AI Technical Summary
Existing frequency inverters have problems such as inability to dissipate heat after the fan is damaged and large size, which makes it impossible to achieve miniaturization.
A water-cooled heat dissipation system is adopted, including a water-cooled heat dissipation plate, an inlet chamber, an outlet chamber, and a sealing gasket. It utilizes the high thermal conductivity of aluminum alloy material for heat dissipation and prevents coolant backflow through one-way plugs and sealing rings to achieve stable heat dissipation.
Stable heat dissipation was achieved, and the fan was eliminated, thus miniaturizing the frequency converter.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0020] The water-cooled frequency converter in this embodiment is as follows: Figures 1 to 5 As shown, the system includes a housing 15, which comprises an upper cover 2 and a water-cooled bottom housing 1, with the upper cover and the water-cooled bottom housing fixedly connected. The upper cover houses 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, which helps to quickly transfer heat to the water-cooling chamber, ensuring the main drive board module operates at low temperatures, thus achieving water-cooled heat dissipation for the inverter. The water-cooled bottom housing includes a water inlet chamber 10, a water-cooling chamber 11, and a water outlet chamber 12. A water pressure sensor 9 is installed on the water outlet chamber, transmitting the water pressure from the outlet chamber to the main drive board module for control. The sealing gasket is located between the water-cooling chamber and the water-cooled heat sink, isolating the cooling chamber from the main drive board module. The main drive board module is mounted on the water-cooled heat sink.
[0021] The water cooling chamber is further provided with a one-way plug 6, which is provided with a sealing ring 13 and is located on the orifice 14 of the water inlet cavity, and the one-way plug is used to prevent the water in the cooling chamber from flowing back to the water inlet cavity. The water cooling chamber is further provided with a plug limiting block 7, which is used to prevent the one-way plug from being separated from the water inlet cavity when the one-way plug is washed away by the water. The water cooling chamber is further provided with a water baffle 4, which is used to make the water pass through the water cooling heat sink.
[0022] When the embodiment works, as shown in Figure 1 , When the embodiment works, as shown in 2 , 4, 5, the water enters the water inlet cavity, the one-way plug is washed away from the orifice, and then the water enters the water cooling chamber. After the water in the water cooling chamber cools and heats the main drive plate module, the water enters the water outlet cavity. Figure 3 When the embodiment does not work, as shown in , When the embodiment does not work, as shown in , the water no longer enters the water inlet cavity, and the one-way plug is affected by gravity and falls back to the orifice to prevent the water from flowing back to the water inlet cavity.
[0023] The frequency converter of the embodiment is cooled by water, which is not only stable in heat dissipation, but also can further achieve the purpose of miniaturization of the frequency converter because the fan is removed.
[0024] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
