Detailed description of the invention
The structure of the present invention is concentric casing tube phase-change regenerative heat exchanger, and heat exchanging fluid can use solar heat
Water, heat accumulating phase change material may select paraffin, fatty acid or fuse salt, and preferred heat accumulating phase change material is paraffin.
Seeing that Fig. 5, spiral flow guide bar 14 are slab type spiral spring structure, spiral flow guide bar 14 is solid
It is scheduled between inner sleeve 6 wall and outer sleeve 5 wall formation spiral flow-guiding channel 4.Spiral level is led
Stream bar 8 is clock-spring connectors structure, fixes spiral level between upper strata bottom cover 9 and lower floor's bottom cover 10
Flow guide bar 8 forms spiral horizontal channel 11.Water conservancy diversion standpipe 3 lower port is with spiral horizontal channel 11 central authorities even
Logical, the outlet of side, spiral horizontal channel 11 connects with spiral flow-guiding channel 4.
See Fig. 1 and the water movement direction of arrow therein；Paraffin can be stored in inner sleeve inner chamber 13,
Being applied in combination with solar thermal collector, during daytime, solar temperature is high, makes water flow through solar thermal collector, becomes
High-temperature water enters water conservancy diversion standpipe 3, enters spiral flow-guiding channel 4 through spiral horizontal channel 11, from outlet
Pipe 15 is discharged.First solar water is through water conservancy diversion standpipe 3, and it is internal that water conservancy diversion standpipe 3 is positioned at inner sleeve 6,
Heat can be conducted to the paraffin inside inner sleeve inner chamber 13, heat can be prevented again to scatter and disappear；Secondly solar energy
Hot water from spiral horizontal channel 11 central authorities with helical flow pattern enter spiral flow-guiding channel 4, again,
Solar water is discharged from from outlet 15, and after-heat is fully conducted to the stone in inner sleeve inner chamber 13
Wax, thus utilize solar heat by paraffin melting.Tap water is made night to flow through water conservancy diversion standpipe 3, from outlet
15 discharge, the tap water in Topography water conservancy diversion standpipe 3 stored by the paraffin in inner sleeve inner chamber 13,
Domestic hot-water can be provided.Compare with existing heat exchanger, add heat exchange area, enhance exchanger base
Heat exchange efficiency；Radiated rib 12 is fixed on above upper strata bottom cover 9, interval configuration, and its height dissipates with adjacent
The ratio of the spacing between hot fin, at 4-10, can have optimal biography with the diabatic process of enhanced heat exchange fluid
Thermal effect；Cone baffle 7 being provided below in water conservancy diversion standpipe 3 lower port, cone baffle 7 is fixed
On lower floor's bottom cover 10, solar water uniform divided flows water conservancy diversion can be made to enter spiral horizontal channel 11,
Can effectively alleviate the liquid hit phenomenon of solar water；Top communicating pipe 1 can input to the inner chamber 13 of inner sleeve
Heat accumulating phase change material paraffin.
The use temperature of this phase change thermal storage heat exchanger is relatively low, owing to heat of transformation potential metric density is very big, so
Heat exchanger volume need not be large and can meet routine use demand.
Present invention can also apply to industrial afterheat recovery and recycling.In the industrial production, usually have perhaps
Many industrial exhaust heats cannot utilize, the washing slag water of such as blast furnace, industrial equipment cooling water etc., can use this
Invention is by industrial afterheat recovery, and is temporarily stored in paraffin by heat, as stable thermal source quantity of heat given up.
The present invention can also be moving heat source car with automobile combination, is absorbed by industrial exhaust heat after storing, heat
Temporarily store, utilize moving heat source car to realize the space transfer of heat, as hotel, bath center,
Residential building uses, and moving heat source car has certain motility and mobility, improves heat utilization rate.
