Thermal Container Insulated With Phase Change Material

Abstract

A thermal container insulated with phase change material comprising a plurality of panels to form a body with a plurality of sides, a bottom and a lid, wherein each panel further comprises: a lining board, a phase change cold storage board, an insulation board; and a skin board. The phase change cold storage board further comprises an array of openings filled with solid-solid phase change material. The thermal container can maximize its storage capacity without compromising any volume for ice. It can maintain an accurate temperature range suitable for transportation. The container is reinforced at various locations to improve stability and structural integrity.

         9 . A thermal container insulated with phase change material comprising a plurality of panels to form a body with a plurality of sides, a bottom and a lid, wherein each panel, in an order from inside to outside, further comprises:
 a lining board,   a phase change cold storage board,   an insulation board; and   a skin board.   
     
     
         10 . A thermal container insulated with phase change material of  claim 9 , wherein the insulation board provides support as an anchoring structure for the phase change cold storage board and the skin board, and the lining board is further fixed onto the phase change cold storage board. 
     
     
         11 . A thermal container insulated with phase change material of  claim 9 , wherein the phase change cold storage board further comprising:
 a hollow board which comprises a grid of abutting partitions of a preset geometric shape organized in an array both lengthwise and widthwise; and   a solid-solid phase change material filled into openings reserved by the grid of abutting partitions.   
     
     
         12 . A thermal container insulated with phase change material of  claim 9  is reinforced by:
 applying sealant along all edges where any one inner surface meets another; 
 applying sidebars around all outside edges; 
 applying corner wrappings to all outside base corners; 
 applying a frame around edges where the thermal container opens; and 
 fastening the sidebars, corner wrappings and the frame with rivets. 
 
     
     
         13 . A thermal container insulated with phase change material of  claim 9 , wherein the insulation board further comprises clamping grooves around its bottom edges, and can be snapped into position with interlocking protrusions and indentations located at front and back ends where one edge meets another. 
     
     
         14 . A thermal container insulated with phase change material of  claim 9 , wherein inner edges along the container's opening are sunken to accommodate corresponding edges from the cover and sealing strips all around. 
     
     
         15 . A thermal container insulated with phase change material of  claim 9 , wherein the insulation boards further comprises extruded polystyrene, EPS, and EPP boards. 
     
     
         16 . A thermal container insulated with phase change material of  claim 9 , wherein the lining board is bonded to the phase change cold storage board.
