Specific embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not
It is limited to this.
Embodiment 1
As shown in Figure 1 and Figure 2, double heat abstractors of a kind of LED street lamp, including multiple LED integrated chips 1, substrate 2, heat are handed over
Element 3, fin inserting type heat radiator 4 and synthesizing jet-flow radiator 5 are changed, the LED integrated chips 1 are fixed on a substrate 2, the substrate 2
It is fixed on heat exchange elements 3, the end face center position of the heat exchange elements 3 sets fin inserting type heat radiator 4, the inserted sheet radiating
The synthesizing jet-flow radiator 5 for each side setting equal number of device 4, the synthesizing jet-flow radiator is arranged on heat exchange unit
The top surface of part.
The fin inserting type heat radiator 4 is made up of multiple radiating fins, multiple radiating fins can with it is arranged in parallel or in radian arrange
Row are arranged in sun fancy.
As shown in figure 4, the cavity 501 of the synthesizing jet-flow radiator 5 an including rectangular cross-section, the cavity it is upper,
Left and right inwall is provided with liquid-sucking core 503, and the cavity top is provided with the passage 505 of built-in piston 504, and the cavity bottom is provided with
Elastic film 502, the elastic film has certain distance apart from heat exchange elements upper wall, and its distance is according to actual synthesizing jet-flow
How much decisions of the size of radiator, the elasticity of elastic film and liquid refrigerant, the present embodiment distance 0.5mm-5mm with
Interior, the elastic film is provided with liquid refrigerant 506.
Fin inserting type heat radiator 4 is pointed in access portal direction on the synthesizing jet-flow radiator, and fin inserting type heat radiator radiates and penetrates
Flow heat dissipation is combined, and substantially increases radiating efficiency.
The synthesizing jet-flow radiator 5 of the present embodiment has 4, one group two-by-two, is separately positioned on the left and right two of fin inserting type heat radiator
Side, and it is symmetrically placed, circulative convection can be formed, radiating effect is more preferable.
The course of work of the invention：
The heat that LED integrated chips 1 are produced when lighting passes to heat exchange elements 3, the energy of heat exchange elements 3 by substrate 2
At enough elastic films 502 heat passed to rapidly in fin inserting type heat radiator and synthesizing jet-flow radiator 5, one side blade inserting dissipates
Hot device reaches the purpose of passive radiating with air contact, and on the other hand, the liquid refrigerant 506 at elastic film 502 is due to receiving
Heat and expand rapidly, increase in chamber gas pressure intensity, promote piston 504 to move upwards, air is sprayed at passage 505, by
Reduce in the quality of liquid refrigerant, elastic film 502 can produce isolating in physical distance with the upper wall of heat exchange elements 3,
The liquid refrigerant 506 for reaching condensation end can be because the reduction of temperature forms liquid, as liquid-sucking core 503 is back to interior Thin Elastic
At film, now pressure reduces in synthesizing jet-flow radiator 5, and piston 504 is moved downward, and air is sucked at passage 505, with liquid
