Description

one

The invention relates to temperature recovery systems with a variety of sensitive elements that change their volume with a change in the temperature of the setting. 5

Known thermometers are known that use a signal from a temperature sensor to turn off a device that creates a heated thermostatically controlled volume when it cools down (overheating) l. These thermostats have a reduced reliability caused by the presence of electro-automatic singing.

The closest to the invention to the technical essence is a thermostat containing a base, a thermostatable chamber with a temperature sensor with a movable wall installed in it, a source of hot air flow regulator placed between the thermostat and a thermostat. measure and foundation

However, due to tbggO) that the pschvngng teoloyordo perynHTt Ja tepsed flow is connected to the flexible wall of the temperature sensor through (EastOnpc and thermostat) 25

The last camera is movable relative to the base of the system.

Increasing the size and weight of the thermostat chamber causes large mechanical stresses in the junction rod, causing harmful distortions of the thermal Ptszg regulator. In addition, large pressures transmitted through the flexible wall cause the temperature to melt and the thermostat decreases.

The aim of the invention is to improve the accuracy of thermostating;

This is achieved due to the fact that the heat flow regulator is made in the form of two heat and power plates, between which there is a movable heat conductor connected to the temperature sensor machines, and the thermostatically controlled chamber is connected to the heat flux retor through the source of cold (heat).

In the drawing, depicting a perfect thermostat, general view.

Claims (2)

The thermostat contains a thermostatically controlled chamber 2 coated with solubilization 1, in which there is filler 3, which changes its phase state at a temperature of setting, a temperature sensor 4 with a movable wall 5. A 6 x heat (heat) source is connected to the thermostatted chamber 2 , for example, a thermoelectric battery, a thermistor with a positive T.S. etc. which may be ND "H8fls, cascade. A heat flux regulator 8 is located between the source in cold (heat) and the base 7, stdata from stationary heat-conducting plates 9 and 10 and moving heat pipe 11, having good thermal contact with the stationary Plate lOs, for example due to the other edges 12 entering into each other, and separated by an adjustable gap from the plate 9. To reduce the value of thermal resistance, the gaps between the moving and non-moving parts can be filled with a liquid circuit, which is made of dead-wall 13 and 14, with a moving wall 5 oedinen iSf rod pressed by spring 16 against washer 171 which prizhimaegs to 11 under thermally vkzhnomu stronger spring 18. Osnseanie 7 may comprise an additional heat source 19 {germogilvktr ical battery germorezistor etc.). In this case, the cold (heat) source 6 may not be used, and the plate 9 is connected directly to the chamber 2. When using the filler 3, which reduces its volume during the measurement. The heat flux 8 must be inverted so that the wall 10 would be connected to the source of heat (heat), and the plate / 9 - with the base 7, In the off state, the movable wall 5 is stretched on the MOBILE heat pipe 11 pressed to the plate 9 After the heat source (cold) source 6 in the air, the filler 3 and the thermostat inside the chamber 2 are cooled and partially frozen. The movable wall 5 at the same time shrinks the rod 15 until it is supported on the washer 17. As the spring 18 presses the sh 17 and moves to the movable heating 11, then with further freezing of the ice in Germany, the rod 15 mixes the washer 17 together with the movable heat conductor 11 as one more peleye. At the same time, the gap between the plate 9 and the movable heat pipe 11 increases, which causes an increase in its thermal resistance and an increase in the temperature of the heat release side of the cold (heat) source 6 of equilibrium, in which its cooling capacity is equal to the heat leakage from the environment. If, as a result of any deviation of the external conditions from the calculated ones, the liquid in the thermostatically controlled chamber 2 is completely freezing, then with an emphasis on a heat pipe of aa 11 in the plumbing Yu rod 15, overcoming the spring force. 18, pushes ibaibu 17 away from the MOBILE heat pipe 11, which prevents the thermostat from breaking. Thus, the proposed thermostat provides an increase in the accuracy of thermostatic control by reducing the pressure in a two-phase medium, filling our thermostatted volume, and increasing the strength of the structure, due to the fixed fixing of the thermostat's main masses. Claims of thermostat containing thermosc; This camera has a temperature sensor with a movable wall installed in it, a source of cold (heat) and a heat supply controller. I drip placed between the thermostatically controlled chamber and the base, characterized in that, in order to measure the accuracy of the VIA thermostat, the heat flow controller is made in the form of two heat-conducting plates, between which there is a movable heat conductor connected to the movable wall of the temperature sensor, and the thermostatically controlled chamber is connected with heat regulator through a source of cold (heat).
