2results about How to "Avoid drift phenomenon" patented technology

The utility model relates to the technical field of muffler, concretely relates to a small hole and sound flow combined muffler, including outer cylinder, bottom closing plate, blowoff pipe, muffler, oval punching head, cylinder inner flow divider and export flow divider, bottom closing plate and outer cylinder fixed connection, blowoff pipe and bottom closing plate fixed connection, muffler and bottom closing plate fixed connection, oval punching head and muffler fixed connection, cylinder inner flow divider sets up in the middle section of outer cylinder, export flow divider sets up in the top of outer cylinder, export flow divider includes two first steel sheet and steel wire mesh, two first steel sheet and outer cylinder fixed connection, steel wire mesh and two first steel sheet fixed connection, through above -mentioned structure's setting, solved the prior art, when handling high -pressure gas of large flow, the airflow distribution in the muffler is often uneven, leads to the noise reduction effect of some areas to be poor, gas drift phenomenon is serious, and further produces the problem of greater noise and vibration.

This utility model provides a heat exchanger with high heat exchange stability, including a heat exchange shell and heat exchange tubes. The heat exchange shell has a heat exchange inner cavity, and the heat exchange tubes are installed in the heat exchange inner cavity. The heat exchange shell has a refrigerant connector, and the heat exchange shell is connected to a refrigerant inlet pipe and a refrigerant outlet pipe. The inner end of the refrigerant connector is inclined towards the center of the heat exchange inner cavity and is mounted on the heat exchange shell, and has an outer end. The refrigerant inlet pipe is adapted to be installed on the outer end, so that the refrigerant inlet pipe is inclinedly connected to the heat exchange inner cavity. The refrigerant outlet pipe is installed on the top of the heat exchange shell, and the inlet end of the refrigerant outlet pipe penetrates the heat exchange shell and extends to the bottom of the heat exchange inner cavity. The structure is simple, and the uniform assembly position and angle ensure a uniform distribution of the refrigerant exhaust and intake fluid states. It also reduces the risk of weld breakage caused by vibration during refrigerant operation, increases operational stability, and ensures the product's performance.
