Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of ventilation and heat dissipation of electronic equipment, and in particular to a rainproof ventilation device. Background Art

[0002] Most electronic equipment use fans installed inside them to dissipate heat through open forced convection. This cooling method requires ventilation windows to be set on the electronic equipment to allow internal airflow and external air to exchange heat. Currently, most electronic equipment use shutters to achieve rainproof ventilation, and some electronic equipment use angled grid shutters. However, existing shutters completely close the blades to prevent rain, and air cannot enter while preventing rain, so the internal components of the electronic equipment cannot dissipate heat. Although the angled grid shutters can prevent rain, they seriously reduce the air intake volume of the fan during forced convection cooling, resulting in poor heat dissipation efficiency.

[0003] The application number is 201610189783.1, and the name is an adjustable hole-type rainproof ventilation window, which includes two layers of parallel ventilation plates and a sliding mechanism. The ventilation plates can slide along the sliding mechanism. The ventilation plates are provided with a plurality of ventilation holes. The ventilation holes on adjacent ventilation plates are staggered. The purpose of rainproof ventilation is achieved by adjusting the spacing between the ventilation plates. Although the ventilation window has a sliding mechanism added to achieve the purpose of rainproof ventilation, it requires human intervention, so the purpose of automatic rainproof ventilation cannot be achieved. Therefore, it is necessary to improve one or more problems existing in the above-mentioned related technical solutions.

[0004] It should be noted that this section is intended to provide a background or context to embodiments of the invention recited in the claims. No admission is made that the description herein is prior art by inclusion in this section. Summary of the invention

[0032] In this exemplary embodiment, a rainproof and ventilation device is first provided. Referring to Figure 1 as shown, the device may include a cover plate 100 and a rain shield 200.

[0033] The cover plate 100 includes a recessed portion 101, and a ventilation hole 1012 is provided on the bottom surface of the recessed portion 101; the rain shield 200 is installed on the cover plate 100, is adapted to the recessed portion 101, and together with the recessed portion 101 forms a cavity, and a plurality of first air inlets 201 are provided on the rain shield 200, and the positions of the first air inlets 201 are arranged offset from the position of the ventilation hole 1012; wherein, a notch 202 is provided below the rain shield 200, and the notch 202 is used to form a first opening 2021 with the cover plate 100.

[0034] According to the rainproof and ventilation device provided by the present invention, through the combined use of the recessed portion 101 on the cover plate 100 and the rain shield 200, when rainwater mixed with air enters the cavity formed by the recessed portion 101 and the rain shield 200 from the first air inlets 201 on the rain shield 200, the rainwater falls due to the action of gravity and is discharged from the first opening 2021, and the first air inlets 201 and the ventilation hole 1012 are arranged offset, to a certain extent, preventing rainwater from directly entering the ventilation hole 1012, thereby achieving the purpose of rainproof and ventilation, and the device does not require manual intervention, saving labor costs.

[0035] Next, Figures 1 to 7 a more detailed description will be given of each part of the above rainproof and ventilation device in this exemplary embodiment.

[0036] In one embodiment, as Figure 1As shown, a recessed portion 101 is provided on the lower side of the cover 100, and the recessed portion 101 is used in conjunction with a rain cover 200 of a matching shape, and the recessed portion 101 can form a cavity with the rain cover 200, and a ventilation hole 1012 is provided on the bottom surface of the recessed portion 101, and the ventilation hole 1012 is used as an air inlet for heat dissipation of electronic devices; and a plurality of first air inlets 201 are provided on the rain cover 200. In order to prevent the gas mixed with rainwater entering the cavity from the first air inlet 201 from directly entering the ventilation hole 1012, the opening positions of the first air inlet 201 and the ventilation hole 1012 are staggered. When rainwater enters the cavity, it falls due to gravity, and is prevented from entering the ventilation hole 1012 with the air flow. In one example, the cross-section of the recessed portion 101 is trapezoidal, and the inclined surface 102 is located below the recessed portion 101, so that the rainwater entering the cavity can be discharged. Specifically, as Figure 3 , 4 As shown, the recessed portion 101 is actually a trapezoidal groove 203 opened on the cover plate 100, and the inclined surface 102 is located below the recessed portion 101. The falling rainwater will flow out along the inclined surface 102, which can further accelerate the speed of rainwater flowing out.

[0037] In addition, if Figure 2 As shown, a notch 202 is provided at the bottom of the rain cover 200. The notch 202 can be set to a rectangular shape, but there is no limitation. The notch 202 can form a first opening 2021 between the cover plate 100, and the first opening 2021 can be used as an air inlet to increase the air intake at the ventilation hole 1012.

