Description

Technical Field

[0001] The utility model relates to the technical field of condensation evaporators, in particular to a carbon dioxide deep-cold condensation evaporator. Background Art

[0002] Liquid carbon dioxide refers to carbon dioxide gas liquefied into liquid form under high pressure and low temperature. Liquid carbon dioxide is a refrigerant that can be used to preserve food. When liquid carbon dioxide is used to freeze food, it can improve the frozen freshness of the food because the freezing process isolates oxygen.

[0003] The condenser evaporator is a multi-layer plate fin. The cold and hot fluids in each channel are well heat exchanged through the plate fins and partitions. The condenser evaporator is generally placed between the upper and lower towers. The nitrogen rising from the lower tower is condensed inside it, and the liquid nitrogen refluxed from the upper tower is evaporated inside it. This process is mainly achieved based on the different boiling points of high-pressure nitrogen and low-pressure nitrogen, and there is a certain temperature difference. The condenser evaporator is used in cascade refrigerators.

[0004] In the use of carbon dioxide refrigeration equipment, the condenser evaporator is one of the essential components. When the current carbon dioxide deep cooling condenser evaporator is in use, condensed water will be produced when the condenser evaporator is working, and the dripping of condensed water will affect the surrounding environment. Therefore, it is necessary to improve it. Utility Model Content
