Tube Heat Exchanger Full Liquid Type
Evaporator for Air Conditioning
Self-developed products include dry type spiral baffle plate evaporator, flooded evaporator, built-in oil
separator condenser, sea water condenser, stainless steel heat exchanger, oil cooler, oil separator, gas-
liquid separator and liquid accumulator among others.
The spiral baffle plate evaporator is the latest product designed and made by Qiaoxin and has obtained
the national technical patents, which can save 20% in copper consumption and 30% in ferrous metals,
reach the total energy saving rate 30% after test and satisfy the national economic policy of industrial
upgrading, saving energy and reducing consumption and environmental protection.
The heat exchange tube uses copper pipe, nickel-copper alloy tubes, aluminum brass tube and stainless
steel tube as the material and the shell uses No.20 seamless steel tube and stainless steel tube.
The large production equipment includes 10 sets of CNC machining center, 8 sets of CNC tube expanders
, multiple copper pipe automatic straightening rotary cutting machine, copper pipe bender, CNC tapping
machine and automatic welding machine.
