Description

Low-temperature cooling ultrasonic device

Technical Field

The utility model relates to an ultrasonic device, especially a cryogenic cooling ultrasonic device.

Background

Ultrasonic devices are widely used in the fields of chemistry and biomedicine. In the chemical field, nanoparticles usually require ultrasound at low temperature to have good dispersion effect. In the biomedical field, the ultrasound process also needs to be performed at a lower temperature in order to not denature the target protein. However, during the ultrasound process, the ultrasound probe may release heat, affecting the ultrasound effect. The low-temperature ultrasonic device commonly used at present is that ice blocks are added outside an ultrasonic container to reduce the temperature. The experimental device has uncontrollable temperature and large experimental error. If the environmental temperature is high or the ultrasonic time is long, the ice blocks can be heated and melted in the ultrasonic process, so that the ultrasonic effect is poor, the liquid level is increased, and the ultrasonic container is unstable. In the experimental process, ice blocks need to be continuously replaced and redundant ice water needs to be removed, so that the steps are complicated, and the experimental efficiency is influenced.
