[0015] Example

[0016] like Figure 1 and Figure 2As shown, a heat dissipation water tank device includes a water tank 1, which is used to store cooling water. The water tank 1 is semi-cylindrical in shape and is made of aluminum alloy sheet metal that is bent and welded, with a wall thickness of 1 mm. And the welding position is sealed to ensure its water tightness; a water tank bracket 2 is installed at the bottom of the water tank 1, and the water tank bracket 2 is an aluminum alloy bracket, which fixes the water tank to the aircraft and keeps a certain distance between the water tank and the aircraft structure, so as to prevent the aircraft from keeping the water tank stable when deforming. The water tank bracket 2 includes four bracket units, which are respectively installed on both sides of the bottom of the water tank 1. The bracket unit includes a leg 9. The leg 9 is a hollow structure, which can reduce the weight of the bracket on the basis of maintaining the structural strength. The leg 9 is provided with an air hole 10 at the bottom, through which the air hole 10 can ensure that the air flow enters the leg 9 to dissipate heat, so as to quickly dissipate the heat taken away after the coolant circulates; the top of the leg 9 is an arc-shaped structure, and an arc plate 11 is installed on the side of the leg 9. The top of the leg 9 and the arc plate 11 are attached to the water tank 1 and welded, and the arc plate 11 strengthens the connection strength between the leg 9 and the water tank 1; a water injection port 3 is installed at the top of the water tank 1, and the water injection port 3 is threadedly connected to the tank cover. The water injection port 3 is the position where the water tank 1 is injected with coolant, and at the same time, excess gas can be discharged. Its shape is a circular external threaded port. When filling water, unscrew the box cover to fill water, and screw the box cover on when using it. Exhaust is achieved by setting a pressure relief device on the box cover. The water inlet 3 is connected to the water tank 1 by threaded connection and sealed with a rubber ring; the front end of the water tank 1 is equipped with a water inlet pipe 4 and a connecting pipe 8, and the water inlet pipe 4 is located above the connecting pipe 8 to prevent the coolant from flowing fully when the aircraft is maneuvering. The connecting pipe 8 is connected to the input end of the water pump 6, and the output end of the water pump 6 is connected to the water outlet pipe 5. The water pump 6 provides power for the liquid cooling cycle to make the coolant flow. The energy source of the water pump 6 is low-voltage electricity, and its flow rate and flow rate are determined according to the needs of the aircraft liquid cooling system; the water pump 6 is provided with a fixed sleeve 12, and the bottom of the fixed sleeve 12 is fixed to the water pump bracket 7 by bolts; the water pump bracket 7 is used to fix the water pump 6 and connect the water pump 6 with the water tank 1.
