This embodiment discloses a novel battery cooling structure based on heat pipe and liquid cooling plate coupling mainly includes: the liquid cooling device comprises a battery 7, a liquid cooling plate 5 and an L-shaped heat pipe 2, wherein the battery 7 is a single battery, is of a cuboid structure and is arranged vertically; the liquid cooling plate 5 is an aluminum alloy part, is of a plate-shaped structure, is arranged below the battery 7, and is welded and fixed on a bottom plate of the battery device; the L-shaped heat pipe 2 is a copper component and comprises a vertical evaporation section 4 and a horizontal condensation section 3, wherein the evaporation section 4 is attached to the wall surface of the battery 7, and the condensation section 3 is attached to the liquid cooling plate 5.
Preferably, the upper copper plate 1 is arranged between the wall surface of the battery 7 and the evaporation section 4, the lower copper plate 6 is arranged between the liquid cooling plate 5 and the condensation section 3, and straight line sections of the upper copper plate 1 and the lower copper plate 6 are perpendicular to each other.
The heat-conducting silicone grease is uniformly filled between the upper copper plate 1 and the wall surface of the battery 7 and between the lower copper plate 6 and the liquid cooling plate 5, so that the heat dissipation effect is more uniform and efficient. Go up the top of copper 1 and link to each other with battery 7 wall top, go up the bottom of copper 1 and the bottom of battery 7 wall and set up the headspace, this headspace sets up highly to 4 +/-1 mm, preferred setting up to 4mm, and specific highly is according to the nimble setting of specification of battery 7, liquid cooling plate 5 and battery assembly. The lower copper plate 6 has one end connected to the bottom of the wall of the battery 7 and the other end connected to the edge of the liquid-cooled plate 5.
The upper edge of the upper copper plate 1 is connected with the end part of the evaporation section 4 of the L-shaped heat pipe 2, and the outer edge of the lower copper plate 6 is connected with the end part of the condensation section 3 in a sealing and welding mode, and the integrated structure is formed. The integrated structure is symmetrically arranged about the battery 7, namely the battery 7 is positioned at the center of the liquid cooling plate 5, and the integrated structure is symmetrically arranged at two sides of the battery 7 respectively.
Preferably, in this embodiment, the L-shaped heat pipe 2 includes a copper casing, a wick and a heat transfer medium, both the wick and the heat transfer medium are disposed in the copper casing, and in this embodiment, the heat transfer medium is a liquid-phase working medium, which may be water. The L-shaped heat pipe 2 is a copper water sintered heat pipe, the size range of the L-shaped heat pipe is that the diameter of the initial heat pipe is 6 +/-1 mm, the L-shaped heat pipe is pressed into a flat pipe body with the width of 8 +/-1 mm and the thickness of 3 +/-1 mm, and the L-shaped heat pipe is further bent to be in an L shape. Preferably, the initial heat pipes 2 are each set to have a diameter of 6mm, and then pressed into a flat pipe body having a width of 8mm and a thickness of 3 mm. Two sides of the battery 7 are respectively provided with 4L-shaped heat pipes 2. The evaporation section 4 and the condensation section 3 of the L-shaped heat pipe 2 are smoothly transited.
Lithium ion power battery can produce a large amount of heats at its wall and bottom when normal work, because the existence of liquid cold plate 5, the heat transfer effect of battery 7 bottom is better usually, and battery main body wall leads to its surface temperature's uniformity to worsen owing to there is not comparatively ideal cooling measure, and battery 7's overall heat transfer effect reduces. In the embodiment, the heat of the wall surface of the battery main body is uniformly transferred to the evaporation section 4 of the L-shaped heat pipe 2 through the upper copper plate 1, and the working medium of the evaporation section 4 evaporates and absorbs the heat and flows downwards under the driving of the temperature difference. Condensation segment 3 and lower copper 6 zonulae occludens, and the temperature is lower relatively, and the working medium that flows downwards contracts into the imbibition core again after meeting cold liquefaction release heat and flows upwards, and the heat that releases passes to liquid cooling board 5 via lower copper 6 again, is taken away by the working medium in the liquid cooling board 5, makes battery 7's cooling effect obtain improving, has improved the homogeneity of battery 7 temperature to make battery 7's performance obtain improving.
Fig. 3 and 4 show experimental studies on the heat dissipation performance of the battery 7 under the charge-discharge cycle conditions in which the battery is continuously operated under severe conditions. The severe regime refers to the ambient temperature and coolant being maintained at 35 ℃ with a low flow rate of 0.5L/min coolant. In the experimental process, the battery 7 is discharged at a rate of 2C, is placed for 1 minute and then is charged at a rate of 1C, is placed for 1 minute after the charging is finished and then is discharged at a rate of 2C, and then is discharged for 3 times. The experiment also contrasts the cooling performance of referring to two cooling modes of air cooling and liquid cooling.
Referring to fig. 3, when air cooling is applied to the battery 7, the temperature of the battery 7 is higher than 40 ℃ and can reach 46.2 ℃ at most at all times except for the first discharge and charge cycle, which is far beyond the optimal operating temperature range of the battery 7 (NC curve in the figure). When the battery 7 is cooled by the liquid cooling method, the wall temperature of the battery 7 is reduced as a whole compared with that of the air cooling unit, but the temperature exceeds the upper limit of the optimal operation temperature range (LC curve in the figure) of the battery 7 at 40 ℃ in the later discharge period and the early charge period. Therefore, the cooling requirements of the battery 7 under severe conditions cannot be met by the two cooling modes of air cooling and liquid cooling. When the heat pipe and liquid cooling plate coupling structure of the embodiment is adopted to cool the battery, the wall surface temperature is only 38.6 ℃ at most, the battery temperature is effectively controlled and is always in the optimal operation temperature range (LC-HP curve in the figure).
Referring to fig. 4, the temperature difference fluctuation of the wall surface of the battery 7 is shown under different cooling modes in the circulation process. The highest temperature difference can reach 3 ℃ under the liquid cooling condition, which is mainly because the liquid cooling only cools the bottom of the battery 7 and the wall surface of the battery 7 is not effectively cooled. When air cooling is adopted, the uniformity of the temperature of the battery 7 is better, and the reason is that the cooling effect of the air cooling is poorer, and the overall temperature of the battery 7 is higher and the temperature difference is smaller. The novel heat pipe and liquid cooling plate coupling structure has the best cooling effect, the wall surface temperature of the battery 7 is more uniform compared with air cooling and liquid cooling, and the maximum temperature difference is only 1 ℃. This is related to the good heat dispersion of heat pipe 2/liquid cooling board 5 structure, on the basis that liquid cooling carries out effective cooling to battery 7 bottom, utilizes copper, heat pipe etc. to increase the heat dissipation of battery 7 wall for battery 7 wall difference in temperature further reduces, therefore total cooling effect obtains certain promotion compared with traditional cooling method.
In the previous description, numerous specific details were set forth in order to provide a thorough understanding of the present invention. The foregoing description is only a preferred embodiment of the invention, which can be embodied in many different forms than described herein, and therefore the invention is not limited to the specific embodiments disclosed above. And that those skilled in the art will be able to make many changes and modifications to the invention using the method and techniques disclosed above, or to modify and adapt equivalent embodiments to equivalent variations, without departing from the scope of the invention.
