A heat pipe 3 is sandwiched between two adjacent battery cells. The outermost battery cell in the battery pack in the thickness direction Heat pipes 3 are also arranged on the body surface; the heat pipes in each battery pack extend to the direction where the other battery pack is located to form a heat pipe condensation section 31, and two up and down opposite heat pipe condensation sections 31 are arranged in close contact with each other from top to bottom. Composite phase-change material plate 4, heat dissipation frame 5 and composite phase-change material plate 6 are arranged; described heat dissipation frame 5 comprises two heat dissipation patches 51 arranged oppositely and a plurality of fins 52 for connecting two heat dissipation patches, two The heat dissipation patch 51 is attached to the corresponding composite phase-change material plate 6; an air duct 7 perpendicular to the length direction of the heat pipe is formed between two adjacent fins 52, and a heat dissipation device is provided on the side wall of the battery box. A fan 8, the cooling fan 8 faces the air duct 7. In this embodiment, the battery cells 11 are square lithium-ion power batteries, the battery cells of the battery pack can be connected in series and parallel, and the structure of double battery packs symmetrically arranged can be used without affecting the heat dissipation performance. Better increase the space utilization rate, improve the thermal uniformity of each battery module of the battery pack at the same time, and improve the power performance and service life of the battery.
具体的，所述电池箱体内还设置有温度传感器和控制器（图中未画出），所述温度传感器与控制器连接，其温度探头设置在电池单体上，所述散热风扇与控制器电连接。本实施例中，所述控制器设置为单片机，设置于电池箱体底部，温度传感器将探测的温度信息传输给单片机，单片机通过编写的程序对温度信息进行处理，如果电池单体的温度高于设定值，单片机控制散热风扇转动；若电池单体的温度在低于设定值，则散热风扇不工作。通过这样设置，可以使电池的温度维持在最佳的工作温度范围内，同时还能节省效能。Specifically, the battery box is also provided with a temperature sensor and a controller (not shown in the figure), the temperature sensor is connected to the controller, and its temperature probe is set on the battery cell, and the cooling fan is connected to the controller electrical connection. In this embodiment, the controller is set as a single-chip microcomputer, which is arranged at the bottom of the battery box, and the temperature sensor transmits the detected temperature information to the single-chip microcomputer, and the single-chip microcomputer processes the temperature information through the written program. If the temperature of the battery cell is higher than The set value, the microcontroller controls the cooling fan to rotate; if the temperature of the battery cell is lower than the set value, the cooling fan does not work. By setting in this way, the temperature of the battery can be maintained within the optimum operating temperature range, and at the same time energy can be saved.
当电池组进行充放电时，每个电池单体11产生大量的电化学反应热和焦耳热，使电池表面温度逐渐升高。首先将产生的大量热量传递到与电池单体两侧面相接触的热管3上，然后再通过热管冷凝段31传递给复合相变材料板6。如果这时温度已经超过复合相变材料板的熔点温度，则相变材料开始发生相位变化，通过固态变为液态相变吸收大量潜热，从而很好地减缓电池组温度的上升，避免其过热。并且如果电池组1处于高放电倍率、高工作温度的特殊工况下，仅仅依靠相变材料的相位变化吸热已经无法满足电池组冷却的要求，此时温度传感器探测到电池单体的温度超过设定温度时，控制散热风扇进行风冷，减低电池箱体内的环境温度，起到散热效果。较佳的是，散热风扇会使风道形成气流，让气流带走散热贴片51和鳍片52上的热量，加速对复合相变材料板的散热，从而增长复合相变材料板的使用寿命，整体提高电池组的安全性和使用寿命。When the battery pack is being charged and discharged, each battery cell 11 generates a large amount of electrochemical reaction heat and Joule heat, which gradually increases the surface temperature of the battery. Firstly, a large amount of heat is transferred to the heat pipe 3 in contact with the two sides of the battery cell, and then transferred to the composite phase-change material plate 6 through the condensation section 31 of the heat pipe. If the temperature has exceeded the melting point of the composite phase-change material plate at this time, the phase-change material will begin to undergo a phase change, and absorb a large amount of latent heat through the solid-to-liquid phase transition, thereby well slowing down the temperature rise of the battery pack and avoiding its overheating. And if the battery pack 1 is in a special working condition of high discharge rate and high working temperature, relying only on the phase change heat absorption of the phase change material can no longer meet the cooling requirements of the battery pack. At this time, the temperature sensor detects that the temperature of the battery cell exceeds When setting the temperature, control the cooling fan for air cooling, reduce the ambient temperature in the battery box, and play a cooling effect. Preferably, the heat dissipation fan will form the air duct to form an airflow, allowing the airflow to take away the heat on the heat dissipation patch 51 and the fins 52, so as to accelerate the heat dissipation of the composite phase change material plate, thereby increasing the service life of the composite phase change material plate , Improve the safety and service life of the battery pack as a whole.

优选的，所述复合相变材料板6包括石蜡、石墨烯粉末、聚氨酯软泡沫铜材质。复合相变材料板制造过程是石蜡在熔融后的液态状态下加入石墨烯粉末均匀混合，而后加压填充至聚氨酯软泡沫铜内，待冷却凝固后对样件上下表面进行校平，最后制成复合相变材料板。需要说明的是，石墨烯粉末是一种由碳原子以sp²杂化轨道组成六角型呈蜂巢晶格的二维碳纳米材料，具有优良的导热性能，将其与石蜡结合在一起可以很好的弥补石蜡热导率的不足。Preferably, the composite phase-change material plate 6 is made of paraffin wax, graphene powder, and polyurethane soft foam copper. The manufacturing process of the composite phase change material board is that the paraffin wax is added to the molten liquid state and graphene powder is evenly mixed, and then pressurized and filled into the polyurethane soft foam copper. After cooling and solidifying, the upper and lower surfaces of the sample are leveled, and finally made Composite phase change material panels. It should be noted that graphene powder is a two-dimensional carbon nanomaterial composed of carbon atoms in sp ² hybridized orbitals to form a hexagonal honeycomb lattice.
