在实际应用过程中，若箱体1内的空气温度较低，高防护等级下可以认为绝对湿度一定，通过启动给冷却液加热，液冷板加热电池7和箱体1内的空气，从而降低了箱体1内的空气相对湿度。In actual application, if the air temperature in the box 1 is low, the absolute humidity can be considered to be constant under the high protection level. By starting to heat the coolant, the liquid cooling plate heats the battery 7 and the air in the box 1, thereby reducing The relative humidity of the air in the casing 1 has been improved.

The above-mentioned heat sinks can also be distributed in other ways, and are not limited to the above-mentioned embodiments. For example, if the outer wall of the condensing pipe section of the inlet pipe is provided with a heat dissipation structure 6, the heat dissipation structure 6 is a cooling fin, and there are at least two cooling fins distributed sequentially along the axial direction of the condensation pipe section of the inlet pipe. The condensing pipe sections are coaxial; if the outer wall of the above-mentioned outlet condensing pipe section is provided with a heat dissipation structure 6, the heat dissipation structure 6 is a cooling fin, and there are at least two cooling fins and are distributed sequentially along the axial direction of the outlet pipe condensing pipe section.

Specifically, the above-mentioned liquid cold plate includes a liquid cold plate body 2, and the liquid cold plate body 2 includes: a first liquid cold plate portion 21 for placing the battery 7 and a second liquid cold plate portion 22 for not placing the battery 7; Wherein, the second liquid cooling part includes a second liquid cooling plate part 22 , and the condenser is arranged on the second liquid cooling plate part 22 .
在实际应用过程中，可选择冷凝器为单独的部件并设置在第二液冷板部22上，也可选择上述冷凝器包括第二液冷板部22的部分或者全部，根据实际需要选择。In practical application, the condenser can be selected as a separate component and arranged on the second liquid-cooled plate portion 22 , or the above-mentioned condenser can be selected to include part or all of the second liquid-cooled plate portion 22 , depending on actual needs.
为了简化结构，选择冷凝器包括整个第二液冷板部22或第二液冷板部22 的部分。可以理解的是，上述第一液冷部包括上述第一液冷板部21，第二液冷板部22的导热系数大于第一液冷板部21的导热系数。In order to simplify the structure, the condenser is selected to include the entire second liquid-cooled plate part 22 or a part of the second liquid-cooled plate part 22 . It can be understood that the first liquid cooling part includes the first liquid cooling plate part 21 , and the thermal conductivity of the second liquid cooling plate part 22 is greater than that of the first liquid cooling plate part 21 .
在实际应用过程中，由于第一液冷板部21需要放置电池7，则第一液冷板部21设置有绝缘导热层，而第二液冷板部22无需设置绝缘导热层，从而使得第二液冷板部22的导热系数大于第一液冷板部21的导热系数。当然，也可通过其他方式实现第二液冷板部22的导热系数大于第一液冷板部21的导热系数，本实施例对此不做限定。In actual application, since the first liquid cooling plate part 21 needs to place the battery 7, the first liquid cooling plate part 21 is provided with an insulating and heat conducting layer, while the second liquid cooling plate part 22 does not need to be provided with an insulating and heat conducting layer, so that the second liquid cooling plate part 22 does not need to be provided with an insulating and heat conducting layer. The thermal conductivity of the second liquid cold plate part 22 is greater than the thermal conductivity of the first liquid cold plate part 21 . Certainly, other ways may also be used to realize that the thermal conductivity of the second liquid-cooled plate portion 22 is greater than the thermal conductivity of the first liquid-cooled plate portion 21 , which is not limited in this embodiment.

若第一液冷通道和第二液冷通道23并联，第二液冷通道23的流量小于第一液冷通道的流量，这样，可减小流经第二液冷通道23的冷却介质的使用量，降低了成本。当然，也可选择第二液冷通道23的流量大于或等于第一液冷通道的流量，并不局限于上述实施例。If the first liquid cooling channel and the second liquid cooling channel 23 are connected in parallel, the flow rate of the second liquid cooling channel 23 is less than the flow rate of the first liquid cooling channel, so that the use of the cooling medium flowing through the second liquid cooling channel 23 can be reduced volume, reducing costs. Certainly, the flow rate of the second liquid cooling channel 23 may also be selected to be greater than or equal to the flow rate of the first liquid cooling channel, and is not limited to the above-mentioned embodiment.
上述储能装置的除湿结构中，为了进一步提高可靠性，可选择第一液冷板部21高于第二液冷板部22，这样，即使第一液冷板部21上出现冷凝水，由于第一液冷板部21高于第二液冷板部22，则第一液冷板部21上的冷凝水会自第一液冷板部21流下，例如，流至第二液冷板部22，从而减小了电池7外壳通过冷凝水形成短路的几率。In the above-mentioned dehumidification structure of the energy storage device, in order to further improve reliability, the first liquid-cooled plate part 21 can be selected to be higher than the second liquid-cooled plate part 22, so that even if condensed water appears on the first liquid-cooled plate part 21, due to The first liquid cooling plate part 21 is higher than the second liquid cooling plate part 22, then the condensed water on the first liquid cooling plate part 21 will flow down from the first liquid cooling plate part 21, for example, flow to the second liquid cooling plate part 22, thereby reducing the probability of short circuit formed by the condensed water in the case of the battery 7.
上述冷凝器上形成的冷凝水较易流至电池7，为了避免出现上述问题，可选择上述储能装置的除湿结构还包括冷凝水收集部5，冷凝水收集部5用于收集空气在冷凝器上所冷凝出的冷凝水。这样，有效避免了冷凝水流至电池7处，进一步减小了电池7的外壳通过水形成短路的几率，进一步提高了安全可靠性。The condensed water formed on the above-mentioned condenser is easier to flow to the battery 7. In order to avoid the above-mentioned problems, the dehumidification structure of the above-mentioned energy storage device can also be selected to include a condensed water collection part 5, which is used to collect air in the condenser Condensed water condensed from above. In this way, the condensed water is effectively prevented from flowing to the battery 7, and the probability of short circuit formed by the shell of the battery 7 through water is further reduced, and the safety and reliability are further improved.
