Description
Technical Field
The utility model relates to a heat-retaining technical field specifically is a heat storage core.
Background
With the development of economy, energy conservation has become a necessity and social consensus. Energy is in many cases not yet available in a rational manner, resulting in considerable waste, which requires devices for temporarily storing the energy and releasing it for use when needed. In recent decades, a great deal of facts prove that the phase change material has a good development prospect in the aspect of energy storage. Especially in the fields of solar thermoelectric conversion, industrial residual electricity utilization and recovery, electric power peak regulation, building energy conservation and greenhouse cultivation. In response to the above needs, phase change energy storage is increasingly gaining attention. At present, the main phase-change materials are more applied by fluoride, chloride and carbonate of alkali metal or alkaline earth metal.
However, most of the existing phase change energy storage materials have low storage speed, low efficiency and high temperature requirement, and the storage quantity is greatly influenced by the materials and is difficult to break through, so the application in individual aspects is greatly limited.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a heat storage core to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
a heat storage core comprising a heat storage core body; the heat storage core body comprises a metal shell and a paraffin expansion graphite phase-change composite material layer, the paraffin expansion graphite phase-change composite material layer is filled in the inner side of the metal shell, and two ends of the metal shell are hermetically connected with sealing covers.
As a further aspect of the present invention: the metal shell is welded with the sealing cover.
As a further aspect of the present invention: the metal shell is made of copper materials.
As a further aspect of the present invention: the metal shell is made of iron or aluminum materials.
As a further aspect of the present invention: the paraffin expanded graphite phase-change composite material layer is a cylindrical body, a strip-shaped body or a polygonal body.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model relates to a novelty, all metal casing sets up, still makes heat conduction area strengthen except hard protection, deposits the speed of heat energy and accelerates, and paraffin inflation graphite phase transition combined material layer seals the back by the phase transition material compression, has increaseed the volume of heat-retaining material to improve storage capacity greatly, it has effectively solved current heat storage core storage speed slow, the lower problem of efficiency.
Drawings
Fig. 1 is a schematic structural diagram of a thermal storage core.
In the figure: 1-sealing cover, 2-metal shell and 3-paraffin expanded graphite phase-change composite material layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a heat storage core includes a heat storage core body; the heat storage core body comprises a metal shell 2 and a paraffin expansion graphite phase change composite material layer 3, the paraffin expansion graphite phase change composite material layer 3 is filled on the inner side of the metal shell 2, and the two ends of the metal shell 2 are hermetically connected with the sealing covers 1, the paraffin expanded graphite phase-change composite material is compressed by the shell according to the proportion of 1/2-1/4 and then is sealed in the metal shell 2, the paraffin phase is changed from solid to liquid, the heat energy is rapidly stored in the core in a large amount, the process is that 500 g of composite material can store 180-190 kilocalories of heat which is 3-3.5 times of that of water, then the heat energy can be released through the release of the metal surface or other contact modes, the paraffin wax reversely changes the phase to release the heat energy, therefore, the purposes of storing heat energy and releasing heat energy in a delayed manner are achieved, and the heat energy storage device can be applied to the fields of indoor and outdoor heating, electric power peak regulation and the like.
In the specific implementation process of the present invention, the fixing manner of the metal shell 2 and the sealing cover 1 includes but is not limited to welding.
In the specific implementation process of the present invention, the metal casing 2 can be made of copper material.
In the specific implementation process of the present invention, another embodiment can be provided, specifically, the metal housing 2 can be made of iron or aluminum material.
Preferably, the paraffin-expanded graphite phase-change composite material layer 3 is compressed into a cylindrical body, a strip-shaped body or a polygonal body.
It needs to explain very much, sealed lid is prior art's application in this application, and all metal casing sets up, and except hard protection still make heat conduction area increase, the speed of depositing heat energy accelerates, and paraffin inflation graphite phase transition composite material layer is by the phase transition material compression closed back, has increaseed the volume of heat-retaining material to improve the storage capacity greatly and be the innovation point of this application, it has effectively solved current heat storage core storage speed slowly, the lower problem of efficiency.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
