Road 2 is connected to, and is avoided refrigerant under the action of heat exchanger fin rotary centrifugal force and is assembled on top, refrigerant is evenly distributed on and is changed
In backing, heat exchange efficiency is improved.
After refrigerant is from first runner 1 into third flow channel 3, since the sectional area that third flow channel 3 starts is smaller, system
Flow velocity is all than very fast under the effect of the pressure cryogen, and when entering the bigger third flow channel 3 of sectional area, refrigerant is to send forth
Form projects, and increases specific surface area of the refrigerant in third flow channel 3, increases heat exchange efficiency.
In third flow channel 3, blocking of the refrigerant by unhurried current structure, flow path not instead of straight line will be bypassed
On the one hand several bendings can reduce the flow velocity of refrigerant during around bending, keep refrigerant more in third flow channel 3
A period of time is retained, increases the heat transfer rate of refrigerant, on the other hand can break up refrigerant, enabling the refrigerant to will be in runner
Wall is full of, and increases the heat exchange area of refrigerant, improves heat exchange efficiency.
In heat exchanger fin rotary course, outside air is passed through from ventilation hole, on the one hand can reduce the resistance of heat exchanger fin,
On the other hand the contact area for increasing heat exchanger fin and outside air, increases heat exchange efficiency.
