Typical Model Specification Book

HT064200(40*40)

Product Introduction

The HT (High Temperature) series is designed for harsh high temperature environments and long-lived applications. It is assembled from high-strength bismuth telluride thermoelectric materials, high thermal conductivity and high insulation DBC (direct bonded copper) ceramics and high-temperature solder, and is suitable for high-temperature environments, hot and cold cycles and industrial-grade products. There are over 400 typical models to choose from. Products that can customize aluminum nitride and double-sided metallized ceramic substrates.

，67 High reliability, ordinary application lifespan of more than 10 years Biological and medical instruments High temperature resistance, suitable for 80℃ environment Test and analysis instrument RoHS CPU

Installation Note

■ Use DC (DC) power supply; the voltage/current should be less than the device maximum voltage/current;■ Before use, the refrigeration plate should be installed on the hot-end radiator, and generally use a fan and radiator to dissipate heat or water-cooled heat; ■ Use and store in an environment less than 80°C; ■ Pay attention to stress balance during installation to prevent side pressure or any form of impact;

Quick product selection

1. Determine whether there is a heating source for the refrigeration object (space, liquid, solid) and what is the heating power;

2. What is the ambient temperature (℃) used and the target temperature (℃) of the refrigeration object;1 and 2 items quickly determine whether semiconductor refrigeration sheets are suitable.

3. Determine the maximum product size that the product can apply. From the perspective of performance, the larger the size, the better the refrigeration effect;

4. If the refrigeration power is required, you can consider using multiple pieces in series and parallel;

5. If the input voltage exceeds 12V, it is recommended to consider using a multi-piece series solution;

6. The better the heat dissipation effect, the better the cooling effect;

7. The larger the temperature difference, the lower the refrigeration efficiency;

The four main performance parameters of semiconductor refrigerators refer to:Maximum current Imax: refers to the constant thermal surface temperature Th and load Qc is 0, the current value when ΔT reaches ΔTmax is the maximum current value. Maximum current Umax: refers to the constant thermal surface temperature Th and load Qc is 0, the voltage value when ΔT reaches ΔTmax is the maximum voltage value. Maximum temperature difference ΔTmax: When the heat absorption of cold surface is 0, the temperature of the hot surface is constant. When I=Imax, the maximum temperature difference can be reached between the cold surface and the hot surface. Maximum heat absorption QCmax: constant hot surface temperature, when the temperature difference between the cold surface and the hot surface ΔT=0, the heat that the cooling surface can absorb when I=Imax.
