<p>Provided is a heat exchanger, which takes into account the relationship between each parameter and determines the optimal value of each parameter to maximise the heat exchange capability per unit weight of finned tube heat exchangers and so is miniature, light weight and has excellent heat exchange capacity, and a heat pump that uses said heat exchanger. The heat exchanger is provided with multiple heat transfer tubes, which are arranged in the vertical and longitudinal directions leaving spaces in the radial direction and are arranged in such a manner that lines drawn between the centres of neighbouring tubes in the vertical and longitudinal directions form equilateral triangles, and multiple corrugated heat transfer fins, which are arranged leaving spaces in the axial direction of the heat transfer tubes. V1 is the outer diameter of the heat transfer tubes, V2 is the vertical separation of the heat transfer tubes, V3 is the fin separation of the corrugated heat transfer fins, V4 is the fin thickness of the corrugated heat transfer fins, V5 is the height of the corrugations of the corrugated heat transfer fins and any of V2, V3 or V5 are within the bounds of a predetermined formula.</p> |
