A　new　kind　of　experimental　equipment　has　been　established　to　prepare　for　making　a　study　on　the　heat　transfer　of　jet　impingement　when　quaternary　mixed　nitrate　will　be　regarded　as　working　fluid.　In　order　to　verify　the　validation　of　experimental　equipment　and　method,　a　experimental　study　on　the　heat　transfer　of　jet　impingement　using　the　water　has　been　carried　out,　whose　results　also　have　been　achieved.　The　results　at　the　stagnation　point　showed　that　good　consistences　for　water　are　found　between　the　current　results　and　some　results　from　classical　correlation,　which　indicate　the　accuracy　and　reliability　of　experimental　equipment　and　method.　Meanwhile,　the　influence　of　temperature　for　heat　transfer　characteristics　of　stagnation　has　been　made　when　the　temperature　is　changed,　whose　results　show　that　thermophysical　properties　of　working　fluid　have　a　enormous　influence　on　the　Heat　transfer　performance.　The　experimental　results　in　this　paper　provide　a　necessary　technical　guarantee　for　the　study　of　heat　transfer　of　jet　impingement　utilizing　the　high　temperature　molten　salt.
