Technical field
The utility model relates to a kind of accumulation of heat and heating plant, relates in particular to a kind of wire netting first-harmonic line tubular type phase transition heat accumulation unit, belongs to the heat storage technology field.
Background technology
Along with a large amount of consumption of constant development of economy and the energy, energy-conservation topic has become the focus that the whole world is paid close attention to.Nowadays, solar energy, wind energy, etc. the utilization of regenerative resource and industrial exhaust heat, used heat become the emphasis of various countries' research, yet these energy all exist discontinuity and instable characteristics, therefore, it is particularly important that the research of energy storage technologies just seems.The thermal storage and energy accumulation technology is a kind of of energy storage technologies, can be used for solving the contradiction of heat energy supply and demand mismatch, is the important technology that improves efficiency of energy utilization and environmental protection.At present, some device and equipment that utilize the thermal storage and energy accumulation technology to carry out heat supply occur in succession, and can satisfy the demand of corresponding energy storage and heat supply.Existing regenerative apparatus major part is set to tubular structure, flows to finish accumulation of heat, the overall process of heat release by hot cold water in the heat exchanger tube.But, problem such as what heat exchanger tube in most regenerative apparatuses adopted is isodiametric heat exchanger tube, and it exists heat exchange area little, and heat transfer efficiency is poor, and phase transformation is discontinuous, and heat storage capacity is low.
Summary of the invention
It is a kind of simple in structure that the utility model is intended to provide, and the heat-storing material storage is many, and heat exchange area is big, heat transfer efficiency height, the wire netting first-harmonic line tubular type phase transition heat accumulation unit that heat storage capacity is strong.
The utility model is achieved through the following technical solutions:
A kind of wire netting first-harmonic line tubular type phase transition heat accumulation unit, this device comprises shell and accumulation of heat casing, be provided with the multilayer heat exchanger tube in the described accumulation of heat casing, dispense tube and fluid collecting pipe, the fluid inlet of accumulation of heat casing links to each other with an end of dispense tube, the other end of dispense tube links to each other with the import of each layer heat exchanger tube, the outlet of each layer heat exchanger tube is connected with an end of fluid collecting pipe, the other end of fluid collecting pipe is discharged phase transition heat accumulation unit by fluid issuing with fluid, in with one deck, heat exchanger tube is many rows and arranges, each is arranged heat exchanger tube and is communicated with by elbow, be wound with wire, other vacant local filling heat accumulating phase change material in the accumulation of heat casing between adjacent two row's heat exchanger tubes.
In the utility model, the wire that twines between adjacent two row's heat exchanger tubes is network structure.
In the utility model accumulation of heat casing, tight wrong discharging is put between each layer heat exchanger tube.
The utility model heat exchanger tube is bellows, is made of node and trough, and in one deck, the node of adjacent two row's bellowss is corresponding with trough to be tight wrong row's setting.
The utility model heat accumulating phase change material is paraffin, crystalline hydrate salt or fatty acid phase-change material.
In order to reduce energy loss, laid heat-insulation layer at the outer wall of accumulation of heat casing.
The utility model hot fluid and cold fluid share same fluid inlet and same fluid issuing.
Described phase transition heat accumulation unit is determined device size according to the size of amount of stored heat, increases and decreases the length of bellows according to the requirement of rate of heat release.
When hot water enters bellows in the regenerative apparatus, heating bellows wall, phase-change material in the accumulation of heat casing under a certain temperature by the solid-state liquid state that becomes, the latent heat that makes heat energy be converted into heat-storing material stores, when needs heat energy, make cold water pass through bellows in the phase transition heat accumulation unit, when cold water during by bellows, water is heated by bellows by heat-conducting medium, reach user's the heat request of using.After heat-storing material was emitted the part heat, the liquid near bellows in the accumulation of heat casing at first solidified, and along with the carrying out of heat release, liquid phase and solid phase interface are gradually away from the bellows wall, and final, heat-storing material is all become solid-state by liquid state.
The beneficial effects of the utility model are:
In the utility model, heat exchanger tube is bellows, is made of node and trough, and in one deck, the node of adjacent two row's bellowss is corresponding with trough to be tight wrong row and to arrange, and adjacent two arrange the wire that twines between the heat exchanger tubes is network structure.This structure makes heat accumulation and exothermal efficiency effectively improve, and fluid can reduce 30% through heat accumulation and the heat release time of heat exchanger tube.
In the utility model, except tube fluid generation turbulent flow with the augmentation of heat transfer, manage between outer node and the straight tube, the distance between node and the node oblique line remains on a relative thinner distance, and these distances multi-faceted be space layout.Simultaneously, twine wire between adjacent two row's bellowss and form the space network structure, help phase-change material that even phase transformation and heat conduction take place like this.Simultaneously because variant with straight tube position unofficial biography thermal effect outside the node position, cause the different parts phase-change material temperature variant, the difference at position, this space and the different temperatures data of the different parts natural convection effect during with further reinforced transformation material liquid stateization.Simultaneously also can be multi-faceted heat conduction between during reinforced transformation material solid state.Thereby overcome the low problem of its thermal conductivity factor.
The utility model is simple in structure, heat exchange area is big, and fluid can form turbulent flow when flowing in bellows, improved heat transfer efficiency, heat absorption and heat release speed are fast, and the heat-storing material capacity is big, has improved heat storage capacity, this phase transition heat accumulation unit can take full advantage of solar energy, and industrial exhaust heat carries out high efficiency Waste Heat Recovery utilization.
