Be connected with in parallel the mixing for being connected in series or being connected in parallel or connecting between the described heat exchanger tube of different rows.At the multiple connected mode of heat exchanger tube, help to widen the scope of application of regenerative heat exchanger, can decide as required according to concrete use occasion.
Described heat exchange unit surface arrangement has a plurality of fins.Being provided with of fin can be strengthened the heat exchange effect.
The right lip-deep fin of described adjacent heat exchange unit is crisscross arranged.But the heat exchange effect is further strengthened in the enhance fluid turbulent fluctuation that is crisscross arranged of fin.
The present invention compared with prior art has following advantage:
1. this heat exchanger can carry out the heat exchange between solid, liquid, gas or solid, liquid, three kinds of form media of liquid simultaneously, can be applicable to multiple particular application such as thermal storage and energy accumulation, multiple medium heat exchange.
2. through test run, this heat exchanger heat exchange is respond well.
3. this heat exchanger can carry out pro forma combination, variation according to actual operating position, and is applied widely.

The specific embodiment
Below in conjunction with the drawings and specific embodiments content of the present invention is described in further details.
Embodiment:
See also Fig. 1 to shown in Figure 6, a kind of regenerative heat exchanger, include housing 5, on this housing 5, offer first fluid inlet 2 and first fluid outlet 1, parallel zigzag weld is connected to many row's heat exchange units 7 in the housing 5, all be reserved with the space between the adjacent heat exchange unit 7 and between heat exchange unit 7 and housing 5 inwalls, this space forms first fluid heat exchanger channels 8, and these first fluid heat exchanger channels 8 head and ends are communicated with first fluid outlet 1 and first fluid inlet 2 respectively;
Be laid with heat exchanger tube 6 in the heat exchange unit 7, form the second fluid heat exchanger channels 12 in different row's heat exchanger tubes 6, can adopt between different rows' the heat exchanger tubes 6 series, parallel, earlier several rows of series connection again various ways such as parallel connection link together, decide on concrete application scenario, offer second fluid intake 4 and second fluid issuing 3 on housing 5, these second fluid heat exchanger channels, 12 head and ends are communicated with second fluid intake 4 and second fluid issuing 3 respectively; By two groups of above-mentioned fluid inlet and outlets, can in heat exchanger, pass in and out to carry out heat exchange for two kinds of fluids;
