Body, electromagnetic wire coil, wiring board and radiator fan, described electromagnetic wire coil is that spill is arranged, and wiring board is provided with heat release device, housing
Including shell and drain pan, drain pan is provided with the air inlet corresponding with radiator fan, and described housing also includes setting inside the shell
Heat radiation inner shell, heat radiation inner shell includes exhausting plate and deep bead, exhausting plate is communicated with the air outlet in the external world, deep bead and air-out
Plate connects formation heat-dissipating space, and wiring board is laid in heat-dissipating space.
Including aforementioned Chinese patent CN2593692Y and Chinese patent CN202546851U, dissipating of traditional electrical part
Hot mode is: be arranged on by fan inside machine, is sucked from air intake vent by cold wind, directly to electronic component quenching, then warp
Crossing air channel to be discharged outside housing by air outlet by hot blast, this radiating mode radiating effect is permissible, but still wants power consumption, does not has the feelings of electricity
Can not dispel the heat under condition.
Utility model content
For the above-mentioned deficiency of prior art, according to embodiment of the present utility model, it is desirable to provide a kind of low cost, structure
The compactest, the radiator structure of electrical heating utensil without fan not power consumption.
According to embodiment, the radiator structure of a kind of electrical heating utensil that this utility model provides, described electrical heating utensil bag
Including housing and the circuit board being arranged in housing, described circuit board has IGBT components and parts, its innovative point is, further
Including heat pipe, the heat absorbing end of heat pipe is connected with aforementioned IGBT components and parts, and the other end is connected with housing.
According to an embodiment, in the radiator structure of this utility model aforementioned electrical heating utensil, heat pipe riveting, welding or
Being connected by screw on IGBT components and parts, the contact surface of heat pipe and IGBT components and parts is rough and uneven in surface, and there is air centre, needs
Fill with the material of good heat conductivity, one layer of thin heat-conducting silicone grease between contact surface, can be smeared.
According to an embodiment, in the radiator structure of this utility model aforementioned electrical heating utensil, shell material is metal, example
Such as aluminum, die casting aluminium, ferrum and copper, housing is provided with radiating ribs.Common used material heat conductivity is: the heat conductivity of aluminum is about 180, presses
The heat conductivity of cast aluminium is about 120, the heat conductivity of ferrum is about 40, the heat conductivity of copper is about 390.Comparatively speaking, aluminum has
There is preferable heat conductivity, and electromagnetism can be shielded, prevent electromagnetic interference, be the most preferably material of housing.
According to an embodiment, in the radiator structure of this utility model aforementioned electrical heating utensil, the material of heat pipe be aluminum,
Aluminium alloy, copper or copper alloy.
According to an embodiment, in the radiator structure of this utility model aforementioned electrical heating utensil, the thickness of heat pipe is 3-
20mm, width is 5-50mm, and length determines according to the link position with housing.
Relative to prior art, in order to ensure heater IGBT normal work under the conditions of the environmental specification specified of circuit board
Making and reach the reliability objectives of product, thus meet the restrictive requirement to temperature rise, the heat absorbing end of heat pipe is connected with IGBT,
The other end is connected with housing, and the housing of electrical heating utensil is equivalent to a radiator, directly contacts with extraneous air, surface of shell
Temperature should be suitable with ambient temperature, and IGBT typically can reach 70-80 degree Celsius, there is a constant temperature between IGBT and housing
Difference, the heat of IGBT is quickly transferred on housing by heat pipe, causes case temperature to raise, and owing to housing area is big, and is provided with
Radiating ribs, takes in air by the amount of heat on housing by the way of natural heat dissipation, such circulation temperature lowering so that IGBT's
Temperature is maintained at a relatively low state, reaches the purpose effectively dispelled the heat.Radiator structure of the present utility model can be used for electric cooker,
Cooking stove, electromagnetic oven or Electromagnetic Heating kettle.
Accompanying drawing explanation
Fig. 1 is the radiator structure sectional view of the Electromagnetic Heating kettle according to this utility model embodiment.
Wherein: 1-IGBT；2-heat pipe；3-housing.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, this utility model is expanded on further.These embodiments are interpreted as only using
In this utility model being described rather than limiting protection domain of the present utility model.Reading the content that this utility model is recorded
