Abstract: Provided is a double tube type heat exchange pipe, in which a gas or liquid coolant passes through a flow path hole to cool an inner tube, the gas or liquid coolant supplied through through-holes of an outer tube is collected in a first collecting groove formed in an inner tube, the gas and liquid coolant is guided to a spiral groove of the inner tube and continuously collides with a plurality of protrusions to undergo heat exchange and be cooled, and the cooled gas and liquid coolant is collected in a second collecting groove of the inner tube to be discharged to the outside via the through-hole of the outer tube.
