Storage batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries.

[0003] Regarding the battery waste heat recovery device for new energy vehicles disclosed in the patent publication number "CN219191862U", the heat generated by the battery module during charging and discharging can be absorbed by several heat conduction plates in the heat energy recovery mechanism and stored in the heat exchange fluid inside the heat collection tube. However, as the use time increases, a large amount of dust will accumulate on the surface of the heat conduction plates and the heat collection tube. Dust is a poor heat conductor and will hinder the transfer of heat. The main function of the heat conduction plates and the heat collection tube is to transfer and collect heat. If the surface is covered with a large amount of dust, it will seriously affect its thermal efficiency and cause the performance of the equipment to decline. Accordingly, this application proposes a battery waste heat recovery device for new energy vehicles. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A battery waste heat recovery device for new energy vehicles includes a base plate 2, a cleaning plate 11 and a heat conducting plate 45. Four brackets 19 are fixedly connected to the upper end of the base plate 2. It should be noted that the base plate 2 can also protect the battery 1. When the car is driving on a bumpy road, the unevenness of the road and the damage to the battery 1 caused by pebbles can be reduced.

[0023] A heat storage tube 13 is fixedly connected to the heat conducting plate 12, wherein the heat energy stored in the heat storage tube 13 can be used as heat energy for air conditioning heating, seat heating, steering wheel heating and other functions. Figure 1 As shown, the battery 1 is fixedly mounted on the upper end of the bracket 19 and the lower end of the heat conducting plate 12. The heat generated by the battery 1 is absorbed by the heat conducting plate 12 and transferred to the heat storage tube 13 for storage. Two grooves 6 are symmetrically provided on the bottom plate 2. A guide mechanism for guiding the cleaning plate 11 is installed on the bottom plate 2. The guide mechanism includes two sliders 7. Each slider 7 slides in an adjacent groove 6. The width of the slider 7 is slightly smaller than the width of the groove 6.

[0024] The upper end of the cleaning plate 11 is fixedly connected with a first connecting handle 16, the first connecting handle 16 is rotatably connected with a second connecting handle 17, the lower end of the second connecting handle 17 is rotatably connected with a cam 14, the bottom plate 2 is fixedly connected with a box body 4, a rotating mechanism for rotating the cam 14 is installed in the box body 4, and a water cooling mechanism for heat dissipation of the battery 1 is fixedly installed on the bottom plate 2. The water cooling mechanism includes a guide rod 10, a piston cylinder 9, a piston 18, a water inlet pipe 8, a water outlet pipe 21, and a water bucket 15. One end of the guide rod 10 is fixedly installed on the slider 7, and the other end of the guide rod 10 is fixedly installed on the piston 18. The piston 18 is slidably connected in the piston cylinder 9, one end of the water inlet pipe is fixedly connected in the piston cylinder 9, the other end of the water inlet pipe 8 is fixedly connected in the water bucket 15, one end of the water outlet pipe 21 is fixedly connected in the piston cylinder 9, and the other end of the water outlet pipe 21 is fixedly connected to the bottom of the battery 1.

[0025] The rotating mechanism includes a motor 3 and a short rod 5. One end of the output shaft of the motor 3 is fixedly mounted on the short rod 5. The other end of the motor 3 is fixedly mounted in the box body 4. The end of the short rod 5 away from the motor 3 is rotatably connected to the bottom end of the cam 14, and the short rod 5 passes through the box body 4.

[0026] A water inlet check valve is installed in the water inlet pipe 8, and a water outlet check valve is installed in the water outlet pipe 21. It should be noted that the function of the water outlet check valve is that when the piston 18 moves downward, the water outlet check valve opens, and the water outlet pipe 21 draws out the coolant in the piston cylinder 9, and the water inlet check valve is closed at this time. The function of closing the water inlet check valve is that when the piston 18 moves upward, the water outlet check valve closes, the water inlet check valve opens, and the water inlet pipe 8 draws the coolant in the water bucket 15 into the piston cylinder 9 along the water inlet pipe 8.

[0027] There are a number of cleaning leaves 20 on the cleaning plate 11. It should be noted that the cleaning leaves 20 on the cleaning plate 11 are very soft to prevent the surfaces of the heat conducting plate 12 and the heat storage tube 13 from being scratched, but the material of the cleaning leaves 20 is a high temperature resistant material.

[0028] When using the device, the motor 3 is started, and the motor 3 drives the cam 14 to rotate through the short rod 5, and the cam 14 drives the second connecting handle 17 to rotate, and the second connecting handle 17 and the first connecting handle 16 drive the cleaning plate 11 to move repeatedly, at which time the cleaning leaves 20 on the cleaning plate 11 clean the dust on the surface of the heat conducting plate 12 and the heat storage tube 13, and the cleaning plate 11 drives the slider 7 to slide repeatedly in the groove 6. At the same time, the slider 7 drives the guide rod 10 to move, and the guide rod 10 drives the piston 18 to move.

[0029] When the piston 18 moves downward, due to the effect of the one-way valve of the water outlet pipe, the coolant in the piston cylinder 9 can only flow into the water bucket 15 from the water outlet pipe 21. The water outlet pipe 21 is fixed to the bottom of the battery 1, so when the coolant flows through the water outlet pipe 21, the bottom of the battery 1 can be cooled. When the piston 18 moves upward, due to the effect of the one-way valve of the water inlet pipe, the coolant in the water bucket 15 can only flow into the piston cylinder 9 from the water inlet pipe 8, thereby realizing the circulation of the coolant and reducing the temperature of the battery 1.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
