Problems solved by technology

[0004]The traditional water channel sealing method is to set an O-shaped rubber ring in the product sealing area, such as Figure 3, 4, when the box body and the cover plate are assembled with bolts tightened, the O-shaped rubber ring is squeezed and deformed, and completely fills the entire sealing area to achieve the sealing effect, but in Under the double pressure of the internal cooling water and the cover plate, the rubber ring of the outgoing line is often broken or aging and fails during the installation test, resulting in water leakage, and the internal electronic components are short-circuited and burned

Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0044] a kind of like Figure 1-Figure 6 The shown new energy vehicle charger water channel sealing process is used to seal the charger box 100 and the water channel cover plate 200 and make the water channel 300 a sealed circuit, which includes the following steps,

[0045] S1. Machining. A sol tank 400 is processed along the water channel 300 on the mating surface of the water channel cover plate 200 of the charger case 100. The sol tank 400 is located at the root of the water channel 300 and communicates with it. The bottom side of the sol tank 400 has a A C-angle structure 401 inclined in the direction of the waterway 300, the C-angle structure 401 is a transitional structure with a slope or an arc;

[0046] S2. Glue dispensing, in a constant temperature and humidity environment, continuously dispense sealant 500 in the sol tank 400 ...

Abstract

The invention discloses a new energy automobile charger water channel sealing process and structure. Sealing of a charger water channel is achieved through the steps of machining, dispensing, assembling, curing, testing a leakage through a sol groove and a C angle structure, enabling a charger box body and water to be sealed through a sealant and the like, a sealing structure between the charger box body and a water channel cover plate is innovatively designed, and sealing is formed between the root of the water channel and the water channel cover plate. According to the new energy automobile charger water channel sealing process and structure,a traditional O-shaped rubber ring sealing process is replaced, the sealing effect is stable, the service life is long, and the situation that due to fracture or aging failure of a traditional sealing ring, water leakage is caused, and internal electronic elements are short-circuited and burnt is avoided.

Description

technical field [0001] The invention relates to a water channel sealing process and structure of a new energy vehicle charger, belonging to the technical field of new energy vehicle charging. Background technique [0002] The main function of the on-board charger is to convert the alternating current output by the charging pile into the direct current required by the new energy electric vehicle, and determine the charging power and efficiency of the electric vehicle. The assembly product is mainly composed of a circuit board, a box, a cover, and a nozzle interface and so on, such as figure 1 As shown, but because there are many internal electronic components installed in the assembly and the working temperature is high, the box needs to be equipped with a high-pressure water channel structure to cool down the interior to prevent the internal circuit from being burned due to excessive temperature. [0003] In order to ensure the normal operation of the box in the high-temper...
