SL type tube cooler

SL type tube cooler is the introduction of Japanese manufacturing technology products, the heat sink cooling pipe copper rolling, small volume, large heat exchange area; the spiral plate, so that the flow of oil into the spiral uniform connection flow, overcomes the heat generated in the transmission angle of baffle, high heat transfer efficiency and pressure loss small.

There are two flow processes and four flow processes in SL tube cooler. There are two kinds of oil flow: large flow (deflector large lead) and small flow (deflector small lead) two. According to the requirements of matching.

SL tube type cooler conditions: the inlet pressure is less than 1.0Mpa, the temperature is lower than 70 DEG C, oil viscosity is less than 50 centistokes, oil-water flow ratio in 1:1.5 working condition, the temperature drop is less than 8 DEG C, the heat exchange coefficient is up to 300Kcal/m2.h. DEG C.

Cooling water: fresh water use: the oil side pressure less than 1MPa water side pressure: less than 0.5MPa

Selection method: calculate the heat exchange Q

1. calculate Q=cpq (T1-T2) according to oil temperature requirement and flow rate

C - oil specific heat capacity p - oil density Q - oil flow T1 - oil inlet temperature T2- oil outlet temperature

2. according to the calorific value calculation of the hydraulic system
