Background technology
At present, solar heating engineering adopts many solar thermal collectors and hot water storage tank and water pump to carry out series circulation mostly, make the water temperature raising back of hot water storage tank and water pump standby, this mode easily makes scaling in the thermal-collecting tube after having the long-term directly circulation of employing running water, heat absorption rate constantly descends, defective such as easy cleaning not again, improved mode is a binary cycle system, solar energy collector system adopts the heat-carrying agent of non-scaling, enter heat exchanger after the heat absorption, pass to the running water of hot water storage tank system, for solving the problem of rainy weather water temperature deficiency, again at the other large power, electrically heater in parallel of heat exchanger, as auxiliary thermal source, shortcomings that these devices exist are pipeline valve more complicated, and the time-consuming effort again of handover operation remains follow-up improvement.
Summary of the invention
The purpose of this utility model is to design a kind of double acting heat exchanger, and this heat exchanger can reduce quantity such as equipment, pipeline and valve, can reach exchange heat and auxiliary electrically heated double action in two circulating solar energy hot-water heating systems.
According to design provided by the utility model, heat exchanger tube is set in heat exchange segment, hot water outlet and medium are set on heat exchange segment to be imported and exported, it is characterized in that: on heat exchange segment, also connect electric heater section, electric heater and cooling water inlet are set on electric heater section, and the hot water outlet end of electric heater section is connected with the cooling water inlet end of heat exchange segment.
Heat exchange segment be positioned at electric heater section above, hot water outlet is positioned at the upper end of heat exchange segment, medium is imported and exported the side be positioned at heat exchange segment, and the shell and tube heat exchanger tube is set in heat exchange segment, and the approximate dividing plate that intersects vertically with the shell and tube heat exchanger tube.Upper end in heat exchange segment is provided with exhaust outlet, in the lower end of heat exchange segment the dewatering outlet is set.Sewage draining exit is set below electric heater section.
Upper end in heat exchange segment is provided with loam cake, and an outlet plenum is formed at the top in heat exchange segment, and hot water outlet is positioned on the outlet plenum, and the import and export of every heat exchanger tube are communicated with the port of export and the outlet plenum of electric heater section respectively.
The utility model has the advantages that: heat exchange segment and electric heater section are fused, pipe arrangement and valve in the solar heating engineering system have been reduced, reduced the total cost of equipment, avoided loaded down with trivial details handover operation fully, just can implement switching between solar energy heating and electrical heating as long as utilize electrical appliance button, cooperate automatic operation system, can realize Automatic Control.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is user mode figure of the present utility model.
The specific embodiment
As shown in the figure: in heat exchange segment 3, heat exchanger tube is set, hot water outlet 12 and medium are set on heat exchange segment 3 import and export 11,9, on heat exchange segment 3, also connect electric heater section 4, perisporium at electric heater section 4 is equipped with 4 groups of electric heaters 7, electric heater 7 stretches into the inner chamber of electric heater section 4, all the time pile water in electric heater section 4, in the bottom of electric heater section 4 cooling water inlet 5 is set, the hot water outlet end of electric heater section 4 is connected with the cooling water inlet end of heat exchange segment 3.Electric heater section 4 bottoms are connected with supporting leg, this device are supported on the place of ground or needs.Medium on the heat exchange segment 3 is imported and exported 11,9 and is utilized pipeline 16,15 to be connected with solar thermal collector 17 respectively, and at outlet 9 and 17 installations of solar thermal collector medium circulation pump 19, hot water outlet 12 on the heat exchange segment 3 utilizes pipeline to be connected with hot water storage tank 18 and heat-exchanger pump 20 respectively with 5 of cooling water inlets on the electric heater section 4, also interconnects with pipeline at hot water storage tank 18 and 20 of heat-exchanger pumps.During medium circulation pump 19 normal operations, heat-carrying agent is entered 13 of the heat exchanger tubes of heat exchange segment 3 by thermal medium import 11, through dividing plate 10 bafflings, after cold water heat exchange in the heat exchanger tube 13, export 9 from thermal medium and discharge, after pipeline is delivered to solar thermal collector 17 heating, in entering heat exchange segment 3, medium import 11 participates in heat exchange again, circulation and so forth, constantly with the cold water in the heat transferred heat exchanger tube 13, the water heating in the hot water storage tank 18 the most at last.When overcast and rainy water temperature is not enough, just close medium circulation pump 19, connect electric heater 7 and heat-exchanger pump 20, make the cold water that enters in the electric heater section 4 from cooling water inlet 5 constantly be heated by electric heater 7, enter hot water storage tank 18 through heat exchanger tube 13 and hot water outlet 12 again.
Heat exchange segment 3 be positioned at electric heater section 4 above, hot water outlet 12 is positioned at the upper end of heat exchange segment 3, medium import and export 11,9 are positioned at the side of heat exchange segment 3, vertically arranged shell and tube heat exchanger tube 13 is set in heat exchange segment 3, and the approximate dividing plate 10 that intersects vertically with shell and tube heat exchanger tube 13, dividing plate 10 can prolong the flow process of heat-carrying agent, improves heat exchange efficiency.
