Embodiment Construction

[0006] Referring to accompanying drawing below, the present invention is further described in conjunction with embodiment:

[0007] The present invention is made of high-temperature-resistant glass, including one horizontal tube (2) and two vertical tubes (3). There is a scale for adding water on the raised part. The opening (1) is used for adding water and draining water. There are bases (4) at the lower ends of the two longitudinal tubes. The distance between the horizontal tube and the base can be recognized by the outer flame part of the alcohol lamp.

[0008] When using the present invention, a certain scale of liquid is added from the opening, the alcohol lamp heats the horizontal tube, and the vertical tube is held by hand to experience the phenomenon of liquid heat conduction. The invention can also do liquid thermal expansion experiment; observe the change of liquid volume from the scale. The present invention can also be used for liquid evaporation experiments: o...

Abstract

The invention relates to a liquid heat conduction test device which is made of high-temperature-resisting glass. The liquid heat conduction test device comprises a horizontal pipe (1) and two longitudinal pipes (3), wherein the horizontal pipe and the longitudinal pipes are vertically communicated, one longitudinal pipe is higher than the horizontal pipe and is provided with an opening. Scales for water are arranged on the part, higher than the horizontal pipe, of the longitudinal pipe, and the opening (1) is used for water feeding and discharging. Bases (4) are arranged at the lower ends of the two longitudinal pipes respectively. The distance between the horizontal pipe and the bases enables outer flames of an alcohol lamp to reach the horizontal pipe.

Description

technical field [0001] The invention relates to the field of physical and chemical instruments, in particular to a liquid heat conduction experimental device. Background technique [0002] At present, there is no liquid heat conduction experimental instrument in the laboratory, and it is difficult to buy corresponding instruments in the instrument market. In order to improve teaching quality and improve student performance, the present invention is specially designed. Contents of the invention [0003] The present invention is made of high-temperature-resistant glass, including one horizontal tube (2) and two vertical tubes (3). There is a scale for adding water on the raised part. The opening (1) is used for adding water and draining water. There are bases (4) at the lower ends of the two longitudinal tubes. The distance between the horizontal tube and the base is that the outer flame part of the alcohol lamp can burn. [0004] The invention has the advantages that t...
