A large flow microchannel reactor chip

Abstract

The invention discloses a large-flow microchannel reactor chip, which comprises a bottom plate, through grooves are opened at the outer ends of the bottom plate, and expansion strips and moisture-proof strips are respectively fixedly connected to the inner and outer ends of the inner walls of the four through grooves, and the bottom plate The outer end of the lower surface of the lower surface is fixedly connected with a connecting frame, the middle part of the lower surface of the bottom plate is integrally formed with an orifice plate, the lower surface of the orifice plate is evenly and fixedly connected with a silicone grease tube, and the lower surface of the connecting frame is fixedly connected with a cover plate. The detachable moisture-proof structure can keep the chip in a humid environment without water damage. The moisture-proof structure can be replaced frequently to keep the chip dry. Compared with the existing technology, the moisture-proof performance is greatly improved. Grease cylinder, and the silicone grease cylinder can be disassembled to replace the silicone grease, avoiding the need to use a scraper to scrape off the old silicone grease every time the silicone grease is replaced, and also solves the problem of uneven application.

Description

technical field [0001] The invention relates to the relevant field of microreactors, in particular to a large-flow microchannel reactor chip. Background technique [0002] A microreactor is a three-dimensional structural element that can be used for chemical reactions made of a solid matrix by means of a special micromachining technology. The microreactor needs to use an electronic chip to control various parameters. The existing reactor chip is moisture-proof and There is no special treatment for heat dissipation to adapt to the environment of chemical plants. Heat dissipation silicon grease is mostly used for heat dissipation of chips, and silicon grease needs to be replaced frequently. It is very troublesome to replace silicon grease for existing chips, and only semi-sealed chips are used for moisture protection. Obviously, the moisture-proof performance is not enough to face the humid environment, so that the chip is damaged by the environment for a long time. In view of...
