Description
Technical field
The invention belongs to thermoelectric conversion fields, and in particular to a kind of Miniature temperature control structural unit.
Background technique
Mobile phone heating problem during continuing a journey the long period is serious.With development in science and technology, each device integration is increasingly
Height, it is extremely harsh for interior of mobile phone space utilization and design requirement, even if having accomplished optimal case, it is also difficult to which that seeks going has
The sinking path of effect.By taking apple digital product as an example, heat sink conception mainly passes through aluminium alloy full metal jacket, even if can do
To the ingenious thermal characteristic that metal is utilized, the frequency reducing protection machine for triggering equipment can be still had an impact to core original part
System.
Summary of the invention
The purpose of the present invention is to overcome the defects in the prior art, provides a kind of Miniature temperature control structural unit.
The present invention to achieve the above object, using following technical scheme:
Miniature temperature control structural unit, including contacted with heater element heat exchange substrate, be arranged on the heat exchange substrate
Metal foam stratum reticulare, the phase-change wax that is filled in inside the metal foam stratum reticulare and coated in the metal foam net
The graphene of hole surface.
The metal foam is made of copper, aluminium or nickel.
The range of the hole density of the metal foam is 60PPI~130PPI, and the range of porosity is 0.8~0.9, thick
Degree is 10nm~1mm.
Compared with prior art, the beneficial effects of the present invention are:
The application conducts heat using metal foam, and the phase transformation pair of the phase-change wax by being arranged in metal foam net
Heat is absorbed, and by Seebeck effect, the heat of heater element is converted, and the addition of graphene keeps its acquisition superpower
Conductive characteristic.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, below with reference to embodiment pair
The present invention is described in further detail.
Embodiment 1: Miniature temperature control structural unit, including contacted with heater element heat exchange substrate, described change is set

100PPI, the range of porosity is 0.8~0.9, with a thickness of 0.5mm.
Embodiment 2: Miniature temperature control structural unit, including contacted with heater element heat exchange substrate, described change is set
Metal foam stratum reticulare on hot substrate, the phase-change wax being filled in inside the metal foam stratum reticulare and coated in the gold
Belong to the graphene of foam mesh surface.The metal foam is made of aluminium.The range of the hole density of the metal foam is
60PPI, the range of porosity is 0.8~0.9, with a thickness of 10nm.
Embodiment 3: Miniature temperature control structural unit, including contacted with heater element heat exchange substrate, described change is set
Metal foam stratum reticulare on hot substrate, the phase-change wax being filled in inside the metal foam stratum reticulare and coated in the gold
Belong to the graphene of foam mesh surface.The metal foam is made of nickel.The range of the hole density of the metal foam is
130PPI, the range of porosity is 0.8~0.9, with a thickness of 1mm.
So that the structure is directly completed heat to electricity conversion by Seebeck effect, gained electric energy will and can be converted and directly export work
For elements such as operative sensor, LED (LightEmittingDiode light emitting diode).For example, passing through setting power supply LED
The electric energy being converted directly is supplied to screen backlight LED by threshold voltage parameter.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
