Abstract

PURPOSE:To disturb airflow around pipes in first row and improve the heat conducting performance of the heat exchanger by providing cylindrical members, having rough outer surfaces, in zigzag with respect to the pipes of the first row. CONSTITUTION:The cylindrical members 5, having cylindrical outer peripheral surfaces and arranged in parallel along the side rim of upstream side of plate fins 1 with intervals into directions intersecting with the flow direction of the airflow, are provided while the outer surfaces thereof are worked into rough surfaces so as to generate strong disturbed flow in the wake flow thereof. The cylindrical members 5 are arranged in zigzag with respect to the pipes 2a in the first row. When air is flowed into the direction A, the airflow is disturbed in the wake flow of the cylindrical members 5 by the same members 5 and eddy currents X are generated. As a result, the airflow around the pipes 2a in the first row is disturbed and the heat conducting performance around the pipes 2 is increased. Further, the outer surfaces of the cylindrical members 5 are rough, therefore, the disturbance is strong and large, therefore, the heat conducting performance as the heat exchanger may be improved remarkably. Ventilating resistance is increased slightly by the provision of the cylindrical members 5, however, most of the ventilating resistance of the heat exchanger, consisting of the plate fins 1 and the pipes 2, is occupied by the frictional loss of the plate fins 1, therefore, the resistance of the heat exchanger due to the configuration of the cylindrical members 5 is not increased so much.

As a result, this flow affects the second row of pipes 2b, disturbs the flow around the pipes 2b, and improves the heat transfer performance around the pipes. Similarly, a vortex (0
) disturbs the flow around the pipe 2C and improves the heat transfer performance around the pipe. However, the flow around the pipes 2a in the first row is not provided with anything to disturb the flow on the windward side, so the heat transfer performance around the pipes is not fully utilized. In other words, the conventional heat exchanger has a structure that disturbs the flow around the pipe on the windward side, so the heat transfer performance as a heat exchanger cannot be fully demonstrated.

4 is a fin collar. Reference numeral 5 denotes a cylindrical member having a cylindrical outer peripheral surface, which is arranged in parallel at intervals in a direction perpendicular to the wind flow direction along the windward side edge of the plate-shaped fin 1. The surface is roughened to create stronger turbulence in the wake section.

Further, the cylindrical members 5 are arranged in a staggered manner with respect to the pipes 2a in the − row. In the above configuration, the arrow (
When air flows in the direction of A), the cylindrical member 6 disturbs the flow in its wake, creating a vortex as shown by the arrow (X). As a result, the flow around the pipes 2a in the row is disturbed, the heat transfer performance around the pipes 2 is enhanced, and the performance as a heat exchanger is greatly improved. Moreover, since the outer surface of the cylindrical member 6 is rough, the strength of turbulence is large, and furthermore, the heat transfer performance as a heat exchanger can be greatly improved.

The transmission can be increased, and since the outer surface of the cylindrical member is rough, the strength of turbulence is also large, and the heat transfer performance of the heat exchanger can be greatly improved.
