Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] see figure 1 , 2. The present invention includes a shell 4 provided with a heat exchange working medium inlet 7 and a heat exchange working medium outlet 8, and several layers are arranged in the shell 4 with a refrigerant inlet 1 and a refrigerant outlet 6 without an inner core. Bending tube technology A serpentine heat exchange tube formed at one time. The bend angle of the serpentine heat exchange tube is greater than 180°, and the elbows at both ends are close together (or very close), which greatly reduces the space of the heat exchanger. The volume of the straight pipe section accounts for 70% of the total length. As we all know, when the fluid flows in the straight pipe section, there is only frictional resistance along the way without excessive local resistance caused by the change of flow direction, so the fluid flow in the straight pipe secti...
