Abstract

The invention discloses a water-bath heating device with an interlayer. The device comprises an outer shell and an inner shell. The inner shell is sleeved with the outer shell. The outer shell is in a cylindrical shape. The lower end of the outer shell is in a semispherical shape. The lower end face of the outer shell is provided with a plurality of heating protrusions in an arc shape. The radian of the heating protrusions is 2.35. A connection cover is arranged between the upper end face of the inner shell and the upper end face of the outer shell. The connection cover is provided with a liquid inlet and an air outlet. The air outlet is in a conical shape. The outer surface of the inner shell is provided with auxiliary protrusions. The auxiliary protrusions are wound to the shell of the inner shell in a cylindrical spiral shape. The cylindrical spiral distance of the auxiliary protrusions is 1 / 6 of the height of the inner shell. The cylindrical spiral angle of the auxiliary protrusions is 27.5 degrees. The water-bath heating device has the advantages that defects in the prior art can be overcome, and structural design us reasonable and novel.

Description

technical field [0001] The invention relates to a water bath heating device with an interlayer, which belongs to the field of teaching equipment. Background technique [0002] Fill a large container with water first, then place the container to be heated into the container where the water was added. Heating a large container of water is achieved by heating the water in the large container and then transferring heat (heat transfer) through the water to the container that needs to be heated to achieve the purpose of heating. Because at one standard atmospheric pressure and water without any impurities, the condition for water to reach the boiling point is 100 degrees Celsius, but it needs to absorb more heat to change from liquid to gas. In the water bath method, the water in the beaker can only have a temperature of 100 degrees Celsius before it turns into water vapor, which cannot provide more heat for the water in the test tube, so the liquid in the test tube cannot boil. ...
