AI Technical Summary

Technical Problem

Under high temperature or high load conditions, the ambient temperature around the control board of a traditional air conditioner outdoor unit is prone to rise, resulting in insufficient heat dissipation efficiency. This may cause electronic components to overheat, degrade in performance, or even be damaged, affecting the stability and lifespan of the air conditioner.

Method used

A thermoelectric cooler is installed in the control area of ​​the outdoor unit of the air conditioner. The cold end of the cooler releases cold air to cool the unit, and a cooling fan works with the hot end of the thermoelectric cooler to exchange heat with the heat exchange area. An NTC temperature sensor is used to control the operation of the thermoelectric cooler and the cooling fan, thus optimizing the heat dissipation structure.

Benefits of technology

It effectively reduces the temperature of the control board, improves heat dissipation efficiency, avoids heat accumulation and high temperature in the control area, and ensures the stability of the control board and the normal operation of the air conditioner.

Abstract

This utility model provides a heat dissipation structure for an air conditioner outdoor unit, including an outdoor unit casing. Inside the casing are a heat exchange zone and a control zone. The heat exchange zone contains a condenser coil and a cooling fan. The control zone contains an electronic control board, a cooling fan, and a thermoelectric cooler. A ventilation grille is provided on the side of the outdoor unit casing corresponding to the control zone. The heat exchange zone and the control zone are separated by a partition with holes for mounting the thermoelectric cooler. The hot end of the thermoelectric cooler enters the heat exchange zone through these holes, while the cold end is located in the control zone. By placing the thermoelectric cooler in the control zone and utilizing its cold end to release cool air, the temperature of the control zone can be reduced, which is beneficial for cooling the electronic control board. Combined with the cooling fan, this improves the cooling effect and prevents heat accumulation and high temperatures in the control zone. Furthermore, the ventilation of the heat exchange zone accelerates the heat dissipation of the hot end of the thermoelectric cooler, ensuring that the thermoelectric cooler operates in optimal condition.
