The experimental research of heat exchange for gas flow in the quasitriangular channel has been carried out. Experiments have been executed for a case of a constant temperature of a wall. A thermogram of the temperature field on outlet of a channel by the thermal imaging camera was registered. The visualization of the temperatures field with the use of the mesh with small cells has been performed. It was shown, that the dependence between the changes of a friction coefficient from Reynolds number for the quasitriangular channel is similar to the known dependences for the smooth pipe; the average Nusselt number have monotone correlation from unitless parameter Ψ, and this correlation lies higher of the dependence for the round channel.
