For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0039] Waterproof and heat dissipation of power distribution equipment is extremely important. Poor waterproofing can easily lead to short circuits in the power distribution equipment, making it impossible for the power distribution equipment to supply power normally, and may even damage the components inside the power distribution equipment. In addition, moisture will accelerate the corrosion of metal parts, such as metal casings, brackets, bolts, etc. in the power distribution equipment. Good waterproofing measures can effectively prevent moisture from contacting metal parts, reduce the occurrence of corrosion, and thus extend the service life of the equipment. Even when the staff touches the water-infiltrated power distribution equipment, electric shock accidents are likely to occur. If the heat dissipation is not good, the heat generated by the power distribution equipment during operation will accumulate, which will increase the temperature of the equipment. Excessive temperature will accelerate the aging of the insulation material, reduce its insulation performance, increase the risk of equipment failure, affect the performance stability of the power distribution equipment, affect the power supply quality, and easily shorten the service life of the power distribution equipment. In serious cases, it may even cause a fire.

[0040] Therefore, it is very important to improve the waterproof and heat dissipation capabilities of the power distribution equipment. However, it is difficult for the power distribution equipment in the related art to have both good waterproof and heat dissipation capabilities.

[0041] Based on this, the present application provides a waterproof heat dissipation device and a power distribution system, which can have both waterproof and heat dissipation effects on the power distribution equipment, so that the power distribution equipment can have a certain degree of waterproofness, can resist damage caused by waterlogging, and at the same time have a better heat dissipation effect.

[0042] See also Figure 1 and Figure 2 As shown, Figure 1 Schematic diagram of the structure of a waterproof heat dissipation device 10 in one embodiment of the present application. Figure 2 for Figure 1 A schematic diagram of the structure of the waterproof heat dissipation assembly 200 in the illustrated embodiment. The waterproof heat dissipation device 10 provided in the present application includes a housing 100 and a waterproof heat dissipation assembly 200. The housing 100 defines a housing cavity, which is used to accommodate the power distribution equipment. That is, the power distribution equipment is placed inside the housing 100, and the housing 100 is used to protect the power distribution equipment inside.

[0043] Along the height direction of the containment shell 100, the waterproof heat dissipation component 200 is arranged at the top of the containment shell 100 and is located outside the containment shell 100. The waterproof heat dissipation component 200 includes a shell body 210 and a waterproof component 220. The shell body 210 defines a heat dissipation channel extending along the height direction of the containment shell 100. The heat dissipation channel is connected to the containment cavity, and the waterproof component 220 is arranged in the heat dissipation channel.

[0044] It can be understood that when the power distribution equipment is running, the heat generated by the power distribution equipment will flow upward. The waterproof heat dissipation component 200 is arranged on the top of the housing shell 100, which can make use of the density difference and thermal pressure difference of the air to make the heat flow upward and dissipate the heat through the heat dissipation channel. At the same time, the waterproof component 220 is arranged to waterproof the heat dissipation channel. In this way, the heat dissipation channel can dissipate heat while preventing rainwater from entering the housing cavity from the heat dissipation channel to corrode the power distribution equipment, reducing the risk of water flow or rainwater soaking in the external environment damaging the power distribution equipment, and facilitating waterproof protection of the power distribution equipment. Furthermore, the waterproof heat dissipation device 10 of the present application has a better waterproof sealing effect while also having a better heat dissipation effect, and with the help of a clever design, its structure can be very simple and the manufacturing cost can be reduced.

[0045] In some embodiments, in combination with Figure 3 and Figure 4 As shown, Figure 3 for Figure 2 The waterproof heat dissipation assembly 200 shown is a structural schematic diagram in which part of the wall panel 230 is omitted. Figure 4 for Figure 2 The waterproof heat dissipation assembly 200 shown is a structural diagram without all the wall panels 230. The waterproof assembly 220 has a plurality of rain gutters 221, which are arranged in the heat dissipation channel extending along the first direction F1, and the notches of the rain gutters 221 are arranged toward the side of the heat dissipation channel away from the containing shell 100. In other words, the notches of the rain gutters 221 are arranged upward, and when rain or water flows down, the water flow can be caught by the rain gutters 221, and it can be understood that the water flow that the rain gutters 221 can connect to plays a guiding role, so that the water flow flows out to both sides of the extending direction of the rain gutters 221, thereby reducing the risk of water flow entering the containing cavity through the heat dissipation channel.

