Thermoelectric refrigerating drink quick-freezing machine
The present invention relates to a kind of refrigeration machine, especially be suitable for the scene and mix the making of the draft beer of carbon dioxide and carbonated drink cold drink and other kinds cold drink occasion is provided.
Traditional beverage cooling device adopts the freon refrigeration machine, and this equipment is owing to adopting fluorine Lyons as cold-producing medium ozone layer to be had destruction and progressively being stopped using by the international convention time limit.Semiconductor thermoelectric refrigeration can overcome above-mentioned shortcoming, as Chinese patent application 94246875.9 and 95100353.4, but their structure is monoblock type, the manufacturing process difficulty is higher, and owing to be with water tank in the structure, make water participate in heat exchange and cause the beverage cooling rate to reduce, the water in the water vat pollutes the refrigeration environment if often do not change smelly easily.
At the shortcoming that above-mentioned prior art exists, task of the present invention provides in a kind of non-monolithic structure, the heat exchanger not water and participates in, and adopts the dry type thermoelectric cooling drink quick-freezing machine of thin slice riveting dress radiator and computer temperature control system.
The present invention will implement with following technical measures, it is by (Fig. 1) aluminum barrel, drink pipeline, the thermoelectric cooling assembly, radiator and acquisition of signal and treatment system constitute, described aluminum barrel is the stagewise cylinder, it is in aggregates by drink pipeline and aluminium casting, separate with heat insulation loop pad 6 between aluminum barrel and the aluminum barrel, the aluminum barrel center is the cavity of storage of water not, described radiator 5 is foil riveting assembling structure (Fig. 2, Fig. 3), 12 is foil, by rivet 11 and metal intermediate plate 13 foil 12 is coupled to a radiator, between backing plate 14 and crossbeam 16, places a steel ball 15.By being fixed in two screws and crossbeam 16, steel ball 15 and the backing plate 14 on the cold junction aluminum barrel, radiator 5 is pressed on the thermoelectric cooling assembly 4.Above-mentioned refrigerator also can be made squarely and many plates combined shaped to constitute the cold house of difformity and size.
Advantage of the present invention is, because aluminum barrel is the multilevel hierarchy form, radiator is the foil riveting assembling structure of small-sized efficient, owing to adopt crossbeam steel ball and backing structure in the radiator, radiator closely is pressed on the thermoelectric cooling assembly again, total Energy Efficiency Ratio of whole refrigeration machine is significantly improved, owing to adopt the small-sized efficient radiator, the volume and weight of refrigeration machine is reduced significantly, cost reduces, manufacture process requirement reduces, and for ease of maintenaince and promote the use of.
Description of drawings is as follows:
Accompanying drawing 1: refrigeration machine aluminum barrel structure principle chart;
Accompanying drawing 2: heat spreader structures schematic diagram;
Accompanying drawing 3: radiator connects schematic diagram with the thermoelectric cooling assembly;
Accompanying drawing 4: characteristic curve, ordinate are that Energy Efficiency Ratio ε/(%), abscissa is effective temperature difference Δ Te/ (1 °)
That the invention will be further described is as follows below in conjunction with accompanying drawing:
Last aluminum barrel 2 is formed by drink pipeline 3 and aluminium casting with following aluminum barrel 10, separate with heat insulation loop pad 6 between two cylindrical shells, the upper end of last aluminum barrel 2 and loam cake 1 are held, following aluminum barrel 10 lower ends connect with chassis 9, establish thermoelectric cooling assembly 4 around the aluminum barrel, by being fixed in two screws and crossbeam 16, steel ball 15 and the backing plate 14 on the cold junction aluminum barrel, radiator 5 is pressed on the thermoelectric cooling assembly.8 is the heat insulation polyamine ester foamed plastic.The capacity of this instant freezer is 350W, capacity is 500W during forced refrigeration, cryogenic temperature is-5 °---17 °, 5 °-15 ° of beverage temperatures, supply 50-80 liters/hours of capacity for liquor, cooling rate is greater than 1 °/minute, and this refrigerator can need be assembled into the draft beer instant freezer by the user, carbonated drink instant freezer, three warm beverages and refrigeration and cold drink dual-function machine etc.Fig. 4 is the characteristic curve of result of the test of the present invention, and ordinate is that Energy Efficiency Ratio ε/(%), abscissa is effective temperature difference Δ T
