Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] This utility model provides a heat dissipation device and a box-type substation with the heat dissipation device. Similar to the prior art, the box-type substation is used to step down high voltage electricity to low voltage electricity and distribute it to users. The box-type substation is equipped with lines and equipment. During operation, the lines and equipment will generate heat and accumulate inside the box-type transformer. In order to avoid heat accumulation and thus affect the normal operation of the lines and equipment, multiple heat dissipation devices need to be installed on the box-type transformer.

[0026] Currently, heat dissipation devices are typically semi-enclosed. Impurities from the external environment can pass through the semi-enclosed area of ​​the heat dissipation device naturally or with airflow, eventually entering the transformer. These impurities accumulate on the lines and equipment, thus affecting their heat dissipation efficiency. Therefore, to ensure the effective operation of the lines and equipment, the heat dissipation device must, while ensuring heat dissipation, prevent external impurities from entering the prefabricated substation through it.

[0027] The following detailed description of the overall structure, working principle, and technical effects of the heat dissipation device, box-type substation, and box-type energy storage integrated unit provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0028] Example 1: Please refer to Figure 1 The heat dissipation device provided in this embodiment includes a housing 100. The housing 100 includes an inner housing 110 and an outer housing 120 that are sequentially sleeved from the inside to the outside along a first direction. The side of the inner housing 110 away from the outer housing 120 defines a first heat dissipation channel A1, and the inner housing 110 and the outer housing 120 define a second heat dissipation channel A2. A first fixed grille 112 is provided in the first heat dissipation channel A1, and a fan 200 is provided on the first fixed grille 112.

[0029] In this embodiment, the working state of the fan 200 is configured such that when the fan 200 is in working state, the fan 200 can drive the heat inside the box-type substation to pass through the first heat dissipation channel A1 and the second heat dissipation channel A2 in sequence and finally dissipate the heat to the external environment.

[0030] In some embodiments, the operating state of the fan 200 can also be configured such that when the fan 200 is in the operating state, the fan 200 can drive the airflow outside the box-type substation to pass through the second heat dissipation channel A2 and the first heat dissipation channel A1 in sequence and finally enter the interior of the box-type substation to achieve cooling of the interior of the substation.

[0031] Please see Figure 2A second fixed grille 122 is provided in the second heat dissipation channel A2. The setting of the second fixed grille 122 makes the heat dissipation device present a semi-closed structure. In order to prevent impurities in the external environment from entering the heat dissipation device and the substation through the second fixed grille 122, in this embodiment, a filter assembly 300 is arranged on the second fixed grille 122. The filter assembly 300 includes a plurality of filter elements that are stacked along the second direction.

[0032] It should be noted that the first direction specifically refers to the radial direction along the shell 100, and the second direction specifically refers to the height direction along the shell 100.

[0033] It is understandable that the filter can remove impurities in the passing airflow to isolate the substation from the external environment and prevent impurities from the external environment from entering the heat dissipation device and the substation through the second fixed grille 122.

[0034] The heat dissipation device provided in this embodiment is connected to the external environment through the second fixed grille 122 and is in a semi-enclosed form. By setting the filter component 300 on the second fixed grille 122, external impurities are prevented from entering the heat dissipation device and the substation through the semi-enclosed area of ​​the second fixed grille 122, thereby preventing external impurities from accumulating on the lines and equipment and affecting the heat dissipation effect of the lines and equipment.

[0035] Please continue reading. Figure 1 In this embodiment, both the inner shell 110 and the outer shell 120 are cylindrical structures. Compared with other structures (such as square ventilation structures), the cylindrical structure has higher ventilation efficiency. In addition, in terms of manufacturing process, the cylindrical structure can be produced by rolling, which is convenient for processing and has better airtightness, i.e., a higher dustproof and waterproof rating.

[0036] In this embodiment, a top cover 121 is provided at one end of the outer shell 120, and a connecting plate 111 is provided at the end of the inner shell 110 away from the top cover 121.

[0037] The top cover 121 is used to seal the top of the heat dissipation device. On the one hand, the top cover 121 can prevent external impurities (such as rainwater and dust) from falling directly into the heat dissipation device. On the other hand, the top cover 121 plays a deflection role, so that the airflow can be deflected from the first heat dissipation channel A1 to the second heat dissipation channel A2 / from the second heat dissipation channel A2 to the first heat dissipation channel A1 under the action of the fan 200.

