Hye everyone, I am new here.
I am a Master Student doing thesis regarding usage and market potential of copper capillary tube.

I need to identify the usage of capillary tube in the industry. Capillary tubes regarding to DIN are tubes from 1mm - 6.1mm..

Anyways, I know capillary tubes are used as expansion device (either as capillary expansion device or in thermostatic expansion devices).. It is also used in thermostats attached to the sensing element. Also from my research I found out that it is also used in heat exchanger. However, what I have read from books / internet, the copper tubes in heat exchanger are mostly 6mm tube and above. May I know where exactly is the capillary tube in heat exchanger??

What is the suction line capillary tube in heat exchanger? Is it the tube for refrigerant distributor outside the heat exchanger? Please help. Pictures are also very much appreciated!
