Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat dissipation equipment, and particularly relates to a housing and a heat dissipation equipment having the same. Background Art
[0002] Structures similar to louvers are widely used in sheet metal parts, and are usually designed on parts such as electrical boxes, electrical control boxes, and unit enclosures. Their function is to allow air to flow between the inside and outside of the unit or electrical appliance to dissipate heat for the unit. At the same time, the blades of the structure similar to the louver can block external rainwater and the like from entering the interior of the unit, playing a waterproof role.
[0003] The drawback of the structure similar to the louver is that its own blades are prone to corrosion. The main reason is that the lower side of the blade is mostly a flat structure, which makes it easy for water flow to adhere to and drip on the swing blade. And the lower side of the blade is a cross-section formed by punching. During use, the base material of the cross-section is exposed, and it is easily corroded and rusted by the dripping liquid for a long time, affecting the overall appearance quality and protection effect. Summary of the Utility Model
[0004] Therefore, the utility model provides a housing, which can solve the technical problem that the lower side of the blade of the structure similar to the louver applied on the existing sheet metal part is mostly a flat structure, water flow is easy to adhere to and drip on the blade, and the lower side of the blade is a cross-section formed by punching, and it is easily corroded and rusted by the dripping liquid for a long time.
[0005] To solve the above problems, the utility model provides a housing, including: a housing body and a swing blade. A ventilation opening is formed on the housing body. The swing blade is rotatably connected to the housing body. The swing blade is used to open or close the ventilation opening. The swing blade has a drainage part, and along the width direction of the swing blade, the drainage part gradually narrows.
[0006] In some embodiments, the drainage part gradually narrows to form a sharp angle.
[0007] In some embodiments, the drainage part has a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface are joined to form the sharp angle. The first inclined surface extends from one side edge of the swing blade to the tip of the sharp angle, and the second inclined surface extends from the other side edge of the swing blade to the tip of the sharp angle.
[0008] In some embodiments, the included angle formed between the first inclined surface and the second inclined surface is e, and 150° ≤ e ≤ 170°.
[0009] In some embodiments, the swing blade further has a main body part. The upper side of the main body part is rotatably connected to the housing body. The drainage part is located on the lower side of the main body part. The shape and size of the ventilation opening match the shape and size of the swing blade.
[0010] In some embodiments, the main body portion has a cuboid structure, the width of the main body portion is c, the maximum width of the swinging blade is b, and 1 / 2 ≤ (c / b) < 2 / 3.
[0011] In some embodiments, when the swinging blade is in the state of opening the ventilation opening, the angle by which the swinging blade rotates relative to the housing body is f, and 40° ≤ f ≤ 50°.
[0012] In some embodiments, the number of the ventilation openings is multiple, and the ventilation openings are sequentially arranged at intervals along the height direction of the housing body. The number of the swinging blades is also multiple. Each swinging blade is rotatably connected to the housing body, and each swinging blade corresponds to each ventilation opening.
[0013] In some embodiments, when each swinging blade is in the state of closing the ventilation opening, the shortest distance between two adjacent swinging blades along the height direction of the housing body is d, and 2 mm ≤ d ≤ 5 mm.
[0014] The present utility model further provides a heat dissipation device, including the aforementioned housing.
[0015] A housing provided by the present utility model and a heat dissipation device having the same have the following beneficial effects:
[0016] In this application, by improving the swinging blade on the housing, the swinging blade has a drainage portion, and the drainage portion gradually narrows along the width direction of the swinging blade. Therefore, when rainwater hits the swinging blade, water droplets will converge to the narrowest part of the drainage portion under the action of gravity, and then gather and fall, so that the water droplets will not contact the swinging blade for a long time, thereby significantly alleviating the corrosion of the cross section of the swinging blade by water and extending the service life of the swinging blade.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0026] In the description of the present utility model, it should be understood that the orientation terms such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" usually indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present utility model; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.
[0027] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the attached drawing is inverted, a device described as "above or over other devices or structures" will then be positioned "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.
[0028] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, so they cannot be understood as limiting the protection scope of the present utility model.
[0029] Referring jointly to Figures 1 to 5 As shown, according to an embodiment of the present utility model, a housing is provided, including: a housing body 1 and a swinging blade 2. A ventilation opening 3 is formed on the housing body 1. The swinging blade 2 is rotatably connected to the housing body 1. The swinging blade 2 is used to open or close the ventilation opening 3. The swinging blade 2 has a drainage portion 21, and along the width direction of the swinging blade 2, the drainage portion 21 gradually narrows.
[0030] In this technical solution, by improving the swinging blade 2 on the housing, the swinging blade 2 has a drainage portion, and along the width direction of the swinging blade 2, the drainage portion 21 gradually narrows. Therefore, when rainwater hits the swinging blade 2, water droplets will converge to the narrowest part of the drainage portion 21 under the action of gravity, and then gather and fall, so that the water droplets 5 will not contact the swinging blade 2 for a long time, thus significantly alleviating the corrosion of the cross-section of the swinging blade 2 by water and extending the service life of the swinging blade 2.
[0031] Referring to Figure 1 As shown, after the drainage portion 21 gradually narrows, a sharp corner is formed, which makes the water converging to the narrowest part of the drainage portion 21 easier to drip, and the water droplets stay on the swinging blade 2 for a shorter time.
