Abstract
Description
Technical Field
[0001] This utility model relates to the field of enclosure ventilation and heat dissipation structure technology, and in particular to a top cover, enclosure, box-type power station and box-type house. Background Technology
[0002] The prefabricated power station of this application consists of a prefabricated enclosure and electrical or electronic equipment placed therein to achieve the set functions, including prefabricated substations, prefabricated charging stations, prefabricated energy storage stations, prefabricated ring main units, communication base stations, computer stations, etc.
[0003] The aforementioned prefabricated substations generate a significant amount of heat during operation, which needs to be dissipated from the enclosure. Achieving fast and convenient charging for new energy vehicles places higher demands on the power output of these prefabricated substations, making heat dissipation a critical issue. Simultaneously, to ensure the safe operation of components inside the enclosure, higher protection levels are required, such as IP44 or higher. However, increasing the protection level, especially IP4X which requires the perforated plate aperture to be no larger than 1 mm, presents challenges. Current technology has poor natural heat dissipation capabilities, heavily relying on forced cooling fans. This results in high energy consumption, and the fans are vulnerable components, meaning that fan failures may go undetected, posing a threat to the safe operation of the equipment. Insufficient or reduced heat dissipation leads to increased internal temperature, reducing the equipment's lifespan. To control the operating temperature, the output capacity of the equipment is often forced to be reduced, resulting in decreased functionality and essentially a loss of investment.
[0004] The container house described in this application is an integrated unit consisting of a container and electrical equipment or furniture placed inside to achieve a set function, including RVs, yachts, container houses, gazebos, etc. Existing container houses typically have screens installed on the windows to keep out mosquitoes, but these screens obstruct the view. Utility Model Content
[0005] The purpose of this utility model is to provide a top cover, a box body, a box-type power station, and a box-type house to solve the shortcomings of the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model discloses a top cover, including a cover plate, an upper baffle, a lower baffle, and a mesh plate. The cover plate includes a downwardly curved eaves. The upper baffle abuts against the cover plate. The lower baffle includes a bottom and at least one side. The mesh plate is located inside and below the cover plate, and its four sides abut against the lower baffle. The mesh plate and the cover plate are joined together to form a first air duct. The eaves, the upper baffle, and the lower baffle are staggered and joined together to form a curved second air duct.
[0007] Compared with the prior art, the beneficial effects of the top cover of this utility model are as follows: 1. The perforated plate is located inside the lower part of the cover plate, and its edges abut against the lower baffle. The area of the perforated plate is approximately four times the area of the eaves vent. For IP4X protection, the effective ventilation area of a single layer of 1 mm perforated plate accounts for approximately 25%, and the effective cross-section of the first air duct is equivalent to the 100% utilization rate of the eaves vent area. Compared with the prior art where the perforated plate is located below the eaves, the effective cross-section of the eaves vent is approximately 25% of the effective ventilation area of a single layer of 1 mm perforated plate plus approximately 60% of the effective ventilation area of a single layer of 12 mm perforated plate. The effective ventilation area of the two-layer perforated plate stacking scheme is only about 15%. The ventilation efficiency of this utility model can reach 6.7 times that of the prior art, significantly improving the ventilation and heat dissipation effect, reducing or even avoiding the use of forced cooling by fans, reducing energy consumption and failure rate, increasing equipment output capacity, and resulting in significant economic benefits. 2. The eaves, upper baffle and lower baffle are staggered to form a curved second air duct, which can achieve protection of IPX4 or above, protecting electrical and electronic equipment from failure or even damage due to water ingress in harsh environments.

[0020] Figure 4 This is a partial structural schematic diagram of the third embodiment of the present utility model. Detailed Implementation
[0021] To explain in detail the technical content, structural features, implementation principle, and achieved purpose and effect of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a top cover, including a cover plate 1, an upper baffle 2, a lower baffle 5, and a mesh plate 3. The cover plate 1 includes a downwardly curved eaves 9. The upper baffle 2 abuts against the cover plate 1. The lower baffle 5 includes a bottom and an inner side 4. The mesh plate 3 is located inside the lower part of the cover plate 1, and its edges abut against the lower baffle 5. The mesh plate 3 and the cover plate are combined to form a first air duct 11. The eaves 9, the upper baffle 2, and the lower baffle 5 are staggered and combined to form a curved second air duct 12.
[0023] like Figure 1 The schematic diagram of the first embodiment of this utility model shows that the cover plate 1 is provided with several ribs 13, and the mesh plate 3 is divided into several pieces by the ribs 13. The edge of the mesh plate 3 abuts against the lower baffle 5 and the ribs 13. This utility model provides a box body, including a box body 7 and a top cover, the top cover being connected and fixed to the box body 7. This utility model provides a box-type power station, including a box body and equipment 14 installed inside it. This utility model provides a box-type house, including a box body and equipment 14 installed inside it. The equipment 14, depending on the needs of use, can be electrical or electronic equipment, or electrical equipment or furniture, forming a whole to achieve the set functions, including box-type substations, box-type charging stations, box-type energy storage stations, box-type ring main units, communication base stations, computer stations, etc., as well as RVs, yachts, container houses, pavilions, etc.
