic devices inside existing electrical cabinets generate a lot of heat, and need to be dissipated through specially designed heat dissipation structures to prevent the devices from being damaged due to excessive heat generation. Generally speaking, a fan is installed inside the electrical cabinet, which can absorb cold air from the outside. The cold air takes away the heat after passing through the heat-generating electronic devices and is discharged through the air outlet duct. In the process, since the air outlet duct is connected to the outside, sand, rainwater, etc. from the outside can easily enter the cabinet through the air outlet, which can easily cause damage to the internal devices or further aggravate the heating. For this reason, existing electrical cabinets will be equipped with shutters at the position of the air outlet, and the blades of the shutters can prevent sand and rainwater from entering the cabinet.

[0003] The current cabinet air outlet louvers need to be able to prevent rain from entering the cabinet or gathering on the louvers, so the louvers are all tilted downward, so that when rain hits the louvers, it can flow away along the tilt angle of the louvers. However, this waterproof structure of the louvers will cause the air outlet direction of the cabinet to be tilted downward when the cabinet is out, and the hot air will accumulate at the bottom of the cabinet, which is not conducive to the internal fan of the cabinet to inhale cold air, nor is it conducive to the natural circulation of hot and cold air, which will cause the heat dissipation efficiency of the cabinet to decrease. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a large air volume waterproof upper air outlet louver and an energy storage inverter boost all-in-one machine, wherein the louver can improve the heat dissipation efficiency of the energy storage inverter boost all-in-one machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Technical Solution 1: A large-air-volume waterproof upper air-outlet louver, comprising: a frame body, comprising two side frames located at left and right positions; a plurality of blade groups, each blade group comprising a first blade and a second blade arranged in sequence from back to front, each blade group being fixedly arranged in the frame body at a preset distance in the up-down direction, and both left and right ends thereof being connected to the two side frames of the frame body; the first blades are connected in sequence from back to front with a first guide plate inclined downward and a second guide plate inclined upward, and the second blades are connected in sequence from back to front with a third guide plate inclined downward and a fourth guide plate inclined upward; wherein an air passage is formed between adjacent blade groups in the up-down direction, and the fourth guide plate is used to guide the wind flow to turn upward.

[0007] Technical solution two based on technical solution one: In the blade group, the first blade and the second blade are arranged at intervals in the front-rear direction and form a water-falling gap.

[0008] Technical solution three based on technical solution two: In the blade group, the upper edge of the third guide plate is higher than the upper edge of the second guide plate.

[0009] Technical solution four based on technical solution three: In the blade group, the inclination angle of the third guide plate relative to the up-down direction is greater than or equal to 45 degrees, and its upper edge is close to or extends beyond the extension plane of the second guide plate.

[0010] Technical solution five based on technical solution four: The cross-sectional shapes of the first blade and the second blade in the vertical cross-section perpendicular to the left-right direction are the same.

[0011] Technical solution six based on any one of technical solutions one to five: The first blade and the second blade are provided with drain holes at the bottom.

[0012] Technical solution seven based on technical solution six: The drain holes are in the shape of long strips extending in the left-right direction.

[0013] Technical solution eight based on technical solution seven: The first blade and the second blade are provided with a plurality of drain holes arranged in the left-right direction.

[0014] Technical solution nine based on technical solution eight: The frame body further includes a bottom frame, and the bottom frame is provided with a plurality of water outlets.

[0015] In addition, the present utility model also provides technical solution ten: An energy storage inverter boost integrated machine, which includes: an energy storage converter; a transformer chamber for placing a transformer therein, the transformer being electrically connected to the energy storage converter; and the large-air-volume waterproof upper-outlet louvers according to any one of technical solutions one to nine, which are installed on the upper part of the transformer chamber.