[0046] The projections of the multiple rain gutters 221 on the reference plane in the vertical direction of the height of the housing 100 are located within the range of the orthographic projection of the housing body 210 on the reference plane in the vertical direction of the height of the housing 100. The first direction F1 and the height direction of the housing 100 intersect with each other. It can be understood that the multiple rain gutters 221 can cover all lateral locations of the heat dissipation channel, so that water flow or rainwater can be caught by the rain gutters 221 no matter where it flows to the heat dissipation channel in the horizontal direction, further reducing the risk of water ingress into the housing cavity.

[0047] In this embodiment, the first direction F1 is not limited to being perpendicular to the height direction of the containing shell 100, that is, the rain gutter 221 can be relatively inclined along the first direction F1, so that rainwater connected to the rain gutter 221 can flow along one end of the first direction F1 under the action of gravity, which is beneficial to improving the drainage efficiency of the rain gutter 221.

[0048] In some embodiments, continue to refer to Figure 3 and Figure 4 As shown, a plurality of rain grooves 221 form a plurality of groove groups, and the plurality of groove groups are spaced apart from each other along the height direction of the containment shell 100, and the groove groups include a plurality of rain grooves 221 spaced apart along the second direction F2, and the rain grooves 221 of two adjacent groove groups are staggered along the second direction F2. Among them, the first direction F1, the second direction F2 and the height direction of the containment shell 100 intersect with each other. In other words, a plurality of rain grooves 221 form a multi-layer structure along the height direction of the containment shell 100, and each layer has a plurality of rain grooves 221, so that a multi-layer protection is formed to further improve the waterproof effect. At the same time, the rain grooves 221 in each layer are spaced apart, and the two adjacent layers of rain grooves 221 are also spaced apart, so that there are intervals between the plurality of rain grooves 221, and the use of the intervals can effectively improve the heat dissipation efficiency. That is, the present application can have a better heat dissipation effect through the heat dissipation channel through the above-mentioned waterproof heat dissipation component 200, and can also have a better waterproof effect. It can be understood that when multiple layers or multiple rain gutters 221 receive rainwater or water flow, they are cooled by the rainwater or water flow, which is also beneficial to improving the heat conduction effect in the accommodating cavity, improving the cooling effect of the accommodating cavity, and further facilitating further heat dissipation of the power distribution equipment.

[0049] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, the waterproof assembly 220 also includes a plurality of waterproof baffles 222. A waterproof baffle 222 is provided between two adjacent rain gutters 221 of the same groove group. The waterproof baffle 222 may be a baffle structure. In the case of oblique rain, there is a risk that rain leaks from between two adjacent rain gutters 221 and enters the receiving cavity. The waterproof baffle 222 provided between two adjacent rain gutters 221 can effectively block oblique rain, and combined with the structural design that the rain gutters 221 of two adjacent groove groups are alternately provided along the second direction F2, the rain blocked by the water baffle can enter the rain gutters 221 of another groove group, as shown in FIG. Figure 4 As shown, the waterproof blocking member 222 can be opposite to the other rain troughs 221 below, so that the rainwater blocked by it enters the rain trough 221 opposite to it and is discharged smoothly. In this way, the risk of rainwater drifting obliquely into the receiving cavity is reduced, and the waterproof effect is further improved. In particular, when the waterproof heat dissipation device 10 of the present application is used in an outdoor environment and is subjected to severe weather such as strong winds and heavy rains, the waterproof blocking member 222 can reduce the impact of rainwater on the waterproof component 220 and improve the waterproof performance.

[0050] In this embodiment, the waterproof baffle 222 can be set only on the topmost slot group or the slot group farthest away from the containment shell 100 along the height direction of the containment shell 100. The waterproof baffle 222 can also be set in any layer or at least two layers of the slot groups. It is not limited to setting the waterproof baffle 222 in each layer of the slot groups. The specific setting can be made according to actual needs. This is beneficial to saving materials and reducing costs.

