HeatPort_aThermal port for 1dim. heat transfer (filled rectangular icon) 
SystemModel["Modelica.Thermal.HeatTransfer.Interfaces.HeatPort_a"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This connector is used for 1dimensional heat flow between components. The variables in the connector are:
T Temperature in [Kelvin]. Q_flow Heat flow rate in [Watt].
According to the Modelica sign convention, a positive heat flow rate Q_flow is considered to flow into a component. This convention has to be used whenever this connector is used in a model class.
Note, that the two connector classes HeatPort_a and HeatPort_b are identical with the only exception of the different icon layout.
