AI Technical Summary

Technical Problem

In the existing technology, vehicle air conditioners are quite noisy when they are working, making it difficult to achieve silent or low-noise operation, which affects the normal use of other vehicle functions.

Method used

A static pressure chamber is set up in the heat exchange system of an air conditioner. By introducing the heat exchange airflow into the static pressure chamber, its flow velocity is reduced, kinetic energy is converted into static energy, and noise is reduced.

Benefits of technology

It effectively reduces the noise from the air conditioner's vents, improves the comfort and operating efficiency of the air conditioner, and ensures the normal operation of other vehicle functions.

Abstract

The present application discloses a heat exchange system and an air conditioner. The present heat exchange system is used in the air conditioner. In the present heat exchange system, by providing a static pressure cavity, noise at an air outlet during operation of the heat exchange system is reduced. The heat exchange system comprises a first heat exchange cavity, a first heat exchanger, a first heat exchange fan, a static pressure cavity, a first airflow inlet, and a first airflow outlet; the first heat exchange cavity is isolated from the static pressure cavity, and the first airflow inlet is communicated with the first heat exchange cavity and is arranged facing the first heat exchanger; the static pressure cavity comprises a first end and a second end, the first end is close to an airflow blowing outlet of the first heat exchange fan, and the second end is provided with the first airflow outlet; the first heat exchange fan suctions a heat exchange airflow from the first heat exchange cavity, the heat exchange airflow is blown out into the static pressure cavity by means of the airflow blowing outlet of the first heat exchange fan, and is blown out by means of the first airflow outlet, and the flow speed of the heat exchange airflow in the static pressure cavity is reduced.