[0016] As can be seen from the above description of the present utility model, compared with the prior art, the present utility model has the following beneficial effects:

[0017] Technical solution one provides a large-air-volume waterproof upward air outlet louver. The louver is provided with a number of blade groups. Each blade group includes a first blade and a second blade. The first blade includes a first guide plate and a second guide plate. The second blade includes a third guide plate and a fourth guide plate. The blade groups cooperate with each other to form an air passage. The rear side of this air passage is the air inlet end, and the front side is the air outlet end. After the air flow inside the cabinet enters from the rear end of the air passage, it first moves downward obliquely under the action of the first guide plate, then moves upward obliquely under the action of the second guide plate, then moves downward obliquely under the action of the third guide plate, and finally moves upward obliquely under the action of the fourth guide plate, so that the air flow is guided upward and discharged, which can avoid the accumulation of hot air at the lower side position of the cabinet and affect the heat dissipation of the cabinet; with this air duct setting, the air flow will not have too large a turning, the kinetic energy attenuation of the air flow is small, and more air volume can pass through per unit time, achieving the effect of large-air-volume air outlet; at the same time, the first blade and the second blade arranged correspondingly in the front-rear direction are provided. The third guide plate on the second blade can play a first-level water blocking role, and then the first guide plate on the first blade can play a second-level water blocking role. Moreover, the distance between the front end and the rear end of the air passage is relatively far. After the rainwater and the like are blocked by the second blade and the first blade, it is difficult to reach the rear side of the louver, thus playing a waterproof role; at the same time, the fourth guide plate can also prevent the rainwater from splashing upward from the ground from entering the louver interior.

[0018] In technical solution two, the first blade and the second blade in the blade group are not joined together, but are spaced apart from each other to form a water drainage gap. When there is a lot of rainwater outside and the second blade accumulates water, when this accumulated water overflows, it can flow downward from the first gap, reducing the impact on the first blade and the interior of the louver.

[0019] In technical solution three, the upper edge of the third guide plate in the blade group is higher than the upper edge of the second guide plate. With this setting, when the air flow passes through the water drainage gap from the position of the first blade and is about to reach the position of the second blade, the air flow will be blocked by the third guide plate, so as to turn and flow along the second blade, avoiding too much air flow flowing upward along the water drainage gap and affecting the air flow in the air passage at other positions.

[0020] In technical solution four, the inclination angle of the third guide plate is set, and the upper edge of the third guide plate is made to be close to or exceed the extension plane of the second guide plate. Here, the extension plane refers to the plane where the second guide plate is located as a plate-like structure. In essence, it can be understood as a limitation on the upper edge position of the third guide plate. This limitation makes it that when the air flow reaches the water drainage gap, most of it will be blocked by the third guide plate, reducing the escape of the air flow from the water drainage gap and ensuring to the greatest extent that most of the air flow flows along the air passage.

[0021] In Technical Solution Five, the shapes of the first blade and the second blade are made the same. Only one type of mold is needed during manufacturing, which can reduce the manufacturing cost and improve the manufacturing efficiency.

[0022] In Technical Solution Six, drainage holes are provided at the bottoms of the first blade and the second blade. When rainwater falls on the first blade and the second blade, the rainwater will flow away through the drainage holes, preventing water accumulation on the louvers. By setting the drainage holes at the bottom of the blades, even a small amount of accumulated water can be drained smoothly, and the leakage of wind flow from the positions of the drainage holes can be reduced.

[0023] In Technical Solution Seven, the drainage holes are set in a long strip shape extending in the left - right direction. Compared with circular holes, it can have a larger water - passing area. Compared with a long strip shape extending up and down, it can quickly drain water even when there is a small amount of water. At the same time, the air - passing area is small, and a large amount of hot air will not leak from the drainage holes.

[0024] In Technical Solution Eight, multiple drainage holes are provided, which can improve the drainage efficiency. When there are depressions where water is likely to accumulate due to processing accuracy problems at certain positions, sufficient drainage can also be achieved.

[0025] In Technical Solution Nine, a water outlet is also provided on the bottom frame. The rainwater flowing down from each blade group will gather on the bottom frame and drain away through the water outlet.

