Description

A direct heat dissipation type high-power commercial induction cooker

technical field

The utility model relates to an electromagnetic cooker, in particular to a direct heat dissipation type high-power commercial electromagnetic cooker.

Background technique

At present, only low-power household induction cookers below 2.5KW adopt an integrated structure with bottom blowing, that is, a cooling fan at the bottom simultaneously dissipates heat for the electronic components and electromagnetic induction coils in the host, while high-power commercial induction cookers generally use Two independent heat dissipation fans respectively dissipate heat from the host and the induction coil. This structure needs to install multiple heat dissipation fans for heat dissipation, which increases the power loss of the induction cooker. There are also a small number of integrated high-power induction cookers that are cooled by a cooling fan, but the cooling fan is installed between the host and the electromagnetic induction coil, and the cooling fan is in the working mode of half exhaust and half blast. The advantages of this method are: It is conducive to the air intake of the air duct, which is convenient for the host to dissipate heat, but it is not conducive to the maintenance and replacement of the cooling fan.
