As shown in fig. 1 and 2, the utility model provides a control box, include:

a housing 101 having a cavity, the housing 101 may be made of a rigid material, such as a metal or alloy, or other types of materials. One end of the shell 101 is provided with a water inlet area, and the other end of the shell 101 is provided with a water outlet area;

the heat dissipation mechanism 102 is arranged in the cavity, the heat dissipation mechanism 102 comprises a peripheral wall 1021 and a plurality of heat dissipation fins 1022, the periphery of the peripheral wall 1021 is sealed, two ends of the peripheral wall 1021 are open, the plurality of heat dissipation fins 1022 are arranged in the peripheral wall 1021 at intervals, one end of the peripheral wall 1021 is provided with a first opening, the first opening is hermetically connected with the inner wall of one end of the shell 101 corresponding to the water inlet area, the other end of the peripheral wall 1021 is provided with a second opening, and the second opening is hermetically connected with the inner wall of the other end of the shell 101 corresponding to the water outlet area;

wherein, above-mentioned intake area is equipped with a plurality of drainage holes, and above-mentioned play water zone is equipped with a plurality of apopores, and above-mentioned a plurality of drainage holes, peripheral wall 1021 and above-mentioned a plurality of apopores communicate in proper order and form heat dissipation channel, and the aperture of above-mentioned drainage hole is less than the aperture of above-mentioned apopore.

Specifically, a mounting cavity adapted to provide a mounting space for the control board is formed between the inner sidewall of the housing 101 and the outer sidewall of the peripheral wall 1021.

Specifically, the plurality of water filtering holes, the peripheral wall 1021 and the plurality of water outlet holes are sequentially communicated to form a heat dissipation channel, which may be a curved channel, that is, one end of the housing 101 and the other end of the housing 101 may be any two ends of the housing 101.

It should be noted that the water inlet area and the water outlet area can be used for air to enter and exit, that is, the water inlet area and the water outlet area can be an air outlet area and an air inlet area respectively; above-mentioned a plurality of drainage holes can block most of water to get into above-mentioned heat dissipation channel when the water is met in the one end of control box, and all be less than the setting in the aperture of apopore based on the aperture of drainage hole, can only allow the less water droplet of volume to get into heat dissipation channel from drainage hole to make these water droplets flow from the apopore easily, take place the deposit at heat dissipation channel with effectively avoiding water, and then block up heat dissipation channel, the condition that influences the normal work of control box takes place. It is understood that the shapes of the water filtering holes and the water outlet holes are not limited herein, for example, the water filtering holes and the water outlet holes may be circular, polygonal, square, etc.; the aperture may be understood as the maximum distance of the shape in the hole, for example, a circular hole is a diameter, a square is a diagonal distance, and the like, but may be irregular, as long as the size of the water filtering hole is smaller than that of the water outlet hole.

In an application scenario of the present embodiment, the plurality of water filtering holes are formed at one end of the housing 101, and the plurality of water outlet holes are formed at the other end of the housing 101.

Specifically, as shown in fig. 1 and 2, the housing 101 includes a middle housing 1011, an upper cover 1012, and a lower cover 1013, the middle housing 1011 includes a first sub-housing 10111 and a second sub-housing 10112, the plurality of water filtering holes are formed by forming a hole in the upper cover 1012, the plurality of water filtering holes form a water inlet region, the plurality of water outlet holes are formed by forming a hole in the lower cover 1013, and the plurality of water outlet holes form a water outlet region.

It can be understood that the size of the water filtering holes cannot be too large, if the size of the water filtering holes is too large, the control box is easy to be greatly entered by water when meeting rainwater or splashing water, and the size of the water outlet holes cannot be too small, if the size of the water outlet holes is too small, water is easy to form a water film at the water outlet holes to block the water outlet holes, so that the phenomena that the water entering area has more water, the water discharging area discharges less water or even does not discharge water are caused, and the waterproof performance of the control box is further reduced; the aperture of the water filtering hole is set to be too small, which easily causes the air flow to flow normally, thereby affecting the heat dissipation, and especially under the condition, the fan is introduced to accelerate the air flow velocity so as to enhance the heat dissipation effect and easily generate great noise. Therefore, the aperture of the water filtering hole is not less than 0.5 mm and not more than 3 mm, and the aperture of the water outlet hole is not less than 3 mm.