[0026] Technical Solution Ten provides an energy storage inverter boost integrated machine. Since this energy storage inverter boost integrated machine adopts the above - mentioned large - air - volume waterproof upward - blowing louvers, it can not only provide waterproof protection for the transformer cabin but also discharge the hot air upward, improving the heat dissipation efficiency.

[0040] Embodiment 1:

[0041] An embodiment of the present utility model provides a large-air-volume waterproof upward air outlet louver 1. Refer to Figure 1 , Figure 1 which shows the side cross-sectional structure of the louver 1. Here, the side cross-sectional schematic diagram is formed by making a vertical side cross-sectional view of the louver 1 with the air outlet surface of the louver 1 as the front, the air inlet surface as the rear, and the arrangement direction of the blades inside the louver 1 as the up-down direction.

[0042] Refer to Figure 1 , in this embodiment, the louver 1 includes a frame body 2 and a plurality of blade groups 4.

[0043] Among them, refer to Figure 4 , the frame body 2 includes side frames 3, a bottom frame 14 and a top frame 18. The side frames 3 are located on the left and right sides, the bottom frame 14 is located at the bottom, and the top frame 18 is located at the top. The structure of the frame body 2 is a conventional structure of the louver 1, and its form and function are well known to those skilled in the art, so they will not be elaborated here. It is easy to understand that the frame body 2 encloses to form a frame structure, and the blade groups 4 of the louver 1 are installed inside this frame structure, thus forming an air outlet louver 1 with fixed blade positions. At the same time, refer to Figure 1 and Figure 4 , a ventilation net 16 and a filter cotton 17 are further provided at the rear side of the frame body 2. The filter cotton 17 is used to prevent foreign objects from entering the inside of the louver 1, and the ventilation net 16 is used to fix the filter cotton 17 and allow the air flow to pass through.

[0044] Refer to Figure 1 , the louver 1 includes a plurality of blade groups 4. Each blade group 4 includes a first blade 5 and a second blade 6 arranged in sequence from the rear to the front. The blade groups 4 are fixedly arranged in the frame body 2 at preset intervals in the up-down direction, and both the left and right ends thereof are connected to the side frames 3 on both sides of the frame body 2; the first blade 5 is successively connected with a first guide plate 7 inclined downward and a second guide plate 8 inclined upward from the rear to the front, and the second blade 6 is successively connected with a third guide plate 9 inclined downward and a fourth guide plate 10 inclined upward from the rear to the front. Among them, an air passage 11 is formed between the blade groups 4 adjacent in the up-down direction, and the fourth guide plate 10 is used to guide the air flow to turn upward.

[0045] Specifically, the louver 1 includes a plurality of blade groups 4. Each blade group 4 includes a first blade 5 and a second blade 6. At the same time, these blade groups 4 are arranged at intervals in the up and down direction, and both the first blade 5 and the second blade 6 are generally in a "V" shape. These first blades 5 and second blades 6 can be made of metal or plastic, and are fixedly installed on the frame 2 in an appropriate manner according to the corresponding material. At the same time, the first blade 5 and the second blade 6 can be integrally formed, or each guide plate can be formed separately and then connected into one body by means such as welding.

[0046] With such a setting, between adjacent blade groups 4, that is, adjacent first blades 5 and second blades 6 cooperate to form a smooth air passage 11. Refer to Figure 1 . The air flow inside the louver 1 enters the air passage 11 from the rear end of the first blade 5. When it reaches the stage of the air passage 11 defined by the first blade 5, and then reaches the stage of the air passage 11 defined by the second blade 6, and finally leaves the air passage 11 from the front end of the second blade 6. During this process, the guide plates on the first blade 5 and the second blade 6 play a role in guiding the air flow to turn and flow. Among them, after the air flow enters from the rear end of the air passage 11, it first moves downward obliquely under the action of the first guide plate 7, then moves upward obliquely under the action of the second guide plate 8, then moves downward obliquely under the action of the third guide plate 9, and finally moves upward obliquely under the action of the fourth guide plate 10, so that the air flow is guided to be discharged upward. Thus, the louver 1 can guide the air flow to discharge upward. When applied to a cabinet, it can avoid hot air accumulating at the lower side position of the cabinet and affecting the heat dissipation of the cabinet. At the same time, with such a setting of the air duct, the air flow will not have too large a turn, the attenuation of the air flow kinetic energy is small, and the air volume passing through per unit time is more, achieving the effect of large air volume discharge.

