Fig. 3 is a schematic structural diagram of a frequency converter motor integrated machine according to an embodiment of the present disclosure.

Referring to fig. 3, in some embodiments, the connection between the first housing 201 and the second housing 202 has an external heat dissipation port 232, and the external heat dissipation port 232 communicates with the second accommodating chamber 212 and the external environment. The outer heat dissipation port 232 may provide a passage for air to flow out of the second receiving chamber 212 so that air carrying heat emitted by the frequency converter 204 may exit the second receiving chamber 212 for purposes of dissipating heat from the frequency converter 204.

In some embodiments, the outer heat dissipation port 232 may be a gap formed by the connection between the second housing 202 and the first housing 201. For example, the horizontal cross section of the second housing 202 may be a regular hexagon with an enlarged horizontal cross section of the first housing 201, and the second housing 202 is disposed directly above the first housing 201, so that a joint between the second housing 202 and the first housing 201 has a gap generated by a mismatch of shapes, and the outer heat dissipation port 232 faces to the lower side of the second housing 202, so that part of air can escape into the external environment along the outer heat dissipation port 232 after entering the second accommodating cavity 212 through the heat dissipation window 222, and heat in the second accommodating cavity 212 is taken away.

In some embodiments, one end of the outer wall heat dissipating rib 231 may be connected to the outer heat dissipating opening 232, such that a heat dissipating outer air channel 241 is formed between the outer wall heat dissipating ribs 231. When the air in the second accommodating cavity 212 flows out of the external environment through the external heat dissipation port 232, the air flows in the heat dissipation external air channel 241 under the guiding action of the external heat dissipation ribs 231, and meanwhile, the heat emitted by the first housing 201 is taken away, so that the heat dissipation effect of the first housing 201 is improved.

The second shell 102 is communicated with the first shell 101, the heat dissipation inner air duct 121 in the first shell 101 is communicated with the first accommodating cavity 111, the second accommodating cavity 112 and the first accommodating cavity 111 and the external environment, so that the air flow entering the second accommodating cavity 112 from the heat dissipation window 122 can sequentially flow through the second accommodating cavity 112 and the heat dissipation inner air duct 121, heat generated by the frequency converter and the motor is taken away, and finally the heat flows back to the external environment from the lower part of the first accommodating cavity 111, so that the heat is taken away from the frequency converter motor integrated machine 100, and the purpose of heat dissipation of the frequency converter motor integrated machine 100 is achieved.

In some embodiments, the number of cooling windows 122 may be one and more than one, such as one, two, three, or four, etc. The number of the heat dissipating windows 122 may vary according to design requirements.

In this way, the fluidity of the air is advantageously improved, and the ventilation of the second housing 102 is improved, thereby improving the heat dissipation effect of the second housing 102.

The power module 114 is a heat generating structure in the frequency converter, and since the frequency converter cannot normally operate at high temperature for a long time, heat dissipation for the power module 114 is required in time. A heat dissipating structure 105 is disposed below the power module 114 to facilitate dissipating heat from the power module 114.

In some embodiments, the heat dissipation structure 105 may be disposed opposite to the heat dissipation window 122, so that the cooling air flowing into the heat dissipation window 122 timely takes away the heat conducted to the heat dissipation structure 105 by the power module 114 to dissipate the heat of the power module 114. For example, the heat dissipation structure 105 may include a heat dissipation fin 115, where the heat dissipation fin 115 includes a heat dissipation fin 115 mounting plate and heat dissipation fins, the heat dissipation fins are located on one surface of the heat dissipation surface mounting plate, and the other surface of the heat dissipation fin 115 mounting plate contacts the power module 114 to conduct heat of the power module 114 to the heat dissipation fins, the heat dissipation fins face to be consistent with the mutual faces of the pair of heat dissipation windows 122, and the heat dissipation fins may be fully contacted with cooling air flowing into the heat dissipation windows 122 to conduct heat into the cooling air flow, so as to achieve the purpose of dissipating heat of the power module 114.

In some embodiments, the heat sink 115 may be an aluminum alloy heat sink, a pure copper heat sink, or a copper aluminum composite heat sink.

Fig. 4 is a schematic structural diagram of a cooling fan according to an embodiment of the disclosure.

The cooling fan 125 may be an axial flow fan that is horizontally disposed, that is, an air inlet of the cooling fan 125 faces the top of the second housing 102, and an air outlet faces the bottom of the second housing 102, so that an air flow is formed in the integrated motor and inverter machine 100, and heat dissipation of the integrated motor and inverter machine 100 is promoted. It is understood that the type, number, arrangement, etc. of the cooling fans 125 may vary according to design requirements.

In some embodiments, the cooling fan 125 may also include a control device. The control device is electrically connected with the driving motor of the cooling fan 125, and the control device can control the power of the cooling fan 125 by controlling the rotation speed of the driving motor so as to control the rotation speed of the cooling fan 125.

The fan mounting bracket 135 may have a plurality of hollow areas to facilitate the passage of air flow from the second accommodating chamber 112 into the heat dissipation inner air duct 121.

The heat dissipation inner air duct 121 is located between the motor and the first housing 101, and the heat dissipation inner air duct 121 penetrates through the first accommodating cavity 111, communicates the second accommodating cavity 112 with the first accommodating cavity 111, and also communicates the first accommodating cavity 111 with the external environment. The heat dissipation inner duct 121 serves to provide a passage through which air flows so that the air flows through the entire motor and takes away heat emitted from the motor.

The motor top cover heat dissipation ribs 471 increase the contact area between the first housing 401 and the wind flow, which is beneficial to improving the heat dissipation effect of the first housing 401.

In some embodiments, motor top cover heatsink 471 may be an aluminum alloy material. In other embodiments, the motor top cover heat sink 471 may also be a pure copper material.

It is understood that the material, thickness, number or length of the motor top cover heat dissipation ribs 471 may be varied according to design requirements. For example, the motor top cover heat sink rib may be 2mm thick and 6mm high.

In some embodiments, the motor top cover cooling ribs 471 may be arranged in a fan type rotary radiation manner with the center point of the motor top cover 461 as the center, and a part of the motor top cover cooling ribs 471 are long cooling ribs with equal length, and the other part of the motor top cover cooling ribs 471 are short cooling ribs with half length, and the short cooling ribs are equidistantly arranged between the gaps of the long cooling ribs.

The cooling fan 625 drives air flow into the first housing 601, passes through the cooling inner air duct 621, and flows out from the bottom of the first housing 601.
