Abstract
Description
図1は、本発明の実施の形態にかかる頭部冷却装置1の概略構成を示すブロック図である。
図2は、図1に示す頭部冷却用枕2の概略構成を示す平面図である。図3は、図2のE部の断面を示す断面図である。図4は、図2のF部の断面を示す断面図である。以下の説明では、互いに直交する3方向のそれぞれをX方向、Y方向およびZ方向とし、X方向を左右方向、Y方向を前後方向、Z方向を上下方向とする。また、X1方向側を「右」側、X2方向側を「左」側、Y1方向側を「奥」側、Y2方向側を「手前」側、Z1方向側を「上」側、Z2方向側を「下」側とする。なお、図3では、前後方向と上下方向とから構成される平面に平行なE部の断面が図示され、図4では、左右方向と上下方向とから構成される平面に平行なF部の断面が図示されている。
以上説明したように、本形態では、枕本体11の内部に形成される流路13を通過する冷媒によって枕2に支持される頭部が冷却される。そのため、本形態では、1回の熱交換で頭部を冷却することができ、その結果、頭部の冷却効率を高めることが可能になる。
上述した形態では、頭部が当接する枕本体11の上面部11fの下面にベース部12aの上面が当接するように、スペーサ12が配置されているが、上面部11fの下面に支持突起12cおよび仕切部12bが当接し、枕本体11の下面部11gの上面にベース部12aが当接するように、スペーサ12が配置されても良い。前者の場合には、ベース部12aを介して支持突起12cに頭部が支持されるため、ベース部12aを介さずに支持突起12cに頭部が支持される場合と比較して、枕2への頭部の載せ心地が良くなる。一方、後者の場合には、枕本体11の上面部11fの下面に冷媒が直接、接触するため、頭部の冷却効果を高めることが可能になる。
