Description
Technical field
The present invention relates to the structures and manufacturing process of a kind of heat loss through radiation piece, are mainly used in various electronic instruments, electric appliance
The heat loss through radiation of element surface.
Background technique
Electronic instrument constantly minimizes at present, especially mobile digital product to the small form factor requirements of appearance more
To be urgent, and the display screen of electronic instrument becomes greatly, and function is stronger and stronger, this certainly will consume more power, consumes power
Increase mean that the heat of generation is increasing, this is because the power of input electronic element 100% can not be utilized, electricity
Subcomponent input power must some be converted into heat, with electronic component generate heat increase, electronic component
Temperature will increase, especially with the rapid development of network technology, mobile phone, computer arithmetic speed be getting faster, operation
Speed is accelerated, and the generation of heat is just inevitably enlarged, if the heat that mobile phone, electronic computer generate cannot be quickly discharged to air
In, it will result in that mobile phone, the temperature inside electronic computer are excessively high, reduce the speed of service of mobile phone, electronic computer, in order to
So that the performance of mobile phone, electronic computer is guaranteed, mobile phone, the heat inside electronic computer must just be made to be discharged to air rapidly
In, and the heat of concentration of local can only be conducted rapidly and be scattered by graphite radiating film used at present, it can not be rapid by heat
Be diffused into air, thus currently on the market there are no reliable performance, cost performance is suitable, is suitable for handheld electronics makes
Heat dissipation technology, the especially product of collection high thermal conductivity and heat loss through radiation occur.
Summary of the invention
In order to overcome the shortcomings of that existing graphite radiating film occurs in use, the present invention to solve the above-mentioned problems, is proposed
A kind of heat loss through radiation piece, a kind of heat loss through radiation piece are mainly made of metal layer and heat loss through radiation layer, metal layer and need to radiate
Matrix is in close contact, and since metal layer has very high heating conduction, the heat of matrix can be rapidly conducted to metal layer, gold
Metal layer whole surface can be distributed in rapidly for the heat that matrix conducts by belonging to layer, keep the heat of matrix high-temperature area rapid
It is diffused into the low-temperature region of metal layer, reaches the concentration degree for reducing rapidly matrix high-temperature area heat, metal layer is by the warm of itself
Amount is conducted to heat loss through radiation layer, and metal layer conductive conducts heat mainly along the direction of vertical metal layer to the heat of heat loss through radiation layer

It is in far-infrared radiation to air, according to law of conservation of energy it is recognised that radiation dissipates by the converting heat of own absorption
Thermosphere it is radiation infrared must consumption of calorie will constantly disappear as heat loss through radiation layer is continuously radiation infrared
The heat for consuming heat loss through radiation layer, can thus accelerate conduction of the metal layer heat to heat loss through radiation layer, due to matrix heat meeting
It is rapidly conducted to metal layer, the heat of matrix will be constantly consumed, to achieve the purpose that reduce substrate temperature.
The technical solution adopted by the present invention to solve the technical problems is: a kind of heat loss through radiation piece is mainly by adhesive layer, gold
Belong to layer, heat loss through radiation layer, surface layer composition, adhesive layer is brushed in metal layer bottom, and adhesive layer is tightly engaged into matrix, metal layer
It is tightly engaged into heat loss through radiation layer, heat loss through radiation layer surface spraying surface；Matrix is heat source, and the heat of matrix is fast by adhesive layer
Speed is conducted to metal layer, and metal layer has good heating conduction, and the heat that matrix conducts can be distributed in rapidly by metal layer
Metal layer whole surface allows the heat of matrix high-temperature area to rapidly diffuse into the low-temperature region of metal layer, reaches rapid drop
The concentration degree of low matrix high-temperature area heat, heat loss through radiation layer also have good heating conduction, heat loss through radiation in vertical direction
Layer is tightly engaged into metal layer, this just allows the heat of metal layer pass to heat loss through radiation layer along vertical metal layer direction,
Heat loss through radiation layer has heat-far infrared conversion function, the heat of itself can be converted to far-infrared radiation to air
In, heat loss through radiation layer will consume the heat of itself while radiation infrared, and heat loss through radiation layer can be radiated continuously far
Infrared ray, then also will continuous consumption self heat, this heat that just will form metal layer is continuously conducted to heat loss through radiation layer,
The heat of matrix is continuously conducted to metal layer, to achieve the purpose that reduce substrate temperature.
The good metal film production of the heating conductions such as copper foil, aluminium foil, silver foil can be used in metal layer.
Adhesive sticker or the production of other bonding agents, adhesive layer can be used in adhesive layer can be divided into two from heating conduction
Kind, thermally conductive adhesive layer, not thermally conductive adhesive layer, the thermally conductive adhesive layer of the thermally conductive bonding agent production of adhesive layer selection, adhesive layer selection is commonly
Bonding agent makes not thermally conductive adhesive layer.
Heat loss through radiation layer is mainly made of far infrared radiation powder, conductive powder, bonding agent, and far infrared radiation powder, which can choose, to be received
The pulvis with radiation infrared function such as rice zinc oxide, nano magnesia；Conductive powder can choose graphene, graphite powder,
The pulvis such as carbon black, aluminium nitride, bonding agent can choose acrylic compounds, epoxies, polyurethanes bonding agent；Spoke after curing
Penetrate a variety of materials mass ratio in heat dissipating layer are as follows:, far infrared radiation powder is 4-20%, conductive powder 35-45%, and bonding agent is
18-35% will be bonded dilution agent with suitable solvent first, be proportionally added into after waiting bonding agents to be completely dissolved in a solvent remote
Then infra-red radiation powder, conductive powder stir evenly stand-by-heat loss through radiation layer slurry.
The thickness control of heat loss through radiation layer is between 0.3-1mm.A kind of heat loss through radiation piece heat dissipation effect and heat loss through radiation layer
Thickness direct proportionality.
Metal layer thickness controls between 0.06-0.2mm, the thickness of heat loss through radiation piece heating conduction and metal foil a kind of at
Proportional relationship, a kind of more thick heat loss through radiation piece heating conduction of metal foil are better.
Surface thickness gets over Bao Yuehao, the blocked up transmission that will affect far infrared of surface thickness, and surface thickness is controlled in 25-45
Between micron.
