Embodiment 1

[0017] Example 1, such as figure 2 As shown, a radiator for an LED lamp holder, the radiator is provided with a metal heat dissipation substrate 1, as a preferred embodiment, one side of the substrate 1 is the installation surface 11 of the LED lamp holder, in order to facilitate the installation and fixing of the LED lamp, on the installation surface 11 Mounting holes 15 are provided on the top; the other side of the substrate 1 is a heat dissipation surface 12, and the heat dissipation surface 12 is provided with graphite heat dissipation fins 2. When graphite is heated, it has a good heat radiation effect, and the substrate 1 is provided on the upper heat dissipation surface 12. There are connection holes 16 for pressing the graphite heat dissipation fins 2, so as to be used for connection when pressing the graphite heat dissipation fins 2, so that the two are firmly connected and not easy to separate.

Embodiment 2

[0018] Example 2, such as image 3 As shown, in this embodiment, the heat dissipation surface 12 of the heat dissipation substrate 1 is provided with a "T"-shaped raised heat dissipation part 13, and the graphite heat dissipation fins 2 are arranged on the raised heat dissipation part 13, and a "T" is set In this embodiment, the heat dissipation substrate 1 is provided with a hollow cavity 14, and the hollow cavity 14 is filled with a heat dissipation liquid 3, and the heat dissipation substrate 1 forms a heat dissipation conduit , the liquid in the heat dissipation pipe can form strong convection in addition to direct heat conduction when heated, and can quickly transfer the heat generated by the circuit chip to the heat dissipation fin 2 made of graphite, and through the graphite heat dissipation fin 2 Heat can be transferred over a large area through convection and heat radiation. The upper heat dissipation surface 12 of the substrate 1 is provided with connection holes 16...

Abstract

The invention relates to the technical field of electronic cooling devices, in particular relates to a heat sink for an LED (light-emitting diode) lamp holder. The heat sink for the LED lamp holder is characterized by comprising a metal heat dissipation base plate, the other side of the base plate is a heat dissipation surface, the heat dissipation surface is provided with a graphite heat dissipation fin, when an LED lamp is arranged on the heat sink, heat produced by a chip is conducted onto the metal base plate, the metal base plate rapidly conducts the heat to the graphite heat dissipation fin, the heat conducted to the fin can be lost in a convection current manner and a radiation manner as graphite has good thermal radiation effect, and the heat produced by a chip of an LED circuit board can be effectively conducted away even in poor airflow or airtight environment, and a phenomenon that the LED lamp is invalid owning to overheating can be avoided, thus the service life of the LED lamp is prolonged; and hidden troubles, such as a fire, caused by overheating can be avoided.

Description

technical field [0001] The invention relates to the technical field of electronic cooling equipment, in particular to a radiator for LED lamp holders. Background technique [0002] LED lamp is a new type of semiconductor solid light source, which has significant advantages such as low power consumption and long life. Under the circumstances of increasing global resource shortage and increasing environmental pressure, LED lighting has been recognized as an important way to save energy. [0003] LED light is a light-emitting diode controlled by a chip. The chip is set on the control circuit board. The chip will generate a lot of heat during operation. At present, the heat dissipation of the chip in the field of LED lights is a very important task. At present, the commonly used heat dissipation The heat sink is a copper or aluminum heat sink. One side of the heat sink is provided with an LED mounting surface 11, and the heat dissipation surface 12' on the other side is provide...
