Patent-family-89157815

A hydrogen refueling station comprising a heat exchanger in which a hydrogen pipe part is coiled around a center filler. The hydrogen pipe part enters and leaves said heat exchanger via a top flange and a bottom flange. The heat exchanger comprises a coolant entrance and a coolant exit. The coolant entrance enables a coolant to enter the heat exchanger in a direction perpendicular to the longitudinal direction of the center filler. A coolant pump is configured for introducing the coolant into the heat exchanger via the coolant entrance thereby establishing a radial swirling coolant flow in the heat exchanger around said the center filler towards said coolant exit. The swirling coolant flow is fluidly in contact with the said hydrogen pipe part and thereby facilitating exchange of heat between said swirling coolant and said gaseous hydrogen flowing in said hydrogen pipe part.
