Description
Technical field
This utility model is related to phase-change material energy storage technical field, especially relate to a kind of for phase-change thermal storage type device
Plastic inner container.
Background technology
Phase-changing energy storage material refers to, during its thing phase change, to carry out energy exchange with external environment, thus reaching
To using energy and control the material of ambient temperature.Phase-change material absorbs heat when temperature is higher than transformation temperature and undergoes phase transition,
Store heat in phase transition process, and material temperature is not raising or raising less；When temperature is less than transformation temperature, occur inverse
To phase transformation, phase-change material recovers original thing phase, discharges heat in phase transition process.
The inner bag material of phase change material device common at present is metal, because inner bag inner surface is directly connect with phase-change material
Touch it is impossible to ensure the dependability of inner bag, consequently, it is possible to shortening the safe operating life of inner bag.Application No.
The Chinese utility model patent of CN201310525940.8 discloses a kind of phase change heat storage jacket type water tank, and this water tank includes having
The metal water storage liner of water-in and water-out structure and the lagging casing surrounding inner bag, the gallbladder wall of described inner bag is at least partially formed by interior
Wall and the metal sandwich structure of outer wall composition, described sandwich at least forms two mutually isolated chuck chambeies, one of them
For the heat accumulation chuck chamber of fill phase-change material, another heat exchange jacket chamber for having heat transferring medium import and export.Of the present utility model
Two-chamber sandwich can obtain maximum inner bag rigidity and volume, both prevented on the premise of using identical weight metal material
The only damage to inner bag, avoids producing space reduction heat exchange efficiency again, but inner bag inwall adopts metal material and direct and phase transformation
Heat accumulating contacts, and the index such as its dependability is further improved.
Utility model content
The purpose of this utility model is exactly to overcome the defect of above-mentioned prior art presence to provide one kind to be used for phase transformation
The plastic inner container of heat storage type device.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of plastic inner container for phase-change thermal storage type device, including inner bag body, this inner bag body is to contain phase transformation material
The plastic containers of the open topped of material, are also close to arrange rigid strutting piece in inner bag body outer surface.
Described inner bag body is polypropylene containers or polyethylene can.Polyethylene can be Low Density Polyethylene, highly dense
The degree heatproof such as polyethylene or linear low density polyethylene and the plastics not reacted with phase-change material.
Described inner bag body includes the ladle body of upper and lower opening, and the base being tightly connected with ladle body lower end.
Described ladle body is polypropylene or polyethylene with the material of base.
Described base and ladle body are tightly connected by thermofussion welding.
Described inner bag body is square, cylindrical or template.Or can be the shapes such as other polygons.
Described rigid strutting piece is made up of hard, rigid material, and the outer surface of its inner wall surface and inner bag body closely pastes
Close.
The outside wall surface of described inner bag body gradually tapers up to top from bottom, is also equipped with rigid strutting piece outer surface
Dismountable holding assembly；When not installing holding assembly, the internal diameter of rigid strutting piece is not less than the maximum outside diameter of inner bag body, embraces
When tight assembly is arranged on rigid strutting piece, the outside wall surface of the inner wall surface laminating inner bag body of rigid strutting piece.
Described holding assembly is anchor ear or bolt.
The angle of throat of the described outside wall surface of inner bag body is 5～10 °.
Described inner bag body bottom portion is provided with raised line, and the inner bottom surface of described rigid strutting piece is provided with is mated with raised line
Groove.The setting of raised line not only can facilitate the installation between inner bag body and rigid strutting piece to mate, simultaneously for there being rolling
Dynamic application places, raised line can effectively prevent the phase mutual friction between inner bag body and rigid strutting piece, it is to avoid due to interior
The problem that gallbladder body frictional dissipation is excessive and the inorganic phase-changing material of the inside is spilt.
Described hard, rigid material is metallic plate, metal rack, plastic plate or foamed board.
Because present inorganic phase-changing material is usually inorganic hydrated salt class, its advantage is that unit volume storage density is big,
Heat conductivity is relatively higher than organic phase change material, but inorganic hydrated salt class phase transformation material has certain Acidity of Aikalinity, to metal
Container has certain corrosivity, and life-time service reliability has hidden danger, thus affecting the service life of heat-storing device.Therefore,
This utility model adopts plastic inner container, and its inner bag body is made using plastic material, and these plastic materials have excellent corrosion resistant
Corrosion energy, will not be reacted with phase-change material, thus avoid phase-change material will not reveal from plastic inner container.Plastics simultaneously
Inner bag is the opened type structure of container of sealed bottom, can effectively ensure the atmospheric pressure state within phase change material device.And mould
Rigid strutting piece is posted it is ensured that inner bag body can bear the pressure of phase-change material in the outside of the inner bag body of material material,
Will not deform.
Compared with prior art, this utility model has advantages below：
(1) the inner bag body of plastic inner container of the present utility model is the opened type container of sealed bottom, internal filling phase transformation
Material, phase-change material is directly contacted with inner bag inner body wall, because plastics have excellent decay resistance, chemical stability
Good, therefore can extend the service life of inner bag.
(2) the inner bag body of plastics has higher rigidity and toughness, and mechanical strength is good, and ageing-resistant performance is good, and
It is glued with support member in inner bag body exterior, increased the ability of anti-deformation of inner bag body, ensure that phase-change thermal storage type device
Dependability.
(3) structure is simple, safe and reliable, solves the defect of existing phase-change thermal storage type device inner bag, substantially increases phase
Become the reliability of heat-storing device, reduce the production cost of inner bag simultaneously, extend its service life.
(4) convertibility is strong：Non-yielding prop assembly is reusable, when inner bag body is damaged, can by its from
Extract out in rigid strutting piece, change, thus avoiding the high cost problem all changing whole plastic inner container.
(5) because plastics have excellent decay resistance, chemical stability is good, and does not occur with inorganic phase-changing material
Chemical reaction, safe and reliable, substantially increase the reliability of phase change material device.In addition, plastic inner container is than metal inner tube more
Economy, reduces the production cost of inner bag.
