Plate heat exchanger device is removable by a number of corrugated heat transfer plate, at regular intervals, by pressing the rubber gasket thereof. We mainly based structure to distinguish plate heat exchanger, which is based on the shape to distinguish, can be divided into four categories: ① detachable plate heat exchanger (plate heat exchanger called with gasket), ② welded plate change heat, ③ spiral plate heat exchanger, ④ coil heat exchanger (also known as cellular heat exchanger). More common gasket plate heat exchanger, plate heat exchanger, when plate assembly, alternating between the two groups, the board and the board with adhesive rubber sealing panel fixed, its role is to prevent fluid and leakage between the two plates forming the narrow net-shaped flow channel, the heat transfer plate pressed into a variety of corrugated shape to increase the heat transfer area and the rigid plate, and enables the formation of turbulence in the fluid at a low flow rate in order to achieve enhanced heat transfer effect. The four corners of the board holes to form a vent tube and a fluid distribution manifold, and flows into each of the two heat transfer medium flow path is formed for countercurrent or cocurrent flow through each of the heat exchange plates. Plate heat exchanger features:
(1) Small size, small footprint;
(2) high heat transfer efficiency;
(3) flexible assembly;
(4) metal consumption is low; Small
(5) of heat loss;
(6) disassembly, cleaning, maintenance convenience
(7) Plate heat exchanger drawback is sealed around the long, prone to leaks, only use temperature is below 150 ℃, under less pressure, the smaller capacity, if it is found to be disassembled clean sheet fouling.
Plate heat exchangers are widely used in metallurgy, mining, petroleum, chemical, power, pharmaceutical, food, chemical, paper, textile, shipbuilding, heating and other departments, can be used for heating, cooling, evaporation, condensation, sterilization, heat recycling and other various situations.

Bluetooth wireless technology is a short-range wireless communications the easiest and most convenient way between the two devices. It is widely used around the world, can wirelessly connect to mobile phones, portable computers, cars, stereo headsets, MP3 players and other devices. Bluetooth wireless technology is the most widely supported on the market today range, most feature-rich and secure wireless standard. Wireless Bluetooth headphone products currently on the market more, and wireless Bluetooth speaker is relatively small.
The so-called wireless Bluetooth speaker, actually refers to rely on Bluetooth transmission protocol as a carrier for data transmission speakers, because most mobile devices (cell phones, laptops, tablet PCs) are set to have a Bluetooth chip, do not need a data cable or audio cable that can quickly be identified, simple operation, easy connection. Wireless Bluetooth Speaker Bluetooth technology is applied in the traditional digital and multimedia speakers, so that users can remove the annoying wires to tie him down, freely listen to music in various ways. With the maturity of the development of wireless technology, and now the wireless Bluetooth headphone has a compact, wireless, portable and other characteristics. Wear a wireless Bluetooth headphone, you can write EMAIL while talking on the phone while you can talk on the phone while driving, you can while doing housework while talking on the phone, no annoying wires to tie him down! Just recently hit a wireless Bluetooth headphone support mobile advertising: the hands empty out your hands to do it the right thing.
By using Bluetooth technology products, it can remove the cable wound distressed home office. Via Bluetooth wireless technology, the office no longer see the messy wires, the entire office like a machine, like an orderly and efficient operation. PDA can be synchronized with shared calendars and contact lists with the computer, answer the phone when the computer can communicate with peripheral devices, employees can walk directly through the Bluetooth headset in the entire office, all of which are connected without wires.