[0047] In addition, due to the "V" - shaped shape characteristics of the first blade 5 and the second blade 6, compared with the conventional downward - discharging louver 1, rainwater is more likely to enter the louver 1 from the position of the second blade 6. However, by setting the third guide plate 9 on the second blade 6 and setting the first blade 5 at the same time, under the dual water - blocking effects of the two, the situation where rainwater enters the inside of the louver 1 along the air passage 11 can be reduced. And the first blade 5 and the second blade 6 themselves have a certain width, thus increasing the length of the air passage 11. When rainwater enters the air passage 11, it is easily blocked by the first blade 5 and the second blade 6 and is difficult to reach the inside of the louver 1. And although the fourth guide plate 10 is difficult to block rainwater from entering the air passage 11 when it falls from top to bottom, in the face of rainwater splashed from the ground, the fourth guide plate 10 can well prevent rainwater from splashing into the inside of the louver 1.

[0048] Furthermore, refer to Figure 1 and Figure 2, in the blade group 4, the first blade 5 and the second blade 6 are arranged at intervals in the front - rear direction and form a water - falling gap 12.

[0049] Obviously, in this embodiment, the first blade 5 and the second blade 6 within the same blade group 4 are not connected as a whole in the front - rear direction, but have an interval in the front - rear direction, and this interval forms the water - falling gap 12. Since the blade groups 4 are arranged at intervals in the up - down direction, and the size and structure of the first blade 5 and the second blade 6 in each blade group 4 are the same, the positions of the water - falling gaps 12 in each blade group 4 are also the same. Thus, a long - strip - shaped water - falling channel is formed in the up - down direction of the louver 1. Except for the water - falling gap 12, this water - falling channel actually occupies a part of the air - passing channel 11. When the rainfall is large and the rainwater accumulates on the second blade 6 and overflows from the second blade 6, the rainwater will flow into the water - falling gap 12 and flow along the water - falling channel to the bottom of the louver 1. The setting of the water - falling gap 12 further improves the waterproof ability of the louver 1. Even when the rainfall is large, the rainwater can still be effectively guided to the bottom of the louver 1. Refer to Figure 4 , a plurality of water outlets 15 are arranged on the bottom frame 14 of the louver 1. Through the water outlets 15, the rainwater falling to the bottom of the louver 1 can be quickly discharged to the outside. It should be noted that although the water - falling channel occupies a part of the air - passing channel 11, when the louver 1 discharges air, the air flow is flowing outwards. Therefore, when the water flow passes through the air - passing channel 11, the air flow will instead blow the water flow outwards, and it is difficult for the water flow to reach the inner side of the louver 1 along the air - passing channel 11.

[0050] Furthermore, refer to Figure 2 , in the blade group 4, the upper edge of the third guide plate 9 is higher than the upper edge of the second guide plate 8. It is easy to understand that as a guide plate, its shape and structure are generally plate - shaped. Taking the structures of the first blade 5 and the second blade 6, the rear - side edge of the first guide plate 7 is its upper edge, the front - side edge of the second guide plate 8 is its upper edge, the rear - side edge of the third guide plate 9 is its upper edge, and the front - side edge of the fourth guide plate 10 is its upper edge. There are various situations where the upper edge of the third guide plate 9 is higher than the upper edge of the second guide plate 8. For example, in this embodiment, the position of the second blade 6 is staggered with the position of the first blade 5 in the up - down direction, and the second blade 6 in the same blade group 4 is higher than the first blade 5 in the up - down direction, so that the upper edge of the third guide plate 9 is higher than the upper edge of the second guide plate 8; or, in other embodiments, the length of the third guide plate 9 can be extended longer until the upper edge of the third guide plate 9 is higher than the upper edge of the second guide plate 8.

