A heat exchanger comprising plates of thermoplastic tubes arranged in a way which minimizes the thermal resistance at the outer surface of the tubes preferably to not more than 5 times the resistance to heat transfer at the inside of the tubes. The tubes are arranged in the tube plates in groups that can be flat or slightly wavy, such as undulating in a periodic manner, or offset with open spaces facing groups of tubes in alternating rows. This is done in a way that maximizes turbulence outside the tubes and minimizes vortices which can trap coolant in the interstices between tubes.
