An internal circulation cooling structure for an electronic water pump
ActiveCN224282944Uprevent leakageeasy maintenancePump componentsPump installationsCooling effectCooling fluid
This utility model relates to the field of electronic water pump technology, and in particular to an internal circulation cooling structure for an electronic water pump. It includes a support base, a housing assembly movably connected to the top of the support base, a limiting component movably fitted onto the outer wall of the housing assembly, a charging interface on one side of the housing assembly, a pipe groove on the top of the housing assembly, a drain assembly movably fitted onto the inner wall of the pipe groove, and an electronic pump body movably fitted onto the bottom of the drain assembly. This device provides an easily disassembled and reassembled protective housing structure for the electronic water pump, enabling rapid repair and replacement of parts in case of malfunction. The drain assembly allows for timely discharge of coolant, thus removing the cooled coolant from the device to dissipate heat, improving the cooling effect of the device, and providing convenience and feasibility for coolant circulation.

Precast concrete component connection structure and precast concrete component connection device
ActiveCN224281348UQuality assuranceImprove construction qualityBulkheads/pilesArchitectural engineeringPrecast concrete
This utility model discloses a connection structure and device for precast concrete components. The connection structure includes a connector and at least one opening groove on the outer edge of an end plate on the precast concrete component. The opening groove penetrates the upper and lower surfaces of the end plate, and the connector is embedded in the opening groove. The connection device includes two end plates located at the ends of adjacent precast concrete components, and also includes the connection structure. The opening grooves on the outer edges of the two end plates of the two precast concrete components are vertically aligned, and the two end plates are connected together by the connector embedded in the two vertically aligned opening grooves. This utility model has a simple structural design, enabling rapid and reliable connection of multiple precast concrete components.

Lead frame with high bonding strength, manufacturing process of packaged device and product thereof
ActiveCN114464589Bnot misplacedSolve problems such as breakageSemiconductor packageStructural engineering
This invention relates to the field of semiconductor packaging technology, and more particularly to a high-bonding-strength lead frame, a manufacturing process for packaged devices, and related products. A high-bonding-strength lead frame includes a frame body and frame units spaced apart from the frame body. Each frame unit includes a die-attach island, a first functional pin, a second functional pin, and a fixed pin. The first functional pins are symmetrically distributed on the left and right sides of the die-attach island, and one end of each first functional pin is connected to the frame body. This high-bonding-strength lead frame improves the interlocking effect between the functional pins, the die-attach island, and the molding compound. Furthermore, the die-attach island exhibits good stability, effectively preventing delamination. This solves the problems of existing lead frames, such as pins easily stretching and causing misalignment and delamination, die-attach islands easily lifting, poor soldering due to insecure soldering, and delamination on the frame surface.
