Abstract
This utility model relates to a TEC-based rack air conditioning device. The cooling components, from the outside to the inside, include a cooling fan, heat dissipation fins, a thermoelectric cooler, cold-end fins, and a cold-end fan. Multiple thermoelectric coolers are provided and fixed to a mounting plate. The inner sidewall of the housing is close to the rack to be cooled. The inner wall of the housing has a cold-end air inlet and a cold-end air outlet. A U-shaped air duct is provided inside the housing, with one end connected to the cold-end air inlet and the other end aligned with one side of the cold-end fins. The cold-end air outlet is aligned with the cold-end fan. A hot-end air inlet is provided on the sidewall of the housing, and a hot-end air outlet is provided on the outer wall, respectively aligned with one side of the heat dissipation fins and the cooling fan. This device uses thermoelectric coolers for cooling, overcoming the problems of large size, heavy weight, and high noise in existing rack air conditioners on the market. The U-shaped air duct design at the cold end as the air inlet improves the heat exchange efficiency within the rack. PID control technology allows for precise temperature control within the rack, making it suitable for various application scenarios.
