Problems solved by technology

However, the design and appearance of the existing LED lamps are not in harmony with the original street light poles. If the LED street lamps are designed to look like the original high-pressure sodium lamps, heat dissipation will not be solved.

Embodiment Construction

[0027] Best practice:

[0028] The LED liquid-cooled heat dissipation structure is characterized in that: the heat generated by the LED 5 bonded on the aluminum or copper substrate is absorbed and conducted to the liquid heat dissipation medium 3 by the heat exchanger 6A that is closely attached to it, and the pipe 8 communicates with it. With the micro water pump 4, when the water pump is running, the liquid cooling medium 3 is driven to circulate in the expansion buffer 2 and the three heat exchangers 6A, 6B, 6C, and the heat generated by the LED is transferred to the heat exchanger 6B and the heat exchanger 6C In the middle, the shell of the lamp is closely attached to the heat exchanger 6B and the heat exchanger 6C, and the heat in the liquid cooling medium 3 is dissipated into the air by the shell of the lamp; The upper shell part 7 of the lamp is installed in close contact with the heat exchanger 6B.

[0029] At least one miniature water pump 4 is connected in series in...

Abstract

The invention relates to a light emitting diode (LED) liquid-cooling heat dissipation structure, which is characterized in that: the heat generated by a working LED (5) bound on an aluminum or copper substrate is absorbed by a heat exchanger (6A) tightly abutted with the LED (5) and is conducted to a liquid heat dissipation medium (3), a pipeline (8) is communicated with a mini-size water pump (4), the water pump drives the liquid heat dissipation medium (3) to circulate in an expansion buffer (2) and three heat exchangers (6A, 6B, 6C) in the running process, the heat generated by the working LED is conducted to the heat exchangers (6B, 6C), a light fitting outer shell is tightly abutted with the heat exchangers (6B, 6C), and the heat in the liquid heat dissipation medium (3) is dissipated into air through the light fitting outer shell; a street lamp shell dismounting part (1) is tightly abutted with and installed on the heat exchanger (6C), and a street lamp shell mounting part (7) is tightly abutted with and installed on the heat exchanger (6B). The invention has the advantages of good heat dissipation effect and more flexible design. In the invention, the large and heavy aluminum profile radiator is saved, and the cost is also saved.

Description

technical field [0001] The invention relates to an LED liquid-cooled heat dissipation structure. Background technique [0002] The LED light source is close to the surface light source, and the high-pressure sodium lamp is a columnar light source. In terms of the light utilization rate characteristics of the two lamps, the light utilization rate of the LED light source is higher than that of the high-pressure sodium lamp; The ground illumination is higher than that of high pressure sodium lamps. Now the luminous efficiency of LED lights can reach and exceed 110Lm / W, which has reached the level of luminous efficiency of high-pressure sodium light sources. Since the LED emits white light, the brightness of the intermediate vision of the human eye is higher; that is, under the same ground illuminance, the actual human eyes feel that the LED lamp is brighter than the high-pressure sodium lamp. So it is already feasible to replace high-pressure sodium lamps with LED lamps. How...
