Abstract
The utility model discloses a kind of fin heat exchange structure, the accumulation of heat being filled with phase-change material comprising heat exchange layer and be connected with heat exchange layer or exothermic layer, it is characterized in that: in described accumulation of heat or exothermic layer, interval is provided with fin, one end of this fin is fixedly connected with described heat exchange layer, has a heat-insulation layer in the arranged outside of described accumulation of heat or exothermic layer.Compare for prior art, the utility model phase-change material flows in space between the fins, homogeneous temperature transfers heat to the heat exchange layer of bottom rapidly by fin, temperature also can be directly passed to heat exchange layer by the phase-change material near bottom, thus externally carries out heat exchange.The objects such as it is effective that the utility model achieves energy storage, and heat transfer is evenly quick, and heat exchange efficiency is high.
Description
Technical field
The utility model is related to the heat accumulation of phase-change material under high and low temperature state, stores up technical field that is cold and that conducted heat by fin reinforcement.
Background technology
In energy utilization system, ubiquity the problems such as energy supply is intermittent, stability is low, becomes one of key factor of restriction energy utilization rate raising.Energy storage technology is one of important technical addressed these problems, and can improve overall energy utilization rate.Phase change energy storage technology because having chemistry and good mechanical stability, the advantage such as security is high, thermal storage density is large, heat-accumulating process is similar to constant temperature process and very welcome in these fields.But the structure of common storage phase-change material, heat conductivility is poor, and thermal conductivity factor is low, and heat exchange is slow, externally can not conduct heat uniformly rapidly the short time, thus causes the efficiency of heat accumulation and Chu Leng low.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide the heat exchange structure that a kind of structure is simple, with low cost, easy to operate, heat conductivility is high, heat exchange is fast, efficiency is high.This heat exchange structure can carry out external heat exchange sooner more fully, thus improves the efficiency of heat transfer.
The utility model for achieving the above object, adopt following technical scheme: a kind of fin heat exchange structure, the accumulation of heat being filled with phase-change material comprising heat exchange layer and be connected with heat exchange layer or exothermic layer, it is characterized in that: in described accumulation of heat or exothermic layer, interval is provided with fin, one end of this fin is fixedly connected with described heat exchange layer, has a heat-insulation layer in the arranged outside of described accumulation of heat or exothermic layer.
Described fin is arranged in described heat exchange layer uniformly.
Described fin is cylindricality, is provided with heat conduction gear piece uniformly in the outer surface elongatedness direction of described cylindricality.
The phase-change material stated is organic material or inorganic material.
Described organic material is paraffin class, aliphatic acid and higher aliphatic hydrocarbon, alcohol, carboxylic acid or salt.
Described inorganic material is eutectic, crystalline hydrate salt, metal or alloy.
The utility model heat exchange structure arranges the fin stretching into accumulation of heat or exothermic layer in heat exchange layer.The setting of fin, not only expands the heat exchange area of heat exchange layer, improves the heat conduction speed of heat exchange layer, and increases the contact area of heat exchange layer and phase-change material, more improves case in accumulation of heat or exothermic layer and becomes the efficiency of material accumulation of heat or heat release.Compared with prior art, it is simple that the utility model has structure, and energy storage is effective, good heat conductivity, and heat transfer is fast even and efficiency is high.
The utility model only adopts a heat-transfer surface to be more use under appropriate circumstances targetedly, and heat exchange is simultaneously more controlled; The existence of fin improves every heat transfer property of phase-change material.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is that bottom the utility model, top view arranged by fin.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of fin heat exchange structure of filling phase-change material as shown in Figure 1, primarily of heat exchange layer 1, heat-insulation layer 2, the phase-change material 4 flowed in fin 3 and between the fins space forms.Wherein the shape of fin 3 is cylindricality, is cylindrical in the present embodiment, columniform outer peripheral face is provided with heat conduction gear piece uniformly, and interval, heat conduction gear piece elongatedness direction is arranged.
Be wrapped in heat-insulation layer in the surrounding of structure and top, heat exchange layer is placed in bottom.The fin of heat exchange structure inside directly contacts with bottom heat exchange layer.Phase-change material can transfer heat to heat exchange layer by fin, or near bottom can directly and heat exchange layer contact heat-exchanging.
When using the utility model, by heat exchange layer and external heat-exchanging object contact, cold energy or thermal energy are passed through heat exchange layer by external object, a part of direct and bottom phase-change material heat exchange, another part by fin rapidly and pass to phase-change material uniformly, this part energy drawn by phase-change material, carries out phase-change accumulation energy, until reach maximum energy storage capacity and stop.
