[0032] To address the problems in the background technology, this utility model proposes an electric heater with a heat dissipation structure, comprising:

[0033] Electric heater body 1;

[0034] Base 2, which is connected to the bottom of the electric heater body 1, and has a built-in cooling fan 4;

[0035] Top component 3, the top component 3 having a first connecting part 31, and connected to the electric heater body 1 through the first connecting part 31;

[0036] The first connecting part 31 is provided with a first array of heat dissipation holes 311 around its periphery, and the electric heater body 1 has a through hole 14 inside, which enables the air outlet direction of the cooling fan 4 to form a convection channel with the first array of heat dissipation holes 311.

[0037] Combined with reference Figures 1 to 3 As shown, in this embodiment, the heater body 1, as the core part of the entire heater, contains a heating element that generates heat to provide warmth during operation. A base 2 is connected to the bottom of the heater body 1. The base 2 integrates a control module for driving and controlling the operation of the heater body 1 or switching between different operating modes. To prevent the internal temperature of the heater body 1 from becoming too high, a cooling fan 4 is built into the base 2. The air inlet side of the cooling fan 4 faces the mounting cavity inside the base 2, and air inlets are provided on the periphery of the base 2's outer shell, while the air outlet side of the fan faces upwards towards the heater body 1. By drawing in surrounding air, the fan blades accelerate airflow, thereby improving heat dissipation efficiency.

[0038] In addition, a top component 3 is provided above the main body 1 of the electric heater. The top component 3 has a first connecting part 31 that is adapted to the overall shape of the main body 1 of the electric heater. The connecting part is connected to the top of the main body 1 of the electric heater, and multiple heat dissipation holes are evenly arranged around the connecting part, forming a first array-type heat dissipation hole group 311. This design helps to promote the exhaust of hot air, thereby enhancing airflow and further improving the heat dissipation effect. A through hole 14 is provided inside the main body 1 of the electric heater. The through hole 14 extends from the bottom to the top of the main body 1 of the electric heater, forming a vertically connected channel. This through hole 14 makes the bottom and top of the main body 1 open, respectively, and connected to the base 2 and the top component 3, thereby forming a vertically connected convection channel inside the main body 1 of the electric heater. This convection channel is connected to the base 2 and the first connecting part 31, ensuring the continuity of airflow.

[0039] When the cooling fan 4 is started, external air is sucked in through the base 2 or other air inlets of the device, the fan blades rotate to accelerate air flow, and push the air to flow to the air outlet side. The heat generated by the heating element in the electric heater body 1 will cause the air temperature to rise, and the airflow brought by the fan will help to take away these hot air and exhaust through the array of cooling holes. Due to the continuous airflow, the hot air is quickly taken away, thereby effectively avoiding the overheating phenomenon of the electric heater.

[0040] In a possible implementation, the top of the base 2 is formed with a wind guide 22 connected to the through hole 14, and the bottom of the wind guide 22 is fixedly connected with a support frame 5, and the support frame 5 has a plurality of connecting holes 51, and the cooling fan 4 is fixedly installed on the support frame 5 by penetrating the connecting holes 51 with fasteners.

[0041] In combination with reference to Figure 2 and Figure 3 In this embodiment, the top of the base 2 extends upward to form a wind guide 22, which is partially inserted into the through hole 14 inside the electric heater body 1 and tightly connected and communicated with the through hole 14, aiming to guide the air sucked by the fan to flow in a specific direction, thereby effectively concentrating the airflow and enhancing heat exchange. Through the connection with the through hole 14, the wind guide 22 ensures that the cold air entering from the fan can directly flow to the heating element or the heat area inside the device, thereby improving the efficiency of heat removal. The bottom of the wind guide 22 is fixedly connected with a support frame 5, and the main function of the support frame 5 is to provide a stable mounting position for the cooling fan 4 and ensure the stable operation of the fan. The support frame 5 is provided with a plurality of connecting holes 51, and fasteners such as screws and nuts can be used to firmly install the cooling fan 4 on the support frame 5, so as to ensure that the fan will not be displaced or loose during operation, and to ensure the reliability of the device operation.

[0042] In a possible implementation, the top of the base 2 has a second connecting part 21, and the second connecting part 21 is connected with the bottom of the electric heater body 1, and the second connecting part 21 is circumferentially provided with a second array of cooling holes 211.

Each connecting part is fixedly connected with the electric heater body 1 through thread, buckle, plug-in and the like, so as to ensure that each part of the electric heater can be firmly combined. The second connecting part 21 is circumferentially provided with a second array of cooling holes 211, which can increase the air flow area between the inside and outside, improve the flowability of the air, and thereby optimize the cooling effect.
