The vehicle air conditioner 61 includes a heat exchange duct that outputs heated or cooled air, and the heat exchange duct communicates to the heat exchange box 62 through the heat exchange line 63. For ease of observation, the vehicle body 1 of the electric vehicle is simplified to a chassis structure in FIG.
本实施中的电动汽车控温系统在电池组12外加装了热交换箱62，热媒621包裹于电池组12的外侧，通过车载空调61对热交换箱62进行温控，从而达到对电池组12进行温控的目的。现有技术中的车载空调61均具有加热和制冷的作用，可以将空气加热或降温后输出，能对电池组12降温，还能在低温时对电池组12进行加热，使其电池组12能长期处于适宜的工作温度范围。而降温方式为利用包在电池组12外的热交换箱62内部的热媒进行热交换，而非现有技术中的直接风冷，对成排的电池组12也能无死角进行热交换，散热效果好，能耗低，不会影响电动汽车的行驶距离。The electric vehicle temperature control system in the present embodiment is provided with a heat exchange box 62 outside the battery pack 12, and the heat medium 621 is wrapped around the outside of the battery pack 12, and the heat exchange box 62 is temperature-controlled by the vehicle air conditioner 61 to achieve the battery. Group 12 performs the purpose of temperature control. The vehicle air conditioner 61 in the prior art has the functions of heating and cooling, can output air after heating or cooling, can cool the battery pack 12, and can heat the battery pack 12 at a low temperature to enable the battery pack 12 to Long-term in the appropriate operating temperature range. The cooling method is to exchange heat with the heat medium inside the heat exchange box 62 outside the battery pack 12, instead of the direct air cooling in the prior art, and the row of battery packs 12 can also exchange heat without dead angles. The heat dissipation effect is good, the energy consumption is low, and the driving distance of the electric vehicle is not affected.
由于大部分电动汽车都具有车载空调61，所以本实施例中的电动汽车控温系统可以通过在现有技术中的电动汽车中加装热交换箱62，并对车载空调61输出管路进行改装即可，其改装成本低，适用范围广。Since most of the electric vehicles have the vehicle air conditioner 61, the electric vehicle temperature control system in this embodiment can be retrofitted with the heat exchange box 62 in the electric vehicle of the prior art, and the output pipeline of the vehicle air conditioner 61 can be modified. It can be used, its conversion cost is low, and its application range is wide.
本实施中的热交换管路63排布结构如图3所示，包括多个连接管路632和大梁管路631，大梁管路631环绕铺设于车体1，相当于“主干道”，连接管路632将大梁管路631连通至车载空调61、热交换箱62，相当于“支路”。在热交换管路63节点处设有多向伺服阀633，可以分配经过的各管路的流量，保证车内有合适的风量，热交换箱62有足量的空气进行热交换。As shown in FIG. 3, the arrangement structure of the heat exchange line 63 in the present embodiment includes a plurality of connecting lines 632 and a beam line 631. The beam line 631 is laid around the vehicle body 1, which is equivalent to the "main road" and is connected. The line 632 connects the beam line 631 to the vehicle air conditioner 61 and the heat exchange box 62, which is equivalent to a "branch". A multi-directional servo valve 633 is provided at the junction of the heat exchange line 63, and the flow rate of each passing pipe can be distributed to ensure a proper air volume in the vehicle, and the heat exchange box 62 has a sufficient amount of air for heat exchange.
电池组12包括电芯、支撑板以及连接管，电芯分层设置于多层的支承板上，支承板内设有热交换流道，连接管将各层支承板内部的热交换流道连通至热交换箱62，使电池组12内部也能进行热交换，将内部的热量交换至热交换箱62，然后再交换至车载空调61，进一步加强了热交换效率，间接减少了控温消耗的功率，而且避免在电池组12内部出现控温死角，延长了电池组12的使用寿命。The battery pack 12 includes a battery core, a support plate and a connecting tube. The battery core is layered on the support plate of the plurality of layers. The support plate is provided with a heat exchange flow channel, and the connecting pipe connects the heat exchange flow passages inside the support plates of the respective layers. To the heat exchange box 62, heat exchange can also be performed inside the battery pack 12, the internal heat is exchanged to the heat exchange box 62, and then exchanged to the vehicle air conditioner 61, thereby further enhancing the heat exchange efficiency and indirectly reducing the temperature control consumption. Power, and avoiding the occurrence of temperature-controlled dead angle inside the battery pack 12, prolongs the service life of the battery pack 12.
