[0026] The secondary heat dissipation component 6 includes a second fan 60 and a third fan 61. The second fan 60 is installed on one side of the protective shell 1 and is used for internal heat dissipation of the protective shell 1. The third fan 61 is located on the opposite side of the second fan 60 and is used to assist the operation of the second fan 60.
[0027] The outer surface of the protective shell 1 is in contact with the inner wall of the protective shell 1. The circuit board 2 and the power interface 3 are electrically connected to each other. The circuit board 2 and the high surge device 4 are electrically connected to each other. The top surface of the mounting shell 50 and the bottom surface of the circuit board 2 are fixedly connected to each other.
[0028] When the power adapter starts working, the high surge device 4 mounting housing 50 and the circuit board 2 mounting housing 50 generate some heat. The main heat dissipation assembly 5 mounting housing 50 then begins to operate: the gel box 51 mounting housing 50 makes close contact with the bottom surface of the circuit board 2 mounting housing 50, absorbing and conducting heat to the thermally conductive copper plate 52 mounting housing 50. The thermally conductive copper plate 52 mounting housing 50 transfers the heat to the heat sink 53 mounting housing 50, and the fins 54 mounting housing 50 on the heat sink 53 mounting housing 50 increase the heat dissipation area and improve heat dissipation efficiency.
[0029] Example 2
[0030] Based on the above embodiment 1, please refer to Figures 4-6 The top surface of the gel box 51 is in close contact with the bottom surface of the circuit board 2, the outer surface of the gel box 51 is in contact with the upper part of the inner wall of the mounting shell 50, and the bottom surface of the gel box 51 is fixedly connected to the top surface of the heat-conducting copper plate 52. The gel box 51 is used to conduct the heat of the circuit board 2 to the heat-conducting copper plate 52.
[0031] The bottom surface of the thermally conductive copper plate 52 is fixedly connected to the top surface of the heat sink 53. There are several heat sinks 53. Several fins 54 are fixedly installed on both sides of the heat sinks 53 at a 45° angle. The fins 54 are used to increase the contact area between the heat sink 53 and the heat dissipation air. Three first fans 55 are fixedly installed on one side of the mounting shell 50. The first fans 55 are used for ventilation and heat dissipation inside the mounting shell 50.
[0032] The connecting plate 56 is disposed on the opposite side of the first fan 55 and is fixedly connected to the mounting shell 50. The inner wall of the connecting plate 56 is fixedly connected to the connecting plate 56, and the outer surface of the connecting plate 56 is fixedly connected to the inner wall of the protective shell 1. The inner wall of the vent 57 is fixedly installed with a filter screen 58 for ventilation and heat dissipation in conjunction with the first fan 55.
[0033] There are three second fans 60, which are fixedly installed at equal intervals on one side of the inner wall of the protective shell 1. The outer surface of the third fan 61 is fixedly connected to one side of the inner wall of the protective shell 1.
[0034] The first fan 55, mounted on the housing 50, starts up, drawing in cool outside air through the vent 57. After being filtered by the filter screen 58, the air is blown onto the heat sink 53 and fin 54, carrying away heat, and then exhausted through the vent on the other side of the connecting plate 56. Simultaneously, the second fan 60 and the third fan 61 in the secondary heat dissipation assembly 6 also begin operating, further promoting airflow within the protective housing 1 and enhancing the heat dissipation effect.
[0035] The working principle and usage of this utility model are as follows: Place the surge protection power adapter in a suitable location and ensure it is stable.

The circuitry on the circuit board 2 mounting housing 50 and the surge protection device 4 mounting housing 50 operate normally through internal electrical connection, protecting the equipment from damage caused by high surge voltages.
[0036] Start-up and Heat Dissipation: When the power adapter starts working, the high surge device 4 mounting shell 50 and the circuit board 2 mounting shell 50 generate a certain amount of heat. The main heat dissipation assembly 5 mounting shell 50 starts operating: the gel box 51 mounting shell 50 is in close contact with the bottom surface of the circuit board 2 mounting shell 50, absorbing and conducting heat to the heat-conducting copper plate 52 mounting shell 50. The heat-conducting copper plate 52 mounting shell 50 transfers heat to the heat sink 53 mounting shell 50, and the fins 54 mounting shell 50 on the heat sink 53 mounting shell 50 expand the heat dissipation area and improve heat dissipation efficiency. The first fan 55 mounting shell 50 starts, drawing in external cold air through the vent 57 mounting shell 50, filtering it through the filter screen 58 mounting shell 50, and blowing it towards the heat sink 53 mounting shell 50 and the fins 54 mounting shell 50, carrying away heat, and exhausting hot air through the vent on the other side of the connecting plate 56 mounting shell 50. At the same time, the second fan 60 and the third fan 61 in the secondary heat dissipation assembly 6 mounting housing 50 also start to operate, further promoting air circulation inside the protective housing 1 mounting housing 50 and enhancing the heat dissipation effect.
[0037] Continuous monitoring and maintenance: During the operation of the power adapter, continuously monitor its working status and temperature. Regularly clean the filter screen 58 mounting housing 50 to prevent dust from clogging the ventilation openings and affecting heat dissipation. Regularly check the operation of fans 55, 60, and 61 mounting housing 50 to ensure they are working properly.
