Abstract

PURPOSE:To reduce draft resistance and to decrease a noise level, by a method wherein a plurality of guide vanes are disposed throughout the entire periphery on the multivane blower side of a heat exchanger, and the flow of the air from the multivane blower is directed in a direction extending orthogonal to each part of the heat exchanger. CONSTITUTION:A heat exchanger 1 is constituted such that a plurality of copper pipes 4 are interposed in a number of aluminum fins 5, aligned parallel to each other at intervals, and are located opposite to each other and in a manner to surround the whole periphery of a multivane blower 1. A guide vane 6 is secured to the copper pipe 4 on the multivane blower 2 side of the heat exchanger 1, and the vane is disposed, taking the direction of the curve of the guide vane 6 into consideration, so that the flow of the air from the multivane blower 2 is directed in a direction extending orthogonal to each part of the heat exchanger 1. This constitution causes the flow of the air from the multivane blower 2 to be uniformized as shown by an arrow mark by means of the guide vane 6 and enables the air to collide with each part of the heat exchanger 1 at right angles, resulting in reduction of draft resistance and in reduction of the generation of noise.

６の曲線の向きを考慮して配設する。The heat exchanger 1 is constructed by inserting a plurality of copper pipes 4 through a large number of aluminum fins 5 arranged in parallel at intervals, and expanding and fixing the pipes.As shown in FIG. Two parts are arranged facing each other so as to surround the entire circumference of the multi-blade blower 1. Guide vanes 6 are fixed to the copper pipe 4 on the side of the multi-blade blower 2 of the heat exchanger 1, and the guide vanes 6 are fixed so that the flow of the wind from the multi-blade blower 2 is guided to each part of the heat exchanger 1 in a perpendicular direction. Lay it out considering the direction of the curve.