[0051] In some embodiments, see Figure 2-Figure 4 ,as well as Figure 5 As shown, Figure 5 for Figure 2 The waterproof heat dissipation assembly 200 shown in the figure omits the structural diagram of the base 211 and the telescopic part 214. The shell body 210 includes a base 211, a mounting part 212 and a plurality of telescopic parts 214, the mounting part 212 is used to install the rain gutter 221, and the base 211 is connected to the top of the housing 100. The plurality of telescopic parts 214 are sequentially arranged between the mounting part 212 and the base 211 along the height direction of the housing 100, and along the height direction of the housing 100, one of the two adjacent telescopic parts 214 is telescopically arranged relative to the other of the two adjacent telescopic parts 214 along the height direction of the housing 100. The mounting part 212 can be stacked to a desired height by using a plurality of telescopic parts 214 according to actual needs. After the heat dissipation channel is telescopically stacked to a desired height, it can effectively prevent outdoor wind and rain from splashing into the interior of the heat dissipation channel, which is conducive to further improving the waterproof effect. The setting of the telescopic part 214 can not only adjust the installation part 212 and the rain gutter 221 to the required height, but also help to improve the transportation convenience, reduce the assembly efficiency and transportation cost of the waterproof heat dissipation device 10, and increase the application scenarios of the waterproof heat dissipation device 10.

[0052] For example, if a device is installed with a waterproof heat dissipation structure in the related technology, due to the high height of the whole device and the transportation height restrictions on some roads and bridges, when transporting this type of equipment, it is often necessary to disassemble the waterproof heat dissipation structure separately for shipment, and then reassemble it on site after transporting it to the site. This not only increases the equipment transportation cost, but also increases the assembly cost of the equipment on site. If the device adopts the waterproof heat dissipation device 10 with a telescopic portion 214 of the present application, the device can be fully assembled in advance in the factory, and the waterproof heat dissipation structure can be shortened to a suitable height before transportation, and then shipped for transportation. After the device is transported to the site, the waterproof heat dissipation structure is stretched to the required height, and then locked by the screw and locking nut 250 to maintain the state. In this way, the equipment transportation and installation costs can be effectively reduced.

[0053] In some embodiments, the waterproof heat dissipation device 10 also includes a locking screw 240 and a locking nut 250 disposed on the base 211. The locking screw 240 extends along the height direction of the containing shell 100 and is passed through the mounting portion 212. The locking nut 250 is sleeved on the locking screw 240 to cooperate with the locking screw 240 to lock the mounting portion 212 at a preset position of the locking screw 240, so that the mounting portion 212 can be fixed at a suitable height, so that the waterproof heat dissipation device 10 maintains its state and reduces its risk of slipping.

[0054] In some embodiments, the base 211 can be configured as a mounting flange structure so that the waterproof heat dissipation assembly 200 can be mounted on the housing 100 through the base 211, thereby facilitating installation convenience.

[0055] In some embodiments, Figure 3 and Figure 4 As shown, the mounting portion 212 includes two baffles 213 spaced apart along the first direction F1, the rain gutter 221 is disposed between the two baffles 213, and a plurality of water outlets are disposed on the baffles 213, the rain gutter 221 is disposed at the water outlets or the rain gutter 221 is connected to the water outlets. It can be understood that the provision of the baffles 213 is conducive to further reducing the risk of rainwater drifting into the heat dissipation channel or the interior of the accommodation cavity from the side, and the water outlet is provided so that the rainwater received in the rain gutter 221 can flow out smoothly from the water outlet without affecting the outflow of rainwater in the rain gutter 221.

[0056] In this embodiment, the mounting portion 212 also includes two additional water-blocking plates 213 spaced apart along the second direction F2, and the two water-blocking plates 213 spaced apart along the second direction F2 are also disposed on both sides of the plurality of rain gutters 221, so as to reduce the risk of rainwater drifting into the heat dissipation channel, i.e., the interior of the container, from both sides along the second direction F2, thereby further reducing the risk of water ingress.

[0057] In some embodiments, in conjunction with Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the waterproof heat dissipation device 10 also includes a wall plate 230, which is arranged around an axis parallel to the height direction of the housing shell 100 on the peripheral side of the mounting portion 212 and is spaced apart from the mounting portion 212. It can be understood that by arranging the wall plate 230 on the peripheral side of the mounting portion 212, rainwater can be further shielded by the wall plate 230, reducing the oblique drift of rainwater into the rain gutter 221, thereby facilitating the rain gutter 221 to discharge the received rainwater outward, thereby improving the drainage effect. This is further conducive to the drainage of the rain gutter 221, reducing the risk of water splashing into the housing cavity due to water accumulation in the rain gutter 221, thereby improving the waterproof effect. It can also be understood that the waterproof heat dissipation assembly 200 of the present application can also achieve windproof and dustproof effects through the waterproof assembly 220, the baffle 213 and the wall plate 230.

