Abstract

Abstract A small-sized heat exchanger for separable air conditioner not only saving the electric power but also reducing the cost. The heat exchanger has tube banks provided on a predetermined upper section of the air conditioner main body. A plurality of heat exchanging fins are placed under the tube banks and connected to a plurality of heat transfer tubes. Both the tube banks and the heat transfer tubes are supported by a pair of guide plates placed on opposed sides of both the tube banks and the heat transfer tubes. The tube banks include a plurality of small diameter tubes and a plurality of distribution manifolds. The manifolds are connected to bundles of small diameter tubes respectively.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 186 words
In a heat exchanger for an air conditioner comprising an air conditioner main body having a plurality of heat exchanging fins and a plurality of heat transfer tubes, a cross flow fan mounted in back of the air conditioner main body, and a casing for incasing both the air conditioner main body and the cross flow fan, wherein the improvement comprises: tube banks provided on a predetermined upper section of said air conditioner main body including: a plurality of small diameter tubes; a plurality of distribution manifolds, said manifolds being connected to bundles of small diameter tubes respectively, thus to divide the plurality of small diameter tubes into several bundles of predetermined numbers of said tubes; and a plurality of connection tubes connecting said distribution manifolds to each other, thus to cause said manifolds to communicate with each other; said heat exchanging fins placed under said tube banks; said heat transfer tubes connected to said heat exchanging fins; and guide plates placed on opposed sides of both said tube bank and said heat transfer tubes for supporting both the tube banks and the heat transfer tubes.
