I. test-cooling tablets for good or bad use of a dry cell test
The operation is: one hand holds the two sides of the cooling sheet, the other hand the wire of the cooling sheet is pressed on the battery poles (red line pressed on the positive pole and black line pressed on the negative pole), and if one side of the cooling plate is felt on the negative pole, it means that the cooling sheet is good and can work normally.
The working state of the cooling sheet is one of cooling and heating. when the cooling sheet is working, it is necessary to heat the heating surface well. it is strictly forbidden to electrify the cooling sheet for more than 2 seconds without cooling, causing the buyer to overheat and burn the film on his own account.The transmission of cold-to-cold chips must wait until the hot-and-cold sides are restored to room temperature (usually more than 5 minutes), otherwise it is easy to cause the circuit damage of the cold-to-cold tablets and the rupture of ceramic panels.
Third, when the cooling chip is used as a cooling source, the red-line power supply is positive and black-line power supply is negative, and the power supply requires switching power supply with a ripple coefficient less than 10%.The ceramic panel with wires is usually hot.If the red line is connected to the negative pole, the black line is connected to the positive pole, then the cooling sheet is hot and cold face adjustment.
Do not connect to the heat surface of the power supply when the radiator parts are not installled. the heat dissipation of the heat surface of the cooling sheet will cause the temperature to exceed the limit temperature of 100 degrees, and cause the cooling sheet to overheat and burn.The lower the temperature of the hot surface, the lower the cold surface temperature, the better the cooling effect.
V. the cold-cooling sheet is made of two ceramic panels and semiconductor materials combined by low melting point solders. it is fragile material. please take it lightly in the user's favor, do not touch it, let alone fall from high altitude, and avoid damage caused by the rupture of ceramic panels.
The naming rules of the cold-film model are made up of six parts.For example, tec1-12706
Part one: te is used to denote temperature difference electrical cooling components, which is abbreviated for thermo-electric
Part two: structure type, commonly used ceramic-type cooling tablets(Temperature difference electrical component interception area greater than 1mm2)In c, the small ceramic-type temperature differential-induced cooling element is also known as the micro-induced cooling element(Temperature difference electrical component intercept area 1mm2)In s, there is also a
