Abstract
The utility model discloses a structure of a radiator with built-in fins. The structure of the radiator with the built-in fins comprises a hollow heat dissipation body and a plurality of heat dissipation fins. The heat dissipation fins are arranged on the inner wall of the heat dissipation body in the circumferential direction at intervals. The structure of the radiator with the built-in fins is characterized in that a first heat dissipation groove is formed in the front end portion of the heat dissipation body, wherein the first heat dissipation groove penetrates through the inside of the heat dissipation body and communicates the inside and the outside of the heat dissipation body, a second heat dissipation groove is formed in the back end portion of the heat dissipation body, wherein the second heat dissipation groove penetrates through the inside of the heat dissipation body and communicates the inside and the outside of the heat dissipation body. The first heat dissipation groove is communicated with the second heat dissipation groove. The structure of the radiator with the built-in fins has the advantages that due to the fact that the first heat dissipation groove and the second heat dissipation groove are formed in the heat dissipation body, and the first heat dissipation groove is communicated with the second heat dissipation groove, when heat is accumulated inside the heat dissipation body, convection current can be formed between the first heat dissipation groove and the second heat dissipation groove, the heat can outflow from the heat dissipation body from the first heat dissipation groove and the second heat dissipation groove, the radiator with the built-in fins is good in heat dissipation effect and high in heat dissipation effect, and further prolongs the service lives of light-emitting diode (LED) lamps.
Description
Technical field
The utility model relates to a kind of heat spreader structures of built-in fin.
Background technology
The radiator of existing LED light fixture, as shown in Figure 1, its radiating fin 100 ' is built in heat radiator body 200 ', and the surface is even surface outside this heat radiator body 200 ', compared to the external radiator of radiating fin 100 ', this radiator outward appearance is more brief, attractive in appearance.But, the radiator that this radiating fin 100 ' is built-in, because heat radiator body 200 ' internal surface area increases, cause heat in heat radiator body 200 ', to form circulative convection and need the long period could discharge outside the heat radiator body 200 ', radiating efficiency is low, and heat radiator body 200 ' temperature is raise and influences the use of light fixture.
The utility model content
The utility model provides a kind of heat spreader structures of built-in fin, and it has overcome the existing deficiency of background technology.The technical scheme that adopts that the utility model solves its technical problem is: a kind of heat spreader structures of built-in fin, it comprises heat radiator body (100) and some radiating fins (200) of a hollow, described radiating fin (200) circumferentially is disposed on wall within the heat radiator body (100), it is characterized in that: heat radiator body (100) end before is provided with first radiating groove (300) that runs through outer within the heat radiator body (100), heat radiator body (100) end afterwards is provided with second radiating groove (400) that runs through outer within the heat radiator body (100), and first radiating groove (300) is connected second radiating groove (400).
Among one preferred embodiment: described first radiating groove (300) is annular.
Among one preferred embodiment: described second radiating groove (400) extends to the end face of heat radiator body (100) rearward end.
Among one preferred embodiment: described second radiating groove (400) number is made as a plurality of and annular space is arranged.
Among one preferred embodiment: the lateral dimension of described heat radiator body (100) is little from preceding gradual change then.
The technical program is compared with background technology, and it has following advantage:
1. heat radiator body is provided with first radiating groove and second radiating groove, and first radiating groove is connected second radiating groove, when the heat radiator body inner accumulated has heat, owing to can form convection current between first radiating groove and second radiating groove, make heat to flow out heat radiator body by first radiating groove and second radiating groove, make that this radiator heat-dissipation is effective, radiating effect height, and then the service life of prolongation LED light fixture.
2. first radiating groove is annular, makes convection channel bigger, and radiating effect is better.
