Abstract
The utility model discloses a foamed metal heat transfer structure, including the heat transfer layer and with the energy storage layer of heat transfer layer contact, its characterized in that: the energy storage layer is for filling the foamed metal layer that there is phase change material be provided with the heat preservation outside the foamed metal layer, the foam metal framework material on foamed metal layer is that 2-3mm in the aperture, porosity are 70-95% through -hole type cu. Foam metal framework selects the through -hole foamed metal cu that the heat conductivility is high, the porosity is high, specific surface is big. Phase change material flows in the through -hole of foamed metal, and the heat transfer is externally carried out on the even rapid bottom heat transfer layer of passing through of temperature. The utility model discloses an energy storage is effectual, and is efficient, the purpose such as fast of conducting heat.
Description
Technical field
The utility model relates to the heat accumulation of phase-change material under high and low temperature state, stores up cold and technical field of heat transfer, and specifically a kind of heat of carrying out heat exchange based on phase-change material changes structure.
Background technology
The energy is the grand strategy goods and materials of national economy and social development, is the basis of modern economy social development.But in fields such as air conditioner refrigerating, building energy conservation and utilization of new energy resources, the problems such as ubiquity energy supply is intermittent, stability is low.Energy storage technology is one of important technical addressed these problems.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 heat exchange is slow, externally can not conduct heat uniformly rapidly the short time, 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, adopts following technical scheme:
A kind of foam metal heat exchange structure, the accumulation of energy layer comprising heat exchange layer and contact with heat exchange layer, is characterized in that: described accumulation of energy layer, for being filled with the foam metal layer of phase-change material, is outside equipped with heat-insulation layer at described foam metal layer.
The through hole type Cu that the foam metal framework material of described foam metal layer is aperture 2 ~ 3mm, porosity is 70 ~ 95%.
The cross sectional shape of described foam metal layer is circular or polygon.
Described phase-change material 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 comprises eutectic, crystalline hydrate salt, metal or alloy.
Described heat exchange layer is that heat-conducting effect is excellent, the material of energy uniform heat exchange.
Described heat-insulation layer adopts conventional heat-preservation cotton.
The utility model heat exchange structure adopts foam metal, and fills phase-change material in the through hole of foam metal.The through hole type Cu that foam metal adopts aperture 2 ~ 3mm, porosity is 70 ~ 95%, especially when porosity is 95%, the maximized heat exchange efficiency that improve foam metal under the prerequisite ensureing manufacturing cost.Thus utilize the foam metal of good heat conductivity to realize conducting heat fast uniformly, and absorb compared with material or release heat energy, greatly improve the heat storage performance of phase-change material, both improve heat exchange amount, turn improved heat exchange rate.
Compared with prior art, advantage of the present utility model is that structure is simple, and easy to operate, energy storage is effective, good heat conductivity, and heat transfer is fast even and efficiency is high.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of foam metal heat exchange structure of filling phase-change material as shown in Figure 1, comprises heat exchange layer 1, heat-insulation layer 2 and accumulation of energy layer.Accumulation of energy layer is made up of foam metal skeleton 3 and the phase-change material 4 that flows in its through hole, and the cross sectional shape of metallic framework 3 is circular or polygon, and in the present embodiment, cross sectional shape is rectangle.
In production technology, foam metal skeleton is supported as total, in its through hole, add phase-change material.Be wrapped in heat-insulation layer in the surrounding of foam metal skeleton and top, heat exchange layer is placed in bottom.
When using the utility model, by heat exchange layer and external heat-exchanging object contact, external object by cold energy or thermal energy by heat exchange layer and foam metal, rapidly and the phase-change material passed to uniformly in through hole, this part energy drawn by phase-change material, carry out phase-change accumulation energy, until reach maximum energy storage capacity and stop.
The utility model only adopts a heat-transfer surface to be more use under appropriate circumstances targetedly, and heat exchange is simultaneously more controlled; Foam metal skeleton improves every heat transfer property of phase-change material.
