Shanghai manufacturer direct evaporator plate heat exchanger professional production Defu Shandong

Plate heat exchangers are widely used in hot and cold liquid heat heating system, bath, air conditioning, hydraulic oil and cooling lubricants, chemical, pharmaceutical and other areas of exchange. The basic principle of the plate heat exchanger is to transfer heat, that heat hot fluid to cold fluid passes through the heat exchanger on the other side of the plate, so that the temperature of the hot fluid decreases, the cooling fluid temperature rise. Hot and cold fluid respectively, in the two-channel heat exchanger plates on both sides of the reverse flow, they are always in isolation, not in contact with each other mix. Welcome to Texas Kaiyuan heating Equipment Co., Ltd. Web site: http: //www.kyln.cn. Phone: 0534-2559996 plate heat exchanger plate heat exchangers are mainly sealed pads, clamping plates, guide rod, clamp screw and other component parts. Heat exchanger plates made of stainless steel plate pressing above it opened a four runner hole, pressed into V-shaped corrugated middle, around the sides and circulation of pore pressure seal groove, the seal groove is sealed pads. Heat transfer plate by two guide rods positioned aligned, two clamping plates which have clamping screw down plate heat exchanger and seal pads pressed to form a heat exchange cavity hot runner. The adjacent heat exchanger plate of V-shaped ripple in the opposite direction, the point of contact with each other support during installation. V-shaped corrugated medium and these support points tortuous fluid flow reversal in its interior, fully turbulent flow, heat transfer efficiency plate heat exchanger and therefore very high. Also heat exchange plate sheet thickness thin, thermal resistance is small. Fluid plates on both sides of medium flow distribution is more balanced, but also makes the heat more fully. Plate heat exchanger compared to other types of heat exchangers, heat transfer efficiency, low cost, light weight, small footprint, easy installation and removal. But the heat temperature is lower, under pressure is small. Assembled form plate heat exchanger are suspended and not suspended, suspended during the installation of the heat exchanger plates are suspended on the guide rod, the guide rod beam structural model using a large plate heat exchanger, Under the guide bar rectangular tube structure. Smaller models of the upper and lower guide plate heat exchanger using the yuan steel rods. Movable clamp plate is relatively fixed clamping plate, in the installation and removal can move on guide rods, larger models equipped with rollers on it, in order to reduce the resistance movement. The main features of the plate heat exchanger: heat transfer coefficient high heat transfer efficiency plate heat exchanger generally 3000-6000w / m2 ℃, is 3-5 times that of other heat exchangers. Compact and small footprint, saving infrastructure investment, the effective heat transfer area per unit volume of the largest light weight. Washable washable convenient installation general day can achieve pure countercurrent heat exchanger take full advantage of the temperature difference between the two fluids, heat recovery up to 95%, the strongest ability to handle small temperature difference, for low temperature waste heat recovery, air conditioning in summer heat, Other types of heat exchangers are not competent. Wide range of applications in almost all areas of heating, cooling, evaporation, condensation, heat sterilization process. Defu heat exchanger all year product warranty.