[0024] like Figure 2 As shown Figure 1The schematic diagram of part 10, as a first embodiment of this utility model, shows that the lower baffle 5 also includes an outer side portion 8. The outer side portion 8 has several drainage holes (not shown) and several drainage tunnels 6 at its bottom, which communicate with the drainage holes. The outer side portion 8 also has several ventilation holes (not shown), the diameter of which is larger than the diameter of the mesh plate 3. The outer side portion 8 abuts against the cover plate 1. The outer side portion 8 can prevent small animals such as birds and mice from entering the interior of the box.
[0025] like Figure 1 and Figure 2 As shown, the perforated plate 3 is located inside and below the cover plate 1, and its edges abut against the lower baffle 5. The projected area of the cover plate 1 is 5 square meters, the eaves 9 extend out of the box body 7 by about 0.1 meters, the air vent area around the eaves 9 is 0.86 square meters, and the area of the perforated plate 3 is 3.5 square meters, which is about four times the air vent area of the eaves 9. Taking the top cover to achieve IP4X protection as an example, using a perforated plate with a 1 mm aperture, the effective ventilation area accounts for about 25%, the effective ventilation area of the perforated plate 3 is 0.88 square meters, and the effective cross-section of the first air duct 11 is equivalent to the 100% utilization rate of the air inlet area of the eaves 9. The lower baffle 5 can be formed by sheet metal bending to create the outer side 8, or by welding or bolting. The outer side 8 has an area of 1.43 square meters and several ventilation holes with a diameter of 12 mm. The effective ventilation area accounts for approximately 60%, and the effective ventilation area of the outer side 8 is 0.86 square meters. The effective cross-section of the second air duct 12 is comparable to the 100% utilization rate of the air inlet area of the eaves 9. This example illustrates that this invention does not reduce the effective ventilation area while meeting IP4X protection requirements.
[0026] Compared to existing technologies where perforated plates are placed under eaves, the effective ventilation area of the eaves duct is approximately 25% for a single layer of 1mm perforated plate and approximately 60% for a layer of 12mm perforated plate. In contrast, the effective ventilation area of the two-layer perforated plate stacking scheme is only about 15%. The ventilation efficiency of this invention is 6.7 times that of existing technologies, significantly improving ventilation and heat dissipation. It reduces or even eliminates the need for forced cooling with fans, lowers energy consumption and failure rate, increases equipment output capacity, and yields significant economic benefits.
[0027] The eaves 9, upper baffle 2, and lower baffle 5 are staggered to form a curved second air duct 12. The eaves 9 can block water spray. After water splashes from all directions enter the second air duct 12, they will be blocked by the outer side 8 of the lower baffle 5 and the upper baffle 2 in sequence. The splashes are further received by the lower baffle 5. The splashes are discharged from the top cover through the drainage tunnel 6 and the drainage hole. The drainage tunnel 6 can also prevent splashes from shooting into the upper baffle 2 from the drainage hole. The inner side 4 can further block splashes from overflowing into the box, thus achieving protection of IPX4 or higher, protecting electrical and electronic equipment from malfunction or even damage due to water ingress in harsh environments.
[0028] like Figure 3 The diagram shown is a structural schematic of the second embodiment of this utility model, including a cover plate 1, an upper baffle 2, a lower baffle 5, and a perforated plate 3. The cover plate 1 includes a downwardly curved eave 9. The upper baffle 2 abuts against the cover plate 1. The lower baffle 5 includes a bottom and an inner side 4. The perforated plate 3 is located inside and below the cover plate 1, and its edges abut against the lower baffle 5. The perforated plate 3 and the cover plate are combined to form a first air duct 11. The eave 9, the upper baffle 2, and the lower baffle 5 are staggered and combined to form a curved second air duct 12. The cover plate 1 has several ribs 13, and the perforated plate 3 is divided into several pieces by the ribs 13. The edges of the perforated plate 3 abut against the lower baffle 5 and the ribs 13. The perforated plate 3 has a slotted frame 15, which abuts against the lower baffle 5 and the ribs 13. The perforated plate 3 can be removed for cleaning or replacement.
[0029] like Figure 4 The diagram shown is a structural schematic of the third embodiment of this utility model, including a cover plate 1, an upper baffle 2, a lower baffle 5, and a perforated plate 3. The cover plate 1 includes a downwardly curved eave 9. The upper baffle 2 abuts against the cover plate 1. The lower baffle 5 includes a bottom and an inner side 4. The perforated plate 3 is located inside the lower part of the cover plate 1, and its edges abut against the lower baffle 5. The perforated plate 3 and the cover plate are joined together to form a first air duct 11. The eave 9, the upper baffle 2, and the lower baffle 5 are staggered and joined together to form a curved second air duct 12. The connection between the upper baffle 2 and the cover plate 1 includes an electric control device (not shown). The electric control device adjusts the position of the upper baffle 2, thereby changing the distance between the inner side 4 of the upper baffle 2 and the lower baffle 5, and adjusting the ventilation volume of the second air duct 12. The electric control device is a mature and conventional device, including a sensor, a control circuit, and an actuator (not shown). The third embodiment of this utility model can be applied to condensation and cold environments. When the sensor detects condensation or reaches the preset low temperature, the control circuit outputs a signal to instruct the actuator to adjust the position of the upper baffle 2, reduce the distance between the inner side 4 of the upper baffle 2 and the lower baffle 5, reduce the ventilation volume of the second air duct 12, or even close the second air duct 12, thereby reducing the heat loss inside the box, maintaining the normal operating temperature of the equipment 14, reducing the entry of external humid air, inhibiting condensation formation, and avoiding equipment failure due to electrical insulation failure.
[0030] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
