Apparatus for filling heat storage material

Abstract

An apparatus for filling a heat storage material in a heat storage system for thermal energy delivery business is provided, wherein the heat storage system stores waste heat and is then moved a location where the heat is to be used, to dissipate the heat. According to the apparatus for filling a heat storage material, an accurate and uniform amount of a phase change material may be conveniently filled in the heat storage system while maintaining a liquid state of the heat storage material by melting the phase change material.

What is claimed is: 
     
         1 . An apparatus for filling a heat storage material, the apparatus being formed in a form of a container for storing heat by using a thermal energy delivery method, wherein the heat storage material is filled in a heat storage unit having an injection inlet formed in an upper portion of the heat storage unit, the apparatus comprising:
 a heating case comprising a filling chamber having an opened upper portion, an inlet through which hot water is supplied to the filling chamber, and an outlet formed in the filling chamber, wherein the hot water that has flown into the filling chamber is discharged through the outlet;   a holding frame comprising a holding portion on which the heat storage unit is held, wherein the holding frame enters the upper portion of the heating case to be seated in the filling chamber of the heating case;   a cover plate comprising a filling hole communicating with the injection inlet of the heat storage unit so as to fill the heat storage material through the injection inlet of the heat storage unit, wherein the cover plate is coupled to the holding frame; and   a gap member disposed between the holding frame and the cover plate and installed on one of the holding frame and the cover plate, such that the cover plate is coupled to the holding frame while maintaining a distance with respect to the holding frame,   wherein the holding portion of the holding frame comprises a unit guide having a shape corresponding to a lower surface of the heat storage unit such that a position of the heat storage unit with respect to the cover plate is aligned.   
     
     
         2 . The apparatus of  claim 1 , wherein a coupling hole, through which a bolt coupling the heat storage unit held on the holding portion of the holding frame and the cover plate to each other passes through, is formed in the cover plate. 
     
     
         3 . The apparatus of  claim 1 , wherein the inlet of the heating case is arranged in a lower portion of the filing chamber, and the outlet of the heating case is arranged in an upper portion of the filing chamber. 
     
     
         4 . The apparatus of  claim 3 , further comprising a distribution member installed in the filling chamber and comprising a plurality of distribution holes, through which the hot water flowing through the inlet is distributed into the filling chamber, and a distribution flow passage connecting the plurality of distribution holes and the inlet of the heating case. 
     
     
         5 . The apparatus of  claim 4 , wherein an inner diameter of the plurality of distribution holes of the distribution member increases away from the inlet of the filling chamber. 
     
     
         6 . The apparatus of  claim 1 , further comprising a checking member inserted into the heat storage unit through the filling hole of the cover plate to check a level of filling of the heat storage material. 
     
     
         7 . The apparatus of  claim 6 , wherein a measurement is marked on the checking member in a length direction.
