The specific embodiment
Below in conjunction with Figure of description this device is further specified:
A kind of changeable type phase change heat accumulator; Comprise heat storage container 14, phase change heat storage material 3, heat source fluid import 12, heat source fluid outlet 13, water inlet 11 and delivery port 10; Described phase change heat storage material 3 is contained in the heat accumulation pipe; Heat accumulation pipe is formed heat accumulation pipe row through location-plate 5, and many group heat accumulation pipe rows are housed in the heat storage container 14.
Like Fig. 2, the heat accumulation pipe shown in 3 is bimetallic tube, and outer tube 2 is six rib pipes, can guarantee that the maximum deployment tube number of heat exchange area in unit are is maximum, and interior pipe 1 is a pipe, supports through fin 4 between interior pipe 1 and the outer tube 2, and fin 4 can increase heat transfer area.In fin 4 is cut apart between pipe 1 and the outer tube 2 interlayer be a plurality of spaces, be filled with phase change heat storage material 3 in the space of cutting apart, the fin 4 that passes through of the thermal source that gets into from interior pipe 1 imports the phase change heat storage material 3 heat fast into, thereby improves exchange capability of heat and efficient.Phase change heat storage material 3 in the heat accumulation pipe can regularly replace, or changes phase change heat storage material 3 according to on-the-spot heat storage capacity, strengthens heat storage capacity, prolongs the service life of regenerative apparatus.Heat accumulation pipe row be installed in the heat storage container 14 through upper end sealing gland 8 and lower end sealing gland 9; Can realize heat accumulation pipe in heat storage container 14 the location and guarantee between the heat accumulation pipe a certain amount of gap to be arranged, make the heat exchanging fluid medium and then realize heat exchange along Gap Flow.Heat accumulation pipe quantity on the heat accumulation pipe row can be adjusted, and realizes that the mobilism of heat storage container 14 heat storage capacities is regulated.End cap on the heat storage container 14 is connected with heat storage container 14 with encapsulant 7 through screw, makes things convenient for the maintenance of device and heat accumulation pipe row's replacing.Heat storage container 14 heat source fluid imports 12 are communicated with the interior pipe of heat source fluid outlet 13 through heat accumulation pipe.Water inlet 11 is in the bottom of heat storage container, and delivery port 10 makes the flow reversal heat exchange on the top of heat storage container, realizes high efficient heat exchanging.
Narrate the workflow of this device below:
Thermal source gets into heat storage container 14 from heat source fluid import 12 during accumulation of heat; Arrive heat source fluid outlet 13 through pipe in the heat accumulation pipe; Heat source fluid is managed in heat accumulation pipe in 1 and is flowed, and transmits heat through interior pipe 1 wall and gives phase change heat storage material 3, phase change heat storage material 3 stored energys.
Cold water gets into the Clearance Flow as shown in Figure 5 that heat accumulation pipe outer tubes 2 form through water inlet 11 during heat release, so with the outer tube 1 wall contact heat-exchanging of heat accumulation pipe, the water after the heating flows out from delivery port 10.
This device can first accumulation of heat, and heat release again when the needs thermal source realizes discontinuous operation; Also accumulation of heat on one side exchanges heat on one side for, realizes continuous operation.8 couples of heat accumulation pipe rows of end cap 6 and upper end sealing gland that can open this device simultaneously change, also can change the phase-change material in the heat accumulation pipe on the heat accumulation pipe row, thus the dynamic adjustable joint of realization phase-transition heat-storage.
