本实施例具体控温运行过程如下：假定环境温度为25℃，容器5.13中的相变材料为－20℃，但相变材料相变温度为-18℃，冷链箱中放入的食品为6℃，通过触摸显示屏5.21或监控平台设置冷链箱内温度控制范围为2℃到5℃。控制主板5.2通过各个传感器采集信息后，经过设定的算法模型控制主板会驱动导热控制阀5.23连接上下两层的金属导热板5.11，使得冷链箱体内的热量通过金属导热板5.11传导到容器5.13中的相变材料中，同时冷链箱体内的温度开始下降；当冷链箱体内的温度下降到2℃时，主板控制器2.1会驱动导热控制阀5.23断开上下两层的金属导热板5.11的连接，此时容器5.13中的相变材料停止吸收冷链箱体内的热量，冷链箱体内的温度也开始慢慢上升，直到再次上升到5℃时控制主板再次驱动导热控制阀5.23连接上下两层的金属导热板5.11……重复此运行动作直到相变材料温度与箱体6内温度相同为止；当控制主板5.2采集到相变材料温度高于－17℃时会发出警告，说明容器5.13内的相变材料相变已结束，只要在容器5.13温度上升到5℃之前 更换已冷冻好的容器5.13就可继续自动控制冷链箱体内的温度在2℃到5℃的范围内。The specific temperature control operation process of this embodiment is as follows: assuming that the ambient temperature is 25°C, the phase change material in the container 5.13 is -20°C, but the phase change temperature of the phase change material is -18°C, and the food placed in the cold chain box is 6℃, set the temperature control range of the cold chain box to 2℃ to 5℃ through the touch screen 5.21 or the monitoring platform. After the control board 5.2 collects information through various sensors, the control board will drive the heat conduction control valve 5.23 to connect the upper and lower metal heat conduction plates 5.11 through the set algorithm model, so that the heat in the cold chain box is conducted to the container 5.13 through the metal heat conduction plate 5.11 In the phase change material, the temperature in the cold chain box begins to drop at the same time; when the temperature in the cold chain box drops to 2°C, the motherboard controller 2.1 will drive the heat conduction control valve 5.23 to disconnect the upper and lower metal heat conduction plates 5.11 At this time, the phase change material in the container 5.13 stops absorbing the heat in the cold chain box, and the temperature in the cold chain box starts to rise slowly, until it rises to 5℃ again, the control board drives the thermal control valve again 5.23 connects up and down Two-layer metal heat-conducting plate 5.11... Repeat this operation until the temperature of the phase change material is the same as the temperature in the box 6; when the control board 5.2 collects that the temperature of the phase change material is higher than -17℃, a warning will be issued, indicating that the container 5.13 The phase change of the phase change material inside has ended.
