1. It does not need any refrigerant, and can work continuously. There is no pollution source, no rotating parts, and no rotary effect. No sliding parts are solid pieces. It has no vibration, noise, long service life, and is easy to install.
2. The semiconductor refrigeration chip has two functions, which can both cool and heat. The refrigeration efficiency is generally not high, but the heating efficiency is very high, which is always greater than 1. Therefore, using one chip can replace the separate heating system and refrigeration system.
3. Semiconductor refrigeration chip is a current transducer chip. Through the control of input current, high-precision temperature control can be achieved. With temperature detection and control means, remote control, program control and computer control can be easily realized, which is convenient for forming an automatic control system.
4. The thermal inertia of the semiconductor cooling fin is very small, and the cooling and heating time is very fast. Under the condition of good heat dissipation at the hot end and no load at the cold end, the cooling fin can reach the maximum temperature difference within one minute of power on.
5. The reverse use of semiconductor refrigeration chips is thermoelectric power generation, and semiconductor refrigeration chips are generally suitable for power generation in the middle and low temperature areas.
6. The power of a single refrigeration element pair of semiconductor refrigeration chips is very small, but it can be combined into a stack. If the same type of stack is combined into a refrigeration system in series or in parallel, the power can be very large, so the refrigeration power can reach a range of several milliwatts to tens of thousands of watts.
7. The temperature difference range of semiconductor refrigeration chip can be realized from positive temperature 90 ℃ to negative temperature 130 ℃.
