Description
Technical Field
The utility model belongs to the technical field of the phase transition heat-retaining, especially, relate to a novel water conservancy diversion baffle phase transition heat-retaining unit structure.
Background
The traditional phase-change heat storage unit consists of an outer structure of the heat storage unit, a phase-change material filling layer and an inner sleeve (as shown in figure 1), or the structure form of a horizontal partition plate is added (as shown in figure 2), and the traditional phase-change heat storage unit has the technical defects that the phase-change material in the phase-change heat storage unit is uneven in heating distribution, poor in heat exchange performance and long in melting time of the phase-change material.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel water conservancy diversion baffle phase transition heat-retaining unit structure can obviously weaken the inhomogeneous phenomenon of phase change material distribution of being heated in the phase transition heat-retaining unit, makes the heat transfer performance of phase transition heat-retaining unit promote by a wide margin, and phase change material melts the time and shortens by a wide margin.
The utility model provides a novel water conservancy diversion baffle phase transition heat-retaining unit structure, including heat-retaining unit outer structure, phase change material filling layer, water conservancy diversion baffle and interior sleeve pipe, the water conservancy diversion baffle sets up along the slope of heating working medium flow direction, the water conservancy diversion baffle is the acute angle with the contained angle of heat-retaining unit outer structure inner wall.
Furthermore, the included angle between the flow guide partition plate and the inner wall of the outer structure of the heat storage unit is 30 degrees.
By means of the scheme, the phase change material in the phase change heat storage unit can be obviously weakened to be unevenly distributed when being heated through the novel flow guide partition plate phase change heat storage unit structure, so that the heat exchange performance of the phase change heat storage unit is greatly improved, and the melting time of the phase change material is greatly shortened.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 3, the embodiment provides a novel diversion barrier phase-change heat storage unit structure, which includes a heat storage unit outer structure 31, a phase-change material filling layer 32, a diversion barrier 34 and an inner sleeve 33, wherein the diversion barrier 34 is obliquely arranged along a flowing direction of a heating working medium, and an included angle between the diversion barrier 34 and an inner wall of the heat storage unit outer structure 31 is an acute angle.
In the embodiment, the angle between the baffle 34 and the inner wall of the heat storage unit 31 is 30 degrees.
The inner sleeve 33 of the novel baffle plate phase-change heat storage unit structure conducts heat to the phase-change material filling layer 32 (such as fused salt, paraffin and the like) through a heat transfer medium (such as high-temperature water or steam and the like) through the baffle plate 34, and the phase-change material stores energy through phase-change latent heat. The structure is additionally provided with the flow guide partition plate 34 on the basis of the common phase change sleeve, when the flow guide partition plate 34 increases the heat exchange between the phase change material and the heat transfer medium through heat conduction, the heat convection inside the phase change material is promoted, the phenomenon that the phase change material in the phase change heat storage unit is unevenly distributed when being heated can be obviously weakened, the heat exchange performance of the phase change heat storage unit is greatly improved, and the melting time of the phase change material is greatly shortened.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
