DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The present invention provides an efficient heat dissipation system for an LED module, comprising an LED light source module 1, a heat sink and a heat pipe 2. The heat sink is provided with a plurality of heat sinks 3, and the heat pipe 2 is connected to the heat sink; the heat sink 3 can specifically adopt the heat dissipation fins of the prior art, and the heat pipe 2 is a metal pipe with good thermal conductivity. The heat sink 3 and the heat pipe 2 of the present invention are both prior art and will not be described in detail here. In addition, the present invention further comprises a housing 4, a flat fan 5, a longitudinal air inlet fan 6 and a longitudinal air outlet fan 7. The interior of the housing 4 is provided with a receiving cavity, and the heat sink and the heat pipe 2 are both received in the receiving cavity. The LED light source module 1 and the flat fan 5 are spaced apart on the top outer wall of the housing 4. The bottom of the LED light source module 1 is connected to the receiving cavity through a through hole.

The longitudinal air inlet fan 6 and the longitudinal air outlet fan 7 are both arranged corresponding to the heat sink 3 and are both connected to the receiving cavity.

[0024] It can be understood that the above-mentioned LED light source module 1 includes components such as an LED light source and a lens 14.

The LED light source module 1 of the present invention is an existing technology and will not be described in detail here.

[0025] The heat dissipation principle of the present invention is as follows: when working, the LED light source at the bottom of the LED light source module 1 will generate more heat, and the heat will enter the receiving cavity of the shell 4, and the heat pipe 2 and the heat sink 3 of the heat sink will absorb the above-mentioned heat of the LED light source module 1 entering the shell 4; further, the heat in the shell 4 is dissipated through a two-way fan heat dissipation system: one way is a heat dissipation system in which a flat fan 5 directly blows the heat pipe 2, which draws air from the outside into the shell 4 through the flat fan 5 to blow air and dissipate heat to the heat pipe 2; the other way is a one-in-one-out strong convection heat dissipation system in which a longitudinal air inlet fan 6 and a longitudinal air outlet fan 7 directly blow the heat sink 3, which draws air into the shell 4 through the longitudinal air inlet fan 6 and blows the heat in the receiving cavity such as the heat brought out by the flat fan 5 and the heat brought out by the longitudinal air inlet fan 6 from the inside of the shell 4 to the outside through the longitudinal air outlet fan 7, thereby realizing heat dissipation of the receiving cavity of the shell 4, that is, realizing the cooling of the heat of the LED light source module 1.

[0026] Preferably, the rotation speed of the longitudinal air outlet fan 7 is greater than the rotation speed of the longitudinal air inlet fan 6 to balance the air volume of the tiling fan 5.

The upper connecting portion 11 is arranged in the first slot 10, and the lower connecting portion 12 is arranged in the second slot. The curved portion 13 connects the upper connecting portion 11 and the lower connecting portion 12, meaning that one heat pipe 2 is connected to both heat sinks 8 and 9. The curved portion 13 protrudes relative to the first heat sink 8 and the second heat sink 9. There are multiple heat pipes 2, and heat pipes 2 are distributed on both sides of the first heat sink 8 and the second heat sink 9. Multiple heat pipes 2 on the same side are spaced apart.
