如图1-图3所示,本实施例提供一种风冷电池箱,该风冷电池箱包括底板100和壳体300。其中,底板100上设置有进风口110和出风口120,底板100内部设置有若干条流道130,流道130将进风口110和出风口120连通。可选地,本实施例中的流道130可以设置为1条、2条、3条、4条等其他数量,此处不再一一赘述。底板100上设置有电池模组200,底板100朝向电池模组200的一侧开设有若干第一通风孔140,第一通风孔140连通于流道130;进风口110和出风口120之间连通有空调组件(图中未示出),空调组件被配置为调节风温和风速。壳体300盖合在底板100上以形成容置空腔,电池模组200置于容置空腔中。As shown in FIGS. 1-3 , this embodiment provides an air-cooled battery box, which includes a bottom plate 100 and a casing 300 . Wherein, the bottom plate 100 is provided with an air inlet 110 and an air outlet 120 , and inside the bottom plate 100 is provided with several flow channels 130 , and the flow channels 130 connect the air inlet 110 and the air outlet 120 . Optionally, the number of flow channels 130 in this embodiment can be set to 1, 2, 3, 4, etc., which will not be repeated here. The bottom plate 100 is provided with a battery module 200, and the side of the bottom plate 100 facing the battery module 200 is provided with a plurality of first ventilation holes 140, the first ventilation holes 140 are connected to the flow channel 130; the air inlet 110 and the air outlet 120 are connected There is an air conditioning unit (not shown in the figure), which is configured to adjust the wind temperature and wind speed. The casing 300 is covered on the bottom plate 100 to form a receiving cavity, and the battery module 200 is placed in the receiving cavity.

进一步地,如图1所示,壳体300上开设有若干个第二通风孔310,第二通风孔310的设置有利于风流能够沿着第一通风孔140流向至容置空腔,再由容置空腔流向第二通风孔310,使得风能够将电池模组200中的热量由第二通风孔310带出。Further, as shown in FIG. 1 , several second ventilation holes 310 are opened on the housing 300 . The arrangement of the second ventilation holes 310 facilitates the flow of wind to the accommodation cavity along the first ventilation holes 140 , and then the The accommodating cavity flows to the second ventilation hole 310 , so that the wind can take the heat in the battery module 200 out through the second ventilation hole 310 .

基于以上设计,该风冷电池箱工作时,空调组件沿进风口110将一定风温和一定风速的风吹进底板100内,然后风沿着底板100内的流道130进行流动,在风流动的过程中,一部分风量能够沿着第一通风孔140流向出,并流向电池模组200内对电池模组200进行散热降温,然后携带电池模组200的热量的风能够经过第二通风孔310流出;另一部分风量能够继续沿着流道130进行流动,最终由出风口120流出,并流向空调组件,实现循环。作业人员能够根据电池模组200的实际温度来调节空调组件的风速和风温,进而便于实现对电池模组200的有效热管理,延长电池模组200的使用寿命。示例性地,车辆驾驶室内部设置有温度显示仪表,用于对电池模组200的温度进行实时检测并显示,驾驶室内部还设置有空调组件的调温旋钮和调风速旋钮,作业人员能够根据温度显示仪表显示的电池模组200的温度,对调温旋钮和调风速旋钮进行调节,进而实现对电池模组200的有效热管理。Based on the above design, when the air-cooled battery box is in operation, the air-conditioning assembly blows wind of a certain temperature and speed into the bottom plate 100 along the air inlet 110, and then the wind flows along the flow channel 130 in the bottom plate 100. During the process, a part of the air volume can flow out along the first ventilation hole 140 , and flow into the battery module 200 to dissipate heat and cool down the battery module 200 , and then the wind carrying the heat of the battery module 200 can flow out through the second ventilation hole 310 The other part of the air volume can continue to flow along the flow channel 130, and finally flow out from the air outlet 120, and flow to the air conditioning component to realize circulation. The operator can adjust the wind speed and wind temperature of the air conditioner assembly according to the actual temperature of the battery module 200 , thereby facilitating effective thermal management of the battery module 200 and prolonging the service life of the battery module 200 . Exemplarily, a temperature display instrument is set inside the cab of the vehicle for real-time detection and display of the temperature of the battery module 200. There are also temperature adjustment knobs and wind speed adjustment knobs for the air conditioning unit inside the cab. The temperature of the battery module 200 displayed by the temperature display instrument is used to adjust the temperature adjustment knob and the wind speed adjustment knob, thereby realizing effective thermal management of the battery module 200 .

与现有技术相比,本实施例提供的风冷电池箱结构简单,制造成本低。通过在底板100上设置若干条流道130和若干个第一通风孔140,使得流向底板100的风能够直接流入电池模组200内部,进而实现对电池模组200的降温散热。该风冷电池箱不需要额外配置风扇等部件,体积小型化,便于加工制造,节约成本;也不存在传统技术中采用液冷模式导致的漏液等危险现象。同时,作业人员能够通过灵活地调节空调组件的风温和风速,进而实现对电池模组200的有效热管理,延长电池模组200的使用寿命。Compared with the prior art, the air-cooled battery box provided by this embodiment has a simple structure and low manufacturing cost. By setting several flow channels 130 and several first ventilation holes 140 on the bottom plate 100 , the wind flowing toward the bottom plate 100 can directly flow into the inside of the battery module 200 , thereby realizing cooling and heat dissipation of the battery module 200 . The air-cooled battery box does not require additional components such as fans, and is small in size, easy to process and manufacture, and saves costs; there is no dangerous phenomenon such as liquid leakage caused by the liquid cooling mode in the traditional technology. At the same time, the operator can flexibly adjust the wind temperature and wind speed of the air-conditioning components, thereby realizing effective thermal management of the battery module 200 and prolonging the service life of the battery module 200 .