[0058] In some embodiments, in combination Figure 3 , Figure 4 and Figure 6 As shown, the groove structure of the rain gutter 221 can be in the shape of an inverted triangle, or in other words, can be set as a "V"-shaped structure for receiving rainwater. The angle of the two side walls of the "V"-shaped structure and the size of the two side walls can be designed according to actual needs, and the rain gutter 221 can also be set as other groove-shaped structures according to actual needs, and no excessive settings are made here.

[0059] In some embodiments, the housing 100 is provided with a bottom air inlet and a top air outlet at opposite ends along its height direction, the bottom air inlet is connected to the housing cavity and the external environment, the waterproof heat dissipation assembly 200 is provided at the top air outlet, and the heat dissipation channel is connected to the housing cavity through the top air outlet. Thus, the density difference and thermal pressure difference of the air can be used to discharge hot air from the top air outlet and to inhale cold air from the bottom air inlet, so as to realize air flow and reduce the temperature of the heat source in the housing cavity.

[0060] In some embodiments, see Figure 1 As shown, the waterproof heat dissipation device 10 further includes a protective member 260, which is disposed on the side of the plurality of rain grooves 221 away from the housing 100. The protective member 260 is used to prevent foreign matter from entering the housing cavity, and prevent foreign matter from entering the rain grooves 221 and the heat dissipation channel, thereby further protecting the power distribution equipment in the housing cavity. In this embodiment, the protective member 260 can be set as a mesh structure, which is conducive to improving the protection level to prevent foreign matter from entering the interior of the housing cavity.

[0061] In some embodiments, see Figure 1As shown, the waterproof heat dissipation device 10 also includes a lifting component 270, which is arranged on the installation portion 212 and is located on the side of the installation portion 212 away from the containing shell 100. The lifting component 270 facilitates the lifting and transportation of the waterproof heat dissipation device 10 or the waterproof heat dissipation assembly 200, thereby improving the transportation convenience.

[0062] The waterproof principle of the waterproof heat dissipation device 10 of the present application is as follows: multiple rain gutters 221 are designed in a multi-layer staggered arrangement. The rain gutters 221 of the first layer of the groove group directly receive rainwater, and the received rainwater will flow from both ends of the rain gutters 221 to the outside of the heat dissipation channel. The rain gutters 221 of the second layer of the groove group will also directly receive rainwater, but due to the staggered shielding of the first layer of the groove group, the rainwater received by the rain gutters 221 of the second layer of the groove group will be slightly less than the rainwater received by the rain gutters 221 of the first layer of the groove group, and the rainwater received by the rain gutters 221 of the second layer of the groove group will also flow from both ends of the rain gutters 221 to the outside of the heat dissipation channel. By analogy, the rain gutters 221 of the groove group that are closer to the accommodating cavity will receive less and less rainwater. In this way, through this structure and method, a waterproof effect is ultimately achieved.

[0063] The heat dissipation principle of the waterproof heat dissipation device 10 of the present application is as follows: the multiple rain grooves 221 are designed to be arranged in a multi-layer staggered manner. In the horizontal direction, in the rain grooves 221 of the same layer of groove group, a ventilation gap of a certain distance is set between every two rain grooves 221, and in the vertical direction, a ventilation gap of a certain distance is also set between the upper and lower layers of rain grooves 221. The heat brought up from the heat dissipation channel can be dissipated into the air through the above-set ventilation gaps, and finally achieve a heat dissipation effect.

[0064] According to another aspect of the present application, a power distribution system is also provided, including a power distribution device and the waterproof heat dissipation device 10 described in any of the above embodiments, wherein the power distribution device is arranged in the waterproof heat dissipation device 10. The power distribution device is a key device for distributing and controlling electric energy in a power system, such as a circuit breaker, a fuse, a relay, and a transformer, etc., and can be designed according to actual power distribution requirements, and no excessive restrictions are made here.

[0065] The waterproof heat dissipation device 10 and the power distribution system of the present application can utilize the density difference and thermal pressure difference of the air to make the heat flow upward and dissipate the heat through the heat dissipation channel. At the same time, the heat dissipation channel is waterproofed by utilizing multiple rain gutters 221 arranged in a staggered manner, so that the heat dissipation channel can dissipate heat while preventing rainwater from entering the accommodating cavity from the heat dissipation channel to corrode the power distribution equipment, thereby reducing the risk of water flow or rainwater soaking in the external environment damaging the power distribution equipment, and facilitating waterproof protection of the power distribution equipment. Furthermore, the waterproof heat dissipation device 10 of the present application has a better waterproof sealing effect while also having a better heat dissipation effect, and with the help of a clever design, the structure can be very simple and the manufacturing cost can be reduced.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
