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. ...

Embodiment 3

[0054] This embodiment also provides a 3D printing-based LED heat dissipation headlight for vehicles, including a heat dissipation reflector 1, an LED light source module 3 installed on the inner bottom of the heat dissipation reflector 1 through a heat-conducting silica gel 2, and a heat dissipation reflector 1 The light source lens 4 at the mouth of the cup and the heat dissipation reflector 1 adopt the heat dissipation reflector 1 of the second embodiment above.

[0055] A lens installation hole 14 is opened on the end surface of the heat dissipation reflector 1 near the light source lens 4 , and the light source lens 4 is installed on the heat dissipation reflector 1 through the lens installation hole 14 .

[0056] The inner bottom of the heat dissipation reflective cup 1 is provided with an LED light source installation hole 16 , and the LED light source module 3 is installed on the inner bottom of the heat dissipation reflective cup 1 through the LED light source installa...

Abstract

The invention discloses a vehicle LED lamp based on 3D printing and a liquid cooling system thereof used for the vehicle LED lamp, relates to the field of vehicle LED illumination, and aims to provide a vehicle LED lamp based on 3D printing and a liquid cooling system thereof. A radiator comprises a shell, a liquid injection port and a liquid outlet are formed in the shell, a middle jet plate is arranged in the shell and divides an inner cavity of the shell into a micro-jet high-pressure liquid inlet area and a heat exchange area, the heat exchange area comprises a micro-jet cooling cavity and a porous medium heat dissipation channel, the micro-jet high-pressure liquid inlet area and the porous medium heat dissipation channel are both communicated with the liquid injection port, the micro-jet high-pressure liquid inlet area is communicated with the micro-jet cooling cavity through micro-jet small holes in the middle jet plate, and the micro-jet cooling cavity, the porous medium heat dissipation channel and the liquid outlet are sequentially communicated. According to the radiator, the radiating efficiency of the vehicle LED lamp is remarkably improved, and the service life of a headlamp of a vehicle body is prolonged.

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...
