Description

Electrical device

Technical Field

Embodiments of the present disclosure relate to the field of electrical equipment, and more particularly, to electrical equipment that utilizes forced convection for cooling.

Background

Electrical equipment, such as frequency converters, servomotors, soft starters and the like, typically require cooling of the body of the electrical equipment by means of a forced air flow generated by a cooling assembly, such as a fan. The cooling module requires regular maintenance or replacement to ensure optimal cooling.

In current production of electrical equipment, the cooling assembly is typically integrated within the body of the electrical equipment, such as the upper or lower portion of the electrical equipment. The position becomes unchangeable after the cooling assembly is integrated. However, in an actual usage scenario, the electrical equipment needs to be installed in a different working location. For example, electrical equipment may be installed near a fixed bottom surface (such as the floor or the bottom of a cabinet), which may be detrimental to maintenance and replacement of cooling components if fans are integrated into the lower portion of the electrical equipment. Conversely, if the electrical equipment is installed at a location where there is an obstruction on the top (such as a wall top or a top surface of a cabinet), maintenance and replacement of the cooling module may also be affected if the fan is integrated on the top of the electrical equipment.

Furthermore, in industrial applications, electrical equipment sometimes needs to be moved to different environments of use, which may place a non-fixed demand on the location of the cooling assembly in order to facilitate installation and maintenance of the cooling assembly. That is, depending on the installation environment, it is sometimes desirable that the cooling module be installed on the upper portion of the electrical equipment, and sometimes it be on the lower portion of the electrical equipment.

Therefore, it is desirable to provide an electrical apparatus capable of solving the above-described problems.

SUMMERY OF THE UTILITY MODEL

In view of the above, embodiments of the present disclosure provide an electrical device to at least partially solve the above problems and other potential problems in the conventional art.

An electrical apparatus 100 according to an exemplary embodiment of the present disclosure will be described in detail below with reference to fig. 1 to 4. In the embodiment of the present disclosure, the electrical device 100 may be one or more of a servo motor, a soft starter, a high voltage inverter, a medium voltage inverter, and a low voltage inverter. It should be understood that electrical device 100 may also be any other type of device that requires forced convection cooling or semi-forced convection cooling with a fan, and the present disclosure is not limited thereto.

Reference is first made to fig. 1 and 2. Fig. 1 shows an exploded view of an electrical device 100 according to an embodiment of the present disclosure, wherein the cooling assembly 3 is to be coupled to the first coupling portion 13. Fig. 2 shows an exploded view of the electrical device 100 according to fig. 1, wherein the cooling assembly 3 is to be coupled to the second coupling portion 15. In the example of fig. 1 and 2, the electrical device 100 is shown in the form of a frequency converter, but it is to be understood that, as previously described, embodiments of the invention are not limited to the above-described forms.

In such an embodiment, the electrical apparatus 100 may comprise a body 1, a cooling assembly 3 and a grille 5. The body 1, the cooling assembly 3 and the grille 5 can be assembled in a suitable manner to form an integral structure of the electrical apparatus 100. For example, as shown in fig. 1, the cooling module 3 is coupled to a lower portion of the body 1, and the grill 5 is coupled to an upper portion of the body 1. Whereas in the example of fig. 2, the cooling assembly 3 is coupled at an upper portion of the body 1 and the grill 5 is coupled at a lower portion of the body 1.

In some embodiments, the body 1 may be used to house various functional units of the electrical apparatus 100, for example, may include one or more of a rectifying unit, a filtering unit, an inverting unit, a braking unit, a driving unit, a detecting unit, or a micro-processing unit. In one embodiment, as shown in fig. 1 and 2, the body 1 may be a substantially rectangular parallelepiped structure. It should be understood that the body 1 may also be other structures, such as cubic, polygonal, and other irregular structures, and the present disclosure is not limited thereto.

In such an embodiment, the body 1 may have a first coupling portion 13 and a second coupling portion 15, and the first coupling portion 13 and the second coupling portion 15 may be oppositely disposed. The first and second coupling portions 13, 15 may be, for example, open mating structures that mate with the cooling assembly 3 and the grille 5 to receive the cooling assembly 3 and the grille 5. In this embodiment, the electrical device 100 may be fixed in a substantially vertical orientation, for example. With this arrangement, as shown in fig. 1, the first coupling portion 13 may be located at a lower portion of the body 1 for coupling the cooling assembly 3. Accordingly, a second coupling part 15 may be located at an upper portion of the body 1 for coupling the grating 5. In fig. 2, the first coupling portion 13 may be used for coupling the grille 5, and the second coupling portion 15 is used for coupling the cooling member 3.

