Description

Technical Field

[0001] The present invention relates to the technical field of new energy batteries, and in particular to a new energy battery heat preservation device. Background Art

[0002] New energy batteries are batteries made of new materials, among which commonly used ones include lithium-ion batteries, referred to as lithium batteries. There are many types of lithium batteries, among which portable mobile lithium power supplies are mostly used as mobile power supplies and are often carried outdoors for use. Since lithium power supplies are rechargeable batteries, their positive and negative electrodes are lithium metal or lithium alloy, and non-aqueous electrolyte solution is used as their working medium. Lithium batteries require electrochemical reactions during charging and discharging. At different temperatures, the activity of the electrochemical reactions of charging and discharging inside the battery will change. When the outdoor temperature is low, the performance of the lithium power supply will decrease. For example, when the temperature is below 0°, the discharge capacity of the lithium battery will decrease faster. When the temperature is below minus 20°, the internal resistance of the lithium battery will double, exacerbating the power consumption in the lithium power supply. When the temperature is lower, charging and discharging may even be impossible.

[0003] In the prior art, in the case where a portable lithium power source is required as mentioned above, it is often impossible to insulate the lithium power source. When a solar panel is used to charge the lithium power source or when the lithium power source is needed, the lithium power source often cannot work due to the low temperature. At this time, it can only be insulated by simple methods, such as placing the lithium power source in a relatively closed environment to reduce the heat transfer between the surrounding environment and the outside world. Since the lithium power source will dissipate heat during charging and discharging, the efficiency of the lithium power source's heat dissipation is reduced to a certain extent. Furthermore, cotton clothes and quilts may be placed around the lithium power source to keep it warm, but the effect is minimal and the working efficiency of the lithium power source will still be greatly reduced. Summary of the Invention

[0010] In the above-mentioned new energy battery insulation device, two symmetrical No. 2 heat-conducting blocks are arranged in the insulation inner tank, and the two No. 2 heat-conducting blocks are fixedly installed with extrusion springs on the side away from each other, and the end of the extrusion spring away from the No. 2 heat-conducting block is fixedly installed on the inner wall of the insulation inner tank.

The two sides of the insulation plug-in plate are respectively in conflict with the No. 1 heat-conducting block and the No. 2 heat-conducting block.

[0011] In the above-mentioned new energy battery heat preservation device, a partition groove is opened on the inner wall of the heat dissipation through hole, and a circular heat-insulating circular plate with a circular structure is slidably connected in the partition groove.

[0012] In the above-mentioned new energy battery insulation device, a heat dissipation motor is fixedly installed on the inner wall of the No. 2 fixed tube through a bracket, and heat dissipation blades evenly distributed along its circumference are fixedly installed on the output shaft of the heat dissipation motor.

By placing a removable lithium power source in the insulation inner container and making its outer shell contact the first heat-conducting block, the heat emitted by the lithium power source itself can be transferred to the insulation foam board through the copper sheet. At the same time, when the ambient temperature is very low, a self-heating pack and water can be added to the stuffing box. The heat released by the self-heating pack can be absorbed by the heat-absorbing block to heat the lithium power source, thereby avoiding the performance degradation of the lithium power source due to the low temperature.

[0016] The present invention incorporates a second heat conducting block and a heat dissipation motor. When the ambient temperature is high, the insulation plate can be removed to allow the first and second heat conducting blocks to come into contact, dissipating heat through the heat dissipation copper tube and aluminum fins. This, combined with a cooling fan and heat dissipation blades, cools the lithium power supply, eliminating safety hazards associated with overheating. BRIEF DESCRIPTION OF THE DRAWINGS

The heat emitted by the lithium power supply can be used for insulation. The two No. 1 empty slots 202, the two No. 2 empty slots 203 and the No. 3 empty slot 204 together constitute a vacuum slot, which can reduce heat dissipation. A self-heating bag is placed in the stuffing box 103, and hot steam can be released by adding water to heat the thermal insulation liner 3.

