Cooling Scheme For The Ultrasonic Transducer Of Mask Machine

At the beginning of 2020, a large-scale outbreak of a new type of coronavirus occurred in the country. By April, the epidemic has covered the world. Isolation at home and safe travel have become a rule that everyone abides by. In this urgent matter, masks have become an indispensable item, and there is even a shortage of demand.

   Under such circumstances, a large number of patriots have emerged and they have been involved in the production of masks. The large-scale production of masks that work overtime day and night has made the mask machines too difficult to bear. The main problem is that the heating problem of the ultrasonic transducer is the most serious. . Heating generally has the following three reasons: 1. a. The welded parts will generate heat or the material that is acted on by ultrasound will generate heat; b. The mold/welding head/die/tooling will generate heat after working for a long time; c. Amplifier/Length rod length Time work will generate heat; this heat will eventually accumulate and be transferred to the transducer. 2. The transducer itself cannot convert 100% of all high-frequency electrical energy into mechanical energy, and part of the power loss is also converted into heat. 3. A slow increase in the temperature of the transducer will cause its own performance to change, and the gradual deviation of the best matching state of the transducer will result in a gradual decrease in the performance of the piezoelectric ceramic wafer, and cracks and damages in severe cases. This process makes the performance state of the transducer worse, which in turn leads to a faster temperature rise, which is an irreversible vicious cycle state. Therefore, conditions must be created so that the transducer can be cooled well, air-cooled at room temperature, and better, cold air-cooled.

As the first batch of star companies to resume work and production, Chengdu Hop Technology Co., Ltd. is naturally also always paying attention to the domestic epidemic situation, hoping to do its part when necessary. At present, the heat generation of ultrasonic transducers in the production of mask chains is a big problem that cannot be delayed. Ordinary fans are difficult to efficiently reduce the temperature. The HOP mobile air conditioner can just well reduce the high temperature of the transducer, so that the mask machine can Continuous high-efficiency production. Chengdu Hop Technology Co., Ltd. has focused on the development of air conditioners for 20 years. It uses imported Panasonic compressors to blow out the air-conditioning that is 10-15 degrees different from normal temperature. The machine does not need to be installed, plug and play. In the past two decades, the mobile air conditioners produced have been sold to dozens of countries and regions including the United States, Australia, New Zealand, Thailand, Vietnam, Taiwan, and Hong Kong. At present, it has helped 200,000 companies in producing countries around the world to achieve air conditioning needs, and has won unanimous praise from customers. In the future, Hop will continue to produce high-quality products, and continue to carry out technological innovation, optimization and perfection, and strive to become a brand worthy of customers' trust.
