Embodiment 1

[0038] A 3D printing-based radiator for LED lamps for vehicles, including a housing, a liquid injection port 121, a liquid outlet 122, a lamp fixing installation hole 123, a micro-spray high-pressure liquid inlet area 124, a micro-spray cooling chamber 125, and an intermediate jet plate 126, micro-spray holes 127, bottom cold plate 128, spherical through-hole porous medium 129, top cover plate 1210, spoiler column 1211, porous medium cooling channel 1212, porous medium liquid injection area 1213, cooling liquid output area 1214.

[0039]A lamp fixing installation hole 123 is opened on the shell, and the radiator 12 is installed on the outer bottom surface of the reflector cup through the lamp fixing installation hole 123 . A wiring hole 15 is also provided in the middle part of the housing axially, through which some cables required by the headlight can pass in and out. The shell includes a bottom cold plate 128 and a top cover plate 1210, and a cooling chamber is formed insid...

Embodiment 2

[0047] This embodiment also provides a 3D printing-based heat dissipation reflector cup for LED lamps for vehicles, which includes a cup body 11, and a radiator 12 is connected to the bottom surface of the cup body 11, and the radiator 12 adopts the radiator 12 in the first embodiment.

[0048] It also includes a plurality of ribs 13 connected to the cup body 11 , the plurality of ribs 13 are evenly distributed along the circumferential direction of the cup body 11 , and each rib 13 is arranged along the axial direction of the cup body 11 . During installation, the rib plate 13 is embedded into the corresponding slot of the car mounting frame. The rib plate 13 is used for positioning and strengthening, so that the whole reflector cup is embedded in the corresponding slot of the car mounting structure, preventing the car from reflecting light during driving. The vibration of the cup affects the lighting effect, and at the same time increases the intensity of the reflective cup. ...

Abstract

The invention discloses a 3D printing-based automotive LED lamp and its liquid cooling system, which are used for automotive LED lamps and relate to the field of automotive LED lighting. The purpose is to provide a 3D printing-based automotive LED lamp and its liquid cooling system. liquid cooling system. The radiator includes a shell, which is provided with a liquid injection port and a liquid outlet, and an intermediate jet plate is arranged in the shell, and the intermediate jet plate divides the inner cavity of the shell into a micro-spray high-pressure liquid inlet area and a heat exchange area. The area includes the micro-spray cooling cavity and the porous medium heat dissipation channel. The micro-spray high-pressure liquid inlet area and the porous medium heat dissipation channel are all connected to the liquid injection port. The cavity is connected, and the micro-spray cooling cavity, the porous medium heat dissipation channel, and the liquid outlet are connected in sequence. The radiator significantly improves the heat dissipation efficiency of the LED lamp for the vehicle, and improves the service life of the headlight of the vehicle body.

Description

technical field [0001] A 3D printing-based vehicle LED lamp and its liquid cooling system relate to the technical field of heat dissipation for LED lighting and are used for the illumination of vehicle LED lamps. Background technique [0002] LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. With the gradual maturity of LED technology, its advantages such as energy saving, low cost, long life, good durability, small component size, fast response speed, and low brightness attenuation have begun to attract attention. Therefore, the application of LED lamps in various industries is becoming more and more extensive. In the automotive industry, the application of LEDs in interior lighting, brake lights, emergency lights, and daytime running lights has achieved remarkable results. The proportion of LEDs in the interior and exterior lighting sources of the vehicle has exceeded 80%. [0003] At...
