Description

Technical Field

[0001] This utility model relates to the field of electric furnace technology, specifically a heat dissipation structure for an electric furnace. Background Technology

[0002] Existing electric furnaces mainly consist of a bottom shell and a panel mounted on the bottom shell. The bottom shell and panel together form the furnace's housing cavity, which contains heating elements and a main control board. During operation, the heating elements on the magnetic coil and main control board generate a large amount of heat. In addition, the cookware radiates heat into the furnace through the panel, resulting in a relatively high internal temperature. Therefore, an axial fan and air duct are also installed in the housing cavity to blow cool air towards the heating components such as the main control board and magnetic coil, and then exhaust it through the air outlet. However, the axial fan draws air in and out axially, and the airflow is directed directly towards the panel and bottom shell, which can easily lead to scattered and turbulent airflow, increasing wind resistance and affecting the airflow volume and air pressure of the air duct, ultimately resulting in poor heat dissipation.

[0003] Chinese utility model patent No. 200720068801.7 discloses a heat dissipation system for an induction cooker. This heat dissipation system uses a diamond-shaped air duct to concentrate the horizontal airflow of the axial fan onto the motherboard. Although it can achieve a certain heat dissipation effect, it cannot fundamentally solve the problem of scattered and turbulent axial airflow when the axial fan is working.

[0004] Therefore, further improvements are necessary. Utility Model Content
