The paper presents an original design of compact heat exchanger which uses principle of parallel agent flow through a variety of parallel slotted channels. Heat transfer element is a both-side finned tube made by deformational cutting method. Coolant flow is organized in hundreds gaps between external and internal fins on a half of length of a circle of a heat exchange element. Tests on various modes have shown heat exchanger capacity up to 7 kW with thermal heat transfer coefficient at 740 W/(m2K).
