Abstract
The invention relates to a tunneling effect super-sensitivity electromagnetic control constant-temperature system mainly composed of a tunnel electrode (1), an amplifier (2), a magnetic core switch (3), an electromagnet (4), a spring (5), a fixed point (6), a right slide bar (7), a heating slideway (8), a heating device (9), a heating resistor (10), a control power supply (11), a cooling resistor (12), a control switch (13), a cooling device (14), a variable-frequency air conditioner (15), a left slide bar (16), a cooling slideway (17), a fixed iron block (18) and a magnetic core power supply (19). A change in temperature causes the thermal expansion and contraction of the tunnel electrode (1) so as to change the distance between the two electrode plates of the tunnel electrode (1) so that the magnitude of the current flowing between the two electrode plates changes. The change can cause the electromagnet (4) to move horizontally left and right to automatically adjust the operating conditions of the heating device (9) and the cooling unit (14) to compensate for the temperature change.
