[0030] Example 1

[0031] Please see Figures 1-5 The present invention provides an embodiment of a water-cooled radiator heat dissipation system for high-brightness projection equipment, comprising a heat exchange device 2 for heat exchange and support.

[0032] The fan housing 5 has two sets, and both sets of fan housing 5 are fixedly installed at the front of the heat exchange device 2. The four corners of the inner end face of the fan housing 5 are provided with positioning holes 1. The fan module 4 is provided on the inner end face of the fan housing 5. The fan housing 5 is used for air cooling.

[0033] Water cooling device 3 is fixedly installed on the side of the front end face of heat exchange device 2. Water cooling device 3 is used for heat conduction and circulation.

[0034] The heat exchange device 2 includes a water-cooled radiator housing 23. Heat dissipation fins 24 are equidistantly arranged on the inner end face of the water-cooled radiator housing 23. Four sets of alignment holes 25 are symmetrically arranged on the inner end face of the water-cooled radiator housing 23. Two sets of positioning guide tubes 22 are arranged on the side of the front end face of the water-cooled radiator housing 23. A connecting tube 21 is arranged on the lower part of the front end face of the water-cooled radiator housing 23 near the positioning guide tubes 22.

[0035] The interior of the water-cooled radiator housing 23 is hollow, and the connecting pipe 21 and the positioning conduit 22 are both connected to the interior of the water-cooled radiator housing 23. The connecting pipe 21 can be easily connected and assembled with other water-cooled radiator housings 23 to improve heat dissipation efficiency.

[0036] The positioning hole 1 and the alignment hole 25 are coaxially set. The fan housing 5 is fixedly set at the front of the water cooling radiator housing 23 by matching the positioning hole 1 and the alignment hole 25, which can facilitate the quick assembly and disassembly maintenance of the fan housing 5 in the future.

[0037] The water cooling device 3 includes a circulating pump 32, which has a PWM speed regulation function and can adjust the flow rate according to temperature changes, saving energy and keeping the noise low. Coolant conduits 31 are symmetrically arranged in the middle of the rear end face of the circulating pump 32, and a water cooling head 33 for heat absorption is arranged in the front of the circulating pump 32. Four sets of limiting grooves 34 are equidistantly arranged on the side end faces of the circulating pump 32 and the water cooling head 33. The water cooling head 33 is located in a high heat source area, such as a light source module or an optomechanical area, and is made of a high thermal conductivity material. It also has an internal microchannel structure to improve heat exchange efficiency.

[0038] The coolant conduit 31 is sealed on the outside of the positioning conduit 22, which is pagoda-shaped, allowing for quick disassembly and docking of the coolant conduit 31 and the positioning conduit 22.

[0039] The water-cooling radiator housing 23 is made of aluminum. The water-cooling radiator housing 23 has water-cooling channels inside, and the heat dissipation fins 24 are configured in parallel with the water flow channels. The water-cooling radiator housing 23 is installed on the outside or bottom of the projector housing and has a quick-installation and removal mechanism. The heat dissipation fins 24 are configured in parallel with the water flow channels. The water flow channels adopt a dual-loop or circulating design to distinguish between high-heat and low-heat areas, thereby optimizing heat dissipation efficiency. The number of radiators can be adjusted according to heat dissipation requirements to improve the adaptability of the equipment. The external control module can dynamically control the pump and fan speed through temperature sensors and supports remote monitoring and alarm functions.

[0040] A 10,000-lumen laser engineering projector using the water-cooled radiator heat dissipation system of this invention maintained the temperature of the light source module below 60°C after 8 hours of continuous operation. Compared with the traditional air-cooled system, the cooling efficiency was improved by about 35%, and the noise of the whole machine was reduced by 10dB, which verifies the feasibility and superiority of the technology of this invention.

[0041] A water-cooled radiator heat dissipation method for high-brightness projection devices includes the following steps:

[0042] S1: When the device is started, the external control module judges the output value inside the temperature sensor projector, and then drives the circulation pump 32 to start liquid circulation;

[0043] S2: The coolant absorbs heat from the high-heat module through the water block 33 and is circulated by the circulation pump 32, so that the coolant with heat energy flows into the water radiator housing 23 and then releases heat energy to the outside air.

[0044] S3: The overall circulation is maintained within the optimal flow rate and temperature difference range to ensure stable operation of the system over a long period of time.

[0045] Working principle: such as Figure 5Before use, the operator can lock the water cooling head 33 to the high-heat module of the projector with bolts. When the projector is working, its internal heat sensor can detect the module. When the set heat value is reached, the circulation pump 32 is started. The circulation pump 32 can drive the liquid to circulate between the circulation pump 32 and the water cooling radiator housing 23. The cooling system inside the circulation pump 32 can absorb the heat energy of the high-heat module in the water cooling head 33. Then, it is introduced into the water cooling radiator housing 23 through the coolant conduit 31. The water cooling radiator housing 23 can dissipate heat from the coolant through the internal water cooling channel, heat dissipation fins 24 and fan module 4.
