Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] The inverter water faucet is a key component for connecting the water circuit. Currently, the most common water faucet sealing design is usually located on the side of the inverter housing. As inverter application requirements increase, the requirements for the main body space size are becoming increasingly stringent. At the same time, the increase in power also increases the heat dissipation requirements of the inverter. The conventional water faucet sealing design is usually located on the side of the inverter housing; however, with the changing market demand, this design is no longer able to meet the new design requirements.

[0029] By placing the water nozzle above the inverter, the utility model can better utilize the space inside the inverter and avoid interference with other components, which helps to improve the overall layout and installation flexibility of the system; bubbles may be generated during the circulation of the coolant, and the water nozzle is placed above, so that the bubbles are more easily discharged along with the coolant, preventing bubbles from accumulating in the system and affecting the cooling effect.

[0030] Example 1

[0031] like Figure 1-Figure 3 As shown, an automobile inverter water faucet device with a sealed structure is shown. The inverter includes an inverter cover 1, an inverter housing 2, a water channel and a water faucet 5. The water channel is located on the inverter housing 2. The inverter cover 1 is fixed to the inverter housing 2. The water faucet 5 penetrates the inverter cover 1 and is connected to the inverter cover 1. The water faucet 5 is provided with a sealing structure and cooperates with the water channel.

[0032] In this embodiment, the inverter water nozzle's primary function is to connect the inverter's internal water cooling system. Coolant enters the inverter through nozzle 5, absorbing heat generated during operation. It is then discharged through the nozzle, removing the heat and achieving a cooling effect. Positioning nozzle 5 above the inverter may cause bubbles to form during coolant circulation. This placement allows bubbles to be more easily expelled along with the coolant, preventing them from accumulating within the system and impacting cooling effectiveness. Positioning the nozzle above allows for better utilization of space within the inverter, avoiding interference with other components and improving overall system layout and installation flexibility.

[0033] The water channel is provided with an inverter housing water channel outlet boss 7, and the sealing structure includes a water outlet sealing ring 4 and a convex ring 6 arranged on the water nozzle 5. The water outlet sealing ring 4 is located on the upper and lower sides of the convex ring 6 and cooperates with the inverter housing water channel outlet boss 7.

[0034] The convex ring 6 is located on a side close to the inverter housing 2 .

[0035] The sealing structure further includes a water inlet sealing ring 8 . The inverter upper cover 1 is provided with an inverter upper cover water channel groove 9 . The water inlet sealing ring 8 is located in the inverter upper cover water channel groove 9 .

[0036] The sealing structure further includes a water spout groove 3 , which is arranged corresponding to the water channel groove 9 on the inverter upper cover.

[0037] The convex ring 6 is located on a side close to the inverter housing 2 .

[0038] The water faucet 5 is provided with a water faucet groove 3 , and the water faucet groove 3 is arranged corresponding to the water channel groove 9 of the inverter upper cover.

[0039] The water faucet groove 3 and the inverter upper cover water channel groove 9 are annular.

[0040] In this embodiment, a convex ring 6 is provided on the faucet 5. As a result, recessed areas appear on the faucet wall above and below the convex ring 6. The water outlet seal ring 4 is placed within this recessed area, and the faucet 5 is coaxially connected to the waterway. The bottommost water outlet seal ring 4 engages with the inverter housing waterway outlet boss 7, securing the water outlet seal ring 4. By providing the water inlet seal ring 8 and the water outlet seal ring 4, a double seal design is adopted, greatly improving the reliability of the sealing structure and effectively preventing leakage and external contaminants from entering the device. This reduces wear and corrosion on the device, thereby extending its service life, reducing the frequency of leakage and failure, and reducing the cost of maintaining and replacing seals. The convex ring 6 is 4.7 mm wide and 2.5 mm thick; the inverter cover waterway groove 9 is 4 mm wide and 3.5 mm deep.

[0041] At the same time, the faucet groove 3 and the inverter cover water channel groove 9 are arranged correspondingly to form a space, and the water inlet sealing ring 8 is placed in the formed space to complete the sealing.

[0042] The water nozzle 5 is connected to the inverter upper cover 1 through bolts 10.

[0043] The longitudinal section of the water outlet sealing ring 4 is O-shaped, and the longitudinal section of the water inlet sealing ring 8 is rectangular.

[0044] The water outlet sealing ring 4 and the water inlet sealing ring 8 are made of EPDM.

[0045] In this embodiment, the sealing rings are made of EPDM (Ethylene Propylene Diene Monomer), which exhibits excellent weather resistance, heat resistance, chemical resistance, electrical insulation, elasticity, and flexibility. The dimensions of the water inlet sealing ring 8 are: 40.5mm inner diameter, 45.5mm outer diameter, and 2.5x5mm cross-sectional diameter. The dimensions of the water outlet sealing ring 4 are: 17mm inner diameter, 24mm outer diameter, and 3.5mm cross-sectional diameter.

[0046] The water nozzle 5 is coaxial with the water channel.

[0047] In this embodiment, two independent sealing layers are designed at the water inlet and outlet to ensure effective sealing. The outlet seal 4 is designed as the primary sealing layer, directly contacting the coolant and primarily responsible for preventing coolant leakage. The inlet seal 8 is designed as a secondary sealing layer, providing additional protection after the primary sealing layer. If the primary sealing layer fails, the secondary sealing layer can prevent coolant from leaking out.

[0048] Poor sealing can lead to a series of consequences. 1. Equipment overheating: The main function of the coolant is to absorb and carry away the heat generated by the inverter during operation. If the coolant leaks, the cooling effect will be greatly reduced, causing the internal temperature of the inverter to rise. This may cause the equipment to overheat, affecting its normal operation, or even causing equipment damage. 2. Electrical failure: Coolant leakage may enter the electrical part of the inverter, causing a short circuit or other electrical failure. This will not only affect the performance of the inverter, but may also pose a safety hazard. 3. Corrosion and damage: Leaked coolant may corrode the metal parts of the inverter, resulting in a decrease in the mechanical strength of the equipment and increased maintenance and replacement costs. 4. Environmental pollution: If the coolant contains harmful chemicals, leakage may cause environmental pollution, especially in large-scale applications. 5. Reduced system efficiency: Coolant leakage will cause the efficiency of the inverter's cooling system to decrease, which in turn affects the operating efficiency and stability of the entire system.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