如图3所示,在本实施例中,底板100内设置有若干第一隔板150和若干第二隔板160,第一隔板150将相邻两条流道130隔开,第二隔板160的一端抵接在底板100的内壁上,第二隔板160将相邻两条流道130隔开,第二隔板160平行于第一隔板150。As shown in Figure 3, in this embodiment, several first partitions 150 and several second partitions 160 are arranged in the bottom plate 100, the first partitions 150 separate the adjacent two flow passages 130, and the second partitions One end of the plate 160 abuts against the inner wall of the bottom plate 100 , the second partition 160 separates two adjacent flow channels 130 , and the second partition 160 is parallel to the first partition 150 .

示例性地,如图3所示,本实施例中的一个第二隔板160和两个第一隔板150形成一个流道单元,也就是说,每一个流道单元由三条流道130组成,多个流道单元串联连通。这样使得经过进风口110流进底板100中的风流首先沿着第一个流道单元进行流动,然后流经下一个流道单元,最终由出风口120流出。第二隔板160的设置能够将每一个流道单元隔开。当然,作业人员能够根据实际情况,设置不同数量的第一隔板150和不同数量的第二隔板160,进而形成不同数量的流道单元,即本实施例中的流道单元不局限于三条流道130,即流道单元可以由2条、4条、5条、6条等数量的流道130组成,本实施例对此不作限定。Exemplarily, as shown in FIG. 3 , one second partition 160 and two first partitions 150 in this embodiment form a flow channel unit, that is, each flow channel unit is composed of three flow channels 130 , multiple channel units are connected in series. In this way, the wind flowing into the bottom plate 100 through the air inlet 110 first flows along the first channel unit, then flows through the next channel unit, and finally flows out through the air outlet 120 . The arrangement of the second partition 160 can separate each channel unit. Of course, operators can set different numbers of first partitions 150 and different numbers of second partitions 160 according to actual conditions, thereby forming different numbers of flow channel units, that is, the flow channel units in this embodiment are not limited to three. The flow channel 130, that is, the flow channel unit may be composed of 2, 4, 5, 6 or other number of flow channels 130, which is not limited in this embodiment.

如图1所示,在本实施例中,底板100上设置有导热胶400,电池模组200通过导热胶400与底板100连接。导热胶400的设置不仅能够实现电池模组200和底板100的连接,同时也有利于底板100直接与电池模组200进行传热,从而进一步地提高底板100对电池模组200的散热降温效果,延长电池模组200的使用寿命。As shown in FIG. 1 , in this embodiment, a thermally conductive adhesive 400 is disposed on the base plate 100 , and the battery module 200 is connected to the base plate 100 through the thermally conductive adhesive 400 . The arrangement of the thermally conductive adhesive 400 can not only realize the connection between the battery module 200 and the bottom plate 100, but also facilitate the direct heat transfer between the bottom plate 100 and the battery module 200, thereby further improving the cooling effect of the bottom plate 100 on the battery module 200, The service life of the battery module 200 is extended.

如图2所示,在本实施例中,第一通风孔140关于底板100的中心位置呈阵列分布。这样有利于增加风流向电池模组200的面积,提高对电池模组200的散热降温效果,避免出现电池模组200热量集中以及散热死区的现象。第一通风孔140可以设置为圆形孔、条形孔、方形孔等形状,本实施例对此不作限定。As shown in FIG. 2 , in this embodiment, the first ventilation holes 140 are distributed in an array with respect to the central position of the bottom plate 100 . This is beneficial to increase the area where the wind flows to the battery module 200 , improve the heat dissipation and cooling effect on the battery module 200 , and avoid the phenomenon of heat concentration and heat dissipation dead zone of the battery module 200 . The first ventilation hole 140 may be configured in a shape such as a circular hole, a strip-shaped hole, or a square hole, which is not limited in this embodiment.

如图1所示,在本实施例中,第二通风孔310设置在壳体300的周侧面上,这样能够避免风冷电池箱上部的异物或灰尘掉落至电池模组200内部,提高风冷电池箱的可靠性和稳定性。示例性地,第二通风孔310可以设置在壳体300的某一个、某几个周侧面上或者设置在四个周侧面上。且第二通风孔310可以设置为圆形孔、条形孔、方形孔等形状,本实施例对此不作限定。As shown in Fig. 1, in this embodiment, the second ventilation holes 310 are arranged on the peripheral side of the casing 300, which can prevent the foreign objects or dust on the upper part of the air-cooled battery box from falling into the inside of the battery module 200 and improve the ventilation. Reliability and stability of the cold battery box. Exemplarily, the second ventilation hole 310 may be provided on one, certain several peripheral sides or on four peripheral sides of the casing 300 .
