The specific embodiment
With reference to the accompanying drawings, the heat radiation of internet electric refrigerator master controller of the present invention with said structure and the embodiment of electromagnetic interference masking structure are elaborated.
Fig. 3 is that the part of the internet electric refrigerator with master controller of the embodiment of the invention is cut oblique view.
Fig. 4 is the heat radiation and the electromagnetic shielding section of structure of the internet electric refrigerator master controller of the embodiment of the invention.
As shown in the figure, be formed with the device space 31 at refrigerating chamber that is used for stored food and refrigerating chamber top, the said equipment space 31 is provided with the various parts relevant with the function of refrigerator.The bottom surface in the said equipment space 31 is formed with under(-)chassis (base frame) 33, and above-mentioned under(-)chassis 33 is used to divide the storage space and the device space 31.The top device space 31 inside of above-mentioned under(-)chassis 33 are provided with the electronic installation and the various parts of control refrigerator all functions.Though do not demonstrate in the accompanying drawing, the top of above-mentioned under(-)chassis 33 also is provided with the supply unit that obtains the power supply supply from the outside, the parts of control refrigerator function and the parts relevant with the internet etc.
The said equipment space 31 is provided with master controller 35, and above-mentioned master controller 35 is used to control the work of refrigerator, and frame shell (frame cover) 37 constitutes the outward appearance of above-mentioned master controller 35.Said frame shell 37 is long and the highly long hexahedral shape of wide ratio, is formed with porous portion 39 above the said frame shell 37, and above-mentioned porous portion 39 is used for will controlling internally the heat of the various parts generations of refrigerator and disperses.A plurality of through holes are bored a hole into according to a determining deviation by above-mentioned porous portion 39.
The inside of said frame shell 37 is formed with the inner space 41 that distinguishes with the device space 31.Be provided with printed circuit board (PCB) 43 above the under(-)chassis 33 of above-mentioned inner space 41.Above-mentioned printed circuit board (PCB) 43 tops are provided with the central processing unit 45 of the various parts that are used to control the said equipment space 31, and above-mentioned central processing unit 45 is electrically connected on the circuit on the above-mentioned printed circuit board (PCB) 43.
In addition, different with prior art, except above-mentioned porous portion 39, all said frame shells 37 all cover above-mentioned inner space 41, are used to interdict the electromagnetic wave that the various electronic units such as central processing unit 45 in the above-mentioned inner space 41 produce.
For the heat that above-mentioned central processing unit 45 is produced is directly delivered to said frame shell 37, the upper end central authorities of above-mentioned central processing unit 45 are provided with the finger-like lath (fingerstrip) 47 of bossed finger shape.In the present embodiment,, be not limited only to this,, can adopt Any shape as long as the heat that above-mentioned central processing unit 45 produces can be able to be delivered to said frame shell 37 though above-mentioned finger-like lath 47 has adopted the shape for lugs of finger-shaped.
Above-mentioned finger-like lath 47 has adopted elastic materials such as spring, and the strength strain that can apply along with the outside closely is combined between above-mentioned central processing unit 45 and the said frame shell 37, does not have the danger of disengaging.
Above-mentioned finger-like lath 47 is in order to disperse the heat that above-mentioned central processing unit 45 produces from the upper end of central processing unit 45, the metal material good by heat-conductive characteristic forms.
On the one hand, the metal material that pyroconductivity is low brings out electromagnetic generation usually probably.So in order to minimize electromagnetic generation, above-mentioned finger-like lath 47 is preferably by electric conductivity and the good metal material making of heat-conductive characteristic such as copper.
Below the heat radiation of internet electric refrigerator central processing unit of the present invention with said structure and the effect of electromagnetic interference masking structure are elaborated.
At first, connect the power supply of refrigerator, above-mentioned central processing unit 45 drives, and through after the certain hour, above-mentioned central processing unit 45 produces certain heat.The major part of above-mentioned heat is delivered to the finger-like lath 47 on the top that is formed on above-mentioned central processing unit 45.Above-mentioned finger-like lath 47 is made by the good metal material of heat transfer performance, is delivered to top very soon so the heat of above-mentioned generation forms the inclined plane along the surface of finger-like lath 47.
Above-mentioned heat is dispersed from above-mentioned master controller 35 inside and is not detained, and shown in the arrow of Fig. 4 solid line,, perhaps is delivered on the said frame shell 37 by above-mentioned finger-like lath 47 and dispels the heat to the outside radiation by the porous portion 39 on the said frame shell 37.At this moment said frame shell 37 plays the effect of the heat sink that the heat of inside is dispersed to the outside, and above-mentioned finger-like lath 47 plays the function on the said frame shell 37 of effect that the heat that above-mentioned central processing unit 45 is produced has been delivered to heat sink.So above-mentioned master controller 35 temperature inside will not rise.
In addition, the electromagnetic wave that above-mentioned central processing unit 45 produces, shown in the arrow of Fig. 4 dotted line, will be by the front of said frame shell 37 and the back side and left and right side blocking, leak to the above-mentioned device space 31 so prevented electromagnetic wave, can be for being arranged on the device space 31 and the electronic unit of the periphery of said frame shell 37 brings out Electromagnetic Interference.
In sum, basic fundamental thought of the present invention is in order to interdict the electromagnetic wave that above-mentioned central processing unit 45 produces, designed the frame shell 37 that can cover master controller 35 fully, need not to use extra cooling device such as cooling fan also can disperse the heat that central processing unit 45 produces, suppressed the temperature rising.
Up to the present, though be that the center has been described in detail to embodiments of the invention, the personnel that have general knowledge in the technical field of the invention can propose a lot of distortion in basic fundamental thought range of the present invention.Basic fundamental thought of the present invention is embodied in the patent request scope, and all differences point in the equal with it scope all should be interpreted as belonging to scope of the present invention.
