The invention discloses an all-glass shell-and-tube type solar vacuum tube heat collector. The all-glass shell-and-tube type solar vacuum tube heat collector comprises an outer glass tube, a heat-absorbing glass tube and an inner glass tube. The all-glass shell-and-tube type solar vacuum tube heat collector is characterized in that a shell-and-tube type cavity body between the heat-absorbing glass tube and the inner glass tube forms a heated cavity of thermodynamic medium; the thermodynamic medium is heated for circulation in the glass shell-and-tube type cavity body, and the glass shell-and-tube type cavity body is also an inflow channel and an outflow channel of the thermodynamic medium, and the right end of the heat-absorbing glass tube is provided with at least two holes; the right end opening of the inner glass tube is provided with a silicone plug. The all-glass shell-and-tube type solar vacuum tube heat collector disclosed by the invention has powerful natural circulation performance, and also has the