[0031] A fixed tube No. 1 205 with an annular structure is fixedly installed in the empty slot No. 3 204, a heat transfer hole 301 is opened on the inner wall of the thermal insulation liner 3, and a trumpet-shaped gas collecting pipe 9 is fixedly installed on the inner wall of the fixed slot 101. The gas collecting pipe 9 is inserted into the heat transfer hole 301 on the side close to the thermal insulation unit 2. A sealing rubber ring 10 with an annular structure is fixedly installed on the end of the gas collecting pipe 9 close to the heat transfer hole 301. The sealing rubber ring 10 conflicts with the inner wall of the heat transfer hole 301. A heat absorbing block 11 with a cylindrical structure is fixedly installed in the heat transfer hole 301. The heat absorbing block 11 is used to absorb and transfer the heat emitted from the filling slot 102 to the thermal insulation liner 3. The gas collecting pipe 9 is used to gather water vapor to improve the utilization rate of water vapor thermal energy.

[0032] A number of heat transfer copper tubes 1101 evenly distributed along the circumference are fixedly installed on the outer coin of the heat absorption block 11, and a heating foam plate 12 is arranged in the temperature tank. A heat block pasting groove 1201 is provided at the bottom of the heating foam plate 12, and a number of evenly distributed heat pipe slots 1202 are provided on the inner wall of the heat block pasting groove 1201. The bottom of the heat pipe slot 1202 passes through the lower surface of the heating foam plate 12. The heat pipe slots 1202 correspond one-to-one to the heat transfer copper tubes 1101. There are ten heat transfer copper tubes 1101, and the ten heat transfer copper tubes 1101 are symmetrical in 50-50. The heat transfer copper tubes 1101 are used to evenly disperse the heat on the heat absorption block 11, and transfer the heat to the heating foam plate 12 through the heat transfer copper tubes 1101, so as to prevent the heat absorption block 11 from being overheated and causing damage to the outer shell of the mobile lithium power supply.

[0033] Two symmetrical No. 2 heat-conducting blocks 13 are arranged in the heat-insulating liner 3. The two No. 2 heat-conducting blocks 13 are fixedly installed with an extrusion spring 14 on the side away from each other. The end of the extrusion spring 14 away from the No. 2 heat-conducting block 13 is fixedly installed on the inner wall of the heat-insulating liner 3. The No. 2 heat-conducting block 13 corresponds to the No. 1 heat-conducting block 4 one by one. A heat-insulating plug-in plate 15 is arranged between the No. 2 heat-conducting block 13 and the No. 1 heat-conducting block 4. The two sides of the heat-insulating plug-in plate 15 are respectively in conflict with the No. 1 heat-conducting block 4 and the No. 2 heat-conducting block 13. Two No. 2 fixed tubes 206 with symmetrically arranged annular structures are fixedly installed on the inner wall of the No. 2 empty slot 203. Two symmetrically arranged heat dissipation through-holes 302 are provided on the inner wall of the heat-insulating liner 3. The thermal through hole 302 corresponds to the No. 2 thermal conductive block 13 one by one. The end of the heat dissipation through hole 302 away from the corresponding No. 2 thermal conductive block 13 passes through the side of the thermal insulation unit 2. Four extrusion springs 14 are provided, which are respectively located at the four corners of the No. 2 thermal conductive block 13 to increase its stability. The length of the No. 2 thermal conductive block 13 is greater than the diameter of the heat dissipation through hole 302 and less than the length of the No. 1 thermal conductive block 4. The thermal insulation plug-in plate 15 is detachable. When the thermal insulation plug-in plate 15 is inserted, the No. 1 thermal conductive block 4 does not contact the No. 2 thermal conductive block 13, thereby avoiding heat loss when the lithium power supply is moved. When the thermal insulation plug-in plate 15 is removed, the No. 1 thermal conductive block 4 contacts the No. 2 thermal conductive block 13, and the heat of the lithium power supply can be dissipated through the heat dissipation through hole 302.

[0034] A partition groove 303 is provided on the inner wall of the heat dissipation hole 302, and a circular insulation circular plate 304 is slidably connected in the partition groove 303. A pull rod is slidably connected to the bottom of the insulation circular plate 304. When the lithium power supply is kept warm, the insulation circular plate 304 can prevent the heat of the lithium power supply from dissipating through the heat dissipation hole 302.

[0035] A heat dissipation motor 16 is fixedly mounted on the inner wall of the second fixed tube 206 through a bracket, and heat dissipation blades 17 evenly distributed along its circumference are fixedly mounted on the output shaft of the heat dissipation motor 16. When the temperature of the lithium power supply is too high, the heat dissipation blades 17 can be started to rotate to cool the lithium power supply.

