Abstract
Description
Technical Field
[0001] This application relates to the field of protective structure technology, and in particular to a bottom shroud for a high-efficiency ventilation energy storage machine. Background Technology
[0002] When an energy storage unit is working, the internal components generate heat. If this heat is not dissipated in time, the motherboard temperature will become too high, forcing a reduction in working efficiency. Therefore, an air-cooling mechanism is usually configured for the energy storage unit. The fan used for air cooling is protected by a fan shroud structure. The existing fan shroud structure is connected to the energy storage unit cabinet by bolts. Since the cabinet will continuously vibrate when the energy storage unit is working, the connecting parts are prone to fatigue damage. Utility Model Content
[0003] The purpose of this application is to provide a high-efficiency ventilation energy storage machine bottom shroud that can extend the service life of the connectors.
[0004] To achieve the above objectives, this application provides a bottom hood for a high-efficiency ventilated energy storage unit: including a protective cover with an open upper end, the protective cover having several convection grooves penetrating the inner and outer walls, a bushing at the geometric center of the inner bottom of the protective cover, an inner ring at the upper end of the protective cover, a connecting plate between the inner ring and the protective cover, and at least three ear plates on the outer side of the connecting plate, each ear plate having a connecting hole penetrating the upper and lower surfaces for bolts and other connecting parts to pass through, thereby fixing the hood to the bottom of the energy storage unit cabinet.
[0005] As a preferred embodiment, the protective cover is a rotating body, and the axis of the bushing is collinear with the axis of the protective cover, which provides auxiliary constraint to the main shaft of the fan blades and further improves the stability of the fan during operation.
[0006] As a preferred embodiment, the convection channels are straight, and all the convection channels are equidistantly arranged along a radial line of the protective cover, which facilitates demolding of the entire bottom wind cover after casting.
[0007] As a preferred embodiment, the convection channel is disconnected at the bushing to ensure that the bottom of the bushing has sufficient material for support.
[0008] As a preferred embodiment, the connecting plate is coaxial with the protective cover, and all the ear plates are equidistantly arranged around the axis of the connecting plate, so that the connecting parts used to achieve constraint are evenly distributed when the bottom wind cover is installed.
[0009] As a preferred embodiment, the outer diameter of the connecting plate is larger than the outer diameter of the protective cover, and the outer side of the protective cover and the lower surface of the connecting plate have heat dissipation ribs, which can improve both heat dissipation efficiency and structural strength.
[0010] As a preferred embodiment, the inner ring is coaxial with the protective cover. The upper edge of the inner ring is provided with a positioning groove for engaging with the protrusion on the inner wall of the mounting groove at the bottom of the energy storage unit, thus accommodating the rotation of the bottom wind cover relative to the energy storage unit cabinet and allowing the inner ring to better share the shear stress on the connecting parts.
[0011] As a preferred embodiment, there are several positioning slots, which are arranged equidistantly around the axis of the inner ring to increase the uniformity of force on the inner ring.
[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) A protective cover with an open top, wherein the protective cover has several convection grooves that penetrate the inner and outer walls, a bushing is located at the geometric center of the inner bottom of the protective cover, an inner ring is located at the upper end of the protective cover, a connecting plate is located between the inner ring and the protective cover, and the outer side of the connecting plate has at least three ear plates, each of the ear plates having a connecting hole that penetrates the upper and lower surfaces. (2) By designing a bushing structure at the bottom of the shroud to cooperate with the main shaft of the fan blades, the operating stability of the fan can be further improved, thereby reducing the vibration of the energy storage cabinet and further reducing the fatigue damage of the connecting parts.

[0019] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0020] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0021] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0022] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0023] like Figure 1-5 The high-efficiency ventilation energy storage machine shown has a bottom shroud, including an open protective cover 1 at the top. The protective cover 1 is a rotating body, and is a flat cylindrical shape used to accommodate the fan blades. The protective cover 1 has several convection grooves 101 that penetrate the inner and outer walls. The convection grooves 101 penetrate not only the bottom of the protective cover 1, but also the side walls of the protective cover 1. The convection grooves 101 are straight and densely distributed, allowing airflow to pass through efficiently. All the convection grooves 101 are equidistantly arranged along a radial line of the protective cover 1 for easy demolding. There is a bushing 5 at the geometric center of the inner bottom of the protective cover 1, which is used to cooperate with the main shaft of the fan blades to form a rotating pair. The axis of the bushing 5 is collinear with the axis of the protective cover 1. The convection grooves 101 are interrupted at the bushing 5. The material of the protective cover 1 at the bottom of the bushing 5 is solid, which can well ensure the structural stability of the bushing 5.
[0024] The upper end of the protective cover 1 has an embedded ring 4 for embedding into the mounting groove at the bottom of the energy storage cabinet. The embedded ring 4 is coaxial with the protective cover 1. The upper edge of the embedded ring 4 has a positioning slot 401. In fact, there are several positioning slots 401. These positioning slots 401 are equidistantly arranged around the axis of the embedded ring 4 to fit with the protrusion structure on the inner wall of the mounting groove at the bottom of the energy storage cabinet, so as to achieve installation positioning and improve the structural stability after installation.
[0025] Between the inner ring 4 and the protective cover 1 is the largest connecting plate 2. The connecting plate 2 is coaxial with the protective cover 1. The outer side of the connecting plate 2 has at least three ear plates 201. All ear plates 201 are equidistantly arranged around the axis of the connecting plate 2, and each ear plate 201 has a connecting hole 202 that passes through the upper and lower surfaces, through which bolts and other connecting parts pass and are connected to the screw hole at the bottom of the energy storage unit.
[0026] The outer diameter of the connecting plate 2 is larger than the outer diameter of the protective cover 1. There is a heat dissipation rib 3 between the outer side of the protective cover 1 and the lower surface of the connecting plate 2. The heat dissipation rib 3 is located on the side of the protective cover 1 where the convection groove 101 is not opened. On the one hand, it can increase the outer surface area of the entire wind cover and improve the heat dissipation efficiency; on the other hand, it can improve the structural strength between the protective cover 1 and the connecting plate 2.
[0027] Working principle: When in use, first fix the fan in the mounting groove at the bottom of the energy storage unit, then put the fan cover under the fan, so that the main shaft of the fan blade is inserted into the bushing 5, and the inner ring 4 is embedded into the mounting groove at the bottom of the energy storage unit until the positioning slot 401 is fully engaged with the protrusion on the inner wall of the mounting groove. Finally, use bolts to pass through the connecting hole 202 of the ear plate 201 to fix the fan cover to the bottom of the energy storage unit.
[0028] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
