Experimental device for measuring dissolution heat of ice

The utility model discloses an experimental device for measuring dissolution heat of ice, which comprises a calorimeter, a blocking cover arranged at the upper end of the calorimeter and a speed reduction mechanism arranged on the calorimeter and used for reducing the descending speed of ice blocks, and the speed reduction mechanism comprises a speed reduction slide way fixedly connected to the inner wall of the calorimeter. The speed reduction slide way is arranged in a spiral shape, baffles are fixedly connected to the two sides of the speed reduction slide way, and a throwing mechanism used for throwing ice blocks to the speed reduction slide way is arranged on the plugging cover. According to the utility model, through the arrangement of the speed reduction mechanism, under the throwing action of the throwing mechanism, the ice block spirally descends to the cup bottom of the calorimeter, so that the impact force of the ice block on water in the calorimeter in the descending process is effectively reduced
