As the preferred embodiment of the utility model, the substrate is equipped with ventilation hole, and the ventilation hole is located at the frequency conversion The side of device electronic device and the close radiator.
As the preferred embodiment of the utility model, the diameter of the flow-guiding mouth is 1 centimetre or less.
By adopting the above technical scheme, the beneficial of the utility model is: setting radiator and second chamber are provided with ditch It is formed with heat dissipation channel between the side wall of slot, by forming annular wind between the lateral wall of annular slab and the intracavity sidewall of cabinet The wind in road, fan blowout passes through air flow guiding chamber, then after entering annular passage by flow-guiding mouth, under the action of annular passage It generates eddy flow and the inner cavity through cabinet is sent, which can form negative pressure in the inner cavity of cabinet, so that in heat dissipation channel Air is flowed toward the inner cavity of cabinet, and heat is taken out of;Again since fan is located at hull outside, dissipating for heat dissipation wind channel will not be blocked Heat.Therefore it is scattered to provide a kind of frequency converter that heat dissipation effect is relatively preferable and relatively low air duct cleaning and maintenance frequency for the utility model Heat structure.
Further, a part of heat can be sucked out by ventilation hole from first chamber by ventilation hole being equipped on substrate.
Further, since the diameter of flow-guiding mouth is generally 1 centimetre hereinafter, the entire annular cross-sectional area of annular passage is got over Small, flow-guiding mouth is narrower;Such narrow air passage outlet design, is to make air-flow diffuse air-flow from the low speed of wide area and be transformed into high speed Jet-stream wind and design;The high-speed flow ejected from circular passage forms an annular high-speed flow, such high-speed loop The flowing of shape air-flow is moved up the hollow space air for making cabinet, by violent band so as to form the wide area in heat dissipation wind channel Cooling air-flow.To realize the heat dissipation of frequency converter.