[0032] Referring to Figure 1 As shown, the drainage portion 21 has a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface are joined to form a sharp corner. The first inclined surface extends from one side edge of the swinging blade 2 towards the tip of the sharp corner, and the second inclined surface extends from the other side edge of the swinging blade 2 towards the tip of the sharp corner.
[0033] In this embodiment, the first inclined surface and the second inclined surface are arranged such that the water droplets 5 on the swinging blade 2 can converge at least from the left and right sides towards the tip of the sharp corner, thereby accelerating the speed at which the water droplets 5 converge at the sharp corner.
[0034] Refer to Figure 3 As shown, the included angle formed between the first inclined surface and the second inclined surface is e, where 150° ≤ e ≤ 170°. This angle not only facilitates the water droplets 5 to flow to the tip of the sharp corner and converge and fall, but also ensures that the overall width b of the swinging blade 2 is not too wide to prevent the water droplets 5 from entering the interior of the housing through the ventilation opening 3.
[0035] Combined with reference to Figure 1 、 Figure 3 and Figure 5 As shown, the swinging blade 2 further has a main body portion 22. The upper side of the main body portion 22 is rotatably connected to the housing body 1. The drainage portion 21 is located below the main body portion 22. The shape and size of the ventilation opening 3 match the shape and size of the swinging blade 2.
[0036] In this technical solution, the main body portion 22 of the swinging blade 2 is equivalent to the shape of the original blade 4 in the prior art, and the drainage portion 21 is additionally added. That is, the swinging blade 2 in this application is larger than the blade 4 in the prior art. Therefore, when the shape and size of the ventilation opening 3 in this application match the shape and size of the swinging blade 2, it is equivalent to an enlargement treatment of the ventilation opening 3, so the air flow rate at the ventilation opening 3 increases and the overall heat dissipation efficiency is improved. After testing, the area of the ventilation opening 3 has increased by 10% - 20%, and thus the heat dissipation efficiency has increased by 10% - 20%. It should be noted that when the swinging blade 2 is in the state of closing the ventilation opening 3, viewed from the front, the main body portion 22 of the swinging blade 2 presents a rectangular shape, and the drainage portion 21 of the swinging blade 2 presents a triangular shape.
[0037] As a specific implementation manner, the main body portion 22 is of a cuboid structure. The width of the main body portion 22 is c, and the maximum width of the swinging blade 2 is b, where 1 / 2 ≤ (c / b) < 2 / 3. When the ratio between the width of the main body portion 22 and the maximum width of the swinging blade 2 satisfies this condition, it indicates that the main body portion 22 occupies a relatively large area of the swinging blade 2. Then, when the swinging blade 2 is in the state of opening the ventilation opening 3, it can ensure that the swinging blade 2 forms an effective oblique blockage of the ventilation opening 3 to prevent rainwater from entering. Among them, the length of the swinging blade 2 is a, where 100 mm ≤ a ≤ 120 mm, 10 mm ≤ b ≤ 15 mm, and 5 mm ≤ c ≤ 10 mm.
[0038] Combined with reference to Figure 4 and Figure 5As shown, when the swing blade 2 is in the state of opening the ventilation opening 3, the angle of rotation of the swing blade 2 relative to the housing body 1 is f, where 40° ≤ f ≤ 50°. This enables the swing blade 2 to block rainwater falling from above and obliquely above when in the state of opening the ventilation opening 3, so that while ventilating and dissipating heat, the swing blade 2 can also prevent rainwater from entering the interior of the housing.
[0039] Referring to Figure 2 and Figure 4 As shown, the number of ventilation openings 3 is multiple, and the ventilation openings 3 are arranged at intervals in sequence along the height direction of the housing body 1. The number of swing blades 2 is also multiple, and each swing blade 2 is rotatably connected to the housing body 1, and each swing blade 2 corresponds to each ventilation opening 3.
[0040] In this embodiment, when the number of ventilation openings 3 is multiple and the number of swing blades 2 is also set corresponding to the number of ventilation openings 3, the ventilation area can be increased, making the heat dissipation efficiency per unit time higher.
[0041] Referring to Figure 3 As shown, when each swing blade 2 is in the state of closing the ventilation opening 3, along the height direction of the housing body 1, the shortest distance between two adjacent swing blades 2 is d, where 2 mm ≤ d ≤ 5 mm.
[0042] In this technical solution, when the shortest distance d between two adjacent swing blades 2 satisfies the above conditions, the ventilation openings 3 and the swing blades 2 can be distributed on the housing body 1 with a reasonable density. Then, when each swing blade 2 is in the state of opening the ventilation opening 3, it can be ensured that the water droplets dripping from the upper swing blade 2 fall on the lower swing blade 2 and will not enter the interior of the housing from the ventilation opening 3. Preferably, each swing blade 2 is evenly distributed on the housing body 1.
[0043] Finally, it should be noted that the processing principle and process of the swing blade 2 of the present application are the same as those of the blade 4 in the prior art, and the swing blade 2 is also punched on the steel plate by using die cold stamping without redundant processes.
[0044] The present utility model also provides a heat dissipation device, including the aforementioned housing. The heat dissipation device of the present utility model can be an electrical box, an electrical control box, an air conditioning unit, etc.
[0045] It is easily understood by those skilled in the art that, on the premise of no conflict, the advantageous technical features of the above various methods can be freely combined and superimposed.
[0046] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. The above is only the preferred implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and variations can still be made, and these improvements and variations should also be regarded as within the protection scope of the present utility model.
