[0019] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0020] The water-cooled inverter of this embodiment is as follows Figures 1 to 5 As shown, it includes a shell 15, and the shell includes the upper cover body 2 and the water-cooled bottom shell body 1. The upper cover body is fixedly connected to the water-cooled bottom shell body. The upper cover body is provided with a main drive board module 3, a water-cooled heat sink 8, and a sealing gasket 5. The water-cooled heat sink is made of aluminum alloy material. The aluminum alloy material helps to quickly transfer heat to the water-cooled chamber, thereby ensuring that the main drive board module operates at a low temperature, and then the inverter temperature is water-cooled and dissipated. The water-cooled bottom shell body includes a water inlet chamber 10, a water-cooled chamber 11, and a water outlet chamber 12. The water outlet chamber is provided with a water pressure sensor 9, and the water pressure sensor transmits the water pressure of the water outlet chamber to the main drive board module for control. The sealing gasket is provided between the water-cooled chamber and the water-cooled heat sink, and the sealing gasket isolates the cooling chamber from the main drive board module. The main drive board module is provided on the water-cooled heat sink.

[0021] The water-cooling chamber in this embodiment is also equipped with a one-way plug 6, which is equipped with a sealing ring 13. The one-way plug is located at the opening 14 of the water inlet chamber and is used to prevent water from flowing back into the water inlet chamber. The water-cooling chamber is also equipped with a plug stopper 7, which prevents the one-way plug from escaping the water inlet chamber when flushed open by water. The water-cooling chamber is also equipped with a water baffle 4, which allows water to pass closely against the water-cooled radiator.

[0022] This embodiment works as Figure 1 、 2 As shown in 4 and 5, after water enters the water inlet cavity, the one-way plug is flushed from the orifice so that the water enters the water cooling chamber. The water in the water cooling chamber cools the main drive board module and then enters the water outlet cavity. Figure 3 As shown, water no longer enters the water inlet chamber, and the one-way plug is affected by gravity and falls back to the orifice to prevent water from flowing back into the water inlet chamber.

[0023] The frequency converter of this embodiment dissipates heat through water cooling, which not only stabilizes the heat dissipation but also further achieves the purpose of miniaturization of the frequency converter because the fan is removed.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