如图2和图3所示，热交换管路63上设有多个出风口6321，出风口6321位于连接管路632上，并伸入车内，为车内提供加温或者降温。As shown in FIG. 2 and FIG. 3, the heat exchange line 63 is provided with a plurality of air outlets 6321. The air outlets 6321 are located on the connecting pipelines 632 and extend into the vehicle to provide heating or cooling for the interior of the vehicle.
电池组12外设有隔水层，热媒621为灌注在热交换箱62空腔内的水，所述热交换管路的一部分，即图2中的连接管路632部分，盘设于空腔内，并浸于水中，与热交换箱62进行热交换。水是一种常见的热媒，其比热容较高，流动性好，不仅容易进行热交换，而且不易被改变温度，便于使电池组12处于一个温度范围。 The water pack 12 is provided with a water-repellent layer outside, and the heat medium 621 is water poured into the cavity of the heat exchange box 62. A part of the heat exchange line, that is, a part of the connecting line 632 in FIG. 2, is disposed in the air. The chamber is immersed in water and exchanges heat with the heat exchange box 62. Water is a common heat medium, which has higher specific heat capacity and good fluidity. It is not only easy to exchange heat, but also difficult to change temperature, so that the battery pack 12 is in a temperature range.
车载空调61包括相互连通的电动压缩机、冷凝器611、冷凝罐、蒸发器614和电子风扇613，冷凝器611和蒸发器614即为空调中制热和制冷的部件，这两个部分连接至热交换风管，与外界进行热交换。The vehicle air conditioner 61 includes an electric compressor that communicates with each other, a condenser 611, a condensation tank, an evaporator 614, and an electronic fan 613. The condenser 611 and the evaporator 614 are components for heating and cooling in the air conditioner, and the two parts are connected to Heat exchange ducts for heat exchange with the outside world.
冷凝器611外设有双层的壳体，外层的壳体通过两根连接杆固定于电动汽车车体1。冷凝器611通过额外设置的壳体固定于车体1，即能保证固定稳固，又加大了冷凝器611与车体1的距离，使其不易受到车体1温度的影响，从而降低功耗，这部分结构为现有技术的灵活应用，未在图中示出。A condenser is provided outside the condenser 611, and the outer casing is fixed to the electric vehicle body 1 by two connecting rods. The condenser 611 is fixed to the vehicle body 1 through an additionally provided casing, that is, the fixing and securing can be ensured, and the distance between the condenser 611 and the vehicle body 1 is increased, so that the temperature of the vehicle body 1 is not easily affected, thereby reducing power consumption. This part of the structure is a flexible application of the prior art and is not shown in the figure.
如图1所示，车载空调61位于车体1后部。蒸发器614设于车体1下端，电子风扇613设于蒸发器614一侧，且电子风扇613送风方向为自车体1内向外吹向蒸发器614，即向车体1的后面输出空气，既能起到促进蒸发器614冷却的作用，又带走了车体1内的热空气，降低了其内部温度。如果将上述结构设置于车体1的前端，吹出的热空气不仅无法带走车体1内的温度，而且会在行驶中会进入车体1，增加其内部的温度，影响各部件工作。As shown in FIG. 1, the vehicle air conditioner 61 is located at the rear of the vehicle body 1. The evaporator 614 is disposed at the lower end of the vehicle body 1, and the electronic fan 613 is disposed at the side of the evaporator 614, and the air blowing direction of the electronic fan 613 is blown from the inside of the vehicle body 1 to the evaporator 614, that is, the air is output to the rear of the vehicle body 1. The utility model can not only promote the cooling of the evaporator 614, but also remove the hot air in the vehicle body 1 and reduce the internal temperature thereof. If the above structure is provided at the front end of the vehicle body 1, the blown hot air can not only take away the temperature inside the vehicle body 1, but also enter the vehicle body 1 during traveling, increasing the temperature inside thereof and affecting the operation of each component.
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention.
