In this paper, we numerically investigate the thermoelectric properties of a triangle quantum dot connected to metallic electrodes using Green's function method in the Anderson model. Using the equation of motion method in the presence of Coulomb interaction in the Coulomb-blockade regime, the thermovoltage, thermocurrent and heat dissipation are calculated. Results show that the thermovoltage and thermocurrent have nonlinear behavior and their magnitude and sign of them can be controlled with the site energy and coupling strength of quantum dots. Also, the heat current is nonlinear and has an asymmetrical function with respect to the sign of bias voltage for all of the site energies of quantum dots. Results show that the heat current can be positive or negative for all of the site energies and it shows that heat current has a nontrivial zero for the nonzero voltages. These results can be useful to determine the performance of the nanoscale electronic devices to control heat dissipations.