[0038] In one embodiment, Figure 4 As shown, the front side of the cover plate 100 includes a U-shaped groove 103, the U-shaped groove 103 is connected to the bottom surface of the cover plate 100, and the recessed portion 101 is arranged in the U-shaped groove 103. Specifically, for the convenience of installation, a U-shaped groove 103 is pre-arranged at the position where the recessed portion 101 is arranged, and the U-shaped groove 103 is connected to the ground of the cover plate 100, so as to facilitate the outflow of rainwater flowing out of the cavity; and a plurality of mounting holes 1031 are arranged at the edge of the recessed portion 101, that is, at the circumferential position of the U-shaped groove 103, for fastening the wind shield to the position of the U-shaped groove 103 on the cover plate 100.

[0039] In one embodiment, a groove 203 is provided on one side of the rain cover 200 facing the cavity, and the groove 203 is connected to the lower surface of the rain cover 200, and a second opening 203 is formed between the lower part of the rain cover 200 and the U-shaped groove 103. Figure 7As shown, a groove 203 is provided on one side of the rain shield 200 facing the cavity, and this groove 203 communicates with the lower surface of the rain shield 200. Moreover, a second opening 203 can be formed between the lower part of a part of the rain shield 200 (excluding the notch 202 part) and the U-shaped groove 103. In one example, the second opening 203 is the third air inlet; the second opening 203 is the second drain. This second opening 203 can not only serve as an air inlet to increase the air volume entering the ventilation hole 1012, but also when rainwater flows down from the inclined surface 102 of the recessed part 101, it can be discharged from the second drain, so as to increase the rainwater discharge speed to a certain extent.

[0040] In one embodiment, the first opening 2021 is the second air inlet; the first opening 2021 is the first drain. Specifically, as Figure 2 shown, the first opening 2021 is formed between the notch 202 under the rain shield 200 and the cover plate 100. This first opening 2021 can serve as the second air inlet to provide air volume for the ventilation hole 1012, and can also serve as the first drain. When rainwater enters the cavity through the first air inlet 201 with the air and then falls due to gravity, it can be discharged from this first drain.

[0041] In one embodiment, a sealing groove 104 is provided circumferentially on the back of the cover plate 100 for setting the sealing ring 400 to ensure the sealing between the cover plate 100 and the electronic device. Specifically, the back of the cover plate 100 is used to connect with the electronic device. To prevent rainwater and the like from entering through the connection between the cover plate 100 and the electronic device, a sealing groove 104 is provided on the back of the cover plate 100, and a suitable sealing ring 400 is provided in this sealing groove 104, so as to ensure the sealing between the cover plate 100 and the electronic device.

[0042] In one embodiment, the outside of the ventilation hole 1012 is used to connect the fan 500, and this fan 500 is located at the back of the cover plate 100. Specifically, as Figure 5 shown, the fan 500 is arranged at the ventilation hole 1012 on the back of the cover plate 100 for conveying air flow into the electronic device. When the fan 500 works, the air flow enters the cavity formed by the back groove 203 of the rain shield 200 and the recessed part 101 of the cover plate 100 from the first air inlet 201, the second air inlet and the third air inlet, and then enters the interior of the electronic device through the protective net 300, the circular ventilation hole 1012 on the bottom surface of the recessed part 101, and the fan 500. The rainwater flows out through the first drain and the second drain under the action of gravity.

[0043] In one embodiment, the device further includes a protective net 300, and this protective net 300 is installed at the ventilation hole 1012 through the mounting hole 1013, and this protective net 300 is located inside the cavity. Specifically, asFigure 1 As shown, the protective net 300 is installed at the position of the ventilation hole 1012 in the cavity, and the protective net 300 can prevent insects and the like from entering.

[0044] In one embodiment, the number of the first air inlets 201 is between 3 and 6. Specifically, the number of the first air inlets 201 can be set according to the area of the ventilation hole 1012 and the area of the first air inlet 201, and does not affect the normal air intake of the ventilation hole 1012, and the specific number is not limited.

[0045] In one embodiment, the cover plate 100 is provided with a plurality of lightening grooves 105 for reducing the weight of the cover plate 100; the rain cover 200 is provided with a plurality of lightening grooves 204 for reducing the weight of the rain cover 200. Specifically, Figure 5 , 7 As shown, the cover plate 100 and the rain cover 200 are both provided with a plurality of lightening grooves for reducing the weight of the entire rainproof and ventilating device.

[0046] According to the rainproof and ventilation device provided by the present invention, through the coordinated use of the recessed portion 101 on the cover plate 100 and the rain cover 200, when rainwater mixed with air enters the cavity formed by the recessed portion 101 and the rain cover 200 from the first air inlet 201 on the rain cover 200, the rainwater falls due to the action of gravity and is discharged from the first opening 2021, and the first air inlet 201 and the ventilation hole 1012 are staggered, which to a certain extent prevents rainwater from directly entering the ventilation hole 1012, thereby achieving the purpose of rainproof and ventilation, and the device does not require manual intervention, saving labor costs.
