The electrocaloric effect was first discovered in Roche salt in 1880.

[0003] For example, the Chinese utility model patent with publication number CN206057229U discloses "A device for directly measuring the electrical caloric properties of materials". In this device, a measuring cavity for placing the material to be measured, a gas conveyor, a power supply, a heat flux sensor and a temperature acquisition display are included; an air supply port is provided on the measuring cavity; the gas conveyor conveys temperature-controlled gas into the measuring cavity through the air supply port to heat or cool the ambient temperature in the measuring cavity and the material to be measured to a preset measurement temperature; the power supply is used to load a periodic voltage to the material to be measured after the ambient temperature in the measuring cavity reaches the preset measurement temperature, so that the material to be measured generates heat or cold; the heat flux sensor is attached to the surface of the material to be measured, and is used to collect the heat flux on the surface of the material to be measured and transmit it to the temperature acquisition display; the temperature acquisition display is used to obtain the temperature change of the material to be measured according to the heat flux collected by the heat flux sensor, and then obtain the electrical caloric properties of the material to be measured, thereby improving the accuracy and reliability of the electrical caloric performance measurement.

[0004] Although the above-mentioned measuring device has certain advantages in measuring the performance of electric cards, it still has certain disadvantages:

[0027] Here’s how it works:

[0028] First, before use, place the ceramic electric card to be measured next to the measuring device and wait for measurement;

[0029] Second, when in use, the ceramic electric card needs to be placed in the heat preservation box 4, and the motor 778 is started to rotate the motor 778. When the motor 778 rotates, it drives the round rod 3 776 to rotate. When the round rod 3 776 rotates, it drives the round rod 2 774 to rotate through the pulley group 779. When the round rod 2 774 rotates, it drives the right adjustment plate 772 to rotate to the right, so that the right adjustment plate 772 is in a vertical state. At the same time, when the round rod 3 776 rotates, it drives the gear 2 777 to rotate. When the gear 2 777 rotates, it drives the gear 1 775 to rotate. When the gear 1 775 rotates, it drives the round rod 1 773 to rotate. When the round rod 1 773 rotates, it drives the left adjustment plate 771 to rotate to the left, so that the left adjustment plate 771 is in a vertical state. At this time, the top of the heat preservation box 4 is in an open state;

[0030] Third, when the top of the insulated box 4 is in the open state, the electric push rod 74 is driven to drive the movable rod 78 to move downward. When the movable rod 78 moves downward, it slides along the sliding groove 1 73. At the same time, when the movable rod 78 moves, it drives the left end of the connecting rod 72 to move downward, so that the connecting rod 72 rotates with the support block 71 as the rotation center. When the left end of the connecting rod 72 is downward, the right end of the connecting rod 72 rotates upward. When the right end of the connecting rod 72 rotates upward, it drives the sliding block 75 to rotate. When the sliding block 75 rotates, it slides along the sliding groove 2 76. When the sliding block 75 moves, it pushes the support plate 6 to move upward, so that the support plate 6 moves to the top of the insulated box 4;

[0031] Fourth, when the support plate 6 moves to the top of the heat preservation box 4, the ceramic electric card to be tested is placed therein, and the electric push rod 74 is driven to move upward, and the support plate 6 is moved downward by the cooperation of the connecting rod 72, and returns to the top of the measuring body 5, and then the left adjustment plate 771 and the right adjustment plate 772 are controlled to rotate toward the middle by the motor 778, so that the heat preservation box 4 is in a sealed state, and then the high voltage source instrument 2 and the temperature controller 3 can be used to measure the ceramic electric card;

[0032] Fifth, when the measurement is completed, repeat the second and third steps to remove the ceramic electric card from the thermal insulation box 4 to complete the measurement.

[0033] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
