Cooling mat

Abstract

Disclosed is a cooling mat in which an effective cooling effect can be promoted by a simple structure free from separate manipulation or external power sources, capable of increasing reliability in operation and portability, the cooling mat including: a plurality of cooling pads filled therein with a phase change material; an upper cover coupled to the cooling pad, lengthwise formed with a plurality of openings and exposing an upper surface of the cooling pad through the openings; a bottom cover coupled to the upper cover at an edge portion; and a folding unit formed between the openings of the upper cover to provide a bending flexibility.

1 . A cooling mat comprising:
 a plurality of cooling pads filled therein with a phase change material;   an upper cover coupled to the plurality of cooling pads, lengthwise formed with a plurality of openings and exposing an upper surface of the plurality of cooling pads through the opening;   a bottom cover coupled to the upper cover and an edge portion; and   a folding unit formed between the opening of the upper cover to provide a bending flexibility.   
     
     
         2 . The cooling mat of  claim 1  wherein the cooling pad includes the upper cover, the bottom cover and the phase change material that is filled between the upper and bottom covers, wherein the upper and bottom covers are sealed at a seam therebetween by welding using high frequency. 
     
     
         3 . The cooling mat of  claim 2 , wherein the cooling pad is formed with a plurality of dotted pattern adhesive units in which the upper cover and the bottom cover are sealed. 
     
     
         4 . The cooling mat of  claim 3 , wherein the dotted pattern at the adjacent adhesive units takes the shape of a zigzag. 
     
     
         5 . The cooling mat of  claim 2 , wherein the cooling pad is formed with a plurality of adhesive units in which an upper cover and a bottom cover are adhered in a line shape, and a plurality of sealing spaces is formed between each adhesive unit. 
     
     
         6 . The cooling mat of  claim 5 , wherein the adhesive unit is formed with a plurality of horizontal and vertical lines, each line formed at an equidistance, and a plurality of square sealing spaces is formed by the adhesive units. 
     
     
         7 . The cooling mat of  claim 1 , further comprising a cushion unit formed between a bottom surface of the cooling pad and an upper surface of the bottom cover and filled with a cushioning material. 
     
     
         8 . The cooling mat of  claim 2 , further comprising a cushion unit formed between a bottom surface of the cooling pad and an upper surface of the bottom cover and filled with a cushioning material. 
     
     
         9 . The cooling mat of  claim 3 , further comprising a cushion unit formed between a bottom surface of the cooling pad and an upper surface of the bottom cover and filled with a cushioning material. 
     
     
         10 . The cooling mat of  claim 4 , further comprising a cushion unit formed between a bottom surface of the cooling pad and an upper surface of the bottom cover and filled with a cushioning material. 
     
     
         11 . The cooling mat of  claim 5 , further comprising a cushion unit formed between a bottom surface of the cooling pad and an upper surface of the bottom cover and filled with a cushioning material. 
     
     
         12 . The cooling mat of  claim 6 , further comprising a cushion unit formed between a bottom surface of the cooling pad and an upper surface of the bottom cover and filled with a cushioning material. 
     
     
         13 . The cooling mat of  claim 1 , further comprising a plurality of slip prevention lugs formed at a bottom surface of the bottom cover with a frictional material. 
     
     
         14 . The cooling mat of  claim 2 , further comprising a plurality of slip prevention lugs formed at a bottom surface of the bottom cover with a frictional material. 
     
     
         15 . The cooling mat of  claim 3 , further comprising a plurality of slip prevention lugs formed at a bottom surface of the bottom cover with a frictional material. 
     
     
         16 . The cooling mat of  claim 4 , further comprising a plurality of slip prevention lugs formed at a bottom surface of the bottom cover with a frictional material. 
     
     
         17 . The cooling mat of  claim 5 , further comprising a plurality of slip prevention lugs formed at a bottom surface of the bottom cover with a frictional material. 
     
     
         18 . The cooling mat of  claim 6 , further comprising a plurality of slip prevention lugs formed at a bottom surface of the bottom cover with a frictional material.
