[0013] The present invention also provides a method for recovering heat energy of a lithium battery conductive coating. The method comprises the following steps:

[0014] Step 1: Use an external air pump to input cold water into the water inlet pipe.

[0016] Step 3: During the process, the temperature monitoring component monitors the temperature of the water in the insulation box. When the temperature rises to the set value, the hot water in the insulation box is discharged to the outside through the drainage component. At the same time, the one-way valve opens and cold water enters the insulation box. The water temperature in the insulation box is then reduced. Repeat steps 1 and 2 to continuously exchange heat between the copper heat conducting plate and the water.

[0017] Preferably, the front end of the rack is meshed with the rear ends of the two spur gears.

[0018] Beneficial effects

[0019] The present invention provides a heat recovery system and method for a lithium battery conductive coating. Compared with the prior art, it has the following advantages:

[0020] 1. A recovery method for a heat energy recovery system of a lithium battery conductive coating. Through the mutual cooperation between a copper heat conducting plate, a water flow driving component, a temperature monitoring component and a drainage component, the water flow driving component is activated by utilizing the change in temperature difference to stir the cold water in the insulation box, causing the higher temperature water around the copper heat conducting plate to flow to the other side, thereby allowing the water of different temperatures in different areas of the insulation box to be fully mixed. The water will not flow out if the temperature does not reach the set value, thereby allowing the water to fully exchange heat with the copper heat conducting plate, thereby improving the heat exchange efficiency.

[0021] 2. A recovery method for a heat energy recovery system of a lithium battery conductive coating, wherein mercury, a conductive contact, an anti-rust iron block and an electromagnet block cooperate with each other. When the water temperature rises to a set value, the volume of the mercury increases and contacts the corresponding conductive contact, thereby conducting the circuit among the mercury, the conductive contact, the backup battery, the electromagnet block and the one-way valve. The electromagnet block uses magnetic force to adsorb the anti-rust iron block, so that the hot water in the insulation box can be discharged to the required location through the drainage component, and the cold water flows into the insulation box through the manifold, realizing automatic water inflow and outflow and heat energy recovery.

[0022] 3. A recovery method for a heat recovery system of a lithium battery conductive coating. Through the coordination of a screw rod, a square insulating cover, a through hole and a marking line, the height of the through hole is adjusted to expose the conductive contact piece at the corresponding height, thereby realizing flexible adjustment of the water temperature setting value. When the water temperature reaches this setting value, the circuit in the electromagnet block can be turned on, which is highly practical.

[0023] 4. A recovery method for a heat recovery system of a lithium battery conductive coating. Through the cooperation between the filter mesh ball, the shaft, the arc-shaped brush and the arc-shaped blades, the cold water entering the insulation box can be filtered in advance to prevent impurities from entering the insulation box and adhering to the surface of the copper heat conduction plate. At the same time, the water flow is used to drive the arc-shaped brush to rotate, sweeping and scraping the surface of the filter mesh ball to avoid the adhesion of impurities and keep it unobstructed.

The upper and lower parts of the circular baffle 76 are fixedly provided with rust-proof iron blocks 77. The upper and lower parts of the inner cavity of the placement box 72 are fixedly provided with electromagnet blocks 78. The intercepting component 8 includes a accommodating ball 81, which accommodates the ball 8 1 is fixed with a connecting pipe 82 in the middle of the top, and the top of the connecting pipe 82 is fixedly connected to the bottom of the insulation box 1. A filter mesh ball 83 is fixedly provided at the bottom of the connecting pipe 82, and a shaft 84 is rotatably provided in the middle of the bottom of the filter mesh ball 83. Arc-shaped brushes 85 are fixedly provided on the upper left and right sides of the shaft 84. The top of the arc-shaped brush 85 contacts the bottom of the filter mesh ball 83.

A storage cylinder 87 is fixed in the middle of the bottom of the accommodating ball 81, and a sealing plug 88 is penetrated by the bottom thread of the storage cylinder 87.

