Abstract
The utility model relates to the technical field of high-power LED street lamp heat dissipation, in particular to a high-power LED street lamp heat dissipation system, which comprises a lamp housing and an LED module support mounted inside the lamp housing. A plurality of heat conductive tube grooves are arranged on the LED module support, heat conductive tubes are inserted into the heat conductive tube grooves, and the other ends of the heat conductive tubes are fixedly connected with the inner side of the lamp housing. After the system adopts the structure, on one hand, heating of an LED module can be dissipated via the LED module support and heat dissipating fins of the LED module, on the other hand, heating of the LED module can also be transmitted to the LED lamp housing directly by using conduction of the heat conductive tubes or indirectly through the LED module support, a heat dissipation area is further enlarged by the aid of the lamp housing and the heat dissipating fins of the LED module, and accordingly heat dissipation effect is enhanced.
Description
Technical field:
The utility model relates to high-power LED street lamp heat dissipation technology field, refers in particular to a kind of high-power LED street lamp cooling system.
Background technology:
The operating temperature of LED is very big to its influence in service life, and therefore for great power LED, the quality of radiating effect directly influences its service life.Existing great power LED module normally is installed on the LED module support, so its heat radiation also mainly realizes by LED module support and LED street lamp shell.The pattern of LED module support is varied, and for strengthening its radiating effect, general way is radiating fin as much as possible to be set to increase its area of dissipation as far as possible on LED module support.This mode can satisfy the radiating requirements of great power LED module to a certain extent, but because the effective heat conduction of shortage contacts between LED module support and the LED street lamp shell, only rely on air with and a small amount of contact site of installation place come heat conduction, obviously heat-conducting effect is not good, has therefore limited the heat radiation of whole LED street lamp yet.
The utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of prior art, and a kind of high-power LED street lamp cooling system of better heat-radiation effect is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of high-power LED street lamp cooling system, comprise lamp housing and be installed in the interior LED module support of lamp housing, wherein: on described LED module support, offer some heat conduction tube seats, described heat conduction tube seat interpolation is established heat pipe, and the other end of described heat pipe and described lamp housing inboard are connected and fixed.
Be provided with several arc grooves in the inside of described lamp housing, described arc groove is fixed in by a heat pipe pressing plate in the end of described heat pipe.
Described heat conduction tube seat comprises " D " shape heat conduction tube seat offered along the LED module stationary plane of described LED module support and the circular heat conduction tube seat that runs through described LED module internal stent.
The mounting seat bottom of described LED module support is provided with radiating fin.
The described lamp housing outside is provided with radiating fin.
After the utility model adopts said structure, on the one hand, the heating of LED module can be dispelled the heat by LED module support and radiating fin thereof, on the other hand, the heating of LED module also can utilize the conduction of heat pipe directly or by LED module support to conduct the lamp housing to LED indirectly, further strengthens radiating effect thereby further increase area of dissipation by lamp housing and radiating fin thereof.
Description of drawings:
Fig. 1 is the structural representation of LED module support in the utility model;
Fig. 2 is the structural representation of the utility model cooling system;
Fig. 3 is the external structure schematic diagram of the utility model lamp housing.
The specific embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
At first as shown in Figure 2, high-power LED street lamp cooling system described in the utility model comprises lamp housing 1 and is installed in LED module support 2 in the lamp housing 1, wherein: on described LED module support 2, offer some heat conduction tube seats 21, plug heat pipe 3 in the described heat conduction tube seat 21, and the other end of described heat pipe 3 and described lamp housing 1 inboard are connected and fixed.
Particularly, be provided with several arc grooves 11 in the inside of described lamp housing 1, described arc groove 11 is fixed in by a heat pipe pressing plate 4 in the end of described heat pipe 3.By the pressing and fixing of arc groove 11 with arc heat pipe pressing plate 4, heat pipe 3 is fully contacted with the inside of lamp housing 1, increase effective heat-conducting area, accelerate heat radiation.
Again in conjunction with Fig. 1, shown in Figure 3, described heat conduction tube seat 21 comprises " D " shape heat conduction tube seat 211 offered along the LED module stationary plane 20 of described LED module support 2 and the circular heat conduction tube seat 212 that runs through described LED module support 2 inside.Wherein " D " shape heat conduction tube seat 211 has 6,3 of each LED module stationary plane 20 correspondences, " D " shape heat conduction tube seat 211 corresponding " D " shape heat pipes of installing, the plane place of " D " shape heat pipe is directly contacted with LED module 4, the heating of LED module 4 is directly conducted to LED lamp housing 1 by this heat pipe dispel the heat; The circular arc portion of " D " shape heat pipe contacts with LED module support 2 and conducts its heat and dispels the heat for LED lamp housing 1 simultaneously; And the circular heat conduction tube seat 212 that runs through described LED module support 2 inside has 2, and it is corresponding installs circular heat pipe, the heat of LED module support 2 is conducted to LED lamp housing 1 dispel the heat.
In addition, mounting seat 22 bottoms of described LED module support 2 are provided with radiating fin 221.Described lamp housing 1 outside is provided with radiating fin 12.Its effect is further to increase area of dissipation, strengthens radiating effect.
In the utility model, housing 1, LED module support 2, heat pipe pressing plate 4 etc. all adopt the good aluminium manufacturing of heat conduction.
Obviously; the above is a specific embodiment of the present utility model; the length of LED module support can be set as required so that a plurality of LED modules to be installed; the number of its size, heat conduction tube seat also can be set as required; base also can be widened so that more radiating fins etc. to be set; its structural principle is consistent with the utility model, therefore also should be at the row of protection domain of the present utility model.
In sum, the utility model guarantees that when keeping good looking appearance area of dissipation is enough big, radiating efficiency is high, satisfies great power LED module heat radiation requirement, and effectively alleviates product weight.
