A heat exchanger includes a fluid inlet, a fluid outlet, a first plate, and a second plate. A third plate is disposed between the first plate and the second plate; a first fluid channel is formed between the first plate and the third plate, and a second fluid channel is formed between the second plate and the third plate. The heat exchanger has a first end and a second end; the fluid inlet is close to the first end of the heat exchanger and communicated with the first fluid channel; the fluid outlet is close to the first end of the heat exchanger and communicated with the second fluid channel; and the first fluid channel and the second fluid channel are communicated at the position close to the second end of the heat exchanger.

Provided are a reinforcer () used for a plate heat exchanger () and a plate heat exchanger (), the reinforcer () being used to reinforce an area around an opening () of at least one heat exchange plate (). The plate heat exchanger () comprises multiple heat exchange plates (); a heat exchange space formed between adjacent heat exchange plates () of the multiple heat exchange plates (); a heat exchange channel () formed between the heat exchange plates (), wherein the heat exchange channel () is used for a heat exchange medium to flow into or out of the plate heat exchanger (), and is constituted by openings () in the multiple heat exchange plates (); and a reinforcer (), used to reinforce an area around an opening () in at least one heat exchange plate (). The plate heat exchanger () can alleviate or prevent deformation or cracking of a backing plate () and a heat exchange plate () of the plate heat exchanger (), especially the two heat exchange plates () adjacent to the backing plate (), in the area around the heat exchange channel ().

Reinforcer used for plate heat exchanger and plate heat exchanger

An integrated eliminating device and its method for initial runoff pollution is provided, wherein a plurality of the water receiving pipes for collecting initial runoff are gathered and connected to the first water reservoir, one end of the water inlet pump is connected with the first water reservoir via the water receiving pipes, and the other end of the intake pump is connected with an water inlet opening of the rice field; the rice field is divided into a plurality of sub-parcels in a shape of long stripes, a regulating gate is set. An outlet of the rice field is communicated with the second water reservoir and which is communicated with the water inlet opening of the rice field via the reflux pump.

The present invention provides a preparation method of fluoromethyl 1,1,1,3,3,3-hexafluoroisopropyl ether by reacting CHFX with 1,1,1,3,3,3-hexafluoroisopropanol in the presence of acid-binding agent. The reaction can be also preformed in the presence of solvent and/or phase-transfer catalyst. The present method has the advantages of simple reaction, manageable control condition, high material conversion and product yield, and the product can be easily separated. The obtained fluoromethyl 1,1,1,3,3,3-hexafluoroisoprophyl ether can be used as a safe inhalation anesthetics.
