Patent Spiral-Panel Type Water Cooler for Furnace Transformer

I Description of spiral-panel type water cooler for furnace transformer oil

Spiral panel type water cooler is a state-of-art heat exchanger widely used in petroleum, chemical, food, metallurgy, machinery industries, etc.

Spiral panel type water cooler adopts special structure by using two spiral rolled panels to form spiral heat exchanging channels, full counterflow heat exchanging, huge cooling surface area.

II Characteristic of spiral-panel type water cooler for furnace transformer oil

2.1 High heat transfer coefficient: can reach max. 3300Kcal/m2.h °C, 1-3 times than thatof traditional pipe type cooler.

2.2 Few heat loss: compact structure, small occupation, small exposed surface

2.3 Reliable structure: two complete panel spiral rolled and argon welded, no mixing

2.4 Self-cleaning: Liquids flow inside spirally, self cleaning, few deposit.

III Main techncal data of spiral panel type water cooer for furnace transformer oil

3.1 Nominal pressure: 0.6MPa (our test pressure is 1.25 times than this nominal pressure)

3.2 Allowable working temperature: 1°C~200 °C  for carbon steel cooler; 1 °C ~300 °C  for stainless steel cooler

3.3 Flow speed: more than 1m/s

3.4 Material of cooler: stainless steel or carbon steel

3.5 Can be used singlely or combined, parallel or serial

3.6 Mounting method: both horizontal and vertical

3.7 Cooling capacity: 40kW ~ 1250kW
