On the contrary, convective phenomena of the coolant 2 occur, such as the cold coolant 2 on the upper side move to the lower side. This phenomenon is similar to a phenomenon in which the lid of the kettle is shaken when the water in the kettle is heated by using a burner and the water rises upward.

The convection phenomenon as described above is further accelerated by the heat pipe 310.

Accordingly, the heat of the coolant 2 and the heat pipe 310 according to the convection of the coolant 2 and the heat movement of the heat pipe 310 is transferred through the protrusion 110 to the coolant pipe 1 and the coolant pipe ( It is cooled by the refrigerant 2 in 1).

This is to allow heat generated from the LED lighting located in the second housing 100b to be transferred toward the first housing 100a through the second heat pipe 730. Since the fixing of the second heat pipe 730 is the same as fixing the heat pipe 310, a description thereof will be omitted.

The thermal conductive auxiliary member 320 is configured between the second heat pipe 730 and the first housing 100a.

The second heat pipe 730 is formed in the longitudinal direction of the coolant pipe 1 while contacting the auxiliary member 320 for heat conduction of the first housing 100a. Thus, after quickly transferring heat from one side of the second heat pipe 730 to the other side, the heat cooling efficiency may be improved by transferring the heat to the cooling water pipe 1.

Hereinafter, the description of the configuration and fastening method, the separation prevention means, the packing 400, etc. of the LED lighting lamp 200 is the same as described above will be omitted here.

The thermal cooling principle of the LED lighting lamp 200 according to the second embodiment of the present invention configured as described above will be described.

First, when power is supplied, high heat is generated as light is emitted from the LEDs 221 of the plurality of LED lighting lamps 200.

The heat is transferred to the second housing 100b through the applied grease 710.

The temperature rises due to the heat generated by the LED 221 throughout the second housing 100b of FIG. 14, and the heat is generated by the second heat pipe 730 through the refrigerant 2 and the refrigerant 2. Is transferred toward the cold side and moves rapidly toward the cold side (the part in contact with the protrusion 110) due to the nature of the heat pipe.

At this time, the temperature of the refrigerant 2 in the second housing 100b gradually rises and boils due to the heat transferred from the LED 221, and the refrigerant 2 having the temperature increased gradually increases in the first housing 100a of the upper side. To the side. On the contrary, convective phenomena of the coolant 2 occur, such as the cold coolant 2 on the upper side move to the lower side.

The convection phenomenon as described above is further accelerated by the second heat pipe 730.

Accordingly, as the convection of the refrigerant 2 and the heat movement through the second heat pipe 730, the heat of the refrigerant 2 and the second heat pipe 730 is transferred to the cooling water pipe through the protrusion 110. 1) and the refrigerant 2 in the cooling water pipe 1.

Particularly, in the present invention, heat is quickly transferred from one side of the second heat pipe 730 formed in the longitudinal direction of the cooling water pipe 1 to the other side while being in contact with the auxiliary member 320 for heat conduction, and then transferred to the cooling water pipe 1. Thus, heat dissipation efficiency is improved. Thus, the present invention is significantly improved thermal cooling efficiency compared to the case where the second heat pipe 730 is not provided.

In an embodiment of the present invention, the second housing 100b is configured to be positioned below the first housing 100a, but is not limited thereto. That is, the second housing 100b may be configured to be located above the first housing 100a.

LED lighting lamp cooling apparatus of the present invention can be installed in any place (eg, rest area, signage, etc.) that the LED lighting lamp 200, such as stadiums such as football or baseball field that is operated on a large scale, as well as street lamps or lights operated on a small scale. have.

As described above, with reference to the preferred embodiment of the present invention, those skilled in the art will be variously modified and modified within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below.
