Abstract
A finned tube ice cold-storage device belongs to the cold storage engineering field, which comprises a cold storage tank, a cold storage medium, finned tubes, an inlet header, an outlet header, a medium inlet pipe connection, a medium outlet pipe connection, a drain pipe, a replenishing pipe and the like. A refrigerant or a secondary refrigerant is put in a heat transfer cylinder which is composed of finned tubes via the medium inlet pipe connection, and the refrigerant or the secondary refrigerant which transfers heat with the cold storage medium in the cold storage tank via the heat transfer cylinder flows out from the medium outlet pipe connection. Compared with traditional ice cold-storage devices, the finned tube ice cold-storage device not only can effectively enlarge ice-making area or ice-melting area, reduce additional thermal resistance caused by expansion of an ice layer, further achieve a more compact and higher effective structure, but also can effectively increase cold storage rate and cold release rate, and improve running status of refrigerating machines.
Description
Technical field:
Title of the present utility model is a kind of finned tube Cold-storage using ice, belongs to cold-storage engineering field.
Background technology:
Along with the expansion of development and national economy, city size and the change of power structure, peak load is the trend of quick growth, most of urban distribution networks are faced with the situation of peak power deficiency, valley power surplus, the peak-valley difference of each big electrical network has all surpassed 30% of peak load, and is indivedual even reach 50%.The peak-valley difference of Zeng Jiaing has brought sizable difficulty for the peaking operation of electrical network year by year, therefore, how to realize that by the load of adjusting user side " peak load shifting ", balanced load have become a problem demanding prompt solution.For this reason, the peak and valley time electrovalence policy has been formulated in each province and city successively, encourages the user to develop valley power, farthest utilize existing power equipment, realizes " peak load shifting ", alleviates the contradiction of electrical network peak short of electricity.Wherein, ice storage technology is an important technique measure that realizes electric power " peak load shifting " scheme.
From domestic and foreign literature and license situation, at present to adopt maximum be static ice making to the Cold-storage using ice ice making mode on the engineering, and its heat-transfer surface is various coiled, board-like or various seal, and dynamic ice-making is less.In static ice making, because employing is tubular type or board-like surface, therefore, the ice making area in the unit volume is less, and the ice making rate can reduce gradually along with the carrying out of ice-making process.The utility model patent proposes to utilize fin tube structure as the cold-storage concept of component, can solve effectively that the heat transfer property that traditional coiled structure, plank frame and packaged type structure Cold-storage using ice exist is poor, the regenerator volume big, structure is not compact and hold, put problems such as the cooling rate rate is low.
The utility model content:
The technical problems to be solved in the utility model provides a kind of high-efficiency compact formula Cold-storage using ice.Store the cold that electronic refrigeration produces in the low power consumption phase at night, peak times of power consumption discharge cold by day, satisfy the needs of producing or living, therefore, not only can farthest utilize existing power equipment, realize " peak load shifting ", alleviate the contradiction of electrical network peak short of electricity, and can improve generating set operation conditions, improve unit operation efficient, reduce environmental pollution, simultaneously, also can reduce the installed capacity of refrigeration unit, guarantee refrigeration unit operation efficiently and stably under approaching full load.
For solving the problems of the technologies described above, the technical scheme of a kind of plate-fin Cold-storage using ice of the utility model is as follows:
A kind of finned tube Cold-storage using ice of forming by cold-storage groove, cool storage medium, finned tube, inlet header, outlet header, medium entrance sleeve, media outlet adapter, discharging tube and liquid supplementation pipe, cold-producing medium or refrigerating medium enter the heat exchange core body that is made of finned tube by the medium entrance sleeve, and cold-producing medium or refrigerating medium take over to be flowed out by media outlet after by the cool storage medium heat exchange in heat exchange core body and the cold-storage groove; Cold-producing medium or refrigerating medium import and export are taken over and are laid respectively at the lower and upper of core body, and link to each other with the import and export header respectively; Cold-producing medium or refrigerating medium are evenly distributed in every group of finned tube by inlet header, gather outflow at outlet header then; Cold-producing medium or refrigerating medium flow in pipe, and cool storage medium is positioned at outside the finned tube; In addition, for the liquid level of the cool storage medium in the adjustment cold-storage groove and the needs of operation maintenance, at the upper and lower liquid supplementation pipe and the discharging tube of being equipped with of cold-storage groove.
The utility model is characterised in that cold-producing medium or refrigerating medium flow with traditional coiled and the board-like surface of high-efficiency fin pipe heat exchange surface replacement in finned tube, cool storage medium participates in heat exchange outside finned tube, and the outer fin of pipe adopts the ratio-frequency welding ring fin.Compare with traditional Cold-storage using ice, not only can expand ice making or ice-melt area effectively, reduce the additional thermal resistance that brings that thickens owing to ice sheet, structure is compact efficient more, and can improve effectively and hold, put the cooling rate rate, improves the operation conditions of refrigeration machine.
Description of drawings:
Fig. 1 is a kind of structure chart of finned tube Cold-storage using ice, Fig. 2 be among Fig. 1 A to perspective view.Wherein: the 1-cold-storage groove; The 2-cool storage medium; The 3-finned tube; The 4-inlet header; The 5-outlet header; 6-medium entrance sleeve; The 7-media outlet is taken over; The 8-discharging tube; The 9-liquid supplementation pipe.
The specific embodiment:
Fig. 1 represents that also a cold storage capacity is a kind of finned tube Cold-storage using ice of 100kWh.
When cold-producing medium or refrigerating medium entered the heat exchange core body that is made of finned tube 3 by medium entrance sleeve 6, cold-producing medium or refrigerating medium were taken over 7 by media outlet after by cool storage medium 2 heat exchange in heat exchange core body and the cold-storage groove 1 and are flowed out.Cold-producing medium or refrigerating medium import and export are taken over and are positioned at the lower and upper of core body, and link to each other with outlet header 5 with inlet header 4 respectively; Cold-producing medium or refrigerating medium are evenly distributed in every group of finned tube 3 by inlet header 4, gather outflow at outlet header 5 then; Cold-producing medium or refrigerating medium flow in pipe, and cool storage medium is positioned at outside the finned tube.In addition, for the liquid level of the cool storage medium in the adjustment cold-storage groove and the needs of operation maintenance, at the upper and lower liquid supplementation pipe 9 and the discharging tube 8 of being equipped with of cold-storage groove.Through measuring and calculating, ice making or ice-melt area reach (70-300) m in this high-efficiency compact formula Cold-storage using ice unit volume
2/ m
3Compare with sealed with traditional coiled, average ice making and ice-melt speed improve (20-30) %, and heat transfer temperature difference reduces about about 1 ℃.
