Cooling driers with four unification heat exchangers, comprise that cooling driers comprises heat exchanger, heat exchanger comprises that forecooler, filter, evaporimeter, moisture trap Unified Global manufacture and design, and first half is evaporator section, adopts the plate heat exchanger, mid portion is cavity, the cavity Lower Half is moisture trap, and moisture trap partly comprises tube head, blade assembly, water stopping cap, pull bar, shell group, cavity the first half are the filter part, filter comprises tube head, filter core, pull bar, shell, decline is the forecooler part, adopts the plate heat exchanger.The synthetic comparison in equipment together of original smooth evaporimeter and forecooler has machine volume little, saves independent peace filter and moisture trap trouble.Have the twice division box, moisture trap and filter, a minute water effect is divided the water better effects if than independent silk screen.
As preferably, comprise that also refrigeration part comprises refrigeration compressor, refrigeration compressor is connected with air-cooled condenser, and air-cooled condenser is connected with device for drying and filtering, and device for drying and filtering is connected with evaporimeter by the evaporating pressure constant valve again.
As preferably, air-cooled condenser horizontal is installed in the casing top, and the below is provided with blower fan.Blower fan adopts the blowing form, meets cold air and enters from the below, the heat exchange principle that hot-air is discharged from the top after the heat exchange.
As preferably, the fin that air-cooled condenser adopts the nano-hydrophilic membrane material to make.Have good hydrophily, resistance to corrosion and automatically cleaning ability, gas-flow resistance is little, fin can increase compressed-air actuated flow-disturbing effect, heat exchange efficiency improves more than 1.1 times, hydrophilic fin can reduce the Wet Compression air drag, reduces crushing.Air-cooled condenser adopts overhead to install, the high hot compression refrigerating fluid of getting rid of from compressor be introduced into the top layer heat exchange copper tube again according to layer toward dirty, rationally adopted the radiating principle of heat; Blower fan adopts the air-exhaust type blower fan and gathers the temperature control of refrigeration pipe, and fan starting when its temperature reaches setting value lowers the temperature of air-cooled condenser, outside the hot blast remover apparatus, reaches best overall performance.
According to the cooling driers of the technical solution of the utility model, the triple oblique convection type designs of heat exchanger, unit volume has increased the refrigeration heat transfer rate, makes heat exchanger reach better heat transfer effect.The air ports temperature difference can reach in 3 degree, guarantees that the downstream pipeline can not produce dewfall, and causes pipeline to get rusty.The full stainless steel that adopts of heat exchanger part is made, and can be applicable to wrap the industry-by-industries such as food.
Equipment is provided with dual overtemperature protection, compressor internal protection and equipment overtemperature prote.Compressor internal protection: the i.e. pressure overload protection of compressor inside; The equipment overtemperature prote: namely can shut down during device compressor delivery temperature to 120 ℃, this shutdown needs again opening device of manual reset, plays like this effect of guarantee for equipment long-time running under various relative rugged environments.