[0036] A pressure limiting valve 18 is fixedly installed on the inner wall of the fixed groove 101 and located in the gas gathering pipe 9. A through hole is opened on the inner wall of the gas gathering pipe 9. Condensation through holes 901 are opened on the inner wall of the gas gathering pipe 9 and are evenly distributed along its circumference. A number of condensing pipes 19 evenly distributed along its outer wall are fixedly installed on the outer wall of the gathering pipe. The condensing pipes 19 correspond one-to-one to the condensing through holes 901. A number of evenly distributed ventilation holes 105 are opened on the inner wall of the fixed groove 101. When the water vapor in the filling groove 102 reaches a certain pressure, the water vapor is discharged through the pressure limiting valve 18, thereby increasing the pressure of the water vapor ejected and improving the heating efficiency of the heat absorption block 11. The condensing pipe 19 is used to liquefy the water vapor to prevent the water vapor pressure from being too high and lifting the insulation unit 2.

[0037] A number of evenly distributed U-shaped heat dissipation copper tubes 20 are fixedly installed on the side of the No. 2 heat-conducting block 13 away from the No. 1 heat-conducting block 4. A number of evenly distributed heat dissipation aluminum fins 21 are arranged in the heat dissipation through-holes 302. The heat dissipation copper tubes 20 all penetrate the heat dissipation aluminum fins 21 and are fixedly connected to the heat dissipation aluminum fins 21. The heat dissipation copper tubes 20 cooperate with the heat dissipation aluminum fins 21 to improve the heat dissipation efficiency.

[0038] The specific working principle and method of use of the present invention are explained in detail below: During use, when the temperature of the lithium power supply is low, the lithium power supply can be placed in the thermal insulation inner liner 3. At this time, the thermal insulation plug-in plate 15 is inserted into the No. 1 thermal conductive block 4 and the No. 2 thermal conductive block 4. The thermal insulation plug-in plate 15 can isolate the heat transfer between the No. 1 thermal conductive block 4 and the No. 2 thermal conductive block 13 to a certain extent. Then, the thermal insulation circular plate 304 is pulled down to reduce heat loss. At this time, the heat emitted by the lithium power supply itself during operation will be transferred to the copper sheet 5 through the No. 1 thermal conductive block 4, and then transferred to the thermal insulation foam board 6 through the copper sheet 5. Then, the thermal insulation cover 8 is covered to achieve the effect of heat preservation of the lithium power supply.

[0039] When the ambient temperature is too low and the lithium power supply cannot rely on the heat emitted by itself to keep warm, the insulation unit 2 can be placed in the fixed groove 101. At this time, the bracket at the bottom of the insulation unit 2 will hold up the insulation unit 2 so that the bottom of the insulation unit 2 is at a certain distance from the fixed groove 101. At this time, the self-heating bag can be placed in the stuffing box 103 and water is added. At this time, the self-heating bag will heat the water and generate high-temperature water vapor. When the pressure of the water vapor in the stuffing groove 102 reaches a certain threshold, the water vapor will lift the pressure limiting valve 18 and spray to the bottom of the heat absorption block 11 through the gas collecting pipe 9. At this time, the bottom of the heat absorption block 11 will be heated and the heat will be transferred to the heat transfer copper tube 1101. The heat transfer copper tube 1101 cooperates with the heat absorption block 11 to disperse the heat to the heating foam board 12, and cooperates with the insulation unit 2 to heat the lithium power supply.

[0040] After the water vapor transfers heat to the heat absorbing block 11, it will condense into water through the condenser tube 19 and flow out of the gas collecting tube 9. The ventilation hole 105 makes the fixed tank 101 connected to the outside world, which can improve the condensation effect of the water vapor. The condensed water will remain in the fixed tank 101.

[0041] When the ambient temperature is high or the internal temperature of the lithium power supply is high due to a heavy load, the thermal insulation cover 8 is removed, the thermal insulation unit 2 is removed from the fixing groove 101, and the thermal insulation plug plate 15 is pulled out, so that the No. 1 thermal conductive block 4 and the No. 2 thermal conductive block 13 are in contact with each other. The heat on the lithium power supply is transferred to the heat dissipation copper tube 20 through the No. 1 thermal conductive block 4 and the No. 2 thermal conductive block 13, and then further transferred to the heat dissipation aluminum sheet 21. At the same time, the thermal insulation circular plate 304 is placed in the partition groove 303. At this time, the heat dissipation motor 16 can be started, and the heat is taken away by the airflow under the action of the heat dissipation blades 17, which can cool the lithium power supply to a certain extent.

[0042] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
