Description
Technical field
The present invention relates to a kind of Teat pump boiler inner container and preparation method thereof, is the improvement to existing Teat pump boiler inner container structure and preparation method thereof, belongs to the heater applied technical field.
Background technology
Teat pump boiler is no longer strange by people, it be by compressor, condenser, choke valve, evaporimeter by conduit by being formed by connecting in turn, its operation principle is: cold-producing medium comes out from compressor, forms high temperature and high pressure gas, is introduced the condenser that places the water heater storage tank by conduit; After the water heat exchange in condenser and the water heater storage tank, high temperature and high pressure gas just becomes cryogenic high pressure liquid; Introduce the choke valve decompression through conduit again, become low-pressure liquid, promptly become low-temp low-pressure liquid; Low-temp low-pressure liquid enters evaporator evaporation and becomes gaseous state; And then will become the cold-producing medium of gaseous state to introduce compressor by evaporator evaporation to become high temperature and high pressure gas once more by being linked to conduit between evaporimeter and the compressor, circulation is heated the water in the water heater storage tank by condenser in turn.The said system custom is called the heat pump of Teat pump boiler.
Have Teat pump boiler inner container in the above mentioned water heater storage tank, condenser is housed inside in the Teat pump boiler inner container, and heat exchange is carried out in inner bag.
At present, for the inner-tube structure of Teat pump boiler mainly by following several: a kind of is pure stainless steel inner container, it be by two ends have respectively spherical crown surface and each other the cylindrical body butt welding of equal diameters constitute, be shaped on the water-in and water-out interface in advance on the spherical crown surface of one of them cylindrical body, the heater interface is the heating element heater interface, and the spherical crown surface of another cylindrical body is a complete closed.Thereby the inner bag of this structure, with two cylindrical body butt welding causes seriously reducing at the chromium content that contains at weld seam position owing to need welding, and stainless corrosion resistance shows comparatively fragile in the welding position, need not use through long-term, and leaking just appears in inner bag; Second kind is the rotational moulding inner bag, in the rotational moulding again of the inner bag surface of metal material, constitutes composite construction, yet the rotational moulding layer very easily and produce shelling between the metal level.And the inner bag of rotational moulding structure for heater (also can claim heat(ing) coil) is installed in the inner bag, must constitute a bigger flange, during by the dress heater, with the rubber seal sealing, facts have proved, this structure also very easily produces and leaks; The third is an enamel inner container, and the inner bag of this structure has excellent corrosion resistance, still, in process of production must be careful, in order to avoid damage enamel coating.Yet although double cautious, the phenomenon that causes enamel layer to strip off in the production assembling process can't be avoided all the time, in case fall porcelain, inner bag will corrode and percolating water at short notice.In addition, also have the flange seal problem that resembles the rotational moulding inner bag equally.
The applicant once retrieved, and had searched Chinese patent literature A) .CN1381699A, B) .CN142-1657A, C) .1147398C, in one's power technical scheme all proposes at the inner bag of electrical heating water heater in these documents.Document A). introduced a kind of internal plastic container of electric water heater, form by at least two plastic shaping housing butt joints, be distributed with the connecting plate and the joint pin of some moulding in each shell inner surface, all connecting plates on the housing that connects and joint pin are corresponding one by one and interconnect.Though have the alleged workability of patent, an advantage (the summary of the invention hurdle that specification is first page) such as cost is low, shaping efficiency is high, anticorrosion and heat insulation capacity is strong, there is obvious deficiency in the inner bag of this structure.The one, in order to satisfy requirement of strength, there are numerous joint pins and connecting plate at the inwall of inner bag, thereby occupied the dischargeable capacity of inner bag unreasonably; The 2nd, housing is provided with sealing ring or other encapsulant (second page of embodiment 1 of specification) to after connecting in junctions such as housing outsides, therefore reveals probability than higher; The 3rd, resistance to ag(e)ing is unsatisfactory.
Document B). recommended water heater inner tube of plastic structure and manufacture method thereof, said in a sense, the water heater liner of this kind structure can embody its series of advantages of enumerating in the 5th page the 3rd section in specification, but also exists following three place's drawbacks.The one, the intensity of inner bag can not rationally be ensured, perhaps the patent scheme has been recognized strength problem, mentioned the metal damascene structure that is provided with wire netting or bonding jumper and other type in the inner bag plastic construction for the 5th page at the claim specification, yet so instruction can make and make become trouble, complexity more, and especially form, the structure for wire netting, bonding jumper and other metal inlay do not give enlightenment.Because, if wire netting, bonding jumper and other metal inlay are not constituted a complete and comparatively firm structural system, it is seemingly very difficult to obtain integral intensity with roller coating so entirely, and for example fruit only is that the mode with place mat such as wire netting is embodied, its intensity more can not embody so, because the global shape of inner bag is columnar; The 2nd, the resulting inner-tube structure of this patent, must carry out extra reinforcement to entery and delivery port, alleged as specification, need entery and delivery port is provided with polyethylene pipe or PA tube or composited aluminum and plastic decking or the like, need in addition other fabrication hole opening part coating plastic, thereby can cause the increase of tediously long, the mould of technology; The 3rd, the controlling element in the process procedure is many, is difficult to the support control.
Document C). internal container of steel-plastics composite water heater and production method thereof are provided, have comprised steel shell, internal heater, feature is to be lined with a plastic lining in steel shell, and steel shell (courage body) is made of cylindrical housings and end cap combination.The shortcoming that this patent structure exists, with cylindrical housings and end cap welding, can cause the chromium content loss of aforesaid welding position, the corrosion resistant persistence between commissure or title cylindrical housings and the end cap is poor, cause seepage, because welding is carried out behind the plastic lining lining; Durable bond effectively between the interior type of plastic lining and steel shelling can occur, thereby can't be come the interior type of steel is effectively protected by lining, and cylindrical housings and end cap welding portion subject to corrosion and the generation seepage; Complex process, for example for fear of undermine lining when welding, need are provided with thermal insulation layer at the ring-type weld seam position of the junction of the end cap of columniform steel casing and steel, or the like.
