Description

  The present invention relates to an improved structure of a heat radiator, and in particular, by directly molding a heat radiator made of a plastic material and enclosing the heat conduit, the heat conduit is brought into direct contact with a heat source, thereby effectively increasing the heat conduction effect and cost. The present invention relates to an improved structure of a radiator that can reduce the weight.

  The usage rate of electronic information products (for example: computers, etc.) is spreading day by day and is widely applied. As the needs increase, the technology of the electronic information industry will rapidly develop, the speed of electronic information calculation will increase, the access dose will increase, etc., so that the components incorporated in the electronic information product will generate high temperature when operating at high speed become.

  Light-emitting diodes (LEDs) are cold-emitting, and have such characteristics as low consumption of electricity, long life of components, little contamination, no need for warm-up time, fast reaction speed, and high efficiency. Further, when a brighter light illuminance is required, such as a streetlight or a lighting device, a brighter light illuminance can be obtained by generally adopting a high-efficiency light emitting diode and flowing a relatively high current.

  However, it is unavoidable to increase the amount of heat energy at the same time as increasing the light intensity. If the heat energy generated immediately is not discharged, accumulation of heat around the light emitting diode will reduce the light emitting efficiency and affect the life of the light emitting diode. While there are many electronic equipments that use LEDs as the main light source, there is a common disadvantage that the heat dissipation effect is universally poor, so the electronic equipment that uses these LEDs as the main light source burns due to overheating, and the luminous efficiency tends to decline. It brings about the disadvantage of shortening the service life.

  1 and 2 are a three-dimensional view and a cross-sectional view of a conventional heat radiator. In this figure, the radiator 1 is a radiator 11 processed and manufactured mainly of aluminum or a single metal material. The radiator 11 has a hollow cylindrical body, and a plurality of radiators are disposed outside and inside the radiator 11. The fin 12 is stretched. The heat radiating fins 12 are made of the same single metal material as the heat radiating body 11, and are integrally formed with the heat radiating body 11. Since the radiator 11 and the radiator fin 12 are made of a metal material, the material cost is high and the weight is heavy. When the heat radiator 1 is used for an LED module to dissipate heat, the LED module is provided at the edge of one end of the heat dissipator 11 and heat is dissipated through the heat dissipator 11 and the heat dissipating fins 12. However, since the heat radiating body 11 and the heat radiating fin 12 use a single metal material, the heat conductivity is relatively poor, and the heat energy of the LED module cannot be effectively conducted.

In summary, the prior art has the following disadvantages:
1. Low heat transfer efficiency.
2. Material costs are high.
3. Heavy material.
In view of the above drawbacks, further improvements were necessary.

3 and 4 show an improved structure of a radiator according to an embodiment of the present invention.
The present invention includes a heat radiating body 2 and a heat conduit 3, and since the heat radiating body 2 is injection-molded using a plastic material, the outer shape can be various shapes based on needs. In this embodiment, the heat radiating body 2 is formed in a hollow cylindrical body, and mainly includes a covering portion 21. The covering portion 21 has a flat first end surface 22 and a second end surface 23 at both ends, respectively, and the covering portion 21 uses a plastic material on both the inside and outside between the first end surface 22 and the second end surface 23. A plurality of fins 24 to be injection-formed are formed. The heat conduit 3 is installed inside the radiator 2 through a plastic material injection molding method. The heat conduit 3 has a first end edge 31, an extending portion 32, and a second end edge 33, and the extending portion 32 is installed between the first end edge 31 and the second end edge 33.

  In the present embodiment, the extending portion 32 of the heat conduit 3 extends between the first end edge 31 and the second end edge 33 by a spiral method, respectively, and the first end edge 31 and the second end edge 33 are respectively dissipated in the heat dissipation. It is installed on the first end face 22 and the second end face 23 of the body 2 and exposed from each end face. The heat radiator 2 is injection-molded using a plastic material, and the heat conduit 3 is made of a copper metal material. That is, if a material having a melting temperature lower than that of the heat conduit 3 is selected, the heat radiator 2 can be covered outside the heat conduit 3. In this embodiment, the heat radiating body 2 is made of a plastic material, but is not limited thereby.

  As shown in FIGS. 5, 6, and 7, the radiator 2 can be connected to the LED module 4. The LED module 4 can be installed on one of the first end surface 22 or the second end surface 23. In this embodiment, the LED module 4 is installed on the second end surface 23 and attached. The second end edge 33 of the heat conduit 3 is exposed from the second end face 23, and the second end face 23 is simultaneously attached to the LED module 4 and attached thereto. When the LED module 4 generates heat, it absorbs heat directly through the second edge 33 of the heat conduit 3 and then sends the heat to the first edge 31 through the extending portion 32.

  Further, since the radiator 2 covers the first end edge 31, the extending portion 32, and the second end edge 33, the second end edge 33 absorbs heat, and the extending portion 32 and the first end edge 31 are absorbed. High heat conduction effect is achieved because it can be quickly transmitted to and dissipated through the radiator 2. Further, since the heat radiator 2 is injection-molded using a plastic material, and the heat conduit 3 is covered with the heat radiator 2 by injection molding, the heat absorbed by the heat conduit 3 is more effectively discharged. And at the same time reduce the overall weight and save material costs.
