[0017] like Figure 1 and Figure 2 As shown, this embodiment provides a water-cooled heat dissipation structure for underwater electronic devices. The water-cooled heat dissipation structure achieves liquid circulation heat dissipation through a micro water pump, including:
[0018] Electronic compartment 1 is the main structure of the watertight compartment, and electronic compartment 1 houses liquid cooling heat dissipation device 2 and circuit board 6, with openings on the side and a sealing structure 3.
[0019] like Figure 3 As shown, the liquid cooling heat dissipation device 2 includes a water cooling plate 2.1, a liquid cooling pipe 2.2, and a micro water pump 2.3. The water cooling plate 2.1 is mounted on the chip of the circuit board 6, the liquid cooling pipe 2.2 is welded and laid flat on the water cooling plate 2.1, the micro water pump 2.3 is located at the water inlet 7 at one end of the liquid cooling pipe 2.2, and the other end of the liquid cooling pipe 2.2 is the water outlet 8.
[0020] Specifically, the sealing structure 3 includes a sealing plate 5, a sealing ring, and screws. The sealing plate 5 is assembled with the side opening of the sealed electronic compartment 1 by screws and the sealing ring. The liquid cooling pipe 2.2 passes through the sealing structure 3 during the assembly process.
[0021] Specifically, a thermal interface material 4 is provided between the circuit board 6 chip and the water-cooled plate 2.1 to reduce air thermal resistance.
[0022] Specifically, the inlet 7 of the liquid cooling heat dissipation device 2 is connected to the water source of the working environment where the equipment is located.
[0023] Specifically, the power supply terminal of the micro water pump 2.3 is connected to the power supply inside the underwater electronic equipment compartment.
[0024] In the water-cooled heat dissipation structure described in this embodiment, when the temperature of the circuit board chip rises during the operation of the underwater electronic equipment, the micro water pump 2.3 is activated. The water pump introduces water from the working environment of the equipment. The water flows into the liquid cooling pipe 2.2 through the inlet 7, and dissipates heat from the circuit board 6 chip, which is fitted with the water cooling plate 2.1 and coated with thermal interface material 4, through the liquid cooling pipe 2.2 welded to the water cooling plate 2.1. The heated water is then discharged directly outside the chamber through the outlet 8 at the other end of the pipe. This continuous liquid flow process carries the heat from the chip out of the chamber, achieving the purpose of reducing the chip temperature. The electronic chamber 1 has a watertight structure to ensure the normal operation of the equipment underwater. The sealing structure 3 effectively prevents water from entering the chamber and damaging the equipment, and the thermal interface material 4 reduces air thermal resistance and improves heat dissipation efficiency.
