Description of the Invention: . . . [Technical Field] The present invention relates to a heat dissipation technology, and more particularly to a passive heat sink and a street lamp heat sink. _ [Prior Art] Due to the large number of applications of electrical energy, various types of electrical equipment have different heat dissipation problems. For example, 'a common high-power LED (Light Emitting Diodes hereinafter referred to as LED) street light. The junction temperature of the LED is generally not φ. It is allowed to exceed the limit of 85 °C. When the LED junction temperature exceeds 85 °C, the lifetime of the LED will be reduced by 50% for every 5 °C, and the brightness of the LED street lamp will also be reduced. More than 50% of the mother's half-year speed decay. Therefore, how to transfer the heat generated by the LED junction to the ambient heat of the street lamp becomes a key issue for prolonging the life of the LED 'lights and delaying the brightness decay. _ The LED street lamp heat dissipation structure used in the prior art is generally a die-cast or extruded aluminum alloy heat sink, as shown in FIG. 1 , the LED bulb 1 is mounted on the lamp holder 2, and the aluminum alloy heat dissipation base plate 3 is die-cast connected to the LED bulb 1 On the lamp holder 2, the heat dissipation base plate 3 is vertically connected with the heat dissipation fins 4, and the heat dissipation fins 4 are generally disposed to extend outward. In the process of achieving heat dissipation, the heat generated by the LED bulb 1 is transferred to the air through the lamp holder 2, the heat dissipation substrate 3, and the heat dissipation fins 4 by means of metal heat conduction. However, the aluminum alloy heat dissipation structure has the disadvantage that the thermal conductivity of the aluminum alloy is watts per metre Kelvin (W/MK). When the heat is transferred on the smelting alloy, the temperature decreases greatly with the increase of the transmission distance. Even if the device has a large surface area, the actual heat dissipation area of the heat dissipation is small due to the large thermal resistance of the internal heat conduction, and the heat dissipation effect is not good. Another LED street lamp heat dissipation structure of the prior art uses a loop heat pipe (LHp) heat sink. LHp is a typical linear heat transfer element. The heat dissipation principle is shown in Figure 2. The heat dissipation medium is filled into the heat dissipation back to the 4 1379065 road tube 100 t, and the evaporation end 110 is in contact with the heating region of the electronic component to absorb heat from the liquid medium. Evaporating to a gaseous state, and then the heat dissipating medium flows from the evaporation end 110 of the divergent loop tube 100 to the condensing end under the action of the wick 120, during which heat is transferred to a larger heat dissipating surface, and the heat dissipating medium is again The gaseous state changes to a liquid state, and returns to the evaporation end 110. The LHp is used to dissipate the crying. When the street lamp heat dissipation structure is used, a heat dissipation back pipe '' is disposed on the outer side of the lamp cover, and is disposed at the heat source, usually at the top of the lampshade. The evaporation end of the heat dissipation loop tube. However, this LHP county method also exists - fixed _, heat recovery and divergence area = touch = small, contact thermal resistance is large, can not obtain a large effective expansion of heat dissipation area, heat dissipation is not good.
