The kanji 凍 is a phono-semantic compound (形声文字, けいせいもじ). The semantic component is 冫 (こおり, "ice"), which provides the meaning related to cold and freezing. The phonetic component is 東 (とう, "east"), which is included to hint at the sound of the character (in this case, トウ tou). The original meaning of 東 is "to bind" (to tie or wrap) and eventually "east" evolved from this meaning. The combination of 冫 and 東 conveys the idea of something being bound or solidified by the cold, resulting in freezing.