[0051] Of course, there can be other setting methods. It should be noted that the upper edge of the third guide plate 9 is higher than the upper edge of the second guide plate 8. The precondition for this setting is that there is a water falling gap 12 between the first blade 5 and the second blade 6 in the same blade group 4. If the third guide plate 9 is not specially designed, too much air flow will escape along the water falling gap 12 during the process of the air flow entering the second blade 6 from the first blade 5. After the upper edge of the third guide plate 9 is higher than the upper edge of the second guide plate 8, the air flow in the air passing channel 11 below the second blade 6 will be blocked by the third guide plate 9 after passing through the water falling gap 12, so that the part of the air flow can continue to flow along the air passing channel 11 along the lower side surface of the third guide plate 9.

[0052] In this embodiment, particularly, the inclination angle of the third guide plate 9 relative to the vertical direction is set to be greater than or equal to 45 degrees, and its upper edge is close to or exceeds the extension plane of the second guide plate 8. Such a setting can enable most of the air flow to continue to flow along the air passing channel 11 without escaping from the water falling gap 12.

[0053] Refer to Figure 2 and Figure 3 , the cross-sectional shapes of the first blade 5 and the second blade 6 in the vertical cross-section perpendicular to the left-right direction are the same. At the same time, the lengths of the first blade 5 and the second blade 6 in the left-right direction are also the same. Therefore, the first blade 5 and the second blade 6 are substantially the same structure. During manufacturing, only one mold can be used, thereby reducing the manufacturing cost and improving the manufacturing efficiency.

[0054] Refer to Figure 3 , the first blade 5 and the second blade 6 are provided with drain holes 13 at the bottom. Among them, each drain hole 13 is in a long strip shape extending along the left-right direction, and both the first blade 5 and the second blade 6 are provided with a plurality of drain holes 13 arranged along the left-right direction.

[0055] Specifically, in this embodiment, both the first blade 5 and the second blade 6 are integrally formed metal parts, and the drain holes 13 can be directly stamped at the bottom position of the blades. The bottom of the blade here refers to the pointed corner position of the "V"-shaped blade. Through the drain holes 13, the rainwater entering the blades can be quickly drained downward until the rainwater flows to the bottom of the frame 2, and then is discharged through the water outlet 15 on the bottom frame 14; moreover, by setting the drain holes 13 at the bottom of the blades, even a small amount of accumulated water can be smoothly drained away, and the leakage of the air flow from the position of the drain holes 13 can be reduced. Among them, the drain holes 13 are set in a long strip shape extending in the left-right direction. Compared with the round hole shape, it can have a larger water passing area. Compared with the long strip shape extending up and down, it can be quickly drained when there is a small amount of water; at the same time, the air passing area is small, and a large amount of hot air will not leak from the drain holes 13. At the same time, by setting a plurality of drain holes 13, the drainage efficiency can be improved, and when there are depressions where water is likely to accumulate due to processing accuracy problems at certain positions, the water can also be fully drained.

[0056] In addition, a protective net can be provided at the front side position of the louver 1. The protective net is arranged on the frame 2 and covers the front opening of the frame 2. The protective net can be a metal gauze with small mesh holes and is fixedly installed at the front opening of the frame 2 by means of welding, riveting, etc., which can prevent foreign objects from the outside from entering the inside of the louver 1.

The inside of the transformer chamber 20 is used to place a transformer, and the transformer is connected to the energy storage converter; in addition, it further includes the large-air-volume waterproof upward air outlet louver 1 provided in the above Embodiment 1, which is installed on the upper part of the transformer chamber 20.
