Latest Patents

One of Weiwei Zhang's latest patents is a heat exchanger. This invention discloses a heat exchanger where an end cover is assembled and fixed to a port of a first header or a second header in a lengthwise direction. The end cover includes a body and a first opening formed in the body. The body features a second cavity and a first recess, with the first recess having a first bottom wall close to the first opening. This bottom wall is equipped with a third opening that communicates with both the first opening and the second cavity. Notably, the first opening is positioned farther away from the inner cavity of the first or second header than the second cavity, and the open area of the first recess is larger than that of the third opening.

Another significant patent is the valve clip with coatings and valve clamping system. This application provides a valve clamping system that includes a pushing device and a valve clip with coatings. The valve clip consists of a push rod, coatings, a proximal clamping plate, and a distal clamping plate. The proximal and distal clamping plates extend radially outwardly relative to the push rod, with the distal clamping plate connected to the push rod. A valve holding space is formed between the two clamping plates, allowing the push rod to drive the distal clamping plate to expand radially. The proximal clamping plate can also expand toward the distal clamping plate, enabling it to clamp a valve tissue received in the valve holding space.
