洛阳正奇机械有限公司开发生产的“500A-800A液冷充电枪+28型液冷线缆+液冷源”产品，其中的28型液冷线缆是一根集成电缆，绝缘外被内含十七根导线：DC+/DC-液冷线缆各一根；PE地线一根，其余是信号线。其内的DC+/DC-液冷线缆，它一端的接头是直流充电枪的导电端子，另外一端是DC+/DC-两个电极，其上设置有冷却液的接口。28型液冷线缆：28是指液冷集成电缆的外径是28mm，软体导线的截面是28mm2。

The product "500A-800A liquid-cooled charging gun + 28-type liquid-cooled cable + liquid-cooled source" developed and produced by Luoyang Zhengqi Machinery Co., Ltd., of which the 28-type liquid-cooled cable is an integrated cable, and the insulation Seventeen wires: one DC+/DC- liquid-cooled cable; one PE ground wire, and the rest are signal wires. The DC+/DC- liquid-cooled cable inside has a connector on one end that is the conductive terminal of a DC charging gun, and the other end has two electrodes, DC+/DC-, on which a coolant interface is set. Type 28 liquid-cooled cable: 28 means that the outer diameter of the liquid-cooled integrated cable is 28mm, and the cross-section of the soft wire is 28mm2.

ZQ液冷源重量20公斤；电机+散热风扇=300W；宽*高*厚=413mm*368mm*166mm；所用冷却液环保，可生物降解，绝缘阻燃。

ZQ liquid cooling source weighs 20 kg; motor + cooling fan = 300W; width * height * thickness = 413mm * 368mm * 166mm; the coolant used is environmentally friendly, biodegradable, insulating and flame retardant.

冷却方式：ZQ液冷源推动冷却液进入28型液冷电缆的DC+线缆，穿过软体导线到达国标充电枪的DC+导电端子，对DC+软体导线和导电端子进行冷却；然后流动的冷却液进入DC-导电端子返回进入DC-线缆，穿过软体导线；流动的冷却液带着充电产生的热回到ZQ液冷源的冷却单元散热降温后回到动力泵，动力泵推动冷却液连续不断在充电枪导电端子和电缆软体导线及液冷源之间循环流动进行冷热交换，解决现有充电技术中的高温发热问题。

Cooling method: The ZQ liquid cooling source pushes the coolant into the DC+ cable of the 28-type liquid-cooled cable, passes through the soft wire to the DC+ conductive terminal of the national standard charging gun, and cools the DC+ soft wire and the conductive terminal; then the flowing coolant enters The DC-conducting terminal returns to the DC-cable and passes through the soft wire; the flowing coolant takes the heat generated by charging and returns to the cooling unit of the ZQ liquid cooling source to dissipate heat and return to the power pump, which pushes the coolant continuously Circulating flow between the conductive terminal of the charging gun, the cable soft wire and the liquid cooling source for cold and heat exchange, solving the problem of high temperature heating in the existing charging technology.

基于GB20234.3-2015标准，洛阳正奇机械有限公司开发生产的500A-800A“液冷充电枪+28型液冷线缆+ZQ液冷源”，有三部分构成：GB20234.3-2015版；500A-800A28型液冷线缆；ZQ液冷源。