[0038] Furthermore, since the top cover 121 is in direct contact with the external environment, in order to avoid the accumulation of external impurities (such as rainwater / dust) on the top cover 121, in this embodiment, the top cover 121 has a conical structure, specifically a conical top cover.

[0039] Understandably, when external impurities come into contact with the conical top cover 121, they can naturally slide off the conical surface of the top cover 121 under the action of gravity, thereby preventing external impurities from accumulating on the top cover 121 and affecting the heat dissipation effect.

[0040] In actual operation, the temperature on the outside of the top cover 121 is usually higher than that on the inside when exposed to the external environment. When the box-type substation is unloaded, condensation will occur on the inside of the top cover 121 due to the temperature difference between the inside and outside of the top cover 121.

[0041] Please see Figure 3 and Figure 5 In order to avoid condensation on the inside of the top cover 121, in this embodiment, an inner top cover 124 is provided on the side of the top cover 121 near the inner shell 110. The inner top cover 124 has a conical structure similar to the top cover 121. A heat insulation chamber 125 is formed between the inner top cover 124 and the top cover 121. The heat insulation chamber 125 is filled with heat insulation material.

[0042] In some embodiments, the insulation material can be glass wool. By providing an insulation chamber 125, the insulation effect of the top cover 121 is increased, and the occurrence of condensation is reduced.

[0043] Furthermore, a solar film 1211 is attached to the surface of the top cover 121 away from the inner shell 110. At the same time, an additional heating plate 1241 is attached to the surface of the inner top cover 124 away from the top cover 121. The heating plate 1241 is electrically connected to the solar film 1211.

[0044] Understandably, the solar thin film 1211 can convert solar energy into electrical energy and drive the heating plate 1241. The solar thin film 1211 can provide electrical energy to the heating plate 1241, so that the heating plate 1241 can heat the inner top cover 124 and the top cover 121 when the box-type substation is in an unloaded state, thereby increasing the heat preservation effect of the top cover 121 and reducing the occurrence of condensation.

[0045] In this embodiment, the heat dissipation device can be connected to the prefabricated substation via the connecting plate 111; for example, the connecting plate 111 is connected to the prefabricated substation via an energy storage seeding process.

[0046] Please see Figure 3 and Figure 4 In this embodiment, the multiple filter elements that are stacked along the second direction include a first filter layer 310 and a second filter layer 320 stacked on the first filter layer 310; the first filter layer 310 and the second filter layer 320 are dustproof cotton with different filtration accuracies.

[0047] In one specific embodiment, the first filter layer 310 is coarse filter cotton, specifically H-grade G3 cotton; the second filter layer 320 is medium-efficiency / high-efficiency filter cotton, specifically F-grade dustproof filter cotton.

[0048] It should be noted that the arrangement of the first filter layer 310 and the second filter layer 320 in the second direction can be adjusted according to actual working needs; for example, in some cases, the second filter layer 320 overlaps and is arranged above the first filter layer 310; in other cases, the first filter layer 310 overlaps and is arranged above the second filter layer 320. Typically, the airflow is selected to preferentially pass through the coarse filter cotton, and then through the medium / high efficiency filter cotton.

[0049] Please see Figure 2 In this embodiment, a flow guide grille 123 is provided on the side of the second fixed grille 122 away from the filter assembly 300. The flow guide grille 123 can guide the airflow through the second heat dissipation channel A2, increase the airflow velocity, and thus improve the heat dissipation efficiency. On the other hand, it can also block some external impurities from entering the heat dissipation device through the second fixed grille 122.

[0050] Please see Figure 2 and Figure 3 In order to improve the heat dissipation effect of the heat dissipation device, in this embodiment, the fan 200 includes a fan hub 210 and multiple blades 220 connected to the fan hub 210; a guide tube 400 is provided between the multiple blades 220 and the inner wall of the inner shell 110.

[0051] Specifically, the airflow path is as follows: when passing through the first heat dissipation channel A1 to the second heat dissipation channel A2, the airflow is rectified by the guide tube 400. On the one hand, it can make the originally turbulent airflow driven by the fan 200 more uniform and orderly, reducing mutual interference and energy loss of the airflow. On the other hand, it can help the airflow to be discharged more smoothly, reduce resistance, thereby increasing the air volume to a certain extent and improving the airflow delivery efficiency.

[0052] Furthermore, the length of the blade 220 extending into the guide tube 400 is... The length of the guide tube 400 in the second direction is ,in, .

