Chinese patent CN201310085225.7 discloses a kind of heat pipe-type movement heat supply phase-change regenerative apparatus, and it includes tank
Body and conveying arrangement, tank body are fixed on conveying arrangement by pedestal using welding or bolt mode, and tank body is by laterally setting
Dividing plate is divided into two parts up and down, and top is regenerator, and bottom is heat source room, and regenerator in heat source room with being provided with heat source room
Heat pipe in heat transfer to regenerator.But the invention needs to give the heat transfer in heat source room to phase transformation material by heat pipe
Material, can be directly compared with thermal source fully contacts with phase-change material, and heat storage efficiency is not high, and speed is slow, in addition, the phase in regenerator
When becoming material accumulation of heat completion, need to dismantle accumulation of heat pipeline again, inconvenient for operation, this outer tank body outer cladding is common thermal insulation layer,
Equally exist the defects of heat insulation and preservation effect is bad.
Chinese patent CN201210455369.2 discloses a kind of combined type phase-change accumulation energy movement heat supply car, and it includes load-carrying
Automobile body and carriage of heat preservation, are provided with high, medium and low temperature phase change heat accumulator in carriage of heat preservation, and each phase change heat accumulator includes machine
Shell, is respectively arranged with corresponding phase-change material and heat exchanger in casing, and each phase change heat accumulator is fixedly connected on car by pedestal
On frame；It is sequentially connected between the heat exchanger of high, medium and low temperature phase change heat accumulator by connecting pipe.The invention can realize not equality of temperature
Spend the recovery of the waste heat of gradient or heat of having more than needed；In heat release, the steam or hot water of different temperatures can be produced.The invention employs three
Kind of composite phase-change material, but the thermal conductivity factor of three kinds of composite phase-change materials that uses of the invention is fixed and less；The invention
In, heat source fluid and running water are same pipelines in heat exchanger, because heat source fluid is generally waste water, waste gas, easily
The pipeline of heat exchanger is polluted, domestic water can be made or other potential safety hazard be present with water；The each phase change heat accumulator of the invention and
The connecting pipe (road) being laid in compartment uses Insulation, heat-insulation layer bottom using resistant to elevated temperatures rock wool, blanket of glass wool,
The materials such as ceramic fibre, insulation outermost layer use polyurethane foam material.The inwall of carriage of heat preservation also using polyurethane foam every
Heat, but the heat insulation effect of these materials is all not so good as aerogel heat-insulating material, and relative to these materials, aerogel heat-insulating material has
Significantly superior heat-proof quality.
Once there is proposal using barium hydroxide as phase-change heat accumulation medium, but barium hydroxide has big toxicity, supercooling, circulation
The problems such as difficult is reclaimed after stability is poor, phase transformation separation and regenerative apparatus are scrapped.
In addition, it is above-mentioned also exist in the prior art install or dismounting regenerative apparatus trouble, in terms of malfunction not
Foot.
A kind of accordingly, it is desirable to provide movement based on phase-change material that can overcome the above mentioned problem present in prior art
Accumulation of heat car.
