When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 and fig. 2, an electrical apparatus according to an embodiment of the present invention includes a housing (not shown), an electronic component (not shown) mounted in the housing, and a heat dissipation device 100 for assisting the electronic component in dissipating heat. The electrical device may be a heat exchange device, such as an air conditioner outdoor unit, or other devices to which the heat dissipation apparatus 100 may be mounted, and is not limited herein.
As shown in fig. 1 and 3, the heat dissipation apparatus 100 includes a heat dissipation base 20 and a plurality of heat dissipation fins 40 detachably mounted on the heat dissipation base 20, wherein heat generated by electronic components in the electrical equipment can be transferred to the heat dissipation base 20 and then dissipated through the heat dissipation fins 40.
The heat sink 20 includes a base plate 21 and mounting fins 23 which are integrally formed. The substrate 21 has a substantially rectangular plate-like structure in cross section, the longitudinal direction of the substrate 21 is a first direction, the width direction is a second direction, the thickness direction of the substrate 21 is a third direction, and the first direction, the second direction, and the third direction intersect with each other. Preferably, the first direction, the second direction and the third direction are perpendicular to each other. The plurality of mounting fins 23 are arranged on one side surface of the base plate 21 at intervals along the first direction, and a mounting groove 25 is formed between every two adjacent mounting fins 23. In this way, a plurality of mounting grooves 25 arranged at intervals in the first direction are formed on the heat dissipation base 20 to mount the heat dissipation fins 40.
In some embodiments, the mounting fins 23 are in an elongated structure, the length direction of the mounting fins 23 extends along the second direction, and the length of the mounting fins 23 is slightly shorter than the width of the base plate 21, the width direction of the mounting fins 23 extends along the first direction, and a mounting groove 25 extending along the second direction and having a length slightly shorter than the length of the base plate 21 is formed between every two adjacent mounting fins 23. It will be appreciated that the specific configuration of the mounting fin 23 is not limited, and in some embodiments, the mounting fin 23 is a solid structure, thereby providing greater strength while being less difficult to form. In other embodiments, the mounting fins 23 are non-solid structures, and the mounting fins 23 are provided with heat dissipation grooves communicating with the external environment to form airflow channels, so as to reduce the weight of the heat dissipation base 20 and improve the heat dissipation efficiency of the heat dissipation device 100. Specifically, in one embodiment, the heat dissipation groove of the mounting fin 23 extends in the second direction and communicates with both ends of the mounting fin 23 in the second direction, so that the air flow can pass through the heat dissipation groove in the second direction to take off part of the heat in the mounting fin 23.
Specifically, in some embodiments, the thickness of the base plate 21 is less than 10mm, and the dimension of the mounting fins 23 in the third direction (i.e., the height of the mounting fins 23) is preferably 3mm, so that the heat dissipation fins 40 can be firmly fixed, and the weight of the heat dissipation base 20 can be reduced.
The heat dissipation fins 40 are made of rigid elastic materials (such as stainless steel) and can be restored to deform in the first direction, and the size of the heat dissipation fins 40 in the first direction can be reduced under the action of external force until the heat dissipation fins are clamped in the mounting grooves 25. In this way, one end of one heat dissipation fin 40 is detachably inserted into one mounting groove 25 of the heat dissipation base 20, and then a plurality of heat dissipation fins 40 are arranged at intervals along the first direction on one side of the heat dissipation base 20. It can be understood that different types of mounting seats and different types and numbers of heat dissipation fins 40 can be selected to be matched with each other to form different heat dissipation devices 100 according to requirements, so that requirements of different electrical equipment are met, the generalization rate of the heat dissipation devices 100 is effectively improved, and the production cost and the storage cost are reduced.