[0053] The heat dissipation device provided in this embodiment has at least the following technical effects: (1) By setting a filter assembly 300 on the second fixed grid 122, external impurities are prevented from entering the heat dissipation device and the substation through the semi-enclosed area of ​​the second fixed grid 122. (2) A guide tube 400 is provided to rectify the relatively turbulent airflow driven by the fan 200, thereby improving the heat dissipation effect of the heat dissipation device. (3) Both the inner shell 110 and the outer shell 120 are cylindrical structures, which are simple to process, have high ventilation efficiency and good sealing performance compared with other structures (such as square ventilation structures); (4) The top cover 121 has a conical structure. The conical structure can prevent external impurities (such as rainwater / dust) from accumulating on the top cover 121, thus avoiding the impact of heat dissipation due to the accumulation of external impurities on the top cover 121.

[0054] (5) An inner top cover 124 is provided inside the top cover 121. A heat insulation chamber 125 is formed between the inner top cover 124 and the top cover 121. The heat insulation chamber 125 can increase the heat preservation effect of the top cover 121 and reduce the occurrence of condensation. At the same time, a solar film 1211 is attached to the surface of the top cover 121 away from the inner shell 110, and a heating plate 1241 is attached to the surface of the inner top cover 124 away from the top cover 121. The solar film 1211 can provide electrical energy to the heating plate 1241, so that the heating plate 1241 can heat the inner top cover 124 and the top cover 121, thereby increasing the heat preservation effect of the top cover 121 and reducing the occurrence of condensation.

[0055] Example 2: Please see Figure 6 and Figure 7 This embodiment provides a prefabricated substation, which is equipped with multiple heat dissipation devices as described in Embodiment 1 for heat dissipation of the prefabricated substation.

[0056] In this embodiment, the prefabricated substation includes a housing 500 and a top surface 510 disposed on the housing 500. The housing 500 and the top surface 510 together define a substation chamber for mounting lines and equipment. A heat dissipation device is disposed on the top surface 510 of the housing via the connecting plate 111 and is connected to the substation chamber.

[0057] Please see Figure 7 To prevent external impurities from entering the substation chamber through the connection between the heat dissipation device and the top surface 510 of the enclosure, in this embodiment, a flange is provided on the top surface 510 of the enclosure, and an installation groove 511 is formed between the flange and the top surface 510 of the enclosure. The end of the inner shell 110 near the connecting plate 111 extends outward and is inserted into the installation groove 511; a sealing gasket 512 is provided between the connecting plate 111 and the top surface 510 of the enclosure.

[0058] In one specific embodiment, the flange height is 8mm, and the sealing gasket 512 is a nitrile gasket with a compression of 30%. By providing the flange and the sealing gasket 512, water stains or other impurities can be effectively reduced from entering the substation chamber through the connection between the heat dissipation device and the top surface 510 of the enclosure.

[0059] In some embodiments, the connection between the heat dissipation device and the top surface 510 of the housing is further filled with waterproof sealant, and the waterproof sealant is wrapped with butyl tape for edge sealing to further improve the waterproof effect.

[0060] Furthermore, the connecting plate 111 is connected to the box-type substation through an energy storage nailing process, which improves the structural strength and further enhances the waterproof effect at the connection between the heat dissipation device and the top surface 510 of the box.

[0061] This embodiment also provides a box-type energy storage unit, which includes the aforementioned box-type substation and / or the heat dissipation device provided in Embodiment 1.

[0062] The prefabricated substation and prefabricated energy storage unit provided in this embodiment have good heat dissipation capabilities and good sealing performance, thereby preventing external impurities from entering the substation chamber through the connection between the heat dissipation device and the top surface 510 of the enclosure.

[0063] Example 3: Please see Figure 8 This embodiment also provides a heat dissipation device, whose overall structure, working principle and technical effect are basically the same as those of Embodiment 1. The difference is that in this embodiment, a baffle plate 410 is provided between the outer side of the guide tube 400 and the inner side of the inner shell 110.

[0064] In one specific embodiment, the baffle plate 410 has a ring-shaped structure and is fixedly disposed between the outer side of the guide tube 400 and the inner side of the inner shell 110, and is flush with the upper end face of the guide tube 400 and the inner shell 110. It is used to block part of the airflow from entering between the outer side of the guide tube 400 and the inner side of the inner shell 110, so as to reduce airflow loss and further improve the heat dissipation effect of the heat dissipation device.

[0065] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