It should be understood that the above description is merely exemplary, and the present disclosure is not limited to the specific shapes and relative positions of the first coupling portion 13 and the second coupling portion 15. That is, the first coupling portion 13 and the second coupling portion 15 may be any suitable shape as long as they can be fitted with the cooling member 3 and the grill 5. It should be understood that, since both the first and second coupling portions 13 and 15 may couple any one of the cooling member 3 and the grill 5, the first and second coupling portions 13 and 15 may be arbitrarily disposed at an upper or lower portion of the body 1 according to a relative positional relationship.

In such an embodiment, as shown in fig. 1, the cooling module 3 may be detachably coupled to the first coupling portion 13 to blow air for cooling into the body 1. And, the optional grille 5 can be detachably coupled to the second coupling portion 15 to isolate the body 1, so as to prevent electric shock or scalding accidents caused by mistaken touch on the body. It should be noted that only an example of the lower intake air cooled electrical apparatus 100 is described herein. For some embodiments of the electrical apparatus 100 with the upper air intake, when the cooling module 3 is installed at the lower portion of the body 1, the cooling module 3 may draw air for cooling into the body 1 for cooling of the body 1.

As shown in fig. 2, the cooling assembly 3 may be detachably coupled to the second coupling portion 15 to suck air for cooling into the body 1. Moreover, the optional grille 5 can be detachably coupled to the first coupling portion 13 to isolate the body 1, so as to prevent electric shock or scalding accidents caused by mistaken touch on the body. It should be noted that only an example of the lower intake air cooled electrical apparatus 100 is described herein. For some embodiments of the electrical apparatus 100 with the upper intake air, when the cooling module 3 is installed at the upper portion of the body 1, the cooling module 3 may blow air for cooling into the body 1 for cooling of the body 1.

In one embodiment, as shown in fig. 1 and 2, the cooling module 3 includes a joint 33 and a fan 31, the joint 33 may be coupled to one of the first coupling portion 13 and the second coupling portion 15, and the fan 31 may be detachably mounted on the joint 33. With this arrangement, the fan 31 and the joint 33 can be coupled to either end of the body 1 to meet the requirements in different installation scenarios. Meanwhile, the replacement and maintenance of the components at the later stage are facilitated.

Specifically, in fig. 1, the joint 33 is coupled to the first coupling portion 13. In fig. 2, the joint 33 is coupled to the second coupling portion 15. It should be noted that the above-mentioned coupling manner is only illustrative, and any other manner without departing from the inventive concept is also conceivable, for example, in case no grille 5 is provided, in order to better achieve cooling, two cooling assemblies 3 including a fan 31 and a joint 33 may be installed in the first joint portion 13 and the second joint portion 15, respectively, to achieve stronger air convection and improve cooling effect.

In some embodiments, the pitch of the grille 5 may be no greater than 12.5mm, such as 10mm, 8mm, 5mm or any other suitable pitch to prevent foreign objects of a corresponding diameter from entering the electrical equipment and to ensure that air can pass smoothly through the grille. It should be understood that the grid pitch can be set by one skilled in the art according to actual needs, for example, it is set to be larger than 12.5mm, as long as the specific use requirements can be met, and the disclosure does not limit the grid pitch. In addition, it should be noted that the grille 5 is an optional component, and a person skilled in the art can select whether to arrange the grille 5 according to actual needs.

In one embodiment, as shown in fig. 1 and 2, the joint 33 may include a base plate 331 and a sidewall 333, the sidewall 333 may be disposed at an edge of the base plate 331, and the fan 31 may be mounted on the base plate 331. With this arrangement, the joint is simple in construction and easy to install and manufacture. In one embodiment, as shown in fig. 2, the engagement member 33 may be coupled to the body 1 via a snap-in member 337 provided on the side wall 333. The snap-in piece 337 may be realized as a snap-in structure which may be snap-fitted with a snap-fit mechanism provided on the first engagement portion 13 or the second engagement portion 15 to snap-in to the body 1 to effect engagement of the cooling assembly 3 with the body 1, as will be more clearly shown in fig. 4. It should be noted that the above examples are only exemplary, and any way of coupling the engaging member 33 to the body 1 is feasible, such as joggling, riveting, bolting, plugging, sleeving, pressing, bonding, welding, nesting, etc., and the disclosure is not limited thereto.

In such embodiments, as shown in fig. 1 and 2, the fan 31 may have a housing, and the blades of the fan 31 may be disposed within the housing of the fan 31. For example, the housing may be generally square, but it will be appreciated that any other suitable shape is possible. Generally, the area of the housing that receives the blades has a circular cross-section, but other suitable cross-sections may be used in embodiments of the present disclosure, such as square or rectangular cross-sections, and the like.

In one embodiment, a through opening 335 may be provided on the base 331, and the shape of the opening 335 may be adapted to the shape of the fan 31. In the example shown in fig. 1, the opening 335 is circular in shape to fit the cross-section of the area of the blades of the fan 31. With this arrangement, the opening 335 is provided in cooperation with the fan 31 to provide a motive force and passage for air into the body 1. It should be appreciated that the circular opening 335 described above is merely exemplary, and that the opening 335 may be any other suitable shape, as the present disclosure is not limited thereto.

