In this embodiment, the number of the multi-ribbed ice cold storage tubes is plural, and the multi-ribbed ice cold storage tubes are divided into plural groups, and each group of multi-ribbed ice cold storage tubes includes plural multi-ribbed ice cold storage tubes stacked up and down. Preferably, in the two multi-ribbed ice cold-storage tubes stacked up and down at will, the positions of the V-shaped plates 11 in the multi-ribbed ice cold-storage tubes at the upper layer are in one-to-one correspondence with the positions of the V-shaped plates 11 in the multi-ribbed ice cold-storage tubes at the lower layer, so that each group of multi-ribbed ice cold-storage tubes can construct a plurality of axial flow passages surrounding the multi-ribbed ice cold-storage tubes (that is, when a plurality of multi-ribbed ice cold-storage tubes in the same group are overlooked, only the multi-ribbed ice cold-storage tube at the uppermost layer can be seen, and all the areas of other multi-ribbed ice cold-storage tubes are blocked by the multi-ribbed ice cold-storage tubes at the uppermost layer), thereby enabling the smooth circulation of the cold-carrying agent, reducing the fluid resistance of the cold-carrying agent, enabling the uniform distribution of the flow rate of the cold-carrying agent, reducing the power consumption of the cold-carrying agent circulating pump, saving energy, and the uniform distribution of the flow rate of the cold-carrying agent, and the heat exchange efficiency of the cold-carrying agent.
The working principle of the ice cold accumulation tank is briefly described as follows:
the secondary refrigerant (usually ethylene glycol) which is introduced into the tank body 6 from the liquid inlet flows through the rib surfaces of the multi-rib ice cold storage tube, and the secondary refrigerant and the icing medium (water or aqueous solution) in the multi-rib ice cold storage tube transfer heat and exchange heat through the rib walls of the multi-rib ice cold storage tube, so that the water in the multi-rib ice cold storage tube is frozen through the cooling phase change.
The thawing and releasing process is that the refrigerating medium (usually glycol) flows through the surface of the multi-rib ice cold storage tube, and the refrigerating medium transfers heat with the ice in the multi-rib ice cold storage tube through the rib wall of the multi-rib ice cold storage tube, so that the ice in the multi-rib ice cold storage tube is thawed and released; the process of ice melting is that the secondary refrigerant starts to melt ice through the heat transfer between the rib wall of the multi-rib ice cold storage tube and the ice layer clung to the inner wall of the tube, the ice layer clung to the inner wall of the tube is melted into aqueous solution firstly, then the secondary refrigerant transfers heat and exchanges heat to the ice layer of the tube core through the rib wall and the water layer in the tube, the process is that the secondary refrigerant flows through the surface of the rib wall of the multi-rib ice cold storage tube, and then flows through the surface of the rib wall of the multi-rib tube 1, the water layer in the tube, the ice layer in the tube and the ice, and the three processes transfer heat and exchange heat, so that the ice in the tube exchanges heat with the secondary refrigerant to realize the ice melting and the cold releasing;
in the process of ice melting, the rib inner space of the multi-rib ice cold storage tube belongs to an array separation structure, ice melting water in the tube is increased, the thickness increase of the ice melting water layer is limited by the thickness of the multi-rib space separated by the array, and the heat exchange thermal resistance of the refrigerating medium through the wall of the multi-rib ice cold storage tube and the ice layer in the tube is limited by the thickness range of the multi-rib space separated by the array, so that the heat exchange efficiency of the refrigerating medium and the ice layer is greatly improved.
The foregoing description is only of the optional embodiments of the present invention, and is not intended to limit the scope of the invention, and all the equivalent structural changes made by the description of the present invention and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the invention.