Specifically, the aperture of the water filtering hole may be 0.5 mm, 1.5 mm, 2 mm, or 3 mm, and the aperture of the water outlet hole may be 3.1 mm, 3.5 mm, 5 mm, or 7 mm.

Specifically, as shown in fig. 3, the water filtering holes formed by opening the upper cover 1012 may be upper cover holes 10121, and a plurality of upper cover holes 10121 form a water inlet region; as shown in fig. 4, the outlet formed by the opening of the lower cover 1013 may be a lower cover hole 10131, and a plurality of the lower cover holes 10131 constitute a water outlet area.

In another application scenario of this embodiment, a waterproof net 103 is disposed at the water inlet area, and the waterproof net 103 may be made of stainless steel or plastic or other types of materials. The plurality of water filtering holes are formed in the waterproof net 103, a plurality of water inlet holes are formed in one end of the housing 101, the plurality of water inlet holes form a water inlet area, the diameter of each water inlet hole is larger than that of each water filtering hole, and the plurality of water outlet holes are formed in the other end of the housing 101.

Specifically, as shown in fig. 1 and 2, the housing 101 includes a middle housing 1011, an upper cover 1012 and a lower cover 1013, the middle housing 1011 includes a first sub-housing 10111 and a second sub-housing 10112, the waterproof net 103 is disposed at the water inlet region, the plurality of water inlet holes are formed by opening holes in the upper cover 1012, the plurality of water filter holes are formed by opening holes in the waterproof net 103, and the plurality of water outlet holes are formed by opening holes in the lower cover 1013.

Specifically, as shown in fig. 5, the waterproof net 103 is provided with a plurality of waterproof net meshes 1031, the water filtering holes may be the waterproof net meshes 1031, and the plurality of waterproof net meshes 1031 and the plurality of water inlet holes together form a water inlet area.

It should be noted that the structure of the waterproof net 103 needs to match with the arrangement structure of the plurality of water inlet holes in the water inlet area of the upper cover 1012; as shown in fig. 2, in order to facilitate the placement of the display screen, at least a portion of the upper cover 1012 is disposed in an inclined manner, the inclined portion of the upper cover 1012 is also correspondingly provided with a water inlet region formed by a plurality of water inlets, and the waterproof mesh 103 is also a bent structure corresponding to the arrangement structure of the plurality of water inlets of the water inlet region, so that when water enters the heat dissipation channel from the plurality of water filtering holes, the water can reach the plurality of water outlets and flow out of the heat dissipation channel by filtering water through the waterproof mesh 103, thereby enhancing the waterproof performance of the control box.

Further, the waterproof net 103 is provided inside the housing 101, and the waterproof net 103 may be provided outside the housing 101 if the appearance is not taken into consideration, and for example, the waterproof net 103 may be fixed inside or outside the housing by means of bonding, snap-fitting, or fixing with a fixing member.

Further, the pore diameter of the water filtration pore is not less than 0.5 mm and not more than 3 mm, and may be, for example, 0.5 mm, 1.5 mm, 2 mm or 3 mm. The aperture of the water outlet is larger than 3 mm, and the aperture of the water inlet is larger than 3 mm, for example, the apertures may be 3.1 mm, 3.5 mm, 5 mm or 7 mm. It can be understood that through the above design, when the control box is exposed to rain or water splashing, water can enter from the water inlet hole first, and then the water entering is reduced due to the proper blocking function of the water filtering hole. Since the difficulty and cost of directly forming the plurality of water filtering holes having the pore diameters of 0.5 mm or more and 3 mm or less on the upper cover 1012 are extremely high, a good waterproof effect can be achieved and the production and manufacturing costs can be greatly reduced by introducing a waterproof net having the pore diameters of 0.5 mm or more and 3 mm or less.

It can be understood that the aperture of the water inlet hole and the aperture of the water outlet hole can be the same or different, but the aperture of the water inlet hole and the aperture of the water outlet hole are both required to be larger than the aperture of the water filtering hole.

