[0003] CN202420072873.2 and CN201721089905.6 describe inverters primarily consisting of a housing and a PCBA (Printed Circuit Board Assembly) mounted within the housing. The PCBA incorporates integrated connectors. The housing typically consists of an upper and lower housing, forming a mounting cavity between the two. The PCBA is secured within the cavity. Heat generated by the inverter is caused by internal losses. The main circuit accounts for approximately 98% of the losses in the inverter, while the control circuit contributes 2%. To ensure normal and reliable operation of the inverter, heat dissipation must be managed. In the prior art, heat sinks and fans are mounted on the circuit board and then within the cavity. This increases the size of the housing. Furthermore, the heat cannot be fully dissipated due to the obstruction of the housing, impacting the inverter's performance. To address this issue, a split-type inverter has been designed. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a split-type inverter to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A split-type inverter includes a housing and a PCBA board disposed inside the housing, and further includes a heat dissipation base. The housing is connected to the heat dissipation base. A mounting cavity for mounting the PCBA board is defined on a surface of the heat dissipation base. The inner sidewall of the mounting cavity is provided with a corrugated heat-conducting surface for increasing the heat-conducting area.

[0007] By adopting the above structural design, the split-type inverter consists of a housing, a heat sink base, and a PCBA board. The PCBA board is installed in a mounting cavity on the heat sink base. The inner side wall of the mounting cavity is provided with a corrugated heat-conducting surface. The heat generated during operation of the PCBA board can be transferred to the heat sink base through the corrugated heat-conducting surface and the mounting cavity, and then dissipated to the outside through the heat sink base, thereby improving the heat dissipation effect of the inverter and avoiding failures caused by heat accumulation. At the same time, the housing and the heat sink base are installed independently, which can greatly reduce the difficulty of disassembling the inverter and improve the maintenance efficiency of the inverter.

[0008] Furthermore, the housing is detachably connected to the heat dissipation base;

[0009] The bottom of the shell is provided with four buckles, and the buckles are elastic;

[0010] Slide grooves for connecting buckles are provided on both sides of the top of the heat dissipation base, and a clamping portion that can be embedded in the shell is provided on the top of the slide groove.

[0011] By adopting the above structural design, the shell can be detachably connected to the heat dissipation base, which makes it easy to disassemble the shell and maintain the PCBA board on the heat dissipation base.

[0012] Furthermore, a fan is included, and a mounting groove for mounting the fan is provided at the lower end of the heat dissipation base.

[0013] Furthermore, a plurality of outwardly protruding heat dissipation fins are provided on a side of the heat dissipation base away from the shell, and the air outlet of the fan is aligned with the heat dissipation fins.

[0014] Furthermore, the surface of the heat dissipation fin is provided with a corrugated heat dissipation surface for increasing the heat dissipation area.

[0015] By adopting the above-mentioned structural design, under the obstruction of the heat dissipation base, the air driven by the fan during operation only circulates through the heat dissipation fins, while ensuring the heat dissipation efficiency of the heat dissipation base, the amount of dust entering the shell is reduced. The surface of the heat dissipation fins is provided with a corrugated heat dissipation surface, which can improve the heat dissipation efficiency.

[0016] Furthermore, a plurality of heat dissipation holes connected to the outside are evenly arranged on the outer side of the shell.

[0017] Furthermore, four corners of the bottom of the heat dissipation base are provided with mounting holes through which screws can pass.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This split-type inverter consists of a housing, a heat sink, and a PCBA. The PCBA is installed in a mounting cavity on the heat sink. The inner wall of the mounting cavity is provided with a corrugated heat-conducting surface. Heat generated during operation of the PCBA is transferred to the heat sink through the corrugated heat-conducting surface and the mounting cavity. The heat is then dissipated to the outside through the heat sink, improving the heat dissipation effect of the inverter and avoiding failures caused by heat accumulation. At the same time, the housing and heat sink are installed independently, which can greatly simplify the disassembly of the inverter and improve the maintenance efficiency of the inverter.

[0033] Example 1:

[0034] like Figure 1-5 As shown, the present invention provides a split-type inverter, comprising a housing 1 and a PCBA board disposed within the housing 1, and further comprising a heat sink base 2. The housing 1 is connected to the heat sink base 2, and a surface of the heat sink base 2 is provided with a mounting cavity 204 for mounting the PCBA board. The inner sidewall of the mounting cavity 204 is provided with a corrugated heat conducting surface 2041 for increasing the heat conduction area. By adopting the above structural design, the split-type inverter is composed of the housing 1, the heat sink base 2, and the PCBA board. The PCBA board is mounted in the mounting cavity 204 on the heat sink base 2, and the inner sidewall of the mounting cavity 204 is provided with a corrugated heat conducting surface 2041. Heat generated during operation of the PCBA board can be transferred to the heat sink base through the corrugated heat conducting surface 2041 and the mounting cavity 204, and then dissipated to the outside through the heat sink base 2, thereby improving the heat dissipation effect of the inverter and avoiding malfunctions caused by heat accumulation. At the same time, the housing 1 and the heat sink base 2 are installed independently, which can significantly reduce the difficulty of disassembling the inverter and improve the maintenance efficiency of the inverter.

[0035] In this embodiment, the housing 1 is detachably connected to the heat sink base 2. Four elastic clips 102 are provided on the bottom of the housing 1. Slide grooves 202 for connecting the clips 102 are provided on both sides of the top of the heat sink base 2. The tops of the slide grooves 202 are provided with engaging portions 203 that can be inserted into the housing 1. This structural design allows the housing 1 to be detachably connected to the heat sink base 2, making it easy to disassemble the housing 1 and access the PCBA board on the heat sink base 2.

[0036] In this embodiment, a fan 3 is also included, and a mounting slot 205 for mounting the fan 3 is provided at the lower end of the heat dissipation base 2. A plurality of outwardly protruding heat dissipation fins 206 are provided on the side of the heat dissipation base 2 away from the housing 1, and the air outlet of the fan 3 is aligned with the heat dissipation fins 206. The surface of the heat dissipation fins 206 is provided with a corrugated heat dissipation surface 2061 to increase the heat dissipation area. By adopting the above-mentioned structural design, the air driven by the fan 3 during operation, blocked by the heat dissipation base 2, circulates only through the heat dissipation fins 206. While ensuring the heat dissipation efficiency of the heat dissipation base 2, the amount of dust entering the housing 1 is reduced. The corrugated heat dissipation surface 2061 provided on the surface of the heat dissipation fins 206 can improve the heat dissipation efficiency.

[0037] In this embodiment, the outer side of the housing 1 is evenly distributed with a plurality of heat dissipation holes 101 that are connected to the outside. The provision of heat dissipation holes 101 allows external air to enter the interior of the housing 1, further improving the heat dissipation effect. The bottom corners of the heat dissipation base 2 are provided with mounting holes 201 for screws to pass through.

[0038] Working principle: The split-type inverter consists of a shell 1, a heat dissipation base 2 and a PCBA board. The PCBA board is installed in the installation cavity 204 on the heat dissipation base 2. The inner wall of the installation cavity 204 is provided with a corrugated heat-conducting surface 2041, so that the heat generated during the operation of the PCBA board can be transferred to the heat dissipation base through the corrugated heat-conducting surface 2041 and the installation cavity 204, and dissipated to the outside through the heat dissipation base 2, thereby improving the heat dissipation effect of the inverter and avoiding failures caused by heat accumulation; at the same time, the shell 1 and the heat dissipation base 2 are installed independently, which can greatly reduce the difficulty of disassembling the inverter and improve the maintenance efficiency of the inverter.
