Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging piles, in particular to an air-cooled high-power transformer module. Background Art

[0002] A charging pile is a device that provides electric vehicles with energy replenishment. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall, installed in public buildings and parking lots in residential areas, and can charge various types of electric vehicles according to the voltage and current. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging operations and print cost data. The charging pile display can display data such as charging capacity, cost, and charging time.

[0003] However, the existing new energy vehicle charging piles tend to heat up quickly and need to dissipate heat in time. Considering the cost and potential risks of water cooling, air cooling is generally used. However, air cooling has high requirements on the structure of the module. Since the traditional charging module does not separate the two sets of coils, the heat dissipation effect is poor, which affects the heat dissipation efficiency and cannot meet the use requirements. Therefore, an air-cooled high-power transformer module is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an air-cooled high-power transformer module, which has the advantages of strong practicality and air cooling, and solves the problem that the traditional charging module does not separate the two sets of coils, resulting in poor heat dissipation effect and affecting the heat dissipation efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air-cooled high-power transformer module, comprising a module body and two groups of coils arranged in the module body, the left and right inner walls of the module body are both equipped with cable ties for limiting the two groups of coils, a magnetic column is installed between the two cable ties, and the two groups of coils are separated by the two cable ties and the magnetic column to form a ventilation and heat dissipation channel, thereby achieving air cooling, and a filtering structure is arranged in the heat dissipation channel;

[0006] The filtering structure comprises a frame, a ventilating opening used in conjunction with the heat dissipation channel is provided inside the frame, and a filter screen is embedded inside the ventilating opening;

[0007] The frame is provided with a mounting mechanism inside, and the mounting mechanism comprises a dual-axis micro motor arranged inside the frame, a lead screw, an adjustment sleeve threadedly connected to one end of the lead screw, and an abutment block fixedly mounted on the other end of the adjustment sleeve.

[0008] Furthermore, two symmetrically arranged installation grooves are provided inside the frame, and receiving openings communicating with the installation grooves are provided on both upper and lower sides of the frame.

[0009] Furthermore, the number of lead screws, adjustment sleeves and abutment blocks in the installation mechanism is four, and the four lead screws are symmetrically arranged in two installation grooves in a group of two. The dual-axis micro motor is fixedly installed in the left installation groove, and the opposite ends of the two lead screws on the left are respectively fixed to the two output shafts of the dual-axis micro motor.

[0010] Furthermore, the threads on the two left screws and the two right screws are arranged in opposite directions, a linkage structure is arranged between the left and right screws, and the linkage structure includes a transmission wheel fixedly installed between the left and right screws, and a belt is connected between the two transmission wheels.

[0011] Furthermore, a communicating opening is provided between the left and right installation grooves, and the belt extends into the two installation grooves through the opening.

[0012] Furthermore, four sliding grooves are provided inside the two installation grooves, and sliding rods slidably connected to the sliding grooves are installed on the right sides of the four adjustment sleeves.

[0013] Compared with the prior art, the utility model provides an air-cooled high-power transformer module, which has the following beneficial effects:

[0014] 1. The air-cooled high-power transformer module has a simple and convenient structure. By separating the two sets of coils, a ventilation and heat dissipation channel is formed to achieve air cooling, thereby achieving the advantages of strong practicality and air cooling. It solves the problem that the traditional charging module does not separate the two sets of coils, resulting in poor heat dissipation effect and affecting the heat dissipation efficiency.

[0015] 2. The air-cooled high-power transformer module realizes the synchronous rotation of four lead screws by starting the dual-axis micro motor, cooperating with the transmission wheel and the belt. Since the threads on the lead screws are opposite, the four adjustment sleeves are displaced apart. At this time, the four abutment blocks are abutted against the upper and lower sides of the heat dissipation channel to fix the filter screen, filter through the filter screen, reduce the entry of impurities, and improve the protection of the two sets of coils.