Further, the housing 101 includes a middle housing 1011, an upper cover 1012 and a lower cover 1013, the upper cover 1012 is connected to the top end of the middle housing 1011, the lower cover 1013 is connected to the bottom end of the middle housing 1011, and the middle housing 1011, the upper cover 1012 and the lower cover 1013 enclose the above-mentioned housing; the water outlet area is arranged on the lower cover 1013, and the water inlet area is arranged on the upper cover 1012; the inner wall of the upper cover 1012 is provided with a first sealing structure, the heat dissipation mechanism 102 is provided with a second sealing structure matched with the first sealing structure, and the waterproof net 103 is fixed between the first sealing structure and the second sealing structure. It will be appreciated that the first and second sealing structures may be interfitting stepped or staggered structures, or the like.

Optionally, the heat dissipation mechanism 102 further includes:

as shown in fig. 2, 6 and 7, the first wind scooper 1023 has a wide cavity and a narrow cavity inside, which are communicated with each other, the port 10232 of the narrow cavity of the first wind scooper 1023 is connected with the first opening in a sealing manner, and the port 10231 of the wide cavity of the first wind scooper 1023 is connected with the inner wall of one end of the housing 101 in a sealing manner corresponding to the water inlet area; the second air guiding cover 1024, as shown in fig. 2, 8 and 9, has a wide cavity and a narrow cavity therein, which are communicated with each other, the port 10241 of the narrow cavity of the second air guiding cover 1024 is connected with the second opening in a sealing manner, and the port 10242 of the wide cavity of the second air guiding cover 1024 is connected with the inner wall of the other end of the casing 101 in a sealing manner corresponding to the water outlet area; the plurality of water filtering holes, the first wind scooper 1023, the peripheral wall 1021, the second wind scooper 1024 and the plurality of water outlet holes are communicated in sequence to form a heat dissipation channel.

Further, as shown in fig. 2, the heat dissipation mechanism 102 further includes:

and the fan 1025 is arranged between the second air guiding cover 1024 and the end surface of the water outlet area, and the total area of the plurality of water outlet holes is larger than half of the area of the fan 1025, so that water can flow out of the plurality of water outlet holes more easily, and cold air outside the heat dissipation channel can flow in from the plurality of water outlet holes more easily.

In particular, fan 1025 may be a silent fan or other type of fan.

Specifically, the fan 1025 is installed between the second wind scooper 1024 and the plurality of water outlet holes in the heat dissipation channel.

Further, as shown in fig. 10 and 11, a distance D between an end surface of the fan 1025 closest to the second opening and the second opening, and a diameter dimension of a rotation shaft of the fan 1025 are D, and the dimension of D is 1 to 1.5 times the dimension of D.

Specifically, the size of D may be 1 time, 1.25 times, or 1.5 times the size of D.

Note that, if D is too small, noise generated between the fan 1025 and the peripheral wall 1021 may be large; if D is too large, the heat dissipation capacity of the control box is smaller; when the size of D is 1-1.5 times of the size of D, the noise is not too large, and the heat dissipation capacity of the control box is strong.

Furthermore, the farthest point of the edge of the fan 1025 from the axis of the fan 1025 is the point M, and a gap is formed between the inner wall of the second air guiding cover 1024, which forms the corresponding cover body portion of the wide cavity, and the point M.

Specifically, the fan 1025 includes a motor, fan blades, and a fixing frame, and the area of the fan surface may be the area of the smallest circle where the rotation area of the fan blades of the fan 1025 is located, or the area of the fan surface end surface of the fan 1025, as shown in fig. 11, the fan surface end surface may be an end surface of the fan 1025 that includes the fan blades and the fixing frame, and the fixing frame may be in any shape. It can be understood that, when the fan 1025 works, air can enter from the water outlet hole of the water outlet area, then pass through the gaps of the plurality of heat dissipation fins 1022, and finally exit from the water filtering holes of the water inlet area (or first enter the water filtering holes and then exit from the water inlet holes), that is, the air flow direction of the fan 1025 is exactly opposite to the water discharging direction of the control box, for example, the fan 1025 blows from bottom to top to dissipate heat while water is discharged from top to bottom, although in other embodiments, the fan may be disposed at the top, and the air flow direction of the fan 1025 is exactly the same as the water discharging direction of the control box.
