Abstract (en)

[origin: EP2551622A2] A double tube type heat exchange pipe, in which a gas or liquid coolant passes through a flow path hole (101) to cool an inner tube (100), the gas or liquid coolant supplied through through-holes (201) of an outer tube (200) being collected in a first collecting groove formed in an inner tube (100), the gas and liquid coolant being guided to a spiral groove (102) of the inner tube (100) and continuously collides with a plurality of protrusions (103) to undergo heat exchange and be cooled, and the cooled gas and liquid coolant being collected in a second collecting groove (104b) of the inner tube (100) to be discharged to the outside via the through-hole (201) of the outer tube (200).
