Description
Technical field
The invention belongs to radiator, be specifically related to a kind of synthesizing jet-flow radiator that can realize active heat removal.
Background technology
Radiator be conduct, a kind of device of release heat.Different according to the object of heat radiation, the radiating mode of employing is not identical yet, and some employing fin carry out the cooling mode of nature, and some employing provided with fans carry out air-cooled mode.For different applications, for heat radiation require differently, and the structure of radiator is also very high for the requirement of application scenario.At present, the mode of the passive heat radiation of most employing of radiator is dispelled the heat, the most volume of passive heat radiation device is larger, and the volume of radiator is restricting the development of related products to a certain extent, if can provide a kind of radiator that the volume of heat abstractor is reduced, the product of association area will no longer be subjected to the restriction of radiator and wait until fast-developing.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of synthesizing jet-flow radiator is provided, it is reasonable in design, simple in structure, easy to use, can realize active heat removal, reliability is high, volume is little, and is lightweight, and durability is high, heat dissipation capacity is large, without any noise, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of synthesizing jet-flow radiator, comprise thermal source, it is characterized in that: described thermal source upside is provided with fin, and described fin upside is provided with a plurality of fins, is provided with a plurality of synthesizing jet-flow devices between described fin, described synthesizing jet-flow device comprises the housing with cavity, described housing upside is provided with spout, and described housing lower end is provided with vibrating diaphragm, and described vibrating diaphragm downside is provided with piezoelectric patches.
Described fin is that cross section is rectangle, hexagon, ellipse or circular.
Described synthesizing jet-flow device is cylindric.
The present invention compared with prior art has the following advantages:
(1) this synthesizing jet-flow fansink designs is very reasonable, simple in structure, and operating personnel only need can automatically complete active heat removal to piezoelectric patches this device of switching on, and operating personnel need not training and get final product complete operation, use very easy.
(2) this synthesizing jet-flow radiator can be realized active heat removal, and reliability is very high.
(3) this synthesizing jet-flow heat sink size is 1/3rd of common radiator, and is lightweight, is convenient to very much carrying, transportation and installs.
(4) this synthesizing jet-flow radiator durability is high, dispels the heat by combining jet device, and heat dissipation capacity improves greatly, and without any noise.
(5) this synthesizing jet-flow radiator is convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

The specific embodiment
A kind of synthesizing jet-flow radiator as depicted in figs. 1 and 2 comprises thermal source 1, and described thermal source 1 upside is provided with fin 2, and described fin 2 is rectangle, hexagon, ellipse or circular for cross section.Described fin 2 upsides are provided with a plurality of fins 3, are provided with a plurality of synthesizing jet-flow devices 4 between described fin 3, and described synthesizing jet-flow device 4 is cylindric.Described synthesizing jet-flow device 4 comprises the housing 4-1 with cavity 4-2, and described housing 4-1 upside is provided with spout 4-3, and described housing 4-1 lower end is provided with vibrating diaphragm 4-4, and described vibrating diaphragm 4-4 downside is provided with piezoelectric patches 4-5.
the course of work of synthesizing jet-flow radiator of the present invention is: at first this synthesizing jet-flow radiator is arranged on the operating position, when thermal source 1 produces heat, at first the heat that thermal source 1 produces passes on the fin 2 of thermal source upside, spread on fin 2 by the conduction of heat heat, arrive on fin fin 3, the vibrating diaphragm 4-4 of synthesizing jet-flow device 4 produces vibration under piezoelectric patches 4-5 effect, thereby drive the air vibration in cavity 4-2, in cavity 4-2, air vibration is propagated outside cavity by spout 4-3, because the hole of spout 4-3 is smaller, in cavity 4-2, air produces and is vibrated to spout 4-3 place, form air-spray to housing 4-1 exterior circumferential radial attitude, can produce an eddy current in jet, eddy current is along with the direction that spout 4-3 sprays flows, when eddy current leaves when more remote, near spout 4-3 air also can flow thereupon, the temperature that makes fin 3 that flows fin 3 ambient airs reduces, reach the effect of heat radiation.
The above; it is only preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every according to the technology of the present invention essence to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection domain of technical solution of the present invention.
