Abstract
The heat radiator for refrigerator display includes display casing, heat isolating structure and heat conducting structure. The display casing located inside the slot of the refrigerator protects the inside display with circuit board against outer impact and has opening corresponding the circuit board. The heat isolating structure is filled in the space between the display casing and the slot to avoid the low temperature of the refrigerator on the other parts and has heat dissipating groove in the part connecting to the opening. The heat conducting structure located inside the heat dissipating groove absorbs heat from the surface of the display with the circuit board and transfers the heat to the heat isolating structure. The heat radiator cools the display effectively with the low temperature inside the refrigerator without producing noise.

As shown in Figure 1, be provided with display 2 in the front of refrigerator 1.Display 2 operated by rotary motion touch-screens are controlled.
As shown in Figure 2, be arranged on the circuit board 12 of display 2 inside and be provided with thermal discharge little element 13 and the big element 14 of thermal discharge respectively, for example the element that thermal discharge is big has central processing unit (CPU).On the big element 14 of thermal discharge, be provided with the heat sink 16 that absorbs each element liberated heat, and, on heat sink 16, be provided with cooling fan 18 for cooling heat dissipation plate 16.
When using this heat abstractor, because the rotation of cooling fan produces very big noise.Particularly, with the refrigerator setting in the family the parlor or the kitchen in the time, big like this noise is easy to cause that the consumer's is discontented.After the useful life of the cooling fan that is provided with for the element of cooled interior, need change.Certainly, the operation of this replacing can not undertaken by user oneself, but is undertaken by the professional attendant of service centre, and is therefore cumbersome.And, in case finding cooling fan, the user do not work, then Nei Bu element all can damage because of being heated.
Summary of the invention
Technical problem to be solved by this invention is, a kind of heat abstractor is provided, and when the element of cooling display interior, can not make a noise, and can not have any impact to the work of display and heat abstractor service life, can forever use.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of refrigerator heat abstractor of display, comprise: display casing, heat insulation structural and conductive structure, described display casing is positioned at the inside of the insertion groove of refrigerator, when being subjected to extraneous impact, the inner display that the element circuit board of heat release is housed of protection, and in the partial design that contacts with the element circuit board opening; Described heat insulation structural is filled the space between described display casing and the refrigerator insertion groove, prevents that other parts are subjected to the influence of refrigerator low temperature, and is provided with radiating groove on the part of joining with opening; Described conductive structure is positioned at radiating groove, absorb heat from the display surface of circuit board that described element is installed after, be delivered on the heat insulation structural.
Contain aluminium element in the described conductive structure.
Described conductive structure is a heat sink.
Between conductive structure and display, append and be provided with the high metallic plate of thermal conductivity factor.
At least contain any in aluminium and the copper in the described metallic plate.
Between the inwall of the radiating groove of described heat insulation structural and conductive structure, append and be provided with heat sink.
The invention has the beneficial effects as follows: during cooling display interior element, heat abstractor does not make a noise, and has not the permanent life-span that can have any impact to display and heat abstractor.Heat insulation structural has also possessed the function of cooling display, can make the structure of heat abstractor simpler.Effectively utilized the low temperature of refrigerator inside, the power supply supply that need not other just can be finished the cooling task.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: the present invention is not confined to the embodiment of following explanation.
As shown in Figure 3, on refrigerator 1, formed the insertion groove 20 of the heat abstractor that display and the present invention's design are set.
Be subjected to extraneous impact and damage for fear of display 30, utilize display casing 40 that it has been protected.Usually, display 30 is with identical in the past, possessed the circuit board (not expression among the figure) that is provided with the big element of the little element of caloric value and caloric value, more obvious for the circuit board (back explanation) that has the big element of caloric value being carried out exothermal effect, therefore on display casing 40, be provided with opening 42, be exposed to the outside so that be provided with the outer surface of the circuit board of the big element of caloric value.
In order to absorb heat from outer surface, the outer surface of the circuit board of the element that the conductive structure 50 that makes good heat conductivity by opening 42 and caloric value are big contacts.Conductive structure 50 contains aluminium component, adopts solid type structure or other various structures.And conductive structure 50 also can be to possess the general base and the fin of fin.
Low temperature for fear of refrigerator 1 inside causes harmful effect to display 30, is provided with to have certain thickness heat insulation structural 60.On heat insulation structural 60, formed the display casing insertion groove 62 that can insert display casing 40, and be provided with the radiating groove 64 that can insert conductive structure 50 in the inside of display casing insertion groove 62.Be provided with radiating groove 64 part thickness less than around the thickness at other positions.
As mentioned above, owing to reducing of radiating groove 64 bottoms 66 and refrigerator 1 inner spacing, the high heat that transmits by conductive structure 50 can be fallen by the sub-cooled of refrigerator 1 inside.That is, heat insulation structural 60 utilizes the low-temperature heat quantity of radiating groove 64 and refrigerator 1 inside to cool off the heat that display 30 is sent when having the transmission of the refrigerator of prevention 1 inner cryogenic heat.
As shown in Figure 4, formed the opening 42 of display casing 40 on circuit board 34 outer surfaces 32 of the element that the installation caloric value in display 30 circuit boards is high, and contacted with conductive structure 50 by opening 42.And, between display casing 40 and conductive structure 50 and refrigerator insertion groove 20, formed heat insulation structural 60.Conductive structure 50 absorbs the heat (chain line arrow) of the circuit board 34 of display 30, it is passed to the radiating groove bottom 66 of heat insulation structural 60, and these heats can be cooled off rapidly by the low temperature of refrigerator 1 inside (solid arrow).
In an alternative embodiment of the invention, between the outer surface 32 of the circuit board of the big element of display caloric value and conductive structure 50, append and be provided with the quite high metallic plate of thermal conductivity factor (not expression among the figure), can absorb the heat of display 30 circuit boards 34 thus rapidly.Contain aluminium and copper in this metallic plate.
In an alternative embodiment of the invention, on the bottom 66 of conductive structure 50 and heat insulation structural 60, append and be provided with the heat sink (not expression among the figure) that possesses base and fin, behind the heat that absorbs conductive structure 50, can promptly be cooled off thus by the low-temperature heat quantity of refrigerator 1.