In such embodiments, as shown in fig. 1 and 2, the fan 31 may include first and second opposing surfaces 313 and 315, wherein one of the first and second surfaces 313 and 315 may face the joint 33 in a case where the fan 31 is coupled to the first coupling portion 13, and the other of the first and second surfaces 313 and 315 may face the joint 33 in a case where the fan 31 is coupled to the second coupling portion 15.

Specifically, in one embodiment, as shown in fig. 1 and 2, when the fan 31 is coupled to the first coupling portion 13, the first surface 313 of the fan 31 may face the body 1, and at this time, the second surface 315 opposite thereto faces the joint 33. The second surface 315 of the fan 31 may face the body 1 when the fan 31 is coupled to the second coupling portion 15. At this time, the first surface 313 opposite thereto faces the engaging member 33. This is done, for example, when the cooling module 3 is moved from the first coupling portion 13 to the second coupling portion 15, because the direction of the flow of the blades of the fan 31 is fixed, the fan 31 needs to be installed in a reversed manner to ensure the uniform direction of the air flow (for example, when all the air-intake electrical devices are down). The manner of detachable engagement of the fan 31 and the engagement member 33 will be described in detail below in fig. 3.

Through such an arrangement, the flow direction of the air flow can be selected as required, and the cooling effect on the electrical equipment is ensured. Of course, it should be understood that a reverse motor may be provided for the fan 31 so that the uniformity of the direction of the air flow can be ensured by the reverse operation of the motor without adjusting the installation orientation of the fan 31, which is not limited by the present disclosure.

Fig. 3 shows an assembly schematic of the cooling assembly 3 of the electrical device 100 according to an embodiment of the present disclosure.

In one embodiment, as shown in fig. 3, at least one fixing leg 339 may be disposed on the base plate 331 of the cooling module 3. For example, the securing feet 339 may be 2, 4, 6, or more. The securing feet 339 may include, for example, one or more snap feet that are secured to a surface of the base 331 and may pivot at an angle. The housing of the fan 31 may be provided with a slot. One or more clips snap into slots cut in the housing of the fan 31 to secure the fan 31 to the base 331. The fixing legs 339 may be provided with elastic members, and when the fan 31 is fixed, the elastic members tightly attach the fan 31 to the substrate 331 by using the elastic force of the elastic members. When the fan 31 needs to be disassembled, the fan 31 can be easily disassembled by rotating the fixing legs 339 outward by an external force. With this arrangement, the fan 31 is fixed to the joint 33 in a simple manner, facilitating the mounting and dismounting of the fan 31.

In addition, when the fan 31 is detached, it can be turned 180 degrees upside down, and then the fan 31 is fixed to the substrate 331 by the same fixing leg 339 structure. With this arrangement, when the cooling module 3 is installed at different positions, the flow guiding direction of the blades of the fan 31 can be adjusted by detaching the fan 31, thereby satisfying a predetermined requirement.

It should be noted that the above-mentioned fixing manner is only an example, and any manner capable of fixing the fan 31 and the base plate 331 is feasible, such as clamping, joggling, riveting, bolting, plugging, sleeving, pressing, bonding, welding, nesting, and the like, and the disclosure is not limited thereto. As mentioned above, the control of the air flow direction can also be achieved by providing a reversing motor, which is not limited by the present disclosure.

Fig. 4 shows a schematic view of the electrical device 100 in an assembled state according to an embodiment of the present disclosure.

As shown in fig. 4, the cooling assembly 3 is coupled to the body 1, such as a first joint 13 (not shown). Specifically, in this embodiment, the engagement piece 33 is engaged to the body 1 by at least one snap piece 337. The clamping member 337 can be a press-type clamping structure, for example. In this structure, when installing, an installer can press the clamping piece 337 with an external force to install the cooling module 3 to the first joint 13, and then release the external force, the clamping piece of the clamping piece 337 extends outward, so as to clamp the cooling module 3 in the corresponding fitting groove of the first joint 13 to fix the cooling module 3. Accordingly, when disassembling, the operator only needs to press the clip piece 337 again so that the clip piece is disengaged from the mating groove, and the disassembly of the cooling assembly 3 can be achieved. It should be understood that the coupling of the cooling assembly 3 to the second joint 15 may also be realized with the same structure.

It should be noted that the above structure is only exemplary, and any way of enabling the cooling module 3 to be engaged with the body 1 is feasible, and the present disclosure is not limited thereto.

The electrical equipment 100 based on the scheme of the disclosure can optionally install the cooling assembly 3 at different positions of the body so as to meet the installation requirements under different use scenes. Furthermore, such an arrangement also facilitates maintenance and replacement of the cooling assembly.

Having described embodiments of the present disclosure, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