[0040] Through the cooperation between mercury 64, conductive contact 65, rust-proof iron block 77 and electromagnet block 78, when the water temperature rises to the set value, the volume of mercury 64 increases and contacts the corresponding conductive contact 65, so that the circuit between mercury 64, conductive contact 65, backup battery 12, electromagnet block 78 and one-way valve 11 is connected, and electromagnet block 78 uses magnetic force to adsorb rust-proof iron block 77, so that the hot water in the insulation box 1 can be discharged to the required position through drainage assembly 7, and cold water flows into the insulation box 1 through the confluence pipe 9, realizing automatic water inlet and outlet recovery of heat energy, through screw rod 661, square insulating cover 662, through hole 663 and mark The lines 665 cooperate with each other to adjust the height of the through hole 663 so that the conductive contact 65 of the corresponding height is exposed, thereby realizing flexible adjustment of the water temperature setting value.

At the same time, the water flow is used to drive the arc-shaped brush 85 to rotate, sweeping the surface of the filter mesh ball 83 to prevent impurities from adhering to it, so that it remains unobstructed.

[0041] An embodiment of the present invention further provides a method for recovering heat energy of a lithium battery conductive coating using a system for recovering heat energy. The method comprises the following steps:

[0042] Step 1: Use an external air pump to input cold water into the water inlet pipe 10. The left and right one-way valves 11 are opened, and the cold water flows into the receiving ball 81 through the flow confluence pipe 9. The filter mesh ball 83 traps impurities in the receiving ball 81. Clean water passes through the filter mesh ball 83, flows through the connecting pipe 82, and then enters the insulation box 1, and is finally discharged to the outside through the drainage component 7. During this process, the heat generated by the operation of the lithium battery 2 is transferred to the conductive coating, and the conductive coating transfers the heat to the copper heat conducting plate 3. The copper heat conducting plate 3 contacts the cold water in the insulation box 1 to realize heat exchange. The water temperature gradually increases, and the temperature of the copper heat conducting plate 3 gradually decreases, thereby realizing heat energy recovery from the conductive coating on the lithium battery 2.

[0043] Step 2: Since nickel-titanium alloy is a common thermo-induced shape memory alloy and also a temperature-sensitive material, the volume of the nickel-titanium alloy strip 57 changes with the change of the water temperature in the incubator 1 during the process. When the temperature around the nickel-titanium alloy strip 57 gradually increases, the nickel-titanium alloy strip 57 expands and becomes longer upward, pushing the rack 54 upward, the spur gear 52 rotates, and the auger 51 rotates accordingly, pushing the water away from the copper heat conducting plate 3 to the side close to the copper heat conducting plate 3. When the temperature around the nickel-titanium alloy strip 57 gradually decreases, the nickel-titanium alloy strip 57 returns to its initial state and becomes shorter downward. Under the elastic action of the first spring 56, the rack 54 moves downward, and the auger 51 rotates in the opposite direction to continue stirring the water in the incubator 1.

[0044] Step 3. During the process, the temperature monitoring component 6 monitors the temperature of the water in the insulation box 1. When the temperature rises to the set value, the volume of the mercury 64 increases and contacts the corresponding conductive contact 65 through the through hole 663. Since the mercury 64, the conductive contact 65, the backup battery 12, the electromagnet block 78 and the one-way valve 11 are electrically connected through the wire, the circuit between the mercury 64, the conductive contact 65, the backup battery 12, the electromagnet block 78 and the one-way valve 11 is now conductive, and the electromagnet block 78 is energized, and the rust-proof iron block 77 is adsorbed by magnetic force, so that the hot water in the insulation box 1 can be discharged through the drainage component 7 and supplied to the required position, and the cold water flows into the insulation box 1 through the connecting pipe 9, realizing automatic water inlet and outlet, and the water temperature in the insulation box 1 is reduced again. The operations of steps 1 and 2 are repeated to continuously exchange heat between the copper heat conducting plate 3 and the water to recover heat energy.
