Description
Technical field
The present invention relates to radiator, be specifically related to the especially radiator of great power LED of electronic product.
Background technology
Large power, electrically sub-elements such as great power LED are because caloric value is big, generally all need to be provided with radiator, otherwise can influence the life-span owing to caloric value is big, reduce function and influence operating efficiency, when the radiator of traditional structure uses and electronic component be fixed as one, the heat transferred that mode by the heat transmission is sent element is to radiator, mode with thermal radiation and convection current distributes heat again, this type of radiator generally is provided with radiating fin or the fin that increases its surface area, its materials and processing and fabricating cost can increase, though radiator and electronic component are fixed as one and have increased area of dissipation in addition, heat is produced to be piled up, the heat that is unfavorable for element surface in time scatters and disappears, can have influence on radiating effect, in certain space, not that area of dissipation is the bigger the better, though area of dissipation has increased, but it is long-pending also to have formed thermal capacitance simultaneously, hot stack is arrived together, thereby reduced radiating effect, its radiating efficiency can't be improved, hot-air just gathers around radiator, owing to can not produce directed movement, its water conservancy diversion effect is inevitable bad, the heat that absorbs on the radiator is not easy to scatter and disappear away, therefore often need on this type of radiator that fan is installed and carry out water conservancy diversion, accelerate radiating rate, improve radiating efficiency, otherwise its radiating efficiency can't obtain significantly breaking through fast, can increase input and power consumption but fan is installed, use cost can increase to some extent.
Summary of the invention
Have guide functions when the purpose of this invention is to provide a kind of heat radiation, can not produce heat build-up, good heat dissipation effect, the directional stream-guidance-type radiator that cost and use cost are low.
Technical solution of the present invention is: it comprises radiator device body, and the radiator device is as the equidirectional alveolate texture that is densely covered with the hot tropism's passage of regular hexagon that connects radiator device body.
Technique effect of the present invention is: have guide functions during its heat radiation, can not produce heat build-up, good heat dissipation effect, cost and use cost are low, leave the water conservancy diversion and the supplements cold space of certain distance during use between radiator and the element, to form air nature flow-guiding channel, directional stream-guidance by air act as element radiating, this radiator is to use Climatology, aerodynamics, materialogy, the new-type radiator that the method for mathematical modeling is designed, it has broken through the traditional heat-dissipating device only increases the constraint of radiating effect by increasing area of dissipation, has broad application prospects.

Embodiment
Embodiment 2, as shown in Figure 2, with the difference of embodiment 1 be that each hot tropism's passage 11 is positive triangle hole.
Embodiment 3, as shown in Figure 3, with the difference of embodiment 1 be that each hot tropism's passage 11 is circular port.
Embodiment 4, as shown in Figure 4, with the difference of embodiment 1 be that each hot tropism's passage 11 is the square hole.
The optimum structure of hot tropism's passage 11 of this radiator is bionic regular hexagon hole, and radiator is an alveolate texture, and this structure is in the situation following table area maximum with volume, and material usage is economized most, and cost is minimum.These hot tropism's passages 11 can play guide functions, make air produce directed movement, thus calm not by the external force situation under, air movement is taken away heat, rather than uses the air transmitted heat.
This radiator utilizes air as medium, the heater element heated air, and hot-air rises, and cold air comes in to replenish, and transmits heat.And traditional heat-dissipating device (not adding fan) is not noticed and is utilized air to use as a kind of " coolant ", but do heat conduction with him, and the coefficient of heat conduction of air is lower, radiator generally is to be made by the good conductor metal of heat, the heat that element produces can be to the traditional heat-dissipating device conduction of lower temperature, finish heat loss through conduction, go out by heat sink radiates again.During the environment heat radiation towards periphery of the radiator of higher temperature, under indoor calm situation, be exactly that because the coefficient of heat conduction of air is lower, its radiating efficiency is very low by the peritropous air heat radiation of heat conduction.
The radiating surface of element will make progress during use, this radiator above the element and and element between leave the water conservancy diversion and the supplements cold space of certain distance, to form air nature flow-guiding channel, the heat conduction air is taken away heat through element surface through the route of the tower structure curve of cold water all around from the bottom from bottom to top, upwards hot-air is upwards derived again through overheated tropism's passage 11, form the nature water conservancy diversion, its lasting heat conduction capable of circulation, heat-conducting effect is better, and radiator itself also has the heat radiator effect.
Because applied thermodynamics when this radiator uses, the principle that heated air rises, the best mode of this radiator when work is that hot tropism's passage 11 is parallel with gravity direction, and the working method of hot tropism's passage 11 allows air movement that the qualitative and heated air of direction is arranged exactly.Under calm condition, hot-air is subjected to gravitational effect, and the back that is heated is basic vertically rises, hot tropism's passage, and for air provides kinetic energy and direction, hot-air rises straight up.
This radiator is distinguished with the maximum of traditional heat-dissipating device, the traditional heat-dissipating device mainly dispels the heat by heat conduction and thermal radiation, and the present invention is dispelled the heat by the flowability of air, is equivalent to install diversion fan, rely on air flows to take away heat, so its radiating effect is better.Because it has certain distance with element itself in use, can not produce hot stack, and heat is in time derived, and makes element radiating better, it also can use radiating effect better with fan combination.
In the traditional heat-dissipating device, after fin work, its ambient air is heated also and can rises, but owing to there is not inlet of cold air, cold air can not get replenishing, the flow velocity of its rising is very slow, and such radiator can only lean on the thermal conductivity of air to carry out heat conduction, so influenced the radiating effect of this structure radiator.The break traditions drawback of radiator of radiator of the present invention makes cold and hot air separately, allows air Heated Flow voluntarily, allow air take away the heat of element and radiator, this air leaves heat abstractor then, and cold air replenishes, so constantly circulate, reach the purpose of heat radiation.
In sum, this radiator has following characteristics:
1, the present invention utilizes aerodynamics, the principle of hot air rising, the heat heating that allows element send Air rises after making air heat, and cold air replenishes around it, by Air Flow heat Amount is taken away;
2, it utilizes a lot of hot tropism's passages, finishes the air conduction process;
3, it utilizes heat to produce air movement, and produces convection current;
4, its heat-conducting medium air of using utilizes the flowability of air, does not mainly utilize the thermal conductivity of air;
5, its material is the good conductor of heat, the material that conductive coefficient is higher;
6, adopt bionic positive six to connect the shape pore structure, can improve the area of dissipation under equal volume;
7, on the heat radiation working face of radiator, air carries out heat conduction through the cooling tower structure curve, and it is faster that cold air replenishes speed, and radiating effect is better.
