2results about How to "Reduce contact gap" patented technology

This utility model discloses a multi-segment spliced ​​metal heat sink, comprising multiple detachably connected metal heat sink segments. Each metal heat sink segment includes a main substrate and heat dissipation fins vertically disposed on the surface of the main substrate. Adjacent metal heat sink segments are connected by a convex-concave mating structure. The convex-concave mating structure includes a boss at the rear end of the preceding metal heat sink segment and a groove at the front end of the following metal heat sink segment. The boss and the groove form an interference fit. The contact surface between the boss and the groove is coated with a thermally conductive adhesive layer with a thickness of 0.05-0.2mm. The multi-segment detachable design allows for flexible combination of lengths to adapt to different needs, saves space during transportation, and reduces costs by requiring only the replacement of damaged segments during maintenance. The convex-concave mating structure combined with the thermally conductive adhesive layer, along with the snap-fit ​​mechanism working in tandem with the convex-concave structure, reinforces the connection from the vertical direction, preventing loosening due to vibration and ensuring stable heat dissipation.

This invention discloses an atmospheric pressure reactor for high-viscosity materials, comprising a support assembly, a lifting device, a servo motor, a bath, a sealing and fixing assembly, a stirring assembly, and an electrical controller. The support assembly has a square sliding tube as its column, and the support rod is machined with a suitable slide rail, forming a support structure where the sliding tube is fixed and the slide rail drives the motor to lift and lower. The sealing and fixing assembly consists of a cover plate, a spring pad, and a bracket, enabling the sealing and fixing of the beaker and the directional recovery of volatile gases from the reaction. The stirring assembly has threaded stirring blades, and the servo motor achieves closed-loop control of the stirring speed via an encoder. This invention solves the problems of easy beaker rotation, uneven stirring, and uncontrolled speed in high-viscosity material reactions, improving experimental accuracy and operational safety. It is compatible with various reactor vessels and suitable for atmospheric pressure synthesis reactions of high-viscosity materials.
