This invention discloses a method of electronic accuracy controlling water temperature for electric heating apparatus, which immerses the heat sensitive resistor in water to detect the temperature, then outputting the data of resistance value change to computer data processing unit to obtain the function relationship of temperature change, which is used for real time monitoring the resistance value of heat sensitive resistor, when the temperature will reach the preset value, the power supply of heater disk will be cut off to avoid the temperature difference due to the afterheat and realize the accuracy temperature control.

The invention provides a temperature control system of a near space sealed cabin. The temperature control system comprises a cabin wall heat exchanger, a cold accumulation heat exchanger, a first bypass pipeline, a gas-liquid heat exchanger and an acquisition controller, wherein the cabin wall heat exchanger is arranged on a cabin wall of the sealed cabin for obtaining an out-cabin cold source; the cold accumulation heat exchanger is internally provided with a cold accumulation working medium, connected with an output end of the cabin wall heat exchanger through a liquid pipeline at an input end and provided with a first control valve at the input end or an output end; the first bypass pipeline is connected to two ends of the cold accumulation heat exchanger in parallel through liquid pipelines and provided with a second control valve; the gas-liquid heat exchanger is used for exchanging heat with the internal part of the cabin, connected with an output end of the cold accumulation heat exchanger through a liquid pipeline at an input end and connected with the input end of the cabin wall heat exchanger through a liquid pipeline at an output end; and the acquisition controller is used for controlling the first control valve and the second control valve. The temperature control system can satisfy temperature demands of a near space sealed cabin manned flight in ascending, stop and descending processes, and solves the problem of influence on the in-cabin temperature by external environment change distance.

The invention discloses electric heating area control valve. It includes valve body, valve rod, hot resistance, thermal sensor, spring, outer cover, union body, reversing valve body, double sided seal ring, and thermostat package. The reversing valve body is set in the valve body. And its upper end is set joint. Its lower end is set the union body. The limited inner chamber of the outer cover, union body, and reversing valve body is set the hot resistance, thermal sensor, valve rod and spring. The valve rod is set the double sided seal ring. The thermostat package is connected with hot resistance electrical property. The invention can automatically control area flow quantity to adjust the temperature.

The invention discloses a phase change energy storage sealed wallboard with various temperature control and adjustment structures, which comprises a surface decoration board, a phase change energy storage board, a sound insulation board, a bottom plate and an installation assembly. The surface of the energy storage board, the side of the phase change energy storage board away from the surface decoration board is provided with a sound insulation board, the side of the sound insulation board away from the phase change energy storage board is connected to a bottom plate, and the installation assembly is arranged on the bottom board away from the One end of the phase change energy storage board. The phase change energy storage sealed wallboard with various temperature control and adjustment structures is equipped with a sound insulation board, which effectively reduces the interference of noise to users through mechanical methods. It is fixed by adhesion, and can also be fixed by traditional methods, which is more convenient to use. The end of the heating wire wound on one side of the plate can be sealed and fixed by the wire end fixing mechanism.

The invention discloses an insulated pure electric passenger car fuel cell box with temperature adjustment performance, which includes a box body, the box body is made of a silicon carbide composite material, and the preparation process is as follows: the silicon carbide and a porogen are mixed uniformly according to a certain ratio, Then add ethanol solvent for grinding, grind evenly, dry, and sinter to obtain macroporous silicon carbide; take silicon powder, macroporous silicon carbide, water, binder and anti-precipitation agent, stir at high speed to obtain a mixed material, and then place the mixed material in Press molding in the mold, dry the green body, and then carry out nitriding sintering in the nitriding chamber to obtain a box with a rough surface; the box is soaked in liquid paraffin, then the box is taken out to cool and polished, and finally the surface of the box is Spray a coat of paint. The battery case of the present invention is prepared from a silicon carbide composite material and has a certain strength. At the same time, because the surface of the case body is dipped with liquid paraffin, and the surface of the case body is coated with a layer of paint, the prepared battery case has good temperature and temperature. thermal conductivity.