Referring to fig. 1, 3 and 4, each of the heat dissipating fins 40 includes a first heat dissipating side wall 41, a second heat dissipating side wall 43 and a connecting top wall 45, and the first heat dissipating side plate 41, the second heat dissipating side wall 43 and the connecting top wall 45 are all rectangular plate-shaped structures. The first heat dissipation sidewall 41 and the second heat dissipation sidewall 43 are spaced and parallel to each other in the first direction, and an orthographic projection of the first heat dissipation sidewall 41 on the second heat dissipation sidewall 43 coincides with an edge of the second heat dissipation sidewall 43. Two sides of the connecting top wall 45 in the first direction are respectively connected to the ends of the first heat dissipating sidewall 41 and the second heat dissipating sidewall 43 away from the heat dissipating base 20. Therefore, the heat dissipation fins 40 form a structure independent from the heat dissipation base 20, the heat dissipation air channels 47 are formed between the first heat dissipation side wall 41 and the second heat dissipation side wall 43, and each heat dissipation air channel 47 extends from the heat dissipation base 20 to one end of the heat dissipation fins 40 away from the heat dissipation base 20 along the third direction and is communicated with two ends of the heat dissipation fins 40 in the second direction.
Thus, each fin 40 is provided with a heat dissipation air duct 47 communicating the heat dissipation base 20 with the external environment, and the air flow can pass through the heat dissipation air duct 47 to take away the heat on the heat dissipation base 20. Compared with the solid or other heat dissipation fins 40, the heat dissipation fins 40 with the heat dissipation air ducts 47 communicated with the heat dissipation base 20 have higher heat dissipation efficiency, and the weight of the heat dissipation device 100 is greatly reduced, which is beneficial to the light weight of the electrical equipment.
Further, in an embodiment, the heat dissipating fin 40 further includes a plurality of air guiding sheets 49, the air guiding sheets 49 are disposed on the first heat dissipating side wall 41 and the second heat dissipating side wall 43 facing the heat dissipating air duct 47, and the plurality of air guiding sheets 49 are arranged at intervals from one end of the heat dissipating fin 40 close to the heat dissipating base 20 to one end of the heat dissipating fin 40 away from the heat dissipating base 20 along the third direction, so as to perform a flow guiding function, so that the air flow flows from one end of the heat dissipating fin 40 in the second direction to the other end of the heat dissipating fin 40 in the second direction to take away the heat on the heat dissipating.
Specifically, each of the air guiding plates 49 is a plate-shaped structure extending along the second direction, and the air guiding plate 49 extends obliquely from one of the first heat dissipating sidewall 41 and the second heat dissipating sidewall 43 to the other of the first heat dissipating sidewall 41 and the second heat dissipating sidewall 43. Preferably, the air guiding sheet 49 extends upwards from the first heat dissipating sidewall 41 or the second heat dissipating sidewall 43 in a direction away from the heat dissipating base 20, and an included angle between the air guiding sheet 49 and the first heat dissipating sidewall 41 is 45 °, so as to have a better air guiding effect. It is understood that, in some other embodiments, the air guiding plate 49 may be disposed on only one of the first heat dissipating sidewall 41 or the second heat dissipating sidewall 43, the air guiding plate 49 may extend obliquely toward the heat dissipating base 20, the angle of inclination of the air guiding plate 49 is not limited to 45 °, and the air guiding plate 49 may be disposed according to actual requirements.
In the heat dissipation device 100 and the electrical equipment provided with the same, because the heat dissipation fins 40 of the heat dissipation device 100 are detachably mounted on the heat dissipation base 20, different types of heat dissipation bases 20 and different types and numbers of heat dissipation fins 40 can be selected to be mutually combined to form heat dissipation devices 100 with different structures according to needs, so as to meet different needs, thereby having higher universality. Moreover, the heat dissipation air duct 47 formed on the heat dissipation fin 40 effectively improves the heat dissipation efficiency and reduces the weight of the heat dissipation device 100, thereby improving the working stability of the electrical equipment, prolonging the service life of the electrical equipment and contributing to the lightweight development of the electrical equipment.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
