| Summary: | Elaborating gyroscopic well systems of orientation by the fact that precision gyro sensors, as a rule, provide necessary accuracy only under the conditions of thermostating with the error which does not exceed grade fraction is complicated. It should be taken into account that well device operation at its descent lifting in the well environmental temperature changes continuously. For the object under thermostating conditions, inherent heat release occurs, variable in a general way. The result is unsteady thermal duty of the device operation. In the context of the discussed problem optimal solution is considered to be the application of active thermostating system including two actuating organs - the heater and the cooler based on thermoelectric cooling modules. Control of the heater and the cooler using PDM can be represented as an unified actuating organ providing either heat flow or outflow. To determine minimum available power of the heater and the cooler by calculation of thermal unit diagram, the use of the the principle of electrothermal analogy is proposed. All the parameters determining system dynamics are proposed to be found by computer simulation. An electrothermal model of thermoelectric module is constructed. |
